337,850. Green, A. Aug. 15, 1929. Winding-machines; stop-apparatus, non-automatic.-In a machine such as described in Specification 326,786 or in machines for winding cops of yarn or thread, wherein the spindles are frictionally driven, the thread guide is carried by an arm 9, Fig. 3, which is frictionally held on a rotatively oscillating shaft 10 and which is advanced round. the shaft 10 by impacting against a progression wheel 19. The winding spindle 3, which may carry a tapering tube 4, Fig. 5, is driven by friction discs 5, 7, a friction washer 3c being pressed against a collar 3b by a spring 3a. The progression screw 17 is spring mounted eccentrically in a bush 2d in which it is held in operative position by an arm 17m having a sleeve fitted over the spindle 3. When the cop is wound, the arm 17a is withdrawn from the spindle and rotated half a turn in the bush 2d, thereby moving the screw 17 and wheel 19 away to allow the cap to be taken off. The screw 17 may have rather more than half its thread cut away along the whole length to enable the wheel 19 to be slipped back to the starting position. For removing the cop, the spindle 3 and delivery are stopped, a rod 20, connected with a rod 20b, is moved upward by a hand-operated stop-motion, the friction disc 7 and thel spindle 3 being moved in its bearing 2, away from the driving disc 5 by a projection 20c acting on the disc 7 and against the pressure of a spring 8; the delivery being stopped by a stud 20d engaging an arm 16a of a lever pivoted at 16c and forcing the de,- livery roller 16 away from the roller 15a against which it is normally pressed by a spring 16b. The traverse arm shaft 16 is oscillated by a cam driven by a chain and gearing from the driving shaft, the cam rocking an arm fixed to the shaft 10. The wheel 19 may have a tyre 19a of rubber, leather & c.
