Foreman Engineer, No. 1 Alexandra Crescent, Leels do hereby declare the nature
of this invention to be as follows:-
The improvement consists of an air passage through at the head of the pipe,

COMPLETE SPECIFICATION.
Improvement in Tobacco Pipes.
We, SAMUEL HALL, of No. 5 Alexandra Crescent, Engineer, and JOHN HALL,
of No. 1 Alexandra Crescent, Foreman Engineer, both in Leeds in the County of
York, 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 tobacco pipes and cigar and cigarette holders, and
has for its object to prevent as far as possible the accumulation of moisture and
nicotine in the stems of pipes or the like and the consequent fouling of the same.
According to our invention we provide a small opening in communication with
the stem of the pipe, as we have found by experiment that the vapours carrying the
moisture and nicotine will to a great extent be discharged from the pipe through
this opening owing to the breath of the smoker, and that the fouling effects of any
moisture or nicotine which may be deposited will be to a great extent neutralized
by the pure air drawn in through the said opening when smoking without having to
pass through the tobacco.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 represents a side elevation;
Figure 2 an end view; and
Figure 3 a longitudinal section of a tobacco pipe constructed according to our
invention.
a indicates the bowl of the pipe, 6 the stem, and c the mouth-piece, the said parts
being of ordinary construction.
d is a cap or plug of bone, vulcanite or other suitable substance which is
arranged in conjunction with a chamber or reservoir e forming a continuation of
the bore of the stem, and fis our opening or aperture formed through the end of
the cap d and serving when the smoker breathes into the pipe to allow the escape
of some of the vapours therethrough in the manner hereinbefore indicated and
to allow of air being drawn in when smoking without passing through the
tobacco.
The cap or plug d is preferably provided with a nozzle g to prevent any moisture,
which may accumulate in the chamber e, from passing to the opening f.
If desired this plug may be made of ornamental shape, for instance, it may be
formed to represent a head, the aperture for the escape of the vapours being formed
at the mouth of the said figure.

page_text: Although we have described our invention as applied to a tobacco pipe it is
obvious that our improvement is applicable to cigar and cigarette holders and
especially to those which are made somewhat in the form of a pipe, that is to
say, which are provided with a socket at one side of the stem designed to receive a
cigar or cigarette.
In practice we have found that our aperture is advantageously made of a
size corresponding with a wire of No. 22 Birmingham wire gauge.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
(1.) A tobacco pipe or the like provided with a small aperture such as f, substan-
tially as described.
(2.) The improvement in tobacco pipes or the like, substantially as hereinbefore
described and illustrated in the accompanying drawing.
