Abstract: 451,743. Vehicle &c. lamps. MORGAN, A., 79, Herzbergstrasse, Lichtenberg, Berlin. Nov. 13, 1935, No. 31452. [Classes 75 (iii) and 75 (iv)] In a vehicle lamp or like light projector adapted to project a non-dazzling beam of light, a part of the usual concave rear reflector is replaced by a non-reflecting surface, and an auxiliary reflector of paraboloidal shape facing the remaining part of the rear reflector is so disposed that the lamp filament is substantially at its focus. A part of the rear reflector may be made matt and of a dark colour, or it may be screened by a flat or curved partition having a non-reflecting surface facing the remaining part of the rear reflector. The part of the rear reflector divided off by the partition may be completelyomitted, or it may accommodate a horn, a small parking light, or a subsidiary bulb and reflector which projects a strongly concentrated parallel beam of light. The subsidiary reflector may itself constitute a part of the partition, or the latter may be formed integrally with the rear reflector. In addition to controlling the different lights by hand switches, the subsidiary projector may be controlled automatically by the steering gear. For this purpose a cam is fitted to the steering spindle and a pair of contact springs are mounted on the steering column so that the circuit through the subsidiary projector is completed only when the vehicle is steered straight ahead. The main lampholder may be axially slidable within a pivotally mounted sleeve whereby the anti-dazzle beam may be concentrated substantially horizontally or scattered downwardly for use in fog. In the form shown in Fig. 1, the lamp comprises a bulb 2 at the common focus of a main paraboloidal reflector 1 and an auxiliary paraboloidal reflector 5, the latter being riveted to a horizontal diametrical partition 3 having a non-reflecting upper surface.
