Abstract

412,608. Signal lamps. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and SIMPSON, L. M., Lyndene, Kensington Avenue, Thorner, near Leeds. Dec. 30, 1932, No. 36925. [Class 75 (iv).] In road-traffic control signal casings, daylight from a top window 50 or light from a lamp 53 is reflected by mirrors 51, 52 on to one or other of the mirrors R, A, G co-operating with red, amber and green lenses respectively, the mirror R being fixed and the mirrors A, G movable. The cam-operated linkage for moving simultaneously the corresponding mirrors for a two-aspect casing is indicated at the bottom left-hand corner of the Figure. A modification is described wherein both red and amber lenses may be illuminated simultaneously.
