Transmission control mechanism

Claim 2

A control apparatus for transmissions and the like comprising a shift actuator lever universally pivotable about a fixed point, a movable control shaft having a longitudinal axis and a connection, said connection including a first element fixed to said shaft and a second element connected to said first element for translational movement with said first element and pivotal movement relative to said first element about an axis parallel to said shaft axis, said lever being secured to said second element for universal pivotal movement about a fixed point on said second element in response to said translational and pivotal movements of said second element.

Claim 3

The apparatus of claim 1 wherein said first element includes a pair of arms extending from said shaft, said second element being in the form of a clevis having a yoke portion pivotally connected to said arms and a shank portion extending from said yoke portion, one of said shank portion and lever having a stud extending thereform and terminating in a partspherical end socketed for universal pivotal movement in the other.

Claim 4

The apparatus of claim 1 wherein said supporting means includes a second shaft rotatable about said axis, a second control member operative to rotate said second shaft about said axis and including a second shift actuator lever pivotal about a second axis in response to rotation of said second shaft about said shaft axis.

Claim 5

The apparatus of claim 3 wherein one of said shafts has a bore rotatably and slidably guiding the other of said shafts.

Claim 6

The apparatus of claim 3 wherein said connection comprises a first element fixed to said first named shaft and a second element connected to said first element for translational movement with said first element and pivotal movement relative to said first element about an axis parallel to said shaft axis, said lever being secured to said second element for universal pivotal movement about a fixed point on said second element in response to said translational and pivotal movements of said second element.

Claim 7

The apparatus of claim 5 wherein said first element includes a pair of arms extending from said first named shaft, said second element being in the form of a clevis having a yoke portion pivotally connected to said arms and a shank portion extending from said yoke portion, one of said shank portion and lever having a stud extending therefrom and terminating in a part-spherical end socketed for universal pivotal movement in the other.

Claim 8

Control apparatus for transmissions comprising: a first shift actuating member movable in a first shifting plane between at least one active position and neutral position; a second shift actuating member movable in a second shifting plane between at least one active position and neutral position, and a third shifting plane between at least one active position and neutral position; first control lever selectively movable in a first control plane, a second control lever selectively movable in a neutral control plane intersected by second and third control planes, said second control lever being selectively movable in said second and third control planes when moved to the respective intersections thereof with said neutral control plane; and shift mechanism interconnected with said control levers and shifting members operable to (1) cause said first shift actuating member to move in said first shifting plane in response to corresponding movement of said first control lever in said first control plane, (2) cause said second shift actuating member to move in said second shifting plane in response to corresponding movement of said second control lever in said second control plane with said first shift actuating member located at any selected position in said first shifting plane, and (3) cause said second shift actuating member to move in said third control plane in response to corresponding movement of said second control lever in said third control plane with said first shift actuating member located at any desired position in said first shifting plane.

Claim 9

Control apparatus for transmissions comprising: a first shift actuating member movable in a first shifting plane between at least one active position and neutral position; a second shift actuating member movable in a second shifting plane between at least one active position and neutral position, and a third shifting plane between at least one active position and neutral position; first control lever selectively movable in a first control plane, a second control lever selectively movable in a neutral control plane intersected by second and third control planes, said second control lever being selectively movable in said second and third control planes when moved to the respective intersections thereof with said neutral control plane; and shift mechanism interconnected with said control levers and shifting members operable to (1) cause said first shift actuating member to move in said first shifting plane in response to corresponding movement of said first control lever in said first control plane, (2) cause said second shift actuating member to move in said second shifting plane in response to corresponding movement of said second control lever in said second control plane with said first shift actuating member located at any selected position in said first shifting plane, and (3) cause said second shift actuating member to move in said third control plane in response to corresponding movement of said second control lever in said third control plane with said first shift actuating member located at any desired position in said first shifting plane.

Claim 10

Apparatus as claimed in claim 7 wherein said first control lever is supported for rotatable movement in said first control plane, and said second control lever is supported for rotatable movement in said second and third control planes and said second control lever is supported for movement along its axis of rotatable movement in said neutral control.

Claim 11

Apparatus as claimed in claim 8 wherein said shift mechanism includes a pair of coaxial rotatable motion transmitting members each of which is connected with one of said shifting members to transmit motion thereto in response to movement of said control lever.

Claim 12

Apparatus as claimed in claim 9 wherein one of said motion transmitting members is movable longitudinally between first and second axial position, said second shift actuating member being positioned in said second shifting plane when said one motion transmitting member is in said first axial position and being positioned in said third shifting plane when said one motion transmitting member is in said second axial position.

Claim 13

Apparatus as claimed in claim 10 wherein said second control lever is non-rotatably mounted on said one motion transmitting member, said one motion transmitting member being movable by said second control lever between said first and second axial positions in response to movement of said second control lever between said second and third control planes, respectively.

Claim 14

Apparatus as claimed in claim 11 wherein said first control lever is non-rotatably mounted in the other of said motion transmitting member to cause rotation of said other motion transmitting member in response to rotation of said first control lever.
