Patent Model for Steering Steam Ships

Mechanical engineer Frederck Sickels devoted his career to improving steam engines and advancing their use at sea. He was particularly interested in developing steam-assisted steering, a topic dear to many inventors as ships became larger and heavier through the middle of the nineteenth century. This patent model demonstrates Sickels's idea for a steering apparatus where steam pressure in a pair of cylinders would both control the side-to-side motion of a vessel's rudder but also hold the rudder stationary against the force of the surrounding water.
