in which a member of uniform effective diameter mounted on a shaft may co-operate with different parts of another member

Full Title

Gearings for conveying rotary motion with variable gear ratio, or for reversing rotary motion, by friction between rotary members (control of change-speed or reversing-gearings conveying rotary motion F16H59/00 - F16H63/00) > with members having orbital motion > Gearings providing a continuous range of gear ratios > in which a member of uniform effective diameter mounted on a shaft may co-operate with different parts of another member
