`
This invention relates to `new and useful im
provements in a nicotine separating cool smoke
pipe stem.
`'I'he invention'has for an object the construc
5 tion of a pipe Vstem which is characterized by a
liquid collecting passage extending from its in
ner end: to an intermediate point and there join
ing 1‘with 4a vent passage terminating in the top
side `of the pipe stem, said vent passagebeing
associated with a smoke passage extending from
the lnear end of the stem to its outer end and lo
cated above the liquid collecting passage. When
the pipe stem is thus constructed it is possible to
draw smoke through the smoke passage without
15 being annoyed with the simultaneous passage of
the juices from the tobacco. Furthermore, it is
sage and extending through said vent passage I3.
The operation of the device is as follows:
The pipe is supported in one’s mouth by en
gagingv the mouthpiece between one’s teeth.
When the smoker draws in, the smoke from the 5
tobacco will pass through the passage I4 into
the smoker’s mouth. If there is any juice, some
of the juices from the tobacco will collect in the
bottom of the bowl and pass directly into the
liquid collecting passage I2. Other of the juices 0
will pass through the inner end portion of the
smoke passage I4 until they reach the vent pas
sage I3 and then will move down the vent pas
possible to draw in air which mixes with the
sage and collect in the liquid collecting passage
I2. Air from the exterior will enter the vent
passage I3 and temper the temperature of the
smoke.
smoke so as to cool the smoke.
Still further the invention embodies an ar
entering the passage I3 merely by holding a fin
20 rangement in which one’s finger may control the
amount of air passing through the vent opening
and so control the temperature of the smoke
drawn through the smoking passage.
A further object of the invention resides in the
provision of a means for closing the vent to Var
ious degrees and so eliminate the necessity of
manually holding the vent closed with one’s fin
ger.
For further comprehension of the invention,
and of the objects and advantages thereof, refer
ence will be had to the following description and
accompanying drawing, and to the appended
claims in which the various novel features of
the invention are more particularly set forth.
In the- accompanying drawing l.forming a ma
terial part of this disclosure:
Fig. 1 is a perspective view of a pipe with a
stem constructed according to this invention.
Fig. 2 is a transverse sectional view taken on
the line 3_3 of Fig. 4.
Fig. 3 is a plan View of the pipe shown in Fig. 1.
Fig. 4 is a sectional View taken on the line 4--4
of Fig. 3.

The smoke pipe stem, according to this inven
tion, comprises material in the form of a stem
I 0 having a mouthpiece portion Ill]a at its outer
end, and a reduced portion Iûb at its inner end for
engaging into an opening in a pipe bowl such as
the bowl I l. The pipe stem II] has a liquid collect
50 ing passage I2 extending from its inner end to an
intermediate point I2’ and there joining with a
vent passage I3 terminating in the top side of the
pipe stem. 'I‘he pipe stem also has a smoke pas
sage I4 extending from its inner end to its outer
end and located above said liquid collecting pas
The smoker may control the amount of air
ger completely or partially over the outer end 20
of the vent opening, when the light in the pipe
bowl is low, to start burning the tobacco.
The pipe is provided with an arrangement for
mechanically controlling the air passing through
the vent passage I3. The arrangement comprises
a shutter element I6 slidably mounted in a pas
sage Il formed in the pipe stem. The shutter
I G connects with a stem I6a which passes through
a fixedly mounted bearing disc I8 mounted in the
passage I'I. A collar I9 is ñxed on the stem 16a. 30
A spring 20 is arranged coaxially on the stem |69'
and acts between the collar I9 and the disc> I8
for normally urging the stem I6a into an ex
tended position. The extremity of the stem Isa,
indicated by the numeral |6113, extends from the 35
inner shoulder of the stem I0, which shoulder is
produced by the reduced portion IIlb, and extends
into a cam shaped recess 2I formed in the ad
jacent shoulder of the pipe bowl. Normally, the
parts are in the position shown in the figures of
the drawing. The passage I3 is then unre
stricted.
If it is desired to partially close the passage I3
it is merely necessary to slightly turn the bowl
of the pipe relative to the stem. The cam shaped
recess ZI will then press in the stem Ilia against
the extending action of the spring 20 and the
shutter I6 will extend partially or completely
across the vent passage I3, depending merely
upon the relative position` of the cam recess 2| ‘
and the extended end Iiiea of the stem.
It is to be understood that the stem may be
moulded, hand curved and the holes drilled, or
made in any other suitable manner with one or
more pieces of suitable material.

While I have illustrated and described the
preferred embodiment of my invention, it is to
be understood that I do not limit myself to the
precise construction herein disclosed and the
right is reserved to all‘changes and modiñcations
coming Within the scope of the invention as de
iîned in the appended claims.
Having thus described my invention, what I
claim as new, and desire to secure by United
States Letters Patent isz
1. A nicotine separating cool smoke pipe stem,
comprising material in the form of a pipe stem
`and having a mouthpiece portion at its outer end
and a reduced portion at its inner end for en
comprising material in the form of a pipe stem
having one of its ends reduced forming a shoul~
der portion, said pipe stem having a liquid col
lecting passage extending from its inner end to
an intermediate point of said stem and there
joining with a vent passage in the top side of
said pipe stern, said pipe stem also having a smoke
passage extending from its inner end to its outer
end and located above said liquid passage and
extending through said vent passage, a pipe bowl
for said stem having an opening engaging said re
duced end and a cam recess formed in the face of
said pipe bowl abutting said shoulder portion, a
shutter element slidably mounted in a passage
f_ormed transversely across the vent passage, a
stem formed on said shutter element and having
from its inner end to an intermediate point of ‘an extended end engaging said cam recess, a
said stem and there joining with a vent passage bearing disc ñxedly mounted in the passage hous
gaging into an opening in a pipe bowl, said pipe'
stem having a liquid collecting passage extending
terminating in the top side of said pipe stem, said
pipe stem also having a smoke passageex-tend
ing from its inner end to its outer end` and located
above said liquid collecting passage and extend
ing said stemvand having an opening through
which said stem passes, a collar formed on said 20
stemlon the side of said disc opposite said shut
vent passage, comprising a Vshutter element in a
passage transversely across thev vent passage, a
ter element, and a spring on said stem operating
between said' disc and said collar to normally urge
the extended end of said stem against said cam
recesses, whereby said pipe bowl may be turned
slightly with relation to said stem to cause said
stem connected with the shutter element and
extended end to be forced inward against the
4ing through saidvent passage, and mechanical
means for partially or completely closing said
having an extended end engaging a cam recess
in a pipe bowl for said stem, a pipe bowl for said
30 stem having said recess, and resilient means urg
ing s'aid stem against said cam recess.
2. A nicotine separating cool smoke pipe stem,
normal action of said spring to force said shut
ter element across the vent passage to partially
or entirely close said vent passage.
