BUILDER-MOTION FOE SPINNING-FRAMES.

Specification of Letters Patent.

Application filed December 15, 1916.

To all whom it may concern:

Be it known that I, ALoNzo E. Ri-ioAnEs, a citizen of the United States residing at Hopedale, county of lVorcester, State of Massachusetts, have invented an Improvement in Builder Motions for Spinning- Franies, of which the following description, in connection with the accompanying drawing, is a specification, lik characters on the drawing representing like parts.

This invention relates to improvements in builder motions for spinning frames especially of the type which are adapted to wind filling carriers provided with feeler slots near the base thereof.

In the Case of filling carriers of this type a feeler enters the slot in the filling carrier when the filling exposes the portion of the slot to be thus entered and this action is utilized to effect a change in the loom operation such as the replenishment of the shuttle with a fresh filling carrier. It is desirable therefore that a suiiicient amount of filling be wound upon the base of the filling carrier beneath that portion of the slot entered by the feeler to allow for one or more picks through the loom and a sufficient anchorage of the filling end on the filling carrier to prevent the filling end from being drawn OE and curled up during the last pick of the loom before transfer takes place.

The object of this invention is to provide means for laying the required amount of filling upon the filling carrier below the por tion of the slot to be entered by the feeler during an upward and downward preliminary traverse.

The object of the invention further is to lay upon the filling carrier below the portion of the slot to be entered by the feeler during the preliminary upward and clownward traverse substantially such an amount of filling as would be laid during a full or complete upward and downward traverse.

The object of the invention is further to provide means for adjusting the point in the first upward traverse at which the laying of filling upon the filling carrier shall begin.

These and other object of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

While the invention is applicable to various types of spinning frames it is shown in Patented Feb. as, 1918.

F ig. i is a top plan view of the parts shown in Fig. 3 with the frame omitted;

Fig. 5 is a *iew similar to Fig. 3 with the frame omitted and with the parts shown in position at the conclusion of the first upward traverse.

The general construction of spinning frames of the various types and of builder motions is so well known and familiar to those skilled in the art that no detailed description of the parts not immediately concerned with the present invention need be given. As already pointed out the invention is applicable to various types of spinning frames and for convenience of disclosure a spinning frame of the ring type is illustrated.

The frame of the machine comprises the side pieces the left hand one 1 of which is shown. The longitudinal ladder or box rail 2 extends transversely between the side frames and in it are mounted and driven the spindles 3 upon which are placed the filling carriers at. The usual lifter rail 5 upon which are mounted the rings 6 with their travelers is supported by the lifter rods one of which is shown at 7 and which are guided vertically in the ladder or box rail 2. Each lifter rod 7 is provided at the lower end with a foot piece 8 resting upon a roller 9 carried by an oscillating lever 10. The oscillating levers are connected by the rod 11 and the left hand lever 10 is connected by a chain 12 running over a sheave 13 to the builder motion. The builder motion acts to depress the lifter rail 5 by pulling upon the chain 12, the lifter rail being depressed by its own weight. As the builder motion lets off the chain 12 suitable weights connected with the levers 10 cause the elevation of the lifter rail 5. Thus the filling is laid on the filling carriers by an up and down traverse of the ring rail with respect thereto.

The builder motion illustrated is of a generally familiar type. It includes a builder cam 1% mounted on a shaft 15 and driven by suitable connections, not illustrated, in the direction of the arrows in Figs. 3 and 5. This cam cooperates with a follower 16 carried by a stud 17 projecting laterally from the builder arm 18 pivotally mounted at one end on a stub shaft 19 secured in the frame. The builder cam is provided with a plurality of lobes each of which acts to give a complete traverse to the lifter rail. One side 20 of each lobe acts to give the clownward traverse and the other side 21 the upward traverse.

A second or shifter arm 22 is pivotally mounted on a shaft 23 carried by the builder arm 18, a projection 24 extending from the opposite side of the builder arm to provide a suitable support for the said shaft. The pivot for this shifter arm is located intermediate the builder cam and the pivot of the builder arm. The free end of the shifter arm itself extends well beyond the free end of the builder arm.

The usual pick motion by which gain is imparted to the traverse is mounted on the shifter arm. This pick motion comprises a ratchet wheel 25 actuated by a pawl 26 on a carrier 27, the carrier receiving its motion from a rod 28 connected thereto and provided with adjustable collars 29 which engage a fixed portion 30 of the frame as the ratchet wheel and pawl carrier are bodily reciprocated vertically in the usual manner. The ratchet wheel 25 is mounted on the end of a shaft 31 journaled in bearings 32 and 33 depending from the shifter arm 22 and carries at its rear end a worm 3 1 engaging and operating a worm gear 35 mounted on the shaft 23. The worm gear 35 has attached thereto a drum 36. The chain 12 after passing over the sheave 13 passes down around a sheave 37 journaled on the shifter arm 22 at a point intermediate its pivot and its free end and then passes to the drum 36 to which it is attached and upon which it is wound up and let off by the pick motion in the usual manner.

The builder arm 18 is provided at or near its free end with a projection or lug 38 which extends laterally therefrom over the shifter arm 22. Hence when this lug 38 is in engagement with the top of the shifter arm any downward movement imparted to the builder arm is likewise imparted to the shifter arm, but upward movement of the builder arm may take place independently of the shifter arm.

