Abstract

1,157,399. Electric battery lamps. UNION CARBIDE CORP. 30 April, 1968 [12 Jan., 1968], No. 20328/68. Heading F4R. [Also in Division H1] . A battery torch is detachably secured to a surface of magnetic material by a magnet assembly 44 which comprises a magnet 56 having polepieces 48 and a leaf spring 60 arranged so that the polepieces 48 are normally held in a retracted position within the torch by the spring 60 but on approach to a surface of magnetic material the magnetic force of attraction exceeds the spring force so that the magnet and polepieces move to a position in which the polepieces protrude through slots in the body of the torch and contact the surface to support the torch. The torch is detached by pulling it free from the surface and the polepieces are retracted by the spring 60. The torch is provided with a slide switch 34 and a compression spring 32 is located between the batteries 12 and a terminal 30 of the bulb holder 26. .
