INTRODUCTORY.

We present our customers and those whose names have been given us with our descriptive pamphlet for 1872.

Having now been established over thirty-five years in the construction of machinery in this particular line, and knowing most of the old and new improvements which have been a success and those which have failed, we are offering, after almost a constant course of labor, mill machinery of undoubted superior qualities. And now we invite the attention of those interested to the articles of our designing and make, fully believing a careful investigation and comparison with the work of any manufacturer will convince them of its excellence. Our work being represented in OVER ONE THOUSAND FLOURING MILLS is some evidence of its practical merits. No experiments, but get the best. We have files of letters and statements that tell of the costly experiences of those having bought new and untried machinery.

The mill of to-day of whatever dimensions must be simple, compact, efficient, durable and cheap.

THE FOLLOWING POINTS

have claimed our special study to obtain the best results in the different locations, and purposes required.

1st. The best wheat scouring and separating machinery.

2d. The quality of burr stones required, best speed, draft and form of furrows, and best mode of driving them.

3d. Numbers of cloth, amount of bolting surface required, best arrangement of numbers, &c.

4th. Propriety of regrinding, how best to grade the offal for this purpose, as well as other requirements of flour mills.

COMBINED HUSKS

with two to four run of stones varying from two to four feet diameter, and all in one substantial frame, spindles being long and arranged for the gearing and lower part of husk to be in the basement of the mill-house on an independent foundation, are made complete in our works, carefully put up and adjusted, marked, taken apart, small pieces boxed and otherwise prepared for shipment and ease of putting up. This plan was first adopted by us in the year 1867; since that time we have put out considerably over one hundred run of stone on this plan, all receiving the highest commendations of the owners.

OUR PORTABLE MILLS

are in extensive use, but by careful observation we have found the means of improvement, and within the last few years have revised our patterns, and we say, with entire confidence, all things being considered, that we make the best heavy husk portable mill in the market, they having none of the objectionable features so common in mills of this class.

PARTICULAR ATTENTION

is directed to OUR COMPLETE GRINDING AND BOLTING FLOUR MILL adapted to the special demands of a custom mill. Those now made have all the improvements of value to the present date, and furnished at a price so reasonable that every town or neighborhood of sufficient demands can be supplied; good flour and yield guaranteed.

SELF TRAMMING, DRIVING AND BALANCE IRONS

as improved, are extensively used, and in brisk demand. These are no new and doubtful experiment. See the cuts and description, and the defects of other modes of driving irons will readily be understood. We are prepared to execute

DRAWINGS AND PLANS

with description, bills of material required in the construction of mill-house all ready to receive the machinery, showing also the location of mills and machinery in the building. This is of special advantage, as it can be turned over to the carpenter or contractor for execution, thus saving trouble in knowing the cost before you begin, as well as knowing where to strike.

OUR ADVANTAGES.

Our whole attention is devoted to this particular line of manufacturing, with special tools, machinery and permanent buildings built and adapted expressly for the purpose, at a great expense. We are thus enabled to conduct with system and accuracy the production of good work. We have advantages in location, as a glance at a map of the States will show; we are central, in ready access to lumber, coal and iron, (other makers both east and west of us are supplied in a great measure, some altogether, with hard lumber from our State.) We have good Railroad shipping facilities in all directions, and purchasers can have their work safely delivered almost at their own doors at low shipping rates.

With these advantages we are able to compete with any factory, east or west, saving time, money and risk to the purchaser.


MILL STONES.

FACE OF MILL STONE.

This is one of the specialties of our business. It has been built up from small beginnings to one of the largest west of New York. We keep a large stock of burr blocks from which to make selections. Hence if we should not have on hands, built up, the sized stone or quality that is wanted, we can give our customers just what they need on very short notice. Our facilities for turning out first-class work of this kind, are equal to any in the west. Having in our employ men experienced in the manufacture and use of burrs, we are able to furnish our customers just the quality of goods they need for their particular class of work.

BACK OF STONE.

We are well aware of the importance of a good mill stone to profitably flour wheat, and give this department the most careful attention. For a description of our method of building and backing up runner stones, we refer the reader to the article following, under the head of “Building and Balancing Runner Stones.” Where our customers prefer to do all the mill-wright work in their mill, we are prepared to make in addition to the burrs, such shafting, gearing, spindles, irons and machinery as they may need.


Building and Balancing Stones.

We put all runner stones on a point or cock-head, and keep them in balance while “backing up;” consequently they are as near in standing and running balance as they can be, by this means. We have testimony to the fact, that a number of stones we have made (all balanced upon the old plan of a cock-head at the center,) are in such perfect balance that if the wheat is exhausted in the hopper, the face of the runner will not touch the bed-stone. The importance of balancing on the true principle, is mostly overlooked. In a mill properly balanced, the stones will keep a better grinding face with one-half the time and labor required if they are not thus balanced. Particular attention must be paid to keeping the runner in balance, as after leaving our works, the cement dries out in such a manner as to sometimes throw the runner out of both standing and running balance. For a description of the means we provide to do this important work of balancing, see the cuts and description under head of “Standing and Running Balance.”

We put iron backs on our under-runners, to protect the stone from wearing out of balance.


Standing and Running Balance.

Millers as a rule know that a stone in standing balance is not always in running balance, and vice versa, yet they are well aware that a stone should be in both. The reason these two balances do not always exist at the same time, or why the light side of a stone standing should seem the heavy side on running, is not clearly understood, and hence the difficulty in obviating the trouble. The importance of a correct standing balance and at the same time a true running balance, cannot well be over-estimated. Suppose the balancing weights in a runner are so adjusted that the stone stands in balance on the cock-head when raised above the bed-stone, but on starting, instead of its face remaining true and running steady, one side droops, and it runs with an apparent vibration or oscillation of the face. It will be found, however, upon examination, that it will always run with the same side low—going to show that the difficulty is centered in one certain point.

