Ritty Steam Boiler, Patent Model

This model was submitted to the U.S. Patent Office with the application for the patent issued to Sebastian Ritty, of Dayton, Ohio, July 22, 1873, no. 141172.
The model represents a horizontal cylindrical flue boiler from the center of which is suspended a rectangular water chamber or header. From the header a series of horizontal closed-end water tubes extend forward and back within the furnace below the drum. The outside ends of the tubes are closed and are supported in sheets, which form the front and back walls of the furnace. The forward lower tubes support the grates, and the products of combustion pass through an opening in the central header around the back tubes up and then forward through the flues of the drum.
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.
