A DEVICE TO BE USED IN CLEANING THE INTERIOR OF TOBACCO PIPES
Year: 1884

page_text: COMPLETE SPECIFICATION.
I, SIDNEY GRAFTON, of 54,, William Edward Street, Birmingham, in the County
of Warwick, Engineer, do hereby declare the nature of the said invention for
"A DEVICE TO BE USED IN CLEANING THE INTERIOR OF TOBACCO PIPES," and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my Invention is to furnish an inexpensive and convenient device
to be used for cleaning the interior of tobacco pipes and my Invention consists in
a plug or stopper adapted to fit in the bowl of the pipe and provided with a cavity
or recess to receive and hold either a charge of combustible material, the ignition
of which generates gases which serve to drive out through the mouth piece the
nicotine that is deposited in the pipe after frequent smoking, or to hold a match
for igniting a charge placed in the bowl of the pipe.
The plug may be of any suitable material but it is preferably made of wood,
metal or other hard substance and partly covered with indiarubber or equivalent
material.
The upper part of the plug is of cylindrical form and its lower part is made
taper or conical so as to enable the device to be forced into and securely held in
the pipe when in use.
In order that the Invention may be better understood I have illustrated the
same in the accompanying drawings, wherein figure 1 shews an elevation, and
figure 2a plan, and figure 3 a section of the device. In figure 4 the device is
shewn attached to a pipe as in the act of cleaning while figure 5 shews a modified
form of plug.
a is the body of the plug which is bored out centrally so as to form the cavity a¹
to hold the charge of combustible material b. This charge may be made of the
materials ordinarily used for the manufacture of vesuvian matches and tipped with
phosphorus or a charge consisting of such materials may be placed in the bowl of
the pipe and be ignited by a match or vesuvian which is held by the plug. In
either case the operation would be the same. The upper part of the plug may be
made of cylindrical or of other form but its lower portion is made cylindro-conical
and surrounded with a packing or collar of indiarubber or other suitable material d
to cause the plug to be retained firmly in the pipe when forced in. That portion

page_text: of the plug surrounded by the packing is of less diameter than the upper portion
so as to form a ledge at against which the packing ring, abuts and by which it is.
prevented from being displaced when the plug is forced in the pipė.
In using the device the charge having been placed in the cavity of the plug is
ignited and the plug inserted in the bowl as in figure 4, whereupon the gases
generated and confined in tho bowl pass out through the mouth pieco and drive tho
accumulated deposit before them.
In using the device shewn in figure 5 which is adapted to hold an ordinary
match or vesuvian the charge of coinbustible material is placed in the bowl and on
igniting the match and inserting the plug in the bowl the charge is ignited and
the deposit forced out as above described.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I clnim is:
1 A device for use in cleaning out the interior of tobacco pipes consisting of a
plug or stopper adapted to fit the bowl of the pipe and provided with a cavity or
hole to retain ignitible material substantially as shown and described.
2nd. A device for use in cleaning out the interior of tobacco pipes consisting of
the taper plug a having a hole or recess for the reception of the ignitible material
and provided with a packing or collar of indiarubber or equivalent material
substantially as shown and described.
Dated thie 22nd day of September 1884.
