PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Casting Molten Metal, Slag, and
other 'Molten Material into Pigs, Blocks, or other like Forms.
WO THOMAS HYDES. Havelock Square Sheffield in the County of York, Engineer,
and SYDNEY WILLIAM WILKINSON, Nottingham Street Sheffield aforesaid, Engineer,
do hereby declare the nature of this invention to be follows:-
This invention relates to improvements in the apparatus for and method of casting
automatically and continuously, molten metal, slag, and other molten material run
direct from the furnace into pigs, blocks, slabs and other like forms for various
purposes for which such materials are required.
In carrying our invention into practico we propose to construct a cylinder of
considerable diameter, preferably enclosed at each end, and provided with an axle, or
trunnions upon which it can be revolved by suitable gearing.
On the face or periphery of the cylinder we construct a number of recessed moulds
of any desired shape and size, extending completely round the cylinder; the face, or
top edge of the metal which forms the division walls between and round the recesses
or moulds is made true and circular, and the interior of the cylinder is prepared.to
receive and retain or hold water or steam.
On one side of the cylinder we fix a large hollow or partly hollow, frame of metal,
its front side being made concave to correspond with and fit closely against the
recessed periphery of the cylinder, and reaching for example about one third round
the circumference of the cylinder.
The top of this metal frame we propose to construct somewhat like a hopper to
receive the molten metal or slag as it runs from the furnace, one side of the hopper or
receiver being formed by the periphery of the cylinder, which is caused to revolve
towards the metal frame, and at the lower part of the metal frame we propose to fix a
shoot or conductor to carry away the pigs, blocks or slabs when they drop from their
respective moulds.
An elevator may be used in conjunction with the shoot or conductor, to carry
forward the products to the desired place.
When therefore the cylinder is revolving, and molten metal is run into the hopper,
the recesses or moulds are at once filled, and are closed by being passed against the
concave face of the metal frame, becoming cooled as they pass round, and when
relieved at the bottom position they fall out onto the shoot and are carried away.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Casting Molten Metal, Slag, and
other Molten Material into Pigs, Blocks, or other like Forms.
We, THOMAS HYDES, Havelock Square, Sheffield, in the County of York, Engineer,
and SYDNEY WILLIAM WILKINSON, Nottingham Street Sheffield aforesaid Engineer,
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:
This invention relates to improvements in the apparatus for carrying out a method
of casting automatically and continuously, molten metal, molten slag, or other molien
material, running direct from the furnace, into pigs, blocks, slabs, or other like forms,
for various purposes for which such materials may be required.

page_text: The annexed sheet of drawings illustrates our invention; like letters indicate like
parts in either of the two figures.
Fig. 1 is a plan of an apparatus made according to our invention.
Fig. 2 is an elevation of same.
In carrying our invention into practice we construct a cylinder A, of considerable
diameter, preferably enclosed at each end by an end plate B, so as to make the
interior watertight, and we provide it with a central axis or trunnions, resting in the
bearings C, upon which it can be revolved by the use of suitable gearing, such as
the wheel D, pinion E, cross shaft F, and pulleys G.
In the face or periphery of the cylinder Ä, we construct a number of recessed
moulds H, of any desired shape and size, extending completely across the face in one
recess for pigs, or in a series of short recesses for blocks; they are carried round the
whole circumference of the cylinder.
The top edge or face of the division wall between and round the ends of the recesses
is made true and circular, and the interior of the cylinder is prepared to receive and
to retain water or steam.
On one side of the cylinder we fix a large frame of metal I, made hollow (or partly
hollow) so as to contain water; its front side is made concave to correspond with the
outline and to fit closely against the recessed periphery of the cylinder A, reaching
for example about one third round the circumferential face of the cylinder.
The top of this metal frame I, we propose to construct with sides J, so as to form a
hopper, to receive the molten metal, or slag K as it runs from the furnace; the
cylinder is caused to revolve towards the metal frame I, in the direction of the arrow,
and at the bottom of the said frame we fix a shoot or inclined conductor L, down
which the pigs or slabs slide, when they drop by gravitation from the cylinder.
We may use an elevator M, in conjunction with the conductor L to carry away the
pigs or slabs N to the trucks or other means of removal.
It will therefore be understood that when the cylinder is revolving, and molten
metal is run into the hopper as shown in Fig. 2, the open moulds H, are at once
filled, and are closed by being passed under and against the concave face of the metal
frame I, and as they pass round become cooled, and eventually as they pass the bottom
end of the metal frame, they drop out of the moulds, slide down the incline, and are
carried away.
Although we prefer the use of water admitted into the interior of the cylinder, we
do not bind ourselves to such use, as in some cases it is not necessary to do so.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same may be performed, we declare that what we
claim is :-
1-The improved apparatus for casting molten metal, slag, or other molten material,
consisting of a cylinder having the moulds formed round its circumferential surface,
and caused to revolve by any suitable means, in combination with a partly encircling
metal frame for retaining and cooling the castings until they reach the lowest position
where they drop from the cylinder, substantially as herein before described and shown.
2-Casting pigs of metal or slabs or blocks of slag in moulds formed in the circum-
ferential face of a cylinder, while it is revolving, in the manner substantially as
hereinhofora described and as illustrated.
