Baltimore Hats, Past and Present

by William Tufts Brigham

BLOWING ENGINE.

The "body," or "foundation," of a good beaver hat is generally made of eight parts rabbit's fur, three parts Saxony wool, and one part of llama, vicunia, or "red" wool. A sufficient quantity of these for one hat (about two and a half ounces) is weighed out and placed in the hands of the "bower." On entering the "bowing-room" a peculiar twanging noise indicates to the visitor that a stretched cord is in rapid vibration, and the management of this cord by the workman is seen to be one of the many operations in hatting wherein success depends exclusively on skillful manipulation. A bench extends along the front of the room beneath a range of windows, and each "bower" has a little compartment appropriated to himself. The bow is an ashen staff from five to seven feet in length, having a strong cord of catgut stretched over bridges at the two ends. The bow is suspended in the middle by a string from the ceiling, whereby it hangs nearly on a level with the work-bench, and the workman thus proceeds: The wool and coarse fur, first separately and afterwards together, are laid on the bench, and the bower, grasping the staff of the bow with his left hand and plucking the cord with his right hand by means of a small piece of wood, causes the cord to vibrate rapidly against the fur and wool. By repeating this process for a certain time, all the original clots or assemblages of filaments are perfectly opened and dilated, and the fibers, flying upwards when struck, are, by the dexterity of the workman, made to fall in nearly equal thickness on the bench, presenting a very light and soft layer of material. Simple as this operation appears to a stranger, years of practice are required for the attainment of proficiency in it.

The bowed materials for one hat are divided into two portions, each of which is separately pressed with a light wicker frame; the light mass of fluffy fur, after being pressed with the frame, is covered with a wet cloth, over which is placed a piece of oil-cloth or leather called a "hardening skin," until, by the pressure of the hands backwards and forwards all over the skin, the fibers are brought closer together, the points of contact multiplied, the serrations made to link together, and a slightly coherent fabric formed. These two halves, or "batts," are then formed into a hollow cap by a singular contrivance. One of the "batts," nearly triangular in shape, and measuring about half a yard in each direction, being laid flat, a triangular piece of paper, smaller in size than the batt, is laid upon it, and the edges of the batt, being folded over the paper, meet at the upper surface, and thus form a complete envelope to the paper. The two meeting edges are soon made to combine by gentle pressure and friction, and another "batt" is laid on the other in a similar way, but having the meeting edges on the opposite side of the paper. The double layer, with the enclosed paper, are then folded up in a damp cloth and worked by hand; the workman pressing and bending, rolling and unrolling, until the fibers of the inner layer are incorporated with those of the outer. It is evident that were there not a piece of paper interposed, the whole of the fibers would be worked together into a mass by the opposite sides felting together, but the paper maintains a vacancy within, and when withdrawn at the edge which is to form the opening of the cap, it leaves the felted material in such a form as to constitute, when stretched open, a hollow cone.

The "battery" is a large kettle or boiler open at the top, having a fire beneath it, and eight planks ascending obliquely from the margin, so as to form a sort of octagonal work-bench, five or six feet in diameter, at which eight men may work; the planks are made of lead near the kettle, and of mahogany at the outer part, and at each plank a workman operates on a conical cap until the process of felting or "planking" is completed. The "battery" contains hot water slightly acidulated with sulphuric acid. The cap is dipped into the hot liquor, laid on one of the planks, and subjected to a long felting process; it is rolled and unrolled, twisted, pressed, and rubbed with a piece of leather or wood tied to the workman's hand, and rolled with a rolling-pin. From time to time the cap is examined, to ascertain whether the thickness is sufficient in every part, and if any defective places appear, they are wet with a brush dipped in the hot liquor, and a few additional fibers are worked in. Considerable skill is required in order to preserve such an additional thickness of material at one part as shall suffice for the brim of the hat. When this felting process has been continued about two hours, it is found that the heat, moisture, pressure and friction have reduced the cap to one-half its former dimensions, the thickness being increased in a proportionate degree, assuming a conical shape.

The "cap" is then taken to the "water-proofing" or "stiffening" room, where the odor of gum, resins and spirits gives some intimation of the materials employed. Gum-lac, gum-sandrach, gum-mastic, resin, frankincense, copal, caoutchouc, spirits of wine and spirits of turpentine, are the ingredients (all of a very inflammable nature) of which the water-proofing is made. This is laid on the cap by means of a brush, and the workman exercises his skill in regulating the quantity at different parts, since the strength of the future brim and crown depends much on this process.

After another heating in a hot room, called "stoving," by which the spirit is evaporated, the exterior of the cap is scoured with a weak alkali, to remove a portion of the gummy coating, and thereby enable the beaver fur with which it is to be "napped" or "coated," to adhere.

A layer of beaver fur is spread, and, by means of the "hardening stick," is pressed and worked into a very delicate and light felt, just coherent enough to hold together. This layer, which is called a "ruffing" or "roughing," is a little larger than the cap-body, and to unite the two, another visit to the "battery" is necessary. The cap being softened by immersion in the hot liquor, the "ruffing" is laid on it, and patted down with a wet brush, a narrow strip of beaver being laid round the inside of the cap to form the underside of the future brim. The beavered cap is then wrapped in a woolen cloth, immersed frequently in the hot liquor, and rolled on the plank for the space of two hours. The effect of this rubbing and rolling is very curious, and may be illustrated in a simple manner: if a few fibers of beaver fur be laid on a piece of broadcloth, covered with tissue paper, and rubbed gently with the finger, they will penetrate through the cloth and appear on the opposite side. So, likewise, in the process of "ruffing," each fiber is set in motion from root to point, and enters the substance of the felt cap. The hairs proceed in a pretty straight course, and just enter the felt, with the substance of which they form an intimate union. But if the rolling and pressing were continued too long, the hairs would actually pass through the felt, and be seen on the inside instead of the outside of the cap; the workman therefore exercises his judgment in continuing the process only so long as is sufficient to secure the hairs in the felt firm enough to bear the action of the hat-brush in after-days.

At length the cap is to assume somewhat the shape of a hat, before it finally leaves the "battery." The workman first turns up the edge of the cap to the depth of about an inch and a half; and then draws the peak of the cap back through the centre or axis so far as not to take out the first fold, but to produce an inner fold of the same depth. The point being turned back again, produces a third fold, and thus the workman proceeds, till the whole hat has acquired the appearance of a flattish circular piece, consisting of a number of concentric folds or rings, with the peak in the centre. This is laid on the "plank," where the workman, keeping the substance hot and wet, pulls, presses and rubs the centre until he has formed a smooth flat portion equal to the intended crown of the hat. He then takes a cylindrical block, on the flat end of which he applies the flattened central portion of the felt, and by holding a string down the curved sides of the block, he causes the surrounding portion of the felt to assume the figure of the block. The part which is to form the brim now appears a puckered appendage round the edge of the hat; but this puckered edge is soon brought to a tolerably flat shape by pulling and pressing.

The workman then raises and opens the nap of the hat by means of a peculiar sort of comb, and then shears the hairs to a regular length. Connoisseurs in these matters are learned as to the respective merits of "short naps" and "long naps," and by the shearer's dexterity these are regulated. The visitor recognizes nothing difficult in this operation, yet years of practice are necessary for the attainment of skill therein, since the workman determines the length of the nap by the peculiar position in which the long, light shears are held. A nap or pile as fine as that of velvet can be produced by this operation.
