29 Claims.

This application is a division of my copending application Serial No. 674,568, filed June 6, 1933.

This invention relates to an improved apparatus for throwing silk or rayon and for forming cops or quills and is especially well adapted for making silk and rayon crepe cops or quills. While machines have heretofore been devised for doubling and. twisting yarn such as exemplified by the patent to Allen No. 775,550, none of the prior art methods or machines have been adapted for use in quilling silk and. rayon, more especially silk crepe.

It is the purpose of the present invention to provide an economical apparatus for both throwing silk and forming quills and to provide for forming quills of crepe silk ready for the shuttle which will not snarl in weaving.

It is conventional practice in. throwing silk and rayon crepe and forming rayon and silk crepe cops or quills to employ five separate operations which render the same laborious and expensive.

By the instant invention, both the silk throwing and cop or quill forming may be directly accomplished in one uninterrupted operation in a single machine.

It is also an object of this invention to provide, in a concurrent silk throwing and quill or cop forming machine, suitable apparatus for effecting eflicient control of the thread supply to prevent overrunning of the supply holders.

Still another object of this invention is to provide, in a concurrent silk throwing and quill or cop forming machine, suitable apparatus for effecting complete control of the rotation of the various thread supplies and spun yarn holders, as a result of slack in or breakage of any of the individual thread strands.

A still further object of the invention is to provide a form of drive for the various spindles, thread feeding means, and traverse mechanism of a multi-unit spinning machine which will assure complete synchronization of the speed of operation of all of these various instrumentalities during all periods of operation of the machine.

It is a further object to provide a novel mounting for the skein swifts or reels and to provide other specific improvements in the doubling and winding mechanism.

Other and more detailed objects and advantages will become apparent as the description proceeds.

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

Figure 11 is a fragmentary detailed view taken at a right angle to Figure 10.

Referring to Figure 1, there is a base frame I on which the entire mechanism is assembled. A motor 2 is centrally carried on the frame I and drives a power belt 3. The frame I is designed to carry rows of complementary units at each side thereof. These are, however, constructed in duplication. Therefore, only a single left-hand unit is shown and will be described. The belt 3 drives pulleys 4 and 4. The shaft 5 extends down from pulley 4' and carries a worm 6 at the lower end thereof which meshes with a worm gear I mounted on a shaft 8 carrying a sprocket 9. A sprocket chain 10 is trained around the 3 drive sprocket 9. The sprocket chain In drives the traverse mechanism, designated broadly A, and also the roller mechanism designated broadly B. Chain l0 passes about sprockets ll, l2, and I 3. Sprocket l l in turn drives bevel gears l4 and I5, transmitting power to shaft l6 suitably carried by the frame I. Power is transmitted through shaft l6 for controlling the movement of the traverse mechanism A, to be later described in detail.

The sprocket l2 drives bevel gears I1 and I8 transmitting power to shaft IQ for driving the roller mechanism B. The quill spindle carries an enlarged hub 2| normally in driving contact with the belt 3. The spindle 20 is so mounted at its base that it can be swung to and from contact with the drive belt 3 so that the spindle of any unit may be removed from driving engagement with the belt without stopping the machine or disturbing other units.

Coming now to a description of the mountings for the swifts or reels for the skeins, there is rigidly secured. to the upper end of the frame I a main supporting arm 22. The arm 22 carries at its free end a central hub 23. The hub 23 in turn carries four arms 24, each carrying at its free end a swift or reel 25. Each reel 25 is constructed to receive a skein. The central hub 23 is rotatably carried by the arm 22 so that any swift or reel 25 may be brought within reach of the operator for tying broken strands or replacing skeins. ing the hub 23 in any given position of adjustment with respect to the arm 22 is provided and includes the latch detent 26 extending through arm 22 and adapted to be selectively projected into the holes 21 (see Figure 10) of the hub 23.

The manner of taking off the strands from the individual skeins is such that the hub 23 can be moved to and held in any position of adjustment without interfering with the operation of the machine. The end of the strand from each skein is threaded through a porcelain eye 28 carried by hub 23, and each strand then passes transversely of the hub 23 to the single porcelain condensing guide 29 carried by the arm 22' of the next adjacent unit. Fromthe guide 29 the condensed strand, designated 30, is passed down to the roller mechanism B (see Figure 2).

Due to the extreme difliculty of providing perfectly balanced reels or swifts and, further, to the uneven moisture content at different portions of the skeins mounted thereon, it becomes necessary to provide an individual braking mechanism for each swift or reel to insure a uniform tension of the separate strands taken off from the several skeins.

The braking mechanism for each swift or reel is identical and only one will be described. Each swift 25 is provided with a braking surface 3| (see Figure 10). A rubber brake shoe 32 is adapted to bear against the surface 3|. The shoe 32 is carried by a wire rod 33 pivotally supported on an insulating bracket 34 carried by the swift supporting arm 24. A coil spring 35 is connected to the rod 33 and tensioned to normally urge the shoe 32 against the surface 3|. The opposite end of the rod 33 (see Figure 11) is bent outwardly and passed through a guide loop 36 and terminates in a right angularly bent end 31. Now the porcelain eye 28 is carried by a wire rod 38 pivotally mounted in an insulated bracket 33 carried by the central hub 23. A spring 48 normally urges the rod 38 and porcelain eye 28 inwardly toward the hub 23.

