WINDING-ON MECHANISM FOR SPIN\HlJC.-`s-IVIULES.A

SPECIFICATION forming part of Letters Patent No. 286,460, dated October 9, 1883.

d Application filedA December '6, 1879.

To all whom t may concern:

Beit known that l, WILLIAM MoGonnnLL, of Vashingtou village, inthe county of Kent and State of Rhode Island, have invented cer tain new and useful Improvements in "Winding- On Mechanism for Spinning-'Mules of which the following is a specification.

This invention `relates to spinning-mules such as that shown in the patent to l?. Mc- Govern, No. 153,975, dated August 11, 1874, in which a quadrant-'Wheel is employed to effect the revolution of the spindles at a uniibrnily-diininishing rate as the cops increase in size to insure a uniform strain upon the yarn as it is being Wound. In mules of this class the quadrant is provided with a screw-threaded shaft carrying a slide, and the quadrant-chain is connected to this slide andpasses around and turns a drum or pulley that indirectly revolves the spindles. The said quadrant, and with it the screwthreaded shaft, has imparted to it a uniformly-oscillating motion, such motion being produced throughV suitable connecting mechanism by the movements oi' the carriage, and made to conform thereto. It istherefore obvious that, by varying upon this shaft the position of the slide to which the quadrantchain is attached, avariation in the amount 'of travel of such slide as the quadrant oscillates will be produced, and consequentlyT a corresponding variation in the number of revolutions of the drum and spindles which are indirectly revolved by said drum. Heretofore the upward movement of the slide has been produced by a Weighted clutch attached to the carriage, which at each stretch drops upon and drags along with it as the carriage moves inward an endless cord, thus turning a Wheel on the quadrant-axle, and indirectly, through intermediate cog-gear, turning the quadrantshaft, which latter,beingscrew-threaded, forces the slide upward, this construction being shown in the patent to l). McGovern, No. 118,808, dated September 12, 1871; but in this mechan ism the clutch is liable to slip. Besides, the ratio of decrease in the number of revolutions of the spindles at each succeeding Vstretch is normally constant and regular, Whereas it should vary, as is obvious in practice, so that there will be a uniform strain .upon the yarn as it is being Wound.

The object of my invention is to produce a simple and eicient mechanism which will obviate these objections and have a 'positive and uniform action, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of so much of a spinning-mule with my improved mechanism applied thereto as is nec essary for an illustration of my invention. Fig.

l 2 is a side view thereof, and Fig. 3 is a top or plan view of the same.

Corresponding parts in the several igures are denoted by the saine letters of reference.

Referring to the drawings, A designates the quadrant, and b is the screw-threaded shaft which is carried thereby, the latter being provided With a handle, d, at one end, and with a bevel-Wheel, e, at its other end, which Wheel e meshes with a corresponding bevel-Wheel, e, that is arranged on the shaft C5, on which the quadrant turns.

a drum, m, as shown. t is a cord or band by which power is transmitted from the carriage (shown in dotted lines) to the quadrant through a gear-wheel, that meshes with the quad rant, as shown in the patent to McGovern, No. 153,97 5, above noted.

