Abstract
Abstract A manual shift handle for a vehicle transmission is pivotally mounted on the steering column and extends to the left side thereof for operation by the left hand of the operator. This arrangement frees the operator''s right hand for manipulation of hydraulic valve levers and the like. Fore and aft pivotal movement of the left hand shift handle will select the same transmission speeds or directions as would be selected by corresponding fore and aft movement of a standard right hand lever installed on the transmission control rod. This is achieved by a motion reversing mechanism between the left hand shift handle and the transmission control rod.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
A steering column transmission control mechanism for a motor vehicle comprising: a steering shaft a fixed support for said steering shaft, a transmission control rod rotatably mounted on said support alongside said steering shaft and adapted for connection to a manual transmission control lever extending laterally therefrom at one transverse side of said support, a manual transmission shift control handle pivotally connected to said support and extending laterally outward at the other transverse side of said support, and pivotal motion reversing means interconnecting said control handle and said control rod.
Claim 2
Dependent Claim
90 words
A steering column transmission control mechanism for a motor vehicle comprising: a steering shaft a fixed support for said steering shaft, a transmission control rod rotatably mounted on said support alongside said steering shaft and adapted for connection to a manual transmission control lever extending laterally therefrom at one transverse side of said support, a manual transmission shift control handle pivotally connected to said support and extending laterally outward at the other transverse side of said support, and pivotal motion reversing means interconnecting said control handle and said control rod.
Claim 3
Dependent Claim
75 words
The invention of claim 1 wherein said pivotal motion reversing means includes a first part rigidly secured to said handle and extending toward said control rod and a second part rigidly secured to said control rod and extending toward said handle, said first and second parts having intermeshing ends thereon operable to cause said control rod to pivot in one direction of rotation on pivotal movement of said handle in the opposite direction of rotation.
Claim 4
Dependent Claim
34 words
The invention of claim 2 wherein one of said intermeshing ends presents a groove and the other of said intermeshing ends presents a tongue extending into and in motion transmitting engagement with said groove.
