Abstract
388,064. Vehicle lamps. P. S. R. LAMP CO., Ltd., Carleton Works, and PARKIN, H., Carleton Villa, both in Liversedge, Yorkshire. Aug. 18, 1931, No. 23279. [Class 75 (iv).] Lantern screens.-In an anti-dazzle device for headlamps comprising a tubular opaque screen normally positioned in advance of the light bulb and adapted to be moved rearwardly to surround the bulb, the screen moves in an arcuate path so that in the normal out-of-action forward position it is coaxial with the axis of projection of the bulb and in the rear in-action position is inclined downwardly and forwardly. The screen, Fig. 1, is carried by arms 5 pivoted at 6 to a bracket 7 attached to the rear of the lamp reflector 2 and is normally held in the forward axial position by a spring 14. The passage of a current through a solenoid 10 carried by the bracket 7 causes a movement of a core 12, one end 13 of which abuts upon and actuates the upper end 8 of the arms 5 thus bringing the screen into the rearward inclined position. Resilient buffers 15 of rubber or other material are provided on the screen. A projection 16 on the core co-operates with a spring switch 17 so that at the end of the movement some of the coils of the solenoid are cut out, the remainder being sufficient to maintain the screen in the operative position. Alternatively all the coils may be cut out, in which case the screen is held in position with an oscillating motion as the circuit is made and broken by the spring switch. In a modification, Fig. 4, the solenoid is arranged horizontally and is provided with two cores 21 acting upon the end 8 of the arms 5 through bent levers 22. One of the levers is provided with an extension 24 co-operating with a resilient switch arm 26 adapted to contact with one of two arms 27, 28, thus including in the circuit the whole or part respectively of the solenoid windings.
