the Mouth.
1, EDOUARD FRANÇOIS BOUR, of 104 Camden Street N.W. London, a medical
student, do hereby declare the nature of this invention to be as follows:-
Pipes, cigar & cigarette holders, provided with chamber for collecting the products
of the condensation of tobacco smoke, have always had the disadvantage of leaving a
certain length of tube (the mouthpiece) where condensation will still continue. The
products of this further condensation, diluted with the saliva entering the tube, is,
when sucked into the mouth, the cause of great annoyance to smokers.
My invention is to obviate to this inconvenience.
To reach this end, my pipe is thus constructed :-
I start first by mentioning the chief feature of the invention, namely, a collecting
chamber situated in the mouthpiece itself as near as possible, or suitable, to its
mouth end.
This chamber, which for description sake I will style Chamber No. 2, having any
suitable shape, is to be bored or drilled into any suitable material for mouthpieces, or
be made in metal & screwed into or coupled to any suitable mouthpiece, or else, if
more convenient, to be made thus:
The bore in the mouthpiece, of suitable caliber, within one inch of its mouth end is
made to suddenly enlarge, funnel-shape like, to a convenient diameter & then, resume
again the cylindrical shape & be continued thus to the very mouth end. There, the
mouth-piece is to be cut in a plane perpendicular to its bore & have no rim; (the rim
which prevents pipes from slipping from between the teeth) into this enlarged bore is
to be either pushed in or screwed in, as far as suitable, a hollow cylinder in metal one
aperture of which (the one nearest the mouth) is to be closed except at the centre,
where is to be a hole into which a suitable length of metal tube, by far smaller in
diameter than the cylinder, is to be inserted & soldered thus, that one portion of it
would project back & end into the interior of the cylinder.

page_text: The remaining portion which is outside the cylinder is to be screw shaped on it
a knob constituting the rim of the mouthpiece is to be screwed-This knob is to be of
the same material than the mouthpiece & made flush with it so that in outward
appearance the pipe might be alike the ordinary ones.
At the opposite end of this mouthpiece (the end nearest the furnace) in its bore, is
driven a little funnel shaped tube in metal or other suitable material; or else, this
funnel & the mouthpiece might be made into one single piece without solution of
continuity.
The improvement there lies in the funnel shaped ending of the bore-The action of
which will be further on explained.
The rim of this funnel which looks towards the body of the pipe is to be a little
smaller in diameter than the portion of the mouthpiece which is to be driven into the
stem of the pipe.
This stem is to be bored in such a way that when the mouthpiece should have been
coupled with it, there would remain a chamber around the funnel shaped tube. This
chamber will style Chamber No. 1.
My pipe works thus: Chamber No. 1 receives the moisture which collects in front
of it & similarly to other pipes having chambers interposed between the furnace & the
mouthpiece. But the part to which 1 draw particular attention, is the working of
the mouthpiece. The moisture or fluid in it always tend to gravitate towards
Chamber No. 1, and, reaching the funnel shaped tube which opens into its centre, will
spread over its rim; thereby losing its tendency to collect into a drop-a fact which
occurs when the caliber of the bore is uniform & too small-that would fill the bore in
mouthpiece & then be sucked up. Were the moisture to form into a drop, before
reaching the funnel shaped portion of the hore, & be sucked up the mouthpiece, it
would be prevented from entering the mouth, for, spreading over the wall of
Chamber No. 2 it would collect in the lowest portion of it, would block no more the
bore whilst the smoker is drawing-& would, between the inhalations, gravitate into
& fall into Chamber No. 1.
The smoker aware of moisture in his mouthpiece by the clicks ellicited each time he
inhales the sunoke, by blowing through his pipe would drive it into Chamber No. 1-
These improvements can be adapted to pipes, cigar & cigarette holders of whatever
shape or material.

the Products of Condensation of Tobacco Smoke from Entering
the Mouth.
I EDOUARD FRANÇOIS BOUR, of 104 Camden Street, London N.W. Surgeon,
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:-
Hitherto in pipes, cigar and cigarette-holders, in which a chamber or reservoir is
provided for the collection of the products of condensation of tobacco smoke, a dis-
advantage still exists in the long tube forming the mouthpiece in which condensation
of the smoke continues. The products of this further condensation added to the
saliva entering the mouthpiece, when sucked into the mouth during the act of
smoking, is a cause of much annoyance to smokers. My invention has for its object
therefore to provide a means of overcoming the above mentioned disadvantage, and
by maintaining the true aroma of the tobacco, to spare the smoker the unpleasantness
occasioned by the introduction into the mouth of the oily products of condensation.
In carrying out my invention I provide a Pipe A, the stem a of which is bored
longitudinally to form a chamber B. In the end of the stem a is inserted a mouth-
piece C also bored longitudinally to form a chamber D. Said chamber D is tapered
at the end nearest the stem a to meet a small channel, within which latter is
inserted a funnel shaped tube c. of metal-or other suitable material for the purpose
hereinafter to be more particularly described; or said tube c may form part of the
mouth-piece. In the end of the chamber D of the mouth-piece C is fitted by means
of a bayonet joint fastening, by screwing, or otherwise, a flanged plug E, having a
channel of suitable diameter formed therein, in which is inserted a short tube g of
metal or other suitable material or substance.
From the foregoing it will be observed that I employ two distinct chambers B
and D, separated by the contracted channel b, both of which perform the same
function of collecting therein the products of condensation, thus :-Upon drawing the
smoke into the mouth from the bowl A of the pipe, said smoke circulates in its
passage in the chamber B, upon the inner surface of which the producis of condensa-
tion accumulate, and ultimately fall to the lower part thereof, all access of the fluid to
the chamber 1, being prevented by the obstruction formed by the funnel shaped
tube c above referred to. The smoke having parted with a portion of the products of
condensation, passes by way of the channel into the chamber D of the mouthpiece
where it undergoes a further process of condensation, the products thereof collecting
upon the surface of the chamber D, ultimately falling to the lower part, which may
then, by holding the pipe vertically, be emptied into the chamber B, or both chambers
may be emptied by withdrawing the mouthpiece C from the stem a of the pipe A.

page_text: The combined products of condensation and saliva are prevented from entering the
mouth, by reason of the projecting tube g, which checks all but the now highly
purified smoke from entering the mouth.
As a modification of the above described method of forming the mouthpiece, I may
bore the latter, from the end which joins the stem a of the pipe A, a recess being
formed round the contracted channel f, to serve as an obstruction to the passage of
the fluid products of condensation. According to this modification, a plug of the
sanie material of which the mouthpiece is made, (or if desired any other suitable
material or substance may be employed) having a double funnel shaped channel
formed therein, would be inserted in the open end of said mouthpiece C.
From the foregoing it will be seen that in a pipe formed in accordance with my
invention, the contracted channel is too short to allow, after condensation of the
smoke in the chambers B and D, of the formation therein of a bead or globule of
moisture and nicotine; thus, these products of condensation being intercepted
immediately before the entry of the smoke into the mouth, the full purity of the
aroma of the tobacco is maintained undeteriorated by admixture with said products
of condensation.
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
1st. In pipes, cigar and cigarette holders the employment of a mouthpiece having
a cylindrical chamber formed therein, one end of which is tapered substantially as and
for the purposes herein described.
2nd. In a chambered mouthpiece for pipes, cigar and cigarette holders the adapta-
tion thereto of two small tubes or tubular projections or extensions substantially as
and for the purposes herein set forth and shown.
3rd. The improved pipe, cigar, and cigarette holders for preventing the products
of condensation of tobacco smoke from entering the mouth substantially as herein set
forth.
