  • Smoker's pipe
    Patent number: 4190063
    Abstract: A smoker's pipe has a tobacco bowl for burning tobacco and a stem extending from the bowl. A control system produces a draft via a free flow of air through tobacco in the bowl whereby the tobacco burns freely and evaporates moisture in the tobacco and eliminates nicotine and tar to provide a milder smoke when the pipe is free from drawing and puffing by a smoker. The control system draws smoke from burning tobacco in the bowl through the stem to the smoker's mouth when the smoker draws or puffs.
