IMPROVEMENT IN cartonne-lavalNes.

kSpecification forming part of Letters Patent No. 11,964, dated December 9, 1856; Reissue No. 422, dated January 13, 1857 3 Reissue No. 190, dated September l, 1857.

T0 @ZZ wwm, it may concern:

Be it known that I, WILLIAM lil. WAL'roN.l

of the city, county, and State of New York, have invented certain new and useful Improvements in Garding Machinery; and I do hereby declare and ascertain my said invention as follows, referring therein to the accompanying drawing, which is a vertical longitudinal scction of one form of my machine. f

My invention relates, rst, to stripping the top-flats of a machine-card by certain automatic apparatus; and, secondly, to the employment of two or more lickers-in,77 acting together as workers by being brought into contact with each other, for the purpose of working the ber before it passes onto the main cylinder, and also to the employment of small workers therewith. These devices consist of top-ats suspended upon pivots placed at 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 ats or lags, which is in its turn stripped by a small cylinder-worken'which carries back the strippin gs to the upper licher-in, and there bein g two or more lickers-in working together they act as workers, as above stated, and return the strippings straightened to the main cylinder along with the ber fed into the ma- This operation is continued until the whole ofthe available ber is properly worked and fed through the machine, by which a saving of waste is eected and greater rapidity Vgiven to the operation of carding.

The following is a description ofthe machine: a a are two rollers, from which the cotton is delivered to the machine. They are placed one directly above the other. From thence the cotton passes to and .between two small rollers, b b or b b', when these are used. The cotton from the lower roller, a, passes on to the lickerin opposite to it. That from a is delivered onto the licker-in above. This gives a double feed; but I sometimes omit one feed and simply feed onto the upper or lower licker-in. Of the series there are two lickers-in which worktogether to work and straighten the ber. These are lettered c c. They partially prepare the ber for the main cylinder. From them the cotton passes onto two other lickers-in when adouble series are used. These are in the drawing. lettered d d. There the ber is again worked, and for further aiding this operation there are smallworkers e e above. The course of revolution of these cylinders are all indicated by arrows, as shown in the drawing, and they are driven by gearing well known to machinists and carding-machine makers.

It is obvious that if but one set of lickers-in or workers are used, the feed froln a would be directly upon d', and if more were used bcyond e c the feed would be onto the outer, upper, or lower licker-in or worker, if one feed were used.

The small cylinder e', which works the cotton on the main cylinder f, is stripped by the licker-in d', which latter returns it to the main cylinder after working it with the licker-in d, by which it is parti-ally straightened and laid with the cotton direct from the feeding-roller. By this system of making the lickers-in Workers by running two or more in contact with each other the material is more evenly presented to the main cylinderf. The cylindcrf .runs in contact with the lickers-in d d', and from each receives the bers for carding, by which a much greater rapidity of carding is effected without clogging.

Gylinderf passes round to the ilats or topworkers `h with the bers received from the lickers-in, and thence to the doifer t', whence it passes out of the machine in the usual way. Each ofthe top iiats or Workers h are clothed on both sides, and their ends rest on a ledge or screws on the permanent frame, outside of which there is an upward projection of the framc,havin g recesses in itthatserve for guards for round journals X, which project from the ends of the top flats or workers h. At one end there is a pinion aixed to the stud ofl each worker or top flat It.

An arm, K,- is centered on the journals of axis of the main cylinder j', on each side, which project upward above the top of the said cylinderf, and form bearings for a cylinder-brush, l, of small diameter, and a clothed cylinder or doifcr, m, a little behind and above. W'hen the arm K sweeps forward, the brush, which is in rapid revolution, driven by a band from the main cylinder-shaft, brushes over and cleans the sides of the flats or workers h that are uppermost, the brush bein g in turn cleaned by the revolving card-cylinder fm, vwhence the bers are conveyed to the cylinder e and are reconvcyed upon the cylinder f as the arms a v 49o K move forward7 asabove stated. A projecting; piece,-K/, strikes the workers or tiats and raisesthein from-their bed, and the piece K', on one side being cogged7 takes into the pinions on their journals and causes each to make a se1ni-revolution, thus bringing,` the 'working-surface up to be cleaned, by the action of the brush Z, which succeeds. The arms K have a segment-gear, p, affixed to them that.n

gears into segment q on a revolving wheel, r, driven by gearing from the dotter t' 5 or there are two of these wheels r, and they run in opposite directions,v by which means the arms K vibrate rst forward and then back. The gear` l. Suspending the top Hats or workers upon pivots in the center of their ends, by which they can be raised out of the way of the adjoining iatsand'turned by a rack Working into pinions7 or the equivalent thereof, the whole being constructed and arranged substantially as herein described, i'or the purpose set' forth.

, 2. VStrippingv thetlats or workers bya rotating brush so arranged that a card may strip the brush and return the strippings to the main cylinder7 substantially in the manner and for the purposes described.

3. The combination and employment of two or more lickers-in acting as lickersin and workers by running in contact with each other, or their equivalcnt,'for the purpose of working1 the fiber before it enters onto the main cylinder, in the manner specified and for the purposes set forth.
