Abstract

23,380. Atkinson, T. N., and Churchman, H. E. Oct. 22. Switches.-A switch for connecting the several filaments of the incandescent lamp shown in Fig. 3 singly or in parallel comprises an arm b rotatable about a central terminal n, and projecting through a slot in the cap. The slot has indentations corresponding to the switch contacts, each indicating a different candle-power. Current is supplied to the terminals m, o by springs l connected to the contacts d on the cap. Fig. 4 shows one way in which the filaments may be connected, the radial lines indicating the positions of the switch arm b and the numerals the corresponding candle-powers.
