PROVISIONAL SPECIFICATION
Improvements in the Construction of Tobacco Pipes.
We, FRANCIS JOHNSON, of 97, Armley Road, Leeds, in the County of York,
Draughtsman, & WILLIAM WILKINSON, of Rock Cottage, Armley, Leeds, in
the County of York, Engineers' Manager, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in tobacco pipes, & has for its object, the
construction of a pipe the principle of which is to prevent any liquid or nicotine,
which is formed in the bowl, from entering into the pipe stem or mouth piece.
In order to effect the above object we construct a pipe of any suitable material
having two chambers or bowls, the one fitted into the other and forming at the top
an air tight joint, below which a clear space is left between the two, so as to forin
an outer bowl or smoke chamber.
The inner bowl is used as a receptacle for the tobacco, and by means of one or
more holes formed in the bottom is made to communicate with the outer bowl or
smoke chamber.
The smoke on being drawn in the usual way passes from the tobacco bowl into
the smoke chamber, from which it is drawn upwards by means of a hole formed in
the top part of the outer shell, the said hole passing downwards through the
thickness of the shell until it reaches a small recess formed in the bottom of the
pipe, the same recess having direct communication with the pipe stem. By this
arrangement, the tobacco bowl has no direct communication with the pipe stem,
and any liquid coming therefrom would fall to the bottom of the smoke chamber, at
the same time the smoke would flow upwards to the top of the smoke chamber &
then take a downward course through the outer shell or bowl to the recess which
communicates with the pipe stem or mouth piece, being purified & cooled by the
continual supply of air which is always passing into the smoke chamber.
In order that the liquid or nicotine may be expelled from the smoke chamber a
removable plug or cock is inserted into the bottom, on the removal of which the
liquid can be expelled by simply blowing through the pipe stem.
This plug also forms the bottom of the recess where the two holes forming the
smoke passages meet & when removed admits of a wire being inserted in any of
the holes at one end & drawn out at the other, thereby allowing easy access to the
smoke passages for the purpose of cleaning.
Dated this 5th day of May 1890.

page_text: In order to more fully describe our invention reference is made to the accompany-
ing drawing.
Fig. 1 is an outside view.
Fig. 2. is a longitudinal section.
In order to effect the above object we construet a pipe of any suitable material,
having two chambers or bowls A. B. the one fitted into the other and forming at
the top an air tight joint below which a clear space D is left between the two so na
to form an outer bowl or smoke chamber.
The inner bowl B is used as a receptacle for the tobacco and by one or more
holes H. formed in the bottom, is made to communicate with the outer bowl or
smoke chamber D.
n
The smoke on being drawn in the usual way passes from the tobacco bowl B
into the smoke chamber D. from which it is drawn upwards by means of a hole (
formed in the outer shell A. the said hole passing downwards through the thickness
of the shell until it reaches a small recess. formed in the bottom of the pipe, the
said recess having direct communication with the pipe stem N. by this arrangement
the tobacco bowl B. ha no direct communication with the pipe stem and any
liquid coming therefrom would fall to the bottom of the smoke chamber D at the
same time the smoke would flow upwards to the top of the smoke-chamber and then
takes a downward course through the outer shell or bowl A. to the recess which
communicates with the pipe stem or mouthpiece being purified & conted by the
continual supply of air which is always passing into the smoke clamber, in order
that the liquid or nicotine may be expelled from the smoke chamber a removable
plug or cock O is inserted into the bottom, on the removal of which the liquid can
be expelled by simply blowing through the pipe stem.
This plug also forms the bottom of the recess where the two holes G. P. forming
the smoke passages meet; and when removed admits of a wire being inserted in any
of the hole at one end & drawn out at the other thereby allowing easy access to
the smoke passages for the purpose of cleaning.
Having now particularly described & ascertained the nature of our said inven-
tion, & in what manner the same is to be performed, we declare that what we
claim is
(First). The construction of a tobacco pipe in the outer bowl or shell of which a
hole G is formed for communication between the smoke chamber and the pipe stem
substantially as herein described & illustrated by the accompanying drawing.
(Second). The construction of a tobacco pipe with a hole or recess which
communicates with the smoke chamber & the smoke passages for purposes of
cleaning, substantially as heroin described & illustrated by the accompanying
drawing.
(Third). The plug ( for closing the communication between the smoke passage,
& the bottom of the smoke chamber substantially as herein described & illustrated
by the drawing.
(Fourth). The general construction of a tobacco pipe having two bowls or
chambers A. B & forming between the two a space or smoke chamber D. substan-
tially as herein described & illustrated by the accompanying drawing.
