Title: Improvements in and relating to spinning mules and twiners
IPC: D01H3/12
Filed: 1931-02-13
Abstract: 362,244. Spinning-mules. LEES & CO., Ltd. A. and GUY, W., Soho Iron Works, Oldham. Feb. 13, 1931, No. 4529. [Class 120 (ii).] In a spinning-mule of the kind having in addition to the ordinary shaper rail a second rail for use during the winding of a bunch at the base of the cop, the fixed bunching rail 10 serves to hold the cop building-motion out of action during the winding of the bunch, it being automatically brought into action after the bunch has been wound, the bunching motion then being inoperative. The bunching rail 10 is adjustably mounted in two chairs 11, 12 parallel to the shaper rail 17, and a lever 6 pivoted at 7 and a latch 8 pivoted at 9 are mounted on the carriage slide-block 3 in addition to the trail bowl 4 and faller bowl 5. The latch 8 is connected by a link 18 to a side-lever 19 pivotally mounted at 20 on a bearing bracket 21 in which is also mounted a shaft 22 carrying a ratchet wheel 23 and a boss having a cam-part 24. A projection 27 is formed on the blank part of the ratchet wheel 23 adapted to engage in one direction a setting bracket 28 and in the other the lever 19. A lever 29 carrying a pawl 30 adapted to engage the ratchet wheel 23 is mounted on the shaft 22 while a rod 32, vertically adjustable by means of nuts 33 on its screwed end, engages the lever 29. In winding a bunch the latch 8 is engaged by the lever 6 at the beginning of the inward run. During the inward run the trail bowl 4 travels along the shaper rail 17 for a short distance until the lever 6 begins to travel along the bunching rail 10 lifting the slide block 3 and with it the bowl 4 off the shaper rail 17, as shown. On the outward run the rod 32 is lifted by contact with an inclined weighted lever 35 and raises the lever 29 and pawl 30 thereby rotating the ratchet wheel 23 against a spring 26, the wheel 23 being held by the check-pawl 31 as the rod 32, lever 29 and pawl 30 fall back. On the inward run the lever 35 turns idly on engagement with the rod 32. These actions are repeated until the projection 27 on the ratchet wheel 23 engages under and lifts the arm 19, the latch 8 being thereby released from the lever 6 which then pivots idly, the bowl 4 engaging the shaper rail 17 to build the cop. On releasing the pawls 30, 31 the ratchet wheel 23 is returned by the spring 26 to its initial position as set by the adjustable bracket 28. The cam 24 is used to operate the quadrant so as to fasten the governor motion slightly during the bunching operation.
