Application June 10, 1933, Serial No. 675,162 In Germany June 24, 1932 11 Claims.

This invention relates to the winding of threads or yarn, but primarily'has for its object the production of a yarn body having an improved build Another object of the present invention is to devise a mechanism whereby the method in which the filaments are wound on the take-up means facilitates the after-treatment of the yarn.

Further, another object of the present invention is to provide a means whereby the stroke of the thread guide is varied during every traverse motion of the thread guide and at the same time is decreased as the thickness of the wind increases.

These and other objects of the present invention will in part be pointed out and in part become obvious from a study of the following description and' by references to the attached drawings, in which:

Figure 1 is a side elevation of one form of the device with such parts of a spinning machine being shown to illustrate the application of the invention;

Figure 2 is a detail plan of a portion of the device;

Figure 3 is a side elevation of 'a'modification of the invention when the so-called wandering or pilgrim stroke is desired;

Figure 4 is a detail section of a modified form of mechanism for decreasing the length of the v thread guide stroke;

Figure 5 is a front elevation of the parts illustrated in Figure 4;

Figure 6 is a vertical cross section on the line 66 of Figure 5;

Figure 7 is a graphical representation of the manner in which the thread is laid on the spool when the form of gearing illustrated in Figures 1 and 2 of the drawings is used; and

I Figure 8 is a graphical representation of the manner in which thethr'ead is laid on the spool when the gearing=illustrated in Figure 3 is used.

art is a tendency toward a lack of uniformity in physical characteristics of the filaments, which tendency appears to be caused by the tension created during drying by uneven shrinkage. It must be borne in mind that the freshly extruded filaments are quite plastic in character and are therefore easily affected by any strain which may be placed on them while in this state.

It is also known that closely wound yarn bodies on the spool are difficult of penetration by the after-treating solution to which they are subjected making it necessary that during the takeup of the filaments they are so wound as to allow as many interstices as possible to be formed in said yarn body in a manner pointed out in the present invention. By so doing the liquid used in washing or dyeing processes will penetrate the yarn body more easily than would otherwise be the case, thereby materially reducing the time necessary to complete such processes.

It has also been found that if the yarn body is bevelled through a constant alternative displacement of the stroke of the thread guide, overlapping at the ends and ridges throughout the rest of the yarn body are the result, which ridges cause variations in the denier of the filaments, dyeing differences, and open thread windings.

It is therefore the purpose of applicants invention to overcome all of these disadvantages by devising a mechanism which will lay the filament windings on the spool with a combined oscillating or additional to and fro movement of the thread guide during each backward and forward transverse movement along the spinning spool and a gradual decrease of the length of the over-all stroke of'the thread guide after each layer of yarn wound on said spool.

In the drawings in which like numerals of reference indicate like parts, I indicates the back board of a spinning machine, only so much of v which is shown as is necessary to illustrate the application of the invention. The filaments 2 are extruded from the spinnerette (not shown) and carried through a thread guide 3 then over the take-up spool 4.

The spool 4 is mounted on a shaft 5 and rotated thereby, the shaft 5 being driven by a power shaft 6 through the medium of spiral gears 'l'l. The shaft 5 has bearing in the back board I as shown at 8 and is prevented from endwise movement by collars 9.

The thread guide 3 is rigidly attached to a rocker arm H) which is mounted on a rocker shaft H and oscillated thereby.

The rocker shaft II is oscillated through the medium of a cam and lever arrangement. A

. swingable thereon.

The lever l4 as it is reciprocated up and down by the cam 12 operates a. second lever l6 which is fixedly mounted on the shaft i l by a set screw I1. The lever l6 having at its outer end an eccentric shaft I8 and roller l9 adapted to rotate on the eccentric of the shaft l8. This roller l9 contacts with a .raised slideway 28 integrally formed on the top of the lever l4 for a reason that will later become apparent. A spring 2| is attached to the under side of the lever I 6, the purpose beingto always insure positive contact between the two levers and IS. The other end of the spring 2| is attached at 22 to the bearing 8.

