PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes.
I, THOMAS CONVERY, of 10 The Avenue, Wallsend on Tyne, Northumberland,
Engineman, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved tobacco pipe, and has for its object to
provide a pipe which will prevent nicotine or tobacco juice reaching the mouth of
the smoker.
In carrying out my invention I form the stem of the pipe with a recess or cavity
into which the passage from the bowl opens. A number of small balls of pipe clay,
about an eighth of an inch in diameter, are placed in this recess, filling it, and the
mouthpiece is then fitted in place, holding the balls securely.
The balls are made as porous as possible and only hard enough to keep their
form.
The smoke will pass freely through this recess between the balls, but will deposit
any nicotine or moisture on its way. A small groove is formed on the end of the
mouthpiece, situated in the recess, extending across it, but not as far as the edge,
and deepening towards the central hole. This groove is for the purpose of allowing
the smoke to enter the passage more freely. A similar groove is formed at the
other end of the recess in the stem.
Dated this 6th day of January 1893.

COMPLETE SPECIFICATION.
.Improvements in Tobacco Pipes.
I, THOMAS CONVERY, of 10, The Avenue Wallsend on Tyne, Northumberland,
Engineman, do hereby declare the nature of my said 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 relates to an improved tobacco pipe, and has for its object to
provide a pipe which will prevent nicotine or tobacco juice reaching the mouth of
the smoker.
In carrying out my invention, I form the stem of the pipe with a recess or cavity
into which the passage from the bowl opens. A number of small balls of pipe clay,
or the like, about an eighth of an inch in diameter, are placed in this recess, filling it,
and the mouthpiece is then fitted in place, holding the balls securely. The balls
are made as porous as possible and only hard enough to keep their form.
The smoke will pass freely through this recess between the balls, but will deposit
any nicotine or moisture on its way. A small groove is formed on the end of the
mouthpiece, situated in the recess extending across it, but not as far as the edge,
and deepening towards the central hole. This groove is for the purpose of allowing
the smoke to enter the passage more freely. A similar groove is formed at the
other end of the recess in the stem.
The balls can be readily removed and replaced when they are saturated, there
being no delicate parts to fit together.
In order that the invention may be more clearly understood, reference is had to
the accompanying drawings, in which
Fig. 1 is a section of the complete pipe, Fig. 2 an end view and Fig. 3 a section
of the inner end of the mouthpiece.

page_text: The bowl A of the pipe is furnished with the ordinary small passage a at its lower
end, leading into the chamber B in the stem C, which is made with thin walls to
enable a chamber of sufficient size to be obtained.
A number of small balls D of the kind above described is placed in the inner
chamber B, filling it sufficiently to prevent them rattling or shaking when the pipe
is moved. The mouthpiece E is fitted in the stem C in any suitable manner by
screwing or otherwise, and serves to retain the balls in place. At the end of the
.mouthpiece where the passage opens into the chamber, a small groove e is formed,
extending diametrically across it, shown clearly in Figs. 2 & 3, deepening towards
the centre. A similar groove c is formed in the stem at the other end of the
chamber; both for the purpose of leading the smoke more freely through the
passages. The same arrangement can be employed for cigar and cigarette holders,
the bowl being dispensed with, and the stem extended slightly.
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) A tobacco pipe with a stem, having a closed chamber in which a number of
small balls of absorbent material is placed, the passage for the smoke leading through
the chamber, substantially as and for the purpose specified.
(2) A tobacco pipe having a stem formed with a chamber or receptacle in which
a number of balls of absorbent material is placed, and a mouthpiece closing the
chamber and retaining the balls, substantially as described and for the purpose
specified.
(3) A tobacco pipe consisting of a bowl A, a stem C with chamber B and
groove e at the end of passage a and a mouthpiece E with groove e, closing the
chamber B and retaining the balls D with which it is supplied, substantially as
described and shown.
Dated this 18th day of February 1893.
