Improvements in Tobacco Pipes or the like.
A communication by JOSEPH LAUHOFF, of Detroit, in the County of Wayne and
State of Michigan, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors 6, Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to tobacco pipes and consists of the devices and appliances
hereinafter specified and claimed.
The invention is designed particularly to provide a pipe adapted to remove the
nicotine and separate it from the smoke before the smoke passes therefrom, thereby
overcoming the deleterious effects thereof.
In the accompanying drawings-
Figure 1 is a vertical longitudinal section, and
Figure 2 a separate view of the passage ².
In carrying out the invention, A represents the main pipe bowl, the same being
preferably provided with an interior metallic bowl or shell A' removable therefrom,
and forming the base of the completed bowl, as shown at A2, said base being
provided with a passage a therethrough. The lower end of the bowl A is screw
threaded as shown at a'. The interior bowl A¹ it will be observed is of the nature
and form of a cartridge shell. A³ is a perforated cap for the bowls A, A.
.
B is an intermediate pipe section constructed to have a screw threaded engage-
ment with the bowl A. as shown at b. The outer end of said section is provided
with a wall through which is led a passage arranged to communicate with the
passage a in the interior bowl A' when united to the bowl A. The opposite end of
the section B is constructed with a chamber B¹, the wall of which is suitably
screw threaded as shown at 3. The end of the passage is preferably extended
from the wall & into said chamber, as shown.
C is an additional section or stem of the pipe screw threaded as shown at c to
engage with the section B. The forward or outer end of said stem is constructed
with a chamber C₁ communicating with the chamber B' when the parts B and C
are united. The stem C is provided with a passage e' projecting forward into the
chamber C as shown.
It will be seen that the chamber BI C₁ forms an intercepting smoke chamber, and
one in which nicotine may readily be deposited, since the smoke passing into said
chamber first fills the chamber instead of passing continuously and uninterruptedly
into the passage el, a space being left between the adjacent terminals of the
passages, e. Nor does the smoke pass into the passage e' from the extremity of
the chamber C, in which case there would be liability of the nicotine being drawn
into said passage e. But, inasmuch as the smoke must enter from the forwardly
projected end of said passage, this liability is overcome.
The present invention is not limited to any particular material from which the
various parts above enumerated shall be constructed, but the bowl A and
sections B C may be constructed of wood, while the inner bowl A' and the
passages and e' may be made of metal. The section C may be shaped as desired
to constitute, or connect with, a mouth piece. To still further facilitate the removal
of the nicotine from the smoke in its passage through the chamber B¹ C¹, the
invention contemplates such a formation of the passage as to spread the smoke
emerging therefrom into said chamber. Accordingly it is preferred to construct
Di 11

page_text: the projecting end of said passage with a closed end as shown at b³ the passage
being formed with lateral openings through which the smoke must pass into the
chamber B C', the smoke being spread laterally into said chamber as it enters the
same. This will effectually throw off the nicotine to the sides of said chamber,
and free the smoke therefrom in its further course through the passage el. As shown,
the stem C extends in a direction longitudinal to the bowl, but the invention is not
limited thereto.
It is evident that the device might be used as an inhaler as well as a tobacco pipe
and the invention contemplates both.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to he performed, as communicated to me
by my foreign correspondent, I declare that what I claim is-
1. A tobacco pipe consisting of a bowl A and shell A provided with a passage
through its base, an intermediate section B and stem C each provided with smoke
passages and forming an intercepting chamber B¹ C', substantially as described.
2. A pipe consisting of a bowl, an intermediate section, a stem removably
engaged with the intermediate section and forming an intersecting chamber B¹ C₁,
tubes forming smoke passages in said bowl, section and stem, the tube in the inter-
mediate section projecting into said chamber and formed with lateral openings to
spread the smoke in said chamber, substantially as described.
3. A pipe consisting of a bowl, a communicating intermediate section, a com-
municating stem forming with said section an intercepting chamber B'C', said
intermediate section provided with a passage 2 closed at its outer extremity in said
chamber and provided with lateral openings to spread the smoke, the communicating
tube in the stem projecting forward into said chamber, substantially as described.
4. A pipe consisting of a bowl A, an interior shell A closing the base of the
bowl A, a perforated cap closing said bowl, a communicating intermediate section
removably connected with said bowl, a communicating stem removably connected
with the intermediate section, an intercepting chamber formed by said section and
stem, said section and stem each provided with tubes forming smoke passages
projecting toward each other in said chamber, substantially as described.
