We, STEPHEN APPLEBY, of No. 98, Parliament Street, Middlesbrough, in the County of
York, Contractor, and JouN GRIFFITH YOUNG, of Bank, Chambers, in the City of
Durham, Solicitor, do hereby declare the nature of this invention to be as follows:-
The invention relates to improvements in or connected with ingot moulds.
It has before been proposed to formn ingot moulds longitudinally divided into
two parts formed with flanges transversely. pierced to receive bolts or cotter pins by
the aid of which the parts were solidly connected together.
In moulds of this class the flanges of one part were formed with longitudinal
V-shaped beads or projections and the flanges of the other part were formed with
corresponding grooves or recesses in order to secure the parts against shifting.
This method of forming both grooves upon one part was a source of weakness
to the mould, and one of the objects of the presont invention is to remedy this
defect.
For this purpose, instead of forming both projections upon one part and both
grooves upon the other part, one part is provided with a projection or bead upon
one flange and with a groove or recess in the other flange and the other part is
formed to correspond therewith so that the weakening of the metal by the formation
of the grooves is divided between the two parts, and the construction of the mould as
a whole is strengthened.
A further object of the present invention is to pack the meeting joints of the
mould, whilst the two parts are united, by means of the usual grout and in such
manner that the latter will run well into the joint, and, whilst preventing the
formation of fins upon the ingot, will at the same time facilitate the stripping thereof
from the mould.
For this purpose, a half round groove is longitudinally formed in each flange of
ench part of the inould in a suitable position so that the mecting parts will form a
circular channel co-extensive with the mould and the grout is poured into this
channel and flowing into the joint closes the same against the passage of the fluid
metal, as will be readily understood.
The two parts of the mould may be connected together by cotter pins, bolts, or
other suitable means, and the transverse shape of the mould may be varied according
to requirements, whilst generally it would be formed longitudinally with a taper
sufficient to facilitate the stripping of the ingot without the necessity for separating
or loosening the two parts of the mould.
By the means herein before described, the strength of the mould is increased, and,
at the same time, the casting of more perfect ingots is facilitated.

of York, Contractor, and JOHN GRIFFITH YOUNG, of Bank Chambers, in the City of
Durham, Solicitor, 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:-
Our said invention relates to improvements in or connected with ingot moulds.
It has before been proposed to form ingot moulds longitudinally divided into two
or inore parts formed with flanges transversely pierced to receive bolts or cotter pius
by the aid of which the parts were solidly connected together.
In moulds of this class the flanges of one part were formed with longitudinal
Vor other shaped beads or projections and the flanges of the other part were
formed with corresponding grooves or recesses in order to secure the parts against
shifting.
This method of forming both grooves or recesses upon one part was a source of
weakness to the mould and one of the objects of the present invention is to remedy
this defect.
For this purpose, instead of forming both projections upon one part and both
grooves upon the other part, one part is provided with a projection or bead upon
one flange and with a groove or recess in the other flange and the other part is
formed to correspond therewith so that the weakening of the metal by the forination
of the grooves is divided between the two parts, and the construction of the mould
as a whole is strengthened.
A further object of the present invention is to pack the meeting joints of the
mould, whilst the two parts are united, by means of the usual grout and in such
manner that the latter will run well into the joint, and, whilst preventing the
formation of fins upon the ingot, will at the same time facilitate the stripping thereof
from the mould.
For this purpose, a half round groove is longitudinally formed in each flange of
cach part of the mould in a suitable position so that the meeting parts will form a
circular channel co-extensive with the mould and the grout is poured into this
chaunel, and flowing into the joint closes the same against the passage of the fluid
metal as will be readily understood.
The two parts of the mould may be connected together by cotter pins, bolts, or
other suitable means, and the transverse shape of the mould inay be varied according
to requirements, whilst generally it would be formed longitudinally parallel or with a
taper sufficient to facilitate the stripping of the ingot without the necessity for
separating or loosening the two parts of the mould.
And, in order that the said invention may be more clearly understood aud
readily carried into effect, we will proceed, aided by the accompanying drawings, more
fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1. is an elevation of an ingot mould constructed according to the present
invention.
Figure 2. is a plan thereof partly in section.
Figure 3. is a similar view to Figure 1 but taken at right angles thereto, and
with part broken away.
Figure 4. is a plan of one half of the mould separately.

