ABSTRACT:
A governor and control linkage having a first manually operated actuator provides for setting of a shaft and a control arm at a particular operating position through a coupling. The coupling locks the shaft in the aforedescribed desired position while allowing a second actuator to temporarily reposition the control arm at any intermediate setting without disturbing the manual setting. A resilient member is included to return the control arm to the manual setting on release of the second actuator. The prepositionable shaft is movable only in response to the first actuator.
