UNITED STATES JAMES D. JOYCE, OF PHILADELPHIA, PENNSYLVANIA.

WINDING MACHINE.

Application filed January 25, 1924. Serial No. 688,592.

To all fr/0m t may concern:

Be it known that I, JAMES D. JOYCE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Winding Machines, of which the following is a specification.

This invention relates ingeneral to winding machines, and more particularly to a winding machine having means for simultaneously winding a plurality of bobbins, each of which is separately and automatically controlled.

It is an object of my invention to provide a novel and improved bunch building means for winding machines of this type.

It is a further object of my invention to provide a novel and improved control mechanism for winding machines such that if the thread or yarn being wound breaks, the spindle of that bobbin will be automatically thrown out of action. Means is also pro vided for automatically throwing the spindle out of operation when the same is complete ly wound.

It is an object of my invention to provide a novel type'of brake means, automatically operating to stop the rotation of the spindle when the sameis thrown out of action.

It is a further object of my invention to provide a novel type of travelling thread guide carrier, the follower of which can rotate in but one direction and thus provides against any back lash of the carrier.

Other objects and advantages of my invention will appear in the accompanying specification and claims and will be disclosed in the accompanying drawings in which- Figure 1 is a plan view of a portion of my device showing one of my opposed winding devices and a portion of my power transmission system;

Figure 2 is a vertical section through the transmission housing;

Figure 17 is a view similar .to Figure 10 showing a modification of my device;

Figure 18 is a detail view of the arm acted on by the thread guide to lthrow out theclutch when the bobbin is full.

Referring with greater particularity to the drawings, and, for the first portion of this specification, having reference especially to Figures 1-13, inclusive, it will be seen that my device is comprised as follows:

My machine is adapted to drive a plurality of spindles arranged in two longitudinally` extending banks or rows. Each spindle in each bank is each mounted opposed to a spindle of the other bank so that thetwo spindles are adapted to ybe operated by a. common operating means. Since the construction cf each of the spindle operating 1 means is substantially identical, the description is limited largely to the description of but one of such means.

Referring lirst to Figures 1 and 2, it will be seen that the power for the operation of my winding machine derived from any suitable source is applied through a drive shaft 1. One end of the drive shaft 1 extends into a transmission housing l and has suitable bearings 1b. Mountedvon the end of shaft 1 is a pinion gear 2, adapted to mesh with and drive albevrel fgearf fsecured; to alg-stub shaft 4 mounted in suitable bearings in the housing. FiXedly secured to shaft 4 isa cam block 5 having a cam track y5a in which-a pair of oppositely spaced rollers 6 secured to rock arms 7 are adapted to travel. IThe rotation of shaft 4 will thus result in the oscillation of the rock: arms 71and hence of the rock shafts 8 on which the said arms are mounted. The rockingl of shafts-8, asl-will be later described, provides forfthef traversingimoveinent' of thethread kguide and Vmany of the other of the moving parts ofmy device. ,l

Fixedlyf mounted on shaft 1 aiea'plurality of friction wheels 9, each ada-ptedat its periphery" to drive a pair of friction/disks 10, mounted fon shafts' 11 'to rotate therewith but' sldable` thereon,`r which shafts carry the spindlesv on whichv the b'obbins 12 are tolbe wound. The thread y or yarn 13 passes through eitherl of two' thread-guides 14aor 14h, the guide 14a being used whenthe thread is"y fedv from* belowv Ethey spindle and thefguide 14b being used when the thread isfed'from above. (See vFigures" 14 and 10). The thread then passes through the travelling thread guide 15 and'ov'erf a-bentf'p'in 16p o`n the bunch building device'.

Reference being had especially'toFigures 1 and', it willbe seen that a clutch 17, which can be throwni'ntoor out of operation by a handle 18, is mounted on the shaft 8; This 'clutchis also capableof automatic control, 4a'swill be disclosed'inthe following specification.

