Claim 1
Independent Claim
352 words
A shift mechanism for controlling a multiple speed transmission comprising: a torque input shaft; a first countershaft; a second countershaft; gearing defining multiple torque delivery paths including multiple pairs of gears carried by said 75 input shaft and said first and second countershafts; synchronizer clutch means associated with one gear of each pair for driveably connecting said one gear to its associated shaft a differential gear assembly; torque output gearing connecting said differential gear assembly with said first and second countershafts whereby torque is delivered from said gearing to said differential assembly; a first shift rail and a second shift rail each mounted in parallel disposition with respect to said input shaft and said first and second countershafts; first and second shift forks mounted slidably on 90 said first shift rail, and a third shift fork mounted slidably on said second shift rail for moving the synchronizer clutch means thereby driveably connecting one gear of each gear pair to its associated shaft, one of said shift forks being engageable with the reverse gear on said first countershaft; and a linkage mechanism for effecting shifting movement of said first, second and third shift forks including: a shift selector shaft adapted for rotary and axial movement mounted in transverse disposition with respect to said first shift rail; a relay lever mounted for rotation and sliding motion in transverse disposition with respect to said shift selector shaft having first and second operating arms engaged respectively with said shift selector shaft and said first shift rail whereby axial movement of said selector shaft produces axial movement of said first shift rail and rotary motion of said selector shaft produces rotary motion of said first shift rail; a bellcrank pivotably mounted in transverse disposition with respect to said first shift rail having a first end engaged with said third shift fork; and selector means mounted on said first shift rail adapted to rotate into registry selectively with the second end of said bellcrank and the first and second shift forks; whereby axial movement of said first shift rail produces axial shifting movement of said synchronizer clutch means.

Claim 3
Dependent Claim
134 words
The shift mechanism according to Claim 1 further comprising: a reverse drive pinion mounted for movement into and out of engagement with the reverse drive gears on said input shaft and said first countershaft; a second bellcrank pivotably mounted having a first end disposed adjacent said first shift rail and a second end engaged with and adapted to move said reverse pinion; and a shift collar secured to said first shift rail engaged with the second operating arm of said relay lever having an operating arm adapted to engage the first end of said second bellcrank; whereby, upon engagement of said second bellcrank by said shift collar, axial motion of said selector shaft causes said reverse pinion to produce a driving engagement between said reverse gears on said input shaft and said first countershaft.
Claim 4
Dependent Claim
90 words
The shift mechanism according to Claim 2 further comprising a shift interlock collar slidably mounted on said first shift rail adapted for rotary motion as said first shift rail rotates but prevented from axial motion including: a slot permitting said selector means to move therethrough as said first shift rail moves; and blocking means engageable with two elements of the group consisting of the second and of said first bellcrank, said first shift fork and said second shift fork when said selector means engages the other element of the group.
Claim 5
Dependent Claim
161 words
An interlock shift mechanism for controlling the shifting motion of first and second shift forks mounted on a first shift rail and a third shift fork mounted on a second shift rail comprising: a pivotably mounted bellcrank having a first end engaged with said third shift fork and a second end disposed adjacent the first shift rail; selector means secured to the first shift rail adapted to selectively engage the first and second shift forks and the second end of said bellcrank; a shift interlock collar slidably mounted on said first shift rail adapted for rotary motion as the first shift rail rotates but prevented from axial motion; a slot permitting said selector means to move therethrough as the first shift rail moves; and blocking means engageable with two elements of the group consisting of the second end of said bellcrank, the first shift fork and the second shift fork when said selector means engages the other element of the group.
Claim 6
Dependent Claim

An interlock shift mechanism for controlling the shifting motion of first and second shift forks mounted on a first shift rail and a third shift fork mounted on a second shift rail comprising: a pivotably mounted bellcrank having a first end engaged with said third shift fork and a second end disposed adjacent the first shift rail; selector means secured to the first shift rail adapted to selectively engage the first and second shift forks and the second end of said bellcrank; a shift interlock collar slidably mounted on said first shift rail adapted for rotary motion as the first shift rail rotates but prevented from axial motion; a slot permitting said selector means to move therethrough as the first shift rail moves; and blocking means engageable with two elements of the group consisting of the second end of said bellcrank, the first shift fork and the second shift fork when said selector means engages the other element of the group.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
