Abstract

147,831. Gross, F. Feb. 18, 1919, [Convention date]. Making lamps; leading-in wires; filaments, supports for.-In sealing leading-in wires into lamps, and particularly miniature lamps, the lamp is supported with its neck b upwards and the leads c are supported clear of the neck by a frame f. The wires c may be sealed between the neck and an exhaust tube g, and the joint flattened by tongs; or the neck may be squeezed so as to enclose the wires and leave a small central passage to which an exhaust tube is afterwards fused. The heating arrangements may consist of reciprocating burners mounted on at least two sides of the lamp; they may be swung aside after the operation operating a by-pass cock. The leading-in wires c support the filament and are secured in a glass block e.
