This invention relates to a method and apparatus for group package forming ofyarn through the medium of which the, yarn, irrespective of size, may be packaged ready to be ldirectly'received in fabric forming" machinery. I

This invention has especial utility'of multiple down-spinningprocesses": and apparatus for throwing lustrous yarn. However, it is not limited in its field of utility'tc'i such use.

For purposes of illustration, the inventionis herein shown and described as arr-improvement in a multiple down spinning'pro'cessand apparatus of the character'i'n which the lustrous yarn is fully thrown and formed into the final package ready, withoutre-drawin'g, coning, or copping, to enter the fabric forming machinery in one continuous uninterrupted ,pera'tion employing a single spinning step.

By employing the improvement of the present invention, both the "silk throwing and p or quill forming may be directly accomplished in one uninterrupted operation in a single: machine.

It is also an, object of "the invention toprovide a method andapparat'us for forming quills or cops whereby the successivestrand layers on the cops formed are effectively interlocked in a manner permitting unwinding in the shuttle 0n weaving without snarling. v

A further object of the invention is top'rovide an improved method and apparatus for forming quills or cops by starting; the winding ateither end of the quill or cop to'be formed and feeding the thread or strand with a traverse which always less than the 'desired len'g'th' of the quill or cop and with a relatively small gain until the other end of the quill or'fcop to'be formed 'is reached, and then rapidly returningthe thread or strand to the first end of the quill or cop and repeating the cycle until the cop is completely formed. I

Other and more detaile'dobjects and advantages will become apparent as the description proceeds. p

The invention will be described by reference to the accompanying drawings wherein:

Figure l is a view in side elevation of a complete quill or cop forming machine unit;

Figure 2 is a front elevation of the machine shown in Figure 1;

Figure 3 is a detailed view showing'a part of the traverse drive mechanism;

Figure 4 is a view taken at a right angle to Figure 3 showing the traverse control cams; and

Figure 5 is a detailed view showing the quill mounting and drive.

Referring to Figure 1, there is a base'frame I on which the entire mechanism is assembled.

A, motor 2 is" centran carried on the frame .I and drives a power belt 3. l The frame I is de-. signed to carry'r'cwsof. complementary units at each" side thereofJ-ffThese are, however, con structed in duplication. Therefore, only a single left-hand unit vis-shown and will be described; The belt 3, drivespulleys 4 and 4. The shaft 5 extends down from pulley 4' and carries a worm 8 at the wwerend thereof which meshes with a worm gea n'lfmounted on a shaft 8 carrying a sprocket fli sprocket chain I0 is trained around the'idrive sprocketi9. The sprocket chain It drives the traverse mechanism, designated broadly A, and also the roller mechanism designated broadly B. Chain 1 0 passesabout sprockets ll, l2, and 13. Sproc'zket H inturndrivesb'evel gears l4 and l5,transmitting p'owertothe shaft l6 suitably carried b the framej'l. Power-is transmitted through shaft [6 for controllingthe movement ofthe traverse mechanism-A, to be later describedin detail. 1

The sprocket-l2 drives bevel gears l7 andflil transmitting? power to shaft 19 for driving the roller mechanism'B. The quill'spindle 20 carries'an enlarged 'hub' 2| normally in driving contact with the belt 3. mounted at its base that-it can be swung-"to'and from contact with the drive belt 3 so that the spindle ofany'um't may be removed fromdrivin'g engagement with the belt without stopping the machine ordisturbing other units.

Coming'now-to a description of the mountings for the swifts-o'r reels for the skeins, there-is rigidly secured to the upper end of the frame I a mainsupporting arm 22. The arm 22 carries at its free end a central hub 23; The hub 23in turn carries-four arms 24, each carrying at-its free end a swift or reel 25. Each reel 25 is-coristructed to receive a skein. The central hub 23 is rotatably carried by the arm 22 so thatany swift or reel-=25 may be brought within reach of the operator for tying broken strands arreplacing skeins. A locking mechanism for-holding the-hub 23 in anygiven p'osition'of adjustment with respect to the arm 22 is provided and includes the latch detent 26 extending through arm 22 andadaptedto engage the hub 23.

