Abstract
Abstract A means for controlling the service brakes and both engines of a dual drive train vehicle having a pair of operator stations. Each station has manually actuated brake and throttle valves capable of metering air pressure respectively to the service brakes and an engine control means. A selector valve directs air pressure to the valves in only one station and check valve means isolates the service brakes and the engine control means from the valves in the other station. An electrical circuit is provided to permit independent control of either of the two engines during starting.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
Control means for a vehicle having braking means, engine means and a pair of operator stations comprising: brake and throttle valve means for each station; selector valve means for directing fluid pressure to the valve means in a selected one of the stations; first cylinder means operatively connected with braking means on the vehicle and being in fluid communication with the brake valve means; second cylinder means operatively connected with the engine means and being in fluid communication with the throttle valve means; and check valve means for isolating the brake and throttle valve means in the other station from communication with the cylinder means.
Claim 2
Dependent Claim
105 words
Control means for a vehicle having braking means, engine means and a pair of operator stations comprising: brake and throttle valve means for each station; selector valve means for directing fluid pressure to the valve means in a selected one of the stations; first cylinder means operatively connected with braking means on the vehicle and being in fluid communication with the brake valve means; second cylinder means operatively connected with the engine means and being in fluid communication with the throttle valve means; and check valve means for isolating the brake and throttle valve means in the other station from communication with the cylinder means.
Claim 3
Dependent Claim
47 words
The invention according to claim 1, wherein: the brake valve means is spring biased to a position in which fluid pressure is directed to the first cylinder means and is movable to a position in which metered exhaust of pressure from the first cylinder means is permitted.
Claim 4
Dependent Claim
46 words
The invention according to claim 1, wherein: the throttle valve means is spring biased to a position in which atmospheric pressure is present in the second cylinder means and is movable to a position in which metered fluid pressure is directed to the second cylinder means.
Claim 5
Dependent Claim
85 words
The invention according to claim 1, wherein: the brake valve means is spring biased to a position in which fluid pressure is directed to the first cylinder means and is movable to permit metered exhaust of pressure from the first cylinder means; and the throttle valve means is spring biased to a position in which communication between the source of fluid pressure and the second cylinder means is blocked and is movable to permit metered fluid pressure to be admitted to the second cylinder means.
Claim 6
Dependent Claim
120 words
Control means for a vehicle having braking means, engine means and a pair of operator stations comprising: brake and throttle valve means for each station; fluid valve means for directing fluid pressure to the brake and throttle valve means in a selected one of the stations; control means for shifting said fluid valve means; first cylinder means operatively connected with the braking means on the vehicle and being in fluid communication with the brake valve means; second cylinder means operatively connected with the engine means on the vehicle and being in fluid communication with the brake valve means; and check valve means for isolating the brake and throttle valve means in the other station from communication with the cylinder means.
Claim 7
Dependent Claim
120 words
Control means for a vehicle having braking means, engine means and a pair of operator stations comprising: brake and throttle valve means for each station; fluid valve means for directing fluid pressure to the brake and throttle valve means in a selected one of the stations; control means for shifting said fluid valve means; first cylinder means operatively connected with the braking means on the vehicle and being in fluid communication with the brake valve means; second cylinder means operatively connected with the engine means on the vehicle and being in fluid communication with the brake valve means; and check valve means for isolating the brake and throttle valve means in the other station from communication with the cylinder means.
Claim 8
Dependent Claim
38 words
The invention according to claim 5, wherein said control means comprises; an electrically actuated solenoid means connected to fluid valve means; and manually actuated switch means for selectively connecting the solenoid means with a source of electrical energy.
Claim 9
Dependent Claim
21 words
The invention according to claim 5, wherein said control means comprises a manual control means connected with said fluid valve means.
Claim 10
Dependent Claim
86 words
Control means for a vehicle having braking means, an engine, and a pair of operator stations comprising: first and second brake valves operatively connected for actuation of the braking means; first and second throttle valve means operatively connected for control of the engine; said first brake and first throttle valves located in one of said stations; said second brake and second throttle valves located in the other of said stations; valve means for selectively rendering said first valves inoperative while simultaneously rendering said second valves operative.
Claim 11
Dependent Claim
86 words
Control means for a vehicle having braking means, an engine, and a pair of operator stations comprising: first and second brake valves operatively connected for actuation of the braking means; first and second throttle valve means operatively connected for control of the engine; said first brake and first throttle valves located in one of said stations; said second brake and second throttle valves located in the other of said stations; valve means for selectively rendering said first valves inoperative while simultaneously rendering said second valves operative.
