City of Westminster Consulting and Mechanical Engineer do hereby declare the
nature of this invention to be as follows !—
These improvements have reference to pipes in which to smoke tobacco.
A want has hitherto existed of a pipe with a meerschaum bowl (generally
acknowledged to be the perfection of smoking) which can be kept cool, with a
chamber for deposit of the nicotine, with a free and easy smoke, with means of
thorough cleaning all conjoined with moderate expense

According to my invention a bowl of meerschaum is provided in which the
tobacco to be smoked is placed. This bowl is of the simplest possible construction,
all circular and turned in the lathe and it contains a minimum quantity of
meerschaum.
This bowl is inserted in a casing leaving an air chamber. round it. This air
chamber is fed with cold air through holes at the bottom of it, and the said air
after coming in contact with the meerschaum bowl (during the process of smoking)
extracts heat from it and ascends to the top of the bowl and air chamber where it
passes out through holes in the side of the air chamber casing to the atmosphere.
A current of fresh air is thus continually surrounding the bowl tending to keep
it cool.
At the bottom of the bowl there is a projecting piece which fits into an aperture
in the air chamber casing, and in this manner all communication between the air
chamber and the smoking tube is cut off. The bowl can be easily removed,
Instead of meershaum for cheapness sake, the bowl may be made of compressed
clay charcoal, or asbestos, or briar or cherrywood or any other suitable material,
but I prefer meerschaum.
The air chamber casing can be cast of vulcanite or other suitable material, thus
avoiding the present amount of skilled labour in the manufacture of. a pipe and
thereby contributing materially towards its economical production.
In the air chamber casing the smoke is conducted through a tube into a chamber
for the deposit of the nicotine, and by means of the usual mouthpiece the purified
amoke can be extracted therefrom.

I, JOHN CHARLES WILSON of 5 Westminster Chambers Victoria Street in the
City of Westminster Mechanical and Consulting Engineer 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 :-
These improvements have reference to pipes in which to smoke tobacco.
A want has hitherto existed of a pipe with a meerschaum bowl (generally
acknowledged to be the perfection of smoking) which can be kept cool; with a
chamber for deposit of the Nicotine; with a free and easy smoke; and with means
of thorough cleaning; all conjoined with moderate expense.
According to my invention, a bowl of meerschaum is provided in which the
tobacco to be smoked is placed. This bowl is of the simplest possible construction,
being all circular and turned in the lathe; and it contains a minimum quantity of
meerschaum,
This bowl is inserted in a casing leaving an air chamber around it. This air
chamber is fed with cold air through holes at the bottom of it, and the said air
after coming in contact with the meerschaum bowl (during the process of smoking)
extracts heat from it and ascends to the top of the bowl and air chamber where it
passes out through holes in the side of the air chamber casing to the atmosphere.
A current of fresh air is thus created around the bowl tending to keep it cool.
The bottom of the bowl is screwed tight against the bottom of the air chamber
casing, and in this manner all communication between the air chamber and the
smoking tube is cut off. The bowl can be easily removed. Instead of meerschaum,
for cheapness sake, the bowl may be made of compressed clay, charcoal, or asbestos,
or briar or cherry wood, or any other suitable material, but I prefer meerschaum.
The air chamber casing can be made of wood as usual, but I prefer to make
it of vulcanite, thereby avoiding the present expense of skilled labour in the
manufacture of a pipe and so contributing materially towards its economical
production.
The smoke is conducted through a tube into a chamber in the stem of the pipe
for the deposit of the nicotine and after traversing this chamber it passes into a
metal cylinder where it is still further condensed and cooled, and ultimately by
means of the usual mouthpiece the purified smoke is extracted therefrom. This
metal cylinder can be very easily removed and both it and the nicotine chamber
quite easily and thoroughly cleaned.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed,

holes by which the smoke enters the metal condensing tube. k is the condensing
tube. is the smoke passage to the mouth piece. m is the mouth piece.
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 separate bowl fitted into a casing with a ventilated air chamber around
the bowl substantially as described.
2. The nicotine chamber in the stem of the pipe arranged substantially as shown,
in combination with the ventilated bowl
3. Making the outer casing of the pipe of vulcanite so as to avoid the present
expense of skilled labour in the manufacture of a pipe.
