WINDING-IMACHINE.

SPECIFICATION formingpart of Letters Patent No. 664,474, dated December 25, 190i).

Application filed December 18, 1899. Serial No- 740,623. \No model-J T aZZ whom it mag concern:

Be it known that 1, JAMES F. GORDON, a

citizen of the United States, and a resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Winding-Ma United States patent to Ward well,No.480, 157,

dated August 2, 1892-an increment or decrement of motion is given to the windingspindle at each end of the traverse of the guide in order that the turns of the thread, 2 5 yarn, or other material at the ends of the cop may not be so superimposed in the different layers wound on the spindle as to give the cop an angular appearance and prevent the formation of a solid cylindrical cop combin- 0 ing the greatest amount of material in the smallest space. This is accomplished in the machine described in said patent by a pawland-ratchet contrivance and in other cases by frictional devices, as described in another 3 5 United States patent to Wardwell,No. 506,959, dated October 17, 1893. These devices are apt to get out of order and are unreliable in their action, the pawl being liable to miss or gain a tooth on its ratchet, owing to the great speed at which the spindle isrun, and the contacting surfaces of the frictional devices are apt to slip on each other and to require frequent adjustment. I obviate these objections by a peculiar combination and arrange- 5 ment of change-gears to connect the camshaft (which causes the traverse of the guide) and the spindle-shaft, so that both are driven positively with each other and their relative speeds cannot he accidentally changed. I am 5o enabled by changing the connecting-gears to vary the speed of the rotation of the spindle relatively to the speed of the traverse of the guide and to secure any desired relation be= tween said speeds.

-In a winding-machine adapted for thewind= ing of yarn, thread, or similar material of the sizelof No. 3 three ply (equal to No. 1 single ply) on a quill or tube in the spiral manner above indicated, assuming that the quill or tube is two and a half inches in length, I have found by experience that the yarn should be laid on the quill at such an angle as to traverse from end to end of the quill and back again in four and twenty-five twenty-siXt-hs revolutions of the spindle. Now in the case assumed if the spindle or bobbin holder were geared directly to the cam-shaft the gear on the spindle-shaft would need to have twenty-six teeth, or one and two twentyfourths inchesin pitch diameter, and the gear on the cam-shaft would need to have five times as many teeth less one-that is, one hundred and twenty-nine teeth-or a pitch diameter of five and nine twenty-fourths inches, and if a twenty-four pitch diametrical tooth (which is as fine a tooth as could well be used to getthe required strength) were used the centers of the shafts would be three and eleven forty-eighths inches apart. Now

to change such a machine to adapt it to wind a No. 50 three-ply (equal to a No. 16 twothirds one ply) yarn or thread would require the substitution on the spindle-shaft of an eighty-toothed gear having a pitch diameter of three and eight twenty-fourths inches and on the cam-shaft of a gear of fivetimes eighty teeth less one, or three hundred and ninety-nine teeth, and would require that the centers of the shafts should be nine and forty-seven forty-eighths inches apart. It 9 will be seen that the two gears in the first instance would occupy a width of space of six and twenty-two forty-eighths inches and in the latter case of nineteen and forty-six forty-eighths inches. The distance apart of 5 the two shafts cannot be changed without readjusting the position of the guide andother parts, which would be impracticable. The only way to avoid the moving apart of the shafts would be to place them at the greatest I00 distance apart ever likely to be required and to bridge over the space between the gears manner if the spindle-shaft gear has eighty "teeth andthe quill is five inches long the by an even number of intermediate gears even, because an odd number of intermediate gears would reverse the motion of the driven shaft. If twice as long a q'uillthat is, a quill five inches long-were to be used, the yarn being the same, the spindle would need to be revolved twice as fast relatively to the speed of the cam-shaft to lay the yarn at the same angle on the quillthat is, the twenty-sixtoothed gear on the spindle of the case first supposed remaining the same the gear on the cam-shaft. would need to have ten times twenty-six teeth less one, or two hundred and fifty-nine teeth, or a'pitch diameter of ten and nineteen twenty-fourths inches, and in like cam --shaft gear would require ten times eighty teeth less one, or seven hundred and ninety-nine teeth, and a pitch diameter of thirty-three and seven twenty-fou rths inches.

It will be understood that the .cam mnst be changed to vary the length of the traverse.- It will also be understood that with the spindle-shaft and the cam-shaft connected by direct gearing two'or three difierent sizes of coarse yarn or thread might be wound without a change of gears, and the same is true toa greater extent of the finer numbers of yarn orthrea,dthat is, the gears which are suitable for a given nu m ber of yarn will'serve for the next finer numbers; but the finer nu m-,

here will in that case bemore loosely wound and the maximum amount of yarn'will not be ;many..teeth the winds will crowd upon and overlie the other winds of the same layer. The finer number (50 three ply) mentioned above is a medium-sized yarn. Now in winding very fine yarn requiring a gear on the spindle-shaft with a large number of teeth the number of teeth on the cam-shaft would be something enormous and the diameter of the last-named gear would beout of all proportion to the size of the frame of the machine and to the cost of construction in other respects. It is evident that in the case assumed the number of teeth in the driving; gear must be one less than the number of teeth on the spindle-shaft gear multiplied by the number of revolutions of the spindle to' one traverse of the guide-that is to say, this ratio must be preserved, although, of course,

