Improvements in Tobacco Pipes.
I, GEORGE HENRY THOMSON, of 14, Remus Road, North Bow, London, E.
Gentleman, 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 :-
My invention relates to improvements in tobacco pipes and has for its object
to provide a cool and dry smoking pipe and one that will prevent the absorption
of nicotine by the user, thus rendering smoking far less injurious than where a
pipe of the ordinary description is employed, while it is so constructed and
arranged that the various parts can be easily taken to pieces, thoroughly cleaned,
and put together again in a short space of time.
My improved pipe consists of a suitably shaped bowl furnished near the bottom
with a hole or perforation passing through same, from side to side, and within
which is contained one end of the stem, which is formed of wood or other suitable
material, and has a passage passing completely through from end to end of same,
while at the free end, which is of increased size, a second and smaller passage
is formed starting a short distance above the first mentioned passage and gradually
curving down until it opens into it at a short distance from the free end of the stem.
The mouth-piece is constructed of horn, vulcanite, amber or other suitable
material and is furnished with the usual passage for the smoke, which passage
or channel is connected with the second or smaller channel in the stem by means
of a short length of tubing which is partly contained within one passage, the
remaining part being pushed into the other passage when putting the pipe together.
The end of the mouth-piece is likewise increased in size so as to correspond with
the increased size of stem at this point, and is further furnished with a short
projecting plug which closes the first mentioned or main passage in the stem at this
end when the mouthpiece is in position, the other end being closed by means of a
loose plug which can be removed when necessary.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a side elevation of the pipe and Fig. 2 a longitudinal section through
same.
Fig. 3 is a view of the bowl and one end of the stem with mouth-piece removed
and Fig. 4 is an end view of the mouthpiece.
The bowl is furnished with a hole or perforation through which one end of
the stems is passed. The stem is formed with a longitudinal passage or channel p
and a second and smaller passage p¹ which is connected by means of the tube t
to the passage or channel in the mouth-piece m. The mouth-piece m is further
formed with a small plug 9 which closes one end of the passage p while the other
end is closed by the removable plug a and a small hole h is provided to connect
the bowl b with the stem 8.
I
The action of my improved pipe is as follows:
The smoke having been drawn into the passage p it can only escape by means of
the passage p' to the corresponding passage p2 in the mouth-piece m the passage p
being closed by the plugs a and g. By this means the whole of the nicotine,
moisture etc. is collected and contained within the said passage p.
In order to clean the pipe, when necessary, the mouth-piece m and plug a are
removed thus opening the passage p at both ends and allowing it to be easily

page_text: and thoroughly cleaned, the mouth piece and smaller passage being cleaned in the
ordinary manner.
My improved pipe may be constructed in any suitable shape, that shown in the
drawings being merely used for the purpose of illustration, and may be constructed
of materials most suitable for the purpose.
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. The improved pipe consisting of the bowl b, stems having passages p p²,
mouth-piece m with passage p' and plug 9, and plug a, substantially as herein
described and for the purposes specified.
2. In a pipe such as above claimed the combination of the passages, p, p¹ and the
continuation passage p² with plugs a and g substantially as described and for the
purposes specified.
3. The new or improved pipe arranged and constructed substantially as herein
described and shown and for the purposes specified.
