Abstract
A trolley rail section is formed from a tubular housing that 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 opposed openings therethrough, with each pair of openings communicating with a different one of the slots. Disposed in each partition wall opening and straddling the adjoining conductor bar is a U-shape metal clip with inturned free front edges overlapping the front of the bar. Disposed in the clip behind the bar is a metal plate that is pressed against the bar by set screws threaded in the back of the clip. A rigid metal conductor connection extends loosely through an opening in the back of the clip and is rigidly secured to the plate and provided with an abutment spaced rearwardly from the clip. Compressed between this abutment and the clip is a coil spring for moving the plate rearwardly away from the adjoining bar if the screws are retracted.
