Abstract
518,204. Discharge lamps. GENERAL ELECTRIC CO., LTD., TIMMINS, J. H., and WOODWARD, R.A. Sept. 23, 1938, No. 27767. [Class 39 (i)] A lamp having an inner tubular envelope and an outer tubular jacket has a pair of members, one at each end of the envelope, having elastic parts, for example, projections, bearing against the inside of the jacket and pressed against the envelope by two or more rods or wires tensioned between them. In the form shown, the members 3, 3<1> have springy projections 5, 5<1> bearing on the jacket 2 and held against the envelope by two tensioned rods 6, 7. The rods are electrically connected together througt the members 3, 3<1> and tc the extreme electrode 14 by a lead 13, and they are welded to supports 10, 1] carried by the pinch 12 In an alternative form, the members 3, 3<1> are re placed by 4-armed wire members. The invention is particularly applicable to high-pressure metal vapour lamps.
