TRUY IDIONAL SPECIFICATION.
Improvements in Pipes for Smoking Tobacco.
I, EDWIN BARRON, of. 39, Esmond Road, in the County of Middlesex, Agent,
do hereby declare the nature of this invention to be as follows:-
This invention relates to Improvements in Pipes for Smoking Tobacco.
In carrying out my invention I form the stem of the pipe with a number of
perforations or bores instead of one only as hitherto, the stem of the pipe being
connected to the bowl in any usual manner. The opening from the bowl is in
communication with only one of the perforations in the stem by which means the
smoke has to pass through the length of the stem then back through one or more
of the other perforations and then to the mouthpiece through the remaining
perforation which is in communication with the bore of the stem.
By this means it will be obvious that the smoke from the bowl before it reaches
the mouth of the smoker will have to pass three times through the length of the
stem whereby it becomes cooled and a considerable portion of the moisture and
uicotine will be deposited in their passage in the first perforation and be thereby
prevented from entering the mouth of the smoker.
In order to allow the proper adjustment of the stem to the bowl and mouthpiece
so that the perforations may correspond with the respective openings, the ends of
the stem are halved or dovetailed, the bowl and mouthpiece being corresponding
halved or dovetailed.

COMPLETE SPECIFICATION.
Improvements in Pipes for Smoking Tobacco.
I, EDWIN BARRON, of 39, Esmond Road, in the County of Middlesex, Agent,
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:
This invention relates to Improvements in Pipes for Smoking Tobacco, and has for
its object to cause the smoke to pass several times the length of the stem of the
pipe in its passage from the howl to the mouth-piece.
In carrying out my invention I form a number of passages or bores instead of
one only as hitherto.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a longitudinal section of a pipe constructed according to
and,
my
invention;
Figures 2 and 3 are sections on the lines 2-2 and 3-3 respectively of Figure 1:
Figure 4 is a plan view of the mouth-piece detached.
a is the bowl of the pipe, 6 is the stem, and c is the mouth-piece, all of which
parts may be of any suitable shape or construction.
The stem is bored parallel throughout its whole length and the mouth-piece
has attached to it a shank d adapted to fit within the bore of the stem.
[Price 8d.]
This shank

page_text: has formed in it a series of longitudinal grooves the number of which varies
according to the number of times which it is desired to cause the smoke to travel
to-and-fro in the stem before it reaches the mouth-piece.
As shewn in the drawing I have represented the said shank as being formed
with three grooves indicated by the letters e, e¹, e'; only one of these grooves,
viz., the groove e extends quite to the end of the shank, the others e', e terminate
at some little distance therefrom.
As shewn in Figures 2 and 4 the grooves e, el are placed in communication
through a notch fand the grooves e¹, e are placed in communication through a
notch g, whilst the groove e communicates with the bore of the mouth-piece
through a passage h. By this arrangement it will be obvious that the smoke in
passing from the bowl to the mouth-piece will have to pass three times through the
length of the stem, viz. :-first along the stem through the passage e thence
back through the passage e¹ and thence again forward through the passage e. By
thus causing the smoke to travel several times through the stem it becomes cooled
and a considerable portion of the moisture and nicotine is deposited, thereby
preventing them from entering the mouth of the smoker.
Instead of providing the mouth-piece with a grooved shank as hereinbefore
described, I may form a series of passages in the stem which in this case is made
detachable from the bowl, one of the said passages communicating with the mouth-
piece and another with the bowl.
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 pipe for smoking tobacco having in the stem a series of passages which
communicate with each other and one of which is in communication with the bowl
and another with the mouth-piece of the pipe, whereby the smoke, in passing from
the bowl to the mouth-piece, will be caused to travel several times the length of
the stem, substantially as described.
2. In a pipe of the kind herein before described a mouth-piece having connected
to it a shank provided with a series of longitudinal grooves which communicate
with each other and one of which extends to the end of the said shank whilst another
is connected with the bore in the mouth-piece, substantially as described.