In these cuts are shown the improved balance boxes adopted by us. The one on the right is the box complete. They are placed in the runner with the rounding part in contact with the band, with the lid of the box a little below the plaster back. The figure to the left illustrates the inner adjustable box and screw for adjusting the same when in the stone. It will be noticed it has two parts divided by a partition. The cover to this inner box shown in the middle figure is secured with a screw, and fits down upon the box and close over the division, so that either side may be used when the weight is wanted at a point between any two of the balance boxes. We put five of them in a runner stone. This number is deemed entirely sufficient. They are made of cast-iron and fit up in good style, the wrought screws being all tapped into the iron. We find this balance box gives the miller entire control of the runner, and easy to operate, simply by removing the curb and letting the stone rest in position. A wrench is all the tool needed; the weights when in position are not subject to derangement, as those ordinarily used.

Now that we have the means explained by which this important work is to be done, next comes the question, How shall I do it? First, we would say, put the runner in standing balance in the usual manner, and lowering the required weight to the bottom of the boxes. In mills with the old style of stiff driving irons the spindle and driver must be carefully trammed to the runner, as well as a proper bearing and a good fit of the cock-head into the cockeye; unless this is attended to it will be no use to proceed. Where our self-tramming driving irons are used, the process of putting in a balance will be a pleasure instead of a long disagreeable process, and it will be more perfect than is possible with any other appliance for this purpose.

The runner being in standing balance, place two boards planed evenly and ⅜ of an inch in thickness between the stones, (they may be 4 to 8 inches wide) allowing the ends to project sufficiently to fasten securely to a block or piece of timber fastened to the husk; place them about midway between the spindle and outer edge of stone, and put the stone in motion, letting it down upon the boards until its face runs steady and true; then turn off the plaster back perfectly true with the face, from a firm rest properly supported; now try the standing balance again. By turning off the back it may have been changed. Next find the light side of the stone by elevating the runner from the boards, and run it as fast as it will bear without too much vibration, as in cases where the stone is much out of balance the full speed should be approached gradually in the process. Hold a pencil against the rest plank and approach it slowly until it touches the turned back of the stone, say 4 to 6 inches in from the band or skirt. It will of course mark the side which runs high. The principle or real cause of this side of the stone running high is that the center of gravity or weight on this side is too low, (below the cock-head and point of suspension,) while the center of weight on the side that runs low is too high and above the center. To change this so as to bring the center of weight of each side respectively on the same level, is what we must accomplish.

As we know which side of the stone was high, now take, say two to six pounds, as the case may require, of iron, broken into small pieces, or shot, and take one-half of the amount and put into the inside box screwed to the top of the box on the side that runs high, and the other half in the box or boxes opposite, and lowered by the screw into the bottom of the balance box. Then test the stone and make a new mark, add weight carefully until the face runs true up to the full grinding speed. Be careful to divide the weight, as it may be added, so as not to disturb the standing balance.

Standing balance is simply an equal weight on all sides.

Running balance is having the center of gravity just as far from the face on one side as the other.

Irregular motion, and no matter how fast, will not affect the runner when balanced as we have explained.

If this important item is properly attended to, as well as keeping the stones in good flouring face, there will be less killing of the life of flour, and allowing middlings and unclean bran to escape. The value of the flour, both as regards nourishment and health, depends on the amount of nutritious, aromatic and saccharine properties retained in the flour which the wheat contains.

This result depends upon the flouring process the meal has been subjected to between the stones. On the amount of these properties in the flour also depend the weight and sweetness of the loaf when baked; likewise its light and white qualities when used for any purpose.


BOLTING CLOTHS.

There is a great deal said and published by those who furnish cloths, concerning the merits of the brand of cloth they sell, and demerits of others, so that millers are at a loss where to buy, when there is so much difference of opinion. When bolting cloth is wanted, all we can ask is to address us for samples to examine. If the cloth is ordered at once, and you want privilege of examining at express office before paying for same, please state it in the order. In the examination of Bolting Cloths parties are often led astray; some brands of the French and Swiss appear even, smooth and heavy; they are well sized with a kind of gum and sugar of lead, but when used awhile their bad qualities are betrayed by the uneven and fuzzy appearance.

The cloth kept in stock and for sale by us is the brand of “Dufour & Co.’s Old Dutch Anchor,” acknowledged by the most experienced mill-wrights and millers to be THE BEST. We have it imported direct by the only importer of this kind of cloth in the United States, and get it as low as any of our competitors. We have tested this cloth, not alone by long use, but by thoroughly washing and rubbing out all the sizing from a piece of this, as well as the other brands, and comparing carefully the weights and texture of each before and after the process. As the result we have found more silk in the Dufour Cloth than any other brand, as well as more firmly locked thread and even texture. We make cloths up in large quantities; have at times ten to fifteen on the way. We require the length of the reel, number of ribs, measurement around the reel, and distance from center to center of ribs, to enable us to make a good fit.


UNDER RUNNER PULLEY MILLS.

The above engraving shows our Portable Under Runner Mill, as improved. For grinding wheat, corn, feed, or flouring middlings, they are inferior to none. The runner is balanced upon a steel point or cock-head, projecting into a steel seat. Argument is no longer necessary to prove to intelligent millers the advantages of a cock-head mill over those having the runner stone secured rigid to the spindle. The driving irons in this mill are those shown under head of “Self-tramming Mill Irons.” No mill is perfect without them; with them they are more desirable for wheat grinding than any other under-runner mill.

The bed stone is stationary in the upper part of the husk frame, and is turned over on heavy hinges when necessary to sharpen the burrs. Four stiff rubber springs around bolts, are provided above the bed stone-frame, holding it down while grinding, for the important duty of allowing said bed-stone to yield up in case any hard substance enters between the stones. In this way we prevent the liability of breakage, and overcome the very popular objection to all other mills having the under stone to run. In addition we provide a metallic bush arranged to oil collar of spindle while mill is running. The curb is made of pine staves, and banded with neat iron bands. We furnish either damsel or silent feed as desired. The runner has a cast iron back to prevent any inclination to wear out of balance. The husk is made of hard wood and very strong. Many other points of excellence could be mentioned. The improvements are protected by Letters-Patent.

GEARED MILLS.

OUR UNDER RUNNER GEARED MILLS

Are substantially the same as set forth on page 14, excepting they are provided with heavy gearing, horizontal shaft, pulley and boxing lined with anti-friction metal. The gear is faced off in a lathe before the cogs are put in, the pulley is turned and balanced, all being fitted up in the best manner from new patterns, strong and in good proportion. We have the best and smoothest running geared mill in the market.