The manner-of taking off the strands from the individual skeinsis such that the hub 23 can be moved toand held in? any position of adjust:

ment without interfering with the operationlof themachine, The end of the strand from; each skein is threaded through a porcelain eye ;,28

transversely of the hub 23 to the single ,por celain condensing guide 29 carried by thefarm 22' o ffthe'next adjacent unit. From thelguide '29 the condensed strand, designated; 30, is passed down to" the ron r mechanism '3' (see 'Figu're'2ll carried byhub 23, and each strand then vpasses 1 e m w i h? roller mecha sm B, a min 2. The pindle 2g esupporting bracket arm 3| is secured to the upper end of the base frame I and-supports the entire roller mechanism. The shaft I 9 passes longitudinally of the arm 3! to drive the roller 32 through suitable bevel gears.

A stop motion is provided, and the arrangement is such that, when the electromagnet 33 is energized through the closing of a circuit due to the breaking of a strand, the armature is attracted and causes disengagement of the roller driving gears, allowing the roller 32 to stop.

Passing now to the means for disconnecting the package or quill carrying spindle 28 from the driving belt 3, it will be noted that a latch bar 34 is provided at its outer end with an aperture through which extends a spindle releasing rod 35. The rod 35 is pivotally mounted at its lower end on a pivot 36, about which it is moved by the latch arm 34 when released by energization of magnet 33.

As shown in Figure 2, the spindle releasing rod 35 extends behind a finger 31 carried by the mounting 38 for spindle 28. It will be observed that the mounting 38 is journaled upon a vertical fit pivot 39 which is eccentric to the axis of spindle 20, the vertical pivot 39 being supported by a fixed bracket 48 carried by the frame I. There is also carried by the bracket 40 a fixed brake shoe 4 I.

The action is as follows: The mounting 38 carrying the spindle 28 is normally urged toward the belt 3 by a coil spring to insure driving engagement between belt 3 and spindle hub 2|. Now, when magnet 33 causes the release of latch bar 34, the latter, due to the action of a spring, forces spindle releasing rod 35 outwardly against the finger 31 to swing the spindle mounting 38 about the eccentric pivot 39 and move the spindle hub 2| from engagement with belt 3 and into engagement with fixed brake shoe 4| to stop the spindle.

Before leaving the spindle releasing rod 35, it will be further observed that when this rod is moved to release spindle hub 2| from driving eni gagement with belt 3, it also opens, through the medium of rod 42, contacts 43 in series with ma net 33 to de-energize the same. The spindle releasing rod 35 remains in its released position, until manually restored by re-engagement of a latch on bar 34, to maintain the roller 32 and the spindle 29 inoperative.

Returning to the roller 32, the composite strand 3|] coming from the porcelain guide eye 29 is drawn through a porcelain eye 44 supported by the latch bar 34 in a position directly above the left-hand end of roller 32, as viewed from the front. A porcelain guide 45 is mounted immediately above the roller 32. The roller 32 is provided on its circumference with three flat-bottomed grooves or channels separated by square shouldered flanges.

The thread 38 leaves the eye 44, enters the groove adjacent the left side of roller 32, is carried once around roller 32 in this groove, thence passes over porcelain guide 45 into the next groove and once again around the roller 32, thence passing again over porcelain guide 45 to the next groove and thence through eye 46 and on to the traverse mechanism hereinafter described. The thread is caused to roll axially of the roller 32 in the grooves thereon, whereby the yarn delivered to the traverse mechanism'is partially twisted. The flat-bottomed grooves together with the square shouldered flanges therebetween are particularly advantageous in giving a tightly twisted yarn and preventing snarling and entangling of the yarn upon the roller.

The improved traverse operating and control mechanism by which the novel method of package forming is accomplished will now be described. Returning to the driven shaft IS, a heart-shaped cam 41 is carried thereby, which oscillates an arm 48 loosely journaled upon a rocker shaft 49 extending parallel to shaft l6.

The arm 48 carries a cam follower roller 59 which rides on cam 41 to cause oscillation of arm 48. The arm 48 also carries a shaft 5| journaled therein, on one end of which is fixed a half-heart cam 52 and on the other end of which is carried a worm gear 53. The worm gear 53 and halfheart cam 52 are driven from shaft I6 by means of sprocket 54 on shaft l6, chain 55, and the sprocket 56 mounted on rotating sleeve 51 loosely journaled upon shaft 49. The sleeve 5'1 carries at its opposite end a worm gear 58 which drives a worm gear 59 upon a shaft 68 extending at right angles to shaft 49 and journaled in a bearing 6| carried by rocker arm 48. The shaft 68 carries at its opposite end a worm 62 which drives gear 53 and half-heart cam 52.

