Abstract
773,641. Making cables; stop motions. HEGGEN, O. Sept. 13, 1955, No. 26156/55. Class 109. [Also in Groups XXVII, XXIX, XXX, XXXIV and XXXVII] A motor 23 driving a cable twisting machine for twisting strands 17 into a cable 171 is stopped in the event of a strand breaking by the operation of an electric switch 20 rotating with the strand roller 18. The switch 20 (see Group XXXVII) closes its contacts upon cessation of rotation to energize an electromagnet 21 and open the motor supply switch 22.
