Abstract
A reversible mortise lock comprising a casing, a latch bolt and a pair of spindle hubs disposed within the casing. Each spindle hub is independently pivotable about a fixed axis and has a slot. The latch bolt moves from an extended position to a retracted position in response to pivotal movement of either spindle hub. The latch bolt is rotable to a first orientation and to a second orientation. The reversible mortise lock further comprises an interfering member disposed within and accessible from outside the casing. The interfering member has a portion thereof sized for insertion into the spindle hub slots. The interfering member is pivotable to a first position corresponding to the first orientation of the latch bolt that allows only one of the hubs to pivot and to a second position corresponding to the second orientation of the latch bolt that allows only the other hub to pivot. The interfering member is pivotable from outside the casing without disassembling the reversible mortise lock.
