Abstract
564,493. Lamp caps. BRITISH THOMSON-HOUSTON CO., Ltd. April 6, 1943, No. 5474. Convention date, April 9, 1942. [Class 39 (ii)] [Also in Group XXXVI] A lamp having openings 16 in the envelope for the passage of stiff lead-in conductors 19, the openings being covered by cupshaped thimbles 20 sealed to the envelope as described in Specification 471,301, [Group XXXVI], has an insulating base 27 carrying contact prongs 28 that are secured to extensions or nipples 21 on the thimbles 20. In one form the base 27, Fig. 1, is attached by means of the arms 29 of the prongs 28 which pass through the base and are fixed thereto by bent-out lugs 32. The arms 29 are formed into eyelets 33 that fit over the nipples 21 and may be secured by solder 34. In a modification the base 37, Fig. 4, has apertures to fit over the nipples 21. so that the eyelets 33 secure the base directly to the nipples and tags 40 provide a second point of attachment for the prongs 28. Specifications 515,091, 526,924 and 557,598 are also referred to.
