Abstract
Abstract A maximum vehicle speed limiter for use in an automotive vehicle that has a throttle pedal connected to a carburetor throttle valve through a linkage means. This linkage means includes two links which are pivotally connected through a pivotal connection at one end of each of the links. The other end of one of the links is coupled to the throttle pedal, and the other end of the link is pivotally anchored in the automotive vehicle. Means in the form of additional linkage is coupled to the throttle pedal and to a position intermediate the ends of the first mentioned link. When the speed of the automotive vehicle is below a predetermined limit, an electromagnet holds the pivotal connection between the two links in a given position. When this speed is exceeded, the electromagnet is de-energized and the pivotal connection moves into a second position which acts on the linkage connected to the carburetor throttle plate to move this throttle plate towards a closed position, thereby limiting the maximum speed of the automotive vehicle.

Claims Analysis
Total Claims: 12
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
