Improvements in Tobacco Pipes.
-
I, HENRY FREEMAN of 1 Rappart Road, Seacombe in the County, of
Chester, Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to tobacco pipes and consists in interposing between the
bowl and mouthpiece or stem a smoke box or: chamber specially constructed to
afford a rapid cooling of the smoke and condensation of the nicotine.
I provide this smoke box or chamber which may be of any suitable form or
construction, with a series of hollow partitions extending within the box, having
their inner ends closed, and their outer ends open to the atmosphere.. These
partitions may be formed separately and inserted in the box, or may be produced
by making the sides of the box of a corrugated or zigzag shape. By this means
I produce a series of pockets on the exterior of the box or chamber which being
open to the air provide a large; cooling surface for the smoke which passes round
them..
•
In carrying out my, invention, I prefer to make the sides of this smoke box or
chamber in one piece of suitable light material preferably a thin sheet of aluminium
cut or stamped out, to the required size and shape. I provide this. sheet with an
edging of brass or similar metal by bending a strip of such metal over the edges of
the sheet to facilitate the soldering together of the ends of the smoke. box or
chamber. This sheet is then bent to any depth or angle or curved as many
times as desired according to the number of hollow partitions. or air pockets
required, the two ends on meeting, being soldered firmly together. The object
in having a number of hollow partitions or air pockets being as.before stated to
produce a large cooling surface space whereby the smoke. is rendened cool and the
nicotine becomes condensed and collects in the bottom of the said smoke box or
chamber. The side ends of the air pockets produced by bending in the above
manner are separately closed by inserting thin strips of brass or other suitable
metal and then soldering. A small projection is left on the top of these small
brass strips to enable the smoke box or chamber to be firmly provided with end
pieces adapted to receive the bowl and stem or mouthpiece respectively, which may
be screwed or otherwise fixed thereto. These end pieces are also made of brass.or
other suitable metal bent at each of their sides to overlap the sides of the box to
facilitate soldering. A screw plug is preferably fixed to one end piece of the
smoke box projecting therein on the outer end of which plug the pipe bowl may be
screwed. Below this a small E or other shaped piece of brass is also soldered, the
prongs of which 'fit into the spaces between the partitions or air pockets of the
smoke box or chamber thereby preventing the flow of nicotine from the smoke box
to the bowl when the pipe is inverted to eject spent tobacco. At the bottom of this
end piece I pierce a hole or aperture through which the nicotine can be emptied
when required. This hole or aperture may be covered by means of a cap or any
other suitable means..

improvements in Tacco ripes.
I, HENRY FREEMAN of 1 Rappart Road, Seacombe in the County of
Chester, Agent, 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 tobacco pipes and consists in interposing between the
bowl and mouthpiece or stem a smoke box or chamber specially constructed to
afford a rapid cooling of the smoke and condensation of the nicotine
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which,
Figure 1 is a longitudinal section of my pipe on line xy, Figure 3;
Figure 2, a fragmentary view partly in section; and
Figure 3, a plan.
In these,
A is the tobacco bowl, B the mouthpiece, C the smoke box or chamber. This
smoke box or chamber may be of any suitable form or shape and provided with
one or more hollow partitions D extending through the box from side to side
through which atmospheric air can pass. By this means I produce a series of
hollow passages or pockets through the smoke box or chamber which being open
to the air at each end, provide a large cooling surface for the smoke which passes
around them. E is a screw plug fixed near one end of the smoke-box and projecting
therein, and on the outer end of which plug the pipe bowl A is screwed. This
plug projects at one end beyond the inside of the smoke box so as to prevent the
flow of nicotine from the smoke-box to the bowl when the pipe is inverted to eject
spent ash. F is a hole or aperture pierced in the bottom of the smoke-box through
which the nicotine can be emptied when required. This hole or aperture may be
covered by means of a screw cap or by any other suitable means. The mouthpiece
-
is preferably detachable being screwed or socketted into the smoke box in any
suitable manner.
The mode of action is as follows:-
In smoking the pipe, the smoke is drawn through the tube E into the smoke
box C, and in course of its passage through the box comes in contact with the
tapering hollow partitions or air pockets D which being exposed to a current of
cool air, produce a large cooling surface whereby the smoke is rendered cool and
the nicotine becomes condensed and collects in the bottom of the box C, the
cooled smoke being drawn through the passages c and through the mouthpiece B
into the mouth.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I wish it to be
understood that I do not confine myself to the exact arrangement shown and
described, as the same may be altered without departing from the nature of my
invention, thus by way of example any suitable number of hollow partitions may
be employed and moreover other suitable means may be used for coupling the
bowl to the smokepiece, but 1 declare that what I claim is:—
1. The improvement in tobacco pipes, which consists in interposing between the
bowl and mouthpiece or stem a smoke box or chamber specially constructed to
afford a rapid cooling of the smoke and condensation of the nicotine, substantially
as described.
2. A tobacco pipe, in which that portion between the mouthpiece and bowl is
formed of a smoke-box having one or more hollow partitions or air passages

page_text: extending within the box, whereby a large cooling surface is provided for the
smoke which passes around them substantially as described.
3. The improved tobacco pipe as a whole substantially as set forth.
