ABSTRACT:
A control mechanism for actuating multiple valve spools with a single control lever includes a frame member to which a valve assembly having multiple valve spools is assembled. A fixed shaft is mounted in a spaced parallel relationship to said valve spools, with a plurality of motion transfer devices mounted to the fixed shaft which are connected at one end to the valve spools. The other ends of the motion transfer devices are connected to an adapter which is mounted to a spherical pivot in such a way that only one of the valve spools is operated when the lever is reciprocated in a first control direction, only one other valve spool is operated when the lever is reciprocated in a second control direction, and only another valve spool is operated when the lever is twisted up to a predetermined amount. The first, second and third valve spools can be operated one at a time, two at a time or all at once. Additionally, the control mechanism provides for additional motion transfer devices and valve spools to be mounted for operation by auxiliary levers to conveniently provide for additional functions.
