Abstract

11,719. Roux, E. May 22. Annular wheels. -Motor wheels applied to cycles, agricultural implements, &c. are formed as shown in Figs. 1 and 3. In the form shown in Fig. 1, the wheel or rim A is fitted internally with a triangular framework, the angles of which carry antifriction wheels or rollers B, B<1>, B' having either a concave or a convex periphery, which run on the interior periphery of the wheel or rim A. The framework carries a motor M which may drive the wheel or rim A directly, or indirectly, by being connected with one of the wheels or rollers B, B<1>, B<2> by belt gearing, as shown, or other gearing, the wheels or rollers being adapted to engage with pins, rollers, or bowls on, or by frictional contact with the wheel or rim A. Wheels for vehicles may be constructed on the same principle, without the motors. The application of the invention to a motor bicycle is shown in Fig. 3. In this case, the triangular or polygonal frame is replaced by a cross-bar F carrying guiderollers B<1>, B', the driving roller or wheel B being carried on the fork D', or modifications of this arrangement may be used. The rail of the wheel or rim A may be provided with inclined ratchet teeth, with which spring teeth on the driving-roller B engage.
