Improvements in Tobacco Smoking Pipes to facilitate the Easy and
and
Rapid Cleaning of the same and to prevent Nicotine Moisture
from being Drawn into the Mouth when Smoking.
"
or
I, JOSEPII ALBERT HALL, of Holme Villa," Alghers Road, Loughton, in the
County of Essex, Gentleman, 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 certain improvements in tobacco smoking pipes of
any and every shape or design and of any and every kind of wood meerschaum,
clay asbestos vulcanite, bone, horn, or other substance of substances, material oi
materials of which pipes are or can be made.
and
These improvements facilitate the easy and rapid cleaning of tobacco smoking
pipes and prevent nicotine moisture from being drawn into the mouths of
the smokers thereof.
ог
The improvements consist of:-
(1) specially designed head or bowl (hereinafter called "the head") which is
made in two separate and detachable paits, the upper part having a thread or
screw cut in or on its outside sui face and the lower part a thread of screw cut in
or on its inside surface by which the parts are screwed and fitted together The
two parts are of such relative sizes and shapes that a chamber is left between
them when screwed together which forms a tiap where the nicotine collects o1
into which it falls through a hole or holes in the bottom of the upper part in
which the tobacco is placed for smoking When the pipe is in use the smoke
passes into the said chamber or trap and from it thiough a hole or duct or
passage into the stem of the pipe.
The lower part of the head has a hole dilled or bored through its front
(opposite the end of the stem) and the upper part has a cut on notch made on
its lower outside so that by partially unscrewing o evolving the upper part
until the said cut or notch is opposite the hole drilled oi bored through the font
of the lower part a duct or passage 18 made to such hole and any nicotine which
may have collected in the chamber or trap between the two parts may be blown
out through same This is one method which may be adopted for cleaning the
nicotine out of the head of the pipe Alternatively with that method and for
more perfect cleaning the upper part can be unscrewed and detached from the
lower part and open and easy access is then obtained for the purpose of cleaning
the nicotine out of same
(2) stem with a chamber or trap therein specially designed to catch any
nicotine which may escape from the head and also to prevent the passage of any
moisture from the stem into the head. The end of this chamber of trap through
which the hole or duct or passage is bored or made from the stem into the head
is for the latter purpose cut or made at an acute angle fiom its centie all'iound
to the side or sides of the chamber or trap.
(3) A mouthpiece with a chamber or trap specially designed to catch any
nicotine or moisture which may escape from the stem of the pipe. This chamber

page_text: or trap 18 so constructed that it practically forms two chambers one larger than
the other, the smaller being the one through the end of which the bore or hole
18 made or drilled to the end of the mouthpiece from which the smoke passes
or is drawn into the mouth The end of the chamber 18 so cut that it forms all
round from the centre bore or hole an acute angle to the side or sides of the
chambei From the opposite end of this smaller chamber an oblique cut 18
made all round to the side o1 sides of the larger chamber so that the end
which it forms of the latter chambei 18 an acute angle to its side or sides.
Alternatively the chamber or tiap may be made so as to form practically three
or more chambers instead of two similar in design to those above described
Or it may be made as one chamber without any divisions or sub-chambers
but with an end similar to that which the smaller one, has in the above descrip-
tion.
(4) A specially-designed plug which fits into the stem and mouthpiece of the
pipe and connects them together and which can at any time be detached there-
from for cleaning or any other purpose
This plug has a thread or screw cut on or in its surface at one end to fit into a
thread or screw cut or made on or in the inside sui face of the stem at the end
of the chamber or tiap made therein.
.
At its opposite end the plug has a similar thread or screw cut or made on or
in its surface to fit into a thread or sciew cut or made on or in the side surface
of the mouthpiece at the end of the chamber or tiap made therein.
The ends of the plug are cut from then centres to the ends of the threads or
BCrews at obtuse angles to the sides of the plug so that when it is fitted into
the stem and mouthpiece one of its ends forms all round from its centre an acute
angle to the side or sides of the chamber on trap in the stem and the other end
(of the plug) forms all round from its centie an acute angle to the side or sides
of the chambei oi trap in the mouthpiece
A hole is bored or drilled horizontally though the centre of the plug and a
tight-fitting tube 18 inserted therein of such length that it extends beyond the
plug at both ends so that when the plug is screwed into the stem and mouthpiece
of the pipe one end of the tube projects into the chamber or tiap in the stem
and the other end into the chamber or trap in the mouthpiece, the ends being
shorter than the chambers or traps into which they respectively project Alter-
natively the plug may be constructed with the tube as part of itself but so that
the ends project as above described.
and
The ends of the tube are made smaller in their external diameters than the
internal diameters of the chambers or traps into which they project in order to
prevent any nicotine moisture from passing or escaping from either chamber
or trap into the other.
or
But in order that this invention may be more clearly understood reference is
made to the drawings herewith.

