Invention and the Patent Model

Closed April 20, 2014

Between the years 1790 and 1880 the U.S. Patent Office required both documentation and a three-dimensional working model to demonstrate each new invention submitted for a patent. The models helped to explain proposed innovations and compare them against similar inventions.

Today patent models provide a glimpse into the 19th century. They reflect the interests and the needs of the period, along with the division of labor between men and women. Many inventions were not successful while others were said to have changed the course of contemporary civilization.

From 1908 to 1926 some 10,000 patent models were transferred from the U.S. Patent Office to the U.S. National Museum at the Smithsonian Institution. The models are now here at the National Museum of American History. This display featured a small selection of models from the collection.
