1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
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 the invention is to provide a tobacco pipe of ordinary length and
capable of being carried in a pocket case, wherein all the advantages of a pipe with a
lengthened stem in the way of cooling the tobacco smoke is attained; the smoke being
caused to pass through tubes which traverse the stem three times before being drawn
into the mouth of the smoker through the mouth piece, as hereinafter more particularly
explained.
The drawing represents an enlarged erspective view of this improved pipe the
upper half of mouth piece, stem, neck of bowl and bowl having been cut away so as
to exhibit this device.
In this figure A is the bowl of the pipe partly broken away so as to show the orifice
at a in the bottom of the bowl through which the smoke is drawn into the stem. B is
the neck of the bowl the end of which at b butts up against the end of the stem D.
This joint at 6 is covered and held together by the ferrule C which is attached to the
stem D. Instead of the stem being fastened to the neck of the bowl by a ferrule it
may be screwed on the neck in the usual manner.
E is a tube preferably of metal closed at the end nearest to the bowl and rigidly
attached to the neck of the bowl B in a recess formed therein; the end which projects
beyond the neck of the bowl being fitted into a recess or enlargement at e of the smoke
tube No. 3 and is cut out at the end of the stem. f is a small tube open at both ends
which fits tightly into an enlargement of the smoke tube No. 1 at the end of the
neck of the bowl; the end which projects slightly beyond the end of the bowl being
adapted to fit into an enlargement of the smoke tube No. 1 at the neck end of the stem.
This small tube f is here placed to prevent any leakage of smoke passage No. 1 at the
joint covered by the ferrule C.
F is a mouth piece preferably of amber with screw-g fastened thereto in the usual
manner and adapted to screw into the screw recess h formed at the mouth-piece end

page_text: of the stem D. The inner portion of the stem surrounding this screw g
cut away
so as to form a circular passage way for the smoke from smoke-passage No. 1 to
smoke passage No. 2 at the opposite side of the pipe stem; the end of the mouth
piece F when screwed down on the stem forming a covering for this circular smoke
passage. The stem and neck of bowl are preferably eliptical in shape as indicated so
as to afford room for the three smoke-passages Nos. 1, 2 and 3. The end of smoke
passage No. 2 near the joint which is covered by the ferrule is slotted or open so as to
afford a smoke passage into smoke tube No. 3 through a hole m formed in the side of the
tube E.
When the smoker uses this improved tobacco pipe the smoke is drawn from the
bowl along smoke passage No. 1 in the direction of the arrow head thence across to
smoke tube No. 2 by the circular passage k thence along smoke passage No. 2 in the
direction of the arrow head through the hole m into smoke passage No. 3 and through
smoke passage No. 3 in the direction of the arrow head through the mouth piece F
into the smoker's mouth. By the time the tobacco smoke has reached the smoker's
mouth it has traversed the length of the stem three times and is quite cooled down so
as to afford all the advantages of a pipe with a long stem with none of the dis-
advantages, as this improved pipe can be handily carried in a coat pocket with or
without a case the stem not being at all in the way or clumsy to carry. This improved
pipe can also be readily cleaned by taking it apart and cleaning the stem with the
three smoke passages the mouth piece and bowl in the usual manner. The inside of
the ferrule is also readily accessible for cleaning. The recess P in the tube E forms a
reservoir for the saliva so that the saliva from the mouth cannot wet the tobacco in the
bowl of the pipe.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondents and in what manner the same
is to be performed, I declare that what I.claim is :-
1. A tobacco pipe formed of mouth piece stem and bowl in which when the pipe is
in use the tobacco smoke is caused to traverse three or more times the length of the
stem substantially as described and for the purpose specified.
2. An improved tobacco pipe in which the stem is perforated with three or more
smoke passages in combination with a mouth piece and bowl passages for the smoke
being formed between the outer tubes and between an outer tube and the central tube
from which it is drawn through the mouth piece into the mouth of the smoker sub-
stantially as specified.
3. In an improved tobacco pipe the combination with stem D pierced with smoke
passages Nos. 1, 2 and 3 of mouth piece F smoke passage k smoke passage m formed
in the tube E the ferrule C neck of bowl B pierced with smoke tube leading to smoke
passage No. 1 in stem and pipe bowl A substantially as described and specified.
4. In an improved tobacco pipe the mouth piece F detachably secured to stem D
and stem D detachably secured to neck B of the pipe bowl the stem D having three
smoke tubes traversing its length with smoke passage k between two of the tubes and
smoke passage m therefrom to the smoke tube leading to the mouth piece forming a
continuous passage way for the smoke from the bowl of the pipe to the mouth of the
smoker thrice traversing the length of the stem substantially as specified.
5. In an improved tobacco pipe the combination with the stem D pierced with
smoke passages Nos. 12 and 3 of mouth piece F smoke passage k smoke passage m
formed in tube E pipe f saliva reservoir P the ferrule C neck of bowl B pierced with
smoke tube and pipe bowl A substantially as described and specified.
