Abstract

310,547. Ruzicka, E. April 27, 1928, [Convention date]. Void [Published under Sect. 91 of the, Acts], Vehicde and like lamps; tell-tale devices.-In a vehicle or like lamp a source of light a is surrounded by a front lens c, lateral lenses d, d<1>, and reflectors e, e<1> so arranged as to project forwardly a substantially flat-torpped beam of light. The source of light may comprise an electric lamp bulb having its rear wall made reflecting and provided with a substantially horizontal filament b. The lenses may be secured to an annular collar, and the reflectors may be curved outwardly to increase the lateral spread of the projected beam of light, or replaced by prisms or the like. Specification 180,805 is referred to.
