362,641. Electric stop motion for gill spinning frames. SCOTT, W. J., 78, Collins Street, Woonsocket, Rhode Island, U.S.A. Nov. 18, 1930, No. 34673. [Class 120 (ii).] In a gill spinning frame having sliver draft rolls and a spindle carrying a winding spool a stop mechanism, including a member adapted to be moved by abnormal sliver thickness, is mounted between the draft rolls and the spindle. Each sliver 21 passes through draft rolls 22, a comb 23, and a second set of draft rolls 24, 25, through the spacer frame 28 which carries the stop-motion control members and over a roller 29 to a spindle 10, guide eye 14, flyer arm 15, and bobbin 16. The bobbin rests on a drag washer 17 on the lifter plate 18 reciprocated by the mechanism 19, 20. The spindle is driven through pulleys 11, 13 and the belt 12. The spacer frame 28 comprises a bar 30 on which are mounted vertical slotted member 31, and a spacer member 36 the ends of which move in the slots in the member 31. The member 36 is held in a desired position relative to the bar 30 by bolts adjustably positioned in the slots 31. A contact pin 39 is connected to the spacer member 36 so that the occurrence of an abnormal sliver thickness rocks the member 36 and causes the contact pin 39 to engage a second contact pin 43, mounted on one of the members 31 but insulated therefrom, to complete an electric circuit. The completion of the circuit energizes an electromagnet which attracts to it an armature plate thereby freeing interengaging latch and catch members so that an operating lever normally held by the latch and catch members in inoperative position may move under the influence of a spring to shift a driving belt from a fast to a loose pulley.
