Improvements connected with Cleaning the Bowls of Tobacco Pipes,
and Appliances therefor.
I, ALFRED JOHN HAUGHTON, of 17 Brunswick Street, Liverpool, in the County of
Lancaster, Corn Broker, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object to provide a ready and efficient means to remove
the carbonaceous cake which forms on the inside of the bowls of tobacco pipes.
The inside of the bowls of tobacco pipes, as is well known, after use become
clogged or choked with a carbonaceous cake, which not only reduces the tobacco
holding capacity of the pipe, but causes the pipe to become foul. The usual way of
removing this carbonaceous cake is by cutting it away with a penknife, but this
often damages the bowl of the pipe, and does not evenly remove the cake.
According to my invention I provide a tool, in the form of a metal rimer, with two
or more cutting edges and a rounded end or nose. This rimer is of such a size as
to fit the usual size or sizes of tobacco pipes, for example about 3 of an inch outside
its cutting edges, the said cutting edges oxtending slightly under the end of the tool,
and the tool being provided with a suitable handle. The tool may be made of cust
steel or iron, or other suitable metal cast in one piece, or it may be of metal such as
light steel bar, and constructed in the form of a cage, the edges of the bars forming
the cutting edges of the tool. The cage may be made provided with a central screwed
spindle or its equivalent, by which the cage may be expanded, or reduced in size, so
that it will serve for different sized bowls.
By my invention the carbonaceous cake which forms inside the bowls of tobacco
pipes can be readily removed by inserting the rimer into the bowl and turning it
round, the cutting edges of the rimer evenly removing the cake and without damaging
the bowl of the pipe.

Improvements connected with Cleaning the Bowls of Tobacco Pipes,
and Appliances therefor. .
I, ALFRED JOHN HAUGHTON, of 17, Brunswick Street, Liverpool, in the County
of Lancaster, Corn Broker, do hereby declare the nature of my said Invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following stateinent :-
My Invention has for its object to provide a ready and efficient means to remove
the carbonaceous cake which forms on the inside of tobacco pipes.
The inside of the bowls of tobacco pipes, as is well known, after use become clogged
and choked with a carbonaceous cake, which not only reduces the tobacco holding
capacity of the pipe, but causes the pipe to become foul. The usual way of removing
this carbonaceous cake is hy cutting it away with a penknife, but this often damages
the bowl of the pipe, and does not evenly remove the cake.
According to my Invention, I provide a tool, in the form of a metal rimer, with
two or more cutting edges and a rounded end or nose. This rimer is of such a size
as to fit the usual size or sizes of tobacco pipes, for example, about 7 of an inch
outside its cutting edges, the said cutting edges extending slightly under the end of

page_text: the tool, and the tool being provided with a suitable handle. The tool may be made
of cast steel or iron. or other suitable metal, cast in one piece, or it may be of metal
such as light steel bar and constructed in the form of a cage, the edges of the bars
forming the cutting edges of the tool. The cage may be male provided with a
central screwed spindle or its equivalent, by which the cage may be expanded, or 5
reduced in size, so that it will serve for different sized bowls
By ny Invention the carbonaceous_cake which forms_inside_the bowls of tobacco
pipes, can be readily removed by inserting the rimer into the bowl and turning it
round the cutting edges of the rumer evenly removing the cake and without
damaging the bowl of the pipe
In the foregoing description I have set forth generally the nature, object and effects
of my Invention, but in order to make it more fully and exactly understood, I will
now proceed to describe the same by the aid of the drawings hereto annexed_and_
forming a part of the specification.
The drawings are marked with letters and figures of reference corresponding with
those used in the following explanation to denote the same or corresponding parts
throughout the several Figures

Figure 1 shows, in olevation, an appliance according to my Invention for cleaning
the bowls of tobacco pipes, Figure 2 is an end view; and Figure 3 is a section, taken
at X X Figure 1.
Figure 4 shows, in elevation, a modified construction of the appliance shown at
Figure 1.
Figure 5 is a section, taken at Y. Y; and Figure 6 15 a section, taken at Z Z.
Figure 4.
For the sake of clearness, the tool is drawn to a large size.
The appliance or tool, according to my invention, for cleaning the bowls of tobacco
pipes, is constructed in the form of a rimer, with two or more cutting edges, with
large intermediate grooves, and a rounded end or nose. .
In the example shown at Figures 1, 2 and 3, a is the rimer; are the cutting
edges; the said cutting edges are brought round the bottom of the rimer, where
they form a rounded end or nose. The other end of the tool is provided with a
shank and a handle d. The cutting edges project from the body of the rimer,
the part between the cutting edges being formed concave so as to provide for
clearance of the carbonaceous cake as it is scraped or rimed out. I find that
providing the tool with four cutting edges, and of an external diameter of about
of an inch, is a useful form and size, and the tool may be made of iron or steel
Losphur bronze or other suitable metal, and cast in one piece, as shown in
Figures 1, 2 and 3.
A modified form of the tool consists in constructing it of bar metal, in the form
of a cage, as shown at Figures 4, 5 and 6. In this case the edges of the bars b form
the scraping or cutting edges, the shank extends down to the end of the tool, to
which it is fastened by screwing or otherwise. At the top the bars are connected
by a plate h, having a square hole, through which the shank e passes, the shank
being square at the part and provided with a screw thread on which there is n
nut which bears on the plate h. By screwing down this nut the tool can be
expanded; and, by screwing the nut up, the spring of the bars will bring the tool
back to its normal size. The tool will thus serve for different sized bowls.
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 herein described improvements connected with the cleaning of the bowls
of tobacco pipes, consisting in the employment of a tool, having a plurality of cutting
or scraping edges, with large intermediato grooves, and adapted and constructed, to

page_text: fit the said bowl and bear on the surface thereof, at a plurality of points, and to cut
or scrape away the matter to be removed, gradually and evenly, by rotating such
tool.
2. A tool or appliance for cleaning the bowls of tobacco pipes, consisting of a body,
having a plurality of cutting edges, with large intermediate grooves, and a shank
and handle for turning or operating same; and also a tool as set forth with
reference to Figures 1, 2 and 3 of the Drawings
3. A tool or appliance for cleaning the bowls of tobacco pipes, consisting of a
plurality of bars (in the form of a cage) forming cutters, a shank, and handle for
turning and operating same, and a nut for expanding or contracting the cage; and
also the tool as set forth with reference to Figures 4, 5 and 6 of the drawings.
