Figure 3, sheet 2isn front side elevation utter o. portion ofthe top girt A has been removed, to show the connecting pointe-of, und the levers, arms, orconnecticns by which the friction-pulley B is brought into or released from contactwith the stationary shoe C. Y Y' t t vFigure 4, Asheet2, is e central horizontal plone section oi the gearF und pinion a, whoh'connect with the fritation-pulley B'to operate the 's nme. i K

This inventionconsists, first, in u stjotionnry shoe, C, secured to the hack girt A or othersuitahle support, und t friction-pulley, B, beneathit. When -said",.friction-pulley isfastene tothe {shuit of the pinion a, between the arm b und the shield D, (which'form the swinging yoke,) the upward motion brings the frictiong pulley into conttictivith the shoe C, to .the motion of the pulley, andthe downward motion of which yoke releases the pulley'from contcct'with the shoe, undzullowsth'e pulley to turn;` second, my invention consists in the swinging-yoke shield D,'e.rranged on th'eeentslshaftiE, end forming a. ense to enclose the geurF and. pinion a, to prerentlsand, dirt,'or the short ln-e-of c ot'tbnngetting on to the gear or pinion, oribetiveen the teleth of'lld gen1* t clo'g'or'wedr the suore. sh'ieiduisc cmss-ocnvenienrsupport-for'-mend vof" the kpinioli-zsh'eft,' which passesI 'through the frictionepulley, and'enters the arm b at the junction of the horizontal end 'vertichl portions b and thereof. v Y' YA weight, j', is suspended from the lever g, near the end, 7;', b y e stirrup, l, which may he moved along onthelever in either direction to increaseor d igninisli'the elfect ofthe weight upon the lever. At=euch end of the lop-heed s; vertical sliding ruck, H, is arrenged,. ond; zonthxe' ytoplofl, each rock-bur 'isn weighty heed, 'to rung the racks'downwhen desired. 'i On euch end of thelsh'eft E, sind-outside ot the frame, o pinion-gear, k, is secured. These p nions gear into the teeth of the vertical reeks, byffwhich they'm'eyhe operated in either direction. The 'usuel rollsor cylinders J'ure'employednnd etbovejthese `rolls, und between them, is the movable lap. roll The weighted heads of the'rnckfbershook on tothe ends of the roll m and hold it down, subject to the action of the lap of cotton and the hrake'wlien the rnalchine' is in operation. 'f I The cottonpaftr p'ussing thronghvn'rious operations', .is'formed into e sheet or lop, which'pesscs under und issrolled ori to and ei'ou'nd the roll m, and as the lap'o'tootton is winding on to said'roll, and gradually enlnrgs ing in dimeter, there is 'n continued and increasing upward stroinlon the racks to turn the Apinion 7c and shaft E, and allow the roll m t'o rise too rapidly, therebyminding nvloosc, uneven lap; Informing or preparing laps' ofcotton for csr'dingit is-vei'y important thet iep ot'preriouslyeprepared cotton shouldl be wound onto the mit as evenly and'a's closely ne een be conveniently done', so that when e. lap of cotton isl pla-ccd on the carding; engine, such'clcs'enndherd-wound lap of=ootton will supply the curdo. longer time. 4

A In the use 'ot my iniproved brake for cotton-lnppers, the inovc'ble wcightj on the lever g, connected-with the topot the nrm vraisesthe yoke, und holds theA friction-pnlley B -in contact with 'the stutioncryshoe C, -und produces .'continued, "oven,,sind equal strain on -thernckm' preventing. seid rocks and the roll/(n rising too rapidly, huthbldiugspidiroll downonfthet'ops of the eylix1ders'\ ,nnd between them, and vinding the ylisp ot' `eotton onto, roll m very evenly, closely, und completely.

The foot of the operator is removed from the foot-lever G, und the feed of the ninenine thrown into action, the lnp of cotton guided under and nround the roll m, nnd another lap formed ns before.

K It will therefore beireadily seenthet the shield D end arm L rform n. very convenient yoke and support for the friction-pulley B and pinion a, and that the shield serves a. still further purpose of keeping send und dirt out ofthe teeth ofthe gears. It will also he seen that the stationary shoe C is n. very permanent and substantial'deviee 'for controlling the action of the friction-pulley B and other connections, and that the connecting-rod d, between the feet-lever G and the weighted lever g, keeps the brake constantlr underthe control ei" the operator. i n

Having fully described my invgtion, ivhnt I claim as new, and desire te secure by Letters lntont, is

1. I-clnirn the stationary shoe C, combined vith the Afrietion-pnlleyB :md swinging yoke, in the manner and for the purpose substantially es specified.

2. I claim the swinging yoke, consisting of the shield D and nrrn b, arranged nnd applied substantially in the manner and for the purpose set forth. v

i 3. I claim the shield D, arranged to cover the gears, :1nd ferm one bearing or supportv for tlieshnft ofthe pinion a and pulley B, as explained. l

4. claim thecembinntienof the shield D, gear F, pinion a, friction-pulley B, stationery shoe C, crm or lever 6, transverse lever g, weightf, connecting-rod d, and foot-lever G, all arranged to opernte substantially ns nnd'for the purposes set forth.
