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.

Corvette ZR-1 racing sports car, 1990
- Description
- Few private owners, and only extremely wealthy ones, campaigned cars in the top sports car races in Europe. As a result of the European influences toward more specialized engineering for the best sports cars, the "prototype" racing classes emerged in the US for the fastest, most powerful US and European-built sports cars - none of which were street legal by any stretch.
- In this context, professional sports car racing became more popular by the 1970s. Later, organizations such as the International Motor Sports Association (IMSA) organized professional races for prototype sports cars and high-powered "GT" sports coupes.
- The Corvette ZR-1 No. 92 was built specially by Tommy Morrison Motorsports in 1990 for racing in the IMSA "GTO" class. General Motors provided backing and technical services; the major financial sponsors were Mobil Oil and EDS. The car is one of several built "from the ground up" as race cars. The tubular space frame resembles that of a modern NASCAR racer; the body follows the Corvette ZR-1's lines exactly but was designed to fit the custom-built frame. The modified Chevrolet V-8 engine was developed by the Mercruiser Corp. The all-independent suspension is that of a production ZR-1 Corvette, with special springing and shock absorbers for racing.
- No. 92 placed 4th in class in the 1991 Daytona 24-hour endurance race, on Daytona's "road course" that uses multiple corners on the big track's infield combined with part of the high banking used by NASCAR racers. The 92 also placed 6th in class in the 1991 Sebring 12-hour endurance race, held at the historic sports car track in Sebring, FL, that still uses a portion of a World War II-era concrete airfield in its circuitous course. Even finishing these endurance races is an accomplishment, and 4th and 6th places, out of the large fields of competing cars, are regarded as highly successful.
- Another of Morrison's ZR-1's set the world speed record for a 24-hour run, averaging some 174 mph.
- Sports-car racing was a post-World War II phenomenon in the US. While racing by stock cars, sprint cars, and dragsters attracted fans of generally middle-class and more modest means, sports-car racing attracted young car-owners and fans primarily of wealthier means. This relationship stemmed from the pronounced cachet that went with European automotive engineering from the late 1930s through the 1960s.
- Ex-servicemen who had been based in England began bringing British sports cars to American soil in 1948. Auto dealerships selling such makes as MG, Triumph, and Jaguar - and Porsche from Germany and Alfa-Romeo from Italy - opened in the US for the first time. These cars were typical of European engineering for two-door performance cars: light, agile, many with small or medium-sized engines compared to general US custom, and right at home on curving, twisting roads where a driver could test his or her cornering skill. Many sports cars were relatively small (by American passenger-car standards) two-door convertibles, and a few were low-slung, two-door coupes. Organized racing for sports cars sprang up immediately. Since no oval track could bring out the qualities of sports-car agility, local organizers often marked out multi-cornered courses with rubber cones and hay bales on the abundant pavements of abandoned military airfields. Organized races through city streets were sometimes approved by local officials.
- Soon enough, paved race tracks—with hilly, twisting layouts emulating courses in continental Europe for "Formula" and sports cars—began appearing in the US. And variations on sports-car racing also quickly took root: endurance races (of two, six, 12, and 24 hours), together with numerous classes (so that less-powerful MGs and Triumphs, for example, could race in different classes than, say, Jaguars, Ferraris, or Maserattis). And "autocrossing" was organized locally in towns all over the US—wherein one car at a time competed for the shortest elapsed time over short, twisting courses often marked off temporarily on large, open macadam parking lots.
- Before long, America got its first sports car: the Chevrolet Corvette, introduced tentatively in 1953. By the late 1950s, a re-engineered Corvette took its place as a competitive sports car, both in the showrooms and on sport-car race tracks.
- The Sports Car Club of America (SCCA) organized sports car races in the US and also licensed amateur drivers, after an on-track skills test with a well-experienced driver. Regional championships were competed-for in many classes, including hand-built sports cars intended only for the track. Through about 1960, a top amateur competitor could file an entry and drive his production sports car to a sports car race, tape-up the headlights (to keep broken glass from flying too far in an incident), remove a few excess parts such as mufflers and bumpers, paint-on an assigned race number to the car temporarily, and go racing. By the early 1960s, such a cavalier approach became passé, and serious sports-car racers prepared their cars as fully as stock-car and sprint-car owners. The SCCA responded to the change by loosening the design rules for its "production" classes to include a variety of engine and other performance modifications - although the car still had to be "street legal," meaning it still had to comply, off the track, with passenger vehicle licensing requirements for use on public roads. The SCCA "modified" classes became more so, including exotic cars intended only for the most serious racing.
- Europeans, meanwhile, developed sports car racing after World War II to a level of sophistication in cars and organization of races almost equal to that of Formula 1 "Grand Prix" racing. And in both types of racing, factory teams were by far the majority of participants.

