Electromechanical combination lock construction

Abstract

Abstract AN ELECTROMECHANICAL COMBINATION LOCK CONSTRUCTION FORMED OF A PLURALITY OF DIAL ASSEMBLIES HAVING AN EXTERIOR, MANUALLY ROTATABLE DIAL AND A SHAFT FIXED THERETO CARRYING A FIRST WHEEL OF INSULATING MATERIAL WHICH HAS A RADIAL ELECTRICAL CONTACT FORMATION AT A PARTICULAR ANGULAR POSITION THEREON, AND ANOTEHR WHEEL MEMBER OF INSULATING MATERIAL WHICH IS MOVABLE BETWEEN FORWARD AND REARWARD POSITIONS AXIALLY OF THE SHAFT AND CARRIES A SPRING CONTACT MEMBER TO ENGAGE THE CONFORNTING FACE OF THE FIRST MEMTIONED WHEEL AND CLOSE AN ELECTRICAL CIRCUIT WITH THE CONTACT FORMATION ON THE FIRST MENTIONED WHEEL AT A PARTICULAR ANGULAR POSITION OF THE DIAL. AN EXPOSED LEVER, AND A CAM OPERATED THEREBY, CONTROL CERTAIN LIMIT SWITCHES AND ACTIVATE A DEVICE TO MECHANICALLY COUPLE THE REAR WHEELS WITH THE FRONT WHEELS FOR COORDINATE ROTATION WHEN THE LOCK IS IN UNLOCKED CONDITION AND TO SHIFT THE REAR WHEELS TO A DECOUPLED RELATION TO THE FRONT WHEELS WHEN THE LOCK IS MOVED TO LOCKED CONDITION. THE LEVER AND CAM ALSO CONTROL RETRACTING AND PROJECTING MOVEMENT OF A BOLT WHEN THE LATTER IS RELEASED BY ESTABLISHING AN ELECTRICAL CIRCUIT UPON DIALING OF THE PROPER COMBINATION.
