  • Patent number: 5417127
    Abstract: A portable rod-like device for depressing a vehicle pedal, such as an accelerator or a brake pedal to a predetermined setting and maintaining that setting in the form of a screw-threaded rod and a mating screw-threaded nut having a hook. The nut rides up the screw-threaded rod and engages the steering wheel of the vehicle while the other end of the rod engages the pedal. The rod depresses the accelerator pedal against spring pressure while the engine is operating and the accelerator pedal is depressed to a point whereby a predetermined setting has been reached on the tachometer of the vehicle, and maintained at that setting. The device can be finely adjusted in small increments. The foot at the free end of the rod frictionally engages the accelerator pedal and can be mounted in either a fixed position or can be swivel mounted.
