Abstract

1,150,826. Electric incandescent lamps. SYLVANIA ELECTRIC PRODUCTS Inc. 5 July, 1967 [5 July, 1966], No. 31039/67. Heading H1F. A lead-in wire 3 which is attached to a coiled filament 2 by fitting the end of the wire into the coil is provided with a portion 11 of reduced cross-section forming a shoulder 12 facing away from the end of the wire and at least one turn of the coil is deformed to engage in the portion so that the shoulder opposes withdrawal of the filament from the wire. The filament may be deformed by hot pressing between the anvil 13 and ram 14 of an arbor press.
