PROVISIONAL SPECIFICATION.
Improvements in Pipes for Smoking, Tobacco.
I, THOMAS PARRY of Hillcroft Silverdale Sydenham Gentleman, do hereby
declare the nature of this invention to be as follows:-
The object of my invention is to form a pipe which shall prevent nicotine being
drawn into the mouth. while being smoked. My invention chiefly relates to that
part of the pipe known as the stem and which extends between the bowl and the
mouthpiece.
The bowl of my improved pipe is formed and fashioned in the same way as.an
ordinary pipe and luminates at the bottom in the usual small aperture leading out
to the stem.
On reaching the stem this small aperture or passage immediately widens out,
and the remainder of the stem consists of a hollow tube-at the end of which is placed
the mouthpiece of the pipe.
This mouthpiece is attached to the stem by a screw joint or any other approved
means.
The mouthpiece is formed for a short distance near the joint in the manner of a
tube like the stem, and then the hollow is gathered together by the sloping sides
and a small passage is formed in the remainder of the mouthpiece similar to that
found in ordinary mouthpieces.
I now arrive at the principal part of my invention which consists of a long piece
of clay or asbestos formed on its outer surface or surfaces so as to just comfortably
fit into the tube which forms the stem of the pipe and of sufficient length so that
when placed as far as possible in this stem it shall project out a short distance, such
projecting portion being covered by the mouthpiece when screwed on.
This long piece of clay or asbestos is pierced longitudinally by a series of small
straight holes which are circular in diameter, and through these holes passes the
smoke from the bowl of the pipe to the mouth of the smoker.
The object of sthis clay, ori asbestos. piece aforementioned is to intercept the
nicotine.
When the pipe becomes foul from continued use the mouthpiece is unscrewed
and the clay piece" easily withdrawn (as it is found to project slightly from the
stem) and it can then be purified and made clean by burning in a sufficient heat
and afterwards replaced within the stem, and the mouthpiece added when my
improved pipe will again be found to be sweet and clean.
Although I have herein referred to the "long piece" which is placed within the
stem as being made of clay or asbestos, I do not propose to confine myself to these
substances but may use any suitable material or substance which while being
capable of intercepting the nicotine, shall at the same time be capable of being
thoroughly and completely cleansed from the same by means of heat applied.
I do not propose to limit myself in any way to the materials in which I may
manufacture the remainder of my pipe or to the particular shape or fashion of my
pipe.
The advantages of my improved pipe are that it is very cool in smoking, and
there is no chance of nicotine entering the mouth of the smoker, it is also easily
cleaned and should the interior clay piece loose its virtue by accident, it can
easily be replaced with another one at a nominal cost, or the pipe could be smoked
without it altogether.

Improvements in Pipes for Smoking Tobacco.
I, THOMAS PARRY of Hillcroft Silverdale, Sydenham Gentleman 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 my invention is to form a pipe which shall prevent nicotine being
drawn into the mouth while being smoked. My invention chiefly relates to that
part of the pipe known as the stem and which extends between the bowl and the
mouthpiece.
The bowl of my improved pipe is formed and fashioned in the same way as an
ordinary pipe, and terminates at the bottom in the usual small aperture leading out
to the stem.
On reaching the stem, this small aperture or passage widens out, and the
remainder of the stem consists of a hollow tube at the end of which is placed the
mouthpiece of the pipe.
This mouthpiece is attached to the stem by any ordinary tight fitting joint or
any other approved means.
The mouthpiece is formed for a short distance near the joint in the manner of
a tube like the stem, and then the hollow is gathered together by the sloping sides
and a small passage is formed in the remainder of the mouthpiece similar to that
found in ordinary mouthpieces.
I now arrive at the principal part of my invention which consists of a long piece
of clay, asbestos, or other absorbent substance formed on its outer surface or surfaces
so as to just comfortably fit into the tube which forms the stem of the pipe, and
of sufficient length so that when placed as far as possible in this stem, it shall
project out a short distance, such projecting portion being covered by the mouth-
piece when secured thereon.
This piece of clay or asbestos is pierced longitudinally by a series of small
straight holes which are circular in diameter, and through these holes passes the
smoke from the bowl of the pipe to the mouth of the smoker.
As a modification of my invention, I may groove the outer surface the clay
piece either with longitudinal grooves or screw-formed grooves in combination with
one or more longitudinally perforated passages as hereinafter illustrated by Figs. 3
and 4 on annexed sheet of drawings.
The object of this clay piece aforementioned is to intercept the nicotine.
When the pipe becomes foul from continued use the mouthpiece is taken off and
the "clay piece" easily withdrawn (as it is found to project slightly from the
stem) and it can then be purified and made clean by burning in a sufficient heat
and afterwards replaced within the stem, and the mouthpiece added when my
improved pipe will again be found to be sweet and clean.
Although I have hereinbefore referred to the "clay piece" as the inserted
portion, I do not propose to restrict myself solely to the use of clay for the
manufacture of this piece, but may use asbestos when it is required to purify
the piece" by fire or again when it is not proposed to trouble about cleansing the
"piece but merely to replace the foul "piece" with a clean one, then I may use
any absorbent cellulose substance such as paper pulp or the like.
The advantages of my improved pipe are that it is very cool in smoking, and
there is no chance of nicotine entering the mouth of the smoker, it is also easily
cleaned and should the interior clay piece loose its virtue by accident, it can easily
be replaced with another one at a norainal cost, or the pipe could be temporarily
smoked without it altogether.
In order that my invention may be the more fully understood, I will now proceed to

page_text: describe the sheet of drawings hereunto annexed, like letters of reference indicating
corresponding parts throughout.
Fig. 1 is a geometrical side elevation of my improved pipe.
Fig. 5 is a geometrical longitudinal section through the entire length of the
pipe.
Figs. 2, 3, and 4 are views of the "clay piece" including modifications of same.
In Fig. 1, A is the bowl of pipe, B the stem, and C the mouthpiece.
"
In Fig. 5 the blackened portion marked D, is the absorbent "clay piece'
shewn here in section after the style of the screw groove shewn in the view
marked Fig. 4.
Fig. 2 shews the "clay piece" with an even surface but pierced longitudinally
with a number of holes or channels marked e.
Fig. 3 is a modification of the clay piece Fig. 2 the outer surface is here shewn
traversed with longitudinal channels or grooves f.
Fig. 4 is a still further modification of the clay piece only the outer surface is
traversed by screw formed grooves f'.
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) An improved pipe formed in two pieces as shewn in Figure 1 and provided
with a removable absorbent portion D, shewn in section in Figure 5 all as herein-
before set forth in this Specification and illustrated by the accompanying drawings.
(2) In a tobacco smoking pipe the combination of the bowl, stem, and mouthpiece
with absorbent portion D, as illustrated by Figure 2.
(3) In a tobacco smoking pipe the combination of the bowl stem and mouthpiece,
with the absorbent portion D as illustrated by Figure 3.
(4). In a tobacco smoking pipe the combination of the bowl, stem and mouthpiece
with the absorbent portion D as illustrated by Figure 4.