B is a track that is secured on the floor at right angles to the shaft of the quadrant, and in this track travels a rack, C, having an upright arm, D,as shown. By the outward movement of the carriage it presses against the arm D and causes the rack C to travel toward thc quadrant. As the carriage recedes, the rack C is forced back by action of the spring E, that is connected With a horizontal shaft arranged at right angles to the rack, that carries a gear- Wheel, F, meshing with the rack C. V It is obvious that as the rack is forced toward the quadrant it Will wind up this spring E, which c is the slide on screwthreaded shaft b, and i is the quadrant-chain, which is secured to the slide and passes around i latter is fixed at one end, 'A5, to the side of 95 track B, which supports and guides the rack fixed ratchet-disk G in such a manner that when the shaft B5 is revolved toward the quadrant by the movement ofthe slide G as it is actuated by the spring E, the teeth of the said ratchet-disk G will pass under the pawl K as the disk G is revolved toward the quadrant with its shaft B5, and the loosely-arranged gear-wheel H will not be turned; but when the shaft B5 is turned in the opposite direction on the return movement of the slide C, the disk G, as it moves with the shaft,will have its teeth locked in engagement with the pawl K, and the wheel H, which is connected, as above described, with said pawl, will be carried around with the shaft The gearwheel H is thus revolved in only one direction-i. e., from the quadrant-while the shaft B5 turns in both directions. Therefore, when the carriage moves outward toward the quadrant, and pushes the rack C along by its engagement of the arm D, the gear-wheel Hwill be turned, as before stated, and this movement of wheel H is transmitted through an intermediate gear-wheel, L, to a gear-wheel, M, fixed on the shaft G5, on which the quadrant turns. As the shaft C5 turns, it operates to raise the slide c by means of the bevel-wheels e and e, the former of which being attached to the shaft C5, and the latter to the screwthreaded shaft b. The gear-wheel H is thus intermittently at rest and in motion, its motion being only in the one direction, and when the carriage moves back the wheel H and all the mechanism operated thereby, including the slide c, remains stationary.

It is obvious that the disk HS can be dispensed with, when the pawl K will be pivoted directly to the gear-wheel H, and the latter will be arranged closely to the fixed ratchetdisk G. Y

It is necessary, in order to maintain a uniform strain upon the yarn, that the slide c, which moves in a guide, D5, on the quadrantarm, should be raised less and less at every succeeding stretch. Therefore its upward movements are decreased by decreasing the distance for the rack C to travel in the track B back and forth, as follows: To the slide c is attached a chain, S, kwhich passes down and around a pulley, or between two pulleys, l and 2, as herein shown, and is secured at its other end to a wheel or drum, N, fixed on a shaft, E5, arranged at right angles to track B, and carrying another fixed wheel or drum, P, and also a cam, B. To the wheel P is attached a chain, T, which is also connected to adrag,VV, that moves .along in the track B. By means of this mechanism, as the slide cris raised, it

This disk H8 carries a piv.-

tively small, and largefor fine yarn. `the rate of the upward movement of slide clis easily varied by varying the size of this e wheel M.

causes the drag NV to move in track B, thereby shortening the distance for the' rack C to travel back and forth. When the slide c is raised high lenough, the shaft E5 will be around far enough to cause the cam B to bear on a lever, Z, to press it down outof a slot, F5, ina

bolt, y, that is arranged parallel with the shaft E5. The released bolt y is then forced by a vsuitably-arranged spring, 0, through a slot, G5, in the side of track B, and back of the rack C, to'prevent the return of the latter, sol that the mechanism operated by said rackG will be thrown out of operation.A A lever, Q, is .connected with the bolt y, and can be operated to return the said bolt back to its normal position against the tension of spring o.

The gear-wheel M upon the shaft G5, on which the quadrant turns, is to be changed according to the size ofthe yarn to be spun,

jfor the thicker the yarn the more rapid the decrease should be in the rate of revolutions of the spindles; hence for spinning coarse yarn the gear-wheel M should be compara- Thus U designates a lever that is fulcrumed on the end of shaft B5 and carries the gear-wheel L, the bearing-pin GG of which is adjustable in a slot, H5, in the said lever, so that the `position of the wheel L canbe changed to correspond with the size of the wheel M. At the free end of this lever U is fulcrumed a latch-lever, I5, which engages a bracket, J 5, to retain lever U down in position. Vhen it becomes necessary to change wheel M, the latch-lever 15 can be disengaged from the IOO bracket J 5, to enable the lever U to be thrown over to the position shown in dotted lines, Fig. 2, ofthe drawings.

The operation and advantages of my invention will-be readily understood and appreciated by those skilled in the art to which it appertains. It is simple and efficient, and is adapted for use in connection with mules other than those in the above-mentioned patents.
