Abstract
1,244,321. Wheel detector. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 22 May, 1969 [7 June, 1968], No. 27145/68. Heading B7N. Contact members 3, 4 replace the running surface 1 of a rail over a distance of approximately 3 inches and when short-circuited by a rail vehicle wheel complete a signalling circuit indicating vehicle presence. The contacts are insulated from each other by layer 9 and are secured by bolts 5, 6 to a guide block 10 which is grooved 11, 12 to receive tongues 13, 14 of fish plates 15, 16. The guide block allows vertical movement of the contacts which rest on a resilient neoprene pad. The belts run in insulated bushes 7, 8 and act as the circuit terminals. The arrangement may be used to signal the correct positioning of mine cars in a cage.
