ABSTRACT:
A heavy duty industrial or agricultural hinge for pivotally interconnecting two members, the hinge including a rod adapted to extend through interleaved ears affixed to the members. In order to establish adequate lateral clearance at the hinge joint, each ear is formed with a half round-half rectangular configuration which serves to automatically space the bearing portion of the ear a proper distance away from the hinged member. An arcuate insert is fixed within the ear and coacts with the half round portion of the ear to form a generally cylindrical bearing portion for the hinge rod.
