19 Claims.

This invention relates to improvements in winding and like machines and consists in automatically-operated means for winding a length of reserve yarn on the end of the cop-tube or other package support before the winding of the package itself is started.

One object of the present invention is to'provide a device of the character specified having yarn-controlling means for winding a reserve length of yarn on the cop-tube or package support for use in splicing to the end of another supply package in a series whereby the yarn may be caused to deliver continuously in a magazine type of creel. I

Another object of the invention is to provide a device of the type specified which is capable of winding the reserve length and transferring the yarn to the thread-guide for winding the package without imposing undue strain or excessive tension on the yarn.

Another object of the invention is to provide a device of the type specified which is convenient to thread in preparing the machine for operation and which may be quickly and easily reset after each complete winding operation.

Another object of the invention is to provide a device of the type specified which is simple in construction and adapted for use with practically all types of winding machines without alteration in the arrangement of the mechanism thereof.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment of the invention, by way of example, as illustrated by the accompanying drawings. In the drawings:

Fig. 8 is a sectional view on line 8-8 of Fig. '7.

Referring to the drawings, Fig. 1 illustrates a conventional type of winding machine comprising certain essential elements which are well known in the art. The operating parts of the machine are mounted on a box-like frame 2 carrying bearings for a horizontal windingspindle 3 and a parallel cam-shaft 4 arranged therebelow. The winding-spindle 3 overhangs the forward side of the frame 2' and carries a suitable form of cop-holder 5, herein illustrated in the shape of a truncated cone, for receiving the paper cop-tube C or other yarn-receiver, for example, a wooden cone, on which the conical package is wound. The winding-spindle 3 is driven from suitable power-operated means such as a belt-pulley 6 connected to the spindle by a clutch 7. The cam-shaft 4 is driven from the spindle 3 by a train of gearing 8 enclosed in a case or housing 9 at one side ofthe frame 2. A pulley 11 on the end of the spindle 3 is connected by a belt 12 to drive -a similar pulley 13 which, through the gearing 8, drivesthe cam-shaft 4 at a reduced rate of speed. 85

Mounted fast on the lower shaft 4 is a helically-grooved cam 14 which actuates the traverse-mechanism, next described, to reciprocate a thread-guide 16 to deposit the yarn, thread or other strand material on the package.

The traverse-mechanism is mounted on a traverse-fra'me 17 constituted by a horizontal bar or member 18 supported by opposite arms 19 and 21 which are pivoted to rock on the bearings 22 and 23 for the cam-shaft 4. The traverse-frame 95 17 is provided with an overhanging portion 24 projecting outwardly beyond the arm 19 and forming an extension of its main horizontal member 18. The two horizontal members 18 and 24 are provided with a groove 26, see Fig. 00 2, adapted to serve as a track or guideway for a sliding traverse-rod 2'7. The inner end of the traverse-rod 27 is connected to a' slide 28 which carries a roller or bowl 29 engaged with the helical groove of the cam 14. The outer end of the traverse-rod 27 carries an arm 31 in which is mounted the thread-guide 16 in a manner as next described. The arm 31 is formed at its upper end with a circular opening for receiving the guide 16 which is of the button type having a 1 slot or groove 33 for the thread, yarn or other strand to draw through.

The outer arm 19 of the traverse-frame 1'7 is extended below its bearing hub, preferably in a separate arm 34 attached thereto and terminating in a counterweight 36 which tends to maintain the traverse-frame in substantially erect position. Attached to the overhanging part 24 of the traverse-frame 17 is a plate or back 37 against which the thread-guide arm 31 bears to direct the guide 16 in a course parallel to the surface on which the winding is performed. In the .machine herein illustrated the traverse-frame back 37 has its bearing face 38 inclined at an angle to the axis of the winding-spindle 3 in conformity with the taper of the cone-holder 5, while in other instances the back may extend parallel to the axis of the winding-spindle when a cylindrical package is to be wound on the machine. Secured upon the traverse-frame back 3'7 by opposite screws 39 is a curved wire thread-bail 40 which extends parallel with the surface of the cop-tube and along which the strand slides during its traverse. In accordance with the present invention the thread-bail 40 serves to position the strand as it leads to the cop-tube C so that it will extend across the path of the threadguide 16, whereby the latter is caused to pick up the strand upon completion of the reserve winding to thereafter traverse the yarn to wind the package.

