Abstract
Abstract In a hinge lock, a first hinge leaf and a second hinge leaf which are pivotally interconnected to open about a vertical hinge pin. The first and second hinge leaves are generally T-shaped in cross-sectional configuration, each having a leaf portion interfitting between the edge of the door and the jamb and a locking plate portion extending respectively across the face of the door and the jamb. Extensions of the leaf portions project inwardly beyond the locking plates to form the pivotal pin connection. The respective inward surfaces of the first and second locking plates are each provided with a pair of keepers which coact with an opening provided in the extensions to receive a locking arm in sliding horizontal alignment therein. When the locking arm slides completely through the keepers and the extension opening, the arm serves to prevent opening of the door by preventing relative pivotal movement of the first and second hinge leaves. When the locking arm is horizontally urged out of the opening, the first and second hinge leaves are then free to swing about the hinge pin to permit povital opening of the door.

Claim 1
Independent Claim
357 words
In a hinge lock suitable for pivotally carrying a door within a frame from an open position to a closed and locked position, wherein one edge of the door abuts the jamb of the frame when in the closed position and wherein the door has an interior surface, the combination of, A. a fixed leaf affixed to the said jamb, 1. said fixed leaf terminating interiorly in a fixed locking plate, a. said fixed locking plate interiorly affixing to the said jamb, b. said locking plate extending at substantially right angles to the plate of the said fixed leaf; B. a movable leaf affixed to the said edge of the door and operating in cooperation with the fixed leaf, 1. said movable leaf terminating interiorly in a movable locking plate, a. said movable locking plate affixing to the interior surface of the door, b. said movable locking plate positioning at substantially right angles to the plane of the movable leaf; c. socket means extending interiorly from the said fixed and movable leaves, 1. said socket means including a fixed leaf extension extending interiorly from the fixed leaf and a movable leaf extension extending interiorly from the movable leaf, 2. said fixed and movable leaf extensions terminating interiorly in a pin socket, 3. said socket means including a hinge pin positioned within the pin socket to permit relative pivotal movement of the door with respect to the frame, 4. said fixed leaf extention and movable leaf extension each being provided with a locking arm receiving opening therethrough, a. said locking arm receiving openings being in horizontal alignment; D. slide channel means interiorly associated with the said fixed locking plate and the said movable locking arm receiving openings for hinge locking purposes; and E. a locking arm slidable within the said slide channel means and locking arm receiving openings from an open position to a locked position, 1. said locking arm permitting pivotal movement of the movable leaf relative to the fixed leaf when in the open position, and 2. said locking arm preventing relative movement between the fixed leaf and movable leaf when in the said closed position.
