Abstract
Abstract A foot valve and brake pedal assembly for use in a truck of the cab-over-engine (COE) type is disclosed herein. The truck itself includes a cab located over the truck's engine and having a front windshield and a front vertical firewall located below the windshield and defining a forwardmost extend of the cab's entire near the driver's feet. The cab also includes a nose hood mounted for pivotal movement between a closed position in front of the firewall and an opened position for gaining access to the firewall externally of the cab. The foot valve and brake pedal assembly is mounted to the firewall in a way which allows it to be removed as an assembled unit from outside the cab when the nose hood is in its opened position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
258 words
In a truck of the cab-over engine type including a cab which is located over the truck's engine andwhich has a front windshield, a front vertical firewall located below said windshield and defining the forwardmost extent of the cab's lower interior near the driver's feet, and a nose hood mounted for pivotal movement between a closed position in front of said firewall for preventing external access to the firewall and an opened position for gaining access to said firewall externally of said cab, the improvement comprising: (a) a foot valve and brake pedal assembly including a foot valve, a brake pedal and means including a support plate for disengageably connecting the foot valve and brake pedal together in an operating condition, such that said foot valve is manually disengeable from said support plate and said brake pedal, and (b) means disengagabely connecting said support plate to said firewall such that (i) said brake pedal is located on the interior side of said firewall within the cab, (ii) said foot valve is located on the exterior side of said firewall behind the nose hood when the latter is in its closed position, but easily accessible from outside the cab when the hood is in its opened position, and (iii) said assembly including said foot valve, support plate and brake pedal are manually disconnectable and removable from said cab when said nose hood is in its opened position, whereby said foot valve is manually separable from said support plate after the entire brake assembly has been disconnected from the firewall.

In a truck of the cab-over engine type including a cab which is located over the truck's engine andwhich has a front windshield, a front vertical firewall located below said windshield and defining the forwardmost extent of the cab's lower interior near the driver's feet, and a nose hood mounted for pivotal movement between a closed position in front of said firewall for preventing external access to the firewall and an opened position for gaining access to said firewall externally of said cab, the improvement comprising: (a) a foot valve and brake pedal assembly including a foot valve, a brake pedal and means including a support plate for disengageably connecting the foot valve and brake pedal together in an operating condition, such that said foot valve is manually disengeable from said support plate and said brake pedal, and (b) means disengagabely connecting said support plate to said firewall such that (i) said brake pedal is located on the interior side of said firewall within the cab, (ii) said foot valve is located on the exterior side of said firewall behind the nose hood when the latter is in its closed position, but easily accessible from outside the cab when the hood is in its opened position, and (iii) said assembly including said foot valve, support plate and brake pedal are manually disconnectable and removable from said cab when said nose hood is in its opened position, whereby said foot valve is manually separable from said support plate after the entire brake assembly has been disconnected from the firewall.
Claim 3
Dependent Claim
38 words
The improvement according to claim 1 wherein said support plate includes a flanged member for pivotally supporting said brake pedal, and a main plate shaped member for detachable connection to said firewall and for supporting said foot valve.
Claim 4
Dependent Claim
27 words
The improvement according to claim 1 wherein said assembly includes a pin for pivotally supporting said brake pedal in a downwardly suspended manner from its top end.
Claim 5
Dependent Claim
125 words
The improvement according to claim 3 wherein said assembly includes an actuating plunger, and wherein said brake pedal includes a substantially straight lever connected at one end of said pivot pin and positioned laterally to one side of said plunger, said lever carrying a plunger actuating flange near its pivot connected end and extending laterally to one side of said lever directly over said plunger and said lever supporting a foot pad at its other end, said foot pad including a segment extending laterally to one side of said lever, said segment having a laterally most edge located laterally beyond a normal plane extending through the center of said plunger, whereby said foot pad is in direct alignment with said plunger and plunger actuation flange.
Claim 6
Dependent Claim
