IMPROVEMENT' IN srenernns roe cAnDINefcYLINnnss.
TO ALL yWHOM IT MAY CONCERN:
Be it known that we, FLETCHER M. ABBOTT, of Boston', inthe county of Suifolk, and State of Massachusetts, .and EDWARD F. FIELDS, of Lewiston, in the county of Androscoggin, and State of Maine, have invented certain Improvements inrCardihg-Engines, of whichV the'following is afull, clear, and exact description,refer ence being had to the accompanying drawings, making part of this specification, innwhich- Figure 1 is a Vperspective View of a carding-engine, with our improvements, applied thereto.
FigureQ is an elevation `of one side ofthesame. i l
Figure 3 is an elevationV of its Opposite side.
Figuie 4 is a central longitudinal section.
The teeth of a carding-eugine frequently become clogged-with refuse cotton and other impurities, which require to be removed before the combing out of the lap can be continued.v Toeiiect the removal of these impuritie,'it has usually been thepractice to throw theA carding-cylinder out of gear and clean its Ateeth by hand. Where a number4 ofengines areA employed, a very serious delay is incurred in thus stopping them, and this operation, together with that of-cleaning the teeth, is laborious and inconvenient to perform. The doer Abeing moved independently of the cylinder, continued to revolve after the Vengine was stopped, and the sliver was consequently drawn out and broken. l t
We are aware that Letters Patent Yof Great Britain were granted to William Brown, on theltwentythird day of January, A. D. 17861, in which the cardingcylinder was cleaned while revolving, by a stripperwhich was moved to and fromit periodically, to canse the teeth of the stripper to engage with and disengage them `from those ofth'e card-cylinder. The means employed by him for moving :the stripper consisted in crank-p'n'8, put in motion by toothed wheels, in connection with a wormI and toothed wheel, the shaft of the stripper resting in vibrating bearings. We arefalso aware-that Letters Patent of Great Britain were 4granted 'to Joseph C. Rivett, on the thirteenthday of April, A. D. 1861, in which the vrevolution of the feed-rolls is discontinued previous .to and. while the stripper is cleaning the carding-cylinder; the teeth ofthe stripper also engaging with those of the .card-cylinder, and the latter being reversed during this operation.
The mechanism employed for performinghe above-mentioned functions consists chieyin worm-wheels, a ratchet, acting against catches, a pin, disk, auxiliary shaft, series o' levers, plate, bar, inclnes, 8vo., which is evidentlyof complicated construction. l i
Theobject of our invention is to siniplifythe mechanism for cleaning the cardecylinder, Vand consists in supporting the shaft of the stripper in sliding bearings, so Operated by a shipper as to cause the stripper to be instantly thrown forward to bring. its teeth close tothe teeth of the cylinder, without engaging therewithwheu the cylinder is being cleaned. And in connection with the above, our invention also consists in certain improvements in tbemeehanism for discontinuing the feed of the lap during the operation of cleaning the main cylinder. V 4
To enable othersskilled in the art to understand and us'eour invention, we will proceed to describe the manner ink which we have carried it out.
