Abstract

739,048. Pulleys. JUTE INDUSTRIES, Ltd., and PLENDERLEATH, J. S. Nov. 14, 1952 [Aug. 11, 1951], No. 18965/51. Class 80 (1). [Also in Groups IX and XXXVII] A pulley 2 mounted by a ball bearing 3 on a base 4 intended for attachment to a shuttle of a circular loom, and having a groove 6 for receiving the yarn whereby it is rotated, is provided with three radial passages 11A spaced at 120 degrees accommodating mercury tube electric switches 11 (see Group XXXVII), the switches completing or breaking a circuit depending on the centrifugal forces acting thereon. The head 16 of a hardened steel pin 15 engages a carbon block 14 under the tension of a spring 18 received in a nut 15A, and produces a frictional drag. Holes 28 in the groove 6 provide for good grip of the yarn, and hard steel may be sprayed on the groove.
