Improvements in Tobacco Pipes.
I, DAMASE MARC POULIN, of 336 Tremont Street, Boston Massachusetts
United States of America, Physician do hereby declare the nature of this inven-
tion 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 a smoking-pipe and has for its object to provide for the
condensation and separation of the volatile materials from the smoke in order to
prevent the injurious effects upon the system.
The invention is embodied in a pipe having a bowl provided with the usual stem
and containing an internal removable receptacle which fits closely in the bore of the
bowl, and is longitudinally movable therein.
The said internal receptacle is provided at its top with a cover of foraminous
material on which the tobacco is supported and through which the smoke passes
into the receptacle below, which is provided with a passage arranged to commu-
nicate with the stem of the pipe in the various positions that the inner receptacle
assumes while the pipe is being smoked.
The draft through the stem of the pipe thus exhausts the receptacle so that the
smoke passes down into it before passing out through the stem and the volatile
products of the smoke are condensed and collected in said receptacle.
The receptacle may be moved up in the bowl of the pipe as the tobacco is
consumed so that the combustion of the tobacco may always take place close to
the top of the pipe and the tobacco may be entirely consumed and all reduced
to ashes.
If desired the receptacle may be provided, with such chemicals as will render the
smoke the means for treating certain affections of the pharanx, and in all cases all
injurious effects of the smoke are prevented.
Fig. 1 is a longitudinal section of a pipe embodying this invention, the inner
receptacle being shown in full lines in the lowest position assumed in the use of the
pipe, the bowl of which may then contain its maximum charge of tobacco, while
the receptacle is shown in dotted lines in the position assumed when the tobacco is
nearly smoked or when a small charge is used.
Fig. 2 is a similar sectional view showing the parts in position for discharging
the contents of the collecting receptacle, without removing the same from the bowl
of the pipe.
Figs. 3 and 4 a side elevation and plan view respectively of the inner receptacle
removed from the bowl, and
Fig. 5 a sectional view showing a modified construction.
The bowl a may be of any suitable or usual shape and material being provided
with the usual stem b through which the smoke is withdrawn.
The said bowl a is open at its lower end and has a uniform bore a in which is
contained the movable inner collecting receptacle c which may be of any desired
material, glass being preferred on account of its cleanliness and owing to the fact
that its contents can be seen from the outside, although it is obvious that metal or
other material can be employed if desired.
The said receptacle is provided at its top with a cover d of foraminous material
such as gauze or netting on which the tobacco is supported and through which the
smoke passes down into said receptacle, which is provided near its upper part with
a passage which communicates with the stem 6 of the pipe which always enters
below the top d of the receptacle when the pipe is in use.

page_text: The said receptacle is longitudinally movable in the bore of the bowl as indi-
cated in full and dotted lines in Fig. 1, and may also be capable of rotation therein
as is shown by a comparison of Figs. 1 and 2.
When a large charge of tobacco is to be used in the bowl of the pipe the
receptacle c is moved well down in the bowl as shown in full lines Fig. 1, leaving
a large space above its top d in the bowl to receive the tobacco, and in order that
combustion may always be near the top of the bowl, and may be free and uniform
the receptacle c is moved up from time to time as the upper part of the tobacco
is consumed, thus raising the charge of tobacco until finally it is wholly
consumed.
The receptacle c must remain in communication with the passage through the
stem 6 during such movement, and in order to accomplish this result the passage c³
may be made of sufficient length to extend over the end of the stem passage in all
positions of the inner receptacle, or preferably the said passage is made in a
depression or groove c³ in the side of the receptacle which affords communication
from the stem to the passage c² and interior of the chamber c when the latter is
moved up as shown in dotted lines Fig. 1.
The outer surface of the receptacle c fits sufficiently closely in the bore of the
bowl to cover the groove c³ which in the construction shown in Figs. 1 to 4,
terminates a short distance above the bottom of the receptacle, so that when the
smoker draws through the stem b the air will be exhausted from the chamber c
causing the smoke to flow down through its perforated top into the said chamber
and finally to pass out from the chamber into the stem of the pipe, the said smoke
being cooled in the chamber and the volatile products condensed therefrom and
collected in the chamber.
The effects of pyridine, the most active empyreumatic product of the pipe smoke
on the system, as manifested by functional heart troubles, are wholly removed
by the passage of the smoke through the collecting chamber in the manner
described.
The liquids collected in the chamber c may be emptied from time to time if
desired, and the said chamber cleaned by removing it wholly from the bowl, and if
it is desired at any time to empty the chamber while smoking without disturbing
the tobacco that may then be in the pipe, this can be effected by turning the
chamber c around in the bowl to the position shown in Fig. 2, and then tipping
the bowl as shown so that the contents, of the chamber will flow out through the
passage and through the space in the groove c³ which is then uncovered by the
bowl as shown, the part of the bowl opposite the stem terminating above the part
at the same side with the stem.
If desired the sides of the bowl may be recessed or shaped as indicated by the
dotted line a³ Fig. 2 so as to afford a better opportunity for manipulating the inner
chamber e it being necessary only that the said bowl should have a downwardly
extending portion at below the stem so as to cover and close communication between
the groove and the outside of the pipe except through the stem and tobacco when
the receptacle is in its lowest position.
Instead of having the groove c³ terminate above the bottom of the receptacle c
and covered by a downward extension a' of the bowl, as shown in Fig. 1, it may be
made as shown in Fig. 5, the bowl being provided with an internal projection a",
just below the stem opening which projection fills the groove cand prevents direct
communication through the said groove outward at the lower end of the bowl.
With this construction rotation of the receptacle is prevented as long as the
same is in such position that the groove engages with the projection at, but the
receptacle may be emptied by moving it down far enough to bring the
below the said projection a10, as shown in dotted lines Fig. 5.
passage
c²
With this construction the groove may if desired extend the entire length of
the receptacle so that it can be moved longitudinally up entirely through the bore
of the bowl.

page_text: When the pipe is not in use the inner receptacle can be pushed up into the
bowl so as not to project below the opening at the bottom of the bowl, so that
the pipe will be as compact as an ordinary pipe not provided with the movable
collecting receptacle.
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. A pipe having a bowl open at top and bottom and a stem combined with a
receptacle longitudinally movable in said bowl said receptacle having a perforated
top, for supporting the tobacco in the bowl and a passage communicating with
the stem of the pipe in the various positions of said receptacle, substantially as
described.
2. The combination of a bowl open at top and bottom and having a longitudinal
bore, with a receptacle c longitudinally movable therein, said receptacle having a
perforated top and a groove or depression in its side, and the bowl having a
lateral passage leading from said groove in the said receptacle, substantially as
described.
