ROSVELL NOR'lHIiOP, OF NEW MILFORD, CONNECTICUT.

MACHINE FOR FELTING HAT-BODIES.

Specification of Letters Patent No. 31,732, dated March 19, 1861.

To all whom it may concern.' Be it known that I, RoswELL NoRTHRor, of New Milford, in the county of Litchfield and State of Connecticut, have invent-ed a new and useful Machine for Felting Hat- Bodies and other Articles; and I do hereby declare-that the same is described and represented in the following specification and drawings.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation referring to the drawings in `which the same letters indicate like parts in each of the figures.

Figure 1 is an elevation of one side of the machine. Fig. 2 is a plan or top view.

The nature of my invention and improvements in machines for fulling and felting hat bodies and other articles consists in a cam roller fluted or otherwise working in connection with one or more fluted rollers, so arranged and operated as to alternately press the articles to be fulled or felted more and then less and more and less in alternate succession as long as required.

In the accompanying drawings A, A, are sills to which the standards B, B, are fastened, which standards are connected by the bars C, C, to form a strong frame to which the working parts are fastened or connected.

D, is a shaft arranged to turn in the sides or standards and may be provided with a crank to turn it by hand, or with pulleys or gears to turn it by some other power to operate the machine. The shaft D, carries the small pulley E, with a belt driving the pulley F, and shaft G, which turns in the brackets H, H, fastened to the Sides B, which shaft carries the cam shaped roller I, which acts on the hat bodies to felt them when they are placed between it and the luted rollers J, J, which rollers are provided with shafts fitted to turn in the `levers K, K, shown in the drawings. The levers K, K, may be made in the form shown and connected at their ends by the bars L, and M, forming a frame which is arranged to vibrate on the rod N, which passes through the levers and the sides B.

l?, is a roller arranged in front of the rollers J, J, and provided with journals which turn in the levers J. This roller is shown by dotted lines in Fig. 1, audits use is to prevent the hat bodies from falling from the rollers J, J. To balance the weight of the rollers which turn between the levers,

I hang the weights Q, Q, on them and arrange these weights to traverse by connecting them with the chains or bands R, R, which pass around the rollers S, and T. The journals of these rollers turn in stands .fastened to the levers lc, and the roller S, is provided with a crank S, so that the attendant may turn the roller and traverse the weights, so that the weight of the rollers J, will depress the levers and rollers away from the cani roller I to put the hat bodies to be felted between them, and then turn the crank, so as to move the weights out on the levers and bring the hat bodies to be felted up against the cam roller I. To turn the surface of the rollers J, J about as fast as the surface of the cam roller I, moves, I

fasten the pulley U, to the shaft l), and a pulley V, with two scores in it, to the shaft of one of the rollers J and runa band around the pulley U and by the stud pulleys l/V, W', to the pulley V, to turn one of the rollers J, and a band from the pulley V, to

the pulley X, to turn the other roller J. The stud pulleys W, are arranged to turn on studs in the slide Y, fastened to the side B, and the pulleys are placed in such a position that when the roller is moved up and down by the lever its motion does not materially shorten or lengthen the band that turns the roller. The pins Z, Z, in the sides prevent the levers from vibrating farther than is proper or necessary. The contiguous surfaces of the cam roller I, and the surfaces of the rollers J, J, move in opposite directions at about the same speed so that the articles to be fulled or felted placed between them will be turned, rolled and pressed as long as may be desired. And in order to enable the attendant to separate or close the rollers and apply the pressure to the articles being felted, I connect the racks a, a to the levers 7c, and arrange the shaft b, to turn in the brackets H, wit-h pinions c, c, fastened to theshaft and working into the racks a, so that the attendant by turning the shaft with the crank CZ, can vary the pressure on the articles being rolled and felted between the `roller I, and the rollers J, J.

I have found-this machine to work well when the cam roller turns about sixty times per minute, and the hat bodies after being wet in hot water'are put 4 or 6 together and rolled in a cloth and put between the rollers and rolled from live to seven seconds, then taken out and opened, Wet and put in and I claim-- l rolled again, and this process may be re- The luted cani roller I in Combination peated as long as necessary. with the rollers J J for the purposes set I believe I hafve dfscrbed and representecl forth. my invention or eltino' hat bodies anc T other articles so as to nable any person ROSVVELL BORTHROP skilled in the art to make and use it. I Will itnessesz now state what I desire to secure by Letters JOHN S. TURRILL, Patent. SOLOMON EBOSTWICK.
