ABSTRACT:
A rod repair splice having a pair of trough shaped bodies each with a rod embracing arcuate flange at one end thereof. The bodies are diametrically mounted on the rod to be repaired with the respective arcuate flanges thereof disposed at longitudinally opposite ends of the splice. Each of the bodies is welded along their opposite longitudinal side edges to the peripheral surface of the rod sections. Each axial end portion of the bodies includes three distinct camming surfaces which slope from the inner surface of the body adjacent to the rod to be spliced to the outer surface of the body. The sloping surfaces thereby avoid shoulders which might cause hangup upon axial movement of the repaired rod by camming an axial interference in a radially outward direction out of axial contact with the splice.