In the present drawings the machine is illustrated as operating on a yarn strand y drawing off from a supply arranged below, but not herein shown. The yarn draws upwardly through a tension-device 43 of any suitable construction, thence through a slub-catcher 44 and leads across a breakage lever 45 to the thread-bail 40. In winding the package the strand y draws through the groove 33 in the thread-guide 16 and the reciprocation of the guide causes the yarn to be traversed longitudinally of the axis of the winding-spindle for the full length of the package to deposit it in helical coils which build up in layers to form the package.

The present improved reserve winding device is arranged in relation to the above described mechanism as next explained. The reserve ,winding device is attachable to and supported upon the swinging traverse-frame 1'7 by means of a twisted sheet-metal strip 46 constituting a bracket or standard therefor. The end of the standard 46 is slotted at 47 to receive one of the screws 48 which secure the back 37 to the traverse-frame 17. The standard 46 is also formed with an upper slot 49 which receives the shank of one of the screws 39 for the thread-bail 40. The slots 4'7 and 49 providefor adjusting the standard 46 onthe screws 48 and 39 so that the reserve winding device may be positioned to properly.

locate the first coils of yarn with respect to the end of the package to be wound on the cop-tube C. After the device has been properly adjusted in position the screws 48 and-39 are tightened to rigidly attach the standard 46 to the traverseframe 17 to position the yarn-controlling device in close proximity to the surface of the cop-tube C at its base end thereof.

The present reserve winding device embodies an auxiliary guide or yarn-controller 52 which, as herein shown, is forked to provide a curved finger 53 and a shorter straight finger 54 between which is a V-shaped crotch or guideway 56. The guideway 56 is adapted to receive the strand 2/ which is maintained therein'in the position illustrated in Figs. 1 and 3 at the commencement of the winding operation to provide for winding the reserve length of yarn on the butt end of the cop-tube C. The yarn passes across the threadbail 40 and directly through the guideway 56 of the controller 52 to the cop-tube C. After the reserve winding is completed the controller 52 is automatically shifted into the position illustrated by full lines in Fig. 4 and shown by dotted lines in Fig. 5. Through this operation the yarn, without leaving the thread-bail 40, is transferred from the guideway 56 of the controller 52 to the groove 33 of the thread-guide 16 to be traversed during the ensuing winding operation to build the package with a warp wind.

The controller 52 is constituted as a part of a rockable lever or member 55 comprising bearing ears 5'7 and 59 connected by a lateral strip or crossbar 58. Projecting from the opposite end of the crossbar 58 is a finger-piece or lever 61 which serves as a means for manually rocking the member 55. The ears 5'7 and 59 are provided with alining holes, in which is held a rod 62 having its projecting ends journaled in bearing ears 63 bent at right-angles to the twisted upper portion of the bracket or standard 46. The crossbar 58 of the member 55 is formed with an angular latch or detent-lug 64 adapted to pass through a slot 66 in a horizontal plate or platform 6'7 forming a part of the standard 46 and to be engaged beneath the edge of a ratchet-disk 68 rotatable on the platform. The disk 68 is provided with a radial slot or opening '70 through which the detent-latch passes to release the member 55. Opposite the lug 64 an integral stop-finger 69 projects from the side of the crossbar 58 of the member 55. A spring '71 coiled around the horizontal pivot-rod 62 and made fast at its opposite ends to the stop-finger 69 and the standard 46 tends to rock the member 55 upon the completion of the reserve winding and the release of its detent-latch 64 from under the disk 68, whereby to alter the position of the yarn-controller 52 in the manner and for the purpose as later explained. The rocking movement of the member 55 under the action of the spring 71 is limited by the'contact of its stop-finger 69 with the end of a set-screw '72 adjustable in the standard 46 to vary the extent of throw of the yarncontroller 52.

