Abstract

268,932. Cooper, W. J. F. March 1, 1926. Illumination, changing advertisements by controlling. - A sign comprises a casing &c. fitted with a transparent or translucent screen bearing signs illuminated by an electric lamp 8 of high resistance and low current consumption. The lamp R is connected in series with a main lamp 11 of comparatively low resistance, which illuminates the sign when the lamp 8 is shunted by a switch 12. On opening the switch 12 to put both lamps in series, the lamp 8 only is illuminated. When the main lamp 11 is located in such a position as not to throw light on the sign, a second lamp of low resistance in series with the lamp 11 is placed in the sign casing.