UPPER RUNNER PULLEY MILLS.

This cut represents our Portable Upper Runner Mill. The heavy runner in addition to being built in balance is provided with five improved standing and running balance weights, adjustable with screws. (See under head of “Standing and Running Balance.”) This mill has the self-tramming irons set forth under its proper head; improved silent feed rig; wrought iron spindle with steel ends; steel cock-eye in runner stone; a tram step to tram by means of screws; the oil fountain bush and followers; pine stave curb or hoop banded with iron under walnut finish; stones faced and furrowed, of a good selection of French burr, of sharp even quality, and other additions and advantages not necessary to mention, all made complete with pulley as shown in the cut, or gear as shown on page 16, and secured in a strong ash husk frame. The step-irons used in this mill admit of our using a much longer spindle without making top of mill higher than usual. The principal improvements on this mill have been secured to us by two distinct Letters-Patent.

ALL OUR PULLEY MILLS

Are furnished with our improved low down Set Screw Step, giving a spindle one-fifth longer than any other mill with same height of hopper, and constructed in the ordinary manner.

With this step the spindle is trammed by means of set screws, thus making it more readily and accurately adjustable, at the same time avoiding the liability of getting out of tram. This step is so constructed as to avoid changing from its true position or out of tram, when the runner stone is raised or lowered by the lighter screw. The husks of these mills are made of ash timber, strongly bolted together with wrought iron joint bolts. We furnish turned iron pulleys balanced and keyed to the spindle, so they can be raised or lowered at pleasure. The curbs around the runners are of the kind shown and described under head of “Mill Curbs or Hoops.” The feed rig, either our improved silent, or shoe and damsel, as may be wanted by the purchaser, or for the purpose required.


Attaching and Driving.

It will generally be found most desirable to drive our pulley mills from a horizontal shaft and pulleys, with reel belts and tightning pulleys in a movable frame, or quarter-twist belt.

Place the mill upon a solid floor or firm foundation with the bed-stone level; cleat around the posts, and bolt through two of the lower ties; if room is precious a platform can be placed over the belt or belts running from the line-shaft to the mill. This shaft should be from thirteen to fifteen feet from the mill spindle, to give sufficient length of belt.

The center of the mill pulley and driver must not be in line, but as follows: When the reel belt plan is adopted, place the center of the mill pulley four or five inches below the top of the driving pulley that runs from the mill, and the side of the mill pulley that runs towards the driving pulley in line with the center of the driving pulley, then place the idle or tightning pulley in a sliding frame on the under side of the slack belt near the driving pulley, and of the proper height and angle to lead the belt squarely on the mill pulley.

When locating the mill to run by “quarter twist belt,” place thus: Upper or lower side of the driving pulley, which runs towards the mill, should be five or six inches above the center of the burr pulley, and the side of the burr pulley that runs towards the driving pulley must be in a line with its center. In attaching the bolt it will be observed that its position depends somewhat upon how the elevator foot and cooling conveyor are placed. It will be found best in most situations to put the cooling conveyor and elevator foot entirely below the floor. It is a good plan to set the Portable or in fact any kind of a mill on a foundation entirely below and independent from the floor of the house. The reel belt plan of driving from a pulley on a horizontal shaft, even if a large one, will make no edge strain on the belt whatever, and in stopping and starting is of great convenience. We have it shown in a small way in the cut, Fig. 3, under head of “Complete Grinding and Bolting Mills.” Where we furnish the mills, we always, when requested to do so, send draft and plans showing how to set up and arrange all, so that it will be a success, and without additional charge.


GEARED MILLS

Are furnished with wood and iron gearing—wooden cogs in the driving wheel. This does away with the noise and deafening clatter of the ordinary, or all iron geared mills. (See under head of “Gearing,” and “Under Runner Geared Mills.”) These cogs are of wide face, thus having a large bearing surface, and wear but slowly. Where there is one mill the shaft is long enough to receive the pulley and one journal box outside. We often put three run of burrs, two wheat and one corn, upon one continuous shaft. This makes a very compact arrangement. In this case the mills are detached by slipping the pinion or wheel out of gear, on a sleeve provided for the purpose.

SINGLE REEL BOLT.

SINGLE REEL BOLT—Complete, and Dimensions.

(See preceding page.)

Our bolts are so well known that a full description seems superfluous. Their constant use for fourteen years has suggested some marked changes, which together with a brief outline of the bolt itself, we will describe. The object gained is a more efficient bolt for custom work, either for a Portable Mill or any flouring mill however large or small, where a bolt is wanted specially adapted to the demands of custom grinding; at the same time a bolt that can be shipped to any point on a navigable river or railroad in the United States or Territories. We have already sent a number of them into Northern Minnesota and Wisconsin. Also, Texas, Kansas, Georgia, &c., &c. When so ordered they are taken apart and boxed, previously marked how each part belongs, and drafts and description of how to set it up, sent so that one at all skilled can put it up in the mill and have it ready to run in two to three days time. For those residing within a few hundred miles of our works, we mostly send on open cars or boat, well protected by paint and varnish, and out of the great number shipped within ten years past, have not had a single one at all damaged that we know of. They are made in large quantities, the parts being duplicated and cut out from patterns, and by machinery adapted to the purpose. The lumber contained in them is thoroughly seasoned, and selected of the best quality. The parts usually sent with them unless otherwise ordered are:

1st. All the gearing and shafts required, with supporting frame and bearings for the elevator head, spout, gear and shafts.

2d. Extra heavy cloth of Dufour & Co.’s Dutch Anchor brand made up to fit the reel, with strips of ticking to come in contact with the ribs of reel, and proper arrangement of numbers to make flour that will bear inspection. This is generally sent by express in a separate package.

3d. The elevator complete, as follows: forty feet of 4½-inch leather or gum belt, thirty 4-inch heavy tin, iron banded, cups, with improved copper clasp fastenings, head and foot with turned pulleys in them, including an outside pair of bevel or spur wheels or turned pulley to receive power. (See cut of elevator head and foot under head of “Elevator, Cups and Fastenings.”)

