  • Patent number: 4333325
    Abstract: A steering shaft locking device has a locking rotor rotatably mounted in a housing which is key actuated. A movable piece is moved radially outwardly of the rotor when a key is inserted therein, but is free to move inwardly when no key is present. A cam on the end of the rotor moves a lock bar transversely of the rotor against the action of a first spring. A projection on the edge of the lock bar engages one end of a lock shaft for moving it in one rotational direction from a neutral position, at which it is held by a second spring which is weaker than the first spring, and the other end of the lock shaft has a shape such that when it is moved in the one rotational direction, it moves away from the movable piece, and when it is moved in the other direction by the movement of the lock shaft by the first spring, it moves the movable piece, and thus permits the lock bar to move past the one end of the lock shaft.

  • Patent number: 4333326
    Abstract: An improved vehicle lock immobilizes the shaft of a single foot pedal assembly of the vehicle is disclosed. The vehicle lock comprises a base which contacts the floor of the vehicle and fits between the floor and the shaft of the pedal. Two wall members extend upwardly from one end of the base and together with the base form a cradle for the shaft. A lock mechanism, e.g., a pad-lock, passes through one or more holes in each of the walls to thereby lock the shaft in the cradled position and render the pedal assembly and vehicle inoperative.

  • Patent number: 4331012
    Abstract: Lockable meter retention rings for securing electric meters in meter boxes comprise an inner ring of multiple arcuate parts wherein the inner ring has spaced-apart inwardly extending flanges for holding the electric meter in the meter box and a steel outer ring which fits over and engages with the inner ring wherein the outer ring keeps the inner ring assembled. The outer ring has a lock enclosure which, together with a portion of the inner ring, defines an opening for receiving and retaining a barrel lock, the barrel lock securing the rings together. Bayonet and screw type engagements between the inner and outer rings are disclosed, with the barrel lock preventing relative rotation of the rings necessary to disengage them. Another form of engagement has a flange of the outer ring received by the inner ring, with the barrel lock securing the outer ring to the inner ring diametrically opposite the flanged engagement.

  • Patent number: 4328688
    Abstract: An antitheft device is provided for use with a reversible type key. The device includes a plate movable in a slot extending transverse to the direction of a key-receiving slot. The key entering the slot moves the plate which, in turn, pivots a lever to latch with the lock to prevent the antitheft device from becoming operative as long as the key is in the key-receiving slot. The plate has a guiding surface which rides in a plane surface on the key as the key is inserted. The plane surface on the key moves the plate and lever to the desired position.

  • Patent number: 4322959
    Abstract: A locking means for a trunk in an automobile is disclosed which can be unlocked by the rotation of a key inserted in a key cylinder of the trunk and which comprises a first switch provided at a proper location in the room of the automobile to open and close a D.C. circuit including an actuator means for unlocking the locking means. A second switch which is usually closed is provided in said D.C. circuit in such a way as to be opened by the rotation of said key inserted in the key cylinder of the trunk in a direction contrary to that for unlocking the locking means, thereby it becomes possible for a proprietor of the automobile who stands outside the automobile near the trunk to actuate the second switch so as to prevent the opening of the trunk by any other person against the will of the proprietor.

  • Patent number: 4314157
    Abstract: A safety lock for securing a radiation source in a radiography exposure device is disclosed. The safety lock prevents the inadvertent extension of the radiation source from the exposure device. The exposure devices are used extensively in industry for nondestructive testing of metal materials for defect. Unnecessary exposure of the radiographer or operator occurs not infrequently due to operator's error in believing that the radiation source is secured in the exposure device when, in fact, it is not. The present invention solves this problem of unnecessary exposure by releasingly trapping the radiation source in the shield of the radiography exposure device each time the source is retracted therein so that it is not inadvertently extended therefrom without the operator resetting the safety lock, thereby releasing the radiation source. Further, the safety lock includes an indicator which indicates when the source is trapped in the exposure device and also when it is untrapped.

  • Patent number: 4309882
    Abstract: An antitheft device for a steering shaft of a motor vehicle has a latch which is movable between a latching and an unlatching position with respect to said steering shaft. A stop element in the form of a ball is provided in a radially extending opening in a stationary cylinder. The ball overhangs a projecting portion of the latch to prevent the projecting portion of the latch from moving past the ball. A rotating cylinder into which a key is inserted is rotatably mounted on the inside of the stationary cylinder and has a pair of circumferentially and longitudinally spaced detents into which the ball moves as the rotating cylinder moves past the radially extending opening. When the ball drops in the remote one of the detents, the projecting portion of the latch moves past the ball whereupon movement of the rotating cylinder moves the ball out of the detent to prevent the projecting portion of the latch from accidentally moving past the ball.

  • Patent number: 4307589
    Abstract: A lock comprises a cylindrical case with a turnable member rotatably mounted therein. A latch member is also rotatably mounted in the case. The latch member is rotatable in a first direction to lock the lock and in an opposite second direction to unlock the lock. A drive member is co-rotatably mounted in the case between and with the turnable member and the latch member. At least one magnetically attractable tumbler is movably mounted on the interior of the turnable member and has a portion which projects into engagement with a receiving cavity of the drive member when the lock is in an unlocked position. This permits the drive member to move axially away from the latch so that rotation of the drive member to rotate the latch to an unlocked position will release the latch.