The bent end 31 of brake rod 33 extends just outside the rod 38 carrying the eye 28. The arrangement is such that when a strand is being pulled through the eye 28 under normal tension, the eye 28 is pulled outwardly against the tension of spring 48 and in turn pulls the lower end of rod 33 out by virtue of its bent end 31. This causes rod 33 to have pivotal movement on the bracket 34 against the tension of spring 35 and thus release the brake shoe 32.

When the swift or reel rotates too fast, due to any unbalanced condition, it tends to cause a slack in the strand and destroys the normal, tension. When this happens, the spring 35 immediately applies brake shoe 32 tothe swift and slows it down until normal tension of the strand is restored.

At this point it is well to note that the arm 38 carrying eye 28 is also adapted, when a strand breaks, to be forced by spring 40 against contact A locking mechanism for hold member 4| to close a circuit for controlling a stop mechanism to be hereinafter described in more detail.

Coming now to the roller mechanism B, a main supporting bracket arm 42 is secured to the upper end of the base frame I and supports the entire roller mechanism. The shaft l9 passes longitudinally of the arm 42 to drive the roller 43 through bevel gears 44 and 45 (see Figures and 6). The supporting arm 42 has fixed thereto a right angularly disposed bar 46. At

, the lower end of bar 46 there is aifixed an extension arm 41 in parallelism with the arm 42. Pivotally mounted on the free end of arm 41 is a swinging bar 48. The swinging bar 48 is provided with a bearing 49 for the shaft 58 carrying the roller 43 and the bevel gear 45. The swinging bar 48 is biased away from the bevel gear 44 on shaft M3 by a coil spring 5| surrounding the pivot 52 upon which the bar 48 is journaled.

The swinging bar 48 is normally held in position with the gear 45 in mesh with bevel gear 44 against the tension of spring 5| by a latch bar 53. The latch bar 53 is provided with a slot 54 through which a bolt 55 extends for attaching the latch bar 53 to the swinging bar 48.

Mounted on the upper end of bar 46 (see Figure 8) is a bracket 56, which carries a casting 51 pivoted at 58 and adapted in normal position to cooperate with a projection 59 on the end of latch bar 53 to hold the swinging bar 48 in position with gears 44 and 45 in mesh. The casting 51 also carries an electromagnet 68 and a pivoted armature 5|. The armature 6| pivoted at 62 carries a trigger finger 63 adapted, when the magnet 68 is energized, to engage a projection 64 carried by the gear 44 on shaft l9.

The arrangement is such that, when the electromagnet 68 is energized through the closing of a circuit due to the breaking of a strand, the armature 6| is attracted and causes the trigger 53 to move into the path of a projection 64 on gear 44.

The projection 64 moves the trigger 63 and rocks the casting 51 about the axis 58 to release the latch bar 53. Release of latch bar 53 allows spring 5| to swing the arm 48 to cause disengagement of bevel gears 44 and 45 and allow roller 43 to stop.

Passing now to the means for disconnecting the quill carrying spindle 28 from the driving belt 3, it will be noted that the latch bar 53 is provided at its outer end with an aperture 65 through which extends a spindle releasing rod 83. The rod 86 is pivotally mounted at its lower end on a pivot 31, about which it is moved by the latch arm 53 when swinging arm 48 is released and moved by the spring 5|.

As shown in Figure 2, the spindle releasing rod 56 extends behind a finger 68 carried by the mounting 38 for spindle 28. It will be observed that the mounting 69 is journaled upon a vertical pivot 18 which is eccentric to the axis of spindle 28, the vertical pivot 18 being supported by a fixed bracket 1| carried by the frame I. There is also carried by the bracket 1| a fixed brake shoe 12 (see Figures 2 and 9).

The action is as follows: The mounting 69 carrying the spindle 28 is normally urged toward the belt 3 by a coil spring 13 (see Figure 9) to insure driving engagement between belt 3 and spindle hub 2|. Now, when magnet 60 (Figure 5) causes the release of latch bar 53, the latter, due to the action of spring 5|, forces spindle releasing rod 66 outwardly against the finger 68 to swing the spindle mounting 69 about the eccentric pivot I and move the spindle hub 2I from engagement with belt 3 and into engagement with fixed brake shoe I2 to stop the spindle.

Before leaving the spindle releasing rod 66, it will be further observed that when this rod is moved to release spindle hub 2| from driving engagement with belt 3, it also opens, through the medium of rod I4, contacts 15 in series with magnet 08 to de -energize the same. The swinging arm 48 and spindle releasing rod 66 remain in their released position, until manually restored by re-engagement of the latch 59 on bar 53 with the pivoted casting 51, to maintain the roller 43 and the spindle 20 inoperative.

