ABSTRACT:
A system for locking either all or all but one of the drawers of a file cabinet. A bar rides in a groove at the interior of the shell of the cabinet. A plurality of drawer locks is engaged to the bar, each drawer lock including inclined and vertical surfaces at its rear edge. A rail having a key end is positioned at the side of each drawer so that the blunt end of the key faces the inclined surfaces of an associated drawer lock when all drawers are closed. The engagement of the blunt end with the opposed inclined surface of a lock raises the bar so that the blunt ends of the rail members associated with the remaining drawers abut and are locked by the vertical surfaces of the associated drawer locks. A block at the top of the bar abuts the cylinder of a cabinet lock when extended to prevent the vertical movement of the bar, locking all drawers.
