Abstract
Abstract A vertical transmission shift lever of a heavy duty high speed motor truck is provided with a transversely extending rotary handgrip which can be moved orbitally to shift the lever as required, and which can be moved rotationally to push or pull the speed-ratio switch as required. When moved orbitally, the transmission gears are shifted. When moved rotationally, the rear-axle gear-ratio is changed from high to low or vice versa. These movements can be made either contemporaneously or independently.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
200 words
A manually-operated mechanism for contemporaneously and independently shifting the transmission gear lever of and operating a push-pull switch controlling the high-low gear-ratio in the rear axle of a motor truck, comprising: A. a handgrip assembly composed of a stationary base part and a rotary handgrip part; B. means for mounting said stationary base part to the upper end portion of the shift lever of a truck for forward, rearward and lateral shifting movement with that lever; C. means for mounting the rotary handgrip part on the stationary base part in a transversely extending position relative to the upper end of the shift lever so that a truck operator can grasp the handgrip and bodily move it forwardly rearwardly and laterally as required to shift the lever correspondingly, 1. said handgrip part being mounted on the base part for relative forward and rearward rotational movement about a transverse axis through an angle sufficient for push-pull switch-operating purposes; and D. means for connecting the rotary handgrip part to the control switch for the high-low gear-ratio in the rear axle to operate that switch one way when the rotary handgrip part is rotated forwardly and the opposite way when it is rotated rearwardly.
Claim 2
Dependent Claim
200 words
A manually-operated mechanism for contemporaneously and independently shifting the transmission gear lever of and operating a push-pull switch controlling the high-low gear-ratio in the rear axle of a motor truck, comprising: A. a handgrip assembly composed of a stationary base part and a rotary handgrip part; B. means for mounting said stationary base part to the upper end portion of the shift lever of a truck for forward, rearward and lateral shifting movement with that lever; C. means for mounting the rotary handgrip part on the stationary base part in a transversely extending position relative to the upper end of the shift lever so that a truck operator can grasp the handgrip and bodily move it forwardly rearwardly and laterally as required to shift the lever correspondingly, 1. said handgrip part being mounted on the base part for relative forward and rearward rotational movement about a transverse axis through an angle sufficient for push-pull switch-operating purposes; and D. means for connecting the rotary handgrip part to the control switch for the high-low gear-ratio in the rear axle to operate that switch one way when the rotary handgrip part is rotated forwardly and the opposite way when it is rotated rearwardly.

Claim 7
Dependent Claim
20 words
a linkage connecting the outer end portion of the crank arm to a push-pull operating member on the control switch.
Claim 8
Dependent Claim
12 words
The mechanism of claim 2 wherein: A. the handgrip connecting means comprises:
