Abstract:

A pipe to be used for smoking with a bowl, where the tobacco being smoked is burned, having three cavities or chambers defined therein. One of the chambers is a burning chamber wherein the tobacco to be smoked is burned, beneath the burning chamber is a screen, a control valve that varies the diameter of the passage between the burning chamber and a cooling chamber underneath this valve. A second screen separates the cooling chamber from a third chamber, called the filtering chamber. The filtering medium is the same substance being smoked and it is packed and held inside the filtering chamber with a third screen that is placed at the end of the filtering chamber. The third screen in turn is held in place when the bowl is connected to the stem. Finally, a mouthpiece is connected to the stem. The ends of the bowl piece may be interchanged, thereby providing two choices for the size of the burning chamber to be used depending on the amount of substance to be smoked.
