Documents and Teaching Activities Related to Glidden's Patent for Barbed Wire Now Available Online from the National Archives
Washington, DC. . . The National Archives and Records Administration announces a new project in the Digital Classroom section of its Website. "Glidden's Patent Application for Barbed Wire" presents Glidden’s 1874 patent drawing and description, offers suggestions for teaching activities that are correlated to the National Standards for History and the National Standards for Civics and Government, and provides links to images of additional patent drawings available online from the National Archives.
Life in the American West was reshaped by a series of patents for a simple tool that helped ranchers tame the land: barbed wire. Nine patents for improvements to wire fencing were granted by the U.S. Patent Office to American inventors, beginning with Michael Kelly in November 1868 and ending with Joseph Glidden in November 1874. Barbed wire not only simplified the work of the rancher and farmer, but it significantly affected political, social, and economic practices throughout the region. The swift emergence of this highly effective tool as the favored fencing method influenced life in the region as dramatically as the rifle, six-shooter, telegraph, windmill, and locomotive.
The background information describes the development of barbed wire and the teaching activities encourage educators and students to analyze the documents and draw conclusions about the impact of invention on the American West.
"Glidden's Patent Application for Barbed Wire" is the latest in a series of Digital Classroom exercises that the National Archives and Records Administration produces for teachers and students on the Website. Other subjects covered include exercises about the Constitution, the War with Mexico, and Watergate.
A patent protects your invention.
A patent for an invention is a grant of property rights by the U.S. Government through the U.S. Patent and Trademark Office. The patent grant excludes others from making, using, or selling the invention in the United States. The terms "Patent Pending" and "Patent Applied For" are used to inform the public that an application for a patent has been filed. Patent protection does not start until the actual grant of a patent. Marking of an article as patented, when it is not, is illegal and subject to penalty.
