Edison "New Year's Eve" Lamp

Description

Thomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention, the first practical electric incandescent lamp, which took place at his Menlo Park, New Jersey, laboratory on New Year's Eve, 1879.

As the quintessential American inventor-hero, Edison personified the ideal of the hardworking self-made man. He received a record 1,093 patents and became a skilled entrepreneur. Though occasionally unsuccessful, Edison and his team developed many practical devices in his "invention factory," and fostered faith in technological progress.

The Propeller Indiana’s “Philadelphia Wheel”

Description

Indiana's propeller was manufactured by Spang & Co. of Pittsburgh, PA, as stamped on one of the blades. This firm, a large iron manufacturing company centered in Pittsburgh, PA, was founded in 1828 and was one of the earliest and largest manufacturers of iron products in the United States.

The hub of the propeller is cast iron; the blades are rolled iron. One of the intact blades is chipped and dented, suggesting a collision. Another blade is missing outside the yellow line, which marks where a large section broke loose, probably from hitting an object in the water. This piece struck the Indiana's sternpost, literally “shivered her timbers,” and started the leak that sank the ship. The blade broke off completely when the ship struck the lakebed and was found at the wreck site, buried in the sand under the stern post. It is reproduced here in fiberglass.

The closest design is by Richard Loper of Philadelphia, who registered three propeller-related patents in 1844 and 1845 and licensed his ideas to shipbuilders Reany, Neafie & Co., also of Philadelphia. Contemporary accounts state that Loper’s design was the most popular in the Great Lakes region, and some Lakes propeller manufacturers even advertised his design as the “Philadelphia Wheel.”

Model, LNG Carrier Methane Shirley Elisabeth

Description

Liquid natural gas (LNG) is composed mostly of methane (80–99%). For shipping, it is chilled to -260°F, at which point it is condensed into a liquid 1/600 of its original volume. It is transported globally in this form aboard ships with insulated containers that offload it at special terminals.

LNG tankers have been around the United States since 1959, when the first cargo was exported from Lake Charles, Louisiana, to England. There are around 200 LNG tankers in service in 2007, and nearly that many more are on order at specialized shipyards to meet the globe’s growing demand for this source of energy.

LNG tankers have completed more than 40,000 voyages without serious incident; they have the best safety record of any category of commercial shipping. However, they are among the world’s most expensive and difficult ships to build.

Methane Shirley Elisabeth is one of the newest types of LNG tankers, having been delivered to its owners in March 2007. Its double hulls, separated by six feet of seawater, protect the four gas tanks, which are refrigerated and insulated to maintain the -260°F temperature. The tanks, or membranes, consist of layers of stainless steel and other materials alternating with thick foam insulation. The insides of the membranes are lined with stainless steel, corrugated in two dimensions to prevent the frozen gas from sloshing around inside.

Model of Edison's Pearl Street power station

Description

This scale model of Thomas Edison's Pearl Street power station was made in 1927. It demonstrates the internal arrangement of generating equipment and can be operated by means of a small electric motor in the base.

The first floor contained the boiler room and coal-handling equipment. Steam created by the boilers operated Porter-Allen horizontal steam engines on the second floor. The engines powered large Edison electrical generators nicknamed "Jumbo" after the famous elephant. Control and switching equipment were housed on the third and fourth floors.

The site for Edison's generating station had to satisfy both engineering and business needs. Because Edison used 100 volt direct current to power his new light bulbs, customers could be no further than ½ mile from the generator. But he needed a high profile location to promote the system. Edison chose a site in the heart of New York's financial district, 255 and 257 Pearl Street. On 4 September 1882, he threw a switch in the office of one of his main investors, J. Pierpont Morgan, and initiated service to the area.

A fire damaged the station extensively in 1890 but Edison and his men worked around the clock for 11 days to restore service. The station was taken out of service and dismantled in 1895, the building sold and later demolished. The New York Edison Company placed a commemorative plaque at the site in 1917.

Mauzey’s Patent Model of a Solar Heater – 1880

Description

This model was filed with the application to the U.S. Patent Office for Patent Number 227,028 issued to James P. Mauzey of Blackfoot, Montana Territory on April 27, 1880. His patent was for a new and improved solar heater. Mr. Mauzey’s design provided for a series of reflecting mirrors mounted on a rectangular frame which could be oriented so as to focus the sun’s rays upon an object to be heated. The image of the patent model shows the frame and mirrors. The frame would be oriented to point the central, oval shaped mirror directly at the sun. This mirror was shaped and oriented so as to focus the sun’s rays along a line at some distance behind the mirror frame assembly. Additional mirror elements were mounted within the frame as shown, and these too were designed to focus energy at the same distance behind the frame. The brown colored rod and material at the top of the frame modeled a curtain which could be rolled across the frame to block the mirrors as necessary for repair or adjustment. The frame assembly shown in the image was intended to be mounted on a supporting base which could be used to tilt the frame up or down to track the sun’s position in the sky. The base was in turn mounted on wheels or rollers to allow additional adjustments to track the sun. The object to be heated would be located on the base at the focal point of the mirrors. Additionally, the mirror assembly could be moved up or down relative to the base allowing for an accurate focus on the object to be heated. Diagrams showing the complete design of the heater can be found in the patent document online www.USPTO.gov/patents/process/search/index.jsp). Research of available trade literature and other sources has not revealed any commercial use that may have made use of Mr. Mauzey’s invention. His work was mentioned by Charles H. Pope, a solar heating advocate, in his 1903 book titled Solar Heat: Its Practical Applications. However, Mr. Pope indicated no additional information on Mauzey had been found.

