Abstract

A smoking pipe which is characterized by an improved stem which includes a condenser portion provided with a groove having a configuration which increases the effective path of the smoke drawn from the bowl to the user. The condenser portion is slideably and removably mounted in the tubular stem. The stem includes a conical nest portion having an upper shoulder and a lower opening and a pair of aligned openings adapted to receive the inner end of the condenser portion. The lower end of the bowl has a conical exterior which mates with the conical nest portion and has a through passage adapted to receive the condenser portion whereby the inner end of the condenser portion removably secures the bowl in said nest portion. Suitable passages are provided whereby smoke can be drawn from the bowl, through the condenser portion and through a mouthpiece connected to the outer end of the stem. A second embodiment is disclosed wherein an upper and lower annular shoulder on the bowl cooperate with a through hole in the nest portion to assure proper and vertical and rotational alignment between the bowl and nest portion. In addition, the same annular shoulders of the bowl cooperate with the inner end of the condenser portion to appropriately align the smoke-receiving passages therein to assure the passage of smoke through the desired sequence of smoke-receiving passages before being emitted through the mouthpiece.
