As fine as this patent Diagram 1 may be, featuring an entire aircraft, we believe that at least the emphasis is on propellers applicable to multiple aircraft types.
This is equal to Patent FR-1909-403665, which has an analogous offshoot pattern within the French system, as does Patent GB-1909-13791 within the British.

- “Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én (or án)”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know which legally constitutes the patent’s being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.
