The Engine
After Robert Fulton proved the viability of using steam to power a nautical vessel with his steamboat Clermont (also known as the North River) in 1807, steam power began to sweep wind-powered vessels from the seas. Constant improvements to his engine were made and Maudslay's Paddle Engine patented in 1827 was one such improvement. It was a style of engine that used improved valve chests and gear and these so called Penn Oscillating engines were in use for many years. (I hope somebody understood all that as I didn't.) The largest such engines were fitted into the paddle wheeler Great Eastern designed by Isambard Brunel. However, the engines could not be adapted to the higher steam pressures that were being introduced and the paddle engine gave way to the inclined direct-acting engine.
