Application filed June 26, 1912. Serial No. 706,068.

To all whom it may concern: Be it known that 1, Guns RYDEN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new My invention relates to winding machines for winding thread and yarn into cops, bobbins or other forms of packages.

invention consists particularly of improvements in the structure and arrangement 4 of the mechanism of the machine whereby its efficiency is increased and its operation simplified.

The invention is fully described in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a front elevation of one unit or head of my improved machine arranged for winding cops at both ends of the winding-spindle, but with the winding mechanism shown at one end only. Fig. 2, an end elevation of the same; Fig. 3, a similar elevation, with the mechanism shown part-sectional on the line XX of Fig. 1; Fig. 4, a longitudinally-sectional view of the spindle clutch-device; Fig. 5, a plan view of the same; Figs. 6 and 7, detail views of the thread-guide and traverse mechanism; Fig. 8, a sectional view of the traverseframe dog and sector taken on the line Z-Z, Fig. 2. i

My new machine is intended to be built in gangs or series-of any suitable number of units or heads, but as all of the heads are of the same design and structure it has been considered suflicient to illustrate and describe only one. Furthermore, as both. ends of each head are substantially the same in construction and arrangement the parts at one end are not shown in Fig. 1 and need not be here described except to state that they operate in the same manner as that of the mechanism explained.

Referring first to Fig. 1, the main frame A of the machine consists of the base a and two side-members or uprights a, a, joined at the top by an arch or bridge-piece (1 The side-membersv 0,, a are formed with bearings a a for the horizontally arranged winding-spindle B and the base a has an upwardly projecting bearing a, for the horizontal rock-shaft C which extends at rightthe driving-pulley angles to the spindle B. As usually arranged, the rock-shaft C extends the whole length of the bed 'or table which supports the several units 61' heads and is operated by a cam 0r other'suitable device, not here shown or described. Suflice it to say that one rocker-shaft serves for the traverse-motion of the Whole series of heads and the oscillating motion may be imparted to the shaft in any convenient manner as now well known in the art.

Mounted on the winding-spindle B'is a driving-pulley B which is secured to the spindle by the set-screw b. The pulley B is driven from a driving belt, not here shown, preferably arranged to connect the pulleys of all of the heads or units to a com;

mon source of power, such, for instance, as of a motor or other prime-mover.

The side-members a, a of the frame A are formed with forwardly projecting cars a, a see Fig. 3, bored to receive a rod D which extends across theframe and projects therefrom at both ends. The rod D is secured in the ears 0,, a by set-screws d, d, and carries at its front end a bracket E held thereon by the set-screw e. The bracket E is formed with an arm or elbow e at the top of which is a bearinge Mounted to rotate in the bearing e is a live-spindle e which serves as a support for the outer end of the cop-tube an, illustrated by dot-anddash lines in Fig. 1. The spindle or cop tube-support e is preferably mounted in a sleeve or bushing e 'which is adapted to slide in the bearing 6 against the action of a spring, not here shown. This arrangement provides for the retraction of the spindle sothat the cop-tube may be placed in position thereon with its opposite end supported on the cop-driver F, but as similar devices are well known in the winding-machine art, the mechanism is not. here explained or illustrated in detail. The cop-driver F which acts to support one end of the cop-tube w and also serves to drive the latter, is mounted in the end of the winding-spindle B and is connected to rotate therewith by means of a clutch-device shown in detail in Figs. 4 and 5.

Referring to Fig. 4, the end of the spindle B is formed with an axial bomb and is also provided with radial teeth b see' Fig. 5. The cop-driver F is fitted to the bore 7) and has a teat f with a beveled end bearing against the end of the bore b. Mounted to slide on the cop-driver F is a clutch-member G in the form of a sleeve 9, carrying a flange g at one end. The opposite end of the sleeve 9 is formed with teeth 9 adapted to engage the teeth 6 on the spindle B. pin 9 extends through the cop-driver F with its ends engaging a slot 9 in the sleeve of the clutch-member G to secure the latter rotatively with the cop-driver while allowlng it to slide longitudinally thereon. The outer end of the co -driver F is supported in a ball-bearing which is held in a bracket 11, the latter extending up from the rod D and held in place thereon by a set-screw h, see Figs. 1 and 2.

