Description: |
| Abstract:
My invention relates to variable-speed and reversing mechanism, and has for its object to provide a simple and efficient driving mechanism for use in connection with motor- vehicles and other machines in which the power, speed, and direction of rotation of the driven member are subject to frequent change, while the energy and speed of the motor-shaft are maintained practically constant, the changes in speed ,and direction in the driven member being effected by differential gearing connecting said member with the motor-shaft and with a speed-varying gearing driven from said motor-shaft.
Claim:
A variable-speed and reversing mechanism, comprising a driving-shaft, a hollow shaft geared thereto, a second shaft upon which said hollow shaft is mounted, a revoluble frame on said second shaft, a differential planetary-gear train connecting said frame with the hollow shaft and with said second shaft respectively, a gear from which power is taken connected to said casing, and means operated from said driving-shaft for varying the speed of said second shaft, whereby the frame and power-gear may be driven in either direction and at a variable speed. |
