Smoker's pipe

A smoker's pipe comprising a bowl portion defining therein both a tobacco-receiving cavity and, in the lower regions thereof below said tobacco-receiving cavity, a socket, said socket extending transversely of the lower regions of the bowl portion and having an open end and a closed end, the socket having a sidewall tapering inwardly from said open end to said closed end thereof, the bowl portion further defining therein a passageway interconnecting said cavity with said socket, the pipe further comprising a stem portion having a first end region provided with a tapering surface so as to be a close push-fit in the socket of the bowl portion, and an opposed end region for location in a smoker's mouth, the stem portion defining therein a bore extending from the opposed end region thereof to terminate in the tapering surface of the first end region and communicating directly into, to form a continuation of, the passageway in the bowl portion, the pipe having formed therein, below the tobacco-receiving cavity in the bowl portion, a primary reservoir at the closed end of the socket, the pipe further having formed therein, below the tobacco receiving cavity in the bowl portion, a relatively narrow groove extending in a direction away from the bore in the stem portion and the passageway in the bowl portion toward the closed end of the socket and forming a relatively narrow channel providing communication between said bore in said stem portion and said passageway in said bowl portion and the upper regions of said primary reservoir whereby smoke flowing from the bowl portion to the stem portion substantially bypasses said primary reservoir, the dimensions of said primary reservoir being substantially greater than those of said channel the bowl portion and stem portion being rotatable relative to one another about the longitudinal axis of the stem portion between a normal position in which the passageway in the bowl portion forms a continuation of the bore in the stem portion, and a displaced position in which said passageway is disconnected from said bore.