The cop-driver F is formed with a flange which acts as a retainer for holding the balls 71. in the bearing H and also takes the thrust of a saucer-shaped spring 1 arranged between the flange and the clutch-member G, see Fig. 4. Normally the spring I tends to maintain the clutch-member with its teeth in engagement with those on the end of the spindle B so that the spindle and cop-drlver rotate as one. The inner face of the flange g on the clutch-member G is beveled at 9 and adapted to engage therewith is an oppositely beveled face y" of the clutch-lever J more fully described hereinafter. The end of the cop-driver F has a reduced portion 7. adapted to enter the bore of the cop-tube w and a spline or key f engages a slot in the end of the tube to rotate the latter, the arrangement being the same as generally used on machines of this type.

Projecting outwardly from a boss or hub a on the side-member a of the frame A is a rod K secured in position by the set-screw 7c. Mounted on the outer end of the rod K is a bracket K, held by the set-screw k, and formed with the upwardly projecting arm 70 terminating in a hub or 'bearin I0 Mounted in the bearing 76 is a horizontal rod L, secured by the set-screw Z, and extending through an ear a on the frame A, see Fig. 3. The rod L supports the traverseframe M, which controls the thread-guide N, and also serves as a track for the guideholder as the latter is reciprocated back and forth along the winding-spindle. The frame M is preferably formed with two legs m and m, see Figs. 1, 2 and 3, bored to receive the rod L on which the frame pivots. The upper portion of the frame consists of theback m formed with a curved top portion or cowl m at either end of which are two cars m, m. Mounted between the ears m, m, is a swinging bail O which is provided with pivot-pins or trunnions 0, 0 engaging suitable holes in the ears. The bail O normally hangs in the position illustrated in Figs. 2 and 3 and is operated by means later described to swing outward into the.

through the link q,

position shown in Fig. 6 to carry the yarn out of the notch in the thread-guide for the purpose hereinafter explained. The frame M is also provided near its upper edge with two ears m m arranged at either end, and through which extends a rod P. The rod P carries the dogging-lever S for the traverseframe to control its swinging movement as later explained.

The thread-guide N consists of a buttonshaped member n, preferably constructed of porcelain or other vitreous material, fastened to an angle-shaped support 91. by the screw 11?, see Figs. 1 and 6, and formed with a thread-notch or guide-slot n on its upper edge. The guide-support n is secured in a thread-guide holder a which is mounted to slide on the rod L as shown in Fig. 1. The guide-holder n preferably takes the form of a bifurcated arm having its legs a, n curled over to surround a sleeve 11, which fits the rod L. At one end of the sleeve n is a collar 11. formed with the downwardly projecting ears n 11,", between which is pivotally secured the end of a link g by means of a screw or pin 9. As here shown the holder 71; is secured on the sleeve n against the collar 91. by means of a split spring-ring n sprung into a groove on the periphery of the sleeve. This arrangement allows the guideholder to swing on the sleeve to adapt thethread-guide to move back away from the axis of the cop-tube as the yarn is built up thereon. The upper portion of the guideholder at is formed with ears n n bent around to form a slot adapted to receive the shank of the guide-support n and the latter is secured therein by means of the screw 12., see Fig. 6. The guide-support n has a portion a adapted to bear on a raised face m on the back of the traverse-frame M and also an upwardly extending finger n which is held in back of the rod P. By this means the thread-guide is adapted to slide in the traverse-frame M without swinging away from the back of the latter and pressure exerted on the frame acts to resist the move ment of the guide away from the axis of the cop-tube. Such pressure is usually provided by means of weights and I have here shown a weighted arm M fastened to the inner leg m of the frame M by means of the screws m m. The lower end of the mm M is provided with a cavity 'm, from which pro- JBCtS a rod '01,", and removable weights m are secured on the rod by means of the collar m held by the set-screw m.

The thread-guide holder 11. is reciprocatcd on the rod L by means of its connection, to the oscillating lever or rocker-arm Q. The arm Q is preferably formed of sheet-metal, to render it light in weight, and is secured to a crescent-shaped block q, see Figs. 1 and 2, fastened to the rock-shaft C by the screw 9 The arm Q is ease provided with two series of holesg, 9, etc., running its length and by adjusting the pin 9 in these holes the operative length of the arm is altered to regulate the length of traverse of the thread-guide. It will be understood that the double series of holes in the arm provide for connecting the two thread-guides at the opposite ends of the liable to cause its ends to bulge.

