Patent ID: 8763481

Claim:
A transmission for a lever-powered vehicle, comprising: a. a right crank; b. a left crank; c. a rotating shaft; d. a left one-way clutch, said left one-way clutch locking said left crank to said rotating shaft when said left crank is rotated in a counter-clockwise direction, and unlocking when said left crank is rotated in a clockwise direction; e. a right one-way clutch, said right one-way clutch locking said right crank to said rotating shaft when said right crank is rotated in a counter-clockwise direction, and unlocking when said right crank is rotated in a clockwise direction; f. a right ring gear attached to said right crank; g. a left ring gear attached to said left crank; and h. a plurality of reversing gears continuously meshing with said right ring gear and said left ring gear, whereby said plurality of reversing gears force said right and left ring gears to rotate in opposite directions so that torque applied to said right crank at a time said right one-way clutch is in an unlocked state will be transferred through said reversing gears to said left ring gear, and thence through said left one-way clutch to said rotating shaft.
