PROVISIONAL SPECIFICATION.
Improvement in Tobacco Pipes.
I DANIEL LIST BRAIN, Lt. Col. retired, of Highfield, Ryde, I. W. do hereby
declare the nature of this invention to be as follows:-
For enabling a pipe to be cleaned without use of pipe cleaner, and to prevent
moisture entering either into the mouth or bowl, I divide a pipe of ordinary shape
laterally into two portions. The lesser portion consists of the inner portion of the
bowl with the upper portion of the stem. The former when in position fits wedged
shaped into remaining portion of bowl by dividing planes being in direction of the
radii of cylinder of bowl; its attached upper portion of stem can be solid. In
lower portion of stem a tube for smoke to pass is formed and about the central
portion a depression to form reservoir is formed with extremities curved respectively
towards bowl & mouth piece to retain the moisture. The two portions of pipe are
kept together when for use by the ferrule of mouthpiece fitting over them, to
additionally retain these in position a spring might be attached to under portion of
ferrule having a stud at other extremity to enter a corresponding indentation in
stem; the stem can be of elliptical section and the bowl if necessary thicker towards
mouth piece.

Improvement in Tobacco Pipes.
DANIEL LIST BRAIN Lt. Col., retired, Highfield, Ryde, I.W. 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:-
I divide a pipe of ordinary shape either with straight or curved stem, laterally
in two portions as A & B. Fig. I. The removeable half or portion A fitting when
united for use wedge shaped into remaining part B. Plan of rim of bowl shewing
the connexion is given in Fig. II.
The central portion of lower stem is deepened as at (e. f.) to form a chamber or
reservoir, to receive the tobacco juice or moisture produced by smoking; in order
to prevent this from escaping into the smoke tube its sides and extremities slope
upwards and inwards as at (e. f.) the smoke tube being slightly inclined on either
side towards the chamber, shewn in Fig. III.
Varied transverse sections of stem are shewn at (c. d.). In one the upper part
of stem has a flat surface, in the other, and preferably for closer junction, a wedge
shaped section; (a. b.) shews transverse section of chamber. In (Fig. IV.) repre-
senting a bowl with curved stem the chamber is deepened downwards towards the
bowl, more perfectly prevent moisture escaping into it.
A modification of the above design consists in leaving the bowl entire, and
making the upper portion of the stem or part of it removeable, as shewn in
(Figs. III. IV.) where A is the removeable part, the extremity (a) towards the
bowl being bevelled or tongue shape to enter, when parts are together into a
corresponding slot or bevel in remaining portion of pipe."
When for use the two parts of divided stem, or stem with bowl, are retained in
close junction by their extremities fitting into a ferrule (Fig. VI.). To more
effectually prevent these from slipping out of ferrule, an underneath spring can be

page_text: attached to latter, with its free end (e), in its normal state made to enter a slot
formed in the stem.
In a similar manner as described above for the stem I can divide the mouth piece,
or that portion of it nearest to the bowl, which enters the ferrule (Fig. V.) forming
a chamber below the removeable portion, and the parts being kept together as for
the stem. This divided mouthpiece can be used with an ordinary shaped pipe; or
in combination with either of those above described.
This design for divided pipes is preferably to be made of composition by means
of moulds.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. The division of a pipe into two portions, for the purpose of removing one
portion, in order that incrustation or moisture might be taken away without the
aid of a pipe cleaner, and more thoroughly, as the entire interior then becomes
exposed.
2. The division of the stem only, or mouthpiece, into two portions, for the above
mentioned end to be attained.
3. The construction of a chamber or reservoir, as herein described, in the stem
or mouthpiece, for the reception of moisture, so designed as to prevent its escape
into the smoke tube or bowl of a pipe.
