Abstract
An improved articulated link construction used in a conveyor belt tracking mechanism. The conveyor includes a frame having a pair of spaced parallel side rails that support a bed plate and an endless conveyor belt is supported on the bed plate. A spindle assembly includes a pair of side members that are mounted for sliding movement with respect to the side rails and a spindle is journaled between the side members. A plate-like link extends transversely of the spindle assembly and the ends of the link are pivoted to the side members. Each pivotal connection includes a vertical bolt that extends through an opening in the respective side member and a bushing is threaded on the bolt and is received within an oversized opening in the link. A spring washer is interposed between the head of the bushing and the link, and maintains the link in snug contact with the side rails yet permits pivotal movement of the link relative to the side members to enable the side members to be moved relative to each other to track the belt.
