10 Claims.

This invention relates to an improved process and 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,"v 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 process and 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.

Itis conventional practice in throwing silk and rayon crepe and forming rayon and silk crepe cops or quills to employ five separate operations Y which renders 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 avsingle machine.

It is also an object of the invention to provide a method and apparatus for concurrently throwing silk and forming quills or cops whereby the successive strand layers on the cops formed are eectively interlocked in a manner permitting unwinding in the shuttle on weaving without snai-ling.

A further object of the invention is to provide an improved method and apparatus for forming quills-or cops by starting the Winding at one end` of the quill or cop to be formed and feeding the 35 thread or strand with a traverse which is always less than the desired length of the quill or cop and with a relatively smallgain until the other end of the quill or cop to be formed is reached and then rapidly returning the thread or strand 40 to the first end of the quill or cop and repeating the'cycle until the cop is completely formed.

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 detail objects and advantages will become apparent as the description proceeds.

The invention will be described by referenceto the accompanying drawings wherein:

Fig. 10 is an enlarged detail view showing the central skein carrying drum and one skein carrying arm; y

Fig. 11 is a fragmentary detail view taken at a right angle to Figure 10. p

Referring to Figure'l 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 i and 3'; shaft 5 extends down from pulley 4 and carries a worm nat the lower end thereof which meshes with a Worm gear i mounted on a shaft 8 carrying a sprocket 9.

A sprocket chain I is trained around the drive sprocket 9. The sprocket chain IG drives the traverse mechanismdesignated broadly A and also the roller mechanism designated broadly B.

Chain IIJ passes about sprockets II i 2 and I3. Sprocket II in turn drives bevel gears IB and i5, transmitting power to shaft I6 suitably carried by the frame I. Power is transmitted through shaft I6 for controlling the movement of the traverse mechanism A to be later described in detail.

The sprocket I2 drives bevel gears i1 and iv transmitting power toV shaft I 9 for driving the roller mechanism B.

The quill spindle 20 carries an enlarged hub 2| normally in driving contact with` the belt 3. The spindle 2li 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. 1

Coming now to a description of the mountings for the swifts or reels for the skeins, there is chanism 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. 'I'he 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. A locking mechanism for holding 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 intothe holes 21 (see Fig. 10') of the hub 23.

The manner of taking oii the strands from the individual skeins yis. 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 23 carried by hub 23; 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. From the guide 29 the condensed strand designated 33 is passed down to theroller mechanism B. (See Fig. 2.)

Due tothe extreme dimculty 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 orreel to insure a uniform tension of the separate strands taken on from the several skeins.

'I'he 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 Fig. 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|. 'I'he opposite end of the rod 33 (see Fig. 11) is bent outwardly and passed through a guide loop 33 and terminates in a right angularly bent end 31. Now the porcelain eye 23 is carried by a wire rod 33 pivotally mounted in an insulated bracket 39 carried by the central hub 23. A spring 43 normally urges the rod 39 and porcelain eye 23 inwardly toward the hub 23. j

. The bent end 31 of brake rod 33 extends just outside the rod 33 carrying the eye 23. The arrangement is such that when a strand is being pulled through the eye 23 under normal tension, the-eye 23 is pulled outwardly against the tension of spring 43 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 releases the brake shoe 32. Now. 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 appliesbrake shoe 32 tothe swift and slows it down until normal tension of the strand is restored.

- Atthis point, it is well to note that the arm 33 carrying eye 23 is also adapted, when a strand breaks, to be forcedby spring 4 3 against contact member 4| t0 close a circuit for a vstop mechanism to be hereinafter described in more detail.

Coming now to the roller mechanism B, a main supporting bracket arm 42 is secured to theupper end of the base frame I and supports the entire 5 roller mechanism. The shaft I9 passes longitudinally oi the arm 42 to drive the roller 43 through bevel gears 44 and 45 (see Figs. 5 and 6). The sup-- porting arm 42 has fixed thereto a right angularly disposed bar 4,6. At the lower end of bar 46 there is aillxed an extension arm 41 in parallelism with the arm 42. Pivota'lly mounted on the free end of arm 41 is a swinging bar 43. The swinging bar 43 is provided with a bearing 49 for the shaft 53. carrying the roller 43 and the bevel gear 45. The swinging bar 43 is biased away from the bevel gear 44 on shaft I9 by a coil spring 5| surrounding the pivot 52 upon which the bar 43 is journaled.

The swinging bar 43 is normally held in posi` tion with the gear 45 in mesh with bevel gear 44 against the tension of spring 5I 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 43.

Mounted on the upper end of bar 46 (see Fig. 8) is a bracket 56 which carries a casting 51, pivoted at 53 and adapted in normal position to cooperate with a projection 53 on the end of latch bar 53 to hold the swinging bar 48 in position with gears 44 and 45 in mesh. 'I'he casting 51 also carries an electromagnet 60 and a pivoted armature 6|. The armature 6| pivoted at 62 carries a trigger finger 63 adapted when the magnet 63 is energized to engage a projection 64 carried by the gear 44 on. shaft i3.

' 'I'he arrangement is such that when the electromagnet 33 is energized through the closing of` a circuit due to the breaking of a strand, the arma' ture 3| is attracted and causes the trigger 63 to move into the path of a projection 64 on gear 44.

