Abstract

1,101,389. Electric torches. STANDARD TELEPHONES & CABLES Ltd. 6 Jan., 1967, No. 841/67. Heading F4R. An electric battery lamp has a constant non-circular cross-section with at least one external metal strip along its length forming part of the electric circuit. The casing 1 may be elliptical with flattened areas at each end of the major axis on which are metal strips 2, 3, the strip 2 being interrupted with the interposition of a sliding switch 4, which can make contact with a strip 17 connected to the bulb holder. The base contact of the bulb is connected to the battery by a spring 19. The rear of the casing is closed by a plate carrying a spring contacting the battery, and anchored by a pin the ends of which pass through slots in the end of the casing, the plate being then turned to secure it in position, the pin then contacting the strip 2. The front of the casing is closed by a dome 21 of diffusing material sliding in the end of the casing and carrying a reflector 6 silvered on both sides, so that the light is diffused laterally when the dome is extended. A suspension ring may be provided on the rear closure plate.
