Vehicle speed controlled throttle governor

Claim 2

In combination with a vehicle including an engine throttle control portion shiftable along a predetermined path between first and second fully open and fully closed limit positions, vehicle speed controlled means defining first and second limit abutments spaced apart and along said path, the spacing between said limit abutments being less than the spacing between said first and second limit positions, said vehicle speed controlled means being operative to shift said limit abutments along said path in the directions of movement of said throttle control portion toward said fIrst and second limit positions in response to increase and decrease, respectively, in the speed of said vehicle, said first and second limit abutments being engageable by said throttle control portion for limiting shifting of the latter along said path toward said first and second positions, respectively, said first limit abutment being supported for shifting toward and away from said second limit abutment between a first location adjacent said second abutment and a second location remote from said second abutment and means yieldingly urging said first abutment toward said first location.

Claim 3

The combination of claim 1 wherein said throttle control portion is mounted in a carrier therefor shiftable along said path, said vehicle speed controlled means being shiftable relative to said carrier transversely of said path for shifting out of registry with said limit abutments.

Claim 4

The combination of claim 2 including remotely actuatable control means operatively associated with said throttle control portion for selectively shifting said throttle control portion transversely of said path out of registry with said limit abutments.

Claim 5

In combination, a wheeled vehicle including a throttle portion shiftable between open and closed positions and a drive assembly driven at speeds proportional to the speed of movement of said vehicle, a throttle control operatively connected between said drive assembly and said throttle portion including means operative to limit shifting of said throttle portion toward said open position upon initial acceleration of said vehicle from a stand still and low speed movement and to thereafter allow further movement of the throttle portion toward said open position in response to increasing speed of said vehicle, said throttle control also including means operative to limit shifting of said throttle portion toward said closed position upon initial deceleration of the vehicle from high speed movement and to thereafter allow further movement of the throttle portion toward said closed position in response to decreasing speed of said vehicle.

Claim 6

In combination, a wheeled vehicle including a throttle portion shiftable between open and closed positions and a drive assembly driven at speeds proportional to the speed of movement of said vehicle, a throttle control operatively connected between said drive assembly and said throttle portion including means operative to limit shifting of said throttle portion toward said open position upon initial acceleration of said vehicle from a stand still and low speed movement and to thereafter allow further movement of the throttle portion toward said open position in response to increasing speed of said vehicle, said throttle control also including means operative to limit shifting of said throttle portion toward said closed position upon initial deceleration of the vehicle from high speed movement and to thereafter allow further movement of the throttle portion toward said closed position in response to decreasing speed of said vehicle.

Claim 7

The combination of claim 4 wherein said means limiting shifting of said throttle portion toward said open position defines a yieldable limit which may be overridden by an increase of pressure acting on said throttle portion to shift the latter toward its open position.

Claim 8

The combination of claim 4 wherein said throttle control includes a vehicle speed driven centrifugal governor driven at a speed proportional to vehicle speed.

Claim 9

The combination of claim 4 wherein said throttle control includes remotely actuatable control override means operative, when actuated, to effectively disconnect said control from said drive assembly.

Claim 10

In combination, first and second members supported for relative oscillation along a predetermined path, said first member including first and second abutment surfaces spaced along said path and said second member including abutment element means supported therefrom for shifting laterally of said path between a first position engageable by said surfaces and a second position out of registry with said surfaces, said element means having a pair of abutment faces abuttingly engageable with said surfaces upon relative oscillation of said members when said element is in said first position, one abutment surface of said first member being supported therefrom for shifting relative to the latter longitudinally of said path between near and far positions relative to the other abutment surface, means yieldingly biasing said one abutment surface toward said near position, a vehicle having a throttle control oscillatable between open and closed positions and a vehicle speed driven member oscillatable in response to increase and decrease in speed of said vehicle, means connecting said throttle control to one of said first and second members and said vehicle speed driven member to the other of said first and second members.

Claim 11

In combination, first and second members supported for relative oscillation along a predetermined path, said first member including first and second abutment surfaces spaced along said path and said second member including abutment element means supported therefrom for shifting laterally of said path between a first position engageable by said surfaces and a second position out of registry with said surfaces, said element means having a pair of abutment faces abuttingly engageable with said surfaces upon relative oscillation of said members when said element is in said first position, one abutment surface of said first member being supported therefrom for shifting relative to the latter longitudinally of said path between near and far positions relative to the other abutment surface, means yieldingly biasing said one abutment surface toward said near position, a vehicle having a throttle control oscillatable between open and closed positions and a vehicle speed driven member oscillatable in response to increase and decrease in speed of said vehicle, means connecting said throttle control to one of said first and second members and said vehicle speed driven member to the other of said first and second members.

Claim 12

The combination of claim 8 wherein said one member comprises saId first member.