The ratchet-disk 68 is journaled on a fixed stud '73 projecting upwardly from the platform 6'7 on the standard 46, the top of the disk being counterbored to accommodate a retaining flange '74 on the stud. The disk 68 is controlled by a helical wind-up spring '76 coiled about the stud '73. One end of the spring '76 is engaged in a hole '77 in the disk 68 and the other end held in a transverse slot '78 in the upper end of the stud 73, the tension of the spring tending to rotate the disk 68 in a clockwise direction as viewed in Figs. 6 and '7.

Secured fast to the upper reduced portion '79 of the disk 68 is an annular ratchet 81 having a series of peripheral teeth 82 extending throughout the greater portion of its circumference and terminating in a radial projection or stop-finger 83. The ratchet 81 is held fast on the disk 68 by means of opposite screws 84 threaded into the disk with washers 86 under their heads. The ratchet 81 projects slightly above the top of the disk 68 to adapt the washers 86 to bind thereagainst to clamp it fixedly to the disk. By loosening the screws 84'the ratchet 81 may be turned on the disk 68 to adjust the angular relation between the stop-finger 83 and the slot 70 whereby to regulate the timing of action of the yarn-controller 52. The rockable member is released to permit the shifting of the controller 52 when the disk 68 has been rotated to a prescribed extent to bring its slot 70 into register with the detent-latch 64.

Pivoted on a vertical stud 87 fastin the platform 67 is a lever 88 formed with a pawl 89 at one end for progressively engaging the teeth 82 of the ratchet 81 toprevent retrogressive movement of the disk 68 under the action of its spring 76. A spring '90 connected at to an ear 91 in the lever 88, and suitably at the other end to the standard 46,v urges the pawl 89 into engagement with the teeth '82. The lever 88 has a rearwardly-extending farm v92 adapted to be operated'upon to release the pawl 89 from the ratchet in the manner and for the purpose as later explained. I

The ratchet-disk 68 is progressively rotated in a contraclockwise direction, as viewed inFigs. 6 and 7, by means of a lever 93 carrying a pawl 94 engageable with the teeth 82 of the ratchet 81.

The pawl 94 is of spring-metal riveted to the side of the lever 93 at 95 and having a finger 96 at its upper end bent at right-angles to extend through a slot 97 in the end' of the lever. Projecting from one side of the pawl 94 is another finger 98 bent forwardly to adapt its end to be engaged by the curved finger 53 of the yarn-controller 52. Ihe lever 93 is pivoted on a depending portion 99 of the platform 67 by means of a stud 100 with the side of its lower arm engaged by the end of a leaf-spring 101. The spring 101 has a bent portion 102 overlying the forward side of the standard 46 and riveted thereto at 103, see Fig. 2. The lever 93 is rocked to turn the ratchet-disk 68 by the intermittent engagement of the thread-guide arm 31 with its lower end. As the ratchet-disk 68 is progressively rotated in the manner indicated the pawl 89 engages with the teeth 82 to prevent its retrogressive movement. Upon the return movement of the lever 93 the springapawl 94 yields to permit its end to slide back across one tooth to engage with a succeeding tooth. A stop-finger 10.5 secured fast on the standard 46 by a screw 104 is positioned to lie in the path of the lever 93 to limit its return movement. By adjusting the finger 105 to raise or lower its outer end the range of movement of the lever 93 may be regulatedto vary the extent of rotative movement of the ratchet-disk 68 under the action of the pawl 94.

The lower end of the lever 93 carries a contact-element or bunter 106 adapted to be engaged by the side of the thread-guide arm 31 at the end of each rearward stroke of the latter. The bunter 106 is secured fast on the lever 93 by means of a screw 107 passing through a slot 108 therein. By loosening the screw 107 the bunter 106 may be adjusted on the lever 93 to insure its proper contact with the guidearm 31 to effect actuation of the ratchet-disk 68.

The disk 68 is provided with a stop or pin 109 projecting from its periphery in position to engage against the side of the lever 93 after the disk has been turned to a position to cause action of the yarn-controller 52. The lever 93 is caused to make one more stroke after turning the disk 68 to release the detent-latch 64 on the member 55, thereby turning the disk through the space of one tooth to bring the pin 109 against the side of the lever to hold,the latter from .with screws 39 and 48 already in place. bracket 46 is adjusted in position with the yammoving back into position to be forcibly engaged during the further operation of the machine.

