Abstract

214,540. General Electric Co., Ltd., and Higgins, C. Sept. 10, 1923. Filaments; filaments, supports for.-In an incandescent lamp in which the filament consists of a number of parallel straight coils 2 in a common plane, for instance as used for projection purposes, the conducting supports 1 are joined above the filament by a refractory bridge 3 carrying the intermediate supports 4 and below the filament by one or more refractory bridges 5, 6 through which metal anchoring members 7 are freely guided so as to keep the filament sections taut with changes of temperature. The bridges may be of porcelain, magnesia or the like and the supports 4 may be made of refractory metal wires having one end passed through holes in the bridge prior to the formation of a few turns around the bridge. The lower ends of the anchors 7 may be flattened to prevent them from passing through the bridge 6 when the lamp is inverted. Specification 175,025 is referred to.
