Abstract: 712,851. Winding thread. REINERS, W. Jan. 2, 1952 [Jan. 9, 1951], No. 148/52. Class 120(2) Thread winding apparatus is provided with means controlling the operation of a plurality of automatic devices carrying out different parts of the winding operation during different portions of one cycle of the control means, and also with a plurality of automatic, releasable connecting means attached to the automatic devices for connecting or disconnecting the same from the control means so that the latter may operate only one of the automatic devices during a cycle. Thread F from the supply bobbin 15 carried on a pin 23 supported on a spring-urged rotatable bellcrank lever 25, 26, is led over guides 16, 17, through a tension device 19 and a clearer 20, thence over a guide 22 to the traversing and driving drum 2 of the thread package 3 carried on a lever 4, 6 pivoted at 5 and counterweighted at 7. When the package reaches a pre-determined size, the movement of the lever 4, 6, makes a circuit through contacts 11, 12 to energize a solenoid 14 and rotate a lever 47, 48 about its pivot 46 to grip and break the thread in the clearer 20. The breaking of the thread permits a lever 21, 50 to fall and make contacts 51, 52 to complete a circuit to energize a solenoid 55 and remove a detent 57 from a notch 58 in a disc 59 to allow a cam shaft 60 to begin to rotate through a single revolution. The cam 63 on the shaft 60, will actuate a lever 113, 114 which, in the position shown in Fig. 1, will merely rock about its pivot 116, but, if there were no supply of thread between the bobbin 15 and the thread tensioner 19, the rod 18 would fall to turn a lever 41 and bring the hook 45 of the rod 44 into the path of the end 117 of the lever 114. In that event, the spring-urged lever 30, 31, 32 would be swung about its pivot 20 to tilt and then remove the empty supply bobbin 15 from the pin 23 and open a gate 39 in the feed hopper 37 to allow a fresh supply bobbin 15<SP>1</SP> to fall into a shoot 35 and position itself upon the pin 23. The thread F' from each fresh supply bobbin 15<SP>1</SP>, as it is contained in the hopper 37, is arranged, by hand, to extend to a suction tube 38, so that as the fresh bobbin 15 is positioned in the pin 23, the thread F' comes under the influence of the mouth 83 of a suction tube 82 whereby the thread may be carried to a knotter 85. Following the operation of the cam 63, the cam 65 moves the lever 69, 71 about its pivot 70 to move racks 73, 75, which rotate suction tubes 77, 82 to bring the ends of thread to the knotter 85, the end of thread on the package having been made available by a reversal of the direction of motion of the drum 2 causing a slight unwinding of the package 3. During the growth of the package 3, a rod 9 had raised the lever 91 so that the hooked end 93 thereof had come within range of the end 102 of the lever 101 so that when the cam 62 moves the spring-urged rod 96, the lever 101 swings about its end 102 to rock the spring- urged lever 105, 106 about its pivot 107 to feed a fresh empty winding-on spool from the supply shoot 112 into position to be taken up, in the winding position; on the supporting lever 4, 6.
