Abstract

212,724. Railing, A. H., and Angold, A. E. Feb. 19, 1923. Dynamo lamps.-In a magneto hand lamp, the part of the case containing the generator is designed to lie within the palm of the hand, and the frame c and case b are stepped at b<5> to constitute a shallow part for the driving-mechanism and a deeper part for the generator. The neckportion b<6>, b<7> is formed with rounded corners to facilitate gripping by the thumb. In the construction shown, a rotating magnet is employed; the ring magnet f, f<1> surrounding the fixed armature f<2> is driven by a train of gearing e - - e' from a toothed quadrant a<1> secured to the operating-lever a.
