Abstract

257,497. Joyce, J. D. April 28, 1925. Winding - machines; spindle-driving arrangements. - In a winding- machine, as described in Specification 257,315, bunch - building means control the traverse of the thread until the bunch reaches a predetermined thickness. The drive shaft 1, Fig. 1, drives a countershaft which is journaled in a casing 1<a>, and carries a cam which actuates rock-shafts 8. Friction-wheels 9 on the shaft 1 drive wheels 10 slidably keyed to shafts 11 which carry cop-spindles 12. An arm 20, Fig. 1, which is rocked by the shaft 8 through a clutch 17, reciprocates a bar 22 which actuates bars 23, 24, the former of which carries a sharer plate 26. A screwed rod 25, Fig. 6, slidably pivoted at one end 82, is pivoted to slide laterally at its other end in a slotted plate 28 on the rod 24. On the rod 25 is mounted a thread guide carrier 90. an arm 87 on which is held in engagement with the shaper plate 26 by a spring to govern the lateral position of the rod 25 about the pivot 82. The carrier 90 is mounted on a sleeve 93, Fig. 6, on the rod 25. On a disc 95, rotatably mounted on the sleeve 93, is pivoted a carrier 97, in which is journaled a worm 98 spring-held in engagement with the screwed rod 25. A spiral spring 102 wrapped tightly round the worm-spindle 99 and fixed to the carrier 97 prevents rotation of the worm in one direction, so that, when the disc 95 is frictionally rotated by the cop, the worm 98 feeds forwards the carrier 90 on the rod 25. To return the carrier 90 to initial position, the worm 98 is raised from the rod 25. In starting a cop, the yarn passes through one of two thread-eyes 14a, 14<b> to the thread-guide 15 on the carrier 90, and then over a pin 16 to the spindle 12. The pin 16 is fixed to a plate 30 which is universally pivoted to a slotted frame-plate 37. The yarn is made to form a bunch at the base of the spindle 12 until the plate 30, which engages the underside of the wound yarn, is depressed sufficiently for a lug 35 thereon to enter the slot in the plate 37 under the influence of a spring 38, so that the pin 16 releases the yarn, which thereupon partakes of the usual motions of the thread-guide 15 to build up the cop.
