I, LEON BRÜLE, of 27, Rue de l'Hopital, Brussels, in the Kingdom of Belgium,
Manufacturer, do hereby declare the nature of this invention to be as follows:.
This invention has for its object an important improvement in the construc-
tion of tobacco-pipes and more particularly with reference to the construction
of the suction channel situated between the bowl and the mouth piece of the'
pipe, whereby the hygienic conditions of the pipe are considerably increased
owing to the particular arrangement of the channel and especially to the facility
of cleaning the pipe.
Contrary to ordinary arrangements in which the channel was bored direct into
the stem of the pipe and abutting in the bowl while the other end thereof con-
tinued into the mouth piece, in my improved arrangement the channel is formed
in the perimeter of a plug fitting the length of the stem which is suitably bored
and forms the outer closing wall to the channel through its entire length.
This construction permits of giving the channel any desired form, straight or
curved, the extremities of which lead on the one hand into the opening of the
bowl and on the other hand into the central opening of the mouth piece. Owing
to the facility thus secured for the construction of the channel I prefer to form
it as a helix around the plug and with its extremities leading into the bowl and
the mouth-piece either direct or through two narrow passages formed in the
plug. In this manner the channel may have any desired length according to
the number of convolutions given to the helical groove, thus cooling the smoke
and freeing it from nicotine to any desirable degree.
The mouth piece is fixed to the plug by a screwed end and thus the latter
may be easily withdrawn from the stem for cleaning purposes, the cleaning
being facilitated by the sharp edges of the convolutions scraping off all the
deposition and removing it from the stem which may then be finally wiped by
the aid of a sponge or paper wiper which is rendered easy by the large diameter
of the bore. The plug may be wiped with a piece of paper or rag so as to con-
stantly keep the pipe in a clean condition without the slightest difficulty.
Instead of inserting the plug direct into the stem the stem may be lined with
a tubular sleeve of ebonite or other appropriate material and the plug then
inserted into this latter, this arrangement presents advantages which will be
readily appreciated by manufacturers of special articles for smokers.

page_text: I, LEON BRÜLE, of 27, Rue de l'Hopital, Brussels, in the Kingdom of Belgium,
Manufacturer, 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 has for its object an important improvement in the construc-
tion of tobacco-pipes, and more particularly with reference to the construction
of the suction channel situated between the bowl and the mouth-piece of the
pipe, whereby the hygienic conditions of the pipe are considerably increased,
owing to the particular arrangement of the channel, and especially to the facility
of cleaning the pipe.
My invention will be readily understood by reference to the accompanying
drawing of which Figures 1 and 2 show in central longitudinal section two
slightly different arrangements in accordance therewith.
Contrary to ordinary arrangements, in which the channel is bored direct into
the stem of the pipe and abuts into the bowl, while the other end thereof is
continued into the mouth piece; in my improved arrangement the channel a
is formed in the periphery of a plug 6 fitting the length of the stem c which
is suitably bored and forms the outer closing wall to the channel through its
entire length. This construction permits of giving the channel any desired
form, straight or curved, the extremities of which lead on the one hand into the
opening of the bowl and on the other hand into the central opening of the
mouth piece. Owing to the facility thus secured for the construction of the
channel I prefer to form it as a helix around the plug b as shown in the drawing
and with its extremities leading into the bowl and the mouthpiece either direct
or through two narrow passages e e formed in the plug b. In this manner the
channel a may have any desired length according to the number of convolutions
given to the helical groove, thus cooling the smoke and freeing it from nicotine
to any desired degree.
The mouth piece f is fixed to the plug 6 by a screwed end, and thus the latter
may be easily withdrawn from the stem c for cleaning purposes, the cleaning
being facilitated by the sharp edges of the convolutions scraping-off all the
deposition and removing it from the stem c which may then be finally wiped
by the aid of a sponge or paper wiper, which operation is rendered easy owing
to the large diameter of the bore. The plug may be wiped with a piece of paper
or rag so as to constantly keep the pipe in a clean condition without the slightest
difficulty.
Instead of inserting the plug 6 direct into the stem e as is shown in Figure 2,
where the helical groove is shown in elevation, the stem may be lined with a
tubular sleeve 9 of ebonite or other appropriate material, and the plug then
inserted into this latter as shown in Figure 1 where the groove is shown in
section, this arrangement presents advantages which will be readily appreciated
by manufacturers of special articles for smokers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:--
A tobacco pipe having a suction-channel of special construction, characterized

page_text: by the said channel being formed in the periphery of a plug which is fitted
into the stem of the pipe, said stem being lined or not as desired with an internal
sleeve.
