Abstract

463,320. Electric couplings. SCANES, A. C. Oct. 2, 1935, No. 27167. [Class 38 (i)] [Also in Group XI] One or both filaments of a lamp are brought into use by rotation of the lamp in its holder, the filaments being connected respectively with stud and elongated contacts a, A respectively on the lamp cap. The contacts of each pair are close together so that the plunger contacts of the holder may engage both simultaneously. The bayonet pins are carried by strips c supported, for relative arcuate movement in the cap, by struck-out loops e. The stem supporting the filaments is of two diameters, the leads to the lower filament i<1> emerging through the shoulder m<1> thus formed at the support for the upper filament (not shown). These leads also traverse the exterior of the stem between the points p m.
