The Improved Greene Engine, circa 1871
- Greene Steam Engine, circa 1880 - Noble Greene designed this engine with an automatic cut-off valve that improved speed control. Greene invented this mechanism in 1855, but could not sell it because of a patent battle with George Corliss. The courts sided with Corliss and protected his valve mechanism claims preventing Greene from manufacturing his engine design until Corliss' patent expired in 1870.
