label: Description
content: The engine is designed primarily for boat propulsion and permits the use of a horizontal steam cylinder installed low within the boat in combination with a beam working vertically as in a beam engine.
label: Description
content: The model is diagrammatic in form, is made of wood, and is not complete. The engine represented is essentially a beam engine laid upon its side so that the cylinder is horizontal and the beam is supported vertically. The patent drawing shows the cylinder placed directly upon the keelson of a boat with the beam held so that the lower end is at the approximate level of the center of the cylinder. A long connecting rod attached to the upper end of the beam reaches back over the cylinder to a crank on the engine shaft, which is located above the cylinder and back of it.
