ABSTRACT:
A double-enveloped electric lamp having a self-mounting frame-assembly for supporting a light-source capsule within the outer envelope, such frame-assembly being mounted by means of elastic and frictional forces other than glass-to-glass or glass-to-metal seals. In one embodiment of the invention, the frame-assembly is mounted on the neck of the outer envelope by means of a clamp on each leg of the frame-assembly; each clamp grasps the brim of the neck within a formed groove. Locking means may be obtained by mounting the lamp base over the grooves; barbed prongs on each clamp bite into the shell of the base and lock together the component parts of the lamp. In a second embodiment, a wire frame-assembly having two preformed legs with barbed prongs is mounted on the neck of the outer envelope by fitting each preformed leg into a matching groove formed in the threaded neck of the outer envelope. Locking means may be obtained when the lamp base is screwed over these grooves; the barbed prongs bite into the shell of the base and lock together the component parts of the lamp. Double-enveloped lamps having self-mounting frame-assemblies may be constructed more simply and economically than possible under the existing art.
