Claim 3

A gauge for checking and determining the proper adjustment of an adjustable control linkage operatively connecting an engine fuel feed control with a rockable throttle valve lever operatively connected with the throttle valve of an automatic transmission, comprising, a planar base member, said base member having clamping means formed in one end thereof for rigidly securing said base member to a transmission, a gauging plate operatively disposed on said base member in a plane parallel to the plane of said base member, said gauging plate having a plurality of radially disposed indications thereon which indicate different positions taken by the throttle lever as determined by the engine fuel feed control position, and securing means for slidably and pivotally mounting said gauging plate on said base member to a fixed station whereby the base member can be adjusted and secured so that a first of said indications is aligned with said throttle valve lever when the throttle valve lever is rocked to a first position and whereby a second of said indications on said fixed base member is aligned with said throttle valve lever when the throttle valve lever is turned in an opposite direction to an extreme position corresponding to a full throttle position and whereby a third of said indications on said fixed base member can be aligned with the throttle valve lever so that the linkage can be accurately adjusted and connected to the throttle valve lever.

Claim 4

A gauge for checking and determining the proper adjustment of an adjustable control linkage operatively connecting an engine fuel feed control with a rockable throttle valve lever operatively connected with the throttle valve of an automatic transmission, comprising, a planar base member, said base member having clamping means formed in one end thereof for rigidly securing said base member to a transmission, a gauging plate operatively disposed on said base member in a plane parallel to the plane of said base member, said gauging plate having a plurality of radially disposed indications thereon which indicate different positions taken by the throttle lever as determined by the engine fuel feed control position, and securing means for slidably and pivotally mounting said gauging plate on said base member to a fixed station whereby the base member can be adjusted and secured so that a first of said indications is aligned with said throttle valve lever when the throttle valve lever is rocked to a first position and whereby a second of said indications on said fixed base member is aligned with said throttle valve lever when the throttle valve lever is turned in an opposite direction to an extreme position corresponding to a full throttle position and whereby a third of said indications on said fixed base member can be aligned with the throttle valve lever so that the linkage can be accurately adjusted and connected to the throttle valve lever.

Claim 5

A gauge for checking the adjustment of a throttle valve linkage for an automatic transmission comprising an elongated base member having an open end portion with angularly related sides for engaging predetermined sides of a retaining nut, clamping means disposed on one side of said base for engaging the retaining nut, a gauge plate having indicia representative of predetermined stations of a throttle valve lever with respect to a fixed station, and fastener means movably mounting said gauge plate on said base so that predetermined indicia can be aligned with said lever when said lever is in a predetermined position.

Claim 6

A gauge for checking the adjustment of a throttle valve linkage for an automatic transmission comprising an elongated base member having an open end portion with angularly related sides for engaging predetermined sides of a retaining nut, clamping means disposed on one side of said base for engaging the retaining nut, a gauge plate having indicia representative of predetermined stations of a throttle valve lever with respect to a fixed station, and fastener means movably mounting said gauge plate on said base so that predetermined indicia can be aligned with said lever when said lever is in a predetermined position.

Claim 7

The gauge of claim 3 wherein said fastener means comprises an elongated slot in said plate and a retaining bolt secured to said base and extending through said slot to slidably and pivotally mount said plate to said base, and wherein said indicia means comprises a family of radial lines radiating from a point remote from said plate.

Claim 8

A gauge for checking the adjustment of a throttle valve linkage operatively connecting a movable accelerator pedal and a throttle valve lever having a linear edge portion mounted for limited rotation on a transmission housing having a selector lever and a selector lever nut, comprising, an elongated base member having a planar upper surface and having an open end jaw shaped to accommodate said base on said nut, said jaw having a fixed first face formed by a portion of said base deformed inwardly at right angles to said planar surface and having a yieldable second face spaced and directly opposing said first face formed by a spring finger integral with said base and spaced from the first face for clamping the selector lever nut therebetween, said jaw further having third and fourth angularly related nut engaging faces disposed between said first and second faces to guide and securely seat said base on said nut, a sector-shaped gauging plate having an arcuate slot formed therein adjacent to and concentric with the arc of said sector plate and extending substantially across the face of said plate, bolt means extending through said slot and fixed to said base for adjustably securing said plate to said base, said plate having a family of radial lines formed thereon which are alignable with the edge portion of said lever to correspond to different positions of the throttle valve lever when moved by the linkage to control the transmission, a first of said lines being a radial line indicative of a maximum limit of movement of the lever in one direction when disconnected from the linkage, a second of said lines being indicative of the engine idle position of said linkage and said lever, a third of said lines being indicative of the full throttle position of said pedal and said lever and a fourth of said lines being indicative of a forced downshift position of said pedal and lever and disposed beyond said full throttle position.

Claim 9

A gauge for checking the adjustment of a throttle valve linkage operatively connecting a movable accelerator pedal and a throttle valve lever having a linear edge portion mounted for limited rotation on a transmission housing having a selector lever and a selector lever nut, comprising, an elongated base member having a planar upper surface and having an open end jaw shaped to accommodate said base on said nut, said jaw having a fixed first face formed by a portion of said base deformed inwardly at right angles to said planar surface and having a yieldable second face spaced and directly opposing said first face formed by a spring finger integral with said base and spaced from the first face for clamping the selector lever nut therebetween, said jaw further having third and fourth angularly related nut engaging faces disposed between said first and second faces to guide and securely seat said base on said nut, a sector-shaped gauging plate having an arcuate slot formed therein adjacent to and concentric with the arc of said sector plate and extending substantially across the face of said plate, bolt means extending through said slot and fixed to said base for adjustably securing said plate to said base, said plate having a family of radial lines formed thereon which are alignable with the edge portion of said lever to correspond to different positions of the throttle valve lever when moved by the linkage to control the transmission, a first of said lines being a radial line indicative of a maximum limit of movement of the lever in one direction when disconnected from the linkage, a second of said lines being indicative of the engine idle position of said linkage and said lever, a third of said lines being indicative of the full throttle position of said pedal and said lever and a fourth of said lines being indicative of a forced downshift position of said pedal and lever and disposed beyond said full throttle position.
