TROLLEY ELECTRICAL COLLECTOR Abstract of The Disclosure An elongated metal trolley shoe has a groove in one side extending from end to end for receiving a trolley wire, with the opposite side of the shoe provided with threaded holes having their inner ends spaced from the groove. Screws in the holes for attaching the shoe to a support are made of a material that is at least as soft as the shoe, so that if the portion of the shoe originally separating its groove from the inner ends of the screws is worn away by a trolley wire, further wear of the shoe will occur in the same direction because the screws will wear at the same rate instead of forcing the wire to wear into the side of the groove.
