Claim 1

Independent Claim 167 words

In an automotive vehicle the combination comprising a throttle pedal, a carburetor, a carburetor throttle, linkage means interconnecting the throttle pedal and the carburetor throttle, said linkage means comprising a first link and a second link, means pivotally connecting one end of said first link to one end of said second link, the other end of said first link connected to said throttle pedal, the other end of said second link being pivotally anchored, means coupled to said carburetor throttle and to said first link at a position intermediate the ends thereof, and means operatively controlling said second link such that when the speed of the automotive vehicle is below a predetermined lImit, said means pivotally connecting is maintained in one position in which movement of said throttle is controlled by movement of said first link about said one position and, when the speed of the vehicle exceeds said predetermined limit, said means pivotally connecting is moved in a direction moving said throttle toward the closed position.

Claim 2

Dependent Claim 167 words

In an automotive vehicle the combination comprising a throttle pedal, a carburetor, a carburetor throttle, linkage means interconnecting the throttle pedal and the carburetor throttle, said linkage means comprising a first link and a second link, means pivotally connecting one end of said first link to one end of said second link, the other end of said first link connected to said throttle pedal, the other end of said second link being pivotally anchored, means coupled to said carburetor throttle and to said first link at a position intermediate the ends thereof, and means operatively controlling said second link such that when the speed of the automotive vehicle is below a predetermined lImit, said means pivotally connecting is maintained in one position in which movement of said throttle is controlled by movement of said first link about said one position and, when the speed of the vehicle exceeds said predetermined limit, said means pivotally connecting is moved in a direction moving said throttle toward the closed position.

Claim 3

Dependent Claim 52 words

The combination of claim 1 in which said means operatively controlling comprises an electromagnet and switch means coupled to said electromagnet for energizing said electromagnet when the speed of the vehicle is below said predetermined speed limit and for de-energizing said electromagnet when the speed of the vehicle exceeds said predetermined limit.

Claim 4

Dependent Claim 57 words

The combination of claim 2 in which said switch means includes a relay having a winding and an armature, said armature being positioned to energize said electromagnet when said winding is energized and to de-energize said electromagnet when said winding is de-energized, and means responsive to the vehicle reaching said predetermined speed limit for de-energizing said winding.

Claim 5

Dependent Claim 61 words

The combination of claim 3 in which said last mentioned means comprises a normally conducting solid state switching means having an output circuit coupled to energize said winding and a control electrode, and means coupled to said control electrode for switching said solid state switching means to a non-conducting state when the speed of the vehicle exceeds the predetermined speed limit.

Claim 6

Dependent Claim 151 words

In an automobile vehicle, the combination comprising a throttle pedal, a carburetor, a carburetor throttle, linkage means interconnecting the throttle pedal and the carburetor throttle, said linkage means comprising a link having one end connected to said throttle pedal, a moveable pivotal connection pivotally mounting the other end of said link and means coupled intermediate the ends of said link and said carburetor throttle for controlling the movement of said carburetor throttle in accordance with the movement of said accelerator pedal, and means operatively coupled to said linkage means for maintaining said moveable pivotal connection in one position when the speed of the vehicle is below a predetermined speed level and for moving said moveable pivotal connection to a second position and in a direction to move said carburetor throttle valve toward a closed position when the speed of the automotive vehicle is equal to or above said predetermined speed limit.

Claim 7

Dependent Claim 151 words

In an automobile vehicle, the combination comprising a throttle pedal, a carburetor, a carburetor throttle, linkage means interconnecting the throttle pedal and the carburetor throttle, said linkage means comprising a link having one end connected to said throttle pedal, a moveable pivotal connection pivotally mounting the other end of said link and means coupled intermediate the ends of said link and said carburetor throttle for controlling the movement of said carburetor throttle in accordance with the movement of said accelerator pedal, and means operatively coupled to said linkage means for maintaining said moveable pivotal connection in one position when the speed of the vehicle is below a predetermined speed level and for moving said moveable pivotal connection to a second position and in a direction to move said carburetor throttle valve toward a closed position when the speed of the automotive vehicle is equal to or above said predetermined speed limit.

Claim 8

Dependent Claim 60 words

The combination of claim 5 in which said means operatively coupled to said linkage means comprise an electromagnet and means coupled to said electromagnet for energizing said electromagnet when the speed of the vehicle is below said predetermined speed level and for de-energizing said electromagnet when the speed of the vehicle is equal to or above said predetermined speed level.

Claim 9

Dependent Claim 74 words

The combination of claim 5 in which said means operatively coupled to said linkage means comprises electromagnetic means acting on said linkage means, a source of electrical energy and means for energizing said electromagnetic means from said source of electrical energy when the speed of the vehicle is below said predetermined speed level and for de-energizing said electromagnetic means when the speed of the vehicle is equal to or exceeds said predetermined speed level.

Claim 10

Dependent Claim 43 words

The combination of claim 6 and further comprising means coupled to said linkage means for moving said pivotal connection to said second position upon movement of said throttle pedal to open said carburetor throttle valve at any time said electromagnetic means is de-energized.

Claim 11

Dependent Claim 48 words

The combination of claim 5 and further comprising a second link pivotally anchored at one end, the other end thereof being pivotally connected to said other end of said first mentioned link, said means operatively coupled to said linkage means includes means operatively coupled to said second link.

Claim 12

Dependent Claim 58 words

The combination of claim 9 in which means operatively coupled to said second link comprises an electromagnetic meAns and means for energizing said electromagnetic means when the speed of the vehicle is below said predetermined speed level and for de-energizing said electromagnetic means when the speed of the vehicle is equal to or above said predetermined speed level.
