COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, ALLAN FREEMAN VOLK, a citizen of the United States, residing at 412 West
16th Street, of New York in the County of New York, and State of New York,
U.S.A. Engineer, do hereby declare the nature of this invention, 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 pipes, and the object thereof is to provide a pipe having
improved means for cleaning the stem thereof and for preventing the fouling of the
stem and pipes.
The invention is fully disclosed in the following specification of which the
accompanying drawing forms a part which represents a central vertical section of a
pipe and the stem thereof provided with my improvement.
In the practice of my invention I provide a bowl A, of the pipe, which may be
of any desired form with the usual stem B.
The stem B is provided with a central bore C, which is in communication with
the bowl of the pipe by means of a passage D, formed in the bottom thereof and
said central bore of the stem and the passage D are also in communication with a
longitudinal bore E, formed in the back lower portion of the bowl which is adapted
to be closed by a screw plug F.
Connected with the end of the stem B, is a mouth piece G, which is to enlarge
at its inner end as shown at H, and formed therein is a cavity or chamber K.
Within the central bore C, of the stem is placed a tube, L, the outer end of
which projects into the chamber or cavity K, and formed in the upper side thereof
is a perforation M, and the inner end of said tube L, is inclined as shown at N,
and adapted to abut against a shoulder formed at the end of the central bore C,
and formed in the inclined of the tube L, is a port or opening O.
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawing. The mouth piece C, is
connected with the stem B, by means of a screw thread and is removable therefrom
and the tube L, may also be removed when desired. In use the cavity or
chamber K, will receive any fluid substance from the mouth and the same will be
prevented from entering the tube L, by reason of the fact that the perforation M,
is in the upper side thereof and all ashes or other substances which may pass
through the passage D, in the bowl A, will be received in the bore or opening E,
and will be removed therefrom by removing the screw threaded plug F. As thus
formed it will be practically impossible for any nicotine or other substances to enter
the tube L; if in use however, any substances of any kind should enter said tube L,
the same may be easily cleaned by removing the mouth piece and withdrawing said
tube and will also be seen that the entire stem, the mouth piece and the bowl of
the pipe together with the passages E, and D, may be thoroughly cleaned in this
operation.
My invention is not limited in the exact form, construction and arrangement of
the various parts thereof as herein shown and described and I therefore reserve
the right to make all such alteration therein as fairly come within the scope of my
invention.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A pipe, provided with a stem and a removable mouth piece, the bore of the
stem being in communication with the bowl of the pipe and with a passage which
opens at the rear lower side of the bowl, and the inner end of the mouth piece
being provided with an enlarged cavity of chamber, substantially as shown and
described.
2. A pipe, provided with a stem and a removable mouth piece, the bore of the
stem being in communication with the bowl of the pipe and with a passage which
opens at the rear lower side of the bowl, and the inner end of the mouthpiece being
provided with an enlarged cavity or chamber, and the central bore of the stem
being provided with a tube the outer end of which projects into the cavity or
chamber in the mouth piece, and is provided with a perforation in its upper side
and the inner end of which is provided with a port or opening which communicates
with the passage in the bottom of the bowl, substantially as shown and described.
3. The combination with a pipe, provided with the usual stem, a removable
mouth piece, a tube as L, located in the bore or stem, the outer end of which
projects into a chamber or cavity formed in the inner end of the mouth piece, and
is provided with a perforation in its upper side and the inner end of which is
inclined and provided with a port or opening which communicates with the passage
in the bottom of the bowl, said bore of the stem being also in communication with
a passage which opens at the outer lower side of the bowl, substantially as shown
and described.