Returning to the roller 43, the composite strand 30 coming from the porcelain guide eye 29 is drawn through a porcelain eye I6 supported by the latch bar 53 in a position directly above the left-hand end of roller 43, as viewed from the front. The bolt 55 carries a porcelain guide Tl immediately above the roller 43. The roller 43, which is mounted to rotate with shaft 50 and bevel gear 45, is provided on its circumference with three fiat-bottomed grooves or channels I8, 19, and 80 separated by square shouldered flanges 8I.

The thread 30 leaves the eye I6, enters the groove I8 adjacent the left side thereof, is carried once around roller 43 in groove I8, thence passes over porcelain guide 11 into the groove I9 and once again around the roller 43 in groove 19, and thence passes again over porcelain guide 71 to groove 80 to porcelain eye 82 and on to the traverse mechanism hereinafter described. The thread is caused to roll axially of the roller 43 in the grooves thereon, whereby the thread delivered to the traverse mechanism is partially twisted. The flat-bottomed grooves I8, I9, and 30, together with the square shouldered flanges M, are particularly advantageous in giving a tightly twisted thread and preventing snarling and entangling of the thread upon the roller.

The improved traverse operating and control mechanism by which applicants novel method of quill forming is accomplished will now be described. Returning to the driven shaft IS, a

heart-shaped cam 83 is carried thereby, which oscillates an arm 84 loosely journaled upon a rocker shaft 85 extending parallel to shaft I6.

The arm 84 carries a cam follower roller 86 which rides on cam 83 to cause oscillationof arm 84. The arm 84 also carries a shaft 81 journaled therein, on one end of which is fixed a half-heart cam 88 and on the other end of which is carried a. worm gear 89. The worm gear 89 and halfheart cam 88 are driven from shaft I6 by means of sprocket 90 on shaft I6, chain 9|, and the sprocket 92 mounted on rotating sleeve 93 loosely journaled upon shaft 85. The sleeve 93 carries at its opposite end a worm gear 94 which drives a worm gear 95 upon a shaft 96 extending at right angles to shaft 85 and journaled in a bearing 97 carried by rocker arm 84. The shaft 96 carries at its opposite end a worm 98 which drives gear 89 and half-heart cam 88.

The shaft 35 has affixed thereto a rocker arm 09 which carries at its free end a cam follower roller I00 riding upon the half-heart cam 88. Shaft 85 carries at its outer end a bell-crank lever IOI (see Figure 2), the horizontal arm of which carries a roller I02 at its free end. The roller I02 engages a thrust plate I03 on the lower end of the traverse reciprocating rod I04 mounted in a guide bearing I05, supported on frame I and carrying horizontal ring supporting rods I06 at its upper end. The rods I06 are common to a plurality of units and carry the ring I01. The vertical arm of bell-crank IOI is pivotally connected to a rod I08 which operates bell-cranks similar to IOI, which are individual to other units and cooperate to actuate ringsupporting rods I08. The ring I01 receives and guides the thread 30 as it is wound to form a cop or quill on the spindle 20.

The operation of the traverse is as follows: The heart cam 83 directly driven by shaft I6 rotates at a relatively rapid speed and produces, through arms 84, 99, and I09, traverse movement of uniform amplitude. The amplitude of the uniform traverse is controlled by the size of cam 83 and is intentionally always less than the desired length of quill or cop to be formed. The halfheart cam 88 controls the" traverse gain on the quill. Cam 88 moves much slower than cam. 83. A ratio of 15 to 1 is found satisfactory, although this may be varied if desired. On each rotation of cam 83 there is but a small movement of cam 88 which, translated to the traverse, causes it to gain on each rotation of cam 83 proportioned to the movement and pitch of the cam 88.

The cam 88 is so constructed that the cam follower I00 rides, 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 88. It will thus be observed that after the total gain provided by the curved surface of cam 88 has been effected, there is a quick return to the point of beginning. Due to the form of cam follower I00, the return is effected in much less than one-eighth of a revolution of cam 88. Translated to the quill or cop which the winding commences at the bottom, the upward traverse is uniform. The downward traverse is also uniform but is always shorter than the upward traverse. When the topmost traverse is reached, the thread is rapidly returned to the bottom of the quill and the cycle repeated.

The cop or quill is built up from the bottom by successive layers of thread, each layer comprising a plurality of overlapping traverses. This results in the formation of a cop or quill having a very effective interlocking wind and one which will unwind in the shuttle on weaving without snarling. This feature of the invention is of great value, and- I amv not to be limited to the precise form of mechanical movement disclosed, by which this advantageous result is obtained, since other mechanism than that shown may be employed.

No electrical diagram of the circuit for the electromagnet 80 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 38 carrying the porcelain eye 28, as heretofore described, and that the circuit is broken by the spindle release rod 68 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 has heretofore 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 E. 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 COPS.

The foregoing description is illustrative only, the invention being limited and restricted only by the scope of the appended claims.
