Abstract

3317. Clarke, B. E. Feb. 10. Slipping of wheels, preventing.-Secured to a wheel or wheel hub, or to an axle in proximity to a wheel of a motorvehicle is a disk carrving a number of pivoted segments forming a complete ring which is surrounded by a tyre of about the same diameter as the running wheel, so that, when side - slip occurs in one direction, the segments in proximity to the road are tilted, and gripping- edges on the segments or on plates attached thereto are 'brought into contact with the ground to prevent further slipping. A similar device is fitted on the opposite side of the vehicle. Fig. 1 shows a disk 3 mounted upon an extension 2 of a rear wheel hub and having a hook-shaped edge 4 engaging correspondingly-shaped recesses in the pivoted segments 5, which are held in their normal position by springs or by a spring plate or disk 12 mounted upon the extension 2. Adjustably secured to each segment is a plate 9, the inner end 10 acting as a stop for the segment, and the outer end having gripping-edges 11, which may be toothed. When side-slip occurs, the segments near the ground are displaced until their sloped tail-pieces abut against the disk 3 and the gripping - edges 11 are brought into operation. In a modification, the segments 5 are normally at an angle to the disk 3, so that very little weight is carried by the tyre surrounding the segments.
