PROVISIONAL SPECIFICATION.
Improved Pipe for Smoking Tobacco.
I, WILLIAM HENRY PIERCE, of 3, Watling Street, Shudehill, Manchester, in the
County of Lancaster, Tobacco Pipe Manufacturer, do hereby declare the nature of this
invention to be as follows :-
The object of this invention is to provide a tobacco pipe which will be cool to
smoke and in which the nicotine or condensed product of combustion will be
prevented readily flowing to the mouth of the smoker.
It consists essentially in forming the pipe with a double chamber or passage
outside the central bore through which the smoke is caused to pass, by means of a
.thin tube or barrel closed at one end forming a partition between the passage in the
interior of the pipe stem and the projecting end of the mouthpiece which fits therein.
In carrying out the invention I construct the head or bowl of the pipe with a short
stem to receive a mouthpiece. The interior of the stem is bored out sufficiently large
to receive a small tube. This tube is made of any suitable material preferably of thin
metal electro-plated with silver, closed at that end nearest to the bowl of the pipe.
At its other end the tube fits over the projecting end of the mouthpiece and is provided
with a series of one or more holes through which the smoke passes. The projecting.
end of the mouthpiece passes into the interior of the tube nearly to the closed end and
at or near its extremity is provided with one or more holes for the passage of the
smoke into the bore of the mouthpiece. By this arrangement the smoke has first to
traverse the chamber or passage formed between the stem and the inserted tube then
back through the chamber formed of the interior of the tube and the projecting end
of the mouthpiece and finally through the mouthpiece to the mouth of the smoker.
The oily products from the tobacco will largely condense in the two chambers formed
by the inserted tube and will be prevented mixing with any saliva which may flow
from the mouth of the smoker which will be retained in the mouthpiece from which it
can easily be shaken out. An additional advantage will be that ash from the tobacco
will not be able to enter the bore of the mouthpiece and the saliva will be prevented
running to the bowl of the pipe which will allow of the pipe being smoked dry to the
bottom.

COMPLETE SPECIFICATION.
Improved Pipe for Smoking Tobacco.
I, WILLIAM HENRY PIERCE, of 3, Watling Street, Shudehill, Manchester in the
County of Lancaster, Tobacco Pipe Manufacturer, 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 object of this invention is to provide a tobacco pipe which will be cool to smoke
and in which the nicotine or condensed products of combustion or other moisture in
the stem will be prevented readily flowing to the mouth of the smoker:
It consists essentially in forming the pipe with two concentric chambers or passages
outside the central bore, through which the smoke is caused to pass by means of a
thin tube or barrel closed at one end forming a partition between the passage in the
interior of the pipe stem and the projecting end of the mouthpiece which fits therein,
whereby the smoke is caused to travel three times the length of the stem, before
reaching the mouthpiece.

page_text: Referring to the accompanying drawing.
Fig. 1, is a sectional elevation of tobacco pipe, constructed according to my
invention.
Fig 2, transverse section on line -y.
Fig. 3, plan of mouthpiece with tube attached, removed from the stem of the pipe.
The head or bowl of the pipe is constructed in the usual way, with a short stem to
receive a mouthpiece. The interior of the stem A. is bored out sufficiently wide to
receive a small tube B, which fits over the projecting end of the mouthpiece. The
mouthpiece C, of the pipe may be made of any ordinary material and is fitted with a
projecting piece D, nearly equal in length to the stem A. The tube B, fits over the
projecting end D, of the mouthpiece, leaving an annular space or passage between
the two, at one end it fits tightly onto a shoulder on the mouthpiece and at the other
end or that nearest to the bowl of the pipe it is closed to prevent the passage of
smoke. At or near the end connected to the mouthpiece and preferably on the top
side it is provided with a number of holes or perforations b, through which the smoke
passes into the chamber or passage b, surrounding the projecting end D. The tube is
male of any suitable material preferably of thin metal electro-plated with silver. The
projecting end D, of the mouthpiece extends into the interior of the tube B, nearly
to the closed end and at or near its extremity is provided with one or more holes for
the passage of the smoke into the bore of the mouthpiece c. By this arrangement
the smoke has to traverse backwards and forwards three times the length of the stem
before reaching the mouth, having first to traverse the chainber or passage a formed.
between the stem A, and the inserted tube B, then back through the chamber or
passage b, formed of the interior of the tube B, and the projecting end D, of the
mouthpiece and finally through the bore c of the projecting piece D, to the mouth of
the smoker. The oily products from the tobacco will largely condense in the two
passages formed by the inserted tube and will be prevented mixing with any saliva
which may flow from the mouth of the smoker, which will be retained in the mouth-
piece from which it can easily be shaken out.
The smoke as it passes backwards and forwards along the passages is thoroughly
cooled before reaching the mouth. An additional advantage will be that ash from the
tobacco will not be able to enter the bore of the mouthpiece and the saliva will be
prevented running to the bowl of the pipe which will allow of the pipe being smoked
dry to the bottom.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :
"
1. A pipe for smoking tobacco having a tube closed at one end inserted in the stem,
and covering a projecting end piece attached to the mouthpiece, thereby forming a
passage three times the length of the stem for the smoke to traverse, substantially as
described.
d
2. In a tobacco pipe the combination with the stem A, of the tube B, closed at one
end, and the projecting piece D, forming the concentric passages or chambers a, a
and c, substantially as described and shown.
