PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipe Cleaners.
I, JOHN CRAIG Junior, of 8 Wood Street, Cheapside, in the City of London,
India Rubber Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to tobacco pipe cleaners of the kind in which air can be
forced through the pipe by the breath of the user or otherwise.
According to my invention I provide a cap or plug composed of any suitable
material and having an india-rubber or other tube or mouth piece attached thereto
and in some instances furnished with an india-rubber or other flexible ball for
forcing air through the contrivance.
When employing a cap it may consist of a circular flat top of india-rubber
having a cylindrical portion also of india-rubber which is capable of rolling up to
lie snugly around the edge of the circular flat top of the cap, when the pipe cleaner
is out of use. The aforesaid cylindrical nortion is adapted to fit with sufficient
tightness around the exterior of the bowl of the pipe to form an air-tight con
nection so that when air is blown through the tube or mouthpiece it will only be
able to escane through the stem of the pipe.
The aforesaid flat top of the cap may be provided on its inner surface with a
metal or other shield to protect the india-rubber. Ür powdered asbestos may be
applied to the said top.
If desired the inner surface of the flat circular top of the cap may be of convex
or slightly conical formation to fit against the mouth of the pipe-bowl. In some
cases the aforesaid conical or convex top may be composed of metal or other hard.
substance with its inner surface lined with india-rubber and in this case the said
rolled up cylindrical portion of the cap may be dispensed with.
When employing a plug to enter the bowl of the pipe the mouthpiece may either
consist of a flexible tube as already stated, or may consist of a conical pieco
ferming part of the sides of the plug.
If the cap or plug be formed of metal or other hard substance it may be provided
with an india-rubber or other resilient ring or band so arranged that a tight joint
will be produced between the cap or plug and the bowl of the pipe.
The tube with which the cap or plug is provided may be furnished with a

page_text: vulcanite or other suitable mouth piece; or the. free extremity of the said tube
may be rolled or turned over upon itself to increase the thickness of the tube at
this part.

Improvements in Tobacco Pipe Cleaners.
I, JOHN CRAIG, Junior, of 8' Wood Street, Cheapside, in the City of London,
India Rubber 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:-
This invention relates to tobacco pipe cleaners of the kind in which air can be
forced through the pipe by the breath of the user.
According to my invention I provide a cap consisting of a circular flat top of
india-rubber having a cylindrical portion also of india-rubber which is capable of
rolling up to lie snugly around the edge of the circular flat top of the cap, when
the pipe cleaner is out of use. The aforesaid cylindrical portion is adapted to
fit with sufficient tightness around the exterior of the bowl of the pipe, to form an
air-tight connection so that when air is blown through the tube or mouthpiece it
will only be able to escape through the stem of the pipe.
The aforesaid flat top of the cap may be provided on its inner surface with a
metal or other shield to protect the india-rubber. Or powdered asbestos may be
applied to the inner side of the said top.
In order that my said invention may be clearly understood and readily carried
into effect I will proceed to describe the same more fully with reference to the
accompanying drawings in which :-
Figures 1 and 2 show sections of the improved tobacco pipe cleaner, the former
figure representing the pipe cleaner open and the latter figure (Figure 2)
representing it closed.
Figure 3 is a side elevation of a pipe with the pipe cleaner applied thereto
ready for use.
A is the cap of the pipe cleaner and B the tube or mouth piece attached thereto.
These parts are preferably formed in one piece and wholly of india-rubber. The
aforesaid cap consists of a circular flat top a, which in the case illustrated is
slightly convex on its under side, and of a flexible portion a' terminating at its
lower edge in an enlarged or beaded rim a. The portion a' is capable of being
folded upon itself as represented in Figure 2 so that the rim a occupies a position
close around the edge of the flat top a, when the pipe cleaner is out of use. When
position represented in Figure 2 to the bowl of the pipe, so that its convex
the cleaner is to be used for cleansing a tobacco pipe it is applied while in the
top a lies upon the mouth thereof and then the rolled up edge of the cleaner is
caused to unroll around the pipe bowl by a downward pressure exerted on said
edge by the user's fingers. The cleaner is thus caused to unfold and embrace
the upper part of the pipe bowl, the rim a firmly clasping the said bowl so as to
produce an air-tight joint. The said cleaner is used while the pipe is properly
alight. Then by placing the mouthpiece B in the mouth and blowing through
it, the hot smoke is caused to pass forcibly through the stem and mouthpiece of

page_text: the pipe, thereby carrying with it and ejecting the nicotine and other deleterious
deposits that may have accumulated in the pipe.
If desired the mouthpiece B may be made of vulcanite or other appropriate
material and be connected to the cap A in any suitable manner.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
1 claim is:
A tobacco pipe cleaner consisting in the combination of a mouthpiece and a
flexible cap adapted to be rolled up when out of use substantially as described.
