Abstract
106,025. Gulston, H. S. July 12, 1916. Battery lamps.-A movable hood, which, when depressed so as to cover the lamp-bulb F, opens a switch in the lamp circuit, consists of a hinged cover plate E and sector-shaped side pieces E<2>, E', preferably bent so as to work stiffly in slots A<4> in the casing. Lugs limit the outward motion of the side-pieces, and dents E<4> retain the cover in closed position. In the path of one side piece E<3> is a contact spring D attached to the casing and resting, when released, on a strip C. This is attached to an insulating strip C' riveted to supports C<2> on the casing, and engages one battery terminal B. The other battery terminal is in contact with one bulb terminal. According to the Provisional Specification, there is provided a hinged clip for attaching the lamp to a belt or button.
