PROVISIONAL SPECIFICATION.
Improvements in Pipes for Smoking Tobacco.
I, GEORGE BARTON, of Preston Street, Hulme, Manchester, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
The invention is designed with the object of constructing a tobacco pipe in which
the nicotine will be prevented entering the mouth of the smoker and saliva
therefrom be prevented entering the bowl of the pipe and in which a perfect
combustion of the tobacco in the bowl will take place so as to keep dry and burn
down to the bottom.
It consists essentially in constructing the pipe with a double bowl or head with a
chamber or passage between the two extending nearly up to the top and a cross
stem extending from the top of this chamber to the mouth piece so that the smoke
must pass from the bottom of the bowl up through the chamber or passage to the
top and then down through the cross stem to the mouth piece.
In carrying out the invention I construct the pipe of briar or other suitable
material with a second or internal bowl of clay, wood or other material. The
inner bowl fits preferably loosely into the other leaving a space or chamber
between, and the two are connected together at the mouth. The inner, bowl may
be removable or made a fixture. In the bottom of the inner bowl, a number of
draught holes are placed through which the smoke passes from the tobacco..
A cross or auxiliary stem or passage connects the top of the chamber or passage
with the mouth piece or stem of the pipe to convey the smoke from the top of this
chamber. The cross stem may either be made a fixture or preferably removable
so that it can be easily cleaned. At the foot of the cross stem if desired
there may be formed a chamber in the stem in which any liquid or oily matter
will collect.
"
Plugs or covers may be placed at the bottom of the outer bowl and also at the
bottom of the cross stem to allow for cleaning.

COMPLETE SPECIFICATION.
Improvements in Pipes for Smoking Tobacco.
1, GEORGE BARTON, of Preston Street, Hulme, Manchester, in the County
of Lancaster, Engineer, 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 :-
The invention is designed with the object of constructing a tobacco pipe in which
the nicotine will be prevented entering the mouth of the smoker and saliva
therefrom be prevented entering the bowl of the pipe and in which a perfect
combustion of the tobacco in the bowl will take place so as to keep dry and burn
down to the bottom.
It consists essentially in constructing the pipe with a double bowl or head with a
chamber or passage between the two extending nearly up to the top and a cross
stem extending from the top of this chamber to the stem or mouth piece so
that the smoke must pass from the bottom of the bowl up through the chamber

mouth piece.
It will be fully described with reference to the annexed drawings.
Fig. 1, side elevation and
Fig. 2, sectional elevation of a pipe constructed according to my invention.
The pipe is constructed of briar or other suitable material with a second or
internal bowl B of clay or other suitable material. The inner bowl B preferably
fits loosely or removably into the head with a chamber between the two.
I prefer
to have the inner bowl made with a flange or rim provided with a screw thread by
which it can be connected to the head. It may however be connected in any
other way such as by a metal ring and instead of the chamber a passage down one
side may lead to the bottom of the bowl.
In the bottom of the inner bowl are formed one or more draught holes which
communicate with the passage or chamber and through which the smoke from the
tobacco is drawn into this chamber or passage.
The stem A of the pipe which externally is of ordinary appearance is made solid
or without a bore at its junction with the head and connection is made between the
chamber or passage and the stem or mouthpiece by an auxiliary or cross stem C
which at one end enters or communicates with the top of the chamber and at the
other with the stem or mouth piece.
The cross stem C is preferably made of a metallic tube inserted as shown and may
either be a fixture or removable.
At the foot of the cross stem C is provided an inclined chamber D into which
both it and the bore of the stem or mouthpiece open. Any liquid or oily matter
condensing in or running from the cross stem C or mouthpiece F will collect in the
chamber and can be withdrawn by removing the cap E.
When required the cross stem C can be easily cleaned after removing the cap E
and the inner bowl B by passing a wire or brush through it.
Having now particularly described and ascertained the nature of the said inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A tobacco pipe constructed with an auxiliary or cross stem (such as C) one
end of which opens into or communicates with a chamber or passage leading from
the bottom to the top of the bowl and the other with the bore of the stem or
mouthpiece substantially as described.
2. A tobacco pipe constructed with a removable inner bowl with a chamber
surrounding it, a cross stem (such as C) connecting the top of this chamber with
the bore of the stem or mouthpiece and a chamber in the stem to collect liquid or
oily matter substantially as described.
3. A tobacco pipe having the several parts constructed and arranged substantially
as described and shown.
