ABSTRACT:
A single control lever mounted on a pivot assembly is movable in an arc in first and second directions in one plane to impart motion through a cam arrangement to a first push rod and cable assembly so that the first push rod and cable assembly moves proportionally to the movement of the lever in either the first or second direction. The same control lever is movable in an arc in third and fourth directions in a second plane normal to the first plane to impart longitudinal motion to a second push rod and cable assembly affixed to the pivot assembly. A resilient means is incorporated in the pivot assembly to resiliently bias the single control lever to a neutral position in the first plane. A gating plate is affixed to the bracket supporting the pivot assembly and limits the travel of the single control lever to a predetermined path.
