Abstract:
A wedge lock wheel assembly for mounting a tire rim in which the assembly includes a hub rigidly attached to the rim having a chamber with a centerline substantially perpendicular to the disk, a plurality of stops and a plurality of pairs of paired ramps with a known hardness having complex angles relative to the disks, a plurality of sets of paired wedges positioned within the chamber capable of relative motion therebetween and having an aperture passing through each of said pairs, a generally flat and bottom surface, a slope top surface and a hardness greater than the hardness of the ramps, a plurality of restraining members for limiting the motion between sets of said wedge pairs, an axle having horizontal contact surfaces with a hardness greater than the hardness of the wedges and a plurality of connecting elements passing through said wedge apertures for establishing contact between said ramps and said slope surfaces and between said bottom surfaces and said contact surfaces.
Abstract:
A mounting construction for a wheel to an axle wherein a hub assembly on the wheel includes wedge members arranged for axial separation by a differential bolt to thereby effect a radial gripping of the wedge members with the axle. The wheel is thus securely locked to the axle and yet may be conveniently removed even after extended periods of time when the wedges are in locked position.

1,221,315. Releasing wheels from axles. INTERNATIONAL HARVESTER CO. 10 April, 1968 [20 April, 1967], No. 17221/68. Heading B7C. A method of releasing a wheel 11, see Fig. 3, from an axle 16 to which it is secured by wedgelike members 27, 31 comprises rotating a shaft 21, see Fig. 9, having an unthreaded portion between shoulder 25 and collar 30 and a threaded portion in a direction so as to cause the members to separate and to an extent to unwedge only one of the members, seating implements 45 having end flanges 46 on the members, and further rotating the shaft so that the flanges first limit movement of the unwedged member by engaging complementary flanges on the unwedged member and on the wheel housing and then cause the wedged member to become unwedged.
