Artifact Walls - Invention and the Patent Model

Hoe was celebrated for his cylinder press and type-revolving press inventions. This improvement in “Rotary Printing Presses” included type forms which attached to the printing cylinder.

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.

The display is part of the special cases within the museum’s Artifact Walls that highlight anniversaries, new acquisitions to the collections and research findings.
