19th century U.S. patent models on display
The exhibition entitled "Spirit of Invention: Nineteenth Century U.S. Patent Models from the Hagley Museum and Library" is currently on display at Yangtze River Civilization Museum, located in Wuhan Garden Expo Park.
The exhibition presents 60 of Hagley's patent models, dating from 1836 to 1890. It covers a broad spectrum of industries, including the areas of engines, transportation, print, light industry, and mining. It showcases stories of each invention and chronicles the development of the U.S. patent and intellectual property system in the 1800s.
Highlighted models include an improved ice cream freezer invented in 1877 and an improved washing machine created in 1871. The exhibition also includes the first American patent license issued in 1797.
Tsinghua University, organizer of the exhibition, said that inventors at that time had to submit models when applying for patents. To impress patent examiners, inventors would normally hire craftsmen to help make exquisite patent models.
The exhibition will continue through September 24 in Wuhan, the last stop of Hagley's traveling exhibition in China. Hagley boasts the world's larges t private collection of patent models.
