We SAMUEL REEVE of 16 Ariel Road West Hampstead in the County of Middlesex,
Engineer, CHARLES EDWARD RATCLIFFE of 10 Berners Street also in the County of
Middlesex, Engineer, and JAMES BRACKENBURY DAVIS of 2 Grenada Terrace
Stockwell Park Road Brixton in the County of Surrey, Draughtsman, do hereby
declare the nature of this invention to be as follows:-
The object of the invention is to so modify the construction of tobacco smoking
pipes as to render the smoking of tobacco therein more enjoyable and less likely to
injure the smoker.
For this purpose we so construct the parts of the pipe bowl or adjacent parts or
both that the oil condensed or foul or liquid matters are intercepted and prevented
passing to the mouth of the user.
This we effect by means of a bowl formed in one with the pipe or a bowl of clay or
other suitable material separable therefrom to hold the tobacco provided with a hole
or with holes at the sides or lower part through which the smoke is drawn by the user
drawing in the ordinary way at the mouth piece end of the stem or tube but the
smoke instead of passing direct has to take a more or less devious course from or after
leaving the lower side of the bowl either over a surrounding thin annular curtain or
wall of corrugated metal or other material closed below but open above, which is
intervened between the tobacco bowl and the outer wall of the pipe bowl or holder
and there is provided an opening in the outer holder closeable by plug or screw for
removal of accumulated liquid or the like end may be attained by making the passage
or passages or channel or channels in an inclined direction upward and outward.of the
bowl (when held mouth upwards) or the interception may be attained with or without
the surrounding screen or curtain or inclined passages, the alternative therefor, by
means of an enlarged compartment or passage in the stem into which from and carried
by the mouth piece projects a smaller tube having side or other holes for draught of
sinoke and with or without annular enlargements and this smaller tube may be utilised
to form the stem for a ram head or piston which normally lies ensconced out of the
way below the inner bowl but which being drawn out serves as a scraper or means of
collecting and withdrawing accumulations of condensed matters and the like present
in the larger diameter tube.

page_text: A convenient form of construction with a curtain or screen around the bowl is to
form the tobacco holder with say, 1, 2 or 3 holes for,draught of smoke and below with
a tubular projection internally threaded or bushed to receive a screw or plug and
loosely around this tobacco holder but fitting tightly, the tubular projection is a corru-
gated or recessed curtain or screen of thin metal or other suitable material or this
screen may be of thimble form and lie below the bowl, or this double bowl may be
dispensed with and the bowl formed in the simplest ordinary fashion attaining the
interception entirely in the stem.
This bowl and its encircling screen are inserted into the casing or outer bowl which
is formed to the upper part of the tobacco receptacle and the tubular projection at the
lower part-a screw or plug passed thereinto holding the whole together and closing
the bottom opening if one is used.
The user drawing smoke or air through the pipe stem in the curtain modification
causes a current to pass through the bowl into the recess between the bowl and the
curtain which flows up over the curtain down between it and the casing of the bowl
and thence by the stein is the smoke drawn off and by the rammer and rod when
employed the foulnesses are capable of being drawn away.
A similar effect takes place when the inclined passages are used instead of a fixed
screen or removeable thimble shaped inner bowl.
A corresponding effect also is attained by the stem intercepter when used in place
of or as an accessory to the bowl interception.
The tubular projection of the tobacco bowl and the screw or plug applied thereto
may be dispensed with, and any accumulation intercepted by the intermediate
encircling curtain may be removed after withdrawal of the tobacco receptacle, leaving
no substantial divergence from the external appearance of an ordinary pipe bowl, or
the effect of the curtain practically may be attained by the double chambered stem
and the removal of foul accumulations be effected by the rammer head.
In some cases we apply on the stem carrying the piston or plunger a brush or
brushes or fibrous fringe which serves to filter the smoke and detain or intercept
liquid condensed or impurities passing or flowing. The fibres of the brush or
encircling fringe may be of asbestos or other suitable cleansible material of sufficiently
durable character and the withdrawal of the inner stem permits of washing or other
purification being effected.
The fringe may be applied to the stem helically spirally annularly or otherwise.
Another part of our invention has reference to the production of a pipe which
shall as regards the stem or part thereof, either jointly with the base of the bowl or
not be formed of meerschaum externally or throughout the thickness of that part and
be jointed on to a "brier " or briar or like wood or other bowl and amber stem or
like stem of other material or materials.
The meerschaum portion may be merely a sleeve slidden on a wooden hollow core
or stem or provided with perforations giving access to the meerschaum or be other-
wise jointed to the parts and the meerschaum when well coloured can be removed to
another set of fittings when the original has been worn or injured.
By these means the smoke is separated from any "oil" produced from the
combustion of the tobacco and the liquid is retained by the curtain or equivalent
intercepter and any saliva passing down the stem from the user is intercepted from
the bowl and tobacco and can be readily removed.

