Hinge with interfitting locking means

A hinge comprising first and second leaves of substantially equal length, an unheaded hinge pin pivotally connecting the leaves along adjacent edges and being substantially equal in length to the leaves, the first leaf having two spaced aligned cylindrical bosses positioned at the opposite ends thereof and having aligned openings therethrough of the same diameter as the hinge pin, the second leaf having two spaced aligned cylindrical bosses positioned between the bosses of the first leaf and being of such length and position that their outer end surfaces are respectively spaced from the inner end surfaces of the bosses of the first leaf and having aligned openings therethrough which are of larger diameter than the diameter of the hinge pin, a headed bushing within each boss of the second leaf having its head within and filling the space between the bosses of the first and second leaves with which it is associated, each of said bushings having an opening therethrough of the same diameter as the hinge pin, a cylindrical retainer separate from the two leaves formed of a resilient material and positioned between the bosses of the second leaf and having an axial opening therethrough aligned with the openings through the bosses of the first leaf and those through the bushings and the diameter of which is such that the hinge pin is resiliently engaged by the material of the retainer and relative rotation between them is permitted, the hinge pin extending through the aligned openings in the bosses of the first leaf, the openings in the bushings in the bosses of the second leaf and the opening in the retainer.
