A base for three-way lamps in which it is easier to feed lead wires through and a method of making such bases.

Three-way lamp bases and method for making them

A tool for making bases for three-way lamps in which it is easier to feed lead wires through because the tool has a first projection in the middle of its base which projection has a round cross-section of a given diameter in the plane perpendicular to the tool's longitudinal axis and a second projection having a cross-section in the forementioned plane having a longer circumferential dimension than a radial one and in which the circumferential dimension is at least as large as the diameter of the first projection in the forementioned plane.
