PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes.
I, AUSTIN CLARKSON, of Cemetery Lodge, Preston, Clerk, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in tobacco pipes, and has for its object a
series of chambers arranged in the air passage of a pipe, in such a manner that the
smoke will come in contact with the walls of such chambers and will deposit
whatever nicotine or moisture it may contain, in the said chambers. In carrying my
invention into practice I form such tobacco pipe in three pieces, one of which forms
the bowl made with the ordinary small air-passage leading into the stem, which is
hollowed out so as to form a chamber. One end of a smaller cylinder, divided
lengthwise in the centre, forming two chambers, one of which is closed in at one
end, and the other closed in at the reverse end, fits into the said chamber, until the
other end of the said cylinder or tube, fits into the mouth-piece end of the stem.
The mouth-piece end of the stem is formed with a hollow chamber through which a
small air-tube or passage passes at the top, communicating with the mouth-piece, so
that when the mouth-piece end is fitted over the afore-mentioned cylinder, the small
air-tube is inserted in the top closed chamber.
When the smoke is drawn through the air-passage, it has to ascend to the top
air chamber, and travel back till it is drawn through the small air-tube, and so into
the mouth.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, AUSTIN CLARKSON, of Cemetery Lodge, Preston, in the County of Lancaster,
Clerk, 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 to cool the smoke as it passes from the bowl of
a tobacco pipe to the mouth of the smoker which object I effect in the following
manner: Inside the stem of the pipe between the mouthpiece and the bowl I
insert a thin sheet metal cylinder divided into an upper and a lower compartment by
a partition running horizontally from end to end of the cylinder. That end of the
upper compartment which is nearest to the bowl is stopped up or closed the lower
compartment being left open but being in communication with the upper compart-
ment at the end nearest the mouthpiece through a suitable opening. A small tube
projecting from the inner end of and communicating with the central orifice of the
mouthpiece occupies a position centrally and laterally within the upper compartment
and is of such a length as to be capable of receiving the smoke which having passed
along the lower open compartment passes into the upper compartment and along it
in the reverse direction and is then drawn into and through the said small tube and
into the central orifice of the mouthpiece.

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 :-
In a tobacco pipe the insertion in the stem thereof of a cylinder divided
horizontally so as to form an upper and a lower compartment that end of the
upper compartment nearest the bowl of the pipe being closed and a small tube
fixed to the mouthpiece occupying a position within the said upper compartment
the said parts being arranged substantially as hereinabove described and shewn in
the drawings for the purpose set forth.
