Abstract: 709,679. Counting-apparatus. CELANESE CORPORATION OF AMERICA. June 3, 1952 [June 5, 1951], No. 13983/52. Class 106 (1). [Also in Group IX] In the operation of a slub detecting and counting device a running yarn is passed through pigtail guides 2 and 5 and a slot in a slub gate 3 slidably and removably mounted in a holder 13. When a slub, as at 30, is unable to pass through the slot, it causes the gate 3 to rotate around a shaft 17 against the action of a spring 24 ; corresponding rotation of a spring pawl 15 rotates a ratchet wheel 18 on the shaft 17 so actuating an indicating hand which co-operates with a numbered chart to register the stub count, Fig 2 (not shown): After the slub has rotated the holder 13 to the position shown in dotted lines, the slub is rejected and rides over the top of the gate 3, the yarn resuming normal travel through the slot and the holder 13 being returned to its original position by the spring 24. Reverse movement of the wheel 18 is prevented by a detent 29 engaging therewith. Pivotal movement of the gate is limited by adjustable stops comprising an eccentric 21 and a set screw 25. The spring 24 may be replaced by a coil spring one end of which passes through a hole at the base of a leg 16 of the holder 13, the other end being anchored, Fig. 5 (not shown).