DESCRIPTION OF THE DRAWINGS.
Figure i is a longitudinal section of a tobacco pipe constructed according to one
modification of this invention.
a is the bowl proper or tobacco holder during ignition and this may be of clay, 4
meerschaum wood as one
..
Tongitudinal section of a tobacco pipe constructed according to one
modification of this invention.
a is the bowl proper or tobacco holder during ignition and this may be of clay,
meerschaum wood or any suitably refractory material.
is the case or supporting part to which the bowl a is secured by cementing
pinning screwing or otherwise.
c is an intervening shell or thimble d is the mouth piece screwed into bat b, but as
will be apparent the parts and d-may be in one e is a short tube having contracted
ends ee, small openings e³ et being provided. e is a ball valve for which the
contractions of the tube e¹ or e serve as a seating according as the pipe be held as in
the illustration or with the bowl a in inverted position.
As illustrated the valve will by seating at the bottom stop outlet of liquid to any
material extent but when the bowl is inverted and the mouthpiece strongly blown

page_text: into, the rush of air through the bore 62, the opening e, the tube e and the exit
opening that ensues carries with it oil or condensed or fouling matter.
The arrows indicate the course taken by the smoke when the pipe is in ordinary
use that is to say it leaves the bowl a at the orifice or orifices a¹ travels upward and
then downward and outward by the pipe stem bore to the smoker.
Fig. 2 is a slightly modified form of pipe, the valve being in this case, a screw
plug screwed into a bushing g which is threaded into the bottom neck of the thimble
or curtain shell c so as to serve as a means of holding the same and the bowl a in
position removably and also fas a closer to the passage a² through the bowl socket
and exit formed by the removal of f.
Fig. 3 is another slightly modified form of the pipe shewn by Fig. 1 in cross
section and Fig. 4 the corresponding longitudinal section.
Fig. 5 shews in longitudinal section and Fig. 6 in cross section the bowl parts of a
similar pipe omitting the outlets e or fand providing a small orifice h which may be
closed by a little spigot if desired.
Fig. 7 shews another modification in which the stem bore 62 is larger and the
mouth piece has a prolongation which at is formed to approximately fit and wipe
out the bore of the stem as it is being withdrawn, whilst by being bored at d¹ and
cross bored at d² this mouthpiece serves as an auxiliary intercepter of the foul
condensations or deposits in the tube of the stem.
с
In this Fig. 7 the inner thimble c is suppressed and its equivalent is attained by the
upwardly inclined passages a¹ and cross passages at d² cooperating to prevent egress
of liquid matter. Fig. 8 shews curtain of Fig. 2 separately. Fig. 9 a modified
ball valve e.
We are aware that it has been proposed to construct a pipe with a ball valve com-
municating directly with the interior of the bowl from the exterior air but we make no
claim thereto, or to the use of such a valve for a pipe for tobacco smoking except in
combination with our described means of intercepting condensed matters.
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. In a pipe for use in smoking tobacco the various combinations of parts arranged
substantially as and for the purpose set forth.
2. A tobacco pipe constructed or arranged with an intercepting thimble or curtain
shell as set forth in respect of Figures
to 6.
3. A tobacco pipe arranged or constructed as set forth in respect of Figure 7.
