Abstract: 514,855. Winding yarns. KINSELLA, E. May 17, 1938. No. 14712. [Class 120 (ii)] An. automatic machine for winding yarn into cheeses comprises drum means for driving a cheese at the winding position, means for doffing a completed cheese by withdrawing it from the winding position-and for doffing a cheese carrier by transferring it into that position and means for engaging the thread between the completed cheese and the traversing thread means and, carrying it into engagement with the cheese carrier being transferred to the winding position. As shown, the carrier or support 3, Fig. 6, for the cheese being wound is driven and supported by a pair of drums 1,2 carried by shafts 16, 17 extending along the machine and serving a number of winding units which are associated with an artificial yarn spinning machine 100, Figs. 1 and 2; there are two sets of shafts at each side of the machine serving two banks of winding units, one above the other. An empty cheese support 7 is, during winding, supported in arms 8 above the drum 2 and after a predetermined length of yarn has been wound on the support 3, slides 6 at the sides of the winding unit are moved towards the arms 8 so that points 62 on the slides move below the spindle 64 of the support 7 and pivoted spring catches 65 also on the slides move below the spindle 4 of the wound package 66. The slides 6 then move away from the arms 8, the package 66 being drawn over on to the drum 1 and continuing to rotate and the support 7 being raised and allowed to -fall on to the drum 1 which begins to rotate it; at the end of the movement, the completed package 66 falls on to supports 10 and an arm 13, supported by a pivoted guide 72 and carried by a lever 70, is moved to carry the thread, extending from the package 66 to the traversing thread guide 11, over on to the rotating support 7 which is now supported and driven by the two drums 1, 2 and which has a central roughened portion which picks up the thread and breaks it at the package 66. The slides 6 are carried by screwed rods 14 engaging interiorly threaded helical gears 45 driven by gears 44 on a shaft 43 driven by chain and sprocket gearing from a shaft 40, Fig. 7; the end 69 of one of the rods 14 is cam-shaped and engages a nose on the lever 70 for actuating the arm 13. The shaft 40 is driven alternately in opposite directions through clutches and gears meshing with gears on a shaft 32 driven by reduction gearing 30 from a magnetic clutch 29 caused to engage a shaft 26 which is driven slowly from the waste roller shaft 78 of the spinning machine which also drives the drums 1; 2 and traverse cams 21. The initiation of the drive to the shaft 32 is controlled by gearing and a switch in a box 15, Fig. 9, driven from the shaft 18 and after the gearing has been driven for a predetermined number of revolutions, i.e.. when the' requisite length of yarn has been wound on each package being wound, the switch is closed to complete a circuit through a solenoid 74 and close a switch 60, a second solenoid then closing a high tension switch 77 in the circuit of the transformer 61 and the magnetic clutch 29 which is then engaged with the shaft 26 to rotate the shaft 32 and cause the shaft 40 to rotate and so actuate the slides 6 by reason of the clutching of one of the pinions 35, 38 loose on the shaft 40 with the clutch member 46 keyed thereto. The clutch member 46 is engaged by a fork 54 on a lever 52 connected to a crank 47 driven slowly from the shaft 26 so that during one revolution of the crank the clutch member 46 is shifted twice to reverse the direction of movement of the slides 6 and, at the end of the revolution, the clutch 29 is disconnected to bring the slides 6 to rest by a switch 59 which is actuated by a cam 58 on a shaft 158 driven from the shaft 26 at the same speed as the crank 47, the switch 59 short circuiting the switch 60 and breaking the circuit in the transformer 61 actuating the clutch. The position of the clutch member 46 is sharply changed by a toggle spring 53 connected the lever 52 and a lever 56 and toggle spring 57 hold the member 46 in one position or the other while lost motion of the fork 54 is taken up. The traverse guides 11 are reciprocated by cam 21 at the ends of the machine driven from a shaft 19 driven from the shaft 18, the chain drive 118 between the two shafts being deflected to vary the speed of the shaft 19 and break up any ribbon winds by jockey sprockets on a rocker bracket 24 pushed on the shaft 19 and actuated by crank lever gear 22 driven at a slow rate from' the shaft 18. The drums 1, 2 are driven through clutches so that they may be brought to rest independently to remove any waste caught on them, each drum being loose on its shaft 16 and having an end spider 81 with dogs forced by a spring 78 into engagement with dogs 80 on a disc'82 pinned to the shaft 16. A sleeve 84 adjacent the disc 82 has a quick start thread 85 engaging a member 86 secured to the machine framing and by rotating the sleeve a friction disc 89 thereon engages a surface 90 on the spider 81 and moves the drum out of driving engagement with the disc 82 and brakes it, the other end spider 94 of the drum also engaging a friction surface 93 on another sleeve 91 fixed to the frame; the sleeves may be concave so that any waste may be slid on to them for subsequent removal. The empty cheese carriers may be supplied automatically from a magazine and the completed cheeses allowed to roll or slide away after each doffing and donning operations.
