Abstract
A hinge pin and bushing assembly is provided for machine insertion into a barrel of a hinge leaf. The assembly is preferably molded in one piece from a resilient self-lubricating plastic and includes a bushing having a concentric bore, a hinge pin having an end connected to the bushing concentrically with the bore by thin webs. The other end of the hinge pin is attached concentrically to a cylindrical plug. The bushing portions of a pair of assemblies are inserted into opposite ends of the leaf barrel and compressive force is applied to the outer ends of the plugs thereby breaking the webs and inserting the hinge pins into the bushing bores.
