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.
Claims7
An engine control linkage comprising:
- a housing;
- a first shaft rotatably mounted in the housing;
- a second shaft rotatably mounted in the housing;
- coupling means associated with the housing and associating the first shaft with the second shaft for allowing rotation of the second shaft relative the housing only upon rotation of the first shaft;
- first lever means fixedly associated with the second shaft for rotation therewith;
- second lever means rotatably mounted about the second shaft;
- third lever means rotatably mounted about the first shaft;
- said first and third lever means each engageable with the second lever means for rotating said second lever means in a first rotative direction relative the second shaft;
- and
- resilient means associated with the second shaft and the first and second lever means for urging the second lever means in a second rotative direction to engage the first lever means in a predetermined position relative the first lever means.
