Telegraph message, printed in Morse code, transcribed and signed by Samuel F. B. Morse. This message was transmitted from Baltimore, Maryland, to Washington, D.C., over the nation's first long-distance telegraph line.
In 1843, Congress allocated $30,000 for Morse (1791-1872) to build an electric telegraph line between Washington and Baltimore. Morse and his partner, Alfred Vail (1807-1859), completed the forty-mile line in May 1844. For the first transmissions, they used a quotation from the Bible, Numbers 23:23: "What hath God wrought," suggested by Annie G. Ellsworth (1826-1900), daughter of Patent Commissioner Henry L. Ellsworth (1791-1858) who was present at the event on 24 May. Morse, in the Capitol, sent the message to Vail at the B&O Railroad's Pratt Street Station in Baltimore. Vail then sent a return message confirming the message he had received.
The original message transmitted by Morse from Washington to Baltimore, dated 24 May 1844, is in the collections of the Library of Congress. The original confirmation message from Vail to Morse is in the collections of the Connecticut Historical Society.
This tape, dated 25 May, is a personal souvenir transmitted by Vail in Baltimore to Morse in Washington the day following the inaugural transmissions. The handwriting on the tape is that of Morse himself. Found in Morse’s papers after his death the tape was donated to the Smithsonian in 1900 by his son Edward, where it has been displayed in many exhibitions.
This patent model demonstrates an invention for sidesticks with several tapering sections, and grooves or steps to guide the quoins on their path; the invention was granted patent number 145574.
This patent model demonstrates an invention for a casting printers’ lead; it was granted patent number 155609. Molten lead was rolled out to thickness between two flexible steel belts, then cut into strips, trimmed, and planed smooth.
This patent model demonstrates an invention for quoins whose two sides were opened or closed by wedges governed by a central double-threaded screw; the invention was granted patent number 139351.
This patent model demonstrates an invention for a combination of quoins and sidesticks which was granted patent number 218518. The quoins swiveled on the ends of wide screws that turned into the sides of the metal sidesticks. A guage in the center of each sidestick told the compositor how far the quoin could be extended.
This metal buckle is stamped into a plain rectangular frame.
The Waterbury Collection tells the story of an important American manufacturer. As evidence of one company’s diverse output, the collection consists of several thousand metal objects and assemblies made in Waterbury, Connecticut, in the Naugatuck Valley from about 1890 to 1930. During the 19th Century, the Naugatuck Valley became a center of brass manufacturing, drawing heavily on the armory manufacturing practice of interchangeable parts.
The Waterbury Button Company traces its beginning to the War of 1812, when Aaron Benedict began crafting uniform buttons. During the nineteenth century the company grew from a small village shop to a large national manufacturer. Its product line expanded to include machine produced brassware such as knobs, hinges, and buckles. The company also experimented with innovative materials such as celluloid in the 1870s and Bakelite in the 1920s. In the spirit of its founding, the company continued to supply uniform buttons and mobilized to meet wartime demands during major conflicts including the Civil War and World War I.
This rich history of product innovation and machine assembly is captured in the more than 7,500 examples of military insignia, civilian emblems, belt plates, buckles, and machine components donated to the museum in 1975. Varying in size from a thumbtack to a soup can, the majority of these objects are composed of metal such as tin, nickel, brass, and other copper and iron alloys. They originally came to the museum mounted on cardboard display boards. At the National Museum of American History, the collection is divided between the Division of Work and Industry and the Division of Armed Forces History. Additional artifacts can be found at the Mattatuck Museum in Waterbury, Connecticut.
This patent model demonstrates an invention for a small, self-inking clockwork press that printed from curved stereotype plates; the invention was granted patent number 71103.
This patent model demonstrates an invention for a pneumatic sheet-feed apparatus consisting of a suction bar and pins to separate and lift the sheets; the invention was granted patent number 160721.
This patent model demonstrates an invention for printers' furniture which was granted patent number 141450. Furniture of a single length was used, and each piece was slotted horizontally from each end to near the middle, so that the side and end pieces could be fitted through each other.

Description
As energy prices soared in the 1970s, lamp makers focused research efforts on raising the energy efficiency of electric lamps. A great deal of effort by many researchers went into designing small fluorescent lamps that might replace a regular incandescent lamp. These efforts led to modern compact fluorescent lamps that use bent or connected tubes, but many other designs were tried. This experimental "partition lamp" from 1978 shows one such design.
Soon after the 1939 introduction of linear fluorescent lamps, inventors began receiving patents for smaller lamps. But they found that the small designs suffered from low energy efficiency and a short life-span. Further research revealed that energy efficiency in fluorescent lamps depends in part on the distance the electric current travels between the two electrodes, called the arc path. A long arc path is more efficient than a short arc path. That's why fluorescent tubes in stores and factories are usually 8 feet (almost 3 meters) long.
Inventors in the 1970s tried many ways of putting a long arc path into a small lamp. In this case there are thin glass walls inside the lamp, dividing it into four chambers. Each chamber is connected in such a way that the electric current travels the length of the lamp four times when moving from one electrode to the other. So the arc path is actually four times longer than the lamp itself, raising the energy efficiency of the lamp. This unit was made by General Electric for experiments on the concept, though other makers were also working on partition lamps.
While the partition design works, it proved to be expensive to manufacture and most lamp makers decided to use thin tubes that could be easily bent and folded while being made.
Lamp characteristics: No base. Two stem assemblies each have tungsten electrodes in a CCC-6 configuration with emitter. Welded connectors, 3-piece leads with lower leads made of stranded wire. Bottom-tipped, T-shaped envelope with internal glass partition that separates the internal space into four connected chambers. Partition is made of two pieces of interlocked glass and is not sealed into the envelope. All glass is clear. No phosphors were used since the experimenter wanted to study the arc path.
This patent model demonstrates an invention for a small self-inking card press which was granted patent number 17405. A traveling frame carried the inking and impression rollers across the fixed type bed and ink plate.
This patent model demonstrates an invention for a type-cutting machine which was granted patent number 31333. The patent details a machine for sawing type from a solid block of letters by first cutting a strip of letters from the block, then notching the strip, and finally cutting apart the letters. The block could be cast by Smith's patent of 1859.
This patent model demonstrates an invention for sidesticks composed of two parts that fitted together, tongue in groove, in such a way that the full length of the stick always pressed on the type, no matter how far the two parts were pulled out. The invention was granted patent number 115136.
