A hinge comprises a stationary base for mounting directly to a furniture wall and formed with a central opening, a central insert having a smaller width than the central opening, and fitted therein at the bottom of the base, each of the transverse edges of the central opening having an inwardly directed projection formed with a downwardly facing groove, each of the transverse edges of the insert having a projection engaged with the groove along one transverse edge of the opening, and an L-shaped arm having a bifurcated portion received in a pair of grooves along the longitudinal edges of the base opening, and formed with teeth engaged in the teeth formed in the longitudinal grooves of the base. A pair of screws extend through a slot defined by the bifurcated portion of the arm, and are threadedly connected with the insert, whereby the L-shaped arm is secured to the stationary base movably in four directions for fine positional adjustment relative to the base.

Hinge

A hinge comprises an L-shaped stationary flap having a pair of legs each having a rounded, tubular end, an L-shaped rotatable flap having a leg formed with a rounded, tubular end aligned with the tubular ends of the stationary flap, and disposed between the legs of the stationary flap, and a hinge pin extending through the tubular ends of the flaps, and about which the rotatable flap is rotatable. A pair of oppositely directed cam shafts project from the opposite extremities of the tubular end of the rotatable flap and are each received in a recess formed in each leg of the stationary flap. Each cam shaft has a flat surface, and each recess of the stationary flap accommodates a cam rest and a spring urging the cam rest outwardly to maintain it in intimate contact with the flat surface of the cam shaft, whereby the door to which the hinge is attached is closed automatically, and kept in its closed position.

Self closing hinge

Combined door check and hook

A hinge having a hinge member mounted in an auxiliary hinge member made of a plastic, die casting or metal material in an overlapped relation thereto, with a decorative design provided on an exposed portion of the auxiliary hinge member.

An automatic door closing device includes a bell crank lever pivotablly mounted on the door which cooperates with a hook-shaped cam plate mounted on the door frame. A spring biased dash pot controls movement of the bell crank lever when the door is opened and closed, assuring that the door will close slowly but positively without slamming. Means is provided on the frame of the device to assure proper positioning of the bell crank lever with respect to the top edge of the door and the hook-shaped cam plate.