In my present invention my improved dogging device is arranged as follows: Mounted on the rod D is a sickle-shaped arm R, which I term the dog-sector, formed with an arcuate portion 0 extending up over the cop-driver F adjacent the sidemember a of the frame A. The hub r of the sector R is secured to the rod D by a set-screw a, see Fig. 3, and reaching down from the main portion of the sector is a web extension r formed with a hub r adaptedto surround a boss a which projects from the frame A. The arcuate portion 1' of the sector R is provided with a tapered groove 1, see Fig. 8, the bottom of which is formed concentric with the axis of the rod L on which the traverse-frame M swings. Secured to the rod. P which is pivoted in the frame M, as before explained,

is the dogging-levers arranged at one side of the frame and formed with an arcuate extension or shoe '8 adapted to engage the groove 7' in the dog-sector R. The shoe 8 has its sides tapered to correspond with the taper of the groove r, as illustrated in Fig.

8, so that when the shoe is forced into the groove it binds therein and prevents the frame M from swinging toward the axis of the cop-tube. It will also be noted that the form of the dogging-lever S is such that pressure on the traverse-frame in the opposite direction,that is, tending to carry the frame away from the cop-tube, will act to relieve the frictional engagement of the shoe s with the sector R, so that the movement of the frame in this direction is not resisted by the dogging-lever. The lever or dog S is controlled by a finger-lever S secured to the opposite end of the. rod P. This is preferably formed of sheet-metal with a forked portion 8 clamped to the rod P by the set-screw 8 A flat spring 8 is secured to the back of the lever S with its lower, curved end bearing against the back of the traverse-frame M and tending to force the dog S into binding engagement with the sector R; while pressure on the lever in the opposite direction will release the dog-from the sector and allow the frame to be adjusted manually to setthe thread-guide close to the cop-tube at the start ofthe winding operation. 7

The clutch-lever J which operates the clutch-member G, as before explained, is formed with a hub j mounted on a horizontal rod T and secured in place by the set-screw j The. rod T extends parallel with the rod D, in front of the latter, and is supported therefrom by the two levers T and U. -The lever T is'pivoted at one'end on the rod D and its opposite end surrounds the rod T and is secured fixedly thereto by a set-screw 23.

Preferably, the rod; T is milled down on one side at 6 throughout approximately its whole length, so as to provide a fiat bearing face for the ends of theset-screws which secure the various levers, .later described, firmly on the rod. The outer end of the rod T is bent down in the handle T which serves to rock the rod T in an arc around the rod D as a pivot. The lever U which helps to support the rod T is preferably formed of relatively .thin sheetmetal, see Fig. 1, and like the lever T is hinged on the rod D. Its rear end projects in the form of an arm uterminating in a curved portion u having an arcuate slot u' Referring to Fig. 3, the slot u? is engaged by the bent end '0 of a wire memberV which slides vertically in a bore m of the portion m of the traverseframe M. The upper end of the member V is bent over at o to adapt its forwardfend to engage a pin 0 on the end of the threadbail 0. Normally the position of the lever U is such that the curved slot. u? is concentric with the axis of the rod L so that as the traverseframe swings about this, axis the position of the member V is, not changed.

When, however, the lever U is rocked upward under the action of the stopping mechanism of the machine, as later described, the slot 1& acts to lift the member V to cause its upper bent end 0) to engage the pin 0 and swing'the bail forward into the position illustrated in Fig. 6. This rocking movement of the bail O lifts the thread or yarn y out of'the notch 12. in the threadguide N so that the;continued reciprocation of the latter, after the arrest of rotation of the cop, will not break or damage the yarn.

Mounted on the rod T, inside of the upright a of the frame A,is an arm W fixedly secured in position by the set-screw to, see.

