Propeller in tube ("casing"), possibly with rudders/elevators/airfoils attached. Discussion of center of wind pressure and center of gravity; I didn't follow. Seems to focus on dirigible airships, but not to have excluded application on airplanes.
- Inventor location: Milwaukee, Milwaukee county, WI (FIPSloc=55079, imputed by HistPat)
- Tech class CPC B64C30/00 Supersonic-type aircraft Misclassified as [[{{{1}}}]]?
- dates are confusing. Spec dated 1907, filed Aug 1908, granted in 1913 -- no, that's an earlier patent, Patent US-1907-1072663. espacenet's pdf is messed up; it has a page of the earlier one as the first page here. let's look at USPTO's copy.
