Complete Accepted, 29th July, 1887.
We, MILES CORNTHWAITE and JOHN CORNTHWAITE, both of Parton, near
Whitehaven, in the county of Cumberland, Ironfounders, do hereby declare the
nature of this invention to be as follows :-
This invention relates to further improvements in the machinery for manufacturing
moulds for casting pipes for which Letters Patent were granted to us dated the
3rd June 1885 No. 6757, the object of the present improvements being to provide
means for making the mould for the faucet or flange of such pipes in the same mould
box as that for forming the mould for the body of the pipe.
For this purpose we provide the carriage of the mould box with a cylindrical
casting in which is a piston adapted to be moved up and down by means of a screw;
the faucet or flange pattern formed hollow is attached to the said piston and when the
latter has been lowered in the casting the finishing piece or print is lowered into the
faucet or flange pattern. The sand is then commenced to be run into the moulding
box, the machine is set in motion and the piston and pattern are raised until the top
of the piston is flush with the top of the carriage thereby pressing the sand into the
required form.
The top dish is adapted to form the spigot end of the mould as also the well for
running in the metal; when the moulder has lifted the top dish the faucet pattern is
lowered down and the mould box is lifted off; the carriage and the faucet or flange
pattern is then again ready for use.

page_text: Improvements in Machinery for Manufacturing Moulds for
Casting Pipes or Tubes.
We, MILES CORNTHWAITE and JOHN CORNTHWAITE, both of Parton, near
Whitehaven, in the county of Cumberland, Ironfounders, 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 relates to further improvements in the machinery for manufacturing
moulds for casting pipes for which Letters Patent were granted to us dated the
3rd June 1885, No. 6757, the object of the present improvements being to provide
means for making the mould for the faucets or flanges of such pipes in the same
mould box as that for forming the mould for the body of the pipe.
For this purpose we provide the carriage of the mould box with a cylindrical
casting in which is a piston adapted to be moved up and down by means of a screw;
the faucet or flange pattern formed hollow is attached to the said piston.
The top dish adapted to form the spigot end of the mould as also the well for
running in the metal.
In order to enable our invention to be fully understood we will proceed to describe
how it can be carried into practice by reference to the accompanying drawing in
which figure 1 represents a sectional elevation illustrating a mould box and carriage
as arranged for making the mould for the faucet or flange of a pipe or tube in the
same mould box as that for forming the mould for the body of the pipe or tube
according to our present improvements; figure 2 is a vertical section taken at right
angles to figure 1; figure 3 is a detached plan view of the dish which we use with
this form of mould box; figure 4 is a vertical section of part of the mould box and
mould with the core placed therein. Similar letters in all the figures represent
similar parts.
a, is the cylindrical casting with which we now provide the carriage b, of the
mould box c; d, is the piston which is adapted to be moved up and down in the
cylindrical casting a, by means of a screw e, operated by bevil gear f, and a hand
wheel g; h, is the faucet or flange pattern formed hollow as shewn in figure 1 and
attached to the piston d, and when the piston has been lowered in the casting a, the
finishing piece, and print j, are lowered into the faucet or flange pattern. The sand
is then commenced to be run into the moulding box c, the machine is set in motion
and the piston d, and pattern h, are raised until the top of the piston d, is flush with
the top of the carriage, b, thereby pressing the sand into the required form as shewn
clearly in figure 2. The screw e, is provided with a nut al, on the end through which
a pin b¹, is placed to prevent the piston d, from moving above the level of the
carriage b, and to cause the piston d, and faucet pattern h, to rotate after being moved
up to their place thereby freeing the pattern from the sand. k, is the top dish adapted
to form the spigot end of the mould as also the well hereinafter referred to for running

page_text: in the metal. The spigot end of the mould is made conical or bell-mouthed as shewn
in figure 4 and is thus formed by the dish k, which extends down into the moulding
box c.
The space between the dish and the inside of the moulding box is rammed up
through holes l, l, in the dish during the time the moulder m, is running up from the
bottom so that there is no stoppage in the operation.
When the moulder m, has lifted the dish k, the faucet pattern h, is lowered down
and the mould box c, is lifted off; the carriage b, and the faucet or flange pattern h,
are then again ready for use.
The mould is stopped off the desired length by a cake, ring or belt n, on or around
the core as shewn in figure 4.
The well o, formed above the cake n, is for running in the metal and the
enlargement below the cake forms the spigot end of the pipe, which is generally made
a few inches longer than is necessary and is cut off afterwards in the lathe, this being
done to insure the casting being sound.
p, represents an Archimedean screw arrangement for introducing the sand into the
mould box the sand being fed thereto from a suitable source not shown in the
drawing.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. In machinery for manufacturing moulds for casting pipes or tubes the combina-
tion with a mould box and carriage of suitable construction of a hollow flange pattern
adapted and operated in such a manner as to allow of the mould for the faucet or
flange of such pipes being made in the same mould box as that for forming the
mould for the body of the pipe substantially as herein before described.
2. The improved machinery for making moulds for casting pipes or tubes herein-
before described and represented in the accompanying drawing.
