ABSTRACT:
A reversible mortise lock including a housing having a front plate and side walls, and a latch movable between an extended position in which it projects through the front plate, and a retracted position. Two spindle hubs, for cooperation with the spindles of inner and outer door knobs, are independently pivotable about a fixed axis, the latch moving from its extended to retracted position in response to pivotal movement of either spindle hub. An abutment member is pivotable between two extreme positions; in one extreme position it interferes with pivotal movement of one spindle hub, but not the other, so as to prevent that one hub from causing retracting movement of the latch; in the other extreme position, the abutment member does not interfere with movement of either spindle hub. The abutment member is exposed through an opening in the front plate so that it can be swung between its extreme positions by finger pressure. A pivot pin, upon which the abutment member is pivotally mounted, is removable through a hole in one of the housing side walls to free the abutment member for removal through the opening in the front plate. Upon removal of the abutment member, it can be reversed and reinserted into the housing and its pivot pin replaced. The abutment member will then, in one of its extreme positions, interfere with pivotal movement of the other of the two spindle hubs but not with the one which it previously interfered with.