Fig. 1, and having its upper end ofi'set at 'w. The inner face of the offset portion w of the v bearing at", extending from a lug a formed arm W is formed with a shoulder 'w adapton the top of the arch a of the frame A, and is held in place by the washer w and screw w. The lug a is counterbored around the bearing a to form a pocket a for a coiled spring to which encircles the bearing. One end of the spring w engages a hole a in the lug a and the Opposite end is carried through a transverse hole w in the hub 10* of the arm W. The torsion of the spring w tends to rock the arm W in the direction indicated by thearrow 2, Fig. 3, to hold its detent shoulder w in engagement with the shoulder w" of the arm W. When the rod T is rocked slightly in the direction indicated by the arrow 3, Fig. 3, the detent shoulders are disengaged and the force of the spring w will move the arm W upward. The lower end to of the arm W will then ride on the face w of the arm W and force the latter outward to carry the rod T still farther downward in the direction indicated by the arrow 3. This latter movement of the arm W as it swings the rod T downward carries the inner beveled end j of the clutch-lever J against the beveled face 9 of the flange g on the clutch-member G, to withdraw the latter from engagement with the teeth 12 on the end of the spindle B. The disengagement of the detent shoulders of the arms W and W may be effected manually by movement of the handle T and the stopping of the cop-driver is accomplished through such disengagement.

Automatic release of the detents is effected by the means now described: Mounted on the inner end of the rod T is an arm 6 secured fixedly thereto by a set-screw 7. A pin 8 is driven through a hub 9 at the top of the arm and its opposite ends serve as bearings for a pivoted lever 1 0. Preferably, the lever 10 is formed of wire bent in U-shape with its ends curled around the ends of the pin 8 and its lower crossbar 11 adapted to engage with the teeth 12 of a wheel 13 mounted on the winding-spindle B. The wheel 13.is fixedly secured to the spindle B by means of the set-screw 13 and rotates therewith in the direction indicated by the arrow 4, see Fig. 3. Normally the cross-bar 11 lies out of range of the teeth 12 on the wheel 13, but the lever 10 is arranged to be carried upward into the position illustrated in Fig. 3 by means of a crank-arm 14, formed by an extension of the wire of one side of the lever, see Fig. 1. The lever 10 also has another extension or tail-piece 15 arranged below the wheel 13 and adapted to engage the latter in the space 16 between the two rows of teeth 12 so that when the end of the lever is engaged with the teeth on the wheel it will not be carried upward thereby beyond its proper range of action, see Fig. 3.

The lever 10 is operated through the crankarm let by means of a lever 17, preferably formed of sheet-metal, and pivoted on the waeao boss a which projects from the side of the frame A. The forward end of the lever 17 is provided with a slot 18 with which the end of the crank-arm 1 1 engages and its rear end 19 is curved downward and provided with an arcuate slot 20. With the lever 17 in its normal position, as illustrated in Fig. 2, the slot 20 1S concentric with the axis of the rod L on which the traverse frame M swings, and he slot 18 is so related to the axis of the lever 10 that the latter is held downward with its end out of range of the teeth 12 on the wheel 13. When the forward end of the lever 17 is lifted the slot 18 operates on the end of the crank-arm 14 to raise the lever 10 into engagement with the wheel 13 and this upward movement is effected through a spring 21. The spring 21'is arranged on the inside of the upright a of the frame A with one end hooked through a hole a in a lug a on' the frame and the other end secured to an ear 22 bent over from the forward end of the lever 17. The lever 17 is maintained inits normal osition as illustrated in Fig. 2 by means of an end-stop-bar or lever 23. Pivoted in the ears 24, 24 on the back of the traverse-frame M is a rod 25 having its inner end bent in the form of a crank-arm 26. Secured to the bar at a point substantially midway of its ends is a lever 27 having its lower end bent around the rod and clamped by a screw 28. Adapted to slide in the slotted, upper end of the lever 27 is an extension 29 secured to the main lever by the screw 30. The extension 29 is preferably constructed of relatively thin, spring-metal and carries a thread-eye or guide 31 at its upper end. This construction of the end-stop-lever provides for a slight yielding of the extension 29 to allow for variations in the tension of'the yarn y which draws through the guide 31, and the resilience of the lever can be varied through regulating the operative length of the ex tension by adjusting it up and down on the lever 27. The lever 27 is normally held in a vertical position, as illustrated in Fig. 2, by the tension of the yarn y as it leads through the thread-eye 31 and is drawn down to the cop-tube :20. When the tension on the yarn is relieved, through breaking or exhaustion of the supply, the lever 27 is free to move outward into the position illustrated in Fig. 3 to allow the lever 17 to be rocked under the influence of its spring 21.

Mounted on the rod T on the outside of the frame A is an arm 32, secured by the setscrew 33 and having a screw 34 extending through its upper end in the direction of the cop-tube. The screw 34 may be slid through its bearing in the arm 32 but is prevented from turning therein by a pin 35 engaging a longitudinal slot 36 in the top of the screw.

