ABSTRACT:
A trolley conveyor comprising a hollow guide rail within which an endless conveyor chain is centrally supported by guide rollers. A plurality of spaced U-shaped hangers supported by said chain extend through a longitudinal opening in one side of the guide rail spaced above the bottom of the rail. The lower side of the guide rail below the opening is inclined outwardly and serves to contain foreign matter present within the guide rail as well as to catch matter falling from above. The hangers each include a projection adjacent the longitudinal opening which serves to prevent the splashing of foreign matter from the interior of the guide rail out through the opening.
