An Improvement in Tobacco Fipes.
I WALTER BROADHURST DUTTON of 63 Worfield Street Battersea in the
County of London, Solicitor's Clerk do hereby declare the nature of this invention
to be as follows :―
The stem of the bowl of the pipe having a reservoir or hole running almost the
entire length of same and ending behind the small hole leading to the tobacco
well. The mouthpiece having a continuation to extend to the end of reservoir
and having fixed at the extreme end a piece of rubber in the shape of a semi-globe
or half-sphere exactly fitting the reservoir and which rubber when the mouthpiece
is fixed in the pipe rests behind the hole leading to the tobacco. The mouthpiece
and continuation at the end of which the rubber is fixed is made in one piece.
By withdrawing the mouthpiece the rubber is drawn along the reservoir thus
clearing it of any saliva or nicotine which may have collected. This being quickly
and simply done in one motion I claim that this is a most effective method of
preventing nicotine from forming in any quantity in the pipe and for keeping the
pipe clear from saliva.

COMPLETE SPECIFICATION.
An Improvement in Tobacco Pipes.
I WALTER BROADHURST DUTTON of 63 Worfield Street Battersea in the
County of London, Solicitor's Clerk do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
The stem of the bowl of the pipe has a reservoir or hole A (as shewn in the
drawing annexed hereto) running almost the entire length of the stem and ending
behind the small hole B which leads to the tobacco well C. The mouthpiece D
has a continuation E which extends to the end of the reservoir A. This
continuation E has fixed at the end a piece of rubber F which is in the shape of
a semi-globe or half sphere and which piece of rubber exactly fits the reservoir A
and when the mouthpiece D is fixed in the stem of the pipe, the piece of rubber F
rests at the end of the reservoir A behind the small hole B. The mouthpiece D
and the continuation E are made in one piece. By grasping the mouthpiece D and
withdrawing the same the piece of rubber F is thereby drawn along the reservoir A
thus clearing it (the reservoir A) of any saliva nicotine or other obnoxious matter
which may have collected therein. As the process of cleaning the reservoir A may
be frequently performed on account of its simplicity and expedition it will be easily
seen that by keeping the reservoir A in a clean state and also on account of the
arrangement of the draught hole G, the mouthpiece will be practically free from
nicotine &c.

page_text: 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 improvement in the process or means of withdrawing or returning the
piece of rubber F along the reservoir A the said improvement consisting in the
construction of the mouthpiece D and the continuation E in one piece (as shewn
in the drawing annexed hereto) thereby enabling the piece of rubber F to be
withdrawn or returned along the reservoir A in one action and without soiling
the hands.
(2.) An improvement in the shape or form of the piece of rubber-the said
improved shape or form being that of a semi-globe or half-sphere as hereinbefore
referred to, and shewn in section, F in the drawing annexed hereto. Such
improved shape or form of the said piece of rubber enabling the same after being
withdrawn to be easily returned along the reservoir A.
