ABSTRACT:
An overhead metal trolley rail has a head for supporting it, separated by a vertical web from a foot that projects from opposite sides of the web and has flat upper contact surfaces. Slidable along the rail is a trolley shoe formed from a block of electrical conducting material, the upper portion of which has a longitudinal trough in it receiving the foot of the rail. The lower portion of the trough is spaced from the rail, but the upper portion of the trough has longitudinal flanges projecting inwardly toward each other above the foot of the rail. The flanges have flat lower contact surfaces engaging flat against the flat contact surfaces of the rail and supporting the shoe, from which a power take-off wire extends.
