PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Tobacco Pipes.
I, WILLIAM SUTCLIFFE of 12 Dale Street, Sowerby Bridge, in the County
of York Joiner, do hereby declare the nature of this invention to be as follows:-
This invention has for its object a pipe that will separate the nicotine so that the
smoker can smoke the entire charge without the smoke tasting strongly.
The invention consists essentially in introducing the system of separating by
vortex similar to the well known Tornado dust collectors, of P. van Gelder of which I
am the manufacturer.
I form the pipe with a bowl, let into a second hollow metallic bowl. This
metallic bowl has a diaphragm and through this diaphragm I bring all the smoke
by a short tube entering the lower part of the bowl tangentially near the periphery ;
a short pipe dips down from the centre of the diaphragm into this bowl, and from
this pipe I take off the smoke by a duct leading to the mouth piece. Preferably
however I prefer to put a second separator in this passage.
This consists of a
second vertical cylinder. The duct enters the vertical cylinder, that is a cylinder
with a vertical axis tangential at the top and exits by means of a pipe dipping
down into the centre from the top and being carried to the mouth piece. Both
these subsidiary bowls are provided with wells and plugs for extracting the nicotine
or saliva as the case may be. Each pipe has a continuation to the outside so that
a wire can be pushed down it if requisite, and is supplied with a plug.
I have now described my experimental apparatus. It is obvious however that
the arrangement of the bowl can be very considerably varied, the principal
essential point in the invention being the use of centrifugal force for separating the
liquid matter from the smoke, and this is done by means of the tangential opening
conveying the smoke to a circular chamber, and a central opening conveying it
again from that chamber. As with dust collectors the chamber could be on its
side, or inverted, but I prefer it made in the manner described for the purpose of
more easy collection of the liquid. It could be to one side of the bowl instead of
below it.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Tobacco Pipes.
I, WILLIAM SUTCLIFFE of 12, Dale Street, Sowerby Bridge in the County of
York, Joiner 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 has for its object a pipe that will separate the nicotine so that
the smoker can smoke the entire charge without the smoke tasting strongly.
The invention consists essentially in introducing the system of separating by
vortex similar to the well known Tornado dust collectors of P. van Gelder of which
I am the manufacturer.

page_text: It is best described by aid of the accompanying drawing, in which
Figure 1 is an elevation;
Figure 2 a vertical section;
Figure 3 a horizontal section and
Figure 4 a plan of my improved pipe.
In these A is a bowl of meerschaum or other suitable material, such as is now
used for pipe bowls; B is a metallic chamber below. It can however be formed
of other suitable material. Into this the smoke descends through orifices a a.
C is a tube having a stopper D and a dependent branch E exactly in the
centre line of circular chamber B. F is the pipe tube of any suitable material
having passage G a continuation of tube C. H is a second round chamber into
which passage G enters tangentially; I a depending tubelet similar to E and J
a tube similar to C, having also a stopper D and forming the passage leading to
the mouthpiece. L in the main bowl is a horizontal diaphragm separating the
upper part N of chamber B from its lower part O. M is a tube introducing the
smoke from chamber N into chamber O, which it enters tangentially.
The mode of operation is as follows-
The lighted charge of tobacco being placed in bowl A and smoking being
commenced in the usual manner, the smoke is drawn out of the bowl A through
gates a a into chamber N passing through passage M it enters the round
chamber tangentially. This causes a vortex. The nicotine, water and other
heavy particles are driven by centrifugal force to the side and sink to the lowest
point of chamber which can contain a porous plug and the usual means for
removal, the lighter gas, air and smoke rise up and pass through tubes E and C
to the second chamber H which they enter tangentially, this causes a second
vortex and second separation of nicotine, water, etcetera, by centrifugal force, the
remaining smoke rises up through tubes I and J to the mouthpiece or if desirable
to another centrifugal chamber before exiting. It is obvious that the bottoms of
chambers O and H can be made to take off in any way so that the nicotine can
from time to time be emptied out or the porous plug replaced, also that the pipe
can be made of several pieces simply socketted together and the chambers O and H
can be polygonal instead of round in section like Tornado dust collectors.
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. A pipe arranged with one or more approximately circular separating
chambers in which the smoke enters substantially tangentially and forms a vortex
and from which it escapes at a central point the nicotine and moisture remaining
in great part behind separated from the smoke by centrifugal force.
2. The pipe constructed and acting substantially as described.
