Abstract: 8340. Kohlbrenner, G. April 10. Spooling-machines, t h r e a d; winding - machines. -The machine, provided with an automatic s p o o l feed, is shown as designed for winding spools for ribbon weaving, but may be adapted also for winding sewing-machine and other spools. The material is drawn from a spool on a pin 107, Fig. 1, over a tension device 61, Fig. 3, secured to the adjustable bars 58 constituting the magazine for supplying the empty spools, and is laid on the spool 44, Fig. 1, by a thread-guide 18, 19, Fig. 2, which is reciprocated by a link 21 from a pivoted lever 13 oscillated by a heart-cam 11 driven by worm gear 7, 10 from the main shaft 4. For cross-winding, the heart-cam is replaced by an eccentric star-cam. The spool is held between a head 38 on the shaft 4 and the ribbed face of a head 41 on a pin 40 mounted in a sliding head 45 which is constantly pressed forward by a spring 51 embracing the end of a rod 50. The worm 7 also gears with a worm-wheel 22 secured to a cam 23 with an acting periphery 109, and a part of the circumference of the wheel is cut away to receive a loose piece 28, Fig. 7, pressed outwards by springs 27 but normally depressed to disengage the piece 28 from the worm by a pivoted lever 32, Figs 2 and 3, carrying an adjustable set-screw 34. On the completion of a spool, the outer layer pushes back a feeler plate 105 so as to move the lever 32, thereby releasing the piece 28 for the worm-wheel to be driven. A cam 24 fixed to the wheel then operates a lever 55 to press back the rod 50 and thus the head 45, the filled spool falling into the box 84 below. During this movement, a projection 78, Fig. 1, on the head 45 turns a catch-lever 75, Figs. 2 and 3, clear of a V-shaped notch in a plate 74 and also opens a knife 83 working with the notch, and a pin 103, Fig. 1, on the rod 50 acts through a pivoted piece 102 and a crank 100 so as to turn over a cover 98 for holding the fallen spool in the box 84. The cam 109 next acts on a pivoted lever 110 to tilt the lever 13 and move the guide 18, 19 so as to carry the thread or ribbon beyond its usual traverse and across the ribbed head 41, and finally, after the head 45 has been fully pressed back, the cam 23 operates a lever 70 with a toothed segment to actuate the forked grippers 65, Fig. 3, which carries the bottom spool from the magazine 58 into position between the heads 38, 41. The continued rotation of the wheel 22 permits the return movement of the head 45 to hold the fresh spool and grip the thread between the spool and the head, that portion of it extending to the full spool being carried into the V-notch in the plate 74 by the return movement of the catch-plate 75, and then cut by the return movement of the knife 83. As the head completes its inward movement, the pin 103 turns back the cover 98, which acts through a combination spring-lever 94, Fig. 1, to move a spring-controlled slider-plate 89 so as to allow the full spool to fall out of the machine. Finally, the gripper is returned to its original position and the worm-wheel 22 disengaged from the worm by the lever 32 depressing the loose piece 28. The fresh spool is being wound throughout these latter operations.