the number of teeth in both gears may be; multiplied by the same number,with'out any useful efiect, however, as the gears if the number of teeth were doubledwould be merely twice as large. "If a train of gears were used to connect the cam-shaft and spindle-shaft, the gears of the train could not be v so compounded as to give the desired result, because the intermediate gears would need to make a greater number of revolutions than the cam-shaft and the number of teeth in the gear which directly drives the spindle 'g'ear should be a multiple or the number of teeth in said spindlegear less one, and as said drivinggear makes more revolutions than the cam-shaft the spindle will lose or gain an amount as much greaterthan is required as the speed of the intermediate gears exceeds that of the cam-shaft. For instance, if the intermediate gear makes two revolutions while the cam-shaft makes one revolution the loss or gain will be doubled.

My'i'nvention also embraces a stop-motion device which stops the spindle and guide when the cop or the yarn breaks, an automatic tension device, and means of stopping simultaneously the motion of the spindle and guide without stopping the main shaft.

Said invention consists in the devices and combinations hereinafter described and claimed. 7 I

In the accompanying drawings, on three sheets, Figure 1 is a left-side elevation of a winding-machine embodying my invention;

Fig. 2, an enlarged side elevation of the tension device, partly in central vertical longitudinal section; Fig. 3, a vertical longitudi- 'nal section on the line 3 3-in Fig. 4.; Fig. 4, a front elevation ofsaid machine; Fig. 5, a vertical transverse section o'n'th'e line 5 5 in Fig. 1; Fig. '6, a front elevationof the latch of the clutch-locking me'chanisinand its connections, partly in section; Fig. 7, a-plan of the parts shown in Fig. 6, together with the shipping-lever; Fig. 8, a right-end view of the latch, the latch-releasing slide, and a part of .the drop-wire. 4

In the accompanyingdrawings, A represents a frame of any suitable construction, which supports the moving parts of the machine.

B is the main shaft or cam-shaft, which may be driven continuously at a uniform speed in any usual manner. A heart-grooved cam C is loose to rotate on the shaft B, but is prevented from moving endwise'on said shaft by any usual means. From the cam O'projects one or more pins 0, adapted to be engaged by another pin or other pins 0, which project from the adjacent face ofa collar 0, which surrounds the shaftB and-is rotary there- 'with, but is free to slide longitudinally thereon, said shaft and collar being connected by a spline or feather c or otherwise in any wellknown manner. When the pins on the collar O and the cam 'O are in engagement, said cam revolves with the shaftB and gives a reciprocating endwise movement to a guide-rod 01, provided with a cross-head d, rigidly attached thereto and having a stud (P, which laterally fills the heart-shaped groove 0 The upper partof the cross-head d. slides on a bearing-rod d arranged parallel with the guide-rod d and supported in brackets a a on the frame A. The guide-rod dis further limited to a longitudinal motion by bearings in a bracket a on the frame A and in the front a of said frame. In front of the frame (at the left in Fig. 3) a guide D of usual construction is secured to the guide-rod (1, said guide being preferably a plate or strip having in its free end a notch 01*, Fig. 1, to receive the thread, yarn, or wire being wound. A gear B is fast on the shaft B and engages a pinion e, the latter engaging a gear 8, fast on an intermediate shaft E in the drawings, Fig. 5, represented as a hollow shaft or sleeve, which turns freely on the spindle-shaft F and has a definite number of complete revolutions to each revolution of the main shaft or camshaft B or, in other words, to each complete traverse of the guide D. Another gear B fast on the shaft B, engages a pinion f, which engages a gear f, fast on the hubf of the disk f said disk turning freely on the intermediate shaft E. Two gears e f turn with the intermediate shaft E and spindle-shaft F, respectively, one of said gears having a l r with a circumferential groove 0 g to receive slightly-greater number of teeth than the other. is represented as having onetooth less than the gear f, the numbers of their. teeth, respectively, being represented as twenty-five and twenty-six. Thegears e f are concentrio and of the same outside diameter, one or both of said gears being slightly out of the regular proportion to make their diameters equal. An intermediate gear f 5 turns loosely on a stud f which projects from the outer face of the disk f and engages both of. said gears 6 f so that the gear f must revolve when the gear e is revolved with the shaft E, the gear f having the greatest number of teeth, at each revolution of the other gear (2 falling short of a complete revolution by the angular space measured by the number of teeth which it has in excess of said other gear 6 The studf is adjustable in the radial slot f of the disk f to enable the gears eff to be replaced by others having a larger or smaller diameter. Relatively to each other the gear 6 is the driving-gear and the gear f the driven gear.

