BOBBIN-WINDING- MECHANISM AND SPEED CONTROL THEREFOR.

Original application led October 9, 1919, Serial No.v 329,471. Divided and this application led May 24, 1922. Serial No. 563,405.

To all whom it may concern.'

Be it known that I, CHARLES A. HUT- 'rINGER, va citizen of the United States, resident of Lakewood, county of Cuyahoga,

and State of Ohio, have invented new and useful Improvements in Bobbin-lVinding Mechanism and Speed Controls "Ihercfor,

of which the following is a specification, thel lprinciple of the invention being herein eX- plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The subject matter of this application has been divided out of my pending application,

Serial No. 329,471, filed October 9, 1919.

My invention relates to bobbin winding mechanism and speed control therefor and particularly to-apparatus of this character utilized for winding upon bobbins artificial silk such as viscosev threads. Particularly, my invention relates to means in apparatus of this character in which the thread is subjected to a minimum amount of friction when being wound.

The annexed drawings and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of the various mechanical forms in which the prin- 30 ciple of the invention may be employed.

In said annexed drawings:

Figure 1 represents a plan view of a fragmentary portion of my machine;

Figure 2 represents, upon an enlarged scale, a vertical longitudinal section, taken in the plane indicated by the lines II-II, Figures 1 and 4;

Figure 3 represents a transverse vertical section taken in the plane indicated by the line III-IIL Figure 2;

Figure 4 represents a fragmentary side elevation; and

Figure '5 represents a fragmentary end elevation.

Referring to the annexed drawings, a plurality of pairs of shafts 1 and 2 are mounted in a suitable frame, each pair of shafts, in the manner hereinafter fully described, forming part of the means for rotating by 'frictional rolling contact a series of longitudinally disposed bobbins 25. 'Io each of` the shafts 1 and 2 and adjacently one end thereof is secured a pinion 3, an idler 4 being positioned between the two pinions of the pair of shafts, so that the latter both rotate in the same direction. A suitably mounted pinion 5 intermeshes with one of the pinions 3, Figure 5, and also intermeshes with a gear 6 secured to a shaft 7, the gear 6 directly driving one of the pinions, designated as 3', Figures 1 and 5, so that the' directions of rotation of the respective bob- 1 bins 25 are as shown in said Figure 5. Also secured to said shaft 7 is a friction disc 8 adapted to be rotated by meanso-f frictional contact with a disc 16 secu-red to the top of a vertically disposed shaft 17. To the bottom of said shaft 17 is secured a bevel gear 18 intermeshing with a bevel gear 19 secured to the end of a horizontally disposed shaft 20. Adjacently the other end of said shaft 20 are mounted tight and loose pulleys 21 vand 22, respectively. Power from any suitable source is secured, and applied to the system through the medium of said pulleys 21 and 22.

Mounted upon each of the shafts 1 and 2 are a series of pairs of raised cylindrical surfaces or rollers 23 and 24 having exterior flanges 23 and 24. The bobbins 25 rest upon said cylindrical surfaces 23 and 24, each bobbin resting upon two pairs of said surfaces, as plainly shown in Figure 1. The bobbins when filled are thus easily removed and replaced. The body of thread 26, shown in Figures 1 and 4, representsy the condition when a bobbin 25 is wound about half full of the viscose thread 27 received by a porcelain guide 28 from a second guide 29 positioned in and extending from a trough 60 containing the usual precipitating bath. The viscose solution is expressed from the nozzle 30 into the bath contained in the trough where it is precipitated and solidified into the thread 27.

In order that the thread may be wound longitudinally of the bobbin 25, I provide means for reciprocating the delivered end of the thread longitudinally of said bobbin. rlhis is accomplished through the medium of a reciprocating bar 31 upon which the porcelain guides 28 are mounted. This bar fra ' 36 formed with brackets 37 shaftl 35. As hereinafter fully described, f

the pin 32 is secured' to a handle 56 pivoted upon the bar 3l. Also secured to said hub portion 35 is a downwardly extending arm externally threaded memberl 38. A' casting' 39 may be reciprocated vertically upon the screw 38 by the means hereinafter fully described. -Secured to this casting 39 is a'link 40 whose other end is pivotally connected to one end of a transversely extending arm 40', Figure 1 which is pivoted. at its other end to the frame of the machine, part of the means forming said pivotal connection between the link 40 and the arm 40' consisting of a rounded end portion 402 upon the arm 40 by means of which the arm 40 may be moved longitudinally of the other end of the link 40, for a purpose hereinafter fully described. Mounted intermediate of the ends of the arm 40 is a flanged roller 42 adapted to ride upon a face cam 43 secured to the power shaft 20, said roller being held to position -by a spring 44, Figure 4. 1t is evident that the apparatus so far described will provide means for rotatin'gthe bobbins 25 by fractional contact and for winding the thread 27 longitudinally of said bobbins. The arrangement is such, as plainly shown in Figures 1 and 4, that a very small number of rotations of the shafts 1 and 2 takes places during a single reciprocation of the bar 31, so that the thread 27 is wound .upon the bobbin 25 with comparatively large open spacesl between adjacent turns ofthe thread.