The patent model is constructed of tin, wood and fabric. It models the mirror assembly and curtain mechanism. Also shown are the side arms that would have attached the assembly to the supporting base.

H. M. Wood Windmill Patent Model

Description

During most of the 19th century, the U.S. Patent Office required inventors seeking patent protection to submit both a written application and a three-dimensional model. This wood and metal patent model of a windmill succeeded in gaining its inventor, H. M. Wood, Patent Number 222,340, which was issued on December 2, 1879. As farms spread into the American heartland, windmills proved an extremely important technology, allowing settlers to use the renewable power of wind to pump groundwater for agricultural and household use. Efficiency and reliability were key attributes for rural windmills, and professional and lay inventors experimented with hundreds of design variations throughout the years.

Model of Bucyrus-Erie Stripping Shovel

Description

In 1960, the Bucyrus-Erie Company of South Milwaukee, Wisconsin, presented this 14-inch-high, scale model of what was to become the world's largest stripping shovel to President Dwight D. Eisenhower. Later that year, the President transferred this gift to the Smithsonian Institution. The Bucyrus-Erie Company had custom-designed this monster machine for the Peabody Coal Company. Bucyrus-Erie engineers anticipated that they would need two years to manufacture the behemoth, and an additional six months to assemble it at the site of the open-pit mine. (They planned to ship the machine's parts in over 250 railcars.) When finished, the shovel would weigh 7,000 tons, soar to the roofline of a 20-story building (some 220 feet high), and be able to extend its enormous 115-cubic-yard dipper over 460 feet, or about the length of an average city block. (The dipper's capacity would equal that of about six stand-sized dump trucks.) Fifty electric motors-ranging from 1/4 to 3,000 horsepower-would power the shovel, which was designed to be controlled by a single operator, perched in a cab five stories high. Publicists for Bucyrus-Erie called this the "largest self-powered mobile land vehicle ever built."

Carrier Centrifugal Refrigeration Compressor

Description

The first successful mechanical refrigeration equipment was patented soon after the Civil War, but the large size and high cost of these early machines restricted their use to industrial processes. In his effort to improve mechanical air-conditioning systems, Willis Haviland Carrier (1876-1950) introduced the first practical centrifugal refrigeration compressor in 1922 (pictured here). This machine provided the foundation for safer, smaller, and more powerful and efficient large-scale air-conditioning systems.

Prior to the introduction of the centrifugal compressor--which compressed the refrigerant gas through the centrifugal force created by rotors spinning at high speed—reciprocating compressors compressed the refrigerant by the action of pistons inside cylinders, much like an automobile engine. The centrifugal compressor proved an extremely important advancement and paved the way for "comfort" air conditioning in theaters, department stores, hospitals, banks, offices, and hotels.

Carrier installed this initial compressor at his company's Newark, N.J., offices, where he gave the first public demonstration of the machine on May 22, 1922. Two years later, he sold the compressor to the Onondaga Pottery Company of Syracuse, N.Y., for the air conditioning of its lithography plant. The machine remained in use there until about 1957, when the Carrier Company repurchased the compressor for donation to the Smithsonian. Earlier, in 1924, the Carrier Company had installed centrifugal refrigeration machines in the J. L. Hudson department store in Detroit and the Palace Theater in Dallas, thereby introducing the phrase "air conditioning" into the public vocabulary.

Alarm Clock

Description

Alarm Clock by Rube Goldberg, circa 1970. This non-working, sculpted model signed by Rube Goldberg was crafted [during the 1960s] to replicate a cartoon from the series The Inventions of Professor Lucifer Gorgonzola Butts that he drew for between 1914 and 1964.

Inscription: At 6 a.m. garbage man picks up ashcan, causing mule to kick over statue of Indian warrior. Arrow punctures bucket and ice cubes fall on false teeth, causing them to chatter and nip elephant's tail. Elephant raises his trunk in pain, pressing lever which starts toy maestro to lead quartet in sad song. Sentimental girl breaks down and cries into flower pot, causing flower to grow and tickle man's feet. He rocks with laughter, starting machine that rings gong and slides sleeper out of bed into slippers on wheels, which propel him into bathroom where cold shower really wakes him up.
