  • Patent number: 5214944
    Abstract: An apparatus for attachment over a hub of a vehicle wheel to prevent its rotation and prevent the wheel from being removed from its axle. The apparatus has a generally triangular shaped shell having an upper and lower triangular plate spaced apart by a series of vertical pins. The apexes of the triangular plates have openings formed therein for receiving one end of a hooked rod. The other ends of the hooked rods extend through the shell and are held in place by the vertical pins and a locking screw-threaded nut-sleeve locking assembly. The hooked ends of the rods engage the circumference or tread of the tires and are held firmly in place by tightening the locking screw against the rods. A padlock secured to the assembled device through the sleeve of the locking device prevents tampering with the apparatus when in place on a vehicle wheel.
