Description: |
| "My invention consists of a series of planetary gears, each meshing with a ring which is free to turn, or which may be prevented from turning, at will. The particular ring which is prevented from turning determines the speed of the driven member. My mechanism is compact, readily driven by an electric motor which may be so mounted as to form an integral part of the mechanism..." |
