Abstract

494,453. Electric switches. ROOK, J. A., and ROOK, C. H. Oct. 21, 1937, No. 28702. [Class 38 (v)] [Also in Group XXXVIII] A signalling circuit on a vehicle is completed by the movement of the throttle or other control towards closing position through the medium of a lost-motion switch consisting of a spring- pressed circular block 6 having a radial slot 7. In this slot is an arm 14 fixed to the shaft 5 connected with the control mechanism. On the lower face of the block is an interrupted conducting ring 8 having one end turned into the slot. When the accelerator is pressed the arm engages the insulating side of the slot and entrains the block with it against the friction between the block and a fixed plate 10 connected to the lead 12. If the accelerator is released the arm moves over to the other side of the slot and completes the circuit to the signal lamp by engaging the turned-in end of the ring.