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

Passing now to the means for disconnecting the quill'f carrying spindle 23 from the driving belt 3. it will be noted that the latch bar 53 is provided at its outer end with an aperture 35 through which extends a spindle releasing rod 36. 'I'he rod 33 is pivotally mounted at its lower end on a pivot 3`|v about which it is moved lby the latch arm 53 when lswinging arm 43 is released and moved by the spring 5|.

As shown in Figure 2, the spindle releasing rod 33 extends behind a finger 63 carried by the mounting 39 for spindle 20. It will be observed that the mounting. is journaled upon a vertical pivot 13 which is eccentric to the axis of spindle 23, the vertical pivot 13 being supported by a iixed bracket 1| carried `by the frame There is also carried by the bracket 1| a fixed" brake shoe 12. (See Figs. 2 and 9.) o5

The action is as follows: 'I'he mounting 39 carrying the spindle23 isnormally urged toward the belt 3 by a coil spring 13 (see Fig. 9) to in sure driving engagement betweenv belt 3 and spindle hub 2|'. Now, when magnet 63 (Fig. 5) 7o causes the release of latch bar 53, the latter, due to the action of spring 5I, forces spindle releas-l ing rod 33 outwardly against the linger 63 to' swing thespindle mounting 39 about the eccenf tricpivot 1 3 and move the spindle hub 2| from 75 engagement with belt 3 and into engagement with fixed brake shoe 12 to stop the spindle.

Before leaving the spindle releasing rod 66, it will be further observed thatwhen this rod is moved to release spindle hub 2| from driving engagement with belt 3, it also, through the medium of rod 18, opens contacts 15 in series with magnet 60 to deenergize the same. ing arm 88 and spindle releasing rod 66 remain in their released position, until manually restored by reengagement 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 16 supported by the latch bar 53 in a position directly above the left hand end of roller 83 as viewed from the front. The bolt 55 carries a porcelain guide 11 immediately above the roller 83. The roller 83 which is mounted to rotate with shaft 50 and bevel gear 85, is provided on its circumference with three flat bottomed grooves or channels 18, 19 and 80 separated by square shouldered flanges 8|.

The thread 30 leaves the eye 16, enters the groove 18 adjacent the left side thereof, is carried once around roller 83 in groove 18, passes thence over porcelain guide 11 into the groove 19, once again around the roller 83 in groove 19, thence passing again over porcelain guide 11 to groove 80, thence to porcelain eye 82 and on to the traverse mechanism hereinafter described. The thread is caused to rollV axially of the roller 83 in the grooves thereon, whereby the thread delivered to the traverse mechanism is partially twisted. The flat bottomed grooves 18, 19 and 80, together with the square shouldered flanges 8| 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 I6, a heart-shaped cam 83 is carried thereby, which oscillates an arm 88 loosely journaled upon a rocker shaft 85 extending parallel to shaft I6.

The arm 8 8 carries a cam follower roller 86 which rides on.can 83 to cause oscillation of arm 88. 'Ihe arm 88 also carries a shaft 81 journaled therein on one end of which is fixed a half-heart cam 88 and on the other end there is carried a worm gear 89. 'Ihe worm gear 89 and half-heart cam 88 are driven from shaft I6 by means of sprocket 90 on shaft I6, chain 9|, sprocket 92 mounted on rotating sleeve 93 loosely journaled upon shaft 85. The sleeve 93- carries at its opposite end a worm gear 98 which drives a worm gear 95 upon a shaft 96 extending at right angles to shaft 85 and journaled in a bearing 91 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 85 has affixed thereto a rocker arm 99 which carries at its free end a cam follower roller |00 riding upon the half-heart cam 88. Shaft 85 carries at its outer end a bell-crank lever I0| (see Fig. 2), the horizontal arm of which carries a roller |02 at its free end. 'Ihe roller |02 engages a thrust plate |08 on the lower end of the traverse reciprocating rod |08 mounted in a guide bearing |05, supported on frame I and carrying horizontal ring supporting rods |06 at its upper end. The rods |06 are common to a plurality of units and carry the ring |01. The vertical arm of bell-crank I0| is pivotally connected to a. rod |88 which operates bell-cranks similar to |0| individual to other units and which cooperate to actuate ring supporting rods |06. The ring |01 receives and guides the thread 30 as it iswound to form a cop or quill on the spindle The swing- 20 at a relatively rapid speed and produces through arms 88, 99 and IOI vtraverse 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 ony the quill. Cam 88 moves much slower than cam 83. A ratio of 15 to l isfound satisfactory, though 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 |00 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 |00, the return is effected in much less thanfone-eighth of a revolution of cam 88. Translated to the quill or cop the winding commences at the bottom, the upward traverse is uniform. The downward traverse is also uniform-but 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.

'I'he 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 am not to be limited to the precise form of mechanical movement disclosedA by which this advantageous result is obtained, since other mechanism than that shown may be employed.

No electrical diagram of the circuit for Athe 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 88 when the stop mechanism has been actuated.

In accordance with the present invention, it is possible to throw silk andform crepe silk or rayon cops or quills in one uninterruptedl operation with but one twisting andl 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 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 cops.

By the term lustrous yarn as employed in the appended claims, I mean to embrace such yarns as raw silk, rayon, or artificial silk, spun silk, spun rayon `or yarn made from any of the above fibers, aswell as so-called synthetic pigment yarns. Y

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