Improvements relating to the Casting or Moulding of Spoons, Forks,
Knives, and other Articles, and to Apparatus therefor.
I, ARTHUR ALEXANDRE, of 75 Ruc Charlot, Paris, m the Republic of
France, Manufacturer, do hereby declare the nature of this invention to be as
follows
My invention relates to the manufacture of spoons, forks, knives and other
articles and to apparatus therefor. It comprises an improved method of moulding
specially designed for use in the manufacture of articles formed of metal applied
to a metallic armature oi core
This method 18 characterized in principle by the use of the centrifugal force
for casting the covering metal upon the armature or core, it has the result of
endeung the manufacture more rapid and therefore more economic; moreover
the apparatus which I employ for canying my aforesaid method into practice
has the advantage of effecting a better distribution of the metal in the mould by
lenson of the velocity of its projection and the force resulting from the centrifugal
actiou.
Although my method is applicable to various articles moulded under the before.
mentioned conditions I will describe by way of example the manufacture of spoons,
forks, knives and the like
Figure 1 of the accompanying diawing represents a plan of a portion of the
moulding plate or disc employed.
Figure 2 is a vertical section through the axis of the same.
Figure 3 shows the arrangement of the ion armature or core for a spoon.
Figure 4 represents the same armature or core and the mode of placing it in the
mould
My improved moulding apparatus is composed of two superposed plates or
discs a and b constituting each one half of a mould c hollowed out in the radial
direction.
These plates or discs, being connected by suitable means enabling them to be
rapidly sepainted, are mounted so as to receive a rotary movement which may be
produced by any appropriate mechanism
The centre of these connected plates or discs constitutes a casting chamber d
communicating with each of the moulds through an orifice e.
I pierce the iron armatures or cores with a hole g, and the part of the plate or
disc which closes each mould carries either a tenon or a pin which enters the
hole 9 in the said armature or cole.
The armatures thus placed are therefore centered of themselves by the centrifugal
force which at the same time vigorously projects into each mould the cast metal
which is poured into the chambei d
It will be understood that without departing from the scope of my invention
and for casting articles of shorter length I may leave the centre of the plates
or discs solid and make the casting chamber in the form of a circular channel
situated close to the extremities of the plates or discs where the moulds are

I, ARTHUR ALEXANDRE, of 75 Ruo Charlot, Paris, in the Republic of
France, Manufacturer, 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 :-
My invention relates to the manufacture of spoons, forks, knives and other
articles and to apparatus therefor.
The said invention comprises an improved method of moulding specially designed
for use in the manufacture of articles formed of metal applied to a metallic
armature o1 CUTE!
This method is characterized in principles by the use of centrifugal force
for casting the covering metal upon the armature or core, it has the result 'of
rendering the manufacture more rapid; and therefore more economic; moreover
theapparatos which I employ for carrying my aforesaid method to practice has
the advantage of effecting a bettor distribution of the motal in the mould 'by
reason of the velocity of its projection and the force resulting from the centrifugal
action
Althougbuny method is applicable to varions articles moulded under the before-
inentioned conditions I will describe by way of example the manufacture of spoons,
forks, kuives and the like:
Referring to the drawing left with my Provisional Specification
Figure 1 represents a plan of a portion of the moulding plate or disc employed.
Figure 2 as a vertical section through the axis of the same.
Figure 3 shows the arrangement of the iron armature or core for the spoon and
Figure 41epresents the same armature or core and the mode of placing it in the
mould..
My improved moulding apparatus is composed of two superposed plates or
discs a and b constituting each one half of a mould chollowed out in the radial
direction.
These plates or discs, being connected by suitable means enabling them to be
rapidly separated, ate mounted so as to receive a rotary movement which' may be
produced by any appropriate mechanism
The centre of these connected plates or discs constitutos a casting chamber d
communicating with each of the moulds throughian orifice e
I pierce the iron armatures or cores with a hole g, and the part of the plate or
disc which closes each mould carries either a tenon or a pin which enters the hole g
in the said nature or core.
The armatures thus placed are therefore centered of themselves by the centrifugal
force which at the same time vigorously projects into each mould the cast metal
whichis poured into the chamber d.
It will be understood that without departing from the scope of my invention and
for casting articles of shorter length I may leave the centre of the plates or discs
solid and make the casting chamber din the form of a circular channel situated
close to the extremities of the plates or discs where the moulds are.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same 16 to be performed, I declaro that what I
claim 15-
1. An improved method of casting and moulding articles, after the manner of
the closed casting process, fiom nietal, upon an non core or amature; this method

page_text: consisting in principle in the airangement of moulds in a disc composed of two
superposed plates having a central casting chamber and utilizing centrifugal force
for driving the molten metal into the moulds substantially as described.
2 In the manufacture of articles by the closed casting process, in which a
metallic armature or core is used, the application of moulds formed between two
superposed plates with a holding device at the lower plate for retaining the
armature or core in free position to thus follow the impulse of the centrifugal
force, and placed in communication with a ceutral casting chamber by means
of suitable orifices, substantially as hereinbefore described and shown in the
drawing.
