Abstract
A circular rotating member, having an outer peripheral surface, is rotatably mounted in a ring member. The rotating member includes an elongated central slot and four peripheral slots extending inwardly from the peripheral surface of the rotating member and spaced at 90 degrees from each other. The key of the combination lock extends into the central elongated slot, and a ball bearing is carried in each of the peripheral slots of the rotating member. The inner surface of the ring member is substantially identical to the outer peripheral surface of the rotating member but the inner surface of the ring member includes, additionally, two cut-outs. Thus, when the ring member is driven to rotate at a high speed by an automatic dialer, the ball bearing will be driven by centrifugal force into the cut-out whereby to prevent further rotation of the dial to thereby block the lock.
