Abstract: 264,443. Universal Winding. Co., (As signees of Anderson, J. A.). Jan. 14, 1926, [Convention date]. Stop - motions; stopapparatus, non-automatic; thread -guides.-Relates to machines for winding yarn, thread, and the like, of the kind comprising a measuring-device actuated by the draft of the yarn and adapted to operate means to stop the machine when a predetermined length of material has been wound, and a controlling-member adapted to start the machine and to reset the measuring - device. The controlling-member is so arranged that it effects the resetting of the measuring- device before it effects the starting of the machine; a stop-control lever engaged by a cam disc and adapted to operate it at predetermined points of rotation of the disc to stop the machine is arranged to release detent means which normally maintains the controlling-member in position to continue the operation of the machine; and the controlling-member may be provided with pedal-operated means so as to leave the operator's hands free. The invention is shown applied to a machine designed particularly for winding small packages of embroidery yarns, sewing silks, mending cotton, or the like, the yarn passing from supply bobbins B, Fig. 1, through guides 15, 17 and a tension device 13, around a measuring-wheel 43 and through a slotted guide 11 provided with a guard 12 to the winding-spindle 7. The controlling-member comprises a crank arm 33 pivotally mounted in lugs 31, Fig. 5, on a lever 20, which, in known manner, controls the spindle clutch, and is maintained in operative position during winding by a latch 27 on a detent lever 23. The crank arm 33 is normally held in the position shown in full lines in Fig. 5 by a spring 37 and is connected to a treadle 85 by a wire link 87. The measuring- wheel 43 is mounted on a shaft 44 carried in bearings, which are vertically adjustable so that a worm 48 on the sraft gears with one or another of gear rings 47 on a wheel 48 which drives a cam disc 55 provided with a number of notches 58 By adjusting the bearings of the shaft 44 and by using discs having different numbers of notches the machine may be adapted to wind different lengths of material. The notches 58 are adapted to be engaged by a roller 60 carried by one arm 65 of a stop-control lever 62, the other arm 66 extending downwardly by the side of the crank arm 33. The arm 65 is connected by a rod 68 with the detent lever 23, and an ear 80 on the arm 66 is provided with a slot 79 whereby a lost-motion connection is made by means of a link 78 with one arm of a three-arm lever 75, which is provided with a brake 74 for the measuring-wheel and is connected by a spring 70 with the lever 62. When the machine is stopped, the roller 60 is engaged in one of the notches 58 and the brake 74 applied; upon operating the treadle 85 the crank arm 33 is rocked against the spring 37 and its outer end swings against the arm 66 of the lever 62, whereby the roller 60 is withdrawn from the notch in the disc 55 and continued movement of the lever 62 operates the lever 75 and withdraws the brake 74. When the crank arm has moved so that its hub abuts against the hub of the lever 20, further movement of the treadle moves the lever 20 about its pivot so that it is engaged by the latch 27 and the spindle clutch connected. When the next notch 58 registers with the roller 60, the lever 62 is operated by the spring 70 and releases the levers 23, 20 to disconnect the spindle clutch and apply a brake 21 to the spindle, and, the pull on the link 78 being released, the lever 75 is rocked by the spring 70 to apply the brake 74.
