Improvements in Tobacco Pipes.
I ABRAHAM KAHN, Traveller, of Louisenstrasse 15, Frankfurt af Main, in the
Empire of Germany, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to keep the smoke perfectly dry, clean,*
aromatic, free from oil, cool and to ensure a free draught without liability to
stoppage, and consists essentially in providing the stem of the pipe with a
removable collecting tube adapted to be slid into place and having an inclined inlet
pipe adapted to connect the lower part of the pipe bowl with the collecting tube
and in providing the mouth piece with a draught tube adapted to screw into the
collecting tube and with an outlet tube projecting into the collecting tube and
fitting in the end of the draught tube and surrounding a central nozzle of the
draught tube. The collecting tube serves to collect nicotine, condensed moisture
and the like whilst the outlet tube ensures a complete condensation of the
moisture.

ABRAHAM KAHN, Traveller, of Louisenstrasse 15, Frankfurt a/ Main, in the
Empire of Germany, 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 keep the smoke perfectly dry, clean,
aromatic free from oil cool and to ensure a free draught without liability to
stoppage and consists essentially in providing the stem of the pipe with a removable
collecting tube adapted to be slid into place and having an inclined. inlet pipe
adapted to connect the lower part of the pipe bowl with the collecting tube and
in providing the mouth piece with a draught tube adapted to screw into the
collecting tube and with an outlet tube projecting into the collecting tube and
fitting in the end of the draught tube and surrounding a central nozzle of the
draught tube. The collecting tube serves to collect nicotine condensed moisture
and the like whilst the outlet tube ensures a complete condensation of the moisture.
In the accompanying sheet of illustrative drawings
-
Fig. 1 is a central vertical section of a pipe constructed according to this
invention whilst
Figs. 2-5 give detailed views of separate parts of the fittings.
The stem a of the pipe is bored out to receive the collecting tube d having a
The outer end of the
projection & sliding in a corresponding groove in the stem a.
collecting tube is reduced in diameter so as to leave an annular space between it

page_text: and the bore of the stem. A plug carrying an inlet tube c is screwed into the
inner end of the collecting tube and also has a projection k adapted to slide in the
groove of the stem a. The inlet tube c projects into the bottom of the pipe bowl
from which it slants downwards into the collecting tube d. The mouth piece b of
the pipe is fitted with a draught tube provided with an enlarged end i screwing
into the outer end of the collecting tube d and surrounding a central nozzle 1. The
outlet tube e has an enlarged end fitting into the enlarged end i of the tube f and
projecting into the collecting tube d. A fixing tube m is screwed into the mouth
piece band surrounds the draught tube f and is adapted to fit on the reduced end
of the collecting tube and within the bore of the stem.
The collecting tube serves to receive the oil nicotine pyridine and the other
detremental organic alkaloids contained in the tobacco and the outlet tube e keeps
back any moisture which drains into the tube d. The whole of these parts are
made of highly polished. or nickel plated metal partly for cleanliness and easy
emptying and cleaning and partly to increase the durability.
All the tubes forming the complete pipe are placed parallel to each other with
one exception that of the inlet tube c which in order to facilitate the flow of the
condensed nicotine moisture is inclined towards the axis of the collecting tube d.
The action of the pipe is briefly as follows:-The smoke issuing from the lower
oart of the pipe bowl is led by the inlet pipe e into the collecting tube d and as the
collecting tube is considerably wider than the tube c the smoke on entering expands
considerably and a decrease of temperature results. The condensation of the
smoke produced by the reduced temperature effects the deposit of the easily
liquified alkaloids such as nicotine and the morphine contained in the accompanying
opium contained in the tobacco smoke which are collected in the tube d and remain
there until it is cleansed without being able to reach the mouth of the smoker.
The moisture always contained in tobacco and not entirely condensed in the
tube d is on entering the still cooler tube e completely deposited and falls back in
its liquid condition into the tube d. The moisture from the mouth of the smoker is
also condensed in the tube e and led into the collector.
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 1
laim is :-
1. A tobacco pipe having a stem with an enlarged bore fitted with a removable
collecting tube adapted to be slid into place and having an inclined inlet pipe
adapted to connect the lower part of the pipe bowl with the collecting tube and
having the mouth piece fitted with a draught tube adapted to screw into the
collecting tube and with an outlet tube projecting into the collecting tube and
fitting in the end of the draught tube and surrounding a central nozzle of the
draught tube substantially as described.
2. The improvements in tobacco pipes substantially as described.
