PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Cleaning Tobacco
Pipes.
I, WALTER SOWDEN, of Farnley Moor Top, Gildersome, near Leeds, Brassfounder,
do hereby declare the nature of this Invention to be as follows:-
I employ a small cylinder with piston and rod, the cylinder terminates in a tube
(the whole being in syringe form) upon which is a plug of indiarubber, cork, or other
suitable substance, so as to form a stopper. The plug is inserted in the mouth of the
bowl of the pipe and the stem of the pipe is dipped in the cleansing liquid, which
may be water, hot or cold, or other liquids. The piston is then operated within the
cylinder, and the liquid is repeatedly drawn in and forced out through the stem until
it is thoroughly cleansed.
The cylinder and apparatus may be made of metal or other suitable substance.
For facilitating securing the cleaner on to the pipe, a clamb or fastener is secured
from the bottom of syringe to the underside of the bowl of the pipe, adjustable so
as to fit to any size of pipe.

Fig. 1. is a general view of my invention.
Fig. 2. is a detail view of syringe or force pump.
Fig. 3. is a detail view partly in section showing syringe or force pump applied
to the mouth piece or stem of the pipe instead of to the bowl of the pipe as shown
in Fig. 1.
According to my invention I employ a small cylinder A, fitted with piston B, and
rod C, the cylinder terminates in a tube D, which has a thread upon its outside, (the
whole being in syringe form,) upon which is a plug of indiarubber, cork, or other
suitable substance E, so as to form a stopper. The plug E is inserted in the mouth of
the bowl of the pipe G and the stem H of the pipe is dipped and held in the glass
or other receptacle containing the cleansing liquid which may be water, hot or cold,
or other suitable liquids may be used. The piston is then operated within the
cylinder, and the liquid is repeatedly drawn in and forced out through the stem
until the pipe is thoroughly cleansed.
The syringe or force pump may be made of metal or other suitable substance.
For facilitating securing (preferably by hand as illustrated in Fig. 1), the cleaner to
the pipe, finger holders J, project from the base of the syringe or force pump.
Or a pivotted clamp or fastener may be used to secure the cleaner to the pipe.

page_text: In lieu of the syringe or force pump being applied to the head of the pipe as shown
in Fig. 1, it may be applied to the mouth piece or stem H of the pipe, see Fig. 3.
In this case the plug E is made with a taper hole E' and screws, or is fitted on to the
screw or thread of the tube D.
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 method of cleaning tobacco pipes consisting in forcing the cleansing liquid
or liquids, backwards and forwards through the said pipes, such as shown and
described.
2. For cleaning tobacco pipes the employment of a cylinder A fitted with piston B
and actuating rod C, in combination with the elastic stopper E (or their equivalents)
such as shown and described.
