This is an addition to Patent FR-1915-502520, which brevet was filed 1915-11-06.
- Inventor locations: Alexis Beurrier was located within département Charente-Inférieure, now département Charente-Maritime, France, Edmond Bigourdan was located within département Seine-et-Oise and Louis Lacoin was located within département Seine.
- It's tricky to figure out whether Edmond Bigourdan is the same as Edouard Bigourdan or not. They are both listed as patenting with Beurrier, as well as with Lacoin, but not with one another. We are leaning to an extreme likelihood that this Edmond Bigourdan is Édouard-Jean Bigourdan.
