    Abstract: A wheel rim includes two centripetal flanges respectively centripetally formed on an inner and an outer portion of a drop-center portion of the wheel rim having different displacements of the two centripetal flanges respectively deviated from a longitudinal center plane centrally defined between an inner rim flange and an outer rim flange of the wheel rim, with the longitudinal center plane being projectively perpendicular to a central axle axis of the wheel rim, thereby simultaneously satisfying two types of cars, one having a larger off-set and the other having a smaller off-set of each wheel disk as respectively deviated from the longitudinal center plane of each wheel rim.

    Abstract: A wheel tread adjusting device has a flat plate provided with a plurality of holes. Two of the holes align with the jack screw bores normally present in a tapered sleeve-type hub to mount the plate to the tapered sleeve. A cut-out bore allows the plate to rest flush against the tapered sleeve without interfering with the normally present lug bolts. Two additional bores are positioned radially outside of the tapered sleeve and hold jack screws to unwedge the tapered sleeve from the hub. An adjustment rod is selectively engageable with either of two adjustment bores in the plate. Another portion of the rod can be threaded through a bracket mounted to the end of the axle, or through a lug bolt bore in the hub of an outer wheel, if dual wheels are present. The structure is extremely simple, uses the normally present bores to the maximum extent, and is made predominantly of standard available parts.

    Abstract translation: 轮胎胎面调节装置具有设置有多个孔的平板。 两个孔与通常存在于锥形套筒型毂中的千斤顶螺丝孔对准以将板安装到锥形套筒。 切口孔允许板平齐地抵靠锥形套筒，而不会干扰通常存在的凸耳螺栓。 两个额外的孔位于锥形套筒的径向外侧并保持千斤顶螺钉，以使锥形套筒从轮毂上解开。 调节杆可选择性地与板中的两个调节孔中的任一个接合。 如果存在双轮，杆的另一部分可以穿过安装到轴的端部的支架，或者通过外轮的轮毂中的凸耳螺栓孔。 该结构非常简单，最大程度地使用通常存在的孔，并且主要由标准可用部件制成。
