3 c aims; (or. wh e-153) This invention relates to the winding of yarn on tubes, cones or other yarn carriers and more particularly it relates to on automatically onersted means for winding a, reserve length of yarn on the end of the carrier before winding the yarn This application is a division of my prior application Serial No. 506,245, filed October 14, 1943.

It has been found advantageous to have a reserve length of yarn wound on the carriers of yarn packages to serve as o. transfer tail where the yern is used on warping or hitting machines, but where the last operation of preparing the yarn package comprises a twisting operation, thereis usually at the beginning .of the winding a. short length of the yarn which is not uniform ly twisted. lt-is, therefore, an object of this invention to provide automatic means for winding on the end of the yum carrier ewe-etc toll of sufflcient length to include all the nonuniiormly twisted yum ut'the start of the winding prior to winding theusual transfer tail of reserve yarn, the two groups of turns oi the yarn being spaced from each other and from the yorn package on the carrier.

In the drawings, the invention is shown opplieezl to o winding machine or known construction, only such ports of the winding machine being shown as are necessary to illustrate the appliestion of the invention thereto. at the winding- :mschine there is shown the driving rollers l mounted at opposite sides of the machine on shafts 2 supported in suitable bearings (not shown) roll l and during the winding of the body of the,

package, the yarn is guided by s. yum guide it mounted upon the traverse bar 92 which is reciprocoted throughout the winding omretion so as to distribute the yarn on the tube.

To receive the waste and trensfer turns of the yarn, each tubet is formed with'spsced grooves to and to at one end or the'tube and theysrn is guided to the grooves oi'esch tube by means of a. yarn guide it mounted on other it which is supported by spaced links lit pivotslly connected to the bar it and a berth carried by the machine frame, A spring 22 connected to an end of the bar it and to the machine .rrome biases the-bar it to a position as shown in Figure twhile .o. pin to mounted in on end of s lever u it and engaging between pins 25 and 2? fixed in the-bur it controlsthe movement or the bezit.

The lever arm 26 is one arm of s substantially "i-shoped' lever pivotal-1y mounted as st 2%, on the bed plate :3 and having an arm 2t extending to the opposite side of the machine and provided witho, pin 8t engaging between plus it end 2'! fixed in o bar it to control the operation. of the some simultaneously with the operation of the bar it, the bar it being mounted similarly to the on upwardly projecting can: follower t2 positioned inwardly. from the pins ti and t3.

The com follower 32 is positioned to engage a com to mounted for rotation about a bolt 38 fixed in the bed plate l. A spring 2! coiled about a hub attached to the cement! having one end engaged with the base plate 4 and its other end engaged with the cum M, opposes the rotation of the cam in a clockwise direction. The com 38 is a flat circular disk having an irregular sector-like portion cut away and providing a circular cam face 3M extending approximately 210 and a short com face 342 of less redius than the larger cam free Ml. Bolts 33 and springs 39 surrounding the bolts yieldingly secure a stop member 23 'to the cam 34 where the portion hasbeencut away, the member 23 projecting radially ot-the cam it to engage with the cam follower 32.

' which is pivots-11v groove to.

; Becuredtotheuppersurfaceofthecamdisk 84 is a ratchet wheel Ill arranged to be engaged for operation in a clockwise direction by a pawl 42 pivotally mounted at an end mounted on the bolt 36, supporting the cam 84. A spring 6 engaging the pawl 42 and its pivotal support biases the pawl to engage'the ratchet wheel 40.

The opposite end of the lever 48 is engaged by a lever arm 48 fixed on a shaft 50 suitably journalled in the machine frame. Also fixed on theshaft Bil is a lever arm 52 positioned to engage a cam 54 fixed on the roller shaft 2. A spring 58 secured to the upperend of the lever 48 and the adjacent and of the lever ll holds these levers in engagement while a spring 58 secured to the lever 52 and to the machine frame tends to hold the lever 52 in engagement with the cam 54. A looking dog 80 plvotally mounted on the bed plate 4 is biased by a spring 82 to engage with the ratchet wheel 40 and prevent rotation of the ratchet wheel and cam 3Q in a counter-clockwise direction by the spring 2!. Mounted on the dog 60 is an adjustable abutment 64 positioned in the plane of the lever arm 30.

