SPECIFICATION forming part of Letters Patent No. 626,094, dated May 30, 1899.

Application filed. October 18, 1898. serial No. 693,874. (No model.)

To all whom it may concern:

Be it known that we, J on RAMsDEN, AR-' THUR TURToN TAYLOR, and JAMES RAMSDEN, subjects of the Queen of Great Britain, residing at Birstall, near Leeds, in the county of York, England,have invented certain new and useful Improvements in Self-Acting Mules; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the winding-on and copping or building motions of self-acting mules.

The object of our invention is to provide simple and effective copping or building mechanism for cross-winding the yarn in winding on such mechanism by the removal therefrom of the parts for giving reciprocatory motion to the front or acting faller and the substitution of the ordinary copping-rail, being adapted also for winding on the yarn in the ordinary way. Combined with the cross-winding motion we provide means for automatically stopping the cross-winding just before the carriage reaches the beam or rollers on its return or inward stretch in order that two or more plain turns of yarn may be Wound on the spindles. We also provide a locking device for locking the front and counter fallers together when they return to their positions of rest at the termination of each winding on and dispense with the chains heretofore employed for locking the front faller.

Our invention consistsin certain novel features of construction and operation of parts for the purposes above stated, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a side sectional elevation of the end piece of the head-stock of a self-acting, mule, showing in conjunction therewith, in section taken through the square or iron plate which connects the two parts of the carriage together at the head-stock, the mule-carriage in a position part way on'its return stretch to the beam or rollers when the winding on is taking place. Fig. 2 is a sectional plan of the long arm of the quadrant, showing the mode of reduplicaiion of the winding-chain for modifythe quadrant-drum 7.

ing the action of the quadrant and giving a uniform Wind. Fig. 3 is aside elevation of the faller+leg and parts and the means for giving oscillatory motion through same to the front faller-wire for cross-winding the yarn, the faller-leg being shown disengaged from the rooker. Fig. 3 is a detail side view of a modification of the lower end portion of the faller-leg. Fig. 4 is a front View, partlyin section, of the parts shown in Fig. 3, looking in the direction of arrow a, same figure. Fig. 5 is a plan view taken on line Z) c of Fig. 3. Fig. 6 is a side elevation of catch-lever and parts for effecting the premature stoppage of the cross-winding motion. Fig. 7 is a front elevation of-the part-s shown in Fig. 6, looking in the direction of-arrow (1, same figure. Fig. 8 is a plan of the device for locking the fallers, looking in the direction of arrow 6, Fig. 4. Fig. 9 is across-section through the fallershafts, showing a detail hereinafter referred to. Fig. 10 is an elevation of the combined copping-rail for cross and plain winding. Figs. 3 to 9 are drawn to an enlarged scale.

The same numerals refer to corresponding parts in all the figures.

In the drawings, 1 represents the end piece of the head-stock of a self-acting mule, and 2 2 the quadrant, which oscillates upon a stud 3 and has its oscillation given to it by the pinion t, mounted on the quadrant-drum shaft 5, which is driven by cord 6, passing around Within the long arm 2 of the quadrant and extending its entire length is the screw 8, which works the sliding block 9, wh ereto one end of the winding-chain 10 is attached, the opposite end of said chain being secured to winding-barrel 11. the exception that the quadrant-drum 7 is of With larger diameter than the drum now employed to give a slower and decreasedmovement and that the chain 10 does not pass direct from the sliding block 9 to the chain-barrel 11 the parts above described comprise the ordinary winding-on motion for revolving the spindles as the mule-carriage travels back to the beam,

as will be well understood'by those skilled in the art to which this invention refers.

Integral with or secured to the slidingblock 9 are lugs 9 in bearings, in which is journaled a stud 12, upon which are loosely mount- The smaller the amount of chain paid out ed and secured pulleys 12 12 On a stud 13, carried in a bracket bolted to the framing 1 intermediate of the quadrant and the mulecarria-ge, are mounted loosely other similar pulleys 13 13", these, however, being fixed as to position, while the pulleys 12 12 are movable. The winding-chain 10, instead of being attached directly to the sliding block 9, as heretofore, is first passed under and around the near movable pulley 12, then over and around the near fixed pulley 13, under and over the second movable pulley 12",and finally over and under the second fixed pulley 13", from whence it is taken and the end thereof made secure to the stud 12 or to the sliding block 9. This combined system of movable and fixed pulleys and the mode of red uplication of .the winding-chain enables the arc of movement of the quadrant to be minimized, so that it does not get beyond or much beyond the dead-center or vertical position at the farthest, and therefore the constantly-changing angular position of one point of connection of the winding-chain with the other point of connection thereof, as is the case with the ordinary winding motion, does not occur, and there is consequently a greater uniformity in the winding on of the yarn.

