Abstract
A collector shoe assembly for transmitting current from an electrified rail to a mobile unit such as a trolley, crane, conveyor, or the like. In a preferred embodiment the electrical collector comprises an electrically conductive shoe for slidably engaging an electrified rail, and a bracket assembly to support and guide the shoe along the rail. The bracket assembly comprises a parallel pair of pivotally supported brackets with a transversely extending support and pivot pin extending between the outer ends. Supported on the pin between the brackets is the shoe which includes a U-shape top channel adapted to receive the pin. The pin is loosely captured within the channel by a pair of readily removable bolt and washer assemblies which are threadedly secured into the top of the shoe. Such construction allows the ready replacement of the shoe and also enables the shoe to adjust vertically and pivot both forwardly and rearwardly relative to the bracket assembly, permitting the shoe to adapt to the various contours of the rail and remain in continuous sliding engagement therewith.
