invention. relatesA to a smoking pipe, and more particularly to improvements in the stem The primary objects of the invention are to provide a pipe tion that'will aiord a dry,- wll not bite the tongue.

lA further object is to clean, cool smoke that provide a stem that pre- -ventssaliva from' the mouthpiece from entering the bowl, thus keeping the bowl dry and free from saliva. 1

Another object is to provide a stem that` pre-S vents thel moist products of combustion or conhaving a stem of novel construc' parts may be of anyalthough I prefer toform the-stem with a flat brier-wood but they may be --teriaL and as separate'parts or coupling sleeve I5.

densation from entering the mouth of the smoker.

A still further object is to provide a stem that permitsA of circulation of smoke in its' passage from the bowl to the mouthpiece so as to effect a cooling of the smoke.

Another object is to provide the stem with on absorber, such as a piece of standard-pipe-cleaner, that absorb the moisture or moist prodn ucts and'will keep the stem clean.

A still further object is to provide a stem hav ing a at bottom surface that serves as-a'convenient rest for the pipe when not in use.

The stem of the pipe'has two longitudinal passages, the upper one of which affords .a direct passage between the bowl and the mouthpiece or bit; while the lower one, which is closed except for two spaced apart openings into the upper passage, constitutes a trap for the moist prod- .ucts of combustionor condensation of tletobacco entering from the bowl, and for saliva entering from the bit, said lower passage also permitting of circulationof the smoke whereby the smoke is cooled.`

The invention is illustrated in the accompanying drawing, in which- Figure f1 is a. .longitudinal section of -a pipe embodying the invention;

Fig, 2 is a fragmentary bottom plan view thereof; Fig. 3 is a vertical section taken on the line 3 3 of Figure 1;

Fig. 4 is a fragmentary Vlongitudinal section of a pipe embodying a modification of the invetio Fig. 5 is a vertical section on line 5-5 through the stem of the modication shown in Fig. 4; and v Fig. 6 is a fragmentary longitudinal section illustrating a further modication of the invention.

Referring to Figs. 1 to 3, the pipe comprises a bowl IU, a

the drawing, and particularly "The two passages IB or closure The present invention relates particularly toA improvements in the stem portion vII which I shall now proceed to describe. The stem has two longitudinally extending passages IE and I'I, separated by a dividing wall or partition I8, and openings I9 and 2U extending through the dividing -wall at spaced apart points for the pur-l pose hereinafter described.

and I1 may be readily formedby drilling the stem. Where the bowl and stem aremade of a single piece of wood.

vthe bottom wall may be formed with an open.-

ing 2| vof a diameter large enough to permit of f'insertion of a drill at an angle to form the openings IS and 20 through the interior wall I 8. The

vopening is subsequently closed by a plug 22 which may be' fixed or detachable.

The upper passage I 6 extends from the end o f the stem to a point near the bowl where it is connected with the bowl by a passage 23 of reduced diameter or cross-sectional area. 'I'he lower passage I1 is preferably longer than the upper one and may extend substantially the entire length of the stem. The open end of the passage I1 .is closed with a detachable screw plug 24 to form avchamber that is closed except for the above mentioned openings I9 and 20. Any suitable absorber, such, for example, as a length of standard pipe-cleaner 25, may be placed in the chamber or passage I'I. If desired, the end 26 of the wire core of the pipecleaner or absorber 25 may beheld detachably by the* plug 24 for convenience in withdrawal and replacement.

In the modication of the invention shown in Figs. 4 and 5, the dividing wall 21 is a separate piece of wood or other suitable material secured within the stem II by tongue and groove joints 28 or in any other suitable manner.

A further modification is inustmted 1n Fig, s

wherein the bowl I8 is a separate part having a screw 29 or the like which is attached to the stem.

In use of the pipe, the smoke is drawn :from

the bowl through the passagel I6 and into the mouth. During its passage the smoke, or part of the smoke, passes into and circulates through the passage l1 and thus aiIords a cooling action. The moist products o! combustion or condensation are trapped through the opening I9 and are caught on the absorber 25 in the chamber I1.

` Any saliva entering from the bit is likewise trapped in said chamber and caught on the absorber through the opening 20. To these ends theopenings I 8 and 20 are preferably disposed as close to the bowl I 0 and the bit l2, respectively, as practical.

Various changes and modications in the construction herein illustrated and described 'may be made without departing from the scope of the invention as defined in the claims.

What I claim is:

1. In a smoking pipe, a bowl having a stem connected at one end thereto, said stem'an-d bowl having a lower longitudinal passage extending from a point closely adjacent to the front of the bowl and beneath the bottom of the latter and through the opposite end of the stem, and said stem having an upper longitudinal passage communicating at one end with the interior of the bowl and having its opposite end extending through the opposite end of the stem, a partition extending longitudinally of the stem and separating said passages, a removable absorbent member in the lower passage extending beneath the bowl bottom and terminating adjacent to the said opposite end of the lower passage, a closure for said opposite end lof the lower passage, a bit having a part of its inner end disposed pver and abutting the closure to conceal the latter and having-a second part extending beyond said iirst named part of the inner end of the bit and into said opposite end of the upper passage, said partition having a pair of spaced openings adjacent the rear o1 the bowl and the opposite end of the stem respectively lto establish communication between the passages.

2. A smoking pipe in accordance with claim 1, wherein the under side of the stem is formed with an opening extending into the lower passage and located between said pair of openings, and wherein there is a closure for said opening vin the under side of the stem.

3. A smoking pipe in accordance with claim l, wherein the closure is threadedinto the opposite 'end of the lower passage and has a substantially flat outer face against which said iirst named part of the inner end of the bit seats.

ROMEO J. BERGERON.
