Abstract

321,032. Grote, E. R. Oct. 1, 1928. Filaments, supports for.-In lamps of the kind wherein a continuous length of metal filament d extends axially of an elongated tubular envelope and is supported at intervals throughout its length by loose engagement in pigtails f mounted on a rod g, the filament is positively connected to one or more supports i at intervals in its length so as to limit the size of loosely supported lengths of filament subjected to stretching action when the lamp is used in a vertical position.
