Can't find the parent patent anywhere. But like his other patents, it cites a supposed parent patent from 1912-02-24, and this time it's explicitly a Danish one.
- January written Jänner here, not Januar as is now common/standard in German
- I am pretty sure this is basically a helicopter, although I can't find it written that way in the patent text. But the diagrams are pretty clear on this, and the histories jibe with that, e.g. on Danish wikipedia
