Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A vehicle clutch and brake actuating means comprising, a clutch and brake pedal pivotally mounted on a vehicle for pivotal movement through a clutch operating phase and a brake operating phase, at least one clutch for controlling the operation of a transmission including means for engaging and disengaging the clutch, a brake for braking the transmission including means for engaging and disengaging the brake, means connecting said pedal with said clutch and brake engaging and disengaging means to sequentially disengage said clutch and engage said brake, means supporting a starter safety switch for engagement with said clutch and brake pedal as said pedal initially swings through the brake operating phase of pivotal movement, means resiliently mounted for engaging said pedal to increase the reaction force on said pedal as said pedal swings through the brake operating phase to thereby indicate to the operator the brake operating phase of pedal movement.
Claim 2
Dependent Claim
150 words
A vehicle clutch and brake actuating means comprising, a clutch and brake pedal pivotally mounted on a vehicle for pivotal movement through a clutch operating phase and a brake operating phase, at least one clutch for controlling the operation of a transmission including means for engaging and disengaging the clutch, a brake for braking the transmission including means for engaging and disengaging the brake, means connecting said pedal with said clutch and brake engaging and disengaging means to sequentially disengage said clutch and engage said brake, means supporting a starter safety switch for engagement with said clutch and brake pedal as said pedal initially swings through the brake operating phase of pivotal movement, means resiliently mounted for engaging said pedal to increase the reaction force on said pedal as said pedal swings through the brake operating phase to thereby indicate to the operator the brake operating phase of pedal movement.
Claim 3
Dependent Claim
98 words
A vehicle clutch and brake actuating means as set forth in claim 1 including a return spring connected to said brake pedal for returning said pedal to a normally retracted position, a lever pivotally supported for pivotal movement on an axis coincidental with the axis of rotation of said clutch and brake pedal, a return spring connected to said lever for returning said lever to a normally retractive position, a return stop defining the retracted position of said lever, said lever engages said pedal only during the brake operating phase to provide increased reaction force on said pedal.
Claim 4
Dependent Claim
81 words
A vehicle clutch and brake actuating means as set forth in claim 1 including means defining a pivotal axis for said clutch and brake pedal, a switch lever pivotally mounted on an axis coincidental with the clutch and brake pedal axis, a return spring connected to said switch lever to normally retract switch lever to a normally retractive position, means mounting said starter safety switch on said switch lever to engage said pedal as it swings through its brake operating phase.
Claim 5
Dependent Claim
89 words
A vehicle clutch and brake actuating means as set forth in claim 1 including means defining a pivotal axis for said clutch and brake pedal, a return spring connected to said pedal to return it to its normally retractive position, a lever pivotally supported on an axis coincidental with the axis of said brake pedal, a return spring connected to said lever to return said lever to its normally retracted position for engagement with said pedal as said pedal swings into the brake operating phase of its pivotal movement.
Claim 6
Dependent Claim
84 words
A vehicle clutch and brake actuating means as set forth in claim 1 including means providing the pivotal axis for said clutch and brake pedal, a switch lever pivotally mounted on an axis coincidental with the pivotal axis of said pedal, a return spring connected to said switch lever to return it to a normally retracted position, means supporting said neutral safety switch on said switch lever for engaging said pedal when said pedal swings through its pivotal path initiating the brake operating phase.
Claim 7
Dependent Claim
111 words
A vehicle clutch and brake actuating means as set forth in claim 1 including a support bracket, means defining a pivotal axis supporting said pedal on said support bracket, a switch lever pivoting about an axis coincidental with the pivotal axis of said lever, a return spring connected to said pedal for retracting said pedal to its normally retracting position, a return spring connected to said switch lever for returning said lever to its normally retracted position, a rest stop engaging said switch lever defining its normally retracted position, means supporting said starter switch on said switch lever for engaging said pedal during initial pivotal movement through the brake operating phase.
Claim 8
Dependent Claim
126 words
A vehicle clutch and brake actuating means as set forth in claim 1 including a support bracket pivotally supporting said pedal and defining a pivotal axis for said pedal, an adjustable pedal return stop on said bracket, a return spring connected to said pedal for returning said pedal to engage said return stop to define the beginning of the clutch operating phase, a switch lever pivotally mounted on said bracket, means supporting said starter safety switch on said switch lever, a lever stop on said bracket, a spring normally retracting said switch lever to engage said lever stop and define the beginning of the brake operating phase and thereby engage said starter safety switch and increase the reaction force on said lever when operating said pedal.
Claim 9
Dependent Claim
80 words
A vehicle clutch and brake actuating means as set forth in claim 1 including a bracket, a switch lever, a pin pivotally supporting said pedal and said switch lever, a pedal rest stop engaging said pedal, a lever rest stop engaging said switch lever, resilient means returning said lever and said pedal to their normally retracted positions thereby engaging said rest stops and defining an initial clutch operating phase and a subsequent brake operating phase of the pedal pivotal movement.
Claim 10
Dependent Claim
52 words
A vehicle clutch and brake actuating means as set forth in claim 1 wherein said pedal defines a foot pedal, a bracket pivotally supporting said foot pedal, an adjustable rest stop for engaging said pedal in its normally retractive position thereby defining the initial clutch operating phase of the pedal pivotal movement.
Claim 11
Dependent Claim
110 words
A vehicle clutch and brake actuating means as set forth in claim 1 including a bracket mounted on the vehicle chassis, a pin supported on said bracket for pivotally supporting said pedal, a switch lever pivotally mounted for pivotal movement on said pin, a starter safety switch mounted on said switch lever, a rest stop on said bracket for engaging said switch lever in its normally retractive position, a return spring for normally retracting said pedal in its normally retractive position, a second spring for returning said switch to its normally retractive position to provide increased reaction for said pedal when said pedal is pivoted through the brake operating phase.
