Improvements in Tobacco Pipes.
1, WILLIAM CHARLES PHILLIPS, of 8, Cunliffe Terrace, Manningham, in the
County of York, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in tobacco pipes, and its object is to cool
the smoke before it enters the mouth of the smoker, and also prevent liquid or
condensed products of combustion from passing into the mouth.
For this purpose I stop the central passage through the pipe stem at or close to
the bowl and I provide an external passage for the smoke either of metal tubing
or other suitable material. This external passage may be carried from the bottom
of the bowl right to the mouth piece and then be bent round either one or both
sides of the stem and carried back along the upper or opposite side of the stem and
is connected to the usual central passage in the stem iminediately behind that point
where the said central passage is stopped as above mentioned. By this means the
smoke is carried to and fro along a comparatively cocl passage before it enters the
stem or mouth piece. The external passage may be made in sections so that it
may be readily taken to pieces to clean the passage, and a removable cap or caps
is or are provided arranged to collect liquid matter and facilitate discharging it.
The central bore of the pipe stem is preferably enlarged and a bundle of loofah
fibres bound or compressed into a cylindrical form is introduced into this
enlargement in the bore to filter the smoke as it is drawn through.
Other suitable fibres may be employed to form the filtering plug instead of
loofah.

I, WILLIAM CHARLES PHILLIPS, of 8, Cunliffe Terrace, Manningham, in the
County of York, Commercial Traveller, 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 improvements in tobacco pipes, and its object is to cool
the smoke before it enters the mouth of the smoker, and also prevent liquid or
condensed products of cembustion from passing into the mouth.
For this purpose I stop the central passage through the pipe stem at or close to
the bowl and I provide an external passage for the smoke either of metal tubing
or other suitable material. This external passage may be carried from the bottom
of the bowl right to the mouth piece and then be bent round either one or both

page_text: sides of the stem and be carried back along the upper or opposite side of the stem
and be connected to the usual central passage in the stem immediately behind that
point where the said central passage is stopped as above mentioned. By this
means the smoke is carried to and fro along a comparatively cool passage before
it enters the stem or mouth piece. The external passage may be made in
sections so that it may be readily taken to pieces to clean the passage, and a
removable cap or caps is or are provided arranged to collect liquid matter and
facilitate discharging it.
Reference is to be had to the accompanying sheet of drawings forming a part of
this specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a side view of my improved pipe.
Figure 2, represents a longitudinal section of the same with a portion of the
month piece broken away and
Figure 3, is a cross section on the broken line a, b Figure 2.
Figure 4, represents a longitudinal section illustrating a modification and
Figure 5, is a plan view of the same.
Figure 6, represents a separate view of a removable loofah or fibrous plug
adapted to be placed in the smoke passage to filter the smoke.
Referring more particularly to Figures 1, 2 and 3 the passage A from the
bottom of the bowl A 2 opens into a chamber A 3 fitted with a removable cap A 4.
The tube B let into the underside of the stem A 5 conducts the smoke from the
chamber A3 to the annular passage C formed under the mount D between the end
of the stem and the mouth piece E. The upper side of the annular passage C is
connected by the tube F to the opposite end of the central passage G which latter
passage has no other communication with the bowl. The mouth piece E is
preferably provided with a tube H fixed into it which tube fits the passage G and
may extend almost to the opposite end of this passage.
In the construction shown in Figures 4 and 5 the tubes B and F are not let into
the stem and their ends next to the mouth piece are connected by the annular
tube C2. The tubes B and F have joints formed at 132 and F2 to enable the
tube C2 to be detached and the tubes removed when the passages require
cleaning.
The central passage in Figure 4 is enlarged to receive a removable plug K
formed of a bundle of loofs fibres covered with a suitable absorbant paper. These
plugs may also be used to filter the smoke in ordinary tobacco pipes if the smoke
passage is made large enough. Other similar fibres may be employed instead of
loofah.
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. The improvements in tobacco pipes whereby the smoke passage from the
bowl to the mouth piece is increased in length, substantially as herein described
and illustrated in the accompanying drawings.
2. An absorbant plug formed of loofah or similar fibres adapted to be placed
within an enlarged sincke passage in the stem of a tobacco pipe, substantially as
herein shown and described.
