In 1836, Connecticut-born Colt received a U.S. patent for a revolver mechanism which enabled a gun to be fired multiple times without reloading. Sales were initially slow and his business ventures struggled. Then the U.S. government ordered 1,000 Colt revolvers in 1846, with the Mexican–American War under way. In 1848, Colt was able to start again with a new business of his own, and he converted it into a corporation in 1855 under the name of Colt's Patent Fire Arms Manufacturing Company. The original factory is situated in the Sheldon/Charter Oak neighborhood just south of downtown Hartford.
