Abstract
A trolley rail is formed from a plurality of aligned tubular housings, each of which has a front side provided with laterally spaced slots extending lengthwise of the rail, and a partition wall extending across the inside of the housing and closing the inner sides of the slots, the side walls of which are provided with grooves receiving electrical conductor bars. The partition wall and the back of the housing have pairs of aligned openings therethrough, with each pair of openings connecting with a different one of the slots. Disposed in the partition wall openings and straddling the adjoining conductor bars are U-shape metal clips with inturned free front edges in front of the bars. The clips are provided with springs or screws pressing conductor bars therein against the inturned edges of the clips. The bars may either overlap in the clips or be disposed end-to-end to form a splice, or each clip may contain a single bar and a metal conductor strip pressed against the bar and extending out of the back of the rail to form an electrical tap to the bar.
