The location of a mill has a great deal to do with the results attained. Having had charge of the erection of a large number of these mills for power purposes, I will refer to a few of them in different States, giving the actual results accomplished, and leaving you to form your own opinion as to the power developed.
In 1877 a 25-foot diameter mill was erected at Dover, Kansas, a few miles southwest of Topeka. It was built to do custom flour and feed grinding, also corn shelling, and is in successful operation at the present time. We have letters frequently from the owner; one of recent date states that it has stood all of the "Kansas zephyrs," never having been damaged as yet. On an average it shells and grinds from 6 to 10 bushels of corn per hour, and runs a 14 inch burr stone, grinding wheat at the same time. During strong winds it has shelled and ground as high as 30 bushels of corn per hour. Plate 2 is from a photograph of this mill and building as it stands. One bevel pinion is all the repairs this mill has required.
In the spring of 1880 there was erected a 25-foot diameter mill at Harvard, Clay County, Neb. After this mill had been running nineteen months, we received the following report from the owner:
"During the nineteen months we have been running the wind mill, it has cost us nothing for repairs. We run it with a two-hole corn sheller, a set of 16-inch burr stones, and an elevator. We grind all kinds of feed, also corn meal and Graham flour. We have ground 8,340 bushels, and would have ground much more if corn had not been a very poor crop here for the past two seasons; besides, we have our farm to attend to, and cannot keep it running all the time that we have wind. We have not run a full day at any time, but have ground 125 bushels in a day. When the burr is in good shape we can grind 20 bushels an hour, and shell at the same time in the average winds that we have. The mill has withstood storms without number, even one that blew down a house near it, and another that blew down many smaller mills. It is one of the best investments any one can make."
The writer saw this mill about sixty days ago, and it is in good shape, and doing the work as stated. The only repairs that it has required during four years was one bevel pinion put on this spring.
The owner of a 16-foot diameter mill, erected at Blue Springs. Neb., says that "with a fair wind it grinds easily 15 bushels of corn per hour with a No. 3 grinder, also runs a corn-sheller and pump at the same time, and that it works smoothly and is entirely self-regulating."
The No. 3 grinder referred to has chilled iron burrs, and requires from 3 to 4 horse-power to grind 15 bushels of corn per hour. Of one of these 16-foot mills that has been running since 1875 in Northern Illinois, the owner writes: "In windy days I saw cord-wood as fast as the wood can be handled, doing more work than I used to accomplish with five horses."
The owner of one of these mills, 20 feet in diameter, running in the southwestern part of this State, writes that he has a corn-sheller and two iron grinding mills with 8-inch burrs attached to it; also a bolting device; that this mill is more profitable to him than 80 acres of good corn land, and that it is easily handled and has never been out of order. The following report on one of these 16-foot mills, running in northern Illinois, may be of interest: This mill stands between the house and barn. A connection is made to a pump in a well-house 25 feet distant, and is also arranged to operate a churn and washing machine. By means of sheaves and wire cable, power is transmitted to a circular saw 35 feet distant. In this same manner power is transmitted to the barn 200 feet distant, where connection is made to a thrasher, corn-sheller, feed-cutter, and fanning-mill. The corn-sheller is a three horse-power, with fan and sacker attached. Three hundred bushels per day has been shelled, cleaned, and sacked. The thrashing machine is a two horsepower with vibrating attachment for separating straw from grain. One man has thrashed 300 bushels of oats per day, and on windy days says the mill would run a thrasher of double this capacity. The saw used is 18 inches diameter, and on windy days saws as much wood as can be done by six horses working on a sweep power. The owner furnishes the following approximate cost of mill with the machinery attached and now in use on his place:
1 16-foot power wind mill, shafting, and tower. $385
1 Two horse thrasher. 70
1 Three horse sheller. 38
1 Feed grinder. 50
1 18-inch saw, frame and arbor. 40
1 Fanning mill. 25
1 Force pump. 27
1 Churn. 5
1 Washing machine. 15
Belting, cables, and pulleys. 45