page_text: Figuro 5. is a side view of one of the bolt washers separately.
Figure 6. is a plan thereof, and,
Figure 7. is an end view thereof.
In the several figures like parts are indicated by similar letters of reference.
a represents the body of the mould which is divided into two identical parts
formed with flanges a. thereon transversely pierced at a'. to receive bolts, cotter
pins, or the like by the aid of which the parts are solidly connected together as
hereinafter described.
In order to secure the two parts of the mould a. against shifting, according to the
present invention each part a. of the mould is provided with a projection or bead a³.
upon one face or flange a. and with a corresponding groove or recess u. in the other
face or flange, and the other part a. is formed with projections a³. and grooves a*. to
correspond therewith instead of as heretofore forming both projections a upon the
flanges a. of one part a. and both grooves a. in the flanges of the other part . and
thus the weakening of the inetal by the formation of the grooves a. is divided
between the two parts a. and the construction of the mould as a whole is
strengthening.
In order to pack the meeting joints of the mould by means of the usual grout
whilst the two parts are united and in such mauner that the same will run well
into the joint a half round groove a. is longitudinally formed in each flange a. of
each part a. of the mould in a suitable position so that the meeting parts will form
a circular channel co-extensive with the mould as shown at Figure 2, and the grout
is poured into this channel a. and flowing into the joints closes the same against
the passage of the fluid metal as will be readily understood, and whilst preventing
the formation of fins upon the ingot will at the same time facilitate the stripping
thereof froin the mould should the mould become burnt.
The two parts a. of the mould may be connected together by bolts, cotter pins, or
other suitable means, but the preferred ineans for this purpose consists of bolts b.
placed in any convenient position and at one end slotted to receive transverse
wedge-shaped pins c. and at the other end formed with heads b'. whilst in connection
with each of these bolts is employed a washer d. provided with a long slot d¹.
therein and formed with a step that is to say with a part d. of reduced height,
whilst the other part of the washer is at d', formed inclined or wedge-shaped for
the purpose hereinbefore described.
By the employment of a washer of the form lastly described, it is unnecessary to
dismount the bolts b. or to drive out the pins c. in order to separate the two parts
of the mould a. sufficiently to discharge the ingot but in lieu thereof the washers d.
are driven back until the reduced parts thoreof d. come under the bolt heads b'. when
the two parts . of the mould may be separated to a considerable extent without any
of the parts becoming actually disconnected.
The two parts of the mould a. may be readily restored to their normal or closed
position by driving the inclined raised parts d'. of the washers under the heads b¹. of
the bolts b.
Or, in lieu of the form of washer lastly hereinbefore described a plain wedge
shaped but slotted washer might be substituted therefore as will be readily
nuderstood.
The transverse shape of the mould a. may be varied according to requirements
that is to say according to the shape to be given to the finished article, but
generally it would be formed parallel longitudinally as that is the preferred form
although it might be formed with a taper sufficient to facilitate the stripping of the
ingot or even sufficient to dispense with the necessity for separating or loosening the
two parts a. of the mould.
By the means hereinbefore described, the strength of the mould is increased, and
at the same time the casting of more perfect ingots is facilitated whilst the ingots
may be cast of any desired transverse shape such for example as bulb, tee or
section.

page_text: 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. An ingot mould formed in two or more parts each provided on its meeting
face at one side with a projection or bead and at the other side with a corresponding
groove or recess, substantially as herein showu and described and for the purpose
stated.
2. An ingot mould formed in two or more parts each provided on its meeting face
at each side with a half round groove so that in the closed condition of the meeting
parts the grooves will form circular channels to receive grout, substantially as herein
shown and described and for the purpose stated.
3. An ingot mould formed in two or uiore parts connected together by means of
bolts and inclined and stepped or wedge shaped or equivalent slotted washers acting
in manner substantially as herein shown and described and for the purpose stated.
