Upon the back end of the cross shaft, S,is mounted a shaft governor so arranged that when theweights move outward they rotate the pin, G, about theshaft center, changing its angle with reference to the shaftand the crank pin, /, but preserving a constant throw orradius of eccentricity. The governor pin, G, is connectedby a vertical rod to a pin, P, in the arm, A. The arm, A,is connected at one end to a pin upon the crank, B, whichis keyed to the shaft, t, and is thus constantly vibratingthrough a fixed angle equal to that

The arm, A,is connected at one end to a pin upon the crank, B, whichis keyed to the shaft, t, and is thus constantly vibratingthrough a fixed angle equal to that of the wrist plate, W,while the engine is in motion. The other end of the lever,A, is connected by a short link, L, to the variable wristplate. Now in the little outline sketch marked Fig. 2,as the shaft, S, is rotated, the end of the lever, A H, ismoved up and down through the arc, A A, about thepoint, H, as a center, and there is no tendency to movethe plate, X, about its center.
