BUILDER MOTION-F93 WINDING MACHINES.

Application filed March 12, 1923. Serial No 624,464.

To all 1071 01m it maxy comer n:

Be it known that 1, JOHN LiNnsAY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a Builder Motion for finding ltflachines, of which the following is a specification.

This invention relates to yarn winding machines, and more particularly to builder motions for such machines, the object of the invention being to provide a builder motion which ceases to operate automatically upon the breaking of the yarn, the invention further residing in the provision of the novel and improving features hereinafter fully set forth.

In the attached drawings:

Figure 1, is a transverse fragmentary section of a portion of a winding machine;

Fig. 2, is a plan view'of that portion of the winding machine shown in Fig. 1;

Fig. 3', is a vertical section on the line 3-3, Fig. 2;

Fig. 4, is a section on the line 44, Fig. 3, and

Fig. 5, is a section on the line 55, Fig. 2.

VVith reference to the drawings, 1 designates one end of the main frame of a winding machine which supports a table 2, upon each end ofwhich is mounted a standard 3. Extending between these standards 3 the present instance, a pair of

tubular rods

4,4, which support bracket arms 5, which carry the reels 6' from which theyarnis fed to the spools. The spools 7 are each carried by a vertical shaft 8 mounted in suitable bearings in the main frame and having thereon a grooved pulley 9 which is connectejdby means of a belt 10 with a pulley wheel 11 on the main drive shaft 12, the latterbeing connected with 'a suitable source of power (not shown). The shaft 12 also carries a pinion 13 which meshes with a gear wheel 14 on a shaft 15 mountedin the frame, this shaft also carrying a pinionl6 which meshes with a gear 17 on a'cam shaft 18. The shaft 18 carries at each end of the frame of the machine a cam 19 which in each instance is engaged by a cam roller 20 on a frame 21 which is vertically reciprocable in the main frame of the machine. The frame 7211s, in the present instance, counterbalanced at each end by a'we'ight 22- connected is, in.

with the frame by a chain 23 which passes over a suitable roller 24' on a short shaft 25 secured in the main frame.

The frame 21 carries at each end a vertical rod 26 which is slidabl'e in

guides

27, 27, on the main frame, the rods 26 supporting'at their upper ends a cross bar 28, upon which are mounted the builder motions for'the various spools.

The separate builder motions'compiise a bracket 29which is secured to the cross bar 28, and which has therein a bearing 30 for a vertical, threaded shaft 31,,a collar 32secured to the shaft 31 maintaining the. shaft in the bearing 30, A second collar 33 is secured to the bottom of the shaft, and'interposed between this collar 33 and the bearing 30 is a'horizontal arm 34'which is loosely mounted on the vertical shaft and which carries a pawl 35 naintained by means of a spring 36 in contact with the teeth of a ratchet wheel 37, which is fixed to the said shaft 31 and which lies between the arm 34 and the bearing'tO. p 7

' A coiled spring 38 is secured to the arm 34 and to a pin 39 on the bracket 29, said spring tending to maintain the arm 34 in a predetermined position and returning it to this position when the arm is oscillated on the shaft in a manner to be described hereinafter. A spring detent 40 upon the bracket 29 bears against the ratchet 37 "and acts as a damper preventing returnmotion of the ratchet and any motion beyond that given by the pawl 35 I g Adapted to travel on the threaded portion of the vertical shaft 31 is a carriage consisting of a ratchet wheel41 having a down-- wardly extending hub 42,to which secured in such manner as to permit free rotation of the hub therein an arm 43, said'arm hav ing a rearward extension '44 through "which extends a vertical rod'45 which is fixed in an arm 46 off the bracket 29, this rod constituting a guide for the carriage and preventing rotational movementaround' the shaft31 of the arm 43. At the forward end of the arm 43 is a receptacle 47 which carries at each end a porcelain guide element 48', 48, and felt

pads

49,49, the purpose of which will be describedhereinafter.

The receptacle end ofthe 'arm 43 also cartil ries at the top and pivotally secured to a lug thereon a detent 51 which is adapted to engage the teeth of the ratchet 4:1 and which carries a wire rod 52 which extends in a substantially horizontal position over the center portion of the receptacle d7. A suitable recess 53 is provided in the outer wall of the receptacle 1? to permit down ward movement of the arm 52 sufficient to carry the detent 51 clear of the ratchet 11.

Pivot-ally secured to the top of the ratchet 41 by means in the present instance of a screw 54; is an arm 55 which is threaded at its center portion to correspond with the threaded portion of the shaft 31, and the arm 55 is retained in an advanced position with the threads thereof in engagement with the threads of the shaft 31 by means of a sprin 5o which is confined between the back of the arm 55 and a lug 57 on the said ratchet wheel. A pin 58 on the ratchet wheel limits the forward movement of the arm 55 towards the shaft 31.

Secured to the rear side of the receptacle portion 4:7 of the arm 43, one at each end thereof, is a porcelain guide 59 and (50 1e spectirely which extend upwardly and over the opposite ends of the receptacle.

The operation of the device is as follows:

The yarn is wound from the reel 6 onto the spool 7 in the usual manner, the latter being rotated from the main shaft 12 through the belt 10 and. the pulleys 11 and 9. The yarn in passing from the reel to the spools is led downwardly and under the guide 60, across the top of the receptacle, and under the guide 59, the guide 60 being hooked at the ends to prevent lateral displacement therefrom of the yarn. Between the

guides

59 and 60 the yarn passes under the arm 52 of the detent 51, the normal tautness of the yarn being sufficient to maintain the detent in engagement with the ratchet wheel ll. he felt pads 4E9, 419, in the receptacle 47 may be oiled for the purpose of oiling the yarn as it passes thereover.

During the normal operation of the machine, the frame 21 is reciprocated vertically in the main frame of the machine by the cams 19, such reciprocation being transmitted to the builder motion through the rods 26. At each downward movement of "the builder motion, the arm Set is brought into engage ment with a cam 61 adjustably mounted on the table 2, this cam forcing the arm in the direction of the arrow, Fig. 1-, against the tension of the spring 38, and through the pawl 35 turning the ratchet ST through a predetermined angle. Movement of the ratchet 37 carries with it the shaft 31, and through the threaded arm 55 efiects a movement of the carriage 4143 upwardly on the shaft. In this manner, while the entire builder motion is reciprocated opposite the spool 7 the rider is gradually fed upwardly 011 the shaft 31, with the result that the yarn is built up evenly upon the spool 7 after the well known manner.

In the event of the yarn breaking, the arm 52 of the detent 51, which normally is supported by the yarn, will drop downwardly and retract the detent 51 from the ratchet all, thereby permitting rotation of the ratchet 41 with respect to the arm 13. As a result of this free rotation of the ratchet 41, the upward feeding of the carriage on the shaft will be interrupted, the ratchet 4E1 merely turning with the shaft 31 as the latter is actuated by the cam 61. By reason of this interruption of the building action upon the breaking of the yarn, the operator is permitted to mend the break and restart the winding operation at the exact point that it was left off, the evenness of the winding on the spools thus being preserved.
