Engineering, Building, and Architecture - Overview

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.

E. Howard and Company Tower Clock
- Description
- In places that required many clocks—factories, office and public buildings, or schools—time was often distributed by a system of "master" and "slave" clocks. In such a system, a central timekeeper, the master clock, sent periodic impulses, usually electric or pneumatic, to any number of secondary or slave clocks. These slave clocks could be located anywhere, without regard for convenience of winding, because they needed none. The master clock could also drive other time signals like classroom bells, factory whistles, or time stamps. More economical to install and more convenient to maintain than an equal number of independent clocks, the system also ensured that all dials within the system agreed.
- The museum collection contains such a timekeeping system. The system's master clock (Cat. 310,569), built by E. Howard and Company of Boston, is a mechanical tower clock movement equipped with electrical contacts. Once a minute the escapement, through a pair of rotary switches, closes an electrical circuit and sends an impulse to the slave dial (Cat. 310,570), where electromagnets advance the hands. Batteries at the base of the master clock supply current.
- This clock and dial were components of a system that served the Smithsonian between about 1881 and 1932. First housed in the north tower of the Arts and Industries Building, the clock movement distributed impulses to eighteen dials in that building and the Castle, the Smithsonian's earliest building. Tunnels under the floors carried the wiring. The clock room also housed a telephone switchboard, a watchman's clock, a central burglar alarm, and call bells—all of which, like the time distribution system, relied on the newly harnessed power of electricity. "Indeed," boasted the Smithsonian's annual report for 1881, "it is believed that in no building in the world, with the exception of the Grand Opera House in Paris, is there so perfect and complete an application of electricity to practical services."

Post Instruction Manual for Versalog Slide Rule
- Description
- This is a later printing of 1978.0800.02. Its citation information is: E. I. Fiesenheiser, Versalog Slide Rule Instruction Manual, with R. A. Budenholzer and B. A. Fisher (Chicago: Frederick Post Company, 1963). The text appears not to have been revised since these three Illinois Institute of Technology engineering professors helped invent the Versalog slide rule and wrote instructions for using it in 1951. Marks inside the front cover indicate this copy was offered for sale in January 1969 for $1.00.

Cladding Fragment from the World Trade Center
- Description
- This crumpled piece of exterior sheathing was recovered from the debris pile of the World Trade Center after the building collapsed following the terrorist attacks of September 11, 2001. While the towers withstood the initial damage caused by the impact of the hijacked jet liners being crashed into the structures, the intense fire that then raged proved to be too much.
- The twin towers of the World Trade Center, a New York City landmark and the tallest buildings in the world when completed in 1973, were noted for their incredible 110-story height and their gleaming exterior. The towers were clad in an aluminum alloy sheathing that gave the buildings a golden sheen at sunrise and sunset. The material covered the closely-spaced exterior steel columns, enhancing their soaring appearance. Architect Minoru Yamasaki choose to use an aluminum alloy after first considering the more expensive alternative of stainless steel. The highly reflective sheathing of the twin towers added to the building's impact as a memorable landmark.

Lyman Protracting Trigonometer Signed Heller & Brightly
- Description
- This metal drawing instrument allows civil engineers to translate their measurements into drawings with a minimum of calculation. It consists of a flat steel base bar 81.5 cm (about 32 inches) long, a semicircular protractor with a flat plate along the diameter that slides along the base bar, a long steel arm clamped to the protractor at its center, a brass set square or sliding square that moves along the arm, and a tri-leaved scale (like an architect’s scale) that moves along the arm or along the set square. There are four metal springs, each with its own screw. The two smaller springs hold the protractor plate to the base bar and the two larger ones hold the tri-leaved scale or the set square to the arm. The entire instrument fits in a wooden case. A sheet of instructions is pasted inside the case.
- The protractor is divided by half-degrees and marked by tens from 0° to 90° to 0° and from 90° to 0° to 90°. An attached vernier permits angle readings to one minute of arc. The ratios on the architect's scales range from 1:10 to 1:60. Each scale is divided into tenths of a unit.
- This is a modified form of the protracting trigonometer patented by Josiah Lyman of Lenox, Mass., in 1858, with reissue of the patent in 1860, and extension in 1872 (for an example of the protracting trigonometer, see MA*328738; for an architect’s rule patented by Lyman, see MA*308914). The instrument was made by Heller & Brightly of Philadelphia. According to a Heller & Brightly circular, the instrument sold with either a tri-leaved scale that was 6 inches long or one that was 12 inches long. This instrument has the 12-inch scale, and would have sold in 1878 for $30.00.
- Hobart Cutler Dickinson (1875–1949), a 1900 graduate of Williams College who obtained a master’s degree there and did further graduate work at Clark University (Ph.D. 1910), owned this object. Dickinson worked at the U.S. National Bureau of Standards from 1903 until his retirement in 1945. Dickinson was the father of Anne D. Ross, one of the donors of the instrument.

