Each of the sprockets 50 has a sprocket chain 5| mounted thereon and guided at the lower end on guide sprockets 52. The chain 5| has secured thereto' on each of the side reaches thereof, a horizontally dispose movable rail 54 on which yarn guides 53 are mounted. H

The end frame section l5 has mounted thereon a train of ears 55 which are driven from a; drive shaft 56, the drive shaft 56 being driven by bevel gears 51 from the shaft 28' on which the pulley 21 is mounted. A central longitudinal traverse cani' shaft G'fl is provided between the end frame sec: tions l4 and I5, driven thro'dgh gearing 5| from the gears 55. a I

Thecain shaft Bil has' mounted thereon a trav erse cam 52, preferably of the oylindric'al type. On each sneer the traversecam 62, and en gagement therewith, traverse levers 53 and 54 are provided, the lower endsof the levei's' 63 and 64 being connected respectively by links 65 to the actuating rodsv 4]. 'lhe upper ends of each of the traverse levers and 64 are provided with elongated slots 66 in which a transversely disposed pivot, rod 61, is mounted in engagement with both slots 66 The traverse levers 63 and 64 each have supporting giiides 33, intermediate their ends, movable on horizontal supp'o'rtin'g rods 34. The pivot rod 6| is alsoniounted in guide plates 68, having slots 59 through which bolts 58 extend for adjustably mounting the plates 68 on the frame sections 22. Th e guide plates 63 have guide slots 10 in which the pivot rod His guided.

A control shaft |2 is provided, cente edebove and parallel to the cam Shaft 50; The control shaft 12 is driven by a sprocket 13 and sprocket chain 14 from a driving sprocket 15 carried on the cam shaft 60. The cont'rel shaft 12 is provided, intermediate its ends, with a worm gear is in engagement with a pinion TI on a transverse shaft 18. At the outer ends of the shaft"; a pair of cams 19 of predetermined shape prefer ably to provide uniform lift are mounted; Each of the cams l9 has a pair of opposed follower rollers and 8| in engagement therewith, each of the pairs of rollers 80 and BI being carried on a follower lever 82 of ll-shap'e, pivotally mounted on pivot pins 83.

The link 85 is preferably adjustable in length a1 center line or 4 (see Fig. 4) and for this purpose may include internally threaded heads 85a with a threaded rod 85b extending therebetween and in engagement therewith. A vertically movable fulcrum is thus provided for the traverse levers 63 and 64, for varying the position of the pivot rod 6! with respect to the traverse cam" 82. In addition, by shifting of the guide plates 68 to incline the guide slots 10, a further variation in the effect of the the spindles 30.

movement of the traverse levers 63 and 64 may also be effected; for purposes hereinafter explained. V

The feed; roll rails l9 have mounted thereon feed rolls 8'|,, of any preferred type, which are driven by a shaft 88 having a sprocket 89 thereon, the sprocket 89 being driven by a chain 90 engaging a driving sprocket 9| on a shaft of the gear train 55.

The mode of operation will now be pointed out, reference being had to the packages illustrated in Figs. 6, 7, and 8, and to Figs. 9' and 10.

first that it is desired to employ the niachine'for the production of a yam package P2,

- as ilhfsftrated in Fig. 6, the chain 74 is removed,

the guide plates 68 are positioned with the guide slots 10 alined with the back positions of the traverse leyers 62 and 63, and the shaft 18, and the cams 1 9 actuated thereby, are positioned to locate the pivot rod 61 at the desired elevation in accordance with the desired height of yarn package P2. 1

Upon actuation of the motor 24, the spindle belt 261s actuated for rotating the spindles 30.

The traverse levers, 63 and 64 are oscillated by thetraverse cam 62 which is driven from the shaft 28 through the, gear train. Timed movement of the traverse levers 63 and 64 is effective for moving the ring rails 4| and 42 and the spinning rings 43 carried thereby.

Yarn for the yarn package's is delivered from the yarn packages Pl by the feed rolls 81, is guided by the guides 53 to the spinning rings 43, and is thus directed onto the spools carried by The movement of the traverse levers 63 and 84 is determined by the traverse cam 82, which imparts timed movement of desired amplitude through the links 65, rods 41 and chains 45 which effect oscillation of the ring rails 4| and 42 through the desired path.

It will be noted that the ringrails 4| and 42 counterbalance each other so that no other counterbalancing or counterweights are required.

The number of turns per inch delivered to the spools on the spindles 34 may be readily adjusted The chain 14 is placed in position for driving the sprocket 13 from the sprocket 15. The position of the fulcrum of the traverse levers as determined by the position of the pivot rod 61 will thus be successively varied and while 'a simple harmonic motion may, if desired, be imparted from the cams 19, it is preferred to employ a modifiedmotion to produce uniform movement of the fulcrum in a vertical path; A cyclic vertical movement of the fulcrum with uniform motion will provide the yarn package illustrated in Fig. 7 and with the laps varying in length as indicated in Fig. 9.

If it is desired to produce yarn packages P4, of the character shown in Fig. 8, with a cylindrical section having a conical upper end, the guide plates 68 are shifted to incline the slots 10 towards the end frame section l5 and in alinement with the back positions of the traverse levers 63 and 64. The fulcrum provided by the pivot rod 61 thus has a movement in a vertical and inclined path so that the action of the traverse levers 63 and B4, and the spinning rings 43 controlled thereby, is further modified. It will be noted that as the fulcrum moves upwardly, the back or bottom position of the traverse levers 63 and 64 remains unchanged, because the slots in which the fulcrum moves are in line with the levers 63 and 64. As the fulcrum moves with respect to the traverse cam 62, the forward or top position thereof is changed, giving a longer or a shorter stroke. The longest stroke occurs when the fulcrum is closest to the traverse cam 62 and the shortest stroke occurs when the fulcrum is in its uppermost position. The movement thus effected, produces a yarn package P4 of the character indicated in Fig. 10.

In the simultaneous production, on both sides of the machine, of yarn packages of the character illustrated in Figs. 6 and '7, the springs 45 are not required, although it is not ordinarily necessary to remove the same and provide a fixed or non-resilient connection between the chains 38 and the connector boxes 40. The resilient connections provided by the springs 45 are, however, necessary to produce yarn packages P4 on each side of the machine in which such yarn packages have their upper ends conical. The spinning rings 43 must always come to the same bottom positions on each side, if yarn packages P4 are to be produced. As the spinning rings 43 on one side come to their bottom positions, at the same time the spinning rings 43 on the other side must stop at varying upper positions. The variation of the length of stroke on each side of the machine, to produce yarn packages P4 with conical upper ends, is accommodated by the springs 45 which permit drawing the ring rails 4| or 42 down to the bottom on one side while the spinning rings 43 on the rail 42 or 4| on the other side are at varying upper positions.

It will thus be seen that the machine, in accordance with the present invention, may be readily adapted for a wide variety of packages and with twisting, doubling, or other operations,

as desired.
