Abstract: An electronic door lock is provided with a single control knob used for entering a predetermined combination through manipulation of the knob in a first arc of rotation, the code being entered by pushing the dial inwardly to bring a push pad into contact with individual ones of an arcuate array of electrical switches provided on a printed circuit board within the lock dead housing, the release of the door locking bolt being accomplished after entry of the predetermined code by further manipulation of the control knob through remaining portions of knob rotation which are unavailable until after entry of the predetermined code. A digitally operated code input pad assembly is also provided to enter such code and a second code to open a second lock mechanism associated with the door spring bolt giving two levels of security for the human passage door.

Abstract: A coin roll dispensing mechanism for use in dispensing coin rolls from a safe, the mechanism includes a coin roll dispenser for selectively distributing individual coin rolls, electrically operated solenoids to prevent operation of the dispenser and a first electrically operated combination entry device to disengage the solenoids. The safe door has a door handle, a plurality of bolts, a bolt works to manipulate the bolts, and electronic lock to restrict manipulation of the bolt works and a second electrically operated combination entry device to disengage the electronic lock. Upon entry of a first code sequence, the user can select a coin roll to be dispensed. To unlock the safe, a second code sequence is entered, which disables the electronic lock, allowing manual manipulation of the door handle.

Abstract: In an electronic digital safe lock including a slide plate pivotally connected by an articulated linkage to a bolt operating lever for retracting safe door locking bolts after digital input of the electronic lock combination, a lock override is provided which includes a dial operated mechanical combination lock having a linkage pivotally interconnecting the manual combination lock bolt with the electronic lock articulated linkage of the slide plate and bolt operating lever. When the electronic lock is locked, i.e., the slide plate is immovable, the manual combination lock can be manipulated to operate the aritculated linkage to operate the bolt operating lever independent of movement of the slide plate.
