Abstract
Abstract A multiple ratio automatic transmission and a two-speed synchronized transmission are connected in series to provide a wide range of different speed ratios. A motion converter mechanism is used to convert a unidirectional input from a transmission control lever into a first output having cycled rotary motion for changing the automatic transmission operation from drive to neutral and back to drive to allow shifting in manual gear box under no-load conditions. The converter mechanism includes a second output which changes the manual gear ratio when the automatic transmission is in a neutral operating condition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
In a control for first and second power transmission units operatively connected in series and with said first transmission unit having a forward drive and neutral operation and said second transmission unit having at least two forward drive gear ratios, a movable control member for said transmission units having at least first and second operating positions, actuator means operatively connecting said control member and said second transmission unit so that movement of said control member from either one of said positions to the other one of said positions will actuate said actuator means to effect a gear ratio change in said second transmission unit, and a motion converter mechanism comprising first and second members operatively connected for simultaneous movement together and actuated by said movable control member for mechanically connecting said control member and said first transmission unit for changing said first transmission unit from forward drive operation to neutral operation and back to forward drive operation in response to the movement of said control member from one of said positions to the other so that the gear ratios in the second transmission are changed while said first transmission unit is in a neutral operation condition.
Claim 2
Dependent Claim
196 words
In a control for first and second power transmission units operatively connected in series and with said first transmission unit having a forward drive and neutral operation and said second transmission unit having at least two forward drive gear ratios, a movable control member for said transmission units having at least first and second operating positions, actuator means operatively connecting said control member and said second transmission unit so that movement of said control member from either one of said positions to the other one of said positions will actuate said actuator means to effect a gear ratio change in said second transmission unit, and a motion converter mechanism comprising first and second members operatively connected for simultaneous movement together and actuated by said movable control member for mechanically connecting said control member and said first transmission unit for changing said first transmission unit from forward drive operation to neutral operation and back to forward drive operation in response to the movement of said control member from one of said positions to the other so that the gear ratios in the second transmission are changed while said first transmission unit is in a neutral operation condition.
Claim 3
Dependent Claim
140 words
The control defined in claim 1 wherein said motion converter mechanism comprises first and second cam members, support means for said cam members, pivot means pivotally mounting said cam members on said support means, each of said cam members having a cam surface thereon, coupling means operatively connecting said cam members so that one of said cam members moves in response to the movement of the other of said cam members, and cam actuator means operatively connected to said control member for contacting said cam members and being movable across said cam surface of one of said cam members to effect the rotation of both of said cam members in one direction and subsequently movable across said cam surface of the other of the cam members to effect the rotation of both of said cam members in an opposite direction.
Claim 4
Dependent Claim
133 words

Claim 5
Dependent Claim
47 words
The control defined in claim 3 and further comprising a transmission operator member for said first transmission unit and secured to one of said cam members to provide an output having a cycled output motion for conditioning said first transmission unit for neutral and drive range operation.
