ABSTRACT:
An spring hinge construction comprising a pair of hinge leaves having hollow knuckle portions axially aligned to form a hinge barrel containing a torsion spring. A pintle in each end of the barrel operatively engages an adjacent end of the spring to fix it against relative rotation. One pintle is fixed, through a leaf knuckle, to one hinge leaf, and the other pintle is rotationally adjustable to set a desired torsion on the spring, after which it is fixed against counter-rotation by means of a loose pin which is inserted through an elongate slot in a knuckle of the other leaf and into a selected radial passageway opening in the pintle which aligns with the end of the slot. An anti-friction bushing and thrust washer carried by the adjustable pintle and located between opposed surfaces of adjacent knuckles, respectively, cooperate to provide positive securement of the adjustable pintle in the hinge barrel while permitting its free rotation therein, and corresponding free smooth relative movement of the hinge knuckles during use of the hinge.
