placed in the situation marked ff. A B is i UNITED STATES J. BUllllOlVS HYDE, OF NEW YORK, N. Y., ASSIGNEE IMPROVEMENT IN MACHINERY FOR HARDENING BATS IN FELTING.

Sprciliealion forming part of Letters Patent dated December 14,1S40; Reissue No. |99,

,To all whom it may concern Be it known that THOMAS ROBINSON WIL- LIAMs, a citizen of the United States, did invent a certain new and useful improvement in machinery for forming bats in the manu- I facture of felt, being part of the improvements described in the specification of letters granted for improvements in the machinery and proj cess for the manufacture of felt to the said THoMAs toBINsoN WILLIAMS, bearing date the 14th day of December, 1840; and I do hereby declare that the following is a full, clear, and exact description thereof, reference I being had to the accompanying drawings, making part of this specification, in Which- Figure l is a longitudinal vertical section of one of the machines which may be used for the purpose of hardening the bat, and ,L Fig. 2 a plan thereof.

The same letters indicate like parts in both j the lignres.

The said invention consists ,I bats or slivers into cloth by the machinery I and process hereinafter described, the cloth I so formed depending for its strength and; the union of the materials composing it upon the tendency ofthe materials to felt together, I and this is done without the usual auxil-I iaries of spinning or weaving', or of oil or,y oleaginons matter, which is generally re-I I I I I I in forming quired in the ordinary manufacture for assisting the spinning of yarns; but the wool should be merely well washed, picked, and dried, after which it should be teased and scribbled in the usual way. The dry, clean material, as it is thus prepared, is then to be weighed out into quantities for producing any required thickness and width of goods.

This invention relates to the process for I hardening the bat or sliver formed as before described, or otherwise; and it consists in the use of a machinel for this purpose, which is composed of two series or tiers of rollers, (covered with cloth or otherwise,) between which the bat or sliver is passed, the said rollers being provided with a reciprocatingg endwise motion for the purpose of feltingI the bat, and a progressive rotary motion for I the purpose of feeding the bat through.i The roller E, with the bat upon it, is then I the framework ot the machine aby friction ot' contact with the a PATENT OFFICE.

OF T. llt. WILLIAMS.

dated May (i, 1851.

and 1, 2, 3,4, 5, (i, 7, 8, 9, 10, 11, and 12 are rollers, of which there are two sets, placed, in this instance, (although not neeessarily,) directly over each other. These rollers are wrapped around with au elastic cloth, and the lower tier, g, are furnished with an apron as represented at ay a. There are several small pipes connected with a steam-boiler brought up and inserted between the lower rollers and 5 under the aprons, as represented at c ce, eXtend- I ed from side to side of the'apron and finely perforated upon their upper sides, for the purpose f of admitting steam to escape upward for moist- I ening and warming the bat of wool where the felting process called hardening7 is now commenced. The upper tier of hardening-rolln ers receives an alternating motion endwise by a crank or shaft, s, ruiming along its side,

upon-which there are as many cranks or eccentrics, having a short throw of about threeeighths of an inch, and connected with each upper roller by shackle-bars or slide-rods n a. The hardening-rollers receive also a slow progressive Inotion from the main shaft on the other side ofthe machine by suitable gearing, consequently moving the apron beeeam KQ lq DO tween them as well in the direction of the arrow. There are likewise inserted between these rollers and under the apron several heaters, IL h Il h. These heaters are of hollow metal and connected by stop-cocks with the steam-pipes, for the purpose of increasing and regulating the heat applied to the bat and assisting the incipient felt. The bat being placed in the positionff, Fig. 1, and its end being entered between the front rollers of the hardening-machine at x, it is gradually passed through them, Which, with the alternating motion of the upper rollers acting against the resistance offered by thelower ones, (which do not alternate,) aided by the moisture and heat, arrives at the other end of the machine ina consolidated rm state.

Here, at z, it is again wound upon a roller, F, pron a, and when an old bat intended for an end of cloth is finished and wound upon it it is taken away to receive the next operation by repeat ing the same or placing in the fulling-stocks.

Hot water or soap-snds heated by steam III may be thrown onto the bat af'tcr passing` g roller 12, for the purpose of increasing the feltiug.;l process.

In order to produce the finest and best felt, it is Very desirable to allow the elting-rollers to act upon thc material in every possible direction. By the reciprocating motion of this machine we, have seen that this is produced in each direction longitudinally. In this way it may now be run through this machine several times, and for solne descriptions may eren be for a time milled in. the common clothiers stocks; but it is desirable to avoid being` apt to produce an unequal oran uneven surface, called a. grain.

.'Vhat is claimed as the invention of the said THOMAS RourNsoN WILLIAMS isrlhe method, substantially as described, ot harder-ling` the bat by passing the same he tween two series or tiers of rollers covered j with cloth, or otherwise, and arranged over each other, the one series being' provided with a reciprocating cndn'ise niotion for the purpose ot' i'elting the bat, and the other series with a progressive rotary motion for l the purpose of feeding the bat through, with l or without the use of a trough containing` hot Water and soap-suds or other matter, suhthis, and a-t all events the goods should be iiuished,if possible,in this machine, thestocks stzintiallsv as described.