The shifter arm at its free end has pivoted thereto at 39 and upstanding therefrom a latch 10 the upper end of which is shouldered as at 11 and d2 to engage the lower face 13 of the ladder or box rail 2 or other fixed portion of the frame. A foot piece it is connected with the latch 40 so that the operator by pressing his foot upon the foot piece ist may swing the latch 10 forward to bring either the shoulder d1 or the shoulder &2 beneath the face 13; in the former case the parts are in the position for doifing and in the latter case for the winding of the preliminary traverses forming the preliminary winding of filling. Normally the latch 40 swings rearwardly by gravity against the stop 15 into the position shown in dotted lines in Fig. 3. The latch is made adjustable as to its length and for this purpose is shown as made in two parts having their adjacent faces corrugated or roughened and locked together by a set screw 46 extending through a longitudinal slot in one or both parts.

In the operation of the spinning frame when it is desired to wind upon the filling carrier a preliminary winding of filling as at the base of the slot of a feeler slotted bobbin the operator places his foot upon the foot piece set and depresses the shifter lever 22-, which will then swing independently about the shaft 23 until the latch swings forward into the position shown in full lines in Fig. 3, that is, with its face i2 beneath the face 43 of the ladder. Then the operator lets up with his foot leaving the latch and shifter lever in the position shown in Fig. 3. The operator then brings the cam 1-1 to the position shown. in Fig. 3, that is, with the side 21 of a lobe in contact with the follower 16 near the peak of the lobe. It is desirable to have thecams so positioned that the follower 16 will be as near to the peak of the lobeas it can and allow the passage of the peak of the cam over the follower to depress the shifter arm and builder arm sufliciently to release the latch 40 from the face 43.

The winding operation will thus begin with an upward traverse, the follower 16 on the builder arm 18 riding up on the side 21 of the lobe of the cam thus allowing the builder arm to swing upwardly about its pivot 19. But as the builder arm thus swings upwardly it carries with it the pivot 23 of the shifter arm which now pivots about the pivotal connection 39 with the latch. This gives aslight upward movement to the sheave 37 and consequently to the lifter rail and at the conclusion of the upward traverse the parts are in the position illustrated in Fig. 5. Thus substantially the entire amount of filling which would be laid during an ordinary upward traverse is laid upon the filling carrier over a very small zone the limits of which are fixed by the comparatively small vertical movement of the sheave 37. In the continuation of the operation of the machine a downward traverse follows being given by the side 20 of the next lobe of the cam let and during this movement the parts move from the position shown in Fig. 5 back to the position shown .in Fig. 3. During this movement the builder arm 18 swings downwardly about its pivot 19 giving a slight downward movement to the sheave 3'7 until the projection 38 engages with the top of the shifter arm 22, and then during the continued rotation of the cam let the builder arm and shifter arm are depressed together and when the peak of the cam passes the follower 1.6 the latch i0 is released from the face l3 of the ladder 2 and the latch swings to the position shown in dotted lines in Fig. 3. During this downward traverse the full amount of filling which would be laid in an ordinary traverse is laid but in substantially the same restricted zone as that upon which the filling was laid in the first upward traverse. Thus a preliminary winding of filling such as shown in Fig. 2 is formed over a very narrow zone f? at the base of the feeler slot 48. Upon the continued operation of the machine, the latch l0 being now swung backwardly, the parts are in position for the main or service traverse and the winding proceeds as usual, the traverses now lengthening out to that caused by the full swing of the builder arm, the shifter arm being held up against the projection 58 by the pull on the chain 12.

it the conclusion of the spinning and winding operation and when it is desired to dofi the operator again places his foot upon the foot piece is: and this time depresses the shifter arm ufficiently to enable the shoulder ll of the latch it) to come beneath the face and be held thereby.

An adjustment such as that provided at .46 for the length of the latch l0 enables the point at which the first upward traverse shall begin to be determined with accuracy.

Having fully described my invention, what. I claim as new and desire to secure by Letters Patent is:

1. In a spinnin frame, a lifter rail, a pivotally mounted builder arm, means for oscillating said builder arm, a shifter arm pivotally mounted on the builder arm, means for preventing the shifter arm from moving above and permitting it to move below the builder arm. a let 0E motion comprising a connection extending from intermediate the ends of said shifter arm to the lifter rail, and manually operated means for positioning the shifter arm in nearly its lowern'iost position when the builder arm is in position just past the beginning of its upward movement whereby a restricted upward and downward traverse are imparted to the lifter rail during which substantially the entire filling for full upward and downward traverses are laid in a restricted zone. v 2. In a spinning frame, a lifter rail, :1 pivotally mounted builder arm, means for oscillating said builder arm, a shifter arm pivotally mounted on the builder arm, means for preventing the shifter arm from moving above and permitting it to move below the builder arm, a let off motion comprising a connection extending from intermediate the ends of said shifter arm to the lifter rail, a latch pivotally mounted at the free end of the shifter arm to engage a fixed portion of the frame and manually operated means for positioning the shifter arm in nearly its lowermost position when the builder arm is in position just past the beginning of its upward movement whereby a restricted upward and downward traverse are imparted to the lifter rail during which substantially the entire filling for full upward and clownward traverses are laid in a restricted zone.

3.
