Abstract
Entirely mechanical assembly attachable to accelerator pedal of motor vehicle for selective setting of fuel flow. Chosen setting can be instantly overridden by pedal depression or be completely cancelled by tapping brake pedal. Set position is determined by longitudinal series of transverse slots on lengthwise-reciprocable control shaft, which slots are engagable by unidirectional latch; latter is disengaged by small rotation of shaft to bring smooth surface of shaft to sliding registration with latch. Cable connection between brake pedal and control shaft converts vertical movement of pedal to rotational movement of shaft.
Claims5
A fuel control assembly comprising in combination:
- an elongated guide channel having a proximate end and a distant end, and means for mounting said channel in the operator's compartment of a motor vehicle between a distant fuel control element and a proximate hand-reach position for a vehicle operator,
- an operating shaft movable lengthwise along said guide channel, having proximate and distant lengths extending beyond the respective ends of the guide channel, said shaft being at least partially rotatable axially along the channel and bearing a longitudinal series of engagement means located laterally-adjacent a smooth length of said shaft,
- unidirectional latch means carried by the guide channel and positionable by such rotation of the shaft to engage a selected unit of said engagement means and thereby restrain lengthwise movement of the shaft toward its proximate end only, and alternately by counterrotation of the shaft to slidingly overlie said smooth length of the shaft and thereby permit lengthwise shaft movement in either direction, unrestrained by the latch means,
- means for coupling the distant length of said shaft with said fuel control element to maintain a set level of fuel flow responsive to the amount of distant extension of the shaft from the guide channel, and
- means for releasably setting the distant end of said shaft at a selected amount of extension from said guide channel, thereby holding the coupled fuel supply element in position to effect corresponding fuel flow.

- means for coupling the distant length of said shaft to said fuel control element to maintain a set level of fuel flow responsive to the amount of distant extension of the shaft from the guide channel, including telescopic means permitting reciprocable movement of the coupled fuel control element beyond said set position so as to temporarily override the same, the proximate length of said operating shaft carrying a collar displaceable therealong between the respective proximate ends of the shaft and of the guide channel and being selectively anchorable therealong, thereby determining the amount of extension of said distant length from the guide channel and setting a selected level of fuel flow, and
- means responsive to movement of a brake pedal in said operator's compartment, for disengaging said latch means by counterrotation of said shaft, said disengaging means comprising a curved longitudinally movable wire having its respective ends secured to said brake pedal and to said shaft, and having an intermediate length disposed within a flexible, arcuate sheath extending between the brake pedal and the shaft.