As is plainl apparent in Figures -1 and 4, the thread 2 is so wound upc-n the'bobbin 25 as to provide at each end of the body 26 of thread a beveled edge 26. This is to insure the integrity of the wound thread against unraveling and is attained by the fol lowing means, altho claims to the same do not form any part of this application but are ineluded in my pending application Serial No. 329,471, upon traverse mechanism for winding machines, of which the subject matter vof this application is a division. This application Serial No. 329,471 has resulted in U.

S. Patent No. 1,425,655.

Secured to the bottom of the screw mem-V threaded engagement by a spring 48. The

result is that the casting on crosshead 39 is fed downwardly slightly each time the supporting an,

america ratchet 45 strikes the stop 46 to shorten up the stroke of the bar 31 upon which the porcelain guides- 28 are mounted. Whenever it is desired to return-the crosshead 39 to the top of the screwmember 38 to `start a new stroke, after one bobbin 25 has been fully .wound, the spring 48 is losened manually to release the blocks 47 from the screw member 38 and the crosshead 39 shoved upto the upon the thread, 1 provide means for constantly slowing'up the speed of the shafts 1 and 2. Generally, this is accomplished by a change in the position of the frictio-n disc 8 upon the, friction disc 16 at each turn of the shaft 20." The detail of this arrangement consists of the following means.

Loosely mounted upon a sleeve 10 rotatably mounted upon the shaft 7 is a bell-crank having arms 11 and 11. Secured to the arm 11 by a suitable pin is a pawl 13. This pawl co-operates with the ratchet 14 fixed by any suitable means to the sleeve 10 and fixing longitudinally ofthe shaft 7 a shoulder 9 ofthe friction disc 8 which is secured by a run# ning it in a suitable groove formed in the sleeve 10. This sleeve member 10 is formed een with a peripheral screw threaded porti'on y turn is secured at its lower end to an ecccntric stra 54 secured to the4 driving shaft 20. 1t is evi ent that each rotation of the driving shaft 20 will result in -a feeding of the sleeve 10 through the nut 50 and consequently in a movement of the friction disc 8 to- \ward thecenter of the friction disc 16, thus slowing up the speed of rotation of the shaft 7 and consequently of the roller shafts 1 and 2. ln order that the highest rate of speed of the shafts 1 and 2 may be secured at the time of the winding upon a new bobbin, the sleeve 10 is relieved from the 'blocks 51 by means of releasing manually the spring 52, and the friction disc 8 and shaft 7 pushed 'to the right, Figure 2, by meansv of a handle 55, the locking pin 55 sliding in the kannular recess 7 2 formed around an intermediate re` duced portion 73 of the shaft 7.

1t will be notedin Figure 1 that adjacent longitudinal pairs of the rollers 23 and 24 are not utilizedat the same time but that the bobbins 25 are mounted on `alternate f and acting t means automatically to change the relative pairs. The result is that when the bobbin mounted upon one pair of said rollers is full wound, the bar 31 is shifted longitudinally the desired amount to bring the guides 28 adj acently the alternate bobbins. This is accomplished by the following means, which, however, are particularly claimed in said pending application, Serial No. 329,741.

A handle 56, Figure 4:, is pivoted to the bar 31 at one end upon a pin 57 and detachably locked at the other end by a pin 562. The latter is released from the bar 31 and the handle is turned upwardly so as to release the pin 32 from the yoke 33 and the said bar 31 then manually shoved longitudinally until the pin 57 lies in the former position ofthe in 562 when, by lowering the handle and ocking the pin 562 in the position 56', the pin 32 again registers with the yoke 33 and the guides 28 are disposed adjacentl the alternate bobbins 25.

It will be evident from the accompanying drawings that only one unit of my improved bobbin winding mechanism and speed control therefore has been described and that the entire machine consists of a multiplicity of said units, two or more pairs of shafts 1 and 2 being operated simultaneously by means of multiple arms 34 and '34', multiple pinions 3 and other necessary multiple parts.
