Abstract: 11,316. Sykes, E. May 7. Winding - machines; s t o pmotions.-Each winding-head comprises a casing 1, Figs. 1 and 6, through which passes the driving-shaft 4 on which is journaled a sleeve 13 carrying a clutch boss 18 driven by a member 19 slidable. on and rotatably connected with the shaft 4. The clutch member 19 is moved into frictional engagement with the boss on the sleeve 13 by turning up a lever 32, Fig. 9, fixed on a rod 22 journaled in a bracket 24 and having an eccentric pin 21<1> which engages with a groove in the member 19. The sleeve 13 drives the winding-spindle 16 and traverse bar 6 by bevel and helical gearing, as shown. The bar 6 has an extension 8 in which is journaled a bowl 9 engaging with a fixed cam 10 by which the bar is traversed; a spring 11 maintains the bowl in contact with the cam, and a spring 10<1> forms a yielding bearing for the bar 6. The bar 6 is screwed and loosely carries a notched disk 25, the hub 25<1> of which is cut away to admit a segmental nut 26, Fig. 4, carried by a clamp 27 and normally held in engagement with the threads 6' by a spring 28 so that the disk rotates and reciprocates with the bar. An arm 29, Fig. 3, having a forked portion 29<1> which engages with a vertical guide track 5<3> on the bracket 5, is loosely supported by ball bearings on the boss 25<2> of the disk, and a side extension 29<2> carries a pivotal thread-guide 30 having an eye 30<1> and an arm 30<2>, which is normally adjacent to but clear of the notched disk. The yarn, after passing through any suitable tension device and under a detector wire 33, passes through the eye 30' and is laid on the bobbin 17, the disk 25 being lowered on the bar 6 to commence winding at the butt end of the bobbin by pressing inwards the clamp 27. As the eye 30' comes opposite the full diameter of the butt end of the bobbin, it is moved outwards, and the end 30<2> engages with the notched disk 25 and retards its rotation, so that it is raised slightly on the screw and the point of commencement of the next layer is raised at the end of each traverse. When winding on paper tubes, or tubes without a tapered end, a cam surface 44, Fig. 3, is provided on the bracket 5 and is so located that during the winding of the lower part of the cop a finger 45, pivoted to an extension on the arm 29 and normally held with its end 45<1> out of contact with the disk 25, is caused to wipe over the cam, and at each vertical movement to swing the end 45<1> into engagement with the disk 25 and. to hold the same intermittently in order to give the required build to the bottom of the cop. When the full diameter of the cop is attained, the pivoted finger 30<2> commences to act as above. The detector wire 33 in on a dagger 34 pivoted to a lever 36, and on the breakage or failure of the thread the dagger falls into the path of a spring pin 18<1> reciprocated by a swell 18<2> on the clutch 18 and is forced endways and rocks the lever 36 to withdraw a projection 36<1> on the lever from a notch 37' in a disk 37 fixed to the rod 22, which is then rotated by a spring 22<1> to throw the clutch out of gear. A spring 38 acting on the lever 36 tends to keep the projection 36' in engagement with the disk 37. On the completion of a bobbin or cop, the arm 29 moves an arm 41 on a rod 40, connected to the lever 36, upwards, and actuates the lever to free the disk 37 and stop the winding-head. In a modified construction of stop-motion for stopping the winding-head on the breakage or failure of the thread, the dagger is pivoted to an arm fixed to and passing through a fixed spring plate, the spring plate acting normally to hold the end of the arm in engagement with a notch in the disk 37; when the dagger drops, it is forced endways as before, and the disk is released to bring about the stoppage of the head.
