Abstract
577,757. Electric battery lamps. WARNE, J. March 3, 1944, No. 3967. [Class 39 (ii)] A wire helix A of conico-cylindrical profile is screwed on or into the end E of a torch case C to enable it to house a longer battery D. The battery if of small diameter is preferably inverted so that its base engages the lamp terminal and the conical end of the helix centres it and engages the carbon electrode at B. Alternatively the helix may be wholly cylindrical and its open-coiled end may be provided with a hooked, cranked or transverse portion or it may be solid.