The post or stud 87 on the topof the standard 46 is formed with a threaded hole 112 for receiving a screw 113 by'means of which a cover or casing 114 is attached to the device to enclose its operating mechanism. The top of the casing 114 is provided with an aperture to receive the stud 73 whereby the casing is arranged to closely overlie the mechanism enclosed therein. The method'of operation of the complete machine is as next explained in detail.

As hereinbefore noted, the reserve winding device or yarn-control unit may be attached to standard types of winding machines to cooperate with the traversing means thereof without alteration in the mechanism of the machine. lhe

device maybe mounted on the swinging traverseframe of the machine by attaching it thereto The controller 52 located with its crotch or guideway 56 at a point opposite the base end of the coptube C, just outsidethe zone of traverse of the thread-guide 16. To prepare the machine for winding thecop-tube C is placed on its mandrel or holder 5 and secured thereto by suitable means as usually provided. With the thread-controller 52 held in initial position by the engagement of its detent-latch '64 inunder'the edge of the ratchet-disk 68 the machine is threaded up in the manner as next explained. I

The strand 3/ of yarn, thread or the like is drawn up from its source of supply through the tension-device 43 and slub-catcher 44, thence across the breakage lever, 45 and led over the thread-bail 40. The end of the strand is passed through the guideway or crotch 56 in the yarncontroller 52 and attachedto the cop-tubeC in any suitable manner as usually employed. Before, starting the machine to operate the traverse-frame 17 is swung back into erect position with the thread-guide 16 bearing against the surface of the cop-tube Cin the manner as indicated in Fig. 2 of the drawings.

The machine is started to operate by throwing the starting lever to connect the driving pulley 6 with the clutch 7 which is fast on the windingspindle 3. The spindle 3 is thus caused to be driven to rotate the cop-tube C to wind the strand thereon as it feeds across the thread-bail 40 and through the yarn-controller 52. Concurrently with the rotation of the winding-spindle 3 the traverse-rod 27 is reciprocated by the cam 14 to cause the thread-guide 16 to traverse backv and forth longitudinally of the axis of the coptube C. I

During the initial stages of the operation of the machine the yarn-controller 52 remains fixed in the position shown in Figs. 1 and 3 with the strand y drawing across the top of the threadbail 40 as shown most clearly in Fig. 3 and leading through the crotch 56 in the controller to cause it to be coiled about the base end of the cop-tube C without traversing it thereon. The strand 1; feeds from the thread-bail 40 through the yarn-controller 52 and thence directly to the surface of the cop-tube C as it draws downwardly from the controller in tangent relation to the periphery of the tube, see Fig. 2. That portion of the strand drawing down from the controller to wind about the base end of the cop-tube C is beyond the range of traverse of the thread-guide 16, as will be apparent by reference to Fig. 3. Fig. 3 shows the threadguide 16 at the extreme end of its inward traverse or, more specifically, at the limit of its traverse in the right-hand direction, and the yarn drawing through the controller 52 feeds to the surface of the cop-tube C at a point outside the range of the thread-guide to prevent the strand from entering the slot or groove 33 in the guide. The yarn will thus be caused to make a number of turns 11 about the base end of the cop-tube C to provide a reserve length for splicing to another cop in a series; the number of turns in, or the length of, this reserve winding being determined by the setting of the control device.

Referring to Figs. 6, 7 and 8, it has been explained that the ratchet 81 is adjustable rotatively on the disk 68 and by regulating the position of the stop-finger 83 with reference to the release slot '70 in the disk the device may be set to release the yarn-controller after any desired number of strokes of the thread-guide 16. That is to say, the position of the stop-finger 83 with respect to the release slot '70 in the disk 68 determines the extent to which the disk must be moved intermittently by the action of the pawl 94 on the lever 93. It will be understood that the winding-spindle makes several revolutions during one complete traverse of the thread-guide and for the purpose of the present explanation it may be considered that the cop-tube C is revolved six times to one movement of the thread-guide 16 from the inward extreme of its traverse outwardly and back again. As illustrated in Fig. '7 of the present drawings the ratchet 81 is adjusted on the disk 68 in such position that it requires the disk to be turned through the space of seven teeth to carry the slot 70 in the disk into position to release the detentlatch 64 on the controller-member 55. Consequently, with such an adjustment of the device the cop-tube will make six times seven or fortytwo revolutions before the controller is released so that forty-two coils or turns of the yarn will be wound onto the base of the cop-tube to provide the reserve length.

