Thanks Larry...but I'm not sure his patents were filed under the actual name "Helice." A number of web sites in France say this. Here is one comment by JP2,
"Pour ma part j'ai bien dit qu'ill ne fallait pas confondre le system "Heliobloc," qui est bien un brevet VC qui est bien enregistrée en tant que telle et la Marque Helice Il est vrai qa'un grand nombre de fabrications se sont prévalue de la "fermeture hélice" qui par ailleurs n'est pas une appellation déposée."
"As for me I have said repeatedly that one must not confuse the system "Helicobloc," which was patented by Verney Carron and registered as such and the (engraved) mark "Helice." It's well known that a great number of gun makers have availed themselves of the (have used the) "closing system 'helice' " which in any event was not a registered name."
VC definitely patented a Helice quadruple lock system. However, per the French web-sites the actual word "helice," was not on the patent which allowed many others to use it in many ways.
