ABSTRACT:
A control lever mechanism for controlling the operative position of a plurality of control valves of a hydraulic distributor by coupling movement of a control lever into selected motion of a pair of rotatable output shafts controlling operation of the valves. Movement of the control lever in planes extending in a longitudinal, transverse, or combination of these directions, is transmitted to the output shaft through interconnecting linkages employing a plurality of spherical joints. The control lever mechanism also includes provisions to protect the linkages from being adversely affected by the introduction of foreign substances such as dirt and other elements.
