A NEW OR IMPROVED TOBACCO PIPE CLEANER
Year: 1885

page_text: I JOHN LORD HINDE of N° 103 Suffolk Street Birmingham in the County
of Warwick Brush Manufacturer and Merchant do hereby declare the nature of
the said Invention for "A NEW OR IMPROVED TOBACCO PIPE CLEANER " to be as
follows:
My invention consists of a tobacco pipe cleaner made as herein after described
whereby the bowl and stem of the tobacco pipe are cleaned in a simple and efficient
manner of the oil of tobacco contained in thein and other foul matter adhering to
them.
In making my new or improved tobacco pipe cleaner I take a disc or pad of
leather millboard papier mâché or other light material and I attach to the middle
of the disc or pad a deflagrating composition such as meal gunpowder or a mixture
of nitre and charcoal the said composition being moulded into à dome shape or
such other shape as will readily enter the bowl of the tobacco pipe. The summit
of the deflagrating composition is tipped with an igniting mixture of the kind
used for tipping ordinary pipe lights and matches so that by friction the detta-
grating composition may be ignited. The whole of the face of the disc or pad on
which the deflagrating composition is attached or the marginal part only of the
face of the disc or pad is covered with felt thin india rubber or other yielding
material so that when the disc or pad is pressed upon the top of the bowl of the
pipe so as to close it an air tight joint is formed between the edge of the bowl and
the marginal part of the disc or pad.
In using my improved tobacco pipe cleaner the deflagrating composition at the
middle of the disc or pad is ignited by friction after the manner of igniting au
ordinary pipe light and the disc or pad is then pressed upon the top of the pipe
bowl the ignited deflagrating composition entering the said bowl.
As the disc or pad forms a temporary air tight cover to the bowl of the pipe the
gases emitted in the bowl from the deflagrating composition can only escape
through the stem of the pipe in doing which they force before them the oil of
tobacco and other foul matter contained in or adhering to the bowl and stem and
thereby very efficiently clean the pipe.

page_text: I JOHN LORD HINDE of N° 103 Suffolk Street, Birmingham in the County of
Warwick, Brush Manufacturer and Merchant, 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 :-
My invention consists of a tobacco pipe cleaner made as hereinafter described,
whereby the bowl and stem of the tobacco pipe are cleaned in a simple and
efficient manner of the oil of tobacco contained in them and other foul matter
adhercing to them.
"
In making my new or improved tobacco pipe cleaner I take a disc or pad of
leather, millboard, papier mâché or other light material and I attach to the middle
of the disc or pad a deflagrating composition such as meal gun powder or a mixture
of nitre and charcoal, the said composition being moulded into a dome or spherical
shape or such other shape as will readily enter the bowl of the tobacco pipe.
The summit of the deflagrating composition is tipped with an igniting mixture
of the kind used for tipping ordinary pipe lights and matches so that by friction
the deflagrating composition may be ignited. The whole of the face of the disc or
pad on which the deflagrating composition is attached or the marginal part only of
the face of the disc or pad may be covered with felt, thin india rubber or other
yielding material so that when the disc or pad is pressed upon the top of the bowl
of the pipe, so as to close it, an air tight joint is formed between the edge of the
bowl and the marginal part of the disc or pad. The pipe cleaner is used in the
manner hereinafter described.
Figure 1 of the accompanying Drawing represents in side elevation and plan of
underside, a tobacco pipe cleaner, drawn double the full size, made according to my
invention and Figure 2 represents the manner in which it is applied to the bowl
of a tobacco pipe for cleaning the said pipe.
a is the disc or pad which when in use forms a temporary air tight cover to the
bowl of the pipe. The said disc or pad is made preferably of millboard or papier
mâché but it may be made of leather or other light material. On the underside of
the middle of the disc or pad a the pear (or other) shaped deflagrating com-
position b is fixed by its stem, the said composition 6 being tipped at c with a
frictional igniting composition of the kind used for tipping ordinary pipe lights.
The face of the disc or pad a to which the deflagrating composition 6 is fixed may
be wholly or in part covered with felt or other yielding material to form an air
tight joint or packing between the top of the pipe bowl and the said disc or pad
but in practice I have found that a sufficiently air tight joint between the disc or
pad and the mouth of the bowl is formed without the use of felt or other yielding
material.
In using my improved pipe cleaner the deflagrating composition 6 at the middle
of the disc or pad a is ignited by friction of the part c after the manner of igniting
an ordinary pipe light and the disc or pad is then pressed upon the top of the pipe
bowl, the ignited deflagrating composition b entering the said bowl in the manner
represented in Figure 2. As the disc or pad a forms a temporary air tight cover

page_text: o the bowl of the pipe the gases emitted in the bowl by the ignited deflagrating
composition can only escape through the stem of the pipe in doing which they force
before them the oil of tobacco and other foul matter contained in or adhering to
he bowl and stem and thereby very efficiently clean the pipe. Figure 3 represents
n section and plan of underside a modification of the pipe cleaner already described
and Figure 4 represents the same applied to a pipe.
In this modification the deflagrating composition instead of being made in one
piece is divided into four (or more) portions d, d, d, d' each portion being tipped
with a frictional igniting composition. The central portion d² of the deflagrating
composition projects beyond the others and is ignited before the pipe cleaner is
placed upon the top of the bowl in the manner represented in Figure 4. The
central projecting portion d2 of the deflagrating composition when in the bowl
ignites the other portions d, d the emitted gases acting as herein before described.
A tubular case e may be combined with the disc or pad a as represented in
Figures 3 and 4 for passing over the exterior of the bowl in using the pipe cleaner.
Pipe cleaners made according to my invention may be employed in cleaning
pipes having bowls of the various ordinary sizes, the disc or pad a fitting the top
of the bowl whether the bowl be of the relative size represented in the Drawing or
of double the size or of any intermediate size.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that what
I claim is
o
A new or improved tobacco pipe cleaner consisting of a disc or påd either alone
or in combination with a tubular case, the underside of the central part of the
said disc or pad being provided with a deflagrating composition tipped with a
frictional igniting mixture, the said disc or pad forming a temporary air tight cover
to the pipe bowl and preventing the escape of the gases emitted by the ignited
deflagrating composition substantially as herein before described and illustrated in
the accompanying Drawing.