4th. A cooling conveyor geared by suitable wheels to the shaft in foot of the elevator, so that it can be located in any direction to suit the situation. To fill some special orders we have put the cooling conveyor on top of the chest; in most cases it is best to have it below. The frame work of the bolt is made of hard wood and well bolted. Conveyor for flour and one for returns full length of bolt; conveyor flights are of hard wood; cut offs are provided so that one-fourth, all or any degree of the flouring cloth may be used for fine flour, at the option of the miller.

PORTABLE MILL AND BOLT.

In our portable Mill and Bolt we have condensed all the advantages required of a custom mill in making a prime article of flour and much better suited for the purpose. We have not been sparing in the material necessary to make every part strong and durable, and they will bear to be continually used with a strong power without any part yielding in the least. The bolts are arranged for making all the cut-offs for changing the grade of the flour, thus using more or less bolting surface, or making more or less returns, as may be found necessary. It makes a quick and even discharge of flour from the flour spout, there are no hoppers or anything for the clogging of flour, and every customer gets his own flour from his own wheat. This is of great advantage, and if not pretty fully accomplished creates dissatisfaction with customers. The Bolts in connection with our Mills are of ample capacity when the grain is in proper condition to make good flour. They are made much larger and in more roomy chest than ever before. They are supplied with our improved percussion apparatus. This has now been in use in its present style for over ten years, with perfect success. It is composed of three sets of hinged arms, or knockers, three in each set, secured to every alternate rib of the reel inside, gently tapping the ribs on the downward or empty side of the reel, thus not forcing the flour through the cloth, but dusting out and unclogging it. These can be stopped or started by the miller at any time while the Bolt is in operation—either one set, two, or all, as circumstances may require. These, every practical miller knows, after having used them, to be indispensable to counteract the extremes of damp and dry, or cold and exceedingly warm weather. Some millers utterly condemn the use of knockers on bolts, and, in reference to those commonly in use, we will agree with them in this. The difficulty lies in the fact that commonly they are so arranged that the miller is obliged to use them at all times. In free bolting weather, he not only wants to stop the percussion apparatus, but also to have all the safeguards against too free bolting at his command. With this apparatus and proper grinding no clogging of the Bolt will ever be noticed. By the use of this apparatus we are enabled to use finer cloth than without it, and at all times bolt even and obtain better yields. This tried and valuable improvement has been secured by Letters-Patent.

These Mills and Bolts, or either of them separately are constantly being attached to old and new mills, warehouses and places where steam and water power can be had or used. We use on these Bolts Dufour & Co.’s celebrated Dutch Anchor brand of Bolting Cloth made up in best manner with 2½ inch strips of heavy ticking to come in contact with the ribs of reel.

Some parties erroneously entertain the idea that a portable mill is a temporary affair. They obtain this idea from the word portable. This word, applied to a mill, means only that the machinery is built in such a manner at the factory as to permit of its being shipped the same as any other machinery. Our portable mill has all the qualities for doing good work, and all the durability, that any old style mill has. It further has the advantage of enabling a man to put up his mill without near so much delay and expense as is required in the old style. In every instance where a portable mill has failed to do its work properly or to be durable, it has not been because it was a portable mill, but because it was not constructed on good well-tried principles, or of good material, or the fault may have been because it was not set up as it should be, or had not been properly managed after it was set up.

Our Mills and Bolts are fitted up and put together ready to run, before shipment, then properly arranged for shipping, and delivered on board the cars at the proper depot here, and a through rate of freight contracted in the shipping receipt.


COMPLETE PORTABLE GRINDING AND BOLTING FLOURING MILLS.

The cuts, Figs. 1, 2, 3 and 4, are intended to show the different arrangements in buildings and are made by us of the following sizes of stones: 30, 36 and 42 inches diameter of upper-runners, and 26, 30 and 36 inch of the under-runner kind, with the bolts described fully elsewhere, of ample capacity and to meet the special demands of a custom mill, capable of making flour that will bear inspection in any market, at the same time good yields, and are as economical in the use of power as any mill in the United States. Drawings and directions to set up sent with each mill when ordered. It betters the arrangement to place the husk frame 20 inches below the floor; the discharge spout and hoppers all come at a convenient height for the miller to see into the hopper and operate the mill without stooping. In Figs. 1 and 3 they are shown thus. We advise making a platform in the rear of the mills over the belts. The stones and bolt-chest can be placed on same floor, as Fig. 1, or the bolt above as the situation requires. They will grind and bolt from six to fifteen bushels per hour according to size, and can be put in operation in a short time, and are no more liable to get out of repair than the best mill in use.

Those having their power all ready, should give us the dimensions of it and kind, to enable us to give correct information as to size of mill best adapted to it, &c., &c.

COMBINED MILL HUSK.

In cases where there is or can be a basement under the grinding floor, we advise lengthening out the husk posts sufficiently to throw the gearing or belts entirely below the floor. When this is done the husks of the two or more run of burrs are combined into one, making it very solid. This style of mill, where there is room under the grinding floor for it, is the best arrangement possible.

A husk of this kind has all the firmness and solidity of the usual style of frame husk, and yet it is not so bulky and cumbersome. Heavy joint bolts being used entirely, instead of pins, it can readily be tightened up, should any part become slack. These joint bolts bring the timbers harder and more firmly against the shoulders than it is possible for pins or keys; hence its exceeding firmness. Mills put up by us in this style cost the purchaser less money than it is possible for him to buy the burrs, spindles, steps, lighter screws, steps, feed rigging, etc., complete, and then get his timber, hire hands, and build it himself. After he finishes his husk, he will find, in addition to its costing him more than if we should furnish it, he has not nearly as neat a husk, nor one that looks like a finished piece of machinery. The entire timbers in our Combined Husks are dressed and varnished. While it is together in our shop, before taking apart for shipment, every piece is so marked as to show plainly its place in putting up when it arrives at the mill. Customers purchasing these husks, etc., complete, avoid the delay in starting their mills that is necessarily connected with this when all is made at the mill. At the mill, everything has to be done at a decided disadvantage over doing it at a shop where there are tools and machinery especially adapted for the work, and hands that are thoroughly accustomed to doing it.

