Abstract

269,410. Wawra, O. Aug. 3, 1926, [Convention date]. Chromatropes. - An electric advertising device for shop windows &c. comprises a chromatrope 1 having a fixed disc 3 and a rotatable disc 5 illuminated by a rearwardly placed lamp 7. The disc 5, Fig. 5, has a serrated edge engaged by a flanged pawl 13 mounted on the armature 10 of an electromagnetic interrupter 9 connected to a variable resistance 8 in the circuit of the lamp 7. The vibrating pawl rotates the disc. Both discs may rotate, a double pawl being then used.
