This invention relates to .15 builder motion for yarn packages and is illustrated as applied to a spinning machine. L

In the usual builder motion provided on a spinning frame, the traverse for the yarn which is wound upon the package is of uniform length which shifts to progressively higher positions on the vertically wound package until the package is completed. In the winding of yarn in this manner the convolutions of yarn will lay one on top ofvanother in such a manner that the package will sluff or the windings of yarn slide one upon thevother and become loose.

One of the objects of this invention is to provide a yarn package in which the yarn will be so wound that one convolution of yarn will not Figure 4 is a view in the nature of a top plan view showing parts in section to better bring out their relationshipand expose the relatively movable operating parts;

t This invention may be viewed as an attachment to the usual rockable arm of a spinning be directly on top of another so as to permit of a slufling of the yarn and an upsetting of the package. I

Another object of the invention is to provide a traverse motionso that there will be a non-frequent repeat of the manner .in which the yarn is laid upon the package.

A more. specific object of the. invention is to' vary the traverse of the yarn makingit non-uniform to prevent the laying of the convolutions of one layer of yarn directly over those of the layer below it.

Another object of this invention is to provide a constant and gradual change of traverse asdistinguished from a step by step change.

Another object of theinvention is to provide an arrangement whereby the range of traverse may be varied in length by a simple adjustment oil the parts. I

Another object of the invention is to provide a variable traverse motion in which the parts may be well lubricated.

With these and other objects in view, the invention consists ofcertain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is an elevation showing a builder motion arm equipped with my invention, the frame of a spinning machine being fragmentally shown frame through which the builder motion operates. The builder arm is rocked in the usual manner by a cam provided for this purpose. In-

stead of connecting the arm directly to the ring rail by means of a sprocket chain or the like I interpose between the arm and the chain an arrangement which in effect varies the length of traverse of the ring rail. The variation continually changes over a range of traverse which varies in length thereby providing a maximum and minimum length for operation. Thismaximum and minimum length, however, may be additionally changed by an adjustmentwhich is "provided while the traverse itself may also be adjusted by lengthening the main arm or in effect the point of attachment of the chain along the main arm.

With reference to the drawings I0 designates the supporting framework structure of the spinning frame from which there projects a bracket l I (see Figs. 1 and 5) having bearings l2 and I3 to rotatably support a shaft l4 upon which the hub l6 of the builder motion arm I6 is pivotally mounted (see Fig. 4). This arm has an extension designated generally I! thus providing this arm in two pieces. Upon the upper surface of the arm l6 bosses l6 and iii are raised (see Figs. 4 and '7) to rotatably support a cam follower 20 by meansof trunnions 2| extending from either side thereof. The main operating cam 22 (see Figs. 1, and2) engages this cam follower and is secured to a'shaft 23 which is mounted in the bearing '24 extending from the frame I0. This shaft 23 is driven by a gear-'25 engaging the spiral pinion gear 26 on the drive shaft 21 which extends downwardly from the train of gears at the head end of the spirming frame.

The portion ll of the builder motion arm comprises a member (see Figs. 4 and 6) which has recesses II to fit the boss 32 which extends inwardly from the arm l6 and thus provides a .trackalong which this member 30 may slide.

Suitable slots 33 and 84 are provided in the member 38 through which bolts 85 and 35 extend to bind the member 38 in position. A boss 31 is provided on the arm l8 through which a threaded set screw 38 may extend to be adjusted by means of a head 88 and held in position by the binding nut: 48. The end 4| of this screw provides an adjustable abutment for the end 38 of the arm I 1 and may be utilized to force the arm I: outwardly to extend the length of the arm The outer end of the arm member ll consists of a bearing annulus 45 into which there is received a guide member 46 which may be rocked to any relatively angular position of rotation in the bearing annulus 45 and there held in position by the bolts 41 threaded into the guide member 48 and provided with washers 48 beneath their heads 48 to engage the annulus for binding the guide member in position. On the inner surface of the member 48 there are provided parallel suideways 58 for directing the movement of a slide 5| which slide provides a suitable bearing as at 52 (see Fig. 2) for a cam follower 53 which is carried by the slide. The cam follower is supported at the other end in a bearing 54 provided in a yoke 55 which is attached through a chain 56 to mechanism for reciprocating the ring rail. The chain 58 is connected to a drum 51 keyed to shaft 58 to oscillate this shaft 58 while complementary chains 58 extend from other drums 80 at as many points as is desired from the shaft to links 8| which conveys reciprocatory movement to the ring rail of the spinning machines or to any other part which may act as a traverse for the yarn if some other form of traverse than a ring ing to keep the cam follower in engagement with the cam at all times. This causes the usual movement of the builder arm. This usual movement'of the builder is varied by the cam 88 which is carried by th builder motion arm and constantly-rotated at a lesser speed from the main'cam through gear 'l l, chain I3, gear 12, shaft l4, gears," and 80, shaft 14,

