摘要:
A smoker's pipe of the dry bowl type is disclosed which has a ceramic inner bowl secured at its lower end to the lower end of an outer plastic bowl in a manner to space the bowls radially apart for the establishment of a cooling air space between the bowls. The pipe has a stem provided with an auxiliary fresh air inlet that is in communication with one end of a horizontal longitudinally extending passageway located in the bottom of the inner bowl below the combustion chamber and in communication therewith. The other end of the passageway is in communication with a cooling chamber to communicate smoke from the inner bowl to a mouthpiece fitted in the outer end of the stem. 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. A bore having a curved bottom in the mouthpiece cooperates with a slot in the bottom of the smoke passage tube to constrain the smoke to flow over an S-shaped path for enhanced cooling.
