Year: 1868

page_text: LETTERS PATENT to Anthony Wilson, of Barrow-in-Furness, in the
County of Lancaster, Pattern Maker, for the Invention of "IM-
PROVEMENTS IN METALLIC MOULDS FOR CASTING METALS."
Sealed the 16th April 1869, and dated the 28th October 1868.
PROVISIONAL SPECIFICATION left by the said Anthony Wilson at
the Office of the Commissioners of Patents, with his Petition, on
the 28th October 1868.
I, ANTHONY WILSON, of Barrow-in-Furness, in the County of
Lancaster, Pattern Maker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN METALLIC MOULDS FOR CASTING METALS," to
be as follows:-
My Invention consists in making metallic moulds for casting metals
in the manner herein-after described, whereby the entrance of air
through the junctions of the parts of the moulds during the use of the
said moulds is obviated and a sound casting thereby produced.
My Invention is particularly applicable to metallic moulds made in
two parts or halves for casting steel ingots, but may also be applied to

page_text: metallic moulds for casting other metals and articles, and also to metallic
moulds made in more than two parts.
My said Invention consists in the formation of a cavity at each of
the junctions or joints of the parts of the metallic mould, and filling the
said cavity with sand, fire-clay, or other fire-proof material. By the
use of the cavity described and filling material a perfect air-tight joint
is formed at the junction of the parts of the metallic mould, and the
entrance of air through the said junctions into the metal cast in the
mould is prevented.
In making a mould for casting steel ingots, according to my Invention
I make along the whole length and at the outside of the joints or
junctions of the two parts of the mould an opening or cavity of the
required size to hold the sand or other filling material employed; I
cover the said cavity at the junction by means of a metallic cover strap
or plate which I fasten in its place on the outside of the mould by the
clips used for holding the halves of the mould together or by any other
convenient mechanical arrangement. When the cavities described are
filled with sand, wood, or other filling material a core is formed along
the whole length of the joints of the mould. Or, instead of forming the
cavity by making a depression on the outside of the junction of cach
half mould and covering it by a cover, strap, or plate,, the cavity may be
made in the half moulds themselves either by casting them in the half
moulds or fixing pieces to the half moulds. In this case apertures or
holes may be left to carry off the heated air from the sand or stopping
employed in the cavity while the ingot is being cast.
I do not limit myself to the methods described, of making the cavity
at each of the junctions of the mould as the said cavity may be made
in various ways with the same or nearly the same effect.
SPECIFICATION in pursuance of the. conditions of the, Letters Patent,
filed by the said Anthony Wilson in the Great Seal Patent Office 30
: on the 22nd April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTHONỲ
WILSON, of Barrow-in-Furness, in the County, of Lancaster, Pattern
Maker, send greeting.

particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months.
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Anthony Wilson, do hereby declare
tlic nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
:
My Invention consists in making metallic moulds for casting metals
in the manner herein-after described whereby the entrance of air through
the junctions of the parts of the moulds during the use of the said
moulds is obviated and a sound casting thereby produced.
My Invention is particularly applicable to metallic moulds made in
two parts or halves for casting steel ingots, but may also be applied to
metallic moulds for casting other metals and articles, and also to
metallic moulds made in more than two parts.
My said Invention consists in the formation of a cavity at cach of the
junctions or joints of the parts of the metallic mould, and filling the
said cavity with sand, fire-clay, or other fireproof material. By the use
of the cavity described and filling material a perfect air-tight junction is
formed and the entrance of air through the said junction into the metal
cast in the mould is prevented.

page_text: In making a mould for casting steel ingots according to my Invention
I make along the whole length and at the outside of the joints or
junctions of the two parts of the mould an opening or cavity of the
required size to hold the sand or other filling material employed. I
cover the said cavity at the junction by means of a metallic cover,
strap, or plate, which I fasten in its place on the outside of the mould
by the clips used for holding the halves of the mould together, or by
any other convenient mechanical arrangement. When the cavitics
described are filled with sand, wood, or other. filling material, a core is
formed along, the whole length of the joints of the moulds. Or, instead of
forming the cavity by making a depression on the outside of the junction
of cach half mould and covering it by a cover, strap, or plate, the
cavities may be made in the half moulds themselves, either by casting
them in the half moulds or fixing picces to the half moulds. In this
case apertures or holes may be left to carry off the heated air from the
sand or stopping employed in the cavity while the ingot is being cast.
I do not limit myself to the methods described of making the cavity
at each of the junctions of the mould as the said cavity may be made in
various ways with the same or nearly the same effect.
Having explained the nature of my Invention I will proceed to
describe with reference to the accompanying Drawings the manner in
which the same is to be performed.
Figure 1 represents in vertical section, and Figure 2 in plan a metallic
mould for casting steel ingots made in two parts, the said mould con-
taining my improvements. a, b, are the two parts or halves of the
mould; c, c, are the cavities made along the whole length of the
junctions of the said parts a, b; and d, d, is the sand or other filling
material placed in the cavities c, c. The said cavities c, c, are covered
by the metallic covers, straps, or plates e, e, the said covering plates
having the Figure best seen in the plan, Figure 2. The said plates e, e,
run the whole length of the mould and are fastened in their places on the
outsides of the mould by the ordinary clips ff, used for holding the
halves a, b, of the mould together. Other convenient arrangements,
however, may be used for holding the covering plates e, e, in their
places. By the use of the cavities and filling material described a
perfect air-tight joint is formed at the junctions of the parts of the
mould and the entrance of air through the said junctions into the metal
cast in the mould is prevented.