The best arrangements for carrying out this invention have been described
above but such invention would still be valuable if the whole of the arrange-
ments were not strictly adhered to in all their details. The head for instance
might be made as described but combined with other styles or forms of stem
and mouthpiece Or the head and the stem might be made as described but
combined with another style of mouthpiece Or the head and the mouthpiece
might be made as described but combined with another style of stem. Or the
stem and the mouthpiece might be made as described but combined with another
style of head Oi the stem might be made as described but combined with other
styles of head and mouthpiece Or the mouthpiece might be made as described
but combined with other styles of head and stem. Or the chamber or tiap in
the mouthpiece instead of being divided into the two parts or chambers F and D
might be made into three or more parts or chambers of sizes increasing from
the inside end of B to GG with an acute-angled cut at the end of each of the
parts or chambers similar in design to that at the end of each of the parts or
chambers F and D in the drawings herewith described above Or the chamber
or tiap in the mouthpiece might be made as one chamber without any divisions
or sub-chambers but with an end similar to that which the smaller one F has in
the diawings herewith described above Or the ends of the chambers in the
stem and mouthpiece and the ends of the divisions or sub-chambers of the
chamber in the mouthpiece might be cut at night angles to the sides of such
chambers instead of being cut at acute angles as shown in the drawings herewith
described above Or the end of the chamber in the stem might be cut at an
obtuse angle all 1ound from N to the side or sides of the chamber instead of being
cut at an acute angle as shown in the diawings herewith described above. Or
the two parts of the head might be connected together otherwise than by the
threads oi screws for that purpose described above They might be made so that
the upper part would push and fit tightly into the lower part or in some other
manner but so that they might be disconnected and detached at any time for
cleaning or any other purpose. Or the plug and stem or the plug and mouth-
piece might be connected together otherwise than by the threads or screws
described above for that purpose. They might be made so that the plug would

page_text: push and fit tightly into the stem at one end and the mouthpiece at the other
or in some other manner but so that they might be disconnected and detached
at any time for cleaning or any other purpose. Or the plug might be made with
the ends of the tube longer or shorter so as to project further or less into the
chambers or traps in the stem and mouthpiece Or the plug might be made
with the tube only projecting at one end into the chamber or trap of either
the stem or mouthpiece.
It is not intended that the invention should be applicable to pipes only of the
shape or pattern shown in the drawings but also to pipes of any other shape or
pattern.
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 head or bowl of the pipe made in two separate and detachable parts
(whether they be joined or attached together by screwing or pushing one part
into the other or in any other manner) with a chamber between the two parts and
a hollowed-out nicotine cup or trap in the lower part for the purposes specified
and substantially as described above and shown in the drawings herewith.
(2.) The combination of the hole through the front of the lower part of the
head with the cut or notch on the under side of the upper part for the purpose
of blowing out and removing the nicotine and cleaning the head of the pipe sub-
stantially as described above and shown in the drawings herewith.
(9.) The chamber or trap in the stem with the end thereof cut all round from
the centre at an acute or any other angle to the side or sides of the chamber or
trap for the purposes specified and substantially as described above and shown in
the drawings herewith.
(4) The plug with the tube or end of tube to project into the chamber or trap
in the stem substantially as described above and shown in the drawings herewith.
(5) The combination of the plug with the stem so as to form or complete the
formation of the chamber or trap in the latter with the tube or end of tube
projecting from the plug into the centre of the chamber or trap but not touching
the side or sides thereof substantially as described above and shown in the
drawings herewith
(6) The plug with the tube or end of tube to project into the chamber or trap
in the mouthpiece substantially as described above and shown in the drawings
herewith.
(7) The combination of the plug with the mouthpiece so as to form or complete
the formation of the chamber or trap in the latter with the tube or end of tube
projecting from the plug into the centre of the chamber or trap but not touching
the side or sides thereof, substantially as described above and shown in the
drawings herewith.
(8.) The chambers or traps F and D in the mouthpiece with the end of each
cut all round from the centre to the side or aides at an acute angle and, if more
than two such chambers or traps, with the end of each, or, if only one chamber
or trap (without divisions or sub-chambers), with its end cut similarly at an
acute angle to the side or sides of the chamber or trap substantially as described
above and shown in the drawings herewith, and, alternatively with the end of
the chamber or trap or each and every or any chamber or trap out at a right
angle all round from the centre to the side or sides thereof.