As the initial reserve winding operation proceeds the thread-guide arm 31 is caused to make contact with the hunter 106 on the lower end of the lever 93 at the end of each rearward stroke of the thread-guide. As the thread-guide arm 31 moves away from the bunter 106 on the forward traverse the spring 101 rocks the lever 93 to slide its pawl 94 rearwardly on the ratchet 81 to engage a succeeding tooth thereof. At the next rearward traverse movement of the thread-guide its arm 31 will again rock the lever 93 to advance the ratchet in the same manner, and in this way the disk 68 is intermittently rotated until its slot or opening 70 is turned to a position in register with the opening 66 in the shelf 6'7.

At this juncture the detent-latch 64 is released to swing through the opening 70 in the disk 68 as the member 55 is rocked by its spring '71. The member 55 is rocked downwardly until its stopfinger 69 contacts with the end of the stop-screw '72 and the control-member 52 is thus shifted from its initial position as illustrated in Fig. 3 to the down position as shown in Fig. 4. As the controller 52 is rocked on its pivot the strand y held therein is released from its crotch or guideway 56 in the manner as illustrated in Fig. 4. Upon its release the strand y will be drawn directly from the thread-bail 40 to the surface of the cop-tube C and will assume a position as indicated by the dotted line in Fig. 4. Now, as the threadguide 16 approaches the inward end of its trav-' erse its convex face will ride over the length of yarn y and cause it to be picked up in the groove or slot 33 of the guide. Immediately the guide picks up the yarn in this manner it is traversed thereby back and forth along the length of the cop-tube C to build the cop, cone or other form of package with a warp wind, the yarn being laid in helical turns crossing and recrossing each other to form overlying layers constituting the body of the package.

The operation of the winding machine continues until the package has reached the desired size, whereupon the machine is stopped, usually through the intermediary of sizing mechanism, so-called, as generally provided on machines of the present type. The full package is dotted from the cop-holder 5 and the machine prepared for winding another package in the same manner as hereinabove described. To set the reserve winding device to operate during the initial stages of the winding it only is necessary to swing the control-member 55 back into position to engage its detent-latch 64 in under the disk 68. This operation is performed by placing the finger upon the lever 61 to swing the member 55 upwardly to restore the detent-latch in detained position under the disk 68.

During this operation the finger-lever 61 engages against the rearward end of the arm 92 of the lever 88 to swing the latter to release its pawl 89 from the ratchet 81. The manual operation of the member 55 further causes the curved arm 53 on the controller 52 to engage against the finger 98 on the spring-pawl 94 whereby to release the latter from the ratchet 81. In this manner the ratchet is freed to .permit the spring '76 to return the disk 68 to its initial position with the radial stop-finger 83 bringing up against the side of the lever 93 as shown in Fig. 6. Upon the release of the finger-lever 61 the pawls 89 and 94 are again returned into engagement with the ratchet and the device is ready for another cycle of operations.

It will be observed from the foregoing that the present invention provides a simple and efficient device for effecting the winding of a reserve length of yarn on the cop-tube or other support before the commencement of the winding of the package.

The device can be adjusted to secure any desired length of yarn in the reserve winding in accordance with requirements and when once adjusted will operate repeatedly at the start of each package. The setting of the device merely requires the movement of a single element and the means which controls the yarn to wind a reserve length on the cop-tube is convenient and easy to thread with the same motion of the hand as ordinarily required in preparing the machine to operate without the reserve winding.

The reserve winding device is universally applicable to various types of winding machines without alteration in construction or arrangement of the mechanism thereof. -Moreover it can be readily attached and adjusted in position and is compact in size, efiicient in operation and not liable to breakage or getting out of order.

While the device is herein described and illustrated as embodied in a preferred form of construction, it is to be understood that modifications may be made in the structure and arrangement of its mechanism and in the method of adapting it to winding machines of other types than that herein shown, without departing from the spirit and scope of the invention.