Racing Go-Kart
- Description
- A truly "grass roots" sport, organized "go-karting" arose in the late 1950s. In the 1930s and late 1940s, various types of smaller open-wheeled race cars had been developed for certain classes of organized racing on oval tracks, including the "midget racers" - diminutive but full-fledged, single-seat, high-speed cars. But for would-be racers of limited means in the 1950s, even these midget race cars were out of financial reach. Meanwhile, marketers of leisure-time products had started producing small, motorized "karts" for pre-teens. Such a kart, intended for driving on paved surfaces off the public roadways, had a light frame made of tubular steel, no "body" at all, a rudimentary open seat, and was equipped with a small gasoline engine mounted behind the driver and tiny tires. Adults thought up the idea of installing more-powerful motors, and the racing "go-kart" was born. Racing of such karts by kids was soon organized -- but racing classes for adults were created as well. Such races were sometimes held at regular paved race tracks but were usually run on specialized, short paved courses designed and built expressly for the karts. In the early days, races ran on large parking lots, with courses marked off for the day with stripes and rubber cones.
- Many racing drivers who became well known in the 1970s, '80s, and through the present -- such as NASCAR's Jeff Gordon, 'Indy 500' drivers Al Unser, Jr. and Michael Andretti, and European 'Formula-1' drivers -- learned their early skills by becoming champion kart drivers in the classes for pre-teens.
- Elwood "Pappy" Hampton (1909-1980), however, was one of thousands who took to the sport as adults. He was a Washington, DC, machinist who became interested in go-kart racing as a hobby. He built several karts, each time refining their design and improving their performance.
- This kart is one made about 1960, which Hampton raced frequently from 1960 through 1962 to first-, second-, and third-place finishes, mostly at the Marlboro Speedway in Maryland. In 1962, he won the East Coast Championship. At age 51 in 1960, "Pappy" was one of the oldest successful kart racers in the mid-Atlantic area, hence his nickname.
- The kart has a duralumin chassis (duralumin for strength with extreme lightness) made especially for racing karts by Jim Rathmann of Indianapolis (the winning driver in the 1960 Indianapolis 500), and a drive train engineered and made by Hampton. The engine is one made in England, fueled on alcohol.

Fuller's Spiral Cylindrical Slide Rule
- Description
- This rule consists of an outer wooden cylinder that slides up and down and rotates. Two brass rings lined with felt are inside this cylinder. The cylinder is covered with paper marked with a single spiral logarithmic scale graduated into 7250 parts and having a length, according to the maker, of 500 inches (nearly 42 feet). Inside the outer cylinder is a longer wooden cylinder, covered with paper marked with decimal, conversion, and sine tables. A solid mahogany handle is at one end. A third cylinder of brass is inside the instrument. A brass index is screwed to the top of the handle. A second, longer brass index is screwed to the mahogany base and marked with a scale of equal parts used in finding logarithms.
- The tables on the middle cylinder include: decimal equivalents of feet and inches in feet; decimal equivalents of quarter weights and pounds in hundredweights; decimal equivalents of ounces and pounds in fractions of a pound; decimal equivalents of pounds, shillings, and pence in fractions of a pound; decimal equivalents of pence in shillings; days of the year as a fraction of the year; decimal equivalents of subunits of an acre; properties of various metals and woods; decimal equivalents of minutes of a degree in degrees; the Birmingham wire gauge; various conversion factors (mostly for weights and measures); and natural sines.
- The outer, sliding cylinder is marked near the top: FULLERS SPIRAL SLIDE RULE. Near the bottom is marked: ENTD. STATS. HALL; STANLEY, Maker, LONDON. The bottom is stamped: 1099. The top of the long brass index is engraved: 1099 (/) 98. According to Wayne Feely, these numbers indicate the instrument has serial number 1099 and was made in 1898.
- The rule is in a rectangular mahogany case marked in script on the top: Calculator. A blue sticker attached to the inside lid of the case reads: DRAWING MATERIAL (/) FRED. A. SCHMIDT. WASHINGTON D.C. (/) 516 (/) 9TH ST. (/) BRANCH (/) 1722 (/) PA. AVE. (/) TRADE MARK (beneath a drawing of intertwined dividers, right-angled ruler, and French curve). The inside of the lid is also stamped: MADE IN GREAT BRITAIN. A yellow rectangular label is printed: To H.M. Government Science & Art Depnt. Council of India, Admiralty, &c. (/) MADE BY (/) W. F. STANLEY, (/) Optical, Philosophical & Mathematical (/) INSTRUMENT MANUFACTURER, (/) ENGINE DIVIDER, &c. (/) MATHEMATICAL DEPARTMENT, GREAT TURNSTILE, HOLBORN, W.C.
- George Fuller, professor of civil engineering at Queen's University in Belfast, Ireland, patented this instrument in 1878. The Stanley firm made about 14,000 Fuller's spiral slide rules over nearly one hundred years. According to Boyd's Directory of the District of Columbia, Fred A. Schmidt, vendor of draftsmen's supplies, moved from 504 9th Street N.W. to 516 9th Street, with a branch at 1722 Pennsylvania Avenue, between 1895 and 1900.
- According to the donor, this example came from the family of her first husband, Fred Robert Troll (1920–1971), a sanitary engineer who attended Columbia University. The original purchaser may have been his father, Frank Troll, or his uncle, who was an artist who traveled frequently.

