IMPROVED MOULDING APPARATUS FOR CAST-IRON INGOTS AND OTHER CASTINGS
Year: 1870

page_text: LETTERS PATENT to John Westray, of the Firm of Westray and
Forster, of Barrow-in-Furness, in the County of Lancaster,
Engineer, for the Invention of "IMPROVED MOULDING APPARATUS
FOR CAST-IRON INGOTS AND OTHER CASTINGS."
Sealed the 25th April 1871, and dated the 27th October 1870.
PROVISIONAL SPECIFICATION left by the said John Westray at the
Office of the Commissioners of Patents, with his Petition, on the
27th October 1870.
I, JOHN WESTRAY, of the Firm of Westray and Forster, of Barrow-in-
Furness, in the County of Lancaster, Engineer, do hereby declare the
nature of the said Invention for "IMPROVED MOULDING APPARATUS FOR
CAST-IRON INGOTS AND OTHER CASTINGS," to be as follows:-
My improved moulding apparatus for cast-iron ingots and other
castings consists of a base and top plate, between which the moulding
box is secured by means of bolts passing through both. The moulding

page_text: box is made in two halves secured together, and may be round or other
shape as required. The ends of the mould box and the top and bottom
plates form faced joints. The core bar, which is hollow and perforated,
forms a faced joint with the bottom plate and passes through the top
plate. The bottom plate is also open in the middle. The moulding box
is kept in position with the core bar so as to produce a uniform thick-
ness of casting by means of turned pins fitting into bored holes. The
pattern of the casting fits upon the base plate, and is held in a uniform
position with regard to the core bar by means of brackets having pins
fitting into bored holes. Iron templates are fitted to the ends of the box
corresponding with the loam lining of the mould box, that is, the outside
of the pattern.
The method of moulding by means of this apparatus is as follows:-
The pattern is placed on the base plate, which has previously been
coated with loam and with the hay banded core bar in position. The
space between pattern and core is then filled with moulding sand
rammed down in the usual way. On withdrawing the pattern the centre
of the mould may be blackened and finished in the usual way. The iron
templates are then fixed to the ends of the box and loam put on. A
strickle or straight edge being passed round the inside of the box
against the templates ensures an even layer being put on.
The top
plate is also coated with loam. The separate parts of the mould are
then dried in the usual manner, and when placed together in position
are ready to receive the molten metal which is poured in the usual
manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Westray in the Great Seal Patent Office on
the 27th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WESTRAY, of the Firm of Westray and Forster, of Barrow-in-Furness, in
the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of October, in
the year of our Lord One thousand eight hundred and seventy, in the

page_text: the box corresponding with the loam lining of the moulding box, that
is, the outside of the pattern.
Figure 1 of the accompanying Drawings is a view in vertical section;
Fig. 2 is a view in plan, Fig. 3 is an elevation, and Fig. 4 is a horizontal
section of moulding apparatus for cast-iron ingots and other castings
constructed according to my Invention.
A is the base plate faced to receive the core bar C, and the moulding
box B here shewn made in halves, fitted together as shewn. The core
bar C is fixed to the base plate A. The moulding box B is fastened with
bolts through flanges running the full length, and is kept in position
with the core bar so as to produce a uniform thickness of casting by
means of turned pins fitting into bored holes. D is the top plate which
is faced and rests upon the faced surface of the box, as shewn. The
pattern of the casting fits upon the base plate, and is held in a uniform
position with regard to the core bar by means of brackets, holding pins
fitting into bored holes. To the end of the box iron templates are
fastened corresponding with the lines E, E.
The method of moulding by means of this apparatus is as follows :-
The pattern is placed on the base plate A, which has previously been
coated with loam with the core bar C in position, which is previously
wrapped with a hay band or bands. The space between pattern and core
is then filled with moulding sand rammed down in the usual way.
On
withdrawing the pattern the centre of the mould may be blackened
and finished in the ordinary manner. The iron templates are then fixed
to the ends of the box and loam put on. A "strickle" or straight edge
being passed round the inside of the box against the templates ensures
an even layer being put on. The top plate is also coated with loam.
The separate parts of the mould are then dried in the usual manner, and
when placed together in position are ready to receive the molten metal
which is poured in the usual manner.
By the use of apparatus before described cast-iron ingot moulds or
other castings may be moulded round, square, hexagonal, or of any
other required form.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim as my
improved moulding apparatus for cast-iron ingots and other castings,

page_text: the construction and employment of a moulding box in pieces, with top
and bottom covers and a hollow perforated core bar, all substantially as
herein-before described and illustrated in the accompanying Drawings.
In witness whereof, I, the said John Westray, have hereunto set
my hand and seal, this Twenty-second day of April, in the year
of our Lord One thousand eight hundred and seventy-one..
