Complete Specification Left, 28th Mar., 1898-Accepted, 18th June, 1898
I, JOSEPH COILN, Merchant, of 366, City Road, London, E.C., in the County of
London; do hereby declare the nature of this invention to be as follows:-
Subject of the present invention is an arrangement by means of which tobacco
pipes can be easily and neathly cleaned in a thorough manner without having to take
them to pieces and so as to remove every impurity from them.
This contrivance for cleaning smoking pipes consists of a fire-proof glass tube of
about the thickness of a finger and about four inches long, which is perfectly closed
at one end, whilst to its other end an india rubber tube is put on which ends into a
tapering point provided with an orifice.
After the glass tube has been half filled with any kind of alcoholic spirit, the
rubber tube is slipped on and in its free end the mouthpiece of the pipe to be cleaned
is introduced.
After having lit a candle or gas flame the pipe as well as the fireproof glass tube
containing the spirit are brought with both hands into a horizontal position and the
glass tube is held so long in the flame until the spirit begins to boil and that will
occur in a few seconds. The consequence is that the spirit now expands with great
force, penetrates into the pipe until the bowl and dissolves and carries off every
particle of impure matter. The heating is continued until the spirit in the glass
tube has become quite dirty, whereupon it is poured off. If a second operation is
desirable the process is simply repeated, but as a rule a single cleaning is sufficient
to obtain a perfectly sweet pipe.
In using this method of cleaning smoking pipes there is no dirtying of hands
and clothes involved.

I, JOSEPH COHN, Merchant, of 366, City Road, in the County of London, 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 chiest of this invention is an arrangement by means of which tobacco pipes

to pieces and so as to remove every impurity from them.
In the accompanying drawing

Fig. 1 shows a side view of the pipe cleaner fixed on the tobacco pipe.
This contrivance for cleaning tobacco pipes consists of a fire proof glass tube a of
about the thickness of a finger and about four inches long which is perfectly closed
at one end, whilst over the other, an india rubber tube is slipped on, which ends
into a tapering point.

First the glass tube a is to be half-filled with any kind of alcoholic spirit, then
the mouthpiece of the pipe to be cleaned is pushed into the tapering orifice of the
india rubber tube b and is tlius connected with the glass tube!
After having lit a candle or a gas flame the glass tube b containing the spirit is
brought into a horizontal position and is held so long in tlie flame until the spirit
begins to boil and that will occur in a few seconds. The consequence is that the
spirit now expands with great force, penetrates into the pipe as far as the bowl,
dissolves and carries back into the glass tube every particle of impure matter, there-
fore the heating is to be continued until the spirit in the glass: tube has become
quite dirty, wliere-upon it is poured off. If a second operation' is desirable tho
process is simply repeated, but as a rule a single cleaning is sufficient to obtain a
perfectly sweet pipe.

In using this method of cleaning tobacco pipes there is no dirtying the hands
and clothes involved.
+!
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:-
+
I
1) Pipe cleaner consisting of a fire proof glass tube a, which is perfectly closed
at one end whilst over the other an india rubber tube 6 is slipped substantially, as
described and represented in the accompanying drawings.
-
2) The connecting of the pipe with the glass tube through the medium of the
india rubber tube after the glass tube has been filled for use half way up with spirit
which must be heated to a chief desired effect.
