Abstract

307,482. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Fisher, A. W., and Wells, W. B.). March 10, 1928, [Convention date]. Signal lamps.-A signal lamp is provided with a projection lens. the switch portion 3 of which projects a substantially parallel beam, whilst an outer integral portion 4 arranged outside of the parallel beam projects a divergent beam 17 to provide an auxiliary indication visible from positions closely adjacent the signal. A manual mirror H projects rearwardly-directed rays of light from an electric lamp bulb F through the central portion 3.
