ABSTRACT:
A lockable door hinge is described which is of the usual butt hinge type with a pair of pivoting butt plates. One of these plates contains a vertically slidable bolt which moves into and out of engagement with at least one projecting abutment flange on the other butt plate. By vertical positioning of the bolt, the door may swing freely or it may be limited in its swinging movement to a closed position or one or more partially open positions. The bolt may also be used to hold the door in an open position.
