  • Patent number: 7434584
    Abstract: A vaporizer device that uses a flame for vaporizing flavor and psychoactive compounds from smoking materials such as tobacco. The present device has a filter unit 34 with a porous flame filter 36. The flame filter 36 can be made of open-cell ceramic or metal foam, sintered ceramic or metal granules or other porous, heat resistant materials. In use, flame is supplied to the flame filter, and inhalation causes ambient air to enter the flame filter as well. The flame exhaust and ambient air are mixed within the flame filter and produce an air stream of intermediate temperature. The intermediate temperature air stream is hot enough to vaporize desirable components from the smoking material, but generally is not hot enough to burn the smoking material. The temperature of the air stream can be controlled by adjusting the amount of flame supplied to the flame filter 36.

The mouthpiece has an insert cluster containing a smoke passage tube and a liquid contaminant tube, the latter of which is received within the open end of a liquid absorber mounted on a plug that is frictionally fitted in a bore formed in the front end of the stem below the bowl assembly.

  • Patent number: 4198993
    Abstract: An article that serves the dual function of a smoking pipe and drinking receptacle, and thereby permits the concurrent smoking of tobacco and consumption of a beverage through use of a single instrument. The article has the general configuration of a mug, comprising an inner shell that forms a reservoir for holding a beverage and a surrounding outer shell having smoke input and output means, a smoke chamber normally containing a smoke filtering agent being provided between the inner and outer shells to accommodate the travel of smoke between said input and output means. The smoke chamber is securely sealed from the reservoir to prevent contamination of the beverage by the smoke or filtering agent, while the inner shell serves to conduct heat between the chamber and reservoir to provide auxiliary cooling of the smoke.

  • 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.

  • Patent number: 4020853
    Abstract: A smoking pipe which can be made of an artistically ornamented ceramic such as porcelain wherein means is provided for maintaining the outer wall at a sufficiently low temperature to permit comfortable handling by the smoker, there being spaced inner and outer bowls with provision for air circulation inwardly and upwardly between the bowls by convection, the convection flow not only serving as a cooling medium but also as an upward draft to assist in keeping the tobacco in a burning condition even while the smoker is not drawing air and smoke through the inner bowl and stem of the pipe. The inner bowl is removably held and sealed about its bottom by a novel sealing arrangement with a yielding heat resistant material such as silicone rubber which also supports part of the smoke passage means leading to the stem.
