The center knuckle of the one leaf fits between the two end knuckles of the other leaf and is maintained in alignment with them by top and bottom hinge pins, the former extending from the top knuckle into the center knuckle and the latter from the bottom knuckle into the center knuckle. Whereas the bottom pin is attached to the center knuckle, the top pin is attached to the top knuckle, but its angular position is easily changed. Each pin has a threaded portion that is located within the center knuckle, and the end convolutions on a coil-type torsion spring are threaded over these threaded portions to secure the spring to the hinge pins. Each hinge pin also has a shank which extends from its threaded portion through the interior of the spring where the ends of the two shanks abut.

Abstract: The swing control hinge disclosed is intended to control the rotational speed of a door that is tending to accelerate toward the strike as a result of spring loaded hinges. The hinge is intended to prevent slamming of the door while allowing enough speed to insure latching. The swing control hinge is housed in a hinge body that may be used as a third hinge. The hinge pin is made up of two cams that have cam parts on them which dissipate energy from conventional spring loaded hinges having helical spring or a block of rubber during the opening cycle of the door and the torsional force from the spring loaded hinges is dissipated in checking the door as it closes to keep the door from slamming.