In connecting the chain 10 to the quadrant after reduplication around the fixed and movable pulleys the portion of said chain lying between the winding-barrel 11 and the pulley-blocks gives in the ratio of four to one of the are of movement of the sliding bloekthat is to say, if the sliding block moves circumferentially through one inch of space each portion of chain around the fixed and movable pulleys will be shortened one inch, and therefore four inches of chain will be actually paid out to the winding-barrel.

that is, when the sliding block is nearest the center 3the greater is the unwinding of chain from the barrel 11, and consequently the greater the velocityat which the spindles are driven, while as the sliding block 9 moves farther and farther away from the center so in proportion does the amount of chain paid out increase and reduce the unwinding from the barrel.

If a larger amount of chain is required to be paid out in proportion to the same movement of the quadrant, an additional fixed and movable pulley may be added, giving three fixed and three movable pulleys, which would pay out six times more chain than the extent of movement of the sliding block, or other numbers of pulleys may be used.

The paying out of the chain 10 is exactly proportionate to the exten t of circumferential movement of the sliding block 9, and therefore there is perfect uniformity of winding from the commencement of the cops to their completion, the angular variation arising from the increasing distance moved by the sliding block on the screw 8 away from center 3 not afiecting the winding motion.

eaoe i Referring now to the copping or building motion, 14 represents the mule-carriage; 15, the tin cylinder, mounted on shaft 16 and driven by gearing 17 from the winding-barrel 11; 18, the spindles, which are driven by bands (not shown) from the tin cylinder 15; 19, the faller-leg, connected at 20 to the front or acting faller 21, secured on the front fallershaft 22, to which are also secured arms 23, (one only being shown,) carrying the front faller-wire 24, extending from end to end of the mule-carriage and being actuated by said faller-leg to guide the yarn upon the spindles during the return traverse of the carriage from the extremity of its outer stretch to the beam or rollers; 25, the counter-faller shaft, and 26 the counter-faller wire carried by arms 27, (one only being shown,) all arranged in the ordinary and well-known way.

The faller-leg 19 instead of being in one piece, as heretofore, is made in two partsthat is to say, with a separate foot 19, which is provided on its face with a recess or groove 19, into which is adapted to enter and slide telescopically the lower end of the faller-leg 1f). Secured to the foot19 is a nut 28, through which works a screw 29, supported at its upper and lower ends in lugs 19 19, formed integral with the faller-leg 10.. On the upper end of the screw is fast a ratchet-wheel 30, held in position by a holding-pawl or detent 31, centered at 32 on a lever 53, mounted on the screw-spindle. The screw is actuated each time the carriage arrives at the extremity of the outward stretch or draw by means of a fixed finger 31, (see Fig. 5,) attached to any convenient part of the end piece 1 and in the path of said ratchet-wheel, so that when it comes into contact with the finger the latter engages with a tooth thereof and turns it around a distance equal to one tooth or more, as maybe prcdetertnined,the result being that the partial rotation of the screw 29 slightly raises the foot 1 9, and thus shortens the fallerleg, this being repeated each time the carriage reaches the end of its outward stretch and gradually shortening the faller-leg and raising the faller-wire 24 for each successive winding on of yarn to give the proper build to the cop. In thus effecting the building of the cop by a telescopic faller-leg which is shortened for every successive chase we do not require the shaperplates hitherto employed in mules for altering the height of the copping-rail. Therefore we provide a rail 35, having side ribs 36 36, which engage with the upper sides of a channeled bar 37, resting on the floor. To enable the rail 35 to be used for either cross or plain ordinary winding, we provide it on one side with a perfectly plain level surface 35 and on the reverse side with the inclined surface 35 (see Fig. 10) of the ordinary copping-rail. The rail is arranged with the level surface 35 uppermost, as shown, when crosswinding the yarn, but when ordinary winding the rail is turned over and the surface 35 presented.

The bar 37 forms a solid support for the rail 35 from end to end, and there is no liability of it springing or giving in the middle, as is the case when supported on shaper-plates at each end only, and consequently faulty building up of the cops is avoided. The pitch of the screw 29 is a varying one, getting coarser from the bottom to.the top, so that the changes made in the position of the fallerwire 24 at each successive winding on of yarn will increase as the building of the cops proceeds to give the abrupt taper required and compensate for the difference which the gradual upward movement of the taller-wire away from the spindle makes in the winding.

Fig. 3 shows a modification in the application of screw 29 to admit of the present ordinary faller-leg being employed. The screw 29 is supported at its upper and lower ends in lugs 19 19, integral with a bracket bolted to the rocker 38, and is arranged the reverse way to that previously described, the finer pitch of thethread being at the top and the coarsest at the bottom. The screw works through a nut 28, carrying the stud 60',which at each turn of the ratchet-wheel one tooth around is gradually lowered and causes the faller-leg to be lowered correspondingly to raise the front faller-wire the requisite distance to wind on each successive chase of yarn.

