A mortise lock for mounting in a door. The lock includes a bolt movable along a first axis between a first, extended position and a second, retracted position. The bolt has an end which, when the bolt is in its first, extended position and when the door is moved to a closed position, engages a strike which urges the bolt toward its second, retracted position. Also included are means for biasing the bolt to its first, extended position. The lock further includes a driven member which is mounted for rotation about a second axis. The second axis is generally perpendicular to the first axis. As the driven member is made to rotate about the second axis, it engages the bolt and urges it, overcoming the bias, to its second position. A drive member is mounted for rotation about a third axis, generally parallel to the second axis. The drive member rotates between a neutral position in which a tooth extending from the drive member does not engage the driven member nor initiate rotation of the driven member, and a rotated position in which the tooth engages the driven member to move it into engagement with the bolt and urge the bolt to its second position.
