Thomas Jefferson invented a macaroni-making machine, a swivel chair, the moldboard plow, a spherical sundial, a duplication machine, and a cipher wheel that was later "reinvented" prior to World War I and used by the U.S. Army to encrypt messages. Many of Jefferson’s agricultural and mechanical inventions are still in use today, but it is questionable what use he would have ever found (if any) for United States Patent # 4858627 also known as the Smoker’s Hat.
