Jerome Lemelson's Patents

Jerome Lemelson was one of America's most prolific inventors, with nearly 600 patents to his name and others still pending. His versatile mind produced inventions in communications and medical technologies, robotics and machine vision, and a variety of industrial processes. He also invented toys--inflatable toys, jumping toys, toys with propellers, toys that run on tracks, target games, dolls and more. In fact, Lemelson's first patent, issued in 1953, was for a variation on the propeller beanie, operated by blowing through a tube (his patent drawings are above and an artist's vision of the beanie is at the top of this page).
