Invention and the Patent Model

Washington, DC

Location: 1st Floor, Center, History Highlights Case

Between 1790 and 1880, the U.S. Patent Office required a three-dimensional working model of each submission to demonstrate how the invention worked and to compare it against previously patented inventions. The models reflect technological needs during the 19th century, as well as the social roles and division of labor between men and women. This case highlights 20 models from the museum’s collections, including the model for Samuel Morse's telegraph patent.
