ABSTRACT:
A conductor rail and method for its production. The rail is constituted as a bimetallic, non-integral, unitary laminate assemblage of two formed, nesting dissimilar metal strips, for sliding engagement by an electrical collector shoe. The assemblage has a grooved track portion for receiving the shoe, and a suspension portion adapted to be clamped by suspender fittings. One of the metal strips is fully exterior to the other strip and is preferably constituted of steel, whereas the other metal strip is preferably copper, characterized by relatively higher electrical conductivity. The arrangement is such that the nested strips are in intimate, large-surface contact with each other. The rail thus enjoys the advantage of high strength and abrasion resistance, and improved electrical performance. The rail can be utilized in new equipment, or as a replacement for worn or damaged rail sections, essentially without modification of existing hanger or insulating hardware, or existing jacketing insulations.