Mounted on^a`-collar a on'ishaftl Sris a substantially 'vertically` ertending rodv 20, y'to which there'is pivoted at 21 abat" 22, which bar is; reciprocated longitudinally of.` the spindle by the oscillation of Jthe shaftxS. The bar 22-has 'secured thereto the bars 23 a1id'24` which carry one end of ythe rod 25, along which thel travelling .thread guide moves,gandy the Shaper rod 26. The collar 2O*l is adaptedr tobe engagedby thel clutch n thfoghf alemana; or pin 1n'- aas-pred ythe frame of `the machine.

to bemo'ved into or outV of a slot 20h inthe col'lafr20a.y as vtheclutch ism'oved longitudi- 7, 8"and` 10, it .will be seen that the'bent pin mounted on angai'nrBO, pivoted :at :31 toy a* member 32, which' in turn isv pivoticd to 'y he `end of the `arih' 30- lies against the under' face of' the few turns of thread which are manually wound on the bobbin as'fitI isplaced-in` position. VAs the spindle Vis put into operation the thread'` is restrainedv from' the`-travers ing movement of the guide 1-5 by the bent in 16'. `As'th'e bunch ,isbeing built, the end 34- of the arm 30 will be gradually push'edf'downwardly about the pivot ulltil the inner end 35 of the arm 30 is in registration-'With a; slot 36,-in plate=567 secured to th'e 1fra'Inel The spring 38 w will then cause` the arm 3() to rotate about pivot 31,

`causing-.the bent end ofthe pin 16 to move out of engagement with the thread, and the ,wndinglproceeda the thread now being reciprocated along the bobbin by the guide 15.

"Thethreadfguidei14a is secured by means of a collar 40 to a rod 41. On the inner end of rod 41 there isffixedlyfmounteda curveda'rm 42 ;ca'rryingpins 243 between-which passes Qthe'farmi-44' which lcarries the thread guide* carrier 141". Iffthe thread guide 14a isb'eing used andthe thread breaks,'the arm carrying 14l'will drop,` rotating th'eshaft 41, arm 42, and byf'm'eans of'pins48 draws down on arm 44 rotating thfe col1ar44f on the stud 45" to which collar arm 44E is secured. 'The collar 44a also carries a finger 46'w1hich rotates-*within lf the threadiis carried by guide 145 thel z1n144 will fall whenthev thread breaks thus rotating the collar 44l andfinger 46.

Mounted on Irod 24 is a collar 47 (se'e Fig. 3") which reciprocates therewith. A stub shaft 48 mountedin'the frameof the ma chine Carries a finger49 and a collar l50. Mounted onV the handle 18 is a'finger 51 bearing against the periphery` of collar-50 and holding they clutch in ei'igagem'ent against thet'ension of a spring 52, V'lfhefc'ol-4 lar' 47, atjthe end'of the outwardstroke of the ro`d'247 does not' quite reac'hthe linger 49.

Ifr the :thread: breaks, however, theythreads guides drop raisingy the finger 46-intofthe path of the collar 47. Then,- as vthe rod 24 nears the outward en'd of its stroke, the collar v47 will strike theflinger 46 whichinturn strikes thefinger49 movingthe shaft 48 longitudinally and moving the collar 50 out ofcngager'nent with the finger 51.

The spring 52 will then .cause Vtheha'ndle 18th turn through apartial revolution, and through the medium of the arm 55 and the pin 56, will throw the clutch out of engagement, 'thevv pin ..56 .ridingin a-` groove in the clutch. y p

Pivoted on a pin 60, which is secured to the frame, is a lever 61, to the outer endof which there is secured the spring' 52.l 'At the opposite end of the lever 61i's a brake 62, so mounted that, when the spindlev is thrown out of action, the brake4 62 will strike the disk 10 pushing it away from the drive wheel 9 and stopping the same.

'The lever 61 carries a' hooked finger 64 which isin engagement-with apin 65 on a cam member 66V rotatably mounted on shaft 11.' The cam member 66-is adaptedv to c'o`act with a cani 71 fixed on the shaft 11. When the clutch is thrown in,the lever 61 is raised by a pin 68 secured on an arm69 mounted onthe handle rod 18. This releasesthe pull on 65, and by means ofthe pull of a weight- 70, and the gradual pull of light springs 77 the cam member 66 will be rotated bringing the highest portion of its cam surface into engagement with the highest portion of the cam surface of the member 71, and thus moving the disk 10 into engagement with the wheel 9 which drives the spindle, the clutch 66 and disk 10 being secured together. It is to be noted that the clutch is moved longitudinally of the shaft 8 in such a manner that, when the clutch is thrown out the pin 17a is withdrawn from its groove in the collar 2Oa and the oscillatory motion of rod 20 is stopped.

l/Vhen the spindle is fully wound the arm of the thread guide carrier assembly will engage the nger 76 mounted on the shaft 41, thus partially rotating the shaft 41 and, through the medium of

arms

42 and 44 will raise the 'finger 46 into the path of the collar 47 and throwing the spindle out of operation.