-In the said drawings, A represents the cylinderof a carding-engine, which is revolved by suitable power communicated to the shaft a, which carries 4a drum, B, over which passes a belt, b, which is placed` around and drives a roll, C, on a shaft, c, which opcratesthe crank of the clearing or dofer-knife D, and also drives a pulley', E, on one end of a shaft, (Z, which carries, at its other end, a pulley, F, over which passes a belt,
e, which drives a pulley, G, on a short shaftgf, resting in bearings g, projecting from the framework, (see fig. 7L is a bevel-wheel, and z a pinion, (both seen dotteth) secured to the shaft f,back of the pulley Gr, the
pinion z' engaging with a cog-wheel, II, on one end of the shaft 7c by which'the doifer I is revolved'. The bevel. wheel z gears into aV bevel-wheel, Z, on one end of along shaft, m, ofsmall diameter, which is revolved 'for a4 purpose to be explained hereafter. K K are a pair of feed-relis, for'supplying the cottonto the cnrdingL cylinder. L L are slotted guides, in which rest the ends of the shaft o f the roller, around which the lap is wound. M is a tinted roller, provided. with a cog-wheel, N, which rec'eves motion fromffthefrevolution of thefeedroils,by1ncansof a series of cog-wheels, (not shown,) andthns drives thc lap-rollfn"positivelyu O is a roller, of a. length equal'to that-of the cylinder A, provided with'cardfteeth, and serves as astrippeiffor eleening the teeth of the cylinder when clogged with the impurities contained in the cotton. lThis stripper is made toA slideclose up to the-cylinder, so that their teeth-may bebro'ught .quite close to euch other, without engaging, by means of the following device: Bothends the stripper-shattn, project through slots. o in the framework, and rest in movable bearings p, supported in brackets p', secured tothe framework. From one of these bearings, je, extends "an arm, P, igs. 1 and`2, which rests on a guideplate, g, the-outer end of this arm having projecting therefrom a short shaft, r, upon which are placed two pulleys, one, Q,'alfrictionpulley, which is brought Y.
up-against the periphery ofthe drum B, by ashipper or lever, R, -pivotcd to ani arm, 2s, of the movable hearing j?, and to a crank-wheel, S, and serves to revolve the shortshaft 1*, and'with it the other pulley, T, which drives a. pulley, t, on one end of the stripper-shaft fn, und thus revolves the strippen which, byfplacing a baror cleat behind it, and creating a draught, is entirely freed from dirt, the current of air being suiiiciently forcible, and so directed against the waste as to separate it from -the stripper while revolving, and ,to deposit it into a. receptaclel beneath the card-cylinder. By providingthe shortshnft o with pulleys of varying sizes,
`made to slide thereon. to bringthein in place against the periphery of' the drum B, the speed-ot` the stripper maybe varied vas desired, and bycovering the pulley Q with ruhberor other elastic material, it'mny be cenipressed more or less against thc'drum, so that the teeth oi" the stripper 'may beb'ronght to within the proper distance of those of the cylinder, without touching, the width of the space betwcen'the teeth depending on the quality ofthe cotton to be carded, and alsopn the condition of thc cylinder, according as it requires athorough or only a partial cleaning.
Thefced-rolls K are prevented from revolving while the stripper is' removing the waste'froui the cardcylinder by the following mechanism: The crank-wheel S is festencd to one end of a. small shaft, it, which carries at .its oth'er end a cranlewheel, U, similar tofthat of S, and is connected with its movable bearing p by .an arm, o, w is a rod, leading from the bearing, 'and provided with a bool: or clutch, to fitovcr e collar at .the back of a. Bevel-wheel, V, secured to one end of the shaft m, which turns within bearings y. vWhen the crzmlewhcels S U are vibruted, by throwing the shipper into the position seen in fig. 3, the bevel-wheel Vis thrown into gear with another bevel-wheel, W, on a short shat`tn', resting in a bracket, p, projecting-*fiom the side ofthe framework, (see iig. 3.).13. pinion, X, on this short shaft u', engages with and drives a cogwheel, Y,
i on the,v end of the lower feed-roll shaft, und causes :it to revolve. When the stripper is thrown ltoward. the carding-cylinder, the shipper is in the position seen in fig. 1, andthe' bevel-wheel Vis thrown out of conne" tion with `that ofiW, und the revolution of the feed-rolls, and consequently the supply of cotton theretois discontinued. Z are weighted levers, for pressing ,the upper feed-roll down upon its lower one, by which the revolution of theupper feed-roll is eilected.
What We claim es our invention, and desire to secure by Letters Patent, is
The mechanism, constructed and operating suhstantiallyfas described, for moving Aand regulating the stripper, as and for the purpose set forth.
We also claim, in combination with a stripping supported ineJ sliding bearing, a feed-connecting an'd disconnecting mechanism, substantially as described and forthe purpose set f'crth. i