To cross-wind the yarn upon the spindles, the rocker 38 is made in the form of arectangular frame, which is carried, as before, by thelever 39, fulcrumed at 40 on a stud secured to a bracket bolted to the square. In said frame 38 and adapted to slide laterally therein is ablock 41, held in the frame by flanges 42 and havinga central opening therethrough in which fits a disk 43, which is secured eccentrically on a shaft 44, supported in bearings in brackets 45 4.5, bolted to the square. The eccentric 43' is provided with a slot 43, arranged diametrically of same, by which the position of said eccentric on shaft 44 may be adjusted to reduce or increase its eccentricity for the purpose of varying the length of nose according to the counts or equality of yarn being spun. shaft 44 is mounted loosely a small pulley or antifriction-bowl 46,which rests upon and is adapted to ride ove' the surface of the rail 35 and supports or ssists in supporting the parts. On the opposite end of the shaft 44 is secured a barrel or long boss 47, having attached thereto the ends of two separate cords 48 49, the opposite end of cord 48 being connected to a rod or spindle 50, supported ina bracket 51 at the rear of the head-stock, and the opposite end-of cord 49 being coiled upon and secured to a stud 52, carried at the end of a lever-arm 53, pivoted on a stud 54, secured to a bracket 55, bolted to the front of the end piece 1 of the head-stock. These cords wind and unwind themselves around and from the barrel 47 as the carriage moves out and in, the cord 49 being wound on the bar- On the near end of therel as the carriage travels out by the unwinding of cord 48, and the cord 48 wound on the barrel during the return traverse of the carriage by the unwinding of cord 49. I

When the carriage 14 is receding from the beam to the outer extremity of its stretch, the faller-leg 19 is detached from the rocker .38, as shown at Fig. 3, and is idle. After the Qratchet-wheel 30 has engaged the fixed finger ;34 at the end of the stretch and been moved the distance of a tooth or more to adjust or fshorten the faller-leg 19 said taller-leg is acted Eupou by chain 56, attached at one end to a loose scroll 57 on the tin cylinder-shaft 16,

then passed around a guide-pulley 58, carried up the taller-leg to the position shown at Fig. 7

:1, the recess at the bottom of the foot 19 passing over and engaging with the stud 60, secured to the rocker 38, thus insuring a positive movement of the faller-leg with the rocker. :The scroll 57 is actuated in the ordinary wellknown way to wind on the chain 56 and raise the faller-leginto engagement with the rocker 38. The parts being now in the position shown in Fig. 1, the carriage commences its return traverse to the beam to wind the yarn which has just been drawn and spun onto the spindles. During this return movement the cord 49, being held at its outer end, unwinds itself from the barrel 47, and thereby rotates it and also the eccentric 43, the latter, consequently oscillating the rocker 38' and the faller-leg 19 and parts,.by which means the faller-wire 24 is constantly oscillated during the winding on of the yarn and crosses the yarn first to right and then to left in building up its chase, thereby building up a firm compact (cross-wound) cop. On the arrival got the m tile-carriage at the beam the fallerleg is knocked off the stud 60, as ordinarily, and the parts resume the positions shown at Figs. 3 and 4, the succeeding outward stretch of the carriage, by means of cord 48, again winding the cord 49 around the barrel 47 in readiness for the next return traverse of the carriage, when the movements above described are repeated.

To wind ontwo or more plain turns of yarn for backing-off purposes, we automatically stop the oscillation of the faller-leg 19 just prior to the carriage arriving back at-the beam, in order that the remaining lengths of yarn may be wound in two or three straight coils on the spindle. The means we employ for this purpose comprise a catch-lever 61,

5 hinged loosely on the stud 52 of lever-arm 53, said lever-arm and a segmental plate 62, secured on a stud 03, carried by the lever-arm 53 and resting on a collar 64 (see Fig. 7) on the stud 52. On the outward stretch of the mule-carriage the lower end of the toothed segment 2 in its descent engages with the curved periphery of the plate 62 and forces it downward, said plate thus forcing theleverarm to the front of the end piece of the headstock, as shown in full lines in Figs. 1 and 6, and drawing the catch-lever forward until its extremity drops down against a shoulder 65, formed in the bed-plate of the end piece, whereby the catch-lever and parts are locked in the positions shown in full lines in Figs. 1 and 6.