In Figure 16 I have shown a modification of my invention in which I have replaced the cam, weight and spring clutch mechanism, 64, 65, 66, 70, 77, by a compression spring 81 mounted on shaft 11 between the frame and the disk 10. This spring is of less strength than the spring 52 so that when handle 18 is rotated to throw the spindle out of action the spring 52 acting on one endV of the lever 61 will force the brake 62 against the disk 10 and force the same, against the action of spring 81, out of engagement with the wheel 9. Vhen the spindle is again to be placed in operation the rotation of the handle 18 withdraws the brake from the disk and the spring 81 forces the disk into engagement with the wheel.

In Figure 17 I have disclosed a modification of the mechanism shown in detail in Figure 11, especially

parts

14h, 42, 43, 44, 45 and 46. In this showing I have done away with the curved arm 42, pins 43, and stud 45 and have shown the finger 46 as twisted and secured directly to the shaft 41, to which the arm of carrier 14b is directly secured by means of a suitable collar.

Referring now especially to Figure 6 it will be seen that the

rods

23 and 24 are secured to each other by plate 28, the arm 23 being extended at 27 to form a support for the Shaper 26 xedly secured thereto.

The plate 28 has a longitudinally extending slot 28 in which a pin supporting one end of the rod 25 is adapted to travel. The other end o-f rod 25 is pivoted at 82 to a plate 83.

By reference to Figure 9 it will be seen that I have provided a spring 84 one end of which is attached to a finger extending from the rod 23 and the other of which is secured to a finger extending from the rod 25. This spring tends to bring rod 25 into alignment with the rod 24. A suitable friction collar is provided with spring 86 abutting a collar 86a and is adapted to bear against the edge of plate 28.

A linger 87 has an undercut portion 88 adapted to bear on the edge of the shaper,

the finger being mounted on a portion of bers are secured to collars 91 and 92 which are mounted on a sleeve 93 on rod 25. The sleeve 93 has secured thereto, by means of a collar 94, a follower wheel 95 the periphery of which is adapted to touch the yarn on the bobbin as it is wound and thus rotate the wheel. Pivoted to the wheel 95 at 96 is a bent arm or yoke 97 which is shaped as shown in Figure 11 to provide a housing for a worm gear 98 and bearings for the shaft 99 on which the said worm is mounted. The gear 98 extends through a recess 98 in the sleeve 93 and engages the threaded rod 25 with which it is, held in engagement by a spring 100. The rotation of the wheel thus results in the whole thread guide assembly' being moved along the rod 24.

A spiral spring 102 is wrapped tightly around the extended arm of the shaft 99 in the manner shown in Figure 11. The inner end of the spring is held in position by yoke 97. While the worm 98 can be rotated in a counterclockwise rotation as viewed in Figure 12) it will be seen that any attempt to rotate the Worm in the opposite direction would cause the spring 102 to bind the shaft 98 and prevent rotation. To move the thread guide backwards then, it is necessary to raise the yoke 98 about its pivots against the actionfof spring 100. The carrier can thenbe movedY back to any desired position, the sleeve 93 now sliding freely on the rod 24.

In the device shown in Figure 14 I have dispensed with the

double rod

23, 24, 25, 27 and' have substituted a single rod 25. The shaper is naturally dispensed with and the bobbin wound is, when completed, as shown iu Figure 15.

The operation of my device having been fully disclosed, it will be seen that I have provided a winding machine for simultaneaously winding a plurality of bobbins, each bobbin being independently and automatically controlled in its winding, having novel means fo-r automatically throwing a bobbin into or out of operation when the thread feeding it breaks or when the bobbin is fully wound; which has a novel and improved type of bunch builder; and which is simple in construction and operation.