page_text: Figure 3 represents in vertical section, and Figure 4 in plan another
arrangement of my Invention for effecting the same object. In this
arrangement I dispense with the covering straps or plates outside the
mould, and I make the cavities in the parts of the mould themselves as
represented at g, that is, in cach of the inner faces of the junctions of the
two parts a, b, of the mould is a depression which when the said parts
are put together form the cavities g. The said depressions g in tho
halves of the moulds are either made by casting them in the said halves
or the half moulds may be cast without the depressions g. In this caso
the edges of the mould coming together are not cast with the half
moulds, but are formed separately and affixed to the half moulds by
screws or otherwise. Or, the edges of the half moulds may be cast with
dovetail recesses in them into which pieces may be driven, the said pieces
having depressions which when put together form the cavities g; h, h,
are apertures or holes left in the half moulds to carry off the heated air
from the sand or filling material in the cavities while the ingot is being
cast.
"
Instead of employing sand or other non-metallic material in the
cavities of the mould as previously described metallic rods of any required
sectional figure may be used, as illustrated in the horizontal section of a
mould, Figure 5, where the said metallic rods are marked i and the
cavities are marked k. These rods i are compressed by the cotters
fastening the halves a, b, of the mould together, and the said rods are
thereby made to fill up the junctions of the mould and prevent the
entrance of air. Figure 6 represents one half of the mould Figure 5.
Or, instead of making a depression in each of the edges of the half moulds
a depression may be made in one of the edges only of the half moulds,
and the rod of metal engaging therein may be inserted and fixed on the
edge of the other half mould. In this case case I prefer to attach the
rod of metal by a dovetail at its back taking into a dovetail depression in
the edge of the mould, and by means of screws fixing the rod in the said
dovetail depression. When the said rod has become worn by use it may
be removed by relaxing the set screws and a new rod may be introduced
into the dovetail and fixed by the set screws.
The last described modification of my Invention may also be applied to
the lower part of the inner faces of the mould for the purpose of
applying preservative plates thereto as well as to the edges or junctions
of the mould, as illustrated in horizontal section in Figure 5, where the

page_text: preservative plates are marked 7. The said plates as will be seen from
the Drawing are so shaped that when one face has become worn the
plates may be removed and the unworn face turned towards the inside of
the mould. The shape of the recesses in which the plates / fit will be
understood by an examination of Figure 6. The plates I may be fixed t
by set screws m. By the use of these prescrvative plates the lower part
of the mould is kept in good condition much longer than is practicable
in moulds: of the ordinary kind, the renewal of the plates rendering
the mould fit for use which otherwise would have to be thrown away.
Figure 7 represents in horizontal section and Figure 8 in perspective 1
a solid mould, that is, a mould made in one piece containing preservative
plates fixed by set screws m.
Figures 9, 10, and 11 represent a conical mould having a removeable
and preservative lining according to my Invention; Figure 9 being a
plan of top, Figure 10 a vertical section; and Figure 11 a plan of the
lower part. The two halves of the lining are marked n. These are
fixed in position by the dovetail picces o and set screws p. The lining
represented in Figures 10 and 11 may be made in one piece as illustrated.
in Figure 12.
Figure 13 represents in elevation and Figure 14 in plan a pyramidal
mould provided with a lining in one piece. In moulds of this kind
portions of them may be removed at the back of the lining as indicated.
at for the purpose of rendering the mould' lighter and keeping the
lining cool..
Figure 15 represents a plan of top; Figure 16 a vertical section; and
Figure 17 a plan of the base of a pyramidal mould in which the lining is
made in four pieces connected together by dovetails and set screws as
represented.
Having now described the nature of my Invention, and the manner
in which the same is to be performed, I wish it to be understood that I
do not limit myself to the precise details herciu described and illustrated
as the same may be varied without departing from the nature of my
Invention; but I claim as my Invention of improvements in metallic
moulds for casting metals,―
Firstly. The formation of a cavity at each of the junctions or edges of
parts of the mould and filling the said cavity with sand, fire-clay, wood,
or other material whether non-metallic or metallic, substantially as aud

page_text: for the purpose herein-before described and illustrated in the accom-
panying Drawings.
Secondly. Making a groove in one of the two edges of the mould and
attaching to the other edge a filling up metallic bar or piece attached to
the edge of the mould by a dovetail and set screws, and, the application
of the said method of attachment to the fixing of preservative metallic
plates or linings to the lower parts of metallic moulds, substantially as
and for the purpose herein-before described and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said Anthony Wilson, have hercunto
set my hand and seal, this Twenticth day of April, in the
year of our Lord One thousand eight hundred and sixty-nine.