The catelrlever 61 is connected by a length of chain 66 to the quadrant 2, which allows for nearly the full movement of the quadrant in the direction of the mule-carriage on its return traverse before it is drawn tight, and when this happens the pull on the said chain draws the catch-lever out of engagement with the shoulder and allows the parts to be pulled by the tension of cord 49 into the position shown in dotted line in Fig. 1, thereby slackening the cord 49, which consequently ceases to rotate the barrel 47 and stops the cross-winding of the yarn. The stopping of the motion of barrel 47 is timed to happen when the shorter radii of the eccentric 43 arrive over the shaft 44 and the faller-Wire is in its highest position, by which means the remaining portion of yarn will be wound on the top of each chase. In order to take up the slack of cord 48 caused by the stoppage of the rotation of barrel 47 before the carriage 14 arrives fully home, the spindle or rod 50 is surrounded by a spiral spring 67, which is confined between the bracket 51 and a collar 68, secured on the end of said spindle. The pull of the cord 48 when winding onto the barrel 47 compresses the spring (57 by drawing the spindle 5O forward, and when the barrel ceases to rotate, as before explained, the spring expands and takes up the slack of cord 48. The cord 49 can be tightened by rotating the stud 52, which is held when released by a pawl 63, which engages the ratchetwheel 52, secured on stud 52.

To change the motion so as to give a plain ordinary wind instead of a cross-wind, the cords 48 49 are disconnected, the shaft 44, with the eccentric and barrel, removed from the mule, the chain 66 detached from the quadrant, and the rail 35 reversed to bring the surface 35 uppermost. A small pulley or bowl similar to the bowl 46 is then secured on a stud which is passed through the slot (59, formed in the side of the frame or rocker 3S and fastened thereto by a nut, this bowl resting on and riding over the inclined surface 35 which gives the ordinary winding action to the faller-wire 24, the building being effected by the shortening of the faller-leg, as before described.

\Vith regard to the eccentric motion for oscillating the faller-leg for cross-winding the yarn, there are equivalent pieces of mechanism, such as a connecting-rod connected eccentrically to a face-plate or a pinion rotated bya toothed rail, which would give the same motion; but we find the eccentric and parts before set forth to give the simplest and smoothest motion and, with the self-adjusting telescopic faller-leg, well adapted to build up a firm and compact cop.

In order to dispense with the several chains which are required to hold the front fallerwire out of the way during the outward traverse of the mule-carriage, we employ a simple device for locking the fallers. On the fallershafts 22 and 25 are mounted, respectively, levers 7O 71, the former atits free end having a chamber 72 bored therein, into which enters the enlarged end 73 of a stud or pin 74, extending through a small opening into said chamber and held in position therein by a collar or head 75. Between the end of the chamber 72 and the part 73 of the pin 74 is confined a spiral spring 76.

The lever 71 is provided on its front side with an opening or recess 77-,into which when the said levers are brought together the enlarged end of the locking-pin is adapted to enter and engage the end thereof, as shown in Figs. 3, 4, and S. The rear portion of the lever 71 is bent or inclined, as shown in plan Fig. 8, so that when the fallers return to a posit-ion of rest on the conclusion of each successive winding on the said inclined surface engages with and bears against the end of the locking-pin 74 and forces it back into the chamber 72 until the recess 77 in lever 71 comes opposite thereto,whereupon the spring 76 impels the locking-pin forward into the recess 77 and locks the two levers, and consequently the fallers, together. To release the fallers when commencing the winding on, the chain 56 is lengthened, and instead of being fixed to the pulley 59, as heretofore, it is coiled completely around said pulley, then passed around a pulley 78, carried on a stud secured to the faller 21,and secured at the end to an eyelet formed at the end of the collar or head of the locking-pin 74. On the chain being wound upon the scroll 57 to draw up the faller-leg the pull thereon draws the locking-pin forward clear of the lever 71, thus releasing both levers and allowing the fallerwires to move to their proper positions, the front faller-wire over the yarn in readiness to guide it onto the spindle and the counterfaller under the yarn to put the necessary tension thereon, as shown at Fig. 1. To avoid the counter-faller wire rising too rapidly againstthe yarn when released, we attach one end of a chain 7.) to the counter-faller arm 27, (see detail Fig. 9,) said chain being passed around a fixed pulley 80 and connected at its opposite end to a lever 81, secured on the front faller-shaft 22. This chain initially restrains the upward movement of the counterfaller wire, and as the front faller-wire moves to its position for guiding the yarn onto the spindle the chain slackens and sets the counter-faller wire free to bear. fully against the yarn.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is- 1. In a spinning-mule, the combination, with a pivoted faller', of driving mechanism connected with the leg of the faller and operating to oscillate it, a screw of variable pitch arranged longitudinally of the said faller-leg, and tappet mechanism operating to turn the said screw periodically and to an equal extent at each operation, thereby varying the effective length of the faller-leg and adjusting the position of the faller-wire to an unequal extent at each operation, substantially as set forth.
