PROVISIONAL SPECIFICATION.
Improvements in the Construction of Ingot Moulds.
We, BARTLETT WRANGHAM WINDER, 43 Broomhall Place, Steel Manufacturer,
and JOHN MUXLOW 29 Fir Street, Steel Melter, both of Sheffield in the County
of York, do hereby declare the nature of our invention to be as follows:-
Our invention relates to ingot moulds for producing compound ingots such as
are known in the trade as plated and gated ingots, and also other forms of compound
ingots.
The object is to avoid the necessity of using an ingot mould that requires to be
made in two parts, which require to be opened or separated, and to obtain rapidity
of action and certainty of result in adjusting and removing the plates or like
intermediate partition pieces.
We propose to use an ingot mould the body of which is made in one piece, but
it may be made in several parts secured together by rings and wedges in the
usual way.
In a mould for producing a plated ingot that is an ingot of two qualities of steel
for example, we make the sides of the interior slightly tapering towards the end at
which the plate, or facing of best steel or other metal is to be situated, and we make
the partition plate with its edges bevelled or tapered to fit against the mould sides
in the position which will leave the required space from the end, or we may
determine this space by a vertical shoulder against which the plate may abut.
The division plate is held up to its position by the pressure of a compound or
double wedge driven in between the back of the plate and the opposite side of the
mould, and to guide and retain the said wedge in its place, we prefer to cast upon
the back of the plate, a vertical groove, or its equivalent, in which the edge of the
wedge will slide easily.
The compound wedge consists of two long wedge shaped pieces of metal, the
bevelled edges of which fit together, and preferably are retained in such position
by means of a. longitudinal tongue and groove which prevents a transverse movement
only.
When this double wedge is placed in the mould at the back of the division piece
and the small end of one part of the wedge is raised, the plate becomes wedged fast
in its position, and it may be further tightened and secured by means of a wedge
or cotter being passed through it.
To release all the parts for the removal of the plate, a blow upon the raised end
of the wedge is all that is necessary, this causes it to drop when the various pieces
can be withdrawn.
The plate is made to project above the top edge of the mould, so that it may be
readily got at.
One part of the wedge may be cast. upon the back of the division plate if
preferred.

page_text: We BARTLETT WRANGHAM WINDER, 43 Broomhall Place, Steel Manufacturer,
and JOHN MUXLOW 29 Fir Street, Steel Melter, both of Sheffield in the County
of York, do hereby declare the nature of this invention and in what manner the
same has to be performed, to be particularly described and ascertained in and by
the following statement :-
Our invention relates to ingot moulds for producing compound ingots, such as
are known in the trade as plated and gated ingots, and similar forms of compound
ingots.
The object is to avoid the necessity of using an ingot mould made in two parts
which have to be opened or separated during the process of casting the ingot, and
we thereby accomplish the process with rapidity and obtain a better result and
superior product.
Our improvements are illustrated in the annexed sheet of drawings in which:
Fig. 1, is an elevation of a mould with one side removed to show the interior.
Fig. 2, plan of same.
We propose to use an ingot mould having its body cast in one piece by preference,
but it may be made in several parts secured together by rings and wedges in the
usual manner.'
In a mould for producing a plated ingot or an ingot having a face of best steel
and a back of inferior quality for example, such as the one illustrated, we make
the body A, in one casting, either with or without the base plate B.
The sides of the mould marked C, are made to taper or contract towards that
end in which the facing of best quality steel is to be cast, the space for which is
marked F.
We separate this space by a partition plate D, having its vertical edges bevelled
to fit against the sides of the mould, in the position required, or we may determine
this space by a strip cast upon or fitted to each side of the mould, against the end
of which at E, the plate D, will abut.
The division plate is held up to its position by the pressure of a double
wedge G & H, fitting between the back of the plate D, and the back of the
mould A, and to retain the part G, in position we cast upon the back of the plate
two strips S, between which the edge of the plate will slide easily, and there may
also be a tongue and groove upon the edges of the wedges G & H, where they bear
against each other but this is optional.
The compound wedge consists of two long wedge shaped pieces of metal, the
tapered edges of which fit together, the piece H, is preferably longer than the
piece G, and its top end by which it is removed from the mould, may in some cases
be provided with a slot hole through which a key or wedge I, can be driven.
When the division plate D, is placed in the mould as shown, the double wedge is
put in its groove which terminates at some little distance from the bottom forming
a stop J, for the piece G, to rest upon.
The piece H, is raised sharply by hand, and wedges all the parts in position, and
the key I, may be driven through the top of piece H, to give absolute security, and
increase the force of the wedges.
When the first casting is made in the part F, the key I, is withdrawn, and a blow
upon the top of the piece H, causes it to drop and release both G and D, which
can be at once removed and the second casting made in the back space.
The part G, may if desirable be cast upon the plate D.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1. An ingot mould with a removable division plate, secured in position by &
double wedge, as herein before described and shown.
"
2. An ingot mould made with its side C, converging towards the front or "face
end, and provided with a division plate D, held to its position by a double
wedge G, H, acting between the back of the mould and the division plate, as.
described & shown.
3. In an ingot mould having a movable division plate, the use of a double-
wedge to hold the said division plate to its position, as hereinbefore described and
set forth.
