Abstract: In the single-nut wheel assembly (1) the mutual contact surfaces (13, 23) between the nut (4) and the hub (3) do not rotate against each other during rotation of the nut (4). For this purpose, the nut (4) (or as an alternative the rim (3)) is provided in two bodies (15, 16) free to rotate mutually thanks to the interposition of antifriction means (17). The force necessary for tightening and loosening the nut is thus reduced.

Abstract: A Simulated Custom Wheel suitable for vehicles having elongated studs, that can be removed and inserted without removing the wheel from the axle or requiring the insertion of a ring or plate between the lug nuts and wheel of the vehicle. The decorative wheel cover having a central cut out to clear the lug bolts, is placed against the wheel but not attached. A retainer ring having sufficient openings to clear the number of lugs but not the lug nuts themselves is placed over the wheel lugs and against the lug nuts. The retainer ring and the wheel cover are connected together to form a unitary structure. At least three new nuts are placed on selected wheel lugs extending through the openings on the retainer ring and tightened. A center wheel cover having simulated lugs and lug nuts to match the wheel is placed over the retainer ring and attached to the ring to form a complete wheel cover without the necessity of removing the lug nuts holding the wheel to the vehicle.

Abstract: A cargo container lifting spreader compensating mechanism for facilitating engagement by the spreader with cargo containers having out-of-plane twistlock engagement receptacles, the invention comprising cross-members for carrying the twistlock lug members secured at the ends of the spreaders with rotatable connections whereby they are partially rotatable in a vertical plane perpendicular to the longitudinal axis of the spreader with a restrictor means to limit said rotation.
