  • Electric lamp base and method of assembly
    Patent number: 4029387
    Abstract: A base assembly and method for electric incandescent lamps in which a preformed base insulator and contact eyelet are assembled with a conventional base shell by threading the insulator and contact eyelet as a subassembly into the shell. Provision is made for retaining the insulator and the metallic shell against unthreading rotation either by a direct binding of portions of the insulator and the shell or by serrating the inner edge of an in-turned flange on the shell in a manner to allow threading rotation of the insulator and shell but to prevent unthreading rotation of these parts.
