Description: |
| Abstract:
While hydraulic controls of various types have heretofore been applied to a variable speed transmission of the Reeves type, it is the primary object of the present invention to provide a hydraulic control of a sort which has not heretofore been adapted to such a use, and to associate such a control in a novel manner with the shiftable elements of the transmission, thereby providing a combination which, while very simple, achieves an accuracy and delicacy of control not heretofore obtainable with such simple mechanism.
Claim:
For use with a variable speed transmission having two .levers oppositely movable simultaneously to effect variations in the speed ratio of said transmission, and means operatively connected with said levers to enforce such opposite simultaneity of movement, a fluid motor comprising a cylinder supported upon and movable with one of said levers, a piston reciprocally received in said cylinder and having an operative connection with the other of said levers, a source of fluid under pressure, and means for controlling fluid flow to and from opposite ends of said cylinder. |
