Model of an American Marine Beam Engine, 1887

This model made by Max Zwickel of Jersey City, New Jersey, in 1887 represents a typical walking-beam engine used on Hudson River steamboats of that time. "Walking beam" refers to the prominent diamond-shaped rocker arm on top that helped convert the up-and-down motion of the piston into the rotary motion of the flywheel. It took Zwickel five years to complete the model.
