Abstract

The lock comprises a standard threaded mortise cylinder which includes a rotatable cam protruding from the surface opposite to the key receiving end of the cylinder. This cam is movable through an arc in response to the tuning of a key inserted into the cylinder so the cam will wipe across a bolt operating pin to actuate a bolt between an extended position and a withdrawn position. The lock also includes set screws, inaccessible from either side of a door in which the lock is installed, which prevent rotation of the cylinders. The cylinders hold cylinder collars in place to prevent access to the bolt from the side.
