Abstract: An emergency gate release for a lattice type gate having a lock on the gate for locking the gate to a static structure. The gate release includes a lock release mechanism on one side of the gate for unlocking the gate and a rotatable release knob connected to the lock release mechanism for actuating the lock release mechanism to unlock the gate without a key. The release knob is located on one side of the gate at a location remote from the lock and inaccessible from the other side of the gate.

Abstract: An adjustable depth gauge assembly for a key cutting device includes a rotatable gauge or cam member carried by a vertically and transversely movable key blank support that sequentially positions a key blank in selected cutting relationship to a cutting punch or die. The gauge or cam member includes a continuous uninterrupted cam surface which is sequentially engageable with a finger or pin disposed in the path of movement of the gauge member to selectively limit vertical movement of the key blank support. The gauge assembly also includes an indicator arm for rotating the gauge member to a desired position so that the depth of cuts in a key blank may be varied in accordance with a pre-established code pattern.
