Crochat and Colardeau

Henry Crochat obtained some patents jointly with Emmanuel Colardeau, e.g. patent US1416611.{{Cite web|url=http://worldwide.espacenet.com/publicationDetails/originalDocument?CC=US&NR=1416611A&KC=A&FT=D&ND=3&date=19220516&DB=worldwide.espacenet.com&locale=en_EP|title=Espacenet - Original document}} There is no evidence that Colardeau was involved in Crochat's railway business but he may have been involved, with Crochat, in the design of the Saint-Chamond (tank).
