ABSTRACT:
A chain return support suitable for use in an en masse grain conveyor has a track with a pair of angle irons extending lengthwise in the interior of a trough and supported by horizontal cross members bridging two side walls of the trough. The angle irons have inwardly facing horizontal edge portions and vertical lower portions. A plastic slide is inserted between the angle irons and is engaged with the angular edge portions by way of grooves extending lengthwise on side surfaces of the plastic slide. Stops on the cross member contact the lower portions of the angle iron for proper positioning of the track. The plastic slide provides a low friction surface for supporting the chain return section.
