Arthur Ehrat invented and patented a breakaway basketball rim, fashioning his prototypes from bolts, metal braces and one key part: a piece of the heavy-duty coil spring on a John Deere cultivator. His invention helped to revolutionize the way basketball is played because players could slam dunk the ball with fewer injuries and without bending the rims or breaking backboards. This collection includes correspondence, legal documents --such as patent papers, litigation files and licensing agreements --photographs and sketches that relate to the basketball invention, as well as materials regarding his two field spreader patents and other invention ideas.
