Patented in the German Empire from la. August 190a.

The previously known and executed constructions of divisible rims offer, although show very significant advantages over the usual one-piece However, in, establishments almost all have such disadvantages that a general introduction the same was previously not possible. Above all, it should be noted that the Flange or bolts held together halves of individual, especially American Constructions once consist of an extraordinarily large number of parts, which makes them simplicity and duration of assembly and disassembly is adversely affected, but then also a result in significant additional weight. Other constructions again, in which the secure connection between the two rims is made using a tensioning screw in conjunction with tongue and groove,

ao show the disadvantage that dismantling and assembling can take so long without difficulty is possible when the parts are still bright and clean, but this work becomes significantly more laborious and time-consuming, as soon as rust and impurities cause the tongue to stick more firmly in the groove is, apart from the fact that when driving especially the clamping screw as a result their location easily injuries or Is exposed to fractures, which easily jump off of the tire and, as a result, major accidents as a result. The rim construction described below; avoids all mentioned. Defects, and also shows an unprecedented simplicity.

An embodiment of the present innovation is in the accompanying drawing in Fig. ι in cross section, in Fig. 2 in top view and in Fig. 3 in side view been. . .

The rim consists of two parts; the 'main rim ring α and the clamping ring b. While the former resembles a normal rim of any shape on one side, is on the other; Side a groove c of the appropriate width is turned so that the parallel sides d of the same are not perpendicular to the wheel axis, but at any angle to the same. The cut-open 50 'clamping ring b has a likewise inclined tongue e which fits into the groove and, due to its resilience, can be pulled onto the main ring a , and the tongue e can be brought into engagement with the groove c. When inflating the pneumatic tire, the tire presses itself firmly against the clamping ring due to the air pressure and thereby causes it to be pressed into the groove, as well as a simultaneous reduction in diameter, in that the bevels of the tongue and groove slide on each other, whereby the tire is held firmly in its position, without the clamping ring being able to loosen. The higher you here the load respectively. If the pressure of the tire increases, the more securely the clamping ring is in its position. The dismantling is easy, in such a way that after removal
