PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes.
I, ALBERT PFLUEGER of 5 Brewer Street, Golden Square, London, Manu-
facturer of Fancy Goods do hereby declare the nature of this invention to be as
follows:-
This invention relates to tobacco pipes and has for its purpose to provide a pipe,
in which nicotine and impurities from the tobacco are absorbed so as to be prevented
from reaching the mouth of the smoker, while at the same time a novel mouth piece
is used, for the purpose of dividing the smoke prior to its discharge from the mouth
piece, thereby mitigating the acrid effect of the smoke on the tongue of the smoker.
To accomplish these purposes, the stem of the pipe is divided into three portions,
one short portion being attached to the bowl, an intermediary piece and the mouth
picce. These portions are screwed or otherwise suitably secured together so as to
be easily detachable. The stem has in its whole length a wide bore of uniform
cross-section adapted to receive a cylindric tube of absorbing material. This tube
when introduced fills up the whole bore to the extreme end of the mouth piece and
has a narrow concentric boring communicating with a corresponding aperture in the
bowl. The said tube material serves to deliver to smoke, on its passage to the
mouth piece, of any impurities and to completely absorb any nicotine or tobacco
juice that might enter the stem.
To prevent the absorbing tube from being obstructed or choked a slight spiral
spring is placed into its boring which serves for cleaning the latter. The absorbing
tube, when used up, that is to say when rendered incapable of having the required
suctory effect can be easily replaced by a fresh one; also the spiral spring is easily
replaced.
The mouth piece is, in the main, shaped as usual, that is to say so as to give hold
for the teeth; but in order to lessen the pungency of the smoke, a suitable number
of lateral perforations grouped around the fore end, serve as a substitute for the
main aperture at the extreme end hitherto used.

Improvements in Tobacco Pipes.
I, ALBERT PFLUEGER, of 5 Brewer Street, Golden Square, London W.,
Manufacturer, 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:-
The object of this invention is a tobacco pipe so disposed that nicotine or
impurities from the tobacco are absorbed within the pipe and can be easily removed.
Referring to the drawing hereunto annexed
Fig 1 is a longitudinal section of the improved pipe,
Figs. 2, 3 and 4 represent details,
Fig. 5 shows the improvement as applied to a cigar holder.
The improved pipe consists of two main parts, the mouth piece E and the bowl
portion D which is provided with female screw thread, corresponding to a male
thread of the mouth piece.
The stem of the pipe has in the middle a widened bore bb while the narrower
bores a and c are of the same width.

page_text: In Fig. 5 the cigar holder burner D¹ is merely substituted for the bowl piece D
Fig. 1 and forms with part E likewise, as above, two narrow bores a and having
equal width and between these two a wider bore bb.
The wide bore of the pipe or cigar holder serves for receiving a nicotine cartridge
or tube P made of such material as to instantaneously absorb any moisture passing
into the stem and prevent the nicotine or other impurities from arriving in the
mouth of the smoker.
The nicotine absorbing tube P is to be so determined in length and width that
during smoking the whole contents of nicotine and all moisture can be easily
absorbed by the tube.
The tube or cartridge consists of loosely rolled-up absorptive paper, which must
be formed upon a core or pin in order to form a channel for the passage of the
smoke from the tobacco into the mouth piece.
Instead of absorptive paper also any other convenient material capable of readily
absorbing moisture may be employed, provided such material can be rolled and does
not stick together, as otherwise the intended effect would not be produced. The
absorptive material must moreover have sufficient stiffness to ensure the tube
formed by rolling over a core remaining uninjured during use.
To accomplish the purpose intended by the application of the absorptive tube,
the latter must be at least 7 centimetres in length and 7 millimetres in width. The
channel or smoke passager has as diameter the radius of the cartridge, while the
bores a and c have as diameter the radius of passage r.
The last winding of the cartridges must not be stuck fast and to keep the
cartridges, a quantity of which is kept in store, uninjured, a thin piece of silk paper B
is laid around the cartridge and stuck fast with the weakly gummed outer edge.
A pipe or cigar holder provided with the described nicotine tube or cartridge
remains constantly dry and does not emit any smell, while the tobacco can be smoked
up to the last without the least unpleasant taste or smell to the smoker.
The extraordinary cheapness of the cartridge allows of its being renewed daily
or as frequently as required or desired and by its use the cleaning of pipes or cigar
holders is rendered superfluous.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
In tobacco pipes and cigar holders with detachable tubes or stems, the application
of a cartridge or tube P for absorbing nicotine or moisture, which is centrally lodged
in the widened bore bb and consists of a roll of absorptive paper or of any other
absorptive material in the shape of a roll, said roll being held compact by band o
covering of silk paper and having a longitudinal central smoke passager which i
equal in diameter to the radius of the cartridge and equal in radius to the diamete
of the bores a and c, substantially as and for the purpose set forth.
