Abstract
Abstract A foot actuated control pedal has a transversely disposed locking pin secured thereon which is adapted to cooperate with a T-shaped slot formed on a floor plate to lock the pedal in an operative position when the pedal is depressed and retracted. The pedal is unlocked when it is depressed and moved forwardly against the biasing force of a compression spring and is returned to its upper, neutral position under the influence of a torsion spring.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
146 words
An actuating mechanism comprising a stationary support including a plate member, a lever, first pivot means pivotally mounting said lever on said support, a control member projecting through said plate member, second pivot means pivotally mounting said control member on said lever, first biasing means operatively connected between said support and said lever for urging said lever to pivot about said first pivot means to move said control member to a first position, second biasing means operatively connected between said lever and said control member for urging said control member to pivot about said second pivot means to a second position, and cooperating locking means formed on said control member and said plate member for selectively locking said control member in said second position and for releasing and permitting said control member to return to said first position under the influence of said first biasing means.
Claim 2
Dependent Claim
146 words
An actuating mechanism comprising a stationary support including a plate member, a lever, first pivot means pivotally mounting said lever on said support, a control member projecting through said plate member, second pivot means pivotally mounting said control member on said lever, first biasing means operatively connected between said support and said lever for urging said lever to pivot about said first pivot means to move said control member to a first position, second biasing means operatively connected between said lever and said control member for urging said control member to pivot about said second pivot means to a second position, and cooperating locking means formed on said control member and said plate member for selectively locking said control member in said second position and for releasing and permitting said control member to return to said first position under the influence of said first biasing means.
Claim 3
Dependent Claim
31 words
The invention of claim 1 wherein said first biasing means comprises a torsion spring having a first end attached to said support and a second end thereof engaged with said lever.
Claim 4
Dependent Claim
22 words
The invention of claim 1 wherein said second biasing means comprises a coil spring mounted between said lever and said control member.
Claim 5
Dependent Claim
54 words
The invention of claim 1 wherein said locking means comprises an irregularly shaped slot formed through said plate member and defining a narrow portion and a substantially wider portion and a stop pin secured to said control member having a length sufficient to pass through said wider portion but not through said narrow portion.
Claim 6
Dependent Claim
42 words
The invention of claim 1 further comprising a control valve having a control element positioned closely adjacent to said lever so that upon depression of said control member said lever will engage and move said control element to actuate said control valve.
Claim 7
Dependent Claim
92 words
A foot pedal actuating mechanism comprising a stationary support including a plate member having an irregularly shaped slot formed therethrough defining a narrow portion and a substantially wider portion, a pedal extending through said slot and having a stop pin secured thereon, normally disposed above said slot, said pin having a length sufficient to pass through the wider portion of said slot but not through the narrow portion thereof, and a lever pivotally mounted on said support, below said plate member, and having a lower end of said pedal pivotally mounted thereon.
Claim 8
Dependent Claim
92 words
A foot pedal actuating mechanism comprising a stationary support including a plate member having an irregularly shaped slot formed therethrough defining a narrow portion and a substantially wider portion, a pedal extending through said slot and having a stop pin secured thereon, normally disposed above said slot, said pin having a length sufficient to pass through the wider portion of said slot but not through the narrow portion thereof, and a lever pivotally mounted on said support, below said plate member, and having a lower end of said pedal pivotally mounted thereon.
Claim 9
Dependent Claim
61 words
The invention of claim 6 further comprising first biasing means operatively connected between said support and said lever for urging said lever upwardly toward said plate member and second biasing means operatively connected between said lever and said pedal for urging said pedal to a retracted position wherein said stop pin is normally positioned over the narrow portion of said slot.
Claim 10
Dependent Claim
41 words
The invention of claim 6 further comprising a control valve having a control element positioned adjacent to and below said lever whereby depression of said pedal will engage and move said control element by said lever to actuate said control valve.