Hart House Architectual Elements from Ipswich, Mass.
- Description
- The largest artifact in the museum, this Georgian-style, 2 ½-story timber-framed house was built in the 1760s and stood at 16 Elm Street in the center of Ipswich, Massachusetts, until 1963 when efforts by Ipswich citizens saved it from the bulldozer. The house was carefully taken apart—the frame, chimney, and many other pieces were shipped to the Museum and reassembled.
- Today, the house is the centerpiece of the exhibition Within These Walls , and visitors are able to peer through its walls, windows, and doors to view settings played out against the backdrop of Colonial America, the American Revolution, the abolitionist movement, the industrial era, and World War II. The exhibition tells the story of five ordinary families, selected from many, who lived in this house over 200 years and made history in their kitchens and parlors, through everyday choices and personal acts of courage and sacrifice.

Child's Tool Chest
- Description
- As illustrated in this child's tool chest from around 1900, children in the early 20th century encountered their society's gender expectations at a young age. The tool chest from R. Bliss & Co. declared carpentry to be boys' work. It came with a hinged lid and a sliding, removable top tray. Inside is a colored picture of boys building a house under a banner that reads "BLISS UNION TOOL CHESTS FOR BOYS." R. Bliss & Co., established in 1845, started as a tool company, making wooden screws and clamps for piano and cabinetmakers, before it became a leading manufacturer of toys by the turn of the 20th century.

Knox Hydraulic Pump Slide Rule
- Description
- This rule consists of a clear plastic envelope, glued together along the back bottom edge, and a white plastic slide. The front is marked: KNOX (/) SO. WALPOLE/W. SPRINGFIELD. MASS./BRIDGEPORT, CONN. (/) PNEUMATIC & (/) HYDRAULIC SYSTEMS & (/) COMPONENTS. By setting the force in pounds opposite the PSI of a line, a user can read the diameter of a cylinder in inches. By setting the rule to the desired diameter of a cylinder, the user reads the displacement in cubic inches opposite the length of a stroke in inches. By setting the back of the rule to a desired pump delivery in gallons per minute, the user reads the time in seconds opposite displacement in cubic inches and the velocity of oil flowing through the pipe (in feet per second) opposite the area of the pipe in square inches.
- Knox, Inc., manufactured hydraulic pumps. From its headquarters on Foxhill Drive in South Walpole, Mass., the company filed for trademarks in 1966 and 1968 and was assigned U.S. Patent 3,599,849 in 1971. Thus, this rule likely dates to around 1970. By 1980, the company was renamed Knox-Norton, Inc., and headquartered in Hartford, Conn.

