23,857. Freakley, W., and Bill, R. Nov. 20. Road rollers.-A traction wheel for a road roller consists of a plate a of metal, a hub b, and a number of circular holes near the periphery each containing a ring d of solid india-rubber or other resilient material. The outer part of the plate a is covered on each side by a plate e, one of which carries a number of bosses each receiving a bolt and fitting into a hole in the plate a. The plates e are formed integral with the tyre, or a tyre seat, and allow a sliding movement of the central plate. A resilient ring may be inserted between the rim and the edge of the plate, and, to make the wheel dirtproof and waterproof, the side plates are continued to end in a flange, between which and a flange on the hub a rubber ring is held.