Mounted on the shaft l3 and rotating therewith is'a gear 23 which meshes with an intermediate double gear 24 carried by the stub shaft 30 which is secured in the bearing bracket 3|. The other gear portion 25 of the double gear 24 meshes with a second double gear 26 and 21 which is freely rotatable on the rocker shaft II. The gear portion 25 meshes with an intermediate gear 28 mounted on the lever IS. The intermediate gear 28 driving a pinion 29 secured on the eccentric shaft [8 and thereby rotating said shaft l8.

It will be readily apparent from the foregoing description that as the shaft l3 rotates the cam I 2, the rocker shaft I I will be oscillated by reason of the levers l4 and I6 being reciprocated up and down, thereby oscillating the rocker arm I and imparting to the thread guide 3 a reciprocating It will also be readily apparent that a number of additional oscillations are imparted to the thread guide 3 during one traverse across the spool 4 due to the speed of rotation of the eccentric shaft l8 being greater than the rotation of the cam l2. The result being a. combination undulating traverse wind as illustrated in Figure '7 of. the drawings, by reference to which,-it will be noted that the filaments are undulatingly cross wound on the spool, the consequence being that additional in-,

terstices are placed in the yarn body which will improve the washing and treating thereof.

In order that the yarn body as it builds up will not overlap at the ends and result in variations of denier, the over-all length of the stroke of the thread guide is decreased after each layer of yarn is wound on the spool. This is .done by angling the contacting surface of the cam l2 and shifting the shaft l3 as the wind increases in diameter.

The shaft 13 is shifted by means of a forked lever 41 which is connected to the shaft l3 by a grooved'collar 48 rotating therewith'and pins 58 which project in the grooved collar 48 andwhich are mounted in the forked lever.

' A cam roller 5| is mounted on the other end of I the lever 41 and contacts a cam 52. The cam I2 is rotated through the medium of bevel gears 53,'a reduction gear train 54 which is driven from the main drive shaft l3 by a drive gear 55 mounted thereon. I

As the drive shaft l3 rotates to drive therecip rocatingcam l I, the cam 52 is slowly rotated and rocks the lever 41 which moves the shaft l3 in an endwise direction as shown by the arrow.

By reference to Figure 2 of the drawings, it

' will be clearly apparent how this is brought about.

roller l5 as shown in Figure 2 is the position of The letter A indicating'the distance, from the I center of rotation to the operating surface of the cam is seen to be longer than distance 0;, The;

distance B allows the lever 14 to return closer to the center of rotation than the distance'D will allow. It is therefore easily seen how by moving.

This is. graphically shown in Figure 7 of the drawings where the lines EF represent the a greatest length of stroke and the lines EG indicate the gradual decrease in length of the stroke.

This mechanism therefore will give a yarn body with bevelled edges (which do not overlap) anda yarn body that will be more easily penetrated by treating liquids due to the combined decreasing oscillatory stroke of the traverse motion.

In Figure 3 is shown a modified arrangement in which the gear ratio has beenchanged to make the speed of rotation of the eccentric shaft l8 slower than the rotation of the cam l2, the result being a different type of stroke which is not oscillatory but which'gives a gradual, displacement of stroke, first in one direction and then in the other. v I

In this form the intermediate gear 28 hasbeen eliminated and a larger gear 32 substituted for,

the pinion 29. The gear 32 is suiliciently large in diameter to mesh with the gear 21, the rest of the gear train 23, 24, 25, 26 and 21 retaining the were shown in' Figures 1 and 2.

'By substituting thislarger gear 32 for the in .termediate gear 28 and the pinion 29, it will be observed that the speed of rotation of. the eccensame proportions and positions in which they tric shaft 18 will be" slower than the speed of Y rotation of the cam 12 resulting in the type of wind such as illustrated in Figure 8 of the drawings by reference to which it will be, observed that the stroke wanders in first one direction and then in the other direction. The decreased length of the wind is indicated by the lines EF-and 4 samemam, T,

E--G. which is brought about in the ner as described in the first form.

In Figures 4, 5 and6 is illustrated a.modifled form of that p rtion of the invention. wh

From the foregoing description it will easily be seen how by sliding the shaft l3 to the left in Figure 4 of the drawings the center of the cam I20. will be changed to decrease the length of the stroke.
