William Mont Storm Engine, Patent Model

This model formed part of the application to the U.S. Patent Office for the patent issued to William Mont Storm on July 11, 1865, no. 48777.
This is a 3-cylinder engine of a radial type, designed to produce rotary motion with compactness and simplicity.
The engine consists of two horizontal, opposed, single-acting cylinders and one vertical double-acting cylinder. The pistons of the horizontal cylinders are extended and joined to form a slotted crosshead in which one crank of the crankshaft moves. The piston in the vertical cylinder has a much shorter stroke and the piston rod from it extends to a second cross head and crank. D-slide valves are operated by a very small crank at the end of the crankshaft, in a valve chest located at the center of the engine. The engine is reversible.
This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A. Taylor.
