SALMSON 9Z French WW1 Radial Engine - Unique!

[xylstra]

I am trying to obtain the patent of the wholly unique WW1-era SALMSON 9Z water-cooled radial engine which employed a novel 'true-motion' geared crankshaft system made to patents assigned to the Swiss inventor's Canton and Unne. I am informed that this patent dates to 1909. Can anyone adept with the patent search system locate it and provide a link? Many thanks!

... the term "Salmson 9Z patent" with my search engine(s) and got this result:

Maybe it will be useful for you, since at least time and date of the patent application are mentioned (France, 15-12-1908).

Have fun...

Hi Volker, thanks for the reply but I've already seen that. The patent number remains elusive but it will probably be embossed on the maker's plate attached to an original engine in a museum somewhere Maybe someone can check?

Not a link to the actual patent, but an example for the use of Google Patent Search with generally sensible parameters ... in the hope that's of any use to you:
