VVIIILIAM H. WALTON, 0F NEW YORK, N. IMPROVEMENT IN CLEANING THE TOPFLATS OF CARDING-ENGINES.

Specification forming part of Letters Patent No. 16,196, dated December 9, 1856; Reissue No. 422, dated I January 137 1857.

directly above the other. From thence it passes to and between two small rollers, b b orb b', when used. The cotton from the lower feed, a, passes onto the iirst lieker-in cylinder c, that from a', when used, passes in the same way onto licker-in or Worker c. The two cylinders c c work together and partially straighten and equalize thetibers. From thence the cotton is taken onto the lickers-in d d', where it is again worked, in aid of which there is above and between d and c a small top worker, c. The course of revolution of these rollers is indicated by arrows, and they are driven by gearing in manner well known to machinists and carding-machine makers. A similar small roller to c is placed at c', nearer the main cylinder than c, which work the cott0n on the main cylinder f, and is stripped by the cylinder or licker-in d', which passes against the licker-in d. rlhe cotton received from c is repassed on the main cylinderf, with the cotton brought forward from the feeding-inrollers. Bythismethod thematerial is more evenly laid on the main cylinder before being presented to the dats or lags. The cylinder j' runs in contact with the lickers-in d and d', and from each receives the fibers for carding rapidly, evenly, and properly in quantity much greater than has ever before been effected in a given time. Cylinder f passes around to the iiats or top workers h, and thence to the doier i, whence it passes out of the machine in the usual way. Each of the iiats or top workerslbare clothed on bothsides,

and their ends rest on a ledge or screws on the permanent frame, outside of which there is an upward projection of the frame, having recesses in it, that serve for guards for round To all whom it may concern Be it known that I, WILLIAM H. WALTON, of the city, county,.and State of New York, have invented certain new and useful. Improvements in Carding Machinery; and I do hereby describe and ascertain my invention as follows, referring therein to the accompanying drawing, which is a vertical longitudinal section of my machine.

My invention relates to an improvement in stripping the top-flats or lags of machinecards by certain automatic apparatus, and in the combination, application, and arrangement of lickers-in acting as workers by heilig brought into contact with each other and havy ing intermediate small cylinder-workers in connection therewith. These devices consist of top-flats or lags suspended upon pivots placed in the center of their ends with toothed pinions upon them, by which they are raised from their position and turned over to be stripped, a rotating brush being employed to strip the flats or lags, which is so arranged as to be in its turn stripped by a cylinder card or Worker that returns the strippings to the lickers-in, four of which are worked in contact, actin g as workers to return the strippings along with the tiber fed into the machine properly to the main cylinder. This operation is continued till the whole fiber is properly worked and passes through the card.

The construction of the machine is as follows: The position of the main carding-cylinder, the dott'er, together with the construction ot' the same, are as carding-machines now in use, with one or two feeds, (in the drawing two separate points of feeding in are shown,) and intermediate between the feed-rollers and the vmain cylinder are four lickers-in, which are also made to serve the purpose of .workers and strippers, being so arranged and workin g together as to cause the cotton to be fairly and evenly presented to the main cardin g-cylinder, from which the unworked bers, Ste., are in great measure carried back to the lickers in and worked over and again presented to the cylinder, by which I make a saving of workers and strippers on the main cylinder as in the old method, and facilitate the operation of carding.

a a are the two rolls from which the cotton is delivered to the machine. They are placed one workers or top-dats 7L. At one end there is a pinion affixed to the j oint of each worker or toptlat 11,. An arm, 7c, is centered on the journals of axis of the main cylinder f on each side, which project upward above the top of said cylinder j, and form bearings for a cylinderbrush Z, of small diameter, and a clothed cylinder or doffer, m, a little behind and above. When the arms k sweep forward the brush which is in rapid revolution, driven by a band from the main cylinder shaft, brushes over and cleans the side of the flats or workers h, that is uppermost, the brush being in turn journals x, which project from the ends of the cleaned by the revolving card-cylinder m, whence the fibers are conveyed to the cylinder e', and are reconveyed upon the cylinder f. As the arms k move forward, as above stated, a projecting piece, 7c', strikes the workers or iiats and raises them from their bed, and vthe piece k on one side, being cogge'd, takes into the pinions ontheir journals and causes each tominake a semi-revolution, thus bringing the' not claim two sets of feed-rollers combined wlth a carding-machine, as they' have beforel been made and used; nor do 1 claimV two lickers-in working directly out .to themain cylinder, as they are to be'found on `machines previously devised; but

What I do claim as my invention, and for whichI desire to secure Letters Patent, isf- 1. suspending the top-flats or lags upon pivots in the center of the ends, by which they can be raised out of the Way of the adjoining ats or lags `to be turned by means of arack working on pinions upon their pivots, or the equivalent thereof, the whole being 4constr-acted and arrangedV substantially as herein described, for the purpose set forth.

2. Stripping the iiats or workers by a rotating brush so arranged that a card may in turn strip the brush and return the strippings to the main cylinder, substantially in the manner and for the purposes described.

3. The combination and employment ofthe lickers-in c c 'cl d and worker e, arranged substantially as herein described, and acting as workers and strippers, in the manner and 'for the purpose described.
