Engineering, Building, and Architecture
Not many museums collect houses. The National Museum of American History has four, as well as two outbuildings, 11 rooms, an elevator, many building components, and some architectural elements from the White House. Drafting manuals are supplemented by many prints of buildings and other architectural subjects. The breadth of the museum's collections adds some surprising objects to these holdings, such as fans, purses, handkerchiefs, T-shirts, and other objects bearing images of buildings.
The engineering artifacts document the history of civil and mechanical engineering in the United States. So far, the Museum has declined to collect dams, skyscrapers, and bridges, but these and other important engineering achievements are preserved through blueprints, drawings, models, photographs, sketches, paintings, technical reports, and field notes.
"Engineering, Building, and Architecture - Overview" showing 1 items.
- This model was submitted to the U.S. Patent Office with the application for the patent issued to George H. Babcock, of Plainfield, Hew Jersey, and Stephen Wilcox, of Brooklyn, New York, April 4, 1876, no. 175548.
- The model represents the typical elements of an inclined tube, horizontal longitudinal drum boiler upon which are shown the mode of mounting and supporting such boilers and the provisions for making the connections of the parts that are the subject of the patent.
- The drum of the boiler is represented as having cast-iron ends, each of which is formed with a stout horn near the top adapted to receive a suspension link from a cross girder resting upon columns at the sides of the boiler. Each end casting is further provided with a series of holes near the bottom properly adapted to receive tubes joined thereto by the process known as expanding. These tubes are joined at the front and back to the vertical tubes rising from the water-tube headers by means of hollow castings in which hand holes are provided that permit both sets of tubes to be expanded in the openings in the castings.
- These improvements are said to be the results of the inventors’ experience with the boiler patented by them February 18, 1873, no. 135877.
- 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.
