PROVISIONAL SPECIFICATION.
Improvements in Tobacco-pipes.
I, ADOLPHE GROS of Saint-Claude, Jura, in the Republic of France, Pipe
Manufacturer do hereby declare the nature of this invention to be as follows:-
The invention relates to means or apparatus in the stem of a tobacco pipe which
prevents the nicotine from rising into the mouth of the sinoker.
By the aid of the accompanying drawing my invention will be well understood.
Figure 1 is a longitudinal section of a curved pipe constructed according to my
invention and Figure 2 is an exterior view of the same.
As represented in the drawings the end of the pipe stem a has an insulating tube b
screwed into it which extends a certain distance into the reservoir c intended to
receive the nicotine.
This tube has a sort of piston d near its centre, with an india-rubber washer e
making a hermetic joint against a shoulder f formed in the reservoir which can be
made of india-rubber or other suitable material.
The nicotine reservoir e is of less diameter at its front part than the space formed
in the stem of the pipe to allow the smoke to pass which latter enters by an
aperture g and then passes into the tube by a second aperture in order to he
inhaled through the mouth-piece. {
This arrangement prevents the nicotine from returning into the bowl of the pipe
or from getting into the mouth-piece.
The pipe can be easily cleaned, for the mouth-piece a and the reservoir c can be
readily removed from the stem of the pipe. This reservoir can also be separated in
its turn by unscrewing it from the insulating tube.
In the drawing I have represented a curved pipe but it will be well understood
that the invention can also be applied to a straight pipe of any appropriate material
and dimensions.
The mounting can also be made either to screw or slide on.

COMPLETE SPECIFICATION.
Improvements in Tobacco-pipes.
I, ADOLPHE GROS, of Saint-Claude, Jura, in the Republic of France, Pipe
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 :-
The invention relates to means or apparatus in the stem of a pipe which prevents
the nicotine from rising into the mouth of the smoker.
By the aid of the accompanying drawing my invention will be well understood.
Figure 1 is a longitudinal section of a curved pipe constructed according to my
invention, and Figure 2 is a section of a straight pipe, but representing the parts
detached.
As represented in the drawing, the inner end of the pipe stem a has an insulating
C intended
tube screwed into it, which extends a certain distance into the reservoir
to receive the nicotine.
This tube b has a sort of piston d near its centre, with an india-rubber washer e,

page_text: making a hermetic joint against a shoulder formed in the reservoir, which can be
made of india-rubber or other suitable material.
The nicotine reservoir c is of. less diameter at its front part than the space formed
in the stem of the pipe, to allow the smoke to pass, which latter enters by an
aperture and then passes around the tube and enters therein by a second
aperture in order to be inhaled through the mouth piece. This arrangement
prevents the nicotine from returning into the bowl of the pipe, or from getting
into the mouth piece.
The pipe can be easily cleaned for the mouth piece a and the reservoir c can be
readily removed from the stem of the pipe. This reservoir can also be separated
in its turn by unscrewing it from the insulating tube.
In the drawing I have represented a curved pipe, and a straight pipe which can
be made of any appropriate material and dimensions. The mounting can also be
made either to screw or slide on.
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
The arrangement of tobacco pipe capable of being taken to pieces, and provided
with a nicotine reservoir characterised by the combination of a reservoir c and an
insulating tube fitted with india rubber joint e, which by the arrangement of the
smoke passages and h, prevents the nicotine from returning into the bowl of
the pipe and from entering the mouth piece a. substantially as herein shown and
described.
ADOLPHE GROS.
