Abstract
423,224. Vehicle &c. lamps. NEALE, R. W., 68, Graham Street, Birmingham. July 11, 1934, No. 20301. [Classes 39 (ii), 75 (iii), and 75 (iv)] Mounting electric lamps in lanterns antivibration devices; electric-lamp holders.-In a vehicle or like lamp in which the socket 12 of an electric lamp bulb 13 is slidable axially within a sleeve 10, 14 on a reflector 6 and is adjusted for focusing purposes by rotation of a nut 18 or like axial screw device projecting through a hole 21 in the back of the lamp casing 1 from the interior thereof, the screw device forming part of a focusing arrangement which, with the reflector, forms a unit detachably mounted inside the casing by means of a bezel ring 2 carrying a front glass 3, the nut 18 is centrally applied to a bracket 16 which is rigidly fixed upon the rear end of the socket 12 and is coupled to the reflector by pins 22 which are surrounded by coiled compression springs 25 and which secure the combined bracket and socket to the reflector both axially and against rotation. The nut 18 engages a screw-threaded peg 17 on the bracket and the pins 22 pass freely through holes 23 in the bracket and engage screwthreaded holes 24 in a circumferential flange 11 welded to the sleeve 10, the springs 25 forming an anti-vibration device. The bulb 13 has a single contact engaged by a spring-pressed plunger 27 which is connected to one of the leads of the wiring 30 and which is slidable within a conductive socket 28 arranged within an insulating plug 15 rigidly fitted into the rear of the socket 12.
