Abstract
A butt hinge has a pair of tapered leaves connected together by a removable pivot pin, an outer leaf having tubular portions at each end thereof for reception of the pivot pin, and having a central cut out area for reception of an inner leaf having an inner tubular portion for the pivot pin. Locating ribs are provided on opposite sides of the tubular portions, and together with central locating notches they facilitate the location and installation of the hinge on a door and jamb. The tapered over-lapping of the leaves avoids the need to provide rebates to receive the hinge, or the need to trim or bevel the edge of the door to prevent binding when the door is closed.
