Improvements in Tobacco Pipes.
I, WILLIAM THOMSON NEILL, of Portobello, Dunedin, in the Colony of
New Zealand, Surveyor, do hereby declare the nature of this invention to be as
follows:-
My invention relates to tobacco pipes and has for its objects constructing the
same in a simple and cheap manner; and so as to prevent the passage of nicotine
from the bowl of the pipe to the mouth of the smoker; to reduce the temperature
of, and extract the moisture from, the smoke as it passes through the pipe; and
so to connect the parts of the pipe together that they may be readily taken apart
to be cleaned.
I attain these objects of my invention by means of a pipe having a bowl, which
may be of wood or any other suitable material, and a screwed stem, and at its lower
part a small passage for the smoke.
An elongated conical chamber is chased upon the interior of its larger end with
a screw thread to receive the screwed stem of the bowl.
I prefer to make this couical chamber of similar material to the bowl, and
circular in cross section.
A disc having a perforation at its upper part is held between the screwed stem
and a shoulder, provided for that purpose, within the conical chamber. A small
receptacle is thus formed for the free moisture from the tobacco. From this
receptacle the smoke passes through the perforation in the upper part of the disc
into the conical chamber, the interior surface of which is made as large as possible
consistent with appearance, to provide surface for condensation of moisture still
left in the smoke after passing through the small receptacle; and the sides of
this same chamber are made as thin as possible consistent with strength to
permit of free radiation of heat from the smoke and thus reduce the temperature
of the latter.
The mouthpiece is placed in the narrow end of the conical chamber, into which
it projects for a considerable distance, and being held with its axis coincident with
that of the chamber, its inner end is isolated from the surrounding parts, with the
result that whilst the smoke may pass freely, moisture is prevented from gaining
access to the mouth of the smoker.
To clean the pipe the bowl is unscrewed from the conical chamber, and the disc
and mouthpiece taken out, when the parts may be readily examined and cleaned
by washing or other means.
By reducing the diameter of the bowl, the same may be made suitable for
holding and smoking cigarettes with advantages equal to those when tobacco is
being smoked in the bowl.

I, WILLIAM THOMSON NEILL, of Portobello, Dunedin, in the Colony of
New Zealand, Surveyor, 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 :—
My invention relates to tobacco pipes and has for its objects constructing the
same in a simple and cheap manner, and so as to prevent the passage of nicotine
from the bowl of the pipe to the mouth of the smoker; to reduce the temperature
of, and abstract the moisture from the smoke as it passes through the pipe; and so
to connect the parts of the pipe together that they may be readily taken apart to
be cleaned.
I attain these objects of my invention by a pipe constructed as illustrated on the
accompanying drawing whereon similar letters refer to similar parts throughout the
views.
Fig. 1, is a longitudinal section of the pipe.
Fig. 2, is a cross section on line A. B. (Fig. 1).
(a) is the bowl which may be made of wood or other suitable material and has
a screwed stem (a¹) and at its lower part has a small passage (a2) for smoke.
(b) is an elongated conical chamber which I prefer to be circular in cross section
and which may be made of similar material to the bowl, and upon the interior of
its larger end is chased a screw thread to receive the screwed stem (a), or these
two parts may be connected together by any other suitable means. (¹) is an annular
shoulder formed within the said chamber (b) against which the disc (2) may rest
and be held. in position when the stem (a¹) is screwed home. The stem (a) and
disc (2) thus together form the chamber (a³) and have an inlet (a2), as before
mentioned, and an outlet (a) for the smoke. At its smaller end the said chamber (b)
is provided preferably with a tapered hole to receive the mouthpiece (c), which may
be made of amber or any other suitable material. This said mouthpiece has its
inuer end (c) projecting for a considerable distance into the chamber (6); the axis
of the one being coincident with that of the other.
The effect of smoking tobacco in a pipe such as described is that, the smoke
passes from the bowl (a) through the passage (a) to the chamber (a) where
nicotine and other free moisture from the tobacco is detained. The smoke then
passes through the small opening (a) into the chamber (6). The interior surface
of this chamber is made as large as possible consistent with appearance, to provide
surface for condensation of moisture still retained in the smoke after passing
through chamber (a³); and the sides of this same chamber are made as thin as
possible consistent with strength, to permit of free radiation of heat from the
smoke and thus reduce the temperature of the latter.
By isolating the narrow end (c) of the mouthpiece (c).from the surrounding
parts as shewn on the drawing, the smoke after being further cooled and desiccated
in the chamber (b) as just described, may be drawn through the mouthpiece (c) and.
its moisture left behind in the chamber (b).
The disc (2) may be dispensed with, though I prefer to employ the same, as
better results are then obtained.
To clean the pipe, the bowl (a) is unscrewed from the chamber (b), and the
disc (6) and mouthpiece (c) taken out, when the parts may be readily examined
and cleaned by washing or other means.
It will be obvious by reference to the drawing that by reducing the diameter of
the bowl, the same may be made suitable for receiving and smoking cigarettes with
advantages equal to those when tobacco is being smoked in the bowl.

page_text: I am aware that pipes have been made with improvements intended to overcome
the objectionable passage of moisture from tobacco to the mouth of the smoker
and I do not claim such pipes broadly.
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. The herein before described improvements in tobacco pipes consisting of the
combination of bowl (a) having stem (a) to form with the perforated disc (62) a
chamber (a), with a large chamber (b) into which the mouthpiece (c) extends and
has its inner end (c) isolated, whereby the smoke may freely pass, its temperature
be reduced, and its moisture retained within the pipe, substantially as and for the
purposes as set forth and as illustrated.
2. The hereinbefore described improvements in tobacco pipes consisting of the
combination of bowl (a) having stem (a'), with a large chamber (6) into which the
mouthpiece (c) extends and has its inner end (c¹) isolated, whereby the smoke may
pass freely, its temperature be reduced, and its moisture retained within the pipe,
substantially as set forth.
