SMOKING PIPE Filed April 5, 1937 I N VEN TOR.

ATTORNEYJ.

Patented Nov. 2, 1937 l" oNir-En'sTTEs parte PATENT- orifice 3 Claims.

The object of my invention is to produce a smoking pipe, of simple, relatively inexpensive construction which will retain within itself, such moisture as is generated as a result of the burning of the tobacco, and as is injected thereinto assaliva by the smoken'in such manner as to practically prevent nicotine-contaminated liquid from passing into the mouth of the smoker.

The accompanying drawing is a slightly magnified section longitudinally of the stem, and illustrates embodiments of my invention:

Fig. 1 is a section of a straight stem pipe; and

Fig. 2 a section of a drop stem pipe.

In the drawing I0 and II indicate, respectively,

the bowl and integral stem of a pipe. The outer end of the stem is counterbored at I2 to receive the ensmalled end I3 of supplemental stem, or bit I4. Stem II is bored, at I5, from the bottom of the counterbore into the bowl and within this bore I5 is mounted, conveniently permanently, a tightly fitting metal tube I6 the outer end of which is spaced from the inner end of end I3 of stem I4, and the inner end of which preferably extends to the axis of the bowl.

Immediately below bore I5, stem II is bored at I1, to form a cul-de-sac, or closed-end pocket, for the removable reception of the closed inner end of metal tube I8 which is mounted in bore I9 which extends axially through stem I3-I4,

the outer end of tube I8 preferably extending close to the mouth end of bore I9. The inner end of bore I9 is enlarged at I9 over the top of tube I8 and registering with this counterbore is a perforation 20 through the upper part I of tube I8 into the interior thereof, thus dividing tube I8 into a blind pocket or reservoir end R and a smoke -outlet end C.

The position of perforation 20 depends somewhat upon the distance between the bowl and the mouth end of stem I4, but in any event Vit should be spaced from the outer end of tube I6 (or bore I5)- so that any saliva entering tube I8 in quantities suflicient at any one time to ll the diameter of the bore of said tube, and thus having a tendency to flow outwardly through the perforation 20, may sink into the `inner end of the counterbore I2. In use, moisture rarely gathers in this counterbore. should be far enough away from the outer end of tube I8 to insure condensation of moisture from the smoke at an effective distance from the mouth so as to permit the condensate to flow back intoI reservoir R rather than to be sucked into the users mouth, having in mind the fact that the farther away perforation 20 is from the sealed in- Perforation 20 ner end of tube I8, the greater will be the capacity of reservoir R. I believe that, in a pipe of the rrelative portions shown in the drawing, perforation 20 may be effectively placed about midway between the bowl and the mouth end of stem I3--I4. The bore of tube I8 should be large enough to receive an ordinary pipe-cleaner swab.

In use, the smoke is drawn from the outer end of tube I6, enters tube I8 through perforation 20 and passes into the mouth of the user. Conden- 10 sation from the Smoke occurs adjacent perforation 20, mostly within tube I8 and flows into the blind-end reservoir end R of said tube. Saliva entering tube I8 will trickle into said reservoir end R. and, because of the gap between perfora- 15 tion 20 and the outer end of tube I6, will not pass through 20 so as to produce frying in the bowl.

As a rather profuse wet smoker, I have found, in an extended use of a pipe constructed as de- 20 scribed above, that a perfectly dry, cool smoke is afforded and that no nicotine-contaminated liquid enters the mouth.

After use tube I8 may be readily freed of liquid either by a snappy shaking of the pipe with 25 stem inverted, in a manner well known to smokers, or by swabbing with a cleaner, either with or without separation of stem I3-I4 from the bowl, and tube I6 may be readily swabbed upon removal of stem I3--I4, tube I8 lying loosely in 30 bore I1 and coming out with stem I3-I4.

Any slug of liquid in reservoir R cannot be sucked from the reservoir because of the intermediate perforation 20 and the closed inner end of tube I8. 35

I claim as my invention:

1. A smoking pipe comprising a bowl and separable bored stem, a metal tube mounted in the bore of the stem and having a closed inner end and a perforation through its top side intermediate its open end and its inner closed end with a substantial length of said closed end lying within a blind pocket formed in the main body of the pipe, a comparatively short nicotine pocket surrounding said tube between the bowl and said perforation, the upper region of said nicotine pocket communicating respectively with the bowl and the said perforation.

2. A smoking pipe comprising a bowl and bored v stem, a metal tube mounted in the bore of the stem having a closed inner end and a perforation through its top side intermediate its outer open end and its inner closed end, a substantial length of said closed end lying within a blind pocket formed in the main body of the pipe, a

Cil

comparatively short nicotine pocket surrounding said tube within the main body of the pipe at a point intermediate its closed end and said perioration, a smoke conduit leading from the bowl 'to the bowl end of the upper region of said pocket,

and a second smoke conduit leading from the upper region of the bit end of said pocket to Said perforation.

3. A smoking pipe comprising a bowl and bored stem, a metal tube mounted in the bore of the stem having a closed inner end and a perforation and a metal tube in said Erst-mentioned conduit. 10
