SIUNAL
An Improved Tobacco Pipe Cleaner.
I, AUGUSTUS LEHMANN of 42 Narcissus Road, West Hampstead, London, N.W.,
Commercial Agent, do hereby declare the nature of this invention to be as
follows:-
A tobacco pipe can be cleaned out by means of one of the pear shaped india
rubber surgical syringes from which the spout has been removed. The open end
of the syringe is placed into the bowl of the pipe, closing it hermetically; the
mouth piece of the pipe is held in a vessel containing water; by squeezing the
body of the syringe and then releasing the pressure a partial vaccuum is created
which causes a rush of water from the vessel through the stem of the pipe.
By repeated squeezings the water is forced in and out through the pipe and
cleanses it.
In order to obtain a greater vacuum I attach a cup shaped handle to the end of
the india rubber bulb and give the handle a sharp push; this doubles the bulb
inward and leaves hardly any space for air. The water, after having filled the
syringe, is forced back through the pipe in a much more powerful stream than by
simply squeezing the bulb, and the pipe gets cleaned out much quicker and more
effectually.
To improve still more upon this principle I construct the bottom of the india
rubber bulb more or less inverted towards the centre; the handle is made to fit the
inverted bottom which in use gets pushed right into the bowl of the pipe up to
the mouth of the bulb, leaving little or no space for air and thereby increasing the
power of the syringe.
Another improvement is to place, loose or fixed, an india rubber ring a little
way up round the pear shaped bulb of the syringe, so that when the syringe is used
this ring rests on the edge of the bowl of the pipe and, by pushing the handle, is
pressed tightly in contact with the pipe and the syringe. This prevents any water
forcing its way upward out of the bowl of the pipe in case the apperture of the
latter is not sufficiently round to allow of hermetic closure by the pipe cleaner.
This pipe cleaner is light and handy for carrying in the pocket, and cheaper
than metal syringes. It is to be named "The Express Pipe Cleaner."

I, AUGUSTUS LEHMANN of 42 Narcissus Road, West Hampstead, London,
Commercial 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 :-
A. tobacco pipe can be cleaned out by means of one of the pear shaped india
rubber surgical syringes from which the spout has been removed. The open end
of the syringe is placed into the bowl of the pipe closing it hermetically; the

page_text: mouth piece of the pipe is held in a vessel containing water; by squeezing the
body of the syringe and then releasing the pressure a partial vaccuum is created
which causes a rush of water from the vessel through the stem of the pipe and by
repeated squeezings the water is forced in and out through the pipe, thereby
cleansing it.
In order to obtain a greater vacuum I attach a cup shaped handle to the bottom
of the india rubber bulb and give the handle a sharp push; this doubles the bulb
inward and leaves hardly any space for air. The water after having filled the
syringe is forced back through the pipe in a much more powerful stream than by
simply squeezing the bulb and the pipe gets cleaned out much quicker and more
effectually.
To improve still more upon this principle I construct the bottom of the india
rubber bulb more or less inverted towards the centre as shown in Fig. 1 of the
accompanying drawing. The handle is made to fit the inverted bottom which in
use gets pushed right into the bowl of the pipe up to the mouth of the
syringe leaving little or no space for air and thereby increasing the force of the
syringe.
Another improvement is to place loose or fixed an india rubber ring a little way
up round the neck or shoulder of the pear shaped bulb so that when the syringe
is used this ring rests on the edge of the bowl of the pipe and by pushing the
handle is pressed tightly in contact with the pipe and the syringe. This prevents
any water forcing its way upwards out of the bowl of the pipe in case the apperture
of the latter is not sufficiently round to allow of hermetic closure by the pipe
cleaner.
This pipe cleaner is worked by one hand only, the other hand holding the
pipe; it is light and handy for carrying in the pocket, and cheaper than metal
syringes.
EXPLANATION OF DRAWINGS :
Fig. 1 shows the india rubber bulb with the inverted bottom marked in dotted
lines;
Fig. 2 shows the complete pipe cleaner with india rubber ring attached;
Fig. 3 shows the pipe cleaner in use on the pipe with the handle pushed down.
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 what I
claim is:
1. The manufacture and use of the pipe cleaner consisting of a par shaped
india rubber bulb with a handle at the bottom as herein described.
2. The same pipe cleaner, but with inverted bottom of the india rubber bulb
and a handle at the end as herein described.
3. The same pipe cleaner with or without inverted bottom and with a ring
attached round the neck or shoulder of the bulb as herein described.
