I, WILHELM BECKER, of Germania-Hütte, near Grevenbrück, Westphalia, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method and means of producing cast metal
ingots of small cross section (say from 50 to 90 millimetres □) suitable for the
manufacture of wire, light sections, thin sheets and the like.
The invention has for objects to produce ingots of great density at their outer parts
and also to reduce, as much as possible, loss such as has been usual with methods
heretofore adopted owing to waste in the runners and gates.
I arrange under the moulds at right angles to a longitudinal channel, a second or
transverse channel surrounded by a frame, this channel being formed in refractory
material either moulded in the frame or otherwise inserted as a lining. The said
transverse channel is placed in communication by means of suitable openings at the
top with the moulds and at the bottom with the longitudinal channel in such a
manner that a large number of ingots can be cast from one funnel.
In order to a more clear understanding of the nature of the invention an arrange-
ment of apparatus suitable for carrying it into effect is illustrated by way of example
in the annexed sheet of drawings in which Fig. 1 is a longitudinal vertical section;
Fig. 2 a transverse section; Fig. 2 a plan or top view of ingot moulds; Fig. 3 a
plan or top view of part of a base plate, frames and ingot moulds; and Figs. 4, 5
and 6 are detail views.
a is a base plate (Figs. 3 and 4) of square or rectangular form in plan, provided
with a central channel that extends from one end of the plate to the other, and is open
at the top. The channel is lined with refractory material in such a manner as to form
at or near its centre, a cylindrical channel c (Fig. 1), having at its top a number of
openings d, d, d, the distance apart of which is dependent upon the size of the ingot
moulds. e, e are frames shewn in plan or top view, and in transverse section
respectively, in Figs. 5 and 6. They are each provided with a central longitudinal
channel of refractory material which is formed at the bottom with an opening and
at the top with a number of openings i, for example as shown in Figs. 2, 5 and 6.

page_text: The frames e are arranged crosswise of and upon the base plate a, so that the
openings in the former correspond with the openings d in the latter and thus
establish communication between the channels c and f. The channels are situated
transversely to the channel e as shown in the drawing.
Upon each frame e are placed the ingot moulds C of which, as shown in Figs. 2
and 2, several, say 6, may be formed together. Each of the openings ii corresponds
to an ingot mould, so that the channel c is placed in communication with each ingot
mould.
At the centre of the base plate a is arranged a pipe T provided with a funnel T
into which molten metal can be poured; from this pipe the metal passes into the
channels e and fand thence into the moulds C, 0, 0, until they are filled.
с
With the apparatus shown by way of example in the drawing, seventy two ingots
can be cast from one funnel.
The moulds must be well heated before casting, in order to obviate a too speedy
cooling of the metal.
This can be easily done in the case of this improved apparatus, by simply con-
necting the funnel T¹ by a flange to a blast pipe and then driving hot air through
the channels or moulds."

page_text: Improvements in or Pertaining to the Casting of Metal Ingots.
I WILHELM BECKER, of Germania-Hutte, near Grevenbruck, Westphalia 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 an improved method and means of producing cast metal
ingots of small cross section (say from 50 to 90 millimetres) suitable for the manu-
facture of wire light sections thin sheets and the like.
The invention has for objects to produce ingots of great density at their outer parts
and also to reduce as much as possible loss such as has been usual with methods here-
tofore adopted owing to waste in the runners and gates.
I arrange under the moulds 'at right angles to a longitudinal channel as second or
transverse channel surrounded by a frame this channel being either formed in
refractory material moulded in the frame or otherwise inserted as lining. The said
transverse channel is placed in communication by means of suitable openings at the
top with the moulds and at the bottom with the longitudinal channel in such a manner
that a large number of ingots can be cast from one funnel.
An arrangement of apparatus suitable for carrying my invention out in practice is
shewn in the annexed drawings in which
Figure 1 is a longitudinal vertical section,
Figure 2 a transverse section; figure 2ª a plan or top view of ingot moulds.
Figure 3 is a plan or top view of part of a base plate frames and ingot
moulds and
Figures 4. 5 and 6 are detail views.
A is a base plate (Figures 3 and 4) of square or rectangular form in plan provided
with a central channel & that extends from one end of the plate to the other and is
open at the top.
The channel is lined with refractory material in such a manner as to form at or
near its centre a cylindrical channel c (Figure 1) having at its top a number of
openings d d d the distance apart of which is dependent upon the size of the
ingot moulds.
ee are frames shewn in plan or top view and in transverse sections
respectively in figures 5 and 6..
They are each provided with a central longitudinal channel f of refractory materia!
which is formed at the bottom with an opening and at the top with a number of
openings i for example as shewn in Figures 2. 5 and 6.
The frames e are arranged crosswise of and upon the base plate a so that the
openings in the former correspond with the openings d in the latter and thus
establish communication between the channels c and f.
The channels are situated transversely to the channel c as shewn in the drawing.
Upon each frame e are placed the ingot moulds C of which as shown in Figures 2
and 2ª several say six may be formed together.

page_text: Each of the openings i. i corresponds to an ingot mould so that the channel c is
placed in communication with each ingot mould.
At the centre of the base plate a is arranged a pipe T provided with a funnel T
into which molten metal can be poured; from this pipe the metal passes into the
channels cand fand thence into the moulds ccc until they are filled.
With the apparatus shewn by way of example in the drawing seventy two ingots
can be cast from one funnel.
The moulds must be well heated before casting in order to obviate too speedy
cooling of the metal.
This can be easily done in the case of this improved apparatus by simply connecting
the funnel T by a flange to a blast pipe and then driving hot air through the channels
or moulds.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare what I
claim is
For producing cast metal ingots of small cross sections suitable for the manu-
facture of wire, light sections thin sheets and the like the arrangement and use
under the ingot moulds CC transversely to the longitudinal channel c of a second
channel surrounded by a frame e such channel being formed in refractory material
either moulded in the frame or otherwise inserted as a lining and placed in communica-
tion by means of suitable openings i at the top with the ingot moulds C C and at
the bottom with the longitudinal channel c of the base plate a in such a manner that a
large number of ingots can be cast from one funnel.
