PROVISIONAL SPECIFICATION.
Improvements in Appliances for Bending and Shaping Lead Pipes.
1, JAMES WALTER WILSON of 5 Alacross Villas, South Ealing, Plumber, do hereby
declare the nature of this invention to be as follows:-
This invention consists of an appliance for bending or shaping lead pipes after the
pipes are fixed, or when the pipes are in a position difficult to reach, or for making
traps in pipes without the necessity of making a joint.
The appliance consists of a number of cheese shaped plugs, made of any suitable
material, preferably of box-wood, bored through the centre and threaded on to a cord
of sufficient length to allow of the plugs or wood sections running loose. These plugs
are made about one inch in thickness and of the same diameter as the inside diameter
of the pipe to be bent or shaped. The appliance or tool umy consist of any number
of these plugs, but for a pipe of from 1 to 2 in diameter it is found that from
twenty six to thirty plugs is a convenient number.
A ram for forcing the plugs into the pipe is provided in the form of a circular rod
of boxwood or any suitable material about 18' in length and grooved slightly at one
end so as to allow play to the cord ranning through the plugs. When it is desired to
make a bend in a pipe, the pipe is placed in the position required and roughly bent to
the required angle, the plugs on the rope are then driven through the pipe one after
the other, going through the bend or curve in the form of a flexible rod. Should the
bend required be at a distance of from three to ten foot from the end of the pipe, it
may be necessary to uso a length of iron tube or other tool to force the wood plugs
through the curve. When the bend has been made, the plugs are drawn out by
means of the rope.

Improvements in Appliances for Bending and Shaping Lead Pipes.
I, JAMES WALTER WILSON of 5 Alacross Villas, South Ealing, Plamber, 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 consists of an appliance for bending or shaping lead pipes after
the pipes are fixed, or when the pipes are in a position difficult to reach, or for
making traps in pipes without the necessity of making a joint.
The appliance consists of a number of cheese shaped plugs made of any suitable
material, preferably box wood, and bored through the centre to allow of the said
plugs being threaded on a suitable cord, the diameter of the plugs being made to
suit the bore of the pipe to be manipulated. The number of said plugs may vary

page_text: with circumstances, but it will be found that for pipes of 1 to 2 inches, twenty six
to thirty plugs are most convenient.
A ram for forcing the plugs into the pipe is provided, and where the bend is
situated at some distance from the end of the pipe, a jointed hollow tool is
provided.
In order that the nature of this invention may be the more easily understood,
I have appended the accompanying sheet of drawings, in which
Fig. 1. shows a tube having the improved applianco inserted therein.
Fig. 2. is a view on an enlarged scale, and partly in section, shewing more
particularly the configuration of the plugs upon the cord.
Figs. 3 and 4 are respectively a side and end elevation of the ram for forcing
the plugs into the pipe, oud
Figs. 5 and 6 are respectively a longitudinal section and ond view of the apparatus
-employed, when the bend is situated at some distance from the end of the tube.
A. are the plugs which may be of any suitable material and size, having a central
orifice B. through which passes a cord C. one end of which is knotted, a rocess
or chamber D. being formed in the end plug, as shewn in Fig. 2. to receive same.
E. (Figs. 3 and 4) is a ram which may be of wood or other suitable material,
and of any convenient length, being slightly tapered at the forward end as shown
at F. and having a recess or channel G. formed therein to receive the cord when
forcing the plugs into the pipe.
In Figs. 5 and 6 is shewn a tool consisting of a metal barrel H. having a socket I.
scrowed on at one end, which carries a brass or other metal plug J. which has a
central orifice K. through which passes the cord, as shewn, and is also provided
with a screw thread which engages with a corresponding thread formed within the
socket I.
When it is desired to make a bend in a pipe, the pipe is placed in position, and
roughly bent to the required anglo; the plugs are then driven through the pipe one
after the other, going through the tube in the form of a flexiblo rod. Where the
ibend is a long distance from the end of the pipe, the jointed tubular apparatus is
employed to place the plugs in position. This tubular apparatus may consist of a
piece of ordinary gas pipe, into the end of which may be screwel the brass plug J.
When the bend has been made, the plugs are withdrawn by means of the cord C.
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 :-
The improved tool or appliance for bending and shaping pipes, substantially as
-described and set forth in the foregoing specification and drawing.
