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.
The intention of this invention is to enable the smoking of tobacco type products without affecting the environment. It is comprised of a hat that covers the head of the smoker, a fan for the intake of both contaminated and uncontaminated air and a filtration, purification and deionization system for removal of smoke-related odors, positive ions and an exhaust system for expelling the filtered, optionally scented air (and huddled masses yearning to be breathe free) from the hat.
The Smoker's Hat is thus a highly unusual air filtration unit. By enclosing the smoker’s head in a miniature chamber (from which there is no escape) cigarette smoke is contained until it can be arrested and charged. A built-in ventilation and exhaust system filters purifies and de-ionizes the air before releasing it back into the atmosphere. According to the inventor, this device is meant to “put the smoker and the non-smoker on equal footing.”
Other inventors have dealt with the most unpopular vice of smoking with wit and a smile. Consider Steve Levenstein’s two articles, “Japan Tobacco's Cheerfully Chiding 'Smoking Manners for Adults' Ads, Part 2 and his “Kool Boost Cigarettes Have a Ball with Menthol,”
Whatever floats your boat, but speaking for myself, I will pass on the Smoker’s Hat.