Ford Coupe Stock Car, 1952
- Description
- In 1952, Leon Hurd extensively modified this 1932 Ford coupe, beefing-up the frame and installing stronger springs, and installing a 1942 Ford "59A"-block "flathead" V-8 engine. Initially the car ran without fenders, during the short time that was permitted by the Atlantic Racing Association racing rules. (NASCAR was in its infancy.)
- Hurd raced in New England from 1952 through 1955, winning more than 100 races in that time. The car carried racing number "00." In 1979, Hurd did some minor restoration on the car.World War II period saw a relative explosion of motor racing on both sides of the Atlantic and a proliferation of distinctly American types of racing with no counterparts in Europe. One such uniquely American type was "stock car" racing. Popular interest was whetted by races run with cars that were entirely like - or mostly looked like - those for sale in the showrooms or on the used-car lots. Fans could cheer for cars that looked like the cars they drove in everyday use.
- Most auto racers preferred two-door coupes: a smaller, two-door car was lighter for better acceleration yet could house a powerful engine; and a coupe had a roof, which helped protect the driver in roll-overs, which were not uncommon in the pell-mell anarchy of beach races. To help him set rules for stock-car racing, Bill France created the National Association for Stock Car Auto Racing, NASCAR, in 1948; NASCAR's first season was 1949. Then France had another idea: too many spectators could enjoy his beach races without paying the admission charges for his viewing areas closer to the course. So why not build a modern oval race track away from the beach, surrounded by bleachers, and thus configured so that any and all spectators had to pay to see the races - and far more spectators at that?
- It was an old idea, actually. In the US from about 1910, the dominant money in the early years of auto racing came from entrepreneurial track owners (many of whom had previously owned bicycle tracks or velodromes). Track owners knew that strict control of access to the racing venues was the key to maximum income from spectators. And oval tracks gave by far the best view to the most customers, also a motivating factor for ticket buyers. (In contrast, Europe and Britain never developed such enclosed oval tracks. Very wealthy car-owners and manufacturers have always controlled auto racing there, and such elite car-owners and manufacturers have strongly preferred open-road courses as more sporting - and also more likely to help improve auto design technology. Thus modern European closed tracks still follow the "open road" idea, with lots of turns and curves.)
- Bill France saw the success of the paved oval track built at Darlington, SC, in 1950. So, with his business model in hand based on droves of paying race fans, France began raising money in 1953 and, a few years later, opened a new Daytona Speedway. NASCAR came of age in 1959, with the first running of the Daytona 500.
- "Stock-car" racing found a home quickly in the South, where "moonshiners" or "rum runners" during Prohibition had been modifying ordinary-looking cars with "souped-up" engines (i.e., modified for greater power) and stiffened suspensions -- and hidden tanks for booze -- to outrun federal marshals on backwoods roads when necessary to elude arrest. But organized stock-car racing on closed courses -- beginning in the late 1940s -- found eager fans as well in the Northeast, Midwest, and Far West; the South had no monopoly. Sponsorship money, particularly from local auto dealers, became more plentiful; "win on Sunday, sell on Monday" soon became a byword among retail car dealers. The cheaper, individually owned stock cars -- coupes that were often referred to as "jalopies" -- raced on local and regional dirt tracks. Well-sponsored cars fielded by wealthier owners with funding and engineering assistance from Detroit manufacturers raced at larger, paved oval tracks with extensive bleachers for the fans.
- Track owners set the pattern for organized stock-car racing. Bill France, of Daytona Beach, Florida, had witnessed the popularity of pre-war "beach racing" (see Web entry on the racing automobile, Winton 'Bullet' No. 1). In the late 1940s, he organized beach races for any local car-owners who liked the idea of competing against each other with more-or-less "stock" automobiles.

Keuffel & Esser 4088-5 Polyphase Duplex Slide Rule
- Description
- This duplex linear slide rule is made of mahogany coated with celluloid. There are DF and D scales on one side of the base and K, A, D, and L scales on the other side. There are CF, CIF, and C scales on one side of the runner and B, S, T, and CI scales on the other side. The scales are 20 inches long (the "5" in the model number refers to a rule with scales 20 inches long) and closely divided. The indicator is made of glass with a plastic frame.
- The base is marked: KEUFFEL & ESSER CO.N.Y.; PAT. JUNE 5. ’00; DEC. 22. ’08; MADE IN U.S.A. The runner is marked: 4088-5. The serial number, on the other side of the runner, is: 72287. The slide rule is stored in a dark brown cardboard and glued leather box.
- Keuffel & Esser published catalogs in 1899, 1902, 1905, 1909, 1912, 1915, 1921, 1927, and 1936. Model 4088-2 (8 in.) and 4088-3 (10 in.) slide rules first appeared in the 1913 printing of the 1912 catalog (facing p. 304). Model 4088-5 was first mentioned in 1921 (p. 239) and then again in 1927 (p. 302). In 1927 and in the 1930s (but not in 1921), the front of the runner had a B scale in addition to the S, T, and CI scales. By 1936, the 4088-5 was replaced by the N4088-5 (p. 314). On this basis, the rule dates from between 1922 and 1935. Additionally, the donor reported that he received the slide rule from a friend in about 1930. The instrument sold for $20.00 in 1927. Compare this object to MA*318476 and 1986.0790.02.
