ABSTRACT:
A linkage assembly coupled between a pedal, rotatable from a neutral position in either of two directions, and a transmission and a carburetor or fuel injector. The linkage assembly includes a crank rotatable in either of two directions in response to the rotation of the pedal from the neutral position and a pair of arcuate links connected between the crank and a control rod which moves in a single direction in response to movement of the crank in either direction, the carburetor increasing the speed of a vehicle engine as the rod moves in the single direction. The assembly also includes other linkage which controls the transmission to shift the vehicle either into forward or reverse drive, depending on the direction of movement of the pedal from the neutral position, at various drive ratios.
