A flying machine with series of blades revolving around a transmission shaft ; but doesn't use words like helicopter or propeller. Why not? The device seems mechanically complicated ; there seem to be wheels rotating around the spokes and endpoints of the main wheel/impeller. He refers to planetary gears. Not clear if this rotating assemblage is for horizontal propulsion, vertical lift, or both, although it seems designed to be flexible with multiple kinds of pivot and flexibility.

- Inventor location: Citizen of the Swiss Republic, located at NYC, New York county, NY (FIPSloc=36061, imputed by HistPat)