The shaft 49 has afiixed thereto a rocker arm 63 which carries at its free end a cam follower roller 64 riding upon the half-heart cam 52. Shaft 49 carries at its outer end a bell-crank lever 65 (see Figure 2), the horizontal arm of which carries a roller I02 at its free end. The roller I02 engages a thrust plate 6'! on the lower end of the traverse reciprocating rod 68 mounted in a guide bearing 69, supported on frame I and carrying horizontal ring supporting rods 18 at its upper end. The rods H1 are common to a plurality of units and carry the ring H. The vertical arm of bell-crank 65 is pivotally connected to a rod 12 which operates bell-cranks similar to 65, which cooperate to actuate ring-supporting rods 10. The ring II is provided with a suitable traveler that receives and guides the thread 30 as it is spun and wound to form a cop or quill on the spindle 20.

The operation of the traverse is as follows: The heart cam 47 directly driven by shaft 16 rotates at a relatively rapid speed and produces, through arms 48, 63, and 65, traverse movement of uniform amplitude. The amplitude of the uniform traverse is controlled by the size of cam 41 and is intentionally always less than the desired length of quill or cop to be formed. The half-heart cam 52 controls the traverse gain on the quill. 41. through this may be varied if desired. On each rotation of cam 41 there is but a small movement of cam 52 which, translated to the traverse, causes it to gain on each rotation of cam 41 proportioned to the movement and pitch of the cam 52.

The cam 52 is so constructed that the cam follower 64rides, during seven-eighths of each revolution thereof, on the curved face of the cam and returns to the point of beginning in but oneeighth of a revolution of cam 52. It will thus be observed that after the total gain provided by the curved surface of cam 52 has been effected, there is a quick return to the point of beginning. Due to the form of cam follower 64, the return is effected in much less than one-eighth of a revolution of cam 52. Translated to the quill or cop the winding commences, for example, at the bottom, the upward traverse is uniform. The downward traverse is also uniform but is always Cam 52 moves much slower than cam A ratio of 15 to 1 is found satisfactory, al-

ing a plurality of overlapping traverses.

shorter than the upward traverse! When the'topmost traverse is reached, the ring is rapidly returned to the bottom of the quill and the cycle repeated. The winding may be commenced at the top of the cone or quill and the action reversed by merely reversing the half heart cam 52.

The cop or quill isbuilt upfrom the bottom by successive layers of thread, each layer compris- This results in the formation of a cop or quill having a very effective interlocking wind and one which will unwind inthe shuttle on weaving without snarling.

No electrical diagram of the circuit for the electromagnet 33 of the stop mechanism is shown, it being obvious that this circuit is closed upon the breaking of any one of the strands coming from the skeins on reels 25 through the action of the rod carrying the porcelain eye 28 and that the circuit is broken'by the spindle release rod when the stop mechanism has been actuated.

In accordance with the present invention, it is possible to throw silk and form crepe silk or rayon cops or quills in one uninterrupted operation with but one twisting and winding operation. This has never, to my knowledge, been heretofore accomplished. Crepe silk or rayon requires around sixty-five twists per linear inch, and no machine hasheretofore been devised for both throwing the silk and giving a cop or quill of thread of this character directly ready for the shuttle of the loom. According to this invention, the quill spindle is driven at a very high speed approximating 15,000 R. P. M. With this permissible speed and the method of twisting and cop forming employed, I am able to turn out crepe silk or rayon quills or cops in one operation, taking the rovings from the skeins and producing finished headless packages ready, without re-drawing, coning, or copping, to directly enter fabric forming machinery.

While the invention has been herein illustrated and described as incorporated in a multiple ring spinning process and apparatus, it is to be understood that the group package forming features of the invention may be employed wherever found desirable and need not be associated with ring spinning. The group packaging of yarn employing the traverse mechanism of the present invention is exceedingly practicable in packaging yarns of various sizes. When employing the present invention, it is not necessary to change the builder ratio or rate of movement of the traverse with changes in yarn size.

In group package forming as presently practiced, it is necessary to change the ratio of the builder motion depending upon the size of the yarn being packaged. This is entirely obviated by the present group package forming process and apparatus which is applicable to any yarn size.
