Certain Improvements in Tobacco-pipes.
I, THEODORE DUNKER, of 61 Edgbaston Street, Birmingham, Warwickshire,
Cigar Manufacturer and Merchant, do hereby declare the nature of this invention
to be as follows :-
This invention consists in the hereindescribed improvements in tobacco-pipes
which are carried out as follows:-
Between the pipe bowl and the mouth-piece I provide two chambers which are
by preference formed by a transverse partition in the mount which connects the
pipe stem and the mouth-piece together. The chamber which is nearer to the bowl
1 call the nicotine chamber because the nicotine from the bowl collects therein and
the other chamber I call the saliva chamber because the saliva runs therein from
the smoker's mouth. In the upper part of the said partition is a small hole with a
short projecting tube at each side which gives a free passage for the smoke from
the nicotine chamber to the saliva chamber but prevents any liquid passing from
one chamber to the other. To clean the nicotine chamber and the pipe stem the
latter has first to be removed from the mount. At the bottom of the saliva
chamber provide one or more holes which (when the pipe is in use) is or are

is fixed to the mouth-piece and can be turned thereby axially in one or the other
direction to either open the said hole or holes to allow the saliva to escape or to
close the said hole or holes. The movement of the said inner tube is limited by
a stop.
Or instead of the said inner tube being arranged to turn to open or close the
saliva outlet or outlets, the said tube may for these purposes be capable of being
moved endwise by pushing or pulling the mouthpiece.
Or the said inner tube may be arranged to act as a valve by being made much
smaller in diameter than the mount and arranged to cross the mount from the top
to the bottom. The said inner tube or valve is normally pressed upwardly by an
internal spring. When the said valve is pressed down the saliva can run out of
the saliva chamber through an opening or openings in the lower part of the valve
and mount, and when the valve resumes its normal position the said saliva hole or
holes is or are closed.
Or the said inner tube and the bottom opening or openings may be dispensed
with and the saliva chamber be emptied and cleaned by simply removing the mouth-
piece from the mount.

Certain Improvements in Tobacco-pipes.
1, THEODORE DUNKER, of 61, Edgbaston Street, Birmingham, Warwickshire,
Cigar Manufacturer and Merchant, 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 consists in the improvements in tobacco-pipes which I will describe
by referring to the accompanying drawing on which
Fig. 1 represents partly in section, a tobacco-pipe constructed according to this
invention;

page_text: Figs. 55
and 4 shew a further. modification;
Fig. 5 shews a further modification; and
Figs. 6 and 7 shew a further modification.
The same letters of reference indicate the same or corresponding parts in all
the figures.
Referring firstly more particularly to Fig. 1 between the pipe bowl and the
mouthpiece I provide two chambers marked respectively A and B which are by
preference formed by a transverse partition c in the mount C which connects the
pipe stem D and the mouthpiece E together. The chamber A. which is nearer to
the bowl I call the nicotine chamber because the nicotine from the bowl collects
therein and the other chamber B I call the saliva chamber because the saliva runs
therein from the smoker's mouth. In the upper part of the partition c is a small
hole with a short projecting tube ff at each side which gives a free passage
for the smoke from the nicotine chamber A to the saliva chamber B but prevents
any liquid passing from one chamber to the other. To clean the nicotine chamber A
and the pipe stem D the latter has first to be removed from the mount C.
bottom of the saliva chamber B I provide a hole g (or two or more holes may be
used) which (when the pipe is in use) is closed as shewn in Fig. 1 by the inner
tube H similarly perforated at 4 and fitting in the mount C. This tube H is fixed to
the mouthpiece E and can be turned thereby axially in one or the other direction
to either open the hole g (or holes when two or more are used) to allow the saliva
to escape from the chamber B or to close the hole or holes g when the pipe is being
smoked. The movement of the inner tube H is limited by the stop which
may be an indentation in the mouthpiece C engaging in the slot ² in the inner
Lube H.
At the

