Abstract: This automotive steering wheel lock is made up of a rod and a cartridge connected with the rod. The cartridge consists of an upper half cartridge and a lower half cartridge that capture hold of the steering wheel between them and are locked with a lock cylinder and a lock base set separately in the two half cartridges when said half cartridges are closed together. To open the lock, a key is inserted and turned in the keyhole of the lock cylinder. The bottom of the rod can be blocked by the driver's seat or something inside the car or by a thief's body making it difficult to handle the steering wheel, even if the steering wheel should be turned around with the lock locked in an attempt to steal the car.

Abstract: A steering wheel locking mechanism comprises an elongated bar. One end of the bar is positioned adjacent the center of the steering wheel. An arcuate boot having the same radius of curvature as the curvature of the steering wheel and the same cross sectional curvature as the curvature of the cross section of the steering wheel is mounted over an arcuate segment of the periphery of the steering wheel. The concave surface of the boot embraces the outer periphery of the steering wheel. The steering wheel has at least one spoke connecting the steering wheel shaft at the center of the steering wheel with the periphery of the steering wheel. A portion of the elongated bar lies over the spoke. A chain is welded to the bar and is wrapped around the spoke and is attached to the chain lock with the concave surface of the boot embracing the outer surface of the steering wheel.

Abstract: The front half of the knob shell and the cylinder are removable from the rest of the lockset without special skill or tools so that cylinder may be replaced or rekeyed. A radial retainer pin in the cylinder assembly extends outward into the lockset shank to hold the cylinder in place. When key is turned counterclockwise, the retainer pin may be depressed inward into a radial recess in the cylinder plug so that cylinder and knob front can be removed from the lockset. A recess in the plug has a spring-biased cover and forces the retainer pin back outward when the pin is released.

Abstract: A vehicle anti-theft device attachable to a steering wheel. The device is in the form of a wheel-like member having an inner disposed bight defining a space for admitting a rim of the steering wheel, the open portion of the bight having at least one pair of opposed slots for admitting a free end of a lock bar which is lockable by a lock. The device extends the size of the steering wheel along the radial and tangential directions, thereby increasing the size of the steering wheel, which will encounter obstacles with respect to the vehicle structure and the occupant attempting to rotate the steering wheel. In one embodiment, the device includes an elongated bight member having two pairs of opposed slots which are traversed by a U-shaped saddle member passing through the slots and defining a locking space about the rim of the wheel. A lock is associated with the saddle member for maintaining the saddle member in an engaged position with the bight member.

Abstract: The accessory locking device including hingedly connected shells having confrontable flanges that have convexly curved outer surface portions, each flange having a notch therein. A keeper tube has a slot so that the keeper tube is longitudinally slidable over the convexly curved portions of said flanges. Secured to the keeper tube is an auxiliary cylindrical lock having a projectable and retractable bolt, said bolt being projectable through a hole in the keeper tube so as to provide obstructive interference with the notches in said flanges. In this way, the keeper tube cannot be slidably withdrawn from the flanges until the bolt is fully retracted from the notches.

Abstract: This invention provides a method and apparatus for preventing an ordinary door knob from being rotated, thus preventing the plunger-type bolt from disengaging from the striker plate and plunger pocket in the door jamb. The apparatus is attached to the shaft of the door knob on the deepest side of the door jamb. Once secured in place by the locking mechanism, enclosing all but the shaft of said door knob, its shape and design will prevent any effective rotation of the apparatus, or the door knob, due to its proximity to the door jamb nearest the door knob.

Abstract: A doorknob security apparatus (10) includes an upper housing (14) and a lower housing (16) which cooperate to form a cylindrical member. Hinge parts (24) and (26) are disposed on one edge of the halves and a locking member (20) is disposed on the other side to secure the two halves together. A cover (18) is mounted in annular grooves (28) and (30) on the periphery of the two halves (14) and (16). Semi-annular rings (32) and (38) are disposed on the interior of the housings (14) and (16) to form spaces (34) and (40) while receiving the gripping portion of the doorknob. An orifice is formed with the semi-annular rings to fit about the stem of the doorknob with a diameter less than gripping portion of the doorknob to prevent removal of the apparatus (10) from the doorknob. Reinforcing portions (44) and (46) increase the structural integrity of the semi-annular members (32) and (38).

Abstract: A lock mechanism for securing the cabinet of a security validator. A latch handle is maintained within a recess within a latch housing. The handle is pivotal about an axis and moves within an opening in the latch housing, transversing a slot within the housing. A lock cylinder has a plate connected thereto and adapted for positioning within the slot to engage and maintain the handle within the recess and slightly depressed therein. The handle is spring-biased to normally urge it from the recess. A freely rotatable disc is positioned before the lock cylinder to prevent unauthorized access thereto.

Abstract: A locking device for a manually movable wheeled storage rack is described, which storage rack is provided with a manually operated rotatable handwheel, and power transmission mechanism for transmitting the rotational power imparted to the rotatable handwheel to drive wheels, thus causing the storage rack to be moved. The locking device is movable forward and backward in the axial direction thereof by manual operation at the rotatable center section of the rotatable handwheel. This locking device is capable of restricting the action of the power transmission mechanism, rendering the transmission of the motive force impossible, thus making the storage rack incapable of motion. This device can subsequently be released, thus rendering the movable rack once again capable of motion.

Abstract: A device for theft-proving vehicles such as passenger cars, trucks and omnibusses which comprises two body halves (1, 2) being pivotionally connected at their one ends (9, 10) and having recesses (13 through 18) at their other ends (3, 4). A lock (25) is fixed in the one body half (1) and a lock counterpart (26) in the other body half (2). The device can be closed over a steering wheel, the recesses (13 through 18) encompassing the cross beam and the ring thereof. In this situation, the device allows only limited turning of the steering wheel, since it hits against seat or window of the car.
