label: Description
content: The model represents a sectional marine water-tube boiler in which the proportions of the elements and the manner of their connections are designed by the inventor to facilitate the removal of tubes or sections within a relatively small space.
label: Description
content: The boiler is constructed of sections, each of which consists of a vertical tube at the back of the boiler from which projects a vertical row of horizontal tubes. Each horizontal tube is closed at the front end with a screw plug through which a short central tube connects to a small vertical tube, common to all the horizontal tubes of a vertical row. These vertical tubes at the front are closed at the bottom end and are joined by a transverse steam pipe at the top. The horizontal tubes are staggered and may be withdrawn horizontally by disconnecting them from the two vertical tubes at front and back. Each horizontal tube has an internal tube designed to improve the circulation. The back vertical tubes are flat sided and placed together to form the back of the boiler. The horizontal tubes in the outside sections are assembled close together to form the sides of the boiler.