smoked the hole 3 matches the hole and the saliva hole is closed as shewn in
Fig. 6 and when the mouthpiece is turned so as to open the saliva hole as shewn
in Fig. 7 then the hole is closed by the blank end of the tube H, thereby
rendering it unnecessary to cover the bowl when the saliva is being blown out.
In the modification shewn by Fig. 2 instead of the inner tube H being arranged
to turn to open or close the saliva outlet or outlets g the tube H is for these
purposes made capable of being moved endwise in the mount C by pushing or
pulling the mouthpiece. In this case the hole is placed nearer to the stem D
than is the hole g and in a line therewith so that when the mouthpiece and tube H
are pulled outwardly the holes and g will coincide and allow of the saliva being
blown out, and when as shewn in Fig. 2 the mouthpiece E and tube H are pushed
inwardly as far as they will go the hole g is closed by the tube H.
In the modification of my invention shewn in Figs. 3 3 and 4 the inner tube H
is arranged to act as a valve by being made much smaller in diameter than the
mount C and arranged to cross the mount from the top to the bottom. The inner
tube or valve H is in this case arranged to be turned to open or close the outlet
from the saliva chamber as is the tube H in the tobacco pipes shewn by Fig. 1 and
Figs. 6 and 7. The valve H fits in the vertical cylindrical hole in the mount C
(see Fig. 3) and in the valve H are two transverse holes & corresponding with the
hole in the partition c. The saliva outlet hole is made in the valve H at about
right angles to the holes corresponding with the outlet hole g from the chamber B.
When the valve H is turned as shewn in Fig. 3 so that the holes & correspond with
the hole then the pipe is right for smoking and the outlet is closed but when
the valve H is turned so that the holes and y coincide (see Fig. 4) then the
hole is closed and the saliva can be blown out of the saliva chamber through the
holes and g. The ends of the mouthpiece E and pipe stem D which fit in
the mount. C are coned out as shewn and each fitted with a small tube to prevent
the nicotine and saliva running back. This is common in other tobacco pipes.
In the modification of my invention shewn by Fig. 5 the said inner tube H and

page_text: the bottom opening or openings y are dispensed with and the saliva chamber B is
emptied and cleaned by simply removing the mouthpiece E from the mount.
The small tube projecting beyond the partition c effectually prevents the
nicotine in the chamber A passing into the saliva chamber B no matter in what-
ever position the pipe may be placed.
One hole with its tube is all that is necessary but it will be evident that
without departing from the nature of my invention two or more of such holes and
tubes may be used in the partition.
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. In a tobacco pipe mount the use of a partition dividing the mount into two
chambers, that is a nicotine chamber and a saliva chamber, the said partition being
pierced by a small hole for the smoke furnished with a small tube projecting beyond
the partition to prevent the contents of one or either chamber passing into the
other, substantially as described.
2. In a tobacco pipe the use of a mount such as denoted by Claim I in combina-
tion with a mouthpiece and pipe stem which are coned at those ends which enter
the mount and are furnished with small projecting pipes in the coned ends to prevent
the contents of the nicotine chamber and saliva chamber running back into the
smoke hole in the pipe stem, substantially as described.
3. The combination with the pipe mount Chaving the partition and smoke
hole with its small projecting tube, of the tube H fitting in the mount and adapted
to turn with the mouthpiece and thus open or close an outlet g from the saliva
chamber substantially as hereinbefore described and shewn in Fig. 1 of the
accompanying drawing.
4. The combination with the pipe mount C having the partition and smoke
hole with its small projecting tube, of the tube H fitting in the mount and adapted
to turn with the mouthpiece and open or close the smoke hole and the outlet g
from the saliva chamber, substantially as hereinbefore described and shewn in
Figs. 6 and 7 of the accompanying drawing.
5. The combination with the pipe mount C having the partition e and smoke
hole with its small projecting tube, of the tube H fitting in the mount and adapted
to be moved to and fro by the mouthpiece and thus open or close an outlet g from
the saliva chamber substantially as hereinbefore described and shewn in Fig. 2 of
the accoinpanying drawing.
6. The combination with the pipe mount C having the partition and smoke
hole with its small projecting tube or tubes, of the tube or valve H crossing the
nount and adapted to be turned and thus open or close the outlet g from the saliva
chamber substantially as hereinbefore described and shewn in Figs. 3 3* and 4 of
he accompanying drawing.
7. The improved pipe mount C furnished with the partition c in which is the
moke hole and small pipe ƒ ƒ for the purposes and substantially as hereinbefore
escribed and shewn by Fig. 5 of the accompanying drawing.
Dated this 23rd day of March 1892.
