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 The horizontal tubes are staggered and may be withdrawn horizontally by disconnecting them from the two vertical tubes at front and back.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."}, {"label": "Description", "content": "Reference:"}, {"label": "Description", "content": "This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A.
