Patent BE-1909-219377 RdBdI

"Cette machine volante se compose de deux grandes ailes circulaires ou roues se mouvant sur un même axe vertical, mais en sense contraire."

That is, "This flying machine is composed of two large circular wings, or wheels, moving on one single vertical axis, but in opposite rotational directions".

(This may have more to do with ascension than with propulsion, and this may be some sort of precursor to the helicopter. These "wings", in fact, may be a grand form of propeller.)

We don't see the text of this patent, but we see foreign filings of it.

Inference: this inventor listed as A. Beurrier in sources must be Alexis Beurrier who has many other patents.

  • Inventor location: Montguyon, France
