  • Glass lamp base
    Patent number: 5032759
    Abstract: A glass lamp base may be formed by thinning the glass base in the area behind the point where the side lead is welded to the exterior surface of the screw. Thinning the glass behind the weld area helps assure that the remaining glass is firmly positioned to the back of the screw in the area of the weld, and has not slumped away from the screw. Assuring the glass backing is present, increases the likelihood of a successful weld, and functional lamp.