This style of Mill, with pulleys on the spindles, driven from an upright shaft by belts with tightening pulleys on the slack side, makes the most convenient, and at the same time, as durable and efficient a mill as can be built. With this arrangement, any burr or burrs can be stopped or started at pleasure, without disturbing the others. Where any changing of burrs has to be done, as is the case in custom mills, this is an important item, both for convenience and economy. It saves the time that would be lost in stopping the entire machinery of the mill, shifting the gearing, and again starting, which will always amount to several minutes, by the time the burrs are again properly grinding. And, further, belts do away with all liability to that jar and chatter that always more or less accompanies gearing not kept in proper condition in every respect, which is very seldom done. The belt gives to the burr a very even, steady motion. Our experience is that these belt mills are as easily and more accurately kept in tram than geared mills with any kind of gearing. This method of driving burrs is not only desirable for custom mills, but is also well adapted for merchant mills. We think no better or more satisfactory arrangement for driving either custom or merchant burrs than this, is in use, and we have had experience with all methods. We have over one hundred of this style of mills running, driven by belts in this manner, and they are giving the most entire satisfaction. Most of them are run by parties that have used various other methods of driving their burrs. These all give this style a most decided preference over any other method of driving. The cost is about the same as gearing. We can now give parties interested, references to mills of this same kind in most any of the middle and western States. Of course we do not advocate this plan of driving burrs, nor this style of husk for every case. There are a great many places where there is not the necessary basement room, and parties do not wish to go to any more expense than the usual short husk portable mill, and some situations would require a geared mill all rigged and fitted up in the best manner.

In the engraving, Fig. 7, is shown one of these husks with two upper and one under runner mill; the frame is not shown as heavy as we use for 42 inch and 4 feet stones; one of the lower belts is shown, the others in dotted lines. The shelving for supporting the belt when the tightening pulley is thrown back is not shown. Our adjustable tightening frame and hinge is of superior advantage in stopping and starting either one or all the burrs. They are operated by hand wheels from above in a very simple and easy manner not shown in the cut. The precise slant and position of this movable pulley is regulated by an improved hinge having but three castings, a wrought iron rod, and three screw bolts, one of them provided with two hexagon nuts to regulate the position in one direction, while the plate to which the frame is hinged allow it to be adjusted in another required direction. By keeping the pulley in the proper position the belt raises from the shelving and touches nothing but the pulleys when in motion. The excellence of this combined mill arrangement, with the new features, is considered of great advantage, and is highly commended by all of those using them.

DOUBLE REEL BOLT.

Lower part of Elevator and Cooling Conveyor not shown; doors opening to the reels on the opposite side of chest.


DOUBLE REEL BOLT.

Where more bolting surface is required than there is in a single reel bolt, we build them with two reels, in portable chests, and embodying all the advantages and improvements of our single reel portable bolts. We furnish with them the gearing, elevator, etc., complete and neatly finished. They are built in sections for convenience in shipping and handling. We build also three and four reel chests to order. We send with these bolts all that is mentioned as being furnished with the single reel bolts, except we send 48 feet of elevator belt and 36 cups. Will state that while we are willing to furnish all the irons belonging to our bolts at fair rates, with draft and specifications showing how to make them, we advise our customers to have the complete bolt made here and shipped with the other supplies of the mill. The mill and all by so doing gives better satisfaction, besides a great saving in expense. We have sent them South into Georgia; North into Northern Minnesota, and West into Western Kansas and Nebraska. For such long distances we recommend to have them taken apart and boxed as referred to under head of “Single Reel Bolt.”

We make them of the following length of reel shafts, 16, 18, 20 and 22 feet; the chest and frame supporting the gearing at head makes each bolt measure 2½ feet longer. They are all about 8 feet 7 inches high to top of elevator.


Grinding and Flouring, and Capacity.

All should know that the most important item in converting wheat into flour, is the Grinding Mill. Grain cannot be properly floured without burrs of good quality, dressed expressly for the purpose. Although a Miller of not much experience may sometimes make a pretty fair article of flour, yet those having the most experience will always find something to learn on this subject. It is best that the skill of an expert Miller be employed to prepare the face and furrows of the burrs and put them in order for grinding. Our mills, when properly dressed and in order, make a quality and yield of flour unsurpassed by any other mill, as the letters from our customers testify. Nevertheless, some of our mills, run and managed by unskillful hands, are making a tolerable article of flour, without much care to dress the burrs and keep in order, and sometimes are run a long time without any dressing. In grinding wheat, the burrs should be adjusted with precision, and should always occupy the attention of the Miller. In grinding grists, some damp and others dry, and of different qualities of wheat, the stones require close attention. The runner should be raised slightly for damp wheat; if not, the burrs are liable to heat the chop, and clog their grinding surfaces. If allowed to run too close on dry wheat, the bran will be cut and the flour made dark. These are common difficulties, but can be avoided by a careful miller who wants to make a fine article of merchantable flour, and good yield. The several qualities of wheat and its conditions, as well as the particular quality of flour required to meet the demand of any particular market, must be observed and understood in order to determine the best mode of grinding.

An Important Item.—Be sure to keep the furrows sufficiently deep, and especially so for corn, and see under heads of “Setting up and Starting” and “Keeping in Order.” Burrs are apt to throw out unground grain if run too slow, when, if the speed is increased, this difficulty is obviated.

Grinding Corn.—The dress is not that required for wheat. For corn, let every part of the surface be sharp, and the furrows cut deep; thus, with a high speed, the meal will not be heated. When the meal is ground hot, the stones are dull or the furrows not deep enough. It requires much more power to grind with dull stones or shallow furrows. Every stroke with a sharp pick makes a great number of sharp cutting edges upon French Burr, which cut easy, like a sharp tool in wood.

Be careful to keep the burrs well balanced and in tram. See observations elsewhere under this head.

In reference to the capacity of our mill we will give our opinions from the practical knowledge and experience we have had with them. Having a number of water and steam mills of our entire make and completion near our works and in our city, some having been built with special reference to having all first-class, our opportunities have been good near at hand for constant improvement. While much depends upon the power and condition of grain, our mills are made of the kind of burr stone, carefully selected, with furrows drafted and shaped in the most approved style, that the greatest attainable results may be accomplished. Under favorable circumstances our three feet mills have ground to make good flour and yields 14 bushels per hour, which, when in moderate condition as to sharpness, would do but 8 or 10 bushels. Our under-runner mills average a greater capacity than the upper-runner kind.

