Abstract
Abstract A governor control linkage having a first manually operated actuator and a second manually operated actuator provides for setting of an engine governor control arm at a particular operating position by means of the first manually operated actuator, a coupling and an extensible link interconnected with the governor control arm. The coupling operatively locks the first manually operated actuator relative the setting of the governor control arm while allowing the second actuator to temporarily reposition the governor control arm at an intermediate setting. The extensible link in the first manually operated actuator returns the governor control arm and the second manually controlled actuator to the prepositioned setting upon release of the second actuator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
272 words
A linkage assembly mountable on a console for operating a control arm link, the control arm link positionable between at least a first position for a relatively low operating setting and a second position for a relatively high operating setting; the linkage assembly comprising: bell crank means movable at least between a third and fourth position for positioning said control arm link in various operating positions between at least said first and said second positions; a first actuator including a manually operable portion and an extensible link portion, said first actuator associated with said control arm link by said bell crank means and operably movable to responsively position said bell crank means between at least said third and said fourth positions; a second actuator including a compressible link and a pedal portion, said second actuator spatially removed from said first actuator and associated with said control arm link by said bell crank means and releasably operative to position said bell crank means so that said control arm link is moved at most from a relatively high operating setting to a relatively low operating setting while the manually operable portion of the first actuator remains undisturbed; said extensible link portion extendable by motion of said second actuator for resiliently returning the control arm link to a relatively high operating position upon release of said second actuator; and said compressible link for allowing said control arm link to travel in response to said first actuator beyond the relatively low operating setting while the pedal portion remains undisturbed; said bell crank means interconnecting said extensible link and said compressible link with the control arm link.
Claim 2
Dependent Claim
272 words
A linkage assembly mountable on a console for operating a control arm link, the control arm link positionable between at least a first position for a relatively low operating setting and a second position for a relatively high operating setting; the linkage assembly comprising: bell crank means movable at least between a third and fourth position for positioning said control arm link in various operating positions between at least said first and said second positions; a first actuator including a manually operable portion and an extensible link portion, said first actuator associated with said control arm link by said bell crank means and operably movable to responsively position said bell crank means between at least said third and said fourth positions; a second actuator including a compressible link and a pedal portion, said second actuator spatially removed from said first actuator and associated with said control arm link by said bell crank means and releasably operative to position said bell crank means so that said control arm link is moved at most from a relatively high operating setting to a relatively low operating setting while the manually operable portion of the first actuator remains undisturbed; said extensible link portion extendable by motion of said second actuator for resiliently returning the control arm link to a relatively high operating position upon release of said second actuator; and said compressible link for allowing said control arm link to travel in response to said first actuator beyond the relatively low operating setting while the pedal portion remains undisturbed; said bell crank means interconnecting said extensible link and said compressible link with the control arm link.
Claim 3
Dependent Claim
73 words
The linkage assembly of claim 1 wherein the control arm link includes a third off position relatively less than the relatively low operating position, further wherein the first actuator is operably movable for positioning the control arm link at said off position. further the linkage assembly includes first stop means for limiting motion of said first actuator, and further wherein the assembly comprises second stop means for limiting motion of the second actuator.
Claim 4
Dependent Claim
90 words
The linkage assembly of claim 2 wherein the manually operable portion of the first actuator includes: a first lever arm rotatably positionable at a first, second, and third setting corresponding to the off, relatively low, and relatively high positions of the control arm link; a first link; coupling means for allowing said first link to be positioned by said first lever arm while preventing said first lever arm from being positioned by said first link; second bell crank means for operatively connecting said first link with the extensible link portion.
Claim 5
Dependent Claim
42 words
The linkage assembly as set forth in claim 3 wherein the second actuator comprises a bracket rigidly associated with the console, said pedal portion rotatably mounted in said bracket, the compressible link associating said pedal portion with the first bell crank means.
Claim 6
Dependent Claim
27 words
The linkage assembly as set forth in claim 4 wherein the second stop means comprises a second stop member for limiting the travel of said pedal member.
Claim 7
Dependent Claim
47 words
The linkage assembly as set forth in claim 5 wherein the first stop means comprises a first stop member rigidly associated with the second bell crank and engaging the console upon positioning of the control arm link in the relatively high position by the first lever arm.
Claim 8
Dependent Claim
46 words
The linkage assembly as set forth in claim 4 wherein the second stop means further comprises an elongated arm rigidly affixed at one end to the bracket and extending outwardly therefrom, the elongated arm having adjustably mounted at the other end thereof the second stop member.
Claim 9
Dependent Claim
29 words
The linkage assembly as set forth in claim 1 wherein the extensible link portions includes an extendible linkage and third stop means for limiting extension of the extendible linkage.
Claim 10
Dependent Claim
52 words
The linkage assembly as set forth in claim 8 wherein the extendible linkage is extendible from a first short length to a second relatively longer length and includes resilient means for resiliently biasing the extendible linkage to the first short length; the second relatively longer length determined by the third stop means.
