Pittsburgh in 1915, the engine consists of a single double-acting steam cylinder mounted aft of and above the engines, coupled to the rudders, with the motion of travel abeam. The steam valves

Prior to the invention of the steering engine, large steam-powered warships with manual steering needed huge crews to turn the rudder rapidly. The Royal Navy once used 78 men hauling on
