PROVISIONAL SPECIFICATION.
Improvements in Appliances for Preparing the Ends of Lead Pipes
for "Jointing."
We FREDERICK JAMES BAILEY, Ironmonger, of Swan Street, Bawtry,
Yorkshire, and ALFRED BAILEY, Ironmonger, of Chapel Street, Epworth,
Lincolnshire, do hereby declare the nature of this invention to be as follows:-
This invention is for improvements in appliances for preparing the ends of lend
pipes preparatory to jointing-i.e. soldering the ends together.
It is usual joining together the ends of pipes to insert the end of one pipe into
that of the other and then to solder the parts together, and to accomplish this one
end must be enlarged and the other contracted, and it is also necessary that the
parts to be soldered should be perfectly clean.
These operations have hitherto been accomplished by means of a wooden plug of
tapering form to be driven into the end of one pipe in order to expand it, a knife
being used to taper the end of the other pipe and to scrape or pare the pipes clean.
We propose in carrying out our invention to construct a tool (preferably made of
sheet steel) and which we call a jointer, by bending the steel to the required form
one part forming a cone to be put inside the pipe and having one of its edges where
they come together, made sharp after the manner of the well known lead pencil
sharpener, so that when the cone is inserted into the pipe and turned round it will
pare the inside of the pipe away in a conical form.
Another cone of similar construction is made to fit over the end of the pipe, so
that when turned round and pressed upon it, it will also cut away the outside of the
pipe conically.
We prefer to combine the two described parts together in the form of a T, so
that one part will act as a handle to the other. Suitable apertures are arranged
for the ready escape of the cuttings.
We may if we prefer it cast the body in metal and attach the cutting edges.

for Jointing."
We, FREDERICK JAMES BAILEY, Ironmonger, of Swan Street, Bawtry,
Yorkshire, and ALFRED BAILEY, Iroumonger, of Chapel Street, Epworth,
Lincolnshire, 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 is for improvements in appliances for preparing the ends of lead
pipes preparatory to jointing-i.e. soldering the ends together.
It is usual in joining together the ends of pipes to insert the end of one pipe into
that of the other and then to solder the parts together, and to accomplish this, one
end must be enlarged and the other contracted, and it is also necessary that the
parts to be soldered should be perfectly clean.

These operations have hitherto been accomplished by means of a wooden plug of
tapering form to be driven into the end of one pipe in order to expand it, a pocket
knife being commonly used to taper the end of the other pipe, and to scrape or
pare the pipes clean.
The annexed sheet of drawings clearly illustrates our invention-which is an
improvement upon the old appliances.
Fig. 1, is an elevation and other views of the improved jointer.
Fig. 2, the jointer and method of using it.
We propose in carrying out our invention to construct a tool (preferably made of
sheet steel) and which we call a "jointer," by bending the steel to the required
form one part forming a cone A, to be put inside the pipe and having one of its
edges B, where they come together, made sharp after the manner of the well
known lead pencil sharpener, so that when the cone is inserted into the pipe and
turned round it will pare the inside of the pipe away in a conical form.
Another cone C, of similar construction is made to fit over the end of the pipe,
so that when turned round and pressed upon it, it will also cut away the outside of
the pipe conically.
We prefer to combine the two described parts together in the form of a T, as
shown in the drawings D, and A, so that one part will act as a handle to the other
part G, and vice versa suitable apertures E, are arranged for the ready escape of
the cuttings, but we may make them separately if desired.
We may if we prefer it cast the body of each part in metal and attach the cutting
edges.
We do not limit our invention to the precise form shown, as the position of the
two conical cutters may be varied, but :-
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A tool or "jointer"-for the purpose specified-consisting of two cones A and C,
having suitable cutting edges for coning or bevelling the ends of lead pipes,
substantially as hereinbefore described and illustrated.
