<p>A combination lock has a faceplate movable from a first position to a second position only when combination dials are set to an opening combination of the lock, the dials being movable with the faceplate portion from the first position to the second position and being rotatable relative to the faceplate. A spring biases the faceplate portion toward the first position. A manually shiftable member, also movable with the faceplate from the first position to the second position, is shiftable relative to the faceplate to hold the faceplate in the second position and, at the same time, to permit the dials to select a new opening combination of the lock. The faceplate constitutes a manual actuator that controls a latch.</p> |
