.MECI-IIANIS'MVFOR STRIPPING THE FLATS OF CARDlNG-MACHINES.
SPECIFICATION forming part 'of Letters Patent No. 244,546, dated July 19, 1881,
i I Application filed september l7, 1880. (No model.) I
- To alt-whom itmay concern:
Be itknownl-that I, GEORGE E. CHANDLER, of Lowell,in the county of Middlesexand State of Massachusetts, have invented an Improve ment inthe Mechanismfor Stripping the Flats of Garding-.Machines,of which the following is a specification.
The object of.my invention is to provide mechanism which can be applied to the cardstripping mechanism known as the Wellman stripper, to automatically drive it, during the act of raising and stripping the flats of a card ing-machine, at a different and greater rate of being broken away to show the train.
speed than it is driven while traveling from one flat to another, and at the sametime to effect such change in the speed of the machinery without jarring or straining any part of it.
My present device is an improvement upon the mechanism described in Patent No. 222,81 2, issued to me December 23, 1879. I attain the object ofmy invention by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is an end elevation of a portion of a carding-machine, showing the stripping meche anism with my improvements applied thereto{ Fig. 2 is'a side elevation of the same; Fig.3 is a view of the end'of the card-cylinder shaft with the'fast and slow speed pulleys and their? connecting train, part of one of the pulleys Fig. 4 is a section of the same on line A A, Fig. 3. Fig. 5 is a section of the mechanism shown in Fig.3 on lineB B of said figure. Fig.6 is an enlarged view of the wheels "0 and is seen in Fig. 3. Fig. 7 is a sectional view of the same. Fig. 8 is a sectional view of pulleyD upon line B B of Fig. 3. Fig. 9 is a sectional view of pulley E upon line B B of Fig. 3, showing the internal teeth therein. Fig. 10 is a section of the case F through the center on.a plane parparts are operated and the whole mechanism pulley, H, and train h, R, and 1", the pulleyH being driven by a belt, L, which receives motion from a pulley driven by the shaft a.
D is a pulley fast upon the card-cylinder shaft a, having attached to or formed upon its hub d the gear-wheel l9, whichprojects beyond the hub d and engages with gear-wheel 6, hereinafter to be described.
E is a pulley, adapted to turn freely upon the hub d, and having teeth out upon the inner surface of its rim, making it an internallytoothed wheel, into which teeth teeth of the pinion 70 upon the ratchet-hub 7c, hereinafter described, engage.
Fisaplate or disk having a rim, which forms a case of substantially the diameter of the pulleys D and E, and is attached to the frame G, which carries the stripping mech'anisnnor it may be attached to any adjacent part of the machine which will preventits rotation.- Upon .the plate or disk F is the stud h, uponwhich is placed the toothed wheel 0, which engages with the toothedwheel s and pinion j, rigidly Secured to the said wheel 6. There is also upon the. plate ordisk a stud, 9, upon which is placed the pinion k, which has upon. it a ratchet-hub, it, upon which the wheel c, which engages withthe pinion j, is freeto move in one direction, but is prevented by the pawl y from turning in the other, and the pinionk will, when the wheel 0 is revolved in one direction, be driven with it, but can at any time revolve at a greater speed in the same direction if any force be applied directly to its periphery independent of the wheel a. The pawl y is placed in a cavity cut in the wheel 0, and drops into thenotch cut in the ratchet-hub is, being held in place in the said notch, or into contact with the ratchet-hub;7c,when not in the notch, by a spring, as, placed in a channel cut in the wheel 0, these parts being covered by a washer, z, to exclude dirt or/ other foreign substances.
When these described parts are putin operative position the pulleys D and E have their rims abutting against one another loose ly, and the wheel s,moving with the shaft a, toe
drives the wheel a, to which is attached the pinion j which drives the wheel 0, which, through the pawl y and ratchet-hub k, drives the pinion k, which, engaging in the internal teeth of the pulley E, drives it in the same direction as the pulley D, but at a much slower speed.
By reason of the freedom of movement permitted to the pinion k, as above described, the pulley E may be rotated at the same speed as the pulley D if from contact with any object touching both at the same time the power of the faster is transmitted to the slower, so that a belt being shipped from one to the other, instead of slipping and wearing upon the one or the other, as one has a greater hold than the other, will drive both pulleys at the speed of the faster until it is entirely upon one pulley, after which it will move at the normal surface speed of that pulley.
J is a slotted cam attached to the cam M and moving with it.
K is a belt-shipper operated by the cam J, having its forked end swinging very near the pulleys D E. The cam J is so placed upon the cam-wheel M that the bifurcated end of the belt-shipper will be swung over and the belt shifted to the fast-running pulleyD just as the canrwheel M is about to raise and strip the flat, and swung back over and the belt shifted to the slow-running pulley E just as the fiat is replaced and the stripping mechanism begins to travel toward the next flat.
The operation of the stripping mechanism may be thus described: When the cam-wheel M is moving the stripping mechanism from fiat to flat the belt L, which drives it through the pulley H and gears ]L,R, and r in the usual manner, is held by the belt-shipper upon the slow-running pulley E 5 but when the cam M is about to lift and strip the flat the cam J changes the belt-shipper so as to carry over the belt onto, the fast-running pulley D. As soon as the belt comes upon that pulley sufficiently so that it has a hold upon it, although a greater part may still be upon the pulley E, the belt will be driven with the surface speed of the pulley D, and the pulley E will be carried forward at the same speed as the pulley D until the belt is upon the pulley D, when the pulley E will be again driven by the train of gears at its normal slower rate, the pinion It being driven rapidly by the internal teeth of pulley E while that pulley was acted upon by pulley D and the belt, and the pulley E being driven by the pinion k as soon as the pawl 1 drops, and reremains in the ratchet-notch of ratchet-hub k.
The belt remains upon the fast-running pulley and drives the cam M through the pulley H and gears 71, It, and r at a rapid rate while it lifts, strips, and replaces the flats. As soon as it has completed this operation the cam M, through its attached cam J and belt-shipper, shifts the belt L back onto the pulley E. As the belt edge passes upon the pulley E that pulley will be driven at the same speed as the other and will continue to be so driven until the belt passes entirely off from the pulley D, after which it will be rotated at the slower speed with which it is intended to move as the stripping mechanism moves from one fiat to another by means of the pulley D and intermediate train of gears. In this manner excessive wear, caused by slipping and consequent injury to the belt as it is changed from a pulley running at one speed to one running at another, is prevented, and the speed with which the stripping mechanism is driven is increased or diminished at the proper times without jar or shock to the machinery as the change is made.
What I claim as new and of my invention 1s 1. The combination, with the pulleys D and E, and mechanism for driving the same at different rates of speed relatively to each other, and permitting of the two being driven at the same speed, of the belt-shipper K, cams M and J ,and mechanism intermediate of said pulleys D and E and cams M and J, substantially as described.
2. The combination, with the driving-shaft a and two pulleys mounted thereon, one of which is fast and the other free to turn on said shaft, of a train of gearing provided with a ratchet pinion and pawl intermediate of said pulleys, a belt-shipper and stripper-arm, and intermediate connecting and operating mechanism between said pulleys and belt-shipper and stripper-arm, substantially as described.
3. The combination of the cams M and J, gear R, pulley H, belt L, fast-running pulley D, and slow -running pulley E, and speedchanging mechanism between said pulleys,with the belt-shipper K, which is actuated by the cam J, and which periodically changes the speed with which the cam M is driven by shifting the belt from one pulley to the other, sub-- stantially as described.