The amount our mills and mill stones will grind to do it well, is as great as that successfully obtained by any mill in existence, and always has been entirely satisfactory, oftentimes astonishing old and experienced millers. On one occasion two of our three feet upper-runner mills with two single reel bolts have made 100 bbls. of merchantable flour in 24 hours. With the larger sizes we could point to proportionally greater results.

Our three and three and a half feet mills are often found grinding faster than the four feet sizes of the old style of mills, at the same time doing as good and better work. These are facts, and the reasons why are simply because the stones are run at a greater speed, while the furrows are shaped to avoid heating, and properly drafted to distribute the grain evenly over the grinding surfaces. Also, much is owing to a good selection of the burr stock of which the stones are made. We conclude this subject by reference to some who have given us their views, carefully expressed in writing, and here published for the benefit of all those interested in milling.


Keeping in Order.

The face of the bed stone must be kept level and the spindle in perfect tram with it. To tram, take off the hoop and runner stone, and if a Pulley Mill, put on the belt the same as when grinding; then place on the spindle a wooden arm with a hole in one end to fit tight on the upper end of spindle, so that it will traverse the face of the bed stone, having before made a small hole through the projecting end to receive a quill or piece of whale-bone to trace the surface of the bed-stone about two inches in from its skirt. On turning the spindle, it can now be readily seen which way the step is to be moved in order to throw the spindle in tram; if it is properly in tram, the quill will traverse the bed-stone evenly around its face. To tram our geared mills, the toe of the spindle must not be moved out of line with the shaft holding the driving gear wheel; the proper way is to tram it in the bush, which is provided with suitable keys. However, when the toe of the spindle or step is required to be moved length-ways of this shaft, no bad results will follow, provided the cogs are all the time in proper depth—even on their back or large end, and not too deep in gear. The spindles of our mills are not apt to get out of tram, but in all mills they should be closely watched and frequently tried in this particular. When the spindle is in perfect tram, and the runner in balance, the burrs will not wear out of face, but the reverse, they will naturally wear in face. The followers should not be forced too hard against the spindle by the wedges in the iron bush, as it will make the spindle heat.

The space under the leather, on top of the bush, should be well supplied with tallow rolled up in a woolen cloth and laid immediately around the spindle. The oil cup in the bush should be supplied with good sperm or lard oil every time the burrs are taken up. Place some candle-wick in this cup, with one end against (not around) the spindle. This keeps the spindle supplied with a continual flow of oil in addition to the tallow. Oil the spindle step with good sperm or lard oil, clean out once a month, and keep out dirt.

In geared mills, pay particular attention to the adjustment of the gear wheels. If they are too deep or not deep enough in gear, they will not run so smoothly and will cut out. As the wooden cogs wear, in time a shoulder will be formed on them by the iron cogs in the pinion. In order to obviate the tremble or rough running that this shoulder would cause, it should be trimmed off from time to time. Grease the cogs with tallow, and see observations on keeping stones in order, under head of “Setting up and Starting.”

We request as a favor of any of those using our machinery, mills, bolts, &c., to inform us if they are not working satisfactorily; in such a case, state plainly as you can in what particular, as we will take pleasure in correcting the defect or giving advice concerning it. Some of our mills and mill stones that have been used constantly for 8 to 12 years may require some changes, such as re-setting the irons, improving the dress, &c., that would make them as good as new; when written to or interviewed on the subject, will state to the best of our ability what should be done.


In Ordering, or when a Correct estimate of Cost is Wanted,

It will be quite a help both to our customers and to ourselves to observe the points mentioned below. A plain statement of the situation and what is wanted, together with a rough sketch will often save much delay and trouble.

1st. Give location of Mill, i. e., its relation to road, railway, and power; where it is most convenient to receive grist work and where merchant grain.

2d. State size of mill house; height of stories from floor to floor; pitch of roof, and which way comb of house runs; which way the joist and timbers of the mill run, and their size.

3d. If there is a basement under the grinding floor, and how high.

4th. If water power is to be used, state size and kind of water wheel and its speed. If a turbine wheel, give height of head, which way wheel runs, and location of mill-house.

5th. If the power has not been improved, state the fall that can be obtained, and give the amount of water in depth and width running over a weir. See “Measurement of Water in a Stream.”

6th. If the power used is steam, give the diameter of cylinder and length of stroke of engine; number of revolutions per minute made by engine; diameter and width of face of band wheel on engine; which way the engine runs—whether top of band wheel runs to or from the mills.

7th. Make a sketch showing the location of engine bed plate and shaft to the mills.

8th. State whether the mills are wanted to run with or against the sun. We build them to run with the sun unless otherwise ordered.

9th. Name the place to which the machinery is to be shipped and, if thought best, by what route. It often happens that we can judge best the way to ship. Also, your name and post office plainly and in full.

We deliver our goods on board cars at the proper depot here, free of charge, and take a contracted through receipt with rate of freight stated in it, and send to the purchaser, thus guarding our customers against over-charges or high rates of freight. For 5 per cent. added to our prices, we will pre-pay freight on one half and full car load lots to Buffalo, Philadelphia, Baltimore, St. Louis, Quincy, Rock Island and Memphis. 3 per cent. will cover it to Chicago, Pittsburgh, Toledo, Louisville and Evansville. On boat or cars at any depot in Cincinnati we will pre-pay freight at 10 cents per 100 lbs., (weights are given on list.) Great care is taken to inclose such parts of our supplies and mills when necessary in strong boxes, iron bound at the corners, so that they can be conveyed safely to any part of the world.


Setting up and Starting.

We have often found it to the advantage of our customers to have one of our own men assist in setting up and starting. Their experience and familiarity with our machinery enables them to expedite the setting up. They are employed on this important part of our work constantly. Our charges for their services are reasonable. In some of the far western States we have skilled mill-wrights for this purpose, thus saving time and expense to the purchaser. From drafts and explanations we send (when requested to do so) with our mill work and mills, mill-wrights can generally succeed in giving good satisfaction.