When the mechanism is operating to wind the wastetail on the tube and the parts are positioned as shown'in Figure 1, the follower 32 on lever 30 bears against the cam face 3 at or adjacent the stop member 23, pawl 42 is positioned to engage ratchet wheel 40, lever 52 bears against cam 54v and pin 24 on lever 26 bears againstpin 25 and holds bar it pressedto the right, as seen in Figures 1 and 3, so that the yarn guides M are allned with the outer grooves 60. on the tubes 8 and the bar it is raised by the links l8 against the actionof spring 22. With the shaft 2 operated to rotate rolls l and tubes 6 to wind the yarn in the outer groove ta of each tube 6, rotation ofcarn 54 operates lever 52, once for each revolution of shaft 2 and, through shaft til, lever 48 and lever operates the pawl IM to rotate the ratchet wheel 48 step by step in a clockwise direction and shift the cam 34 against the action of spring 2|. The winding of the yarn in the outer groove 6a. continues as the cam 34 is moved around-step by step until the follower 32 passes from the cam face 3. As the follower 32 passes from the cam face 8", spring 22 shifts the bar It to move the yarn guide I! to the left until it is alined with the inner groove to and at the same: time, through the engagement of pin 25 with pin 24, shifts the levers 26, 30 so as to bring the follower 32 into contact A with the cam face 342. Cam face 342 limits the movement of the levers 2B, 30 and bar lfiand holds the yarn guide It alined with the inner Continued operation of the shaft 2 causes the yarn to be wound in the groove 6b and continues the stepping around of the cam 34 until the cam into the cutaway portion of the cam 34. This movement of lever 30 brings pin 33 against lever 44, causing lever 44 to rotate on the bolt 36 and,

through'spring 58, to rotate lever 48, shaft 50 and lever 52, lifting lever 52 from the cam 54 against the action of spring 58 and preventing further operation of the lever "by the cam 94. Looking .aaeaaor of a lever 4t Throughout the operation of themachine, the traverse bar l2 has been reclprocated, carrying with it the yarn guide Id. The second movement to the left of the bar it by the spring 22 shifts the yarn guide 14 from the groove to and, at the same time, lowers the bar It and yarn guide it as the supporting links it pivot about their connection to the fixed bar 20. This movement of the yarn guide H positions the yarn to be engaged by the yarn guide M, the yarn passing up the inclined side of yarn guide Ill and being retained'in the slot thereof. Continued movement of the yarn guide It thereupon distributes the yarn upon the tube 6 during the winding of the package in the usual manner.

Upon replacement of filled tubes with empty tubes, the lovers 26, 3 are operated by means-of handle 86. rotating the lever about the pivot 28 and shifting bar it to the right to raise the bar It and aline theyarn guide H with the groove to.

locking dog 80 and dlsengages the dog 60 from the ratchet wheel Q9. Disengagement of the dog Bil from the ratchet wheel permits the spring 2| to rotate the cam 3t and ratchet wheel 80 counterclockwise until the stop member 23 on the cam 36 engages the cam follower 32, thus causing the cam 83 to be returned to its starting position.

stopmember 2i3.and prevent damage to the various parts. The parts are now in starting position and upon placing the yarn in the yarn guide I i and securing the end of the yarn so it will wind upon the tube ii, the cycle of operations is repeated.

The return of the cam 34 to itsinitial position for the start of each winding operation insures uniform lengths of the waste and transfer tails 5 being wound at each operation. When the yarn package is used, severing the yarn. between the waste and transfer tails insures transfer tails of uniform length and uniform twist' throughout.

The completed package of the present invention 50 is shown in Figure '7 and comprises the waste tail A in groove 64:, the transfer tall 3 in groove 8h and the main winding C on the body of the tube t. The waste tail has varying twist, whereas the transfer tail B has the full twist throughout its gs-length.

What is claimed is:- r 1. The combination of a yarn carrier, a yarn package and transfer and waste tails on the carrler, said transfer and waste tails being spaced gofromthe yarn package and from each other. face 342 passes from beneath the follower 32 per-'- mitting the spring 22 to shift. the bar It further 1 to the left and to cause the follower 32 to move 2. The combination of a yarn carrier, a yarn package and transfer and waste tails on the carrier, said transfer and waste tails beingspaced from the yarn package and from each other, all 05 of the yarn in the transfer tail having substanf tially the same twist as that in the package.
