This invention relates to a novel and improved smok~
ing pipe wherein the smoke is cooled and condensed by
being drawn through tortuous passage means.
The primary object of the invention is the provision of
an e?icient and practical smoking pipe of the kind indi

smoke cooling and condensing chamber 38, surrounding
the shank 32. The shank 32 has an axial bore 34, extend
ing therethrough, which, at its inner end, opens to an
axial bore 36 extending through the bit 22.
The bore 34 of the shank 32 opens to the inner end of
a straight passage A which extends longitudinally out
wardly in the stem, at a slight upward and laterally out
ward angle, as indicated in phantom lines in FIGURE 4,
and opens, at its outer end, into an annular upwardly
10 opening groove 40, which is formed in the ?at upper end
42 of the lower bowl section 14, and concentrically sur
rounds the hemispherical recess 2-9, The groove 40 is
rendered discontinuous by a radial partition 44 which ex
