Abstract: My invention relates to certain improvements in traction or road engines of the same general construction and function as those for which I have previously filed two applications for patents, bearing date March 7, 1882, and marked "Cases A and B." As in these preceding inventions, the object of my present improvement is, in short, to provide such flexible and elastic connections between the running or traction wheels and the body of the engine and its driving-gear as will adapt the engine to passage over rough roads without involving undue strains upon the working parts. These features of improvement I will fully describe in connection with the other parts shown in the drawings, and then clearly design ate them. Claim: The countershaft composed of two parts, combined with and connected by the links g, sliding block h, with rollers i, and hollow clutch-section j, having guideways to receive the rollers.
