ABSTRACT:
A locking hinge assembly includes two butt plates or hinge leaves each having a plurality of interlocking knuckles with an axially shiftable hinge pin mating with the knuckles. A locking mechanism carried by the top of the hinge pin includes pressure and sprocket plates, with one plate keyed to the hinge pin and spring devices adjustably compressible to apply varying degrees of biasing force against the movement of one hinge leaf relative the other hinge leaf. This is accomplished due to the juncture of one hinge leaf to the sprocket plate while the keyed pressure plate is fixed relative the other hinge plate.
