Abstract
309,678. Winter, C. J. Feo. 21, 1928. Prisms, rotating; illumination, changing advertisements by controlling. - In signs having an inclined mirror whereby light is reflected either before or after passing through a stencil, a number of differently coloured mirrors are mounted on the sides of a prism which is rotated step-by-step or continuously so as to bring each mirror in turn into the inclined position. Fig. 1 shows an inclined stencil 1 illuminated in sequence by mirrors 5 on a hand-rotated polygonal carrier 3 registered by a pawl 6. The mirrors may be of silvered glass, tinsel paper, foil, sheet metal, &c. and each may be uniformly coloured or have bands &c. of different colour. The sign may be double-sided, and Fig. 3 shows such a sign having two carriers 3 connected together by a belt 11. Fig. 4 shows stencils 1 illuminated by the mirrors on a power-driven carrier 3. An elongated lamp may be fitted along the upper front edge of the casing for use at night.