- This aluminum ten-inch linear duplex slide rule is coated in Pickett's "Eye Saver" yellow plastic. The flat nylon indicator is screwed within a white plastic frame. The front top of the base has three extended cube root scales (one for numbers with 1, 4, 7, 10, or more digits before the decimal point; one for numbers with 2, 5, 8, 11, or more digits; and one for numbers with 3, 6, 9, 12, or more digits) and a DF scale. The front bottom of the base has D, DI, and square root scales. The top square root scale gives roots of numbers on the D scale with an odd number of digits before the decimal point; the lower square root scale gives roots of numbers with an even number of digits. The front of the slide has CF, CIF, double T, ST, S, CI, and C scales.
- The left end of the slide is marked: MODEL N4-ES (/) Vector-Type LOG LOG (/) DUAL-BASE SPEED RULE. The right end has "Pickett" in script on a triangle with a dot at one point. MADE IN U.S.A. appears beneath the logo. This form of logo was in use from 1958 to 1962. The style of the grooved stamped aluminum posts is also consisted with this timeframe.
- The top back of the base has LL1, LL2, and DF/M scales. D, LL3, and LL4 scales are on the bottom of the base. The back of the slide has CF/M, TH, SH, Ln, L, CI, and C scales. The back of the slide is marked at the left end: COPYRIGHT 1959© (/) PATENT APPLIED FOR. The right end is marked: PICKETT (/) ALL METAL (/) SLIDE RULES (/) PICKETT & ECKEL INC. (/) CHICAGO ILL. U.S.A. The mention on the instrument of a patent application may refer to a patent for a case issued to John W. Pickett in 1960. Pickett was the son of company founder Ross C. Pickett and served as president of the firm from 1957 to 1967.
- The slide rule is in a red-brown leather case lined in white plastic. The triangular Pickett logo is stamped in gold on the front of the case, and a metal ring on the back is for a leather strap (no longer with the instrument) that can be hung around a belt loop. See 1980.0097.04 for instructions.
- The donor, engineer Edgar F. Peebles, obtained this slide rule free of charge as a replacement when the numbers came off the slide rule he had used in college. He first used it from 1959 to 1965 in the satellite control facility of the Air Force at Sunnyvale, Calif. He then used it as a down range representative for Lockheed Missiles and Space Company from 1965 to 1968 in tests of the Polaris missile. Finally, from 1968 to 1969 he used the slide rule in the checkout area of the test Polaris missile manufacturing plant in Sunnydale.

Route 66 Pavement, 1932
- Description
- The nation's first network of highways, built in the late 1920s and 1930s, created new opportunities for motorists and small business owners. It also created a perception that highways benefited ordinary Americans, enhancing their personal lives and giving them more freedom. These advantages contrasted with railroads, which benefited corporations and allowed them to control people's movements and the cost of their travels. In 2000, Oklahoma truckers moved 50 feet of concrete pavement from U.S. 66 to the collections of the National Museum of American History to mark the significance of U.S. numbered highways, and Route 66 as a prime example.
- In 1926, almost 60 years after the first transcontinental railroad was completed, U. S. 66 was conceived as a public thoroughfare linking the Midwest, Southwest, and southern California. Its all-season route soon brought heavy traffic. Motorists and business owners adapted Route 66 for their needs and oriented their lives around it. Some earned a living by driving a truck or operating a roadside business, while others enjoyed leisure trips, advertised products, or moved to new homes. Clusters of roadside buildings made Route 66 the main street of a new community—one that was of, by, and for people on the move.
- Route 66 also served as a conduit for mass migrations of workers, farmers, and their families who saw the highway as a path to a better life. During the Depression, Midwesterners saw it as a way out of hard times and failed farms, and they followed it to seek jobs in the Southwest and California. G.I.s traveled to defense camps during World War II, and after the war they settled in new homes nearby. Hordes of vacationers followed the advice of songwriters Bobby and Cynthia Troup: "Get your kicks on Route 66." Americans relied on Route 66 to change their circumstances for the better, and the highway earned a special place in American culture. Today, historians commemorate its importance.

