5 Claims. (Cl. 131-12)
The smoking pipe, according to this invention,
This invention relates to new and useful im
provements in a cool smoking pipe.
The invention has for an object the construc
tion of a smoking pipe which is characterized by
a pipe stemwith a novel construction which pro
U
duces a cool smoke when the pipe is used.
More speci?cally, the invention contemplates
an arrangement of a pipe stem formed of sec
tions, one connected with the bowl and the other
10 with the mouthpiece of the pipe stem. It is pro
posed to arrange the junction between these sec
tions in a particular manner.
‘ It is proposed to provide inter-engaging por
tions on the adjacent ends of the pipe sections
and to arrange longitudinal recesses along the
sides of one of the sections, ‘and communicating
with radial recesses connecting with a passage
for the smoke through the mouthpiece. When
the smoke is caused to travel through this path
it will be relatively dry and cool.
Still further the invention proposes to provide
an element rotative on a reduced portion of the
mouthpiece stem section which is to be formed
with V-shaped passages connecting with a main
smoke passage, to provide longitudinal passages
in the outer face of said element connecting with
radial passages aligned with portions of said V
shaped passages and to provide anarrangement
whereby the element may‘ be held in various
turned positions to control the alignment of the
radial passages with the V-shaped passages and
thus the passage of smoke.
For further comprehension of the invention,
and of the objects and advantages thereof, ref
erence will be had to the following description
and accompanying drawing, and to the appended
claims in which the various novel features of the
410
comprises a pipe bowl I0 connected with a bowl
stem section l I formed with a passage l2 for the
smoke. The bore of the pipe bowl ii! is formed
with a substantially flat bottom 13. There is a
small aperture M in one side of the bottom l3
which connects with the bottom of the passage
l2, which is relatively much larger in size than
the opening M. A mouthpiece stem section it»
supports an element It which is engageable into ll)
the end of the passage l2 for connecting the sec
tions together. The element Iii may be rotative
upon a reduced portion l5a of the mouthpiece
stem section Hi. This reduced portion I 5a is
formed with V-shaped passages ll connecting 15
with a main smoke passage 28 which is preferably
round in cross section, and extends through the
mouthpiece stem section. The V-shaped pas
sages H are arranged circumferentially on the,
peripheral surface of the reduced portion Isa.
Longitudinal passages is are formed on the
outer face of they element it below the center of
said element and connect with radial passages ill
aligning with portions of the V~shaped passages
H. A means is provided for holding the ele
ment iii in various rotative positions to control
the alignment of the radial passages l9 with the
V-shaped passages ll. The full lines in Fig. 5 I
show relative positions of these parts in which
the passage is completely unrestricted. The dot
and dash circles I9’ indicate different positions
of the passages ii) in which there is some restric
tion. It should be noted that the element It
may be turned to various positions to produce
various different sizes of passages for the smoke.
invention are more particularly set forth.
In the accompanying drawing forming a ma
The means for holding the element l'? in var
ious rotative positions includes a resilient ele
ment such as a‘ spring 20 which is coaxially ar
ranged upon the reduced portion llia and which
terial part of this disclosure:
acts against a shoulder 16*3L formed in the reduced ”
Fig. 1 is a transverse sectional view of a pipe
constructed according to this invention, a por
portion 16. The spring 20 also acts against a
?ange 2| which is ?xedly mounted upon the outer
end of the reduced portion l?a. A plug 22 closes
the inner end of the passage l8 so that the smoke
is forced to pass through the longitudinal pas
sages l8 through the radial passages l9 and then
through the main smoke passage 28 formed in
the mouthpiece stem section Hi. The spring 20
urges the element I6 so that an end portion I6b
engages against a portion of a shoulder I5b formed
tion thereof being shown in side elevation.

stem section per se.
Fig. 3 is a transverse sectional view of a por
tion of the mouthpiece stem section, this section
being taken on the line 3-3 of Fig. 1.

taken on the line 4-4 of Fig. 2.

on the mouthpiece stem section I5.
These en~
gaging surfaces may be roughened or serrated
so that they readily maintain relative positions.
In Fig. 6 another embodiment of the invention
2
2,122,255
has been disclosed in which the mouthpiece stem
15' and the reduced portion I 5% are separate
pieces connected by a threaded portion l5". In
other respects this form. of the invention is simi
lar to the previous form and similar parts may
be recognized by the same reference numerals.
The operation of the device is as follows:—
When smoke is drawn through the mouthpiece
it will travel from the pipe bowl l0 through the
10
passage Hi, the passage l2, the longitudinal pas
sages l8, the radial passage l9, and the passage
28 to the smoker’s mouth. The element l6 may
be turned relative to the mouthpiece I 5 for a dual
purpose. First, to control the alignment of the
passages “5 with the passages l1, and thus the
passage of smoke. Then again, the element It
may be turned to different positions to change the
relative positions of the longitudinal passages l8
to the base of the passage l2. This will control to
some degree the amount of moisture permitted to
pass through the pipe stem.
It is to be understood that this invention may
be used in connection with all types of smoking
pipes, irrespective of their shapes or material
1' they are made of.
While I have illustrated and described the pre
ferred embodiments of my invention, it is to be
understood that I do not limit myself to the pre
cise constructions herein disclosed and the right
is reserved to all changes and modi?cations com
ing within the scope of the invention as de?ned
in the appended claims.

claim as new, and desire to secure by United
States Letters Patent is:—
