2 Claims.
This invention relates to smoking pipes and has for one of its objects the provision of a pipe so constructed that the smoke drawn through the stem is caused to move through a tortuous path whereby the moisture, burnt tobacco shreds and impurities are prevented from reaching the mouth of the smoker, and a so called cool and dry smoke is attained.
In carrying out the invention, I provide a smoke tube within the pipe shank having a lateral outlet opening communicating with longitudinal passages or flutings in a sleeve that surrounds the stem outlet; said sleeve being open at an end facing the bowl and provided with outer flutings or passages through which the smoke passes to enter the smoke passage in the stem and then to reach the mouth of the smoker.
With this arrangement, the smoke is drawn first in one direction; then it reverses its direction of flow and moves in a direction toward the bowl and then flows again in the first direction and out of the stem and into the mouth of the smoker. Such tortuous movement of the smoke aids in the provision of one or more traps in which moisture, burnt tobacco particles and other impurities may collect and thereby be prevented from entering the mouth of the smoker.
A further object of the invention is to provide a pipe constructed as above described wherein the various co-operating parts are so assembled that they may be very easily dismantled when desired to facilitate a rapid and thorough cleaning of the pipe.
In the accompanying drawing, wherein an embodiment of the invention is shown, Fig. 1 is a side elevation, partly in section, of a pipe constructed in accordance with the invention; Fig. 2 is a sectional view through a portion of the stem; and Fig. 3 is a sectional view on the line 3-3 of Fig. 2, looking in the direction of the arrows.
The pipe is provided with a bowl I of conventional form from which extends the integral shank 2. Fitted in the shank 2 and having one of its ends in communication with the bowl, is a tube 3 forming a smoke passage. Said tube is surrounded by a threadedportion 4, which can be integrally formed on the tube or the tube can be inserted within it with a force fit. The threaded portion is tightly fitted in the end of the shank 2.
Near its free end which projects for some distance away from the shank 2, the tube 3 is provided in its wall with an outlet opening 5. This opening, leading laterally from the smoke passage through the tube 3, is enclosed by a fluted sleeve 6 which fits over a considerable portion of the tube 3. The sleeve 6, because of its fluted shape, is formed with interior longitudinal passages which convey smoke emanating from the outlet opening 5 in a direction toward the threaded portion 4. The fluted sleeve is provided with outer channels or passages 8 which serve to convey the smoke in an opposite direction through the chamber 9 and then into the smoke passage in of the stem or bit i l of the pipe.
The fluted sleeve 6 is held in position on the tube 3 by means of a threaded element or head i2, which threads into and serves as a closure for the free end of the tube 3. Provided on the head [2 is a flange or disk l3 which extends over and closes the ends of the inner passages 'l in the fluted sleeve 6, said sleeve being clamped between the disk i3 and a shoulder It provided on the tube 3 near the threaded portion l. The shoulder I4 is of such size that it does not close the passages l.
Fitted into the stem or bit I! is an internally threaded bushing l5 which is received upon the threaded portion 4 to detachably secure the stem or bit II to the shank. The chamber 9 in the stem encloses the fluted sleeve 6 and the portion of the tube 3 surrounded by the fluted sleeve.
From the foregoing, the operation of the improved pipe will be readily understood. Smoke drawn through the tube 3 passes out of the outlet opening 5 and into the interior passages I of the fluted sleeve 6. The smoke is then drawn in a reverse direction or toward the shoulder M where it emanates from the open ends of passages I and then moves in a reverse direction through the channels or passages 8, through the chamber 9 and passes therefrom into the smoke passage I0 and into the mouth of the smoker.
By the arrangement of passages described, the smoke moves through a tortuous path so that moisture, burnt tobacco particles, and other impurities are trapped either in the end of the tube 3 or in the chamber 9. The pipe can easily be cleaned of these accumulations since the removal of the threaded element 12 opens up the end of the tube 3, permits removal of the fluted sleeve 6 and uncovers the outlet opening 5 for cleaning.
What I claim is:
1. In a pipe, a bowl, a shank extending therefrom, a tube communicating at one end with the interior of the bowl and having its other end projecting from the end of the shank, said tube having an integrally formed threaded portion located at the end of the shank, a stem provided with an internally threaded part removably received on the threaded portion of the tube, the tube having a shoulder of less diameter than its threaded portion, said shoulder being located on the tube adjacent to the threaded portion, the tube having an outlet opening in its side wall at a position remote from the shoulder, a fluted sleeve surrounding the tube, said sleeve having one end in abutment with the shoulder but not closed by said shoulden'a threaded element received into the end of the tube adjacent to the outlet opening and closing said end, said threaded element having an annular flange portion abutting against an end of the fluted sleeve to thereby clamp said sleeve between it and the shoulder on the tube and to close both the end of the tube and the end of the sleeve remote from the shoulder, the fluttings in said sleeve providing inner passages for the conveyance of smoke toward the bowl and,
outer passages for the conveyance of smoke to- Ward the stem.
2. In a pipe, a bowl having a shank, a tube leading therefrom, a. stem threaded on said tube and enclosing the same, an annular shoulder on the tube adjacent to the connection of said tube with the shank, a fluted sleeve of greater diameter than the shoulder surrounding the tube and having one of its ends clamped against the shoulder by means entrant into the tube and supported thereby, the tube being provided with ing outer passages for conveyance of smoke to- V ward the stem, the ends of said passages located at the shoulder being open and unobstructed by said shoulder.
