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.

Otis King's Pocket Calculator Model L Cylindrical Slide Rule
- Description
- This six-inch cylindrical slide rule consists of a chromium-plated holder, a metal cylinder that slides into the holder, and a black metal tube that fits around and slides up and down on the cylinder. The telescoping rule is ten inches long when extended and equivalent to a rectangular slide rule 66 feet in length. Two short white lines on the tube and a black mark on the chrome cap at the end of the cylinder serve as the indicator. A paper spiral logarithmic scale is attached to the top half of the holder. A second, linear and logarithmic, paper scale is attached to the cylinder. The logarithmic scales are used to multiply and divide, and the linear scale is used to find logarithms.
- At the top of the cylinder is printed: PATENT No 183723. At the bottom of the cylinder is printed: OTIS KING'S POCKET CALCULATOR; SCALE No 430. The top of the scale on the holder is printed: SCALE No 429; COPYRIGHT. The bottom is printed: OTIS KING'S PATENT No 183723. The end of the holder is engraved: MADE IN (/) Y9481 (/) ENGLAND.
- Otis Carter Formby King invented this form of slide rule in 1921, and Carbic Limited of London, England, manufactured it until 1972. The serial number, Y9481, suggests a date about 1965–1969 for this example. A collector of computing devices donated it to the Smithsonian.

Routledge's Engineer Linear Slide Rule
- Description
- This is a two-foot, two-fold boxwood rule with a brass hinge and endpieces. Half of one side is a slide rule with A and D scales on the base and B and C scales on the slide. As with MA*306697.01, the C scale is the same as the A and B scales (the square of the D scale), instead of the same as the D scale, as on modern Mannheim slide rules. Below the D scale is marked: SQUARE CYLINDER GLOBE (3 times) ROUTLEDGE'S ENGINEER.
- The first three marks form headings for the tables on the other half of this side when the instrument is folded. The tables give conversion factors from the volumes of geometric solids to units of volume, in both the "old" and imperial systems; conversion factors from the volumes of geometric solids to the weights in pounds of various substances; the areas of polygons from 5 to 12 sides; the gauge points of a circle; and gauge points for pumping engines, to find the diameters of steam cylinders that will work pumps of specified diameter at 7 pounds per square inch.
- The other side has a scale of 24 inches along one edge, divided to sixteenths of an inch for 9 inches and to eighths of an inch for the rest of the scale. There are also scales for making scale drawings that are 1, 3/4, 1/2, and 1/4 inches to the foot. This side is marked: T. ASTON THE ORIGINAL MAKER WARRANTED. One outside edge has scales for 10 and 12 parts to the inch; the other outside edge divides one foot into 100 parts.
- This form of slide rule was invented by Joshua Routledge, a seller of iron goods, in 1808 or 1809. He discussed it in the 1813 (4th) edition of Instructions for the Engineer's Improved Sliding Rule. According to Gloria Clifton, there were two rule makers named Thomas Aston, presumably a father and son, who were in business at various addresses in Birmingham, England, from 1818 to 1862. The references to pre-imperial system units of measure suggest the rule might have been made shortly after the imperial system was adopted in 1824. This instrument was found in the home of Grace Speer, granddaughter of Alfred Speer (1823–1910), an inventor and wine merchant in Passaic, N.J.

ECOBRA 1611 Duplex Slide Rule
- Description
- This ten-inch aluminum linear duplex slide rule is coated with white enamel and has aluminum endpieces. One side of the base has scales for sin/cos, tg/ctg (tangent/cotangent), DF, D, and the square root of 1 – x2 (a Pythagorean or P scale). On the slide are CF, CI, and C scales. The right end of the slide is marked: ECO BRA (/) Nr. 1611. The lower right corner of the base is marked: System (/) DARMSTADT. On the other side, the base has K, A, LL3, LL2, and LL1 scales. The slide has B, lg, and C scales. The numbers on the C, LL3, LL2, and LL1 scales are green, which is unusual. The indicator is plastic with aluminum edges. The letter Q is on the hairline on one side. On the other side, Q is on the hairline and W and PS are on shorter hairlines at the top of the indicator. These hairlines are for circle conversion and peripheral horsepower conversion, respectively.
- The rule fits in a cardboard box covered with maroon synthetic leather. The top edge of the box is marked No. 1611. The front is marked with the Ecobra logo, and the back is marked MADE IN GERMANY.
- Alwin Walther (1898–1967) of the Technische Hochschule in Darmstadt, Germany, developed the Darmstadt system of scales in 1934. His arrangement was aimed particularly at engineers. ECOBRA or Eco Bra was a brand name of Bayerische Reisszeugfabrik, a Nuremberg maker of drawing instruments that was purchased by Joseph Dietzgen in 1909. The company began producing slide rules before World War II, and after the war, Eugene Dietzgen Company of Chicago distributed ECOBRA rules in the United States. Metal rules were more popular in the United States than they were in Europe.

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.

Pickett 904-ES Decimal Keeper Duplex Slide Rule
- Description
- This aluminum duplex slide rule has a yellow coating and a clear plastic indicator. The "ES" in the model number refers to the rule's "Eye Saver" yellow color. The rule and indicator are held together with aluminum braces that have protruding grooves. The front of the rule has K, A, DF, D, and L scales, with CF, S, T, CI, and C scales on the slide. The scales are 9-1/2 inches long. The back of the rule has a D* scale, with T*, S* Cl*, and C* scales on the slide. Instead of covering the typical one decade of C and D scales, the scales with asterisks cover twenty decades, from 1010 to 10-10. These scales helped inexperienced users keep track of the decimal point. They performed their calculation first on the back, to determine the order of magnitude, and then a second time on the front, to make the answer precise to three significant figures.
- The front of the slide is marked: MODEL 904-ES (/) TRIG AND (/) DECIMAL KEEPER (/) SPEED RULE. A Pickett logo is at the other end of the slide, with the number 47 printed above the logo. The back of the rule is marked: PATENT (/) APPLIED FOR; DECIMAL KEEPER; PICKETT & ECKEL, INC. (/) CHICAGO 3, ILL. - ALHAMBRA, CAL. The logo on this rule is that used by Pickett from 1958 to 1962. The shape and material of the cursor and the braces suggest a date of 1957–1959. Hence, the object appears to have a rough date of 1958–1959.
- The donor patented an "automatic decimal point slide rule" and assigned the patent to Pickett. He also distributed Pickett slide rules through his own mail order firm of Devonics, Inc.
- The rule was received in a plastic bag. For somewhat related documentation, see 1995.0126.04. See also Lawrence J. Kamm, "Automatic Decimal Point Slide Rule" (U.S. Patent 2,893,630 issued July 7, 1959).