Family Fallout Shelter
- Description
- The family fallout shelter represents the public policy assumptions of the atomic age, namely, that with enough preparation, the American family and with it the nation's social and political fabric would survive a nuclear attack. This free-standing, double-hulled steel shelter was installed beneath the front yard of Mr. and Mrs. Murland E. Anderson of Ft. Wayne, Indiana. The Andersons purchased their shelter from J. L. Haverstock, a Ft. Wayne realtor who began selling family fallout shelters as a sideline in early 1955 after reading a promotional Life magazine article.
- The Andersons maintained the shelter from its installation in 1955 through the 1960s, a period spanning the development of the hydrogen bomb and the Cuban missile crisis. Insufficiently anchored against Ft. Wayne's high water table when first installed, the shelter popped to the surface of the Anderson front yard in time for the Cuban missile crisis and was quickly reinterred in a frenzy of shelter building activity in 1961. The donors purchased the property, including the shelter, from the Andersons in 1968.

Pickett N15-T Hydraulic Duplex Slide Rule for Georgia Iron Works
- Description
- From the 1650s people have devised special-purpose slide rules for tasks such as carpentry and tax collection. In 1961 Danforth (Danny) W. Hagler of the Georgia Iron Works Company in Augusta, Ga., designed this slide rule to replace the 100-page notebook of graphs carried by each GIW engineer. GIW also distributed the rule to customers to assist with ordering and operating pumps and pipelines. Pickett & Eckel, the California slide rule manufacturer, assisted with the design and produced the slide rules. For Pickett company history, see 1998.0119.02 and 2000.0203.01.
- This ten-inch, two-sided white aluminum instrument has metal endpieces and a nylon cursor with white plastic edges. The front has logarithmic scales for calculating the kinetic energy and flow rate of a liquid or slurry moving through a pipeline. The top of the base is marked: HYDRAULIC SLIDE RULE (/) GEORGIA IRON WORKS CO. (/) EST. 1891 (/) AUGUSTA GEORGIA. The left end of the slide has a GIW logo. The right end of the slide has the triangular Pickett logo used between 1958 and 1962 and is marked: 338. The bottom of the base is marked: DESIGNED BY D. W. HAGLER.
- The back has logarithmic scales for determining the head produced by a pump, impeller peripheral speed, brake horsepower, and specific speed. Standard C and D scales were added around 1969. The right end of the slide is marked: PICKETT (/) MODEL N 15-T (/) 337. The rule fits in an orange leather case with a belt loop. The front of the case is marked: HYDRAULIC SLIDE RULE (/) GIW (/) D. W. HAGLER (/) Pickett. The case fits inside a redwood box.
- This particular rule was Hagler's personal example of the instrument in production. GIW was his family's business, and his brother, Tom, wrote an instruction manual for the rule (2009.0100.02). Hagler went on to work on computer software for production control. He sold his interest in GIW in 1986.

Instruction Manual for Georgia Iron Works Hydraulic Slide Rule
- Description
- The citation information for this 20-page stapled booklet is: T. W. Hagler, Jr., GIW Hydraulic Slide Rule Instructions [and] Formulas, rev. ed. (Georgia Iron Works Co., 1969). Tom Hagler wrote this explanation of the slide rule designed by his brother, Danny, for the pump manufacturing firm owned by their family in Grovetown, Ga. The rule made it easier for the company's engineers to make calculations related to the flow of slurry in pipelines and pumps. See 2009.0100.01. The rule illustrated in this booklet, which has C and D scales, is a later version of the instrument than the example in the collections. The booklet also contains instructions for caring for the rule that presumably came from its maker, Pickett Industries (formerly Pickett & Eckel) of Santa Barbara, Calif.
