Abstract

726,952. Road tragic signals on vehicles. O'SHEI, W. E. Sept. 23, 1953 [Sept. 23, 1952], No. 23826/52. Class 118 (2). A semaphore arm indicator 1 is moved by means including a piston 9 movable in a cylinder 4 under the influence of compressed air, the piston-rod 6 extending through an aperture in the end wall of the cylinder and a packing member 15 on the piston serving to seal the aperture at the end of the piston stroke which raises the indicator 1, a spring 19 being provided to return the piston when the compressed air is released. The rod 6 bears a fork 7 engaging with a pin 8 on the semaphore arm. Contact springs 24 and 25 on the supporting bracket and arm 1 respectively complete a circuit for a lamp on the arm when the latter is raised. The control valve for the compressed air supply includes a shaft 31 with an actuating knob 38, the shaft having flats 32 co-operating with spring levers 34 for holding the valve in each of its operating positions. The valve member 41 rotates over a surface containing three ports and is provided with a sealing gasket 42, compressed air being admitted above the valve by connection 45. The two outer ports are each connected to the actuating mechanism of one of the two signalling arms on the car, and the centre port is a vent port. A recess in the valve connects all three ports when it is in its neutral position. Ports cut in the valve connect the desired seating port with the compressed air space when the valve is in either operating position.
