PROVISIONAL SPECIFICATION.
An Improvement in Tobacco Pipes.
We CLAUDE MARIE RAYMOND JEANTET, and CLAUDE MARIE HENRY
JEANTET, both of Saint Claude (Jura) France, Pipe Manufacturers do hereby
declare the nature of this invention to be as follows:-
:-
This invention has for its object to provide tobacco pipes of all kinds with one or
more purifiers whereby to neutralize the nicotine or deprive it of its injurious
qualities.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 shews a longitudinal section of a pipe provided with two purifiers.
Figure 2 shews longitudinal and end views of one of the purifiers.
Figure 3 shews the intermediate union piece.
Figure 4 shews the purifier chamber in the mouth piece.
Figure 5 shews a longitudinal section of a pipe provided with only one
purifier.
The pipe stem a is formed with a chamber b to receive a plug or cylinder c of
porous pipe clay having a number of small longitudinal bores d for the passage of
the smoke. e is a union or joint piece fitting friction-tight into the stem a and
screwed into the mouth piece g which is also formed with a chamber to receive a
second perforated plug c similar to the first. The ends of the union piece press
against the two plugs and are pierced obliquely with a number of small holes h for
the passage of the smoke through the outermost perforations of the plugs c.
These porous purifier cylinders e are impregnated with tannin, which possesses
the property of neutralizing the nicotine and forming with it a salt insoluble except
in alcohol. Salt of sorrel (oxalic acid) and quinine have also the same property
and may be employed for the same purpose; coffee, tea, and cinchona, may also
be employed as purifying agents in the second cylinder contained in the mouth-
piece.
Only one purifying cylinder may be employed, as shewn in Figure 5.

COMPLETE SPECIFICATION.
An Improvement in Tobacco Pipes.
We, CLAUDE MARIE RAYMOND JEANTET and CLAUDE MARIE HENRY
JEANTET, both of Saint Claude (Jura) France, Pipe Manufacturers, 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 to neutralize the injurious effects of the nicotine
resulting from the smoking of tobacco in pipes, by providing tobacco pipes of all
kinds with one or more purifiers impregnated with agents capable of reacting on the
nicotine, conveyed by the smoke or otherwise, by forming therewith a salt insoluble
in the saliva, thereby depriving it of its pernicious qualities.

page_text: Reference is to be had to the drawings accompanying the Provisional
Specification, in which
Figure 1 shews a longitudinal section of a pipe provided with two purifiers.
Figure 2 shews longitudinal and end views of one of the purifiers.
Figure 3 shews the intermediate union piece.
Figure 4 shews the purifier chamber in the mouth piece.
Figure 5 shews a longitudinal section of a pipe provided with a single
purifier.
The pipe stem a is formed with a chamber b to receive a plug or cylinder c of
porous pipe clay, preferably that known as givet clay, having a number of small
longitudinal bores d for the passage of the smoke. e is a union or joint piece fitting
friction tight into the stem a and screwed into the mouth piece g which is also
formed with a chamber to receive a second perforated plug c similar to the first.
The ends of the union piece press against the two plugs and are pierced obliquely
with a number of small holes h for the passage of the smoke through the outermost
perforations of the plugs c. These porous purifier cylinders c are impregnated with
tannic acid or crystallised tannin which possesses the property of neutralizing the
nicotine and forming with it a salt insoluble except in alcohol. For this purpose
the tannic acid is dissolved in hot water until saturated to form a bath in which the
purifying cylinders are immersed for about twelve hours. Salt of sorrel (oxalic
acid) and quinine have also the same property and may be employed for the same
purpose; coffee, tea, and cinchona, may also be employed as purifying agents in the
cylinder contained in the mouthpiece.
Only one purifying cylinder may be employed, as shewn in Figure 5.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is―
The combination, with a tobacco-pipe, of one or more purifiers (through which
the smoke must pass) impregnated with matters capable of reacting on the nicotine
by forming therewith a salt insoluble in the saliva, substantially as herein described
and illustrated in the drawings.
