IMPROVEMENTS IN CONSTRUCTING FOUNDERS' LADLES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, CHARLES MONEIL, Junior, of 270 West Scotland Street, Kinning Park, in the
County of Renfrew, Forge Master, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN CONSTRUCTING FOUNDERS' LADLES" to be as
follows:-
My said Invention has for its object the construction of founders' ladles in an
improved manner and so as to be lighter and less liable to fracture than ordinary
ladles; and the Invention consists in making the ladles out of plates or sheets of
mild steel or of wrought iron of good quality by what may be termed a compound
stamping process.
In carrying out the Invention in the case for example of a ladle for holding,
about owts of molten metal, a circular steel plate is taken of about 16 inches in
diameter and about inch thick, and after being suitably heated is compressed
between a first pair of castiron or steel dies shaped to impart a small change of
form to the plate. The plate is similarly compressed between seven different pairs
of dies of graduated shapes in succession being heated prior to each compression if
necessary. The dies are compressed by preference by means of an hydraulic or
other press; or a steam or other hammer. If a single press is used and the dies
have to be changed the heating may require to be repeated prior to each successive
compression but if two or more machines are used so that the plate can be
transferred quickly from one pair of dies to the next the plate will require to be
heated fewer times. After the plate has been brought to the required tinal shape
the handles may be fixed on in the ordinary way; or when the handles are formed
with a ring to encircle the ladle the last pair of dies may be shaped so as to fix the
ring of the handles in an indentation in the sides of the ladle. With ladles of
different sizes and forms, different numbers of graduated pairs of dies may be
required. A further minor improvement consists in forming small corrugations on
the internal surface by suitably shaping the dies, for the purpose of retaining the
lining in an improved manner.

page_text: I, CHARLES MŰNEIL, Junior, of 270 West Scotland Street, Kinning Park, in the
County of Renfrew, Forge Master, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN CONSTRUCTING FOUNDERS' LADLES" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement that is to say :-
:-
My said Invention has for its object the construction of founders' ladles in an
improved manner and so as to be lighter and less liable to fracture than ordinary
ladles; and the Invention consists in making the ladles out of plates or sheets of
mild steel or of wrought iron of good quality by what may be termed a compound
stamping process.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to.
Figures, 1 to 7, being sections representing a steel plate as being compressed
between seven different pairs of dies of graduated shapes, and figure, 8, represents
the ladle in a finished state and ready for the handles to be fixed on. In these
drawings the same reference letters are used to mark the same or like parts
wherever they are repeated.
In carrying out the Invention in the case for example of a ladle for holding
about cwts. of molten meltal, a circular steel plate, A, is taken of about 16 inches
in diameter and about inch thick, and after being suitably heated is compressed
between a first pair of castiron or steel dies, B, (figure 1) which impart a small
change of form to the plate. The plate, A, is then transferred by any suitable
means to the second pair of dies, B, shown in figure, 2, which impart a further
small change of form to the plate, A. The plate, A, being then transferred in
succession to the dies, B, shown in figures, 3, 4, 5, 6, and 7, and acted on in each of
the pairs of dies, B, in a similar manner.
The number of successive operations to which the plate, A, ought to be subjected
will vary according to the thickness of the plate employed or the size or form of
the ladle desired. After passing through these successive operations the plate, A,
will assume the form shown in figure, 8, which represents the ladle in a finished
state and as ready for the handles to be fixed on.
The dies, B, are compressed by preference by means of an hydraulic or other
press or a steam or other hammer. If a single press is used and the dies, B, have
to be changed the heating may require to be repeated prior to each successive
compression but if two or more machines are used so that the plate, A, can be
transferred quickly from one pair of dies, B, to the next the plate, A, will require
to be heated fewer times. After the plate, A, has been brought to the required
final shape the handles may be fixed on in the ordinary way: or when the handles
are formed with a ring to encircle the ladle the last pair of dies may be shaped so
as to fix the ring of the handles in an indentation in the sides of the ladle.
A further minor improvement consists in forming small corrugations on the internal
surface by suitably shaping the dies, for the purpose of retaining the lining in an
improved manner.
I do not restrict myself to the precise details herein described or delineated
provided that the distinctive feature of my Invention is retained; this being; the
formation or construction of founders' ladles by pressing plates or sheets of mild
steel or wrought iron between a series of pairs of dies of graduated forms and sizes.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
The formation or construction of founders' ladles by pressing plates or sheets of
mild steel or wrought iron between a series of pairs of dies of graduated forms and
sizes substantially as hereinbefore described.
