Improvements in Means or Apparatus to Facilitate the Manufacture
of Moulds for use in Casting Moulds for Ingots of Steel or other
Metal.
We ROBERT EVANS of the firm of John Evans & Sons, of Copper House
Foundry, Landore, in the County of Glamorgan, Iron Founder, and EVAN DAVIES
of the same place, Moulder, in the employ of the said firm, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object the production with greater economy and
celerity, of moulds, usually of cast iron, for use in casting ingots of steel or other
metal, by means of apparatus designed to save labour and time in the manufacture
of moulds therefor.
In carrying out the invention means or apparatus is employed consisting of
suitable framing, guides and supports, between two platforms, for a travelling plate,
which supports a core or pattern arranged to travel into position within a moulding
box supported on the upper platform, through an opening therein and when the
mould has been formed suitable for the purpose-casting the body of an iron ingot
mould this core or pattern is caused to descend and leave the mould ready for
removal without endangering its entirety.
Counterbalance weights or their equivalent support the plate carrying the core
or pattern.
:
Chains or their equivalents are employed to connect the plate with a winch to
draw the core away from its moulding position, pulleys being provided for the
connections to run over.
Suitable pins or studs serve to facilitate and preserve correct relative positions of
the parts and the connections by lugs and bolts.
:
The top, or cover, of the mould, preferably, is formed in an open frame with lugs
and bolt holes, over which is a plate with guide pins, and supported underneath by
the reversible platform to be described.
The bottom of the mould for the cast iron mould for the steel ingot is formed of
a platform supported on an axis or trunnions and on this plate is a frame having
lugs with holes to engage guide pins on the platform and also others on the cover
applied to the frame. The frame is locked to the platform by means of buttons or
catches so that the platform may be reversed on its axis and with it the mould and
then the mould may be released by handles on the axes of the catches being
turned.
The upper platform may be detachable and removable for substitution of other
parts or sizes of parts for variation in dimensions of moulds to be made.

page_text: 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 has for its object the production with greater economy and
celerity, of moulds, usually of cast iron, for use in casting ingots of steel or other
metal, by means of apparatus designed to save labour and time in the manufacture
of moulds therefor.
In carrying out the invention means or apparatus is employed consisting of
suitable framing, guides and supports, between two platforms, for a travelling plate,
which supports a core or pattern arranged to travel into position within a moulding
box supported on the upper platform, through an opening therein and when the
mould has been formed suitable for the purpose-casting the body of an iron ingot
mould-this core or pattern is caused to descend and leave the mould ready for
removal without endangering its entirety.
Counter balance weights or their equivalent support the plate carrying the core
or pattern.
Chains or their equivalents are employed to connect the plate with a winch or
other convenient power to draw the core away from its moulding position, pulleys
or rollers being provided for the connections to run over.
Suitable pins or studs serve to facilitate and preserve correct relative positions
of the parts and the connections by lugs and bolts.
The top, or cover, of the mould, preferably, is formed in an open frame with lugs
and bolt holes, over which is a plate with guide pins, and supported underneath by
the reversible platform to be described.
The bottom of the mould for the cast iron mould for the steel ingot is formed of
a platform supported on an axis or trunnions and on this plate is a frame having
lugs with holes to engage guide pins on the platform and also others on the cover
applied to the frame.
The frame is locked to the platform by means of buttons or catches so that the
platform may be reversed on its axis and with it the mould and then the mould
may be released by handles on the axes of the catches being turned.
The upper platform may be detachable and removable for substitution of other
parts or sizes of parts for variation in dimensions of moulds to be made.

page_text: In the foregoing description of our invention we have given one form of
apparatus adapted for carrying the same into effect, but we do not confine ourselves
to the exact arrangements so described and illustrated as the same may be varied,
so long as the essential features of our invention be retained, that is to say the
employment of means for effecting the removal of the pattern or core into and out
of the mould box by mechanical means without causing disturbance of the mould
box or mould as herein explained.
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. The construction, combination or arrangement and use in the manufacture of
moulds for use in the casting of metals for ingots of steel or other metal, of means
or apparatus whereby the removal of the pattern or core into and out of the
moulding box can be effected by mechanical means without disturbing the moulding
box or mould substantially as set forth.
2. The hereinbefore described arrangement or combination of parts forming
mechanical means for effecting the operation of the pattern or core in apparatus for
use in casting ingots of steel or other metals.