The burrs of all our mills are faced true and furrowed, but do not have as smooth a grinding or flouring face as is necessary for flouring wheat. A few days work by the miller with pick and rub stone is of great advantage. To do this important work correctly requires one skilled in the use of the red staff, with a good true iron proof staff close at hand. We are sorry to be compelled to say that the millers are few that know how to correctly handle the red staff on the face of a mill stone. It is a difficult matter to explain the manner of doing it without a personal interview and the implements in readiness. However, we are ready to give on this point of great importance all the information we can by sketches and writing.

View of Eureka Smutter.Sectional View.
(See following page.)

This Cut Represents either size Machine driven from the Top when so required.

Some of the Reasons why the Eureka Should be used in preference to any other Smut and Separating Machine now offered for Sale:

1st. The scourer used in the Eureka is constructed of the best imported cast sheet steel, manufactured and rolled expressly for this purpose. The scouring is done on an entire smooth surface, and by direct action on the grain, thoroughly scours and polishes the berry without waste, and at the same time retains its scouring qualities until the scouring case is entirely worn out. As the beaters or fan blades of the revolving scouring cylinders are chilled cast-iron, they will last for years without perceptible wear, and when the steel case is worn out by severe friction of the grain, can be replaced at a small expense. All machines are so strongly and permanently built, and the revolving cylinder so perfectly balanced, that they will, with ordinary care, last for years, with the small additional expense of renewing the scouring case, once in from three to five or eight years, as the case may be.

2d. For its entire reliability in cleaning the worst samples of smutty wheat; the preliminary or first separator is attached to all the No. 0, 1, 2 and 3 Ordinary sizes, which removes smut balls, dust, chaff, chess or cheat, and light and worthless grains, before the wheat goes to the scourer. As the scourer is thoroughly ventilated, supplied by air at the bottom, and discharging the smut and dust loosened from the grain during the process of scouring, through the perforations of the scouring case, and the fan at the same time drawing a strong current of air through the revolving cylinder, there is no possibility of the grain coming in contact with smut and dust during the process of scouring. Most of the so-called close scouring machines that are now being urged upon millers are destitute of this important principle, and hence worthless.

3d. The Eureka, so far as we know, is the only machine that has a perfect shoe attachment, and where the machine is the best known is always invariably ordered. It requires little or no attention, being driven by a belt from main shaft of the machine and a spring pitman; it makes no noise, and with the improved double screen, takes out more headings, straw joints, rat filth, corn and oats, than can possibly be taken out with the rolling screen, while the cockle screen takes out cockle, sand, etc., and we earnestly advise all persons ordering the No. 0, 1 or 2 machines, to order the shoe in all cases. It is now very seldom that we have an order for either of the three sized machines above referred to without the shoe, and in nine cases out of ten when machines are so ordered, the shoe is afterwards ordered, thereby causing extra expense and trouble.

The last reason we shall give is that this is, in all respects, the best wheat cleaning machine in the world; this to millers is an important consideration, and cannot well be overlooked.


In Ordering Smut Machines,

First, decide the size or number of machine wanted, and in deciding this, it will be well to remember that the machines will do all claimed for them. If a machine is wanted to clean twenty-five bushels per hour, a No. 1 machine, run to the motion designed for it, will do it much better than a No. 2, and either size machine run to the motion and fed to the full capacity, will do much better work than if run at a less motion and with a less feed. Some have thought that if a No. 3 machine, for instance, will clean one hundred bushels per hour well, that it will clean sixty bushels better. This is a mistake.

Warranty.

All machines are warranted to be built of the very best material and perfect in all their parts, and any defect in the material or construction will be made good to the purchaser without charge; and further, to give entire satisfaction, when put up and run according to directions attached to all machines.

Terms.

When the cash is remitted with the order, or within thirty days from date of shipment, a discount of five per cent. will be allowed, or list price at the end of ninety days. If longer time is required, approved notes on interest after ninety days from date of shipment, payable in bank, will be required.

DUSTLESS OAT SEPARATOR AND ZIGZAG.
With two or four Wheat Riddles and Cockle Riddle.

Patented April 9, 1861; Re-issued, April 19, 1871.

This Machine is named “Dustless Separator,” because the Dust is separated from the wheat, conveyed out of the mill, and deposited in a dust room, before the grain passes to the riddles; the wheat and screenings are left free from dust.

Its operation is as follows:—The grain enters the Machine at the hopper, which is shown, where it receives the first blast; then passes through two to four wheat riddles in succession, and over a cockle riddle into the second blast. The riddles deposit oats, sticks, weeds, ergot, rat-balls, etc., in suitable spouts; the heavy screenings fall into a hopper and are spouted off. This Machine has none but suction blasts, and is offered to the milling community as a first-class Separator.

FLOUR PACKER.


FLOUR PACKERS.

Mattison’, Taggart’ and other well known Packers, ready for shipment on short notice. For some situations one kind may suit better than another, and when we know the purpose it is designed for can advise which would suit best. The advantages of them are, that they are ready for use when shipped by merely setting up and attaching power, and suited to a variety of work in the packing line. The Mattison kind will pack in barrels or paper sacks of different sizes.

When a cheap Packer is wanted we have the Portable Conical Roller Flour Packer.

Capacity, 3 barrels per hour—12 to 18 revolutions per minute. Weight, 250 pounds.


HUNTLEY & HOLCOMB’ EXCELSIOR BRAN DUSTER.

ADJUSTABLE WHILE RUNNING.

This cut shows the Duster as completed, with shoe attached, with part of the outer case and part of the wire gauze cylinder removed, to show the interior of the Machine. The lower section of the outside case containing the spouts never being removed after once set up in the mill; the shoe can be turned to any position required, by turning the top plate with it which can be done by slacking the tie rods that bind all together.

The manufacturers have recently improved their already celebrated and widely-known Machine. They say in their latest circular, “We have had thirteen years experience on Bran Dusters, and nearly eleven years of the time on our present Machine, and think we understand the wants of Millers in this line perfectly. Our aim has been to make as perfect a Duster as could be made, and think we now have a perfect one to offer the milling public.

“Ours is a vertical Machine and so constructed that it can be run either with or against the sun, as may be required.

“The Wire-cloth Cylinder is made in halves, and can be unbolted and taken out one-half at a time, and can be turned around for examination on all sides while the Machine is running.

“We put on all sizes, a shoe to throw off dough balls or any foreign substance that would injure the wire-cloth, making it a perfect Machine without any other device than the Machine itself.

