Abstract
Abstract Apparatus (10) for controlling a plurality (12, 16) of mechanisms, including a pedal (20), a first device (44) for permitting the pedal (20) to move in a substantially straight line to regulate a first mechanism (12), and a second device (24, 58, 60), for permitting the pedal (20) to pivot to regulate a second mechanism (16). In a specific embodiment, the pedal (20) is moved substantially linearly to shift a vehicle transmission control valve (12) into forward, reverse, or neutral positions, whereas the pedal (20) is pivoted to increase engine speed. The second device (24, 58, 60) also prevents linear movement of the pedal (20) when the pedal (20) has been pivoted to preselected amount.
