This is the third addition to Patent FR-1908-401308, which was filed 1908-07-18.
This addition has specifically to do with replacing the propeller described in said parent brevet and in the first two additions.
Also, this patent makes reference to Patent FR-1911-433440, a non-aeronautical patent filed non-collaboratively by Ravelli, using the fuller name Jacques-Jacinthe Ravelli. The alleged final improvement inherent to this addition is the application of automobile shock-absorbers to aeronautical needs, related to landing. So, the collaborative Chevron-Ravelli patent family was furthered and enhanced by the non-aero investigations in which Ravelli was concurrently engaged.