“We have had Machines running side by side with all the other kinds of Dusters and have always beaten them in quantity and quality of flour, and are ready at any time to put one to a test with any other Machine.

“This Machine has a Revolving Cylinder of pure Bristol Brushes and has nothing but the Brush Cylinder to drive, making it run extremely light, requiring less than one-half of one-horse power to drive the largest sized Machines.

“There are now over seven hundred of them running, and as far as we know all are giving perfect satisfaction, and we defy any man to show us where one has been superseded by any other Machine; further, we will say that we have put our Machine in place of several other kinds, and have given satisfaction in all cases where others have failed. We find in other Circulars statements that their Machines will make ten per cent. of flour; we say this is exaggerated; we have made five and one-fourth per cent., and say this is more than any other Duster can do with a fair test. We do not make statements that are exaggerated, but only such as we are willing to guarantee.

“For cleaning Cracked Wheat, Pearl Barley, and all this class of material, there is no better Machine, and we can give the best of testimonials of their work on this kind of material.”

This cut is a sectional view of the Machine showing the entire construction, except the Shoe, which will accompany all of the Machines. The Flour and Bran Spouts can be turned to any direction required, independently, to adjust them to any location in a mill.

FRENCH BURR FARM AND PLANTATION MILL.

Patented August 1st, 1871.

This mill has been built by us and in use for a number of years, and in all cases has proven itself worthy of the reputation it has obtained.

The changes made within the last two years make it the best investment of money that can be made by any one wanting a cheap mill. It is complete in itself, not requiring any hangers, &c., to set it in operation, and can be put to work without an experienced mechanic. In its structure we have not been sparing in the material necessary to make every part strong and durable. They will bear to be continually used with a strong power without any part yielding in the least. The objections to most mills of this class is caused by their being put up in soft wood frames, and castings of frail dimensions, the consequence being that the spindle and important parts soon get out of place. To those having any kind of light power the smaller sizes are well adapted, and in every situation where they have been properly placed their satisfactory working has been exemplified and will be guaranteed by us. It will grind middlings or minerals, all kinds of feed and make good family meal.

The above cut is a fair representation of the mill; it is simple, and has less parts than any other mill in the market. It has a horizontal steel spindle running in anti-friction metal bearings, and a steel seat at its end to receive the pressure of the burrs in grinding.

The runner is placed in an iron back and rigidly keyed to the spindle. The bed stone is so arranged as to be self-adjusting. The mill cannot get out of tram, since when left at liberty it will adjust itself into perfect tram. The bed stone is held up to its place in grinding by a stiff rubber spring, so as to enable it to yield in case any hard substance enters between the burrs, thus obviating the danger of breakage, and yet not permitting the stones to yield or press apart in grinding ordinary substances. The spindle being horizontal this mill can be driven directly from an engine, horse-power, or line-shaft. One great item of superiority is that a strong or light power may be used and the mill will grind in proportion, and will do good work at the same time. Every mill warranted.

CORN AND COB CRUSHER, AND GRINDER.

Chill Hardened Corn and Cob Cracker, Bone and Bark Mill.

They are made of the best chill hardened iron, well fitted, and are undoubtedly the best thing now made for the purpose, outwearing, in some instances, three of the common kind. They can be set up in any kind of a building, sometimes to the side on two strong brackets, or on any suitable frame. It has a tight bottom and side spout, the power can be applied at either the upper or lower end of spindles, or it can be run with horizontal shaft by belt and gear. Speed from 160 to 175 revolutions per minute. Capacity from 30 to 60 bushels corn per hour, depending upon speed, power, and condition of corn.

They can be furnished complete with a large iron hopper, and set on a frame, with gearing, shaft, tight and loose pulley attached if so ordered.


PATENT CENTRIFUGAL CORN SHELLER AND CLEANER.

Clean the Shelled Corn Perfectly. Shell each Ear Separately. Require no Self-Feeders. They shell Clean. Do not Break the Cobs. Do not waste the Corn.

The above is a cut of our No. 1 Centrifugal Corn Sheller and Cleaner. The operation of this Sheller is as follows:

The ears of corn are shoveled direct into the Sheller, and fall on to the center of a flat Perforated Shelling Wheel where they are thrown by centrifugal force towards the outside, but being caught by guides held down by a spring plate working between them are, “by the action of the wheel,” made to revolve, the corn shelled off, and the cobs forced off the wheel endwise and without being broken, fall on the Cob Carrier, and are carried away from the Sheller; while the shelled corn passes through the Cob Carrier to the Shaker, and thence to the Conveyor, into the Elevator, when it is raised into bags, wagons or cars.

In cleaning the shelled corn they cannot be excelled. In addition to our Cob Carrier, we have a Shaker with a sieve made of perforated iron, which is preferable to a wire sieve, as no silks will adhere to and clog it. While falling on and passing through the Shaker, the grain is subjected to a strong blast from the fan, which thoroughly cleans it of all chaff, pieces of cobs, dirt, etc., leaving it in prime order for market.

Our No. 1 will shell and clean from 700 to 1200 bushels of shelled corn per day, with two to four horse power.

THE VETERAN.

Two-Hole Separating Sheller.

For these we have a steady demand at all times of the year, and send them to all parts of the country.

They do not operate in the loose rattling way of ordinary Two-Hole Hand Shellers, got up to sell cheap, but work as closely and effectively as any of the most effective Power Shellers; and no hand sheller has been so much relied on for regular business as the Veteran.

The frames are made of the best and most thoroughly seasoned hard wood, framed as closely as the joints can be driven together, and are “solid as rock.” The shafts, shelling wheels, boxes, journals, etc., are on the same scale of strength and close fitting.

They have the revolving wire cob carrier for separating the cobs from the shelled corn, and when so ordered, they can be fitted with a band wheel for connecting with power, and a feed table, as shown in the cut, thus making a small and convenient power sheller.

THE CADET.

Single or One-Hole Hand Sheller.

It is strong framed: the frame being of the best seasoned hard wood, capped with iron. Has the same character of shelling wheels as the power shellers, bored true and fitted on shafts which are turned full length and held in strong and durable boxes; has a fine adjustment of spout irons and springs.

It separates the Cobs from the Shelled Corn, and has a Fan for Cleaning the Grain.
