content: Ericsson’s improvement in the construction of ordnance was one of many inventive achievements, including the design for the battleship U.S.S. Monitor during the American Civil War. In 1863 he was granted a patent for this improved gun carriage. It allowed the cannon to recoil backward in its tracks when fired and was made to be worked by fewer hands within a confined space such as a gun turret.
