Abstract

10,071. British Thomson-Houston Co., [General Electric Co.]. April 30. Incandescent lamps.-Filaments are supported by radial arms mounted upon vertical springs which can bend transversely ; this allows the filaments to contract considerably without materially increasing their tension, and protects them from shock. The arms are of metal which does not alloy with the filament, and may be of copper or tantalum for tungsten filaments. The Figure shows a fourfilament lamp, in which pairs of supporting-arms 15, 16 are fused in glass beads 13 on coiled steel springs 11 mounted on a cross-bar on the central glass stem 3. The arms are set in the beads so that they do not touch each other or the supporting- springs.