From the foregoing description it is evident that if the disk f and the-shaft E revolve at the same rate of speed the intermediate gear f will not turn on its center, but Will merely lock the two gears e f to each other. It will be seen also that if the number of revolutions of the disk f is one less than that of the shaft E to a complete revolution of the main shaft B the spindle-shaft F will lose (the gears 6 f having the number of teeth above stated)one twenty-sixth of a revolution in every revolution of the main shaft, or, in other words, in every complete traverse of the guide D; also, that if the relative speeds of the shaft E and the disk f be reversed the spindle would make a corresponding gain in each traverse In the-drawings, Fig. 1, the gear 6 open said clutches.

of the guide; also, that maintaining the same speeds of the shaft E and disk f and changin g the place of the gears e f witheach other the result would be reversed-that is, the loss of the spindle-shaft would become a gain.

Motion is communicated from the spindleshaft F to the bobbin-holder or spindle F by miter-gears f 6 f said spindle being arranged parallel with the rod d and line of traverse of the guide D and at right angles to the main shaft B. The spindle F is supported in a bearing-sleeve a, in the front end a of the frame A and is provided with any usual means of retaining a tube, quill, or bobbin E thereon, as a toothed annular shoulder 7, between which and a nutf turning in the front end of said spindle, said tube, quill, or bobbin is held. The miter-gearf is loose on the spindle-shaft, but is caused to rotate with a collar G, similar to the collar .0 above described as carried on the main shaft, said collar G having one or more pins g, adapted to enter one or more holes f in said miter-gear.

Each of the collars G and G is provided the free end of one arm of a lever, represented as a rock-shaft H, provided with oppositelyextending arms h It, so that turning said shaft will throw both of said collars into or out of clutch with their respective counterparts. A spring, represented as-a spiral spring 72 surrounding the shaft H and attached atone end to said shaft-and at the other to the frame tends to rotate said shaft H in a direction to The rock-shaft is normally prevented from turning by a latch I, pivoted on the front of the frame A and having a notch i), which drops down over a pin h projecting from a third arm h, with which said lever H is provided and which serves as a handle to rock the shaft H into a position to couple the cam O to the main shaft and the miter-gear f to the spindle-shaft, and thus to set the spindle F and guide D in motion when the main shaft is running. When the free end (the right end in Fig. 4) of the latch -I is raised, the spindle F and guide D are allowed to come to rest.

A tension cam-slide J is by a tension-studj and by a guide-screwj, supported on the front a of the frame A, said stud and screw passing through a longitudinal slotj" in said cam-slide.

On the tension-stud j are arranged, Figs. 1, 2, 4, 6, and 7, aspring-chamberj or hollow cylinder having a closed end j through which said stud passes; a springj surrounding said stud within said chamber j; a collar j, which enters the outer open end of said chamberj a pair of dished tension-washers j f, with their convex surfaces next each other; another collarj", and a nutj which turns on the screwthreaded outer end portion of said stud j to compress said spriugj to the desired amount.

The thread or other material to be wound guided vertically 7 on the back of said slide and the lower end passes Between the tension-washers through the notch 02 of the guide D to the tube or bobbin "F3.

Theupward movement of the slide J is limited by a nut j, turning on the upper end portion of a'screw-threaded rod said rod below'said nut passing loosely through an ear of said rod b'eing'hooke'd through or otherwise secured to'said latch, near the outer end of the "saine, as shown in Figs. (Sand 7. Evidently when the slideJ is raised su fiiciently it will lift the nut j, rod and latch I and release the rock-shaft H and allow the clutches to, be

opened, as above described. The slid'e'lis raised by a bent lever 'K, one arm 'k'ofjwhic'h reaches under a projection 7' from 'said slide or otherwise engages said slide andthejother arm is of which carries anantifriction-roll I0 which rests'upon the surface of the cop'L or mass of material'already wound upon the quill b l'fbobbin. The outward pressure 'of t'he 'growanew the clutches to be opened.

1 incline J rises and allows the spri'ngj toe'X- pand-and thetension-washers J j to separate. 1 When the filled tube orbobbin i's'remove'd from the bobbin-holder orspindle F the lever K' and slide J are'retu rned to position by the weight of saidfslide, "which may "be assisted "bythe contraction of a spring 3' stretched between said'slid'e anaam of the frame.

To stopth'e spindle F and guide D'when' the yarn breaks, a drop-wire M,-having at theouter enda'hook m and at the other end m being pivoted-to the {latch-lifter N, isjused. The'lifter N slides in a cap n,secured on the frame at right angles to the latch -I, andisprofvided with an inclin'en, which when "said lifter N isdrawn forward raises said latch and It'isevident that as the slide J "rises the thin'edge 'of the wedge-formedhy said slide Jand the releases thelev'er'H, wit-lithe resnlt hereinbefore stated. I A stop projection 12. on the side of the latch-lifter N, which strikes against the cap n, prevents said latch-lifter from being drawn too far back by a spring n, which is stretched between said projection andthe 'rearpart of said cap to restore said lifter to position. The free or hookedend m of the drop-wirevis supported by the tension of the port-ion of the yarn or thread stretched between the tension-washers and the notch df 'ioffthe guide D; but when said .yarn or thread breaks or'bec'om'es too slack-(as might happen if the yarn or thread got out from between the tension-washers) said hooked'end is caught by the guide D, which draws the lifter forward .and raisesthe latch.