gears

83, 84, and 85, and shaft 81. The movement of the cam is transmitted through follower 53 to slide 5| and yoke 55 to which the chain 58, rock shaft 58 and chain 58 supply the connection from I the builder arm .to the ring rail. By this arrangeand traveller is provided. A skeleton framework 65 (see Figs. 2 and 4') is supported from the guide member and extends upwardly to provide a bearing 68 for a shaft upon which a cam 58 is fixed for engagement with the cam follower 53.

This framework also supports a boss 88in which the shaft 18 is rotatably mounted for the support of a worm gear as will presently appear. This shaft 10 has its axis coaxial with the center of the annulus or bearing 55.

The cam 68 is driven from the main cam 22 by the gear H mounted on theshaft 23 which drives by sprocket chain 13 the gear 12 mounted on the shaft I4 upon which the builder motion arm 18 is pivotally mounted.

A shaft 14 has abearing 15 (see Figure 1) secured to the arm l6 and also a bearing 16 supported as at 1'! from the portion ll of this arm and movable therewith. This bearing may be independently adjusted with this portion I! by reason of the slots TI and bolt 18 by which this hearing is secured to the part II. The shaft I4 is driven by the spiral gears ill on the shaft I4 and 80 on the shaft I4. This shaft 14 is provided with splines which slidably engage complementary grooves in gear 88 and has abutment collars 8| and 82 engaging the bearing 16 while it drives the worm gear 83 which in turn drives the worm gear 84 on th shaft HI and spiral gear 85 keyed to shaft 51 which transmits motion through this shaf '01 to the cam 68. a

In operation the main drive shaft 21 will operate the cam 22 which will engage cam follower 28 to force the builder arm l5 and its complementary part II which-is connected to the ring rail downwardly, the weight of the ring rail servment, the traverse which may heretofore have been five and one-half inches with the cam 22 "alone will be varied so that it will be from five and three-eighths to live and flve-elghths inches with much less opportunit for a repeat to occur in the lay of the yarn on the package. For relatively small diameter yarn such as glass yarn, a ratio'of20 to 1 between cams 2 2 and 88 has been found satisfactory. A ratio of 40 to 1 has been found sat factory for. relatively coarser worsted yarn. l-fqqever, this may be varied if desired.

If it a; desired to additionally lengthen or shorten e traverse'this may be done by loosen- ,ing bolts -36 and sliding the part 11 with reference to the part It and adjusting the screw 38 to the proper position. After this adjustment has been made it is clamped in position by the nuts 35 and 35. Since the bearing 18 is fixed to the arm I! adjustment of arm l1 along the arm [8 will not disturb the relationship between the gears carried by the shaft 14 and arm ll.

The length of the traverse may also be conveniently regulated by inclining the guide carrying member 48 with reference to the builder motion arm. The guideways 50 may be rotated in the annulus 45 fromthe position, such as illustrated in Fig. 3, so that their guiding edges will This bearing 86 extends through the yoke 55 which will be readily apparent from Figure 2.

be parallel to a line shown dotted in Fig. 3. This adjustment carries with it supporting bracket frame 65 which pivots around the'shaft It as a center and also carries with it the cam and gear 85. By movement to the inclined position illustrated in Fig. 3 by dotted line 98 thelength of the traverse will be increased while by inclining the guides in the opposite direction to the dotted line 8| the length of the traverse will be decreased. If desirable, indicating means showing a plus and minus graduated amountsmay'be provided on the annulus. 45 and guide carrying member 46 that the desired adjustment may be had. The diagrammatic showing in Fig. 3 wiil make plain the relative motions which have been above described.

In Fig. 8 I have illustrated a package having ends 86 tapered which is the form of package desired to be wound on the spinning frame equipped with the builder motion above described. The layers of the yarn will be sufliciently irregular so that one convolution will not lie above another and there will be a long interval probably carried by said arm and a. slide movable in said guideway; an auxiliary cam follower carried by said slide, means for connecting said cam follower to a yarn guide, a second cam carried by said arm for engaging said auxiliary follower, and means operated from the driving means for the first cam for rotating said second cam.
