ABSTRACT:
A non-precious metal drain bushing for use in the start-up of a glass melting furnace. Relatively thin, wide terminal ears extend outwardly and downwardly from the ends of the bushing and are supported against bending stresses by a rigid band or strip which contacts the outer surface of the ears and extends along the bottom wall of the bushing toward the other end for a substantial distance. In addition to the physical reinforcement it provides, the strip also acts to electrically widen the terminal ears.
