Methods and apparatus for automatically transferring electrical power

An electric clutch system for a mortise-type security lock is provided. The clutch system includes one or more magnets disposed in one hub of a mortise-type lock. The magnet is recessed and disposed below the interior surface of the hub that engages the opposing hub of the mortise-type lock. The opposing hub includes one or more spring-biased armatures. Upon the application of current to the magnet, the armature is drawn toward the magnet resulting in a coupling-type connection between the two hubs so that rotation of the exterior handle will open the door.

Electromagnetic clutch for electronic locks

A cylindrical barrel type lock wherein rotation of the barrel is prevented by one or more armatures which are actuated by an electromagnet. Energization of the electromagnet causes the armatures to be withdrawn from engagement with the barrel, thereby permitting its rotation to open the lock.
