PROVISIONAL SPECIFICATION.
Improvements in Tobacco-pipes.
I, EMILE VUILLARD of Saint Claude (Jura), in the Republic of France, do
hereby declare the nature of this invention to be as follows:-
Within
This invention relates to tobacco pipes with straight stems and consists in making
such pipes of three main parts tightly fitted to each other by frictional contact or
otherwise. This pipe is mainly characterized by the provision of a channel or
passage for suction, situated above the nicotine chamber or reservoir in the
longitudinal direction so that one end of it is connected with the bowl-end the other
terminates near the open end of the portion of the stem next to the bowl.
this comparatively wide portion of the shank or stem forming the nicotine-collecting
chamber is fitted the mouth-piece constituting the real stem of the pipe and having
a longitudinal axial channel as usual. Within the portion of this stem or mouth-
piece which fits into the nicotine reservoir is tightly fitted a small slightly tapered
tube made of bone, ivory, horn, wood or any other suitable material which tube may
be termed the "isolator." It will be seen that the suction openings or passages
are entirely independent of each other in this type of tobacco pipe i.e. they never
coincide or form a continuation of each other, so that the smoke in flowing towards
the mouth follows a sinuous course.

COMPLETE SPECIFICATION.
Improvements in Tobacco-pipes.
I, EMILE VUILLARD of Saint Claude, (Jura), in the Republic of France,
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 tobacco-pipes with straight stems and consists in making
such pipes of three main parts tightly fitted to each other by frictional contact
or otherwise. This pipe is mainly characterized by the provision of a channel or
passage for suction, situated above the nicotine chamber or reservoir in the
longitudinal direction, so that one end of it is connected with the bowl and the
other terminates near the open end of the portion of the stem next to the bowl.
Within this comparatively wide portion of the shank or stem forming the nicotine-
collecting chamber is fitted the mouth-piece constituting the real stem of the pipe,
and having a longitudinal axial channel as usual. Within the portion of this
stem or mouthpiece which fits into the nicotine reservoir and the extension of the
air or suction opening, is tightly fitted or screwed a small preferably slightly
tapered tube provided with helical grooves on its periphery and made of bone,
ivory, horn, wood, or other suitable damp-proof material, which tube may be
termed the "isolator." It will be seen that the suction openings or passages are
entirely independent of each other in this type of tobacco pipe i.e. they never coincide
or form a continuation of each other, so that the smoke in flowing towards the
mouth follows a sinuous course.
In the accompanying drawings,-
Fig. 1 is a longitudinal section through the axis of the improved pipe and Fig. 2

page_text: Like letters indicate like parts throughout the drawings.
The bowl a of the pipe is connected with the part 6 of the stem by a suction
channel e formed above the nicotine reservoir d provided in the part b
immediately adjoining the bowl a.
Within the open end of the pipe is fitted or wedged the other part of the stem
or mouth-piece c. The suction opening / provided in this mouthpiece c is extended
through the nicotine reservoir d, the channel g provided in the centre of an isolating
tube screwed into the mouth-piece forming its continuation.
The isolating tube is provided with one or more spiral ribs on its periphery
so as to cool the smoke issuing from the bowl a and passing through the channel e
into the nicotine reservoir d whence it is conducted through the opening o into the
isolating tube through which and through the channel it at last reaches the
mouth of the smoker.
The isolating tube ƒ may be made of bone, ivory, born, wood, or any other
damp-proof material and either cylindrical taper or other form.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,―
1. A tobacco pipe provided with a suction channel e above and throughout the
length of a nicotine reservoir d and an isolating tube such as provided externally
with one or more spiral ribs the said tube being fitted to the stem or mouth-
piece of the pipe and entering the nicotine reservoir d all substantially as
described and illustrated in the accompanying drawings.
2. The combination and arrangement of parts constituting the complete tobacco
pipe substantially as described and illustrated in the accompanying drawings.
