Communications

Tools of communication have transformed American society time and again over the past two centuries. The Museum has preserved many instruments of these changes, from printing presses to personal digital assistants.

The collections include hundreds of artifacts from the printing trade and related fields, including papermaking equipment, wood and metal type collections, bookbinding tools, and typesetting machines. Benjamin Franklin is said to have used one of the printing presses in the collection in 1726.

More than 7,000 objects chart the evolution of electronic communications, including the original telegraph of Samuel Morse and Alexander Graham Bell's early telephones. Radios, televisions, tape recorders, and the tools of the computer age are part of the collections, along with wireless phones and a satellite tracking system.

This patent model demonstrates an invention for an artificial blast for typecasting machines; the invention was granted patent number 11955. This device was intended for small type molds, which were apt to overheat at fast casting rates.
Description (Brief)
This patent model demonstrates an invention for an artificial blast for typecasting machines; the invention was granted patent number 11955. This device was intended for small type molds, which were apt to overheat at fast casting rates. A blower, operated by a steam engine, drove air through a wooden tube around the casting room. Tin pipes from the tube supplied each casting machine with a double blast of air, one directed at the fuel to fire it, the second at the mold to cool it. George Bruce (1781-1866) followed his brother David to America from Scotland in 1795. The brothers first worked around the printing trades, and in 1816 set up their own type foundry. David retired in 1822 and was followed in the business by his son David Jr., author of the patents listed above.

Description (Brief)
This patent model demonstrates an invention for a mold that made blocks that were used in printing carpets or wall paper; the invention was granted patent number 10630. The design, formed of short and long pieces of type, was set up in a square casting box. The printing block was then cast in any suitable material such as type metal, plaster-of-paris, vulcanized rubber, or, by preference, gutta percha - a popular material in the mid nineteenth century.

Description (Brief)
This patent model demonstrates an invention for a rotary printing press; it was granted patent number 9987. The press had several impression cylinders and inking stations arranged around a large type cylinder. A web of paper was moistened and folded concertina-fashion for feeding. It was printed at the first series of impression cylinders and refolded. Then it was turned, and printed on the other side at the next series. Finally, it was cut into sheets. According to Stephen D. Tucker’s History of R. Hoe & Company, this patent was bought by R. Hoe & Co., probably more to keep it out of the market than with a mind to its development.