Two check nuts 37, 37, on either side of the justed position. Atthe inner end of the screw 34 ispendulously supported on the pin 38 a cam-shaped button 39 which normally hangs in the position illustrated in Fig. 2, with its curved face downward and the point thereon nearest to the pivot 38 ad-- jacent the cop-tube w. The button 39 is adapted to be engaged by the periphery of the cop when the latter reaches its predetermined diameter to move the arm 32 to bring the stopping mechanism of the machine into action as more fully described hereinafter.

The operation of the whole machine is as follows: The cop-tube or quill w is placed in position by mounting its end on the end of the support or spindle e and the bushing 6* in which the spindle rotates is then pressed back against its spring a sufficient distance .to allow the other end of the tube to be No provision is made in the present inven-' tion for arresting the reciprocation of the thread-guide during the operation'of the machine, the relative slow movement of the guide being continuous as imparted by the continuously oscillating rock-shaft C which is connected to the thread-guides of the whole series of heads. The winding-spindles B are also rotated continuously from the common source of power at the end of the gang of units, but each individual copdriver may be stopped and started at the will of the operator, or automatically through the operation of its appropriate controlling mechanism. Previous to the start of the winding the cop-driver F is at rest with the clutch-lever J engaging the flange g of the clutch-member G to hold its teeth 9 out of engagement with the teeth 6 on the spindle B. To start the winding operation the handle'T is moved to throw the rod T upward in the direction opposite to that indicated by the arrow 3, Fig.3, and the clutch-lever J swings downward away from the flange g on the clutch-member G. This allows the .latter toslide on the clutch-driver F to bring its teeth g into engagement with the teeth 6 on the spindle B and the spindle and driver then rotate as one to impart rotation to the cop-tube m. The movement of the handle T as above described, carries the detent-shoulder w of the arm W into en- .gagement with the shoulder w on the arm W and the parts are held thereby to continue the winding operation of the machine.

The parts are now in the pos tions lllustrated in Fig. 2 with the curved arm at of the lever U depressed to hold the upper end of the wire member V away from the pin 0' on the bail O. This allows the bail O to hang free with its longitudinally-extending portion away from the yarn y and as the thread-guide N reciprocates back and-forth along the traverse-frame M the rounded edge of the guide-button n will ride in under the yarn and pick it up in the guide-slot 11. After the thread has been thus automatically plcked up by the guide the reciprocation of the latter will traverse it on the cop-tube to wind it in cross-helices or coils in the manner now well known to those versed in the art.

The upright position of the lever 23, maintained by the tension of, the yarn 3 drawing through the eye 31, holds the lever 17 with its rear end 19 raised against the action of the spring 21. The slot 18 in its forward end, through engagement with the crankarm 14, maintains the end of the lever 10 away from the toothed wheel 13 and with the parts in this position the crank-arm 26 is free to slideein the slot 20 as the traverseframe M swings backward to allow for the increase in diameter of the winding. Should the lever 10 upward into engagement with the teeth 12 on the wheel 13 and such engagement will force the arm W outward to release the detent shoulders -'w and 'w The disengagement of the detents allows the arm W to swing upward under action of its spring 41: so that the'arm W is forced still farther outward and the rod T moved downward thereby. The movement of the rod T downward carries the clutch-lever J into engagement with the clutch-member G to slide the latter and arrest the rotation of the copdriver F. As the rod T moves downward the inner end of the lever U is swung upward and acts to raise the member V to swing the bail O outward as before explained. This lifts the yarn out of the notch in the thread-guide N, as shown in Fig. 6, and prevents the guide from carrying the yarn back and forth in its reciprocation.

The machine is stopped at the completion of the cop by engagement of its periphery with the button 39 at the end of the screw 34. The screw 34 is adjusted in accordance with the required diameter of the cop and as the latter reaches this diameter its surface will contact with the inner end of the button 39 and turn the latter upward with the cam face riding on thecop. This causes the arm 32 to be forced outward to rock the rod T- downward and actuate the stopping-mechanism as before explained.

It will be seen that various other modifications might be made in the form and structure of the mechanism without departing from the spirit or scope of the invention, therefore, without limiting myself to the exact embodiment shown and described,
