F Asthöwer and C, of Annen, Westphalia Germany for an Invention of
IMPROVEMENTS IN APPARATUS FOR RUNNING METALS SIMULTANEOUSLY INTO
SEVERAL MOULDS
PROVISIONAL SPECIFICATION left by the said Friedrich Asthöwer at the
Office of the Commissioners of Patenta on the 6th November 1882:
FRIEDRICH ASTHOWER doing business under the firm of F. Asthöwer and Cº
of Annen Westphalia, Germany, "IMPROVEMENTS IN APPARATUS FOR RUNNING
METALS SIMULTANEOUSLY INTO SEVERAL MOULDS
"
This invention relates to an improved apparatus to enable small ingots or
bodies of steel and other metals to be more expeditiously and economically cast
than could heretofore be done:
This apparatus is constructed as follows. On a bed plate are a series of small
projections for supporting the moulds or "chills" in which the steel, &c is to be
cast; in the centre of the bed plate there is a suitable pillar or support carrying a
shallow cylindrical vessel of sheet iron lined with à non combustible material.
Perfofations are so arranged in the vessel and in the fireproof lining as to be
exactly over the centre of the moulds or chills above mentioned. Radial slots or
channels connect the perforations with ä höllow or depression made at the centre
of the vessel in the fireproof lining.
The metal is. poured into the central cavity and passes through the channels to
the perforations and runs into the Goulds below. As there is some distance
between the bottom of the shallow vessel and the top of the moulds, it is easy to
see when the same are nearly full and to stop the flow of the molten metal from
the pot accordingly. The said shallow vessel has handles and by successively
placing it upon a series of pillars surrounded by moulds the charge of the melting
pot can be poured quickly and without waste.

FRIEDRICH ASTHOWER doing business under the firm of F. Asthöwer and Co.,
of Annen Westphalia Germany. "IMPROVEMENTS IN APPARATUS FOR RUNNING
METALS SIMULTANEOUSLY INTO SEVERAL MOULDS.”
This invention relates to an improved apparatus to enable small ingots or bodies
of steel or other metals to be more expeditiously and economically cast than could
heretofore be done
This apparatus is constructed as follows. On a bed plate are a series of small
projections for supporting the moulds or "chills" in which the steel & is to be
cast, in the centre of the bed plate there is a suitable pillar or support carrying a
shallow cylindrical vessel of sheet iron lined with a non-combustible material.
Perforations are so arranged in the vessel and in the fire proof lining as to be
exactly over the centre of the moulds or chills above mentioned. Radial slots or
channels connect. the perforations with a hollow, or depression made at the centre
of the vessel in the fire proof lining.
The metal is poured into the central cavity and passes through the channels to
the perforations and runs into the moulds below. As there is some distance
between the bottom of the shallow vessel and the top of the moulds it is easy to
-see-when-the-same-are-nearly-full-and-to stop the flow of the molten metal from
the pot accordingly. The said shallow vessel has handles and by successively
placing it upon a series of pillars surrounded by moulds the charge of the melting
pot can be poured quickly and without waste.
When in the manufacture of cast steel it is desired to pour a great number of
small blocks of say from 20 to 40 kilogrammos weight, from a Bessemer or a
Siemens Martin charge, the difficulty arises that the operation takes up too much
time and that the steel in the pan ultimately becomes too cold. As a remedy a
.common gate or runner has been employed with which all the "chills" or moulds
are connected, but this process results in considerable waste as the gates also
become filled.
Now this apparatus has been devised for the purpose of obviating these
difficulties.
For casting a number of small blocks say 10 for instance (or more or less)
simultaneously I employ the following apparatus
There is a base-plate A on which the "chills" or moulds B. are arranged in a
circle being set up at points especially marked by projections or indicators a as
represented in the accompanying drawings. In the centre of this plate a standard
or upright C is provided which carries the casting-funnel D common to all
the chills
This funnel consists of a shallow cylindrical vessel of sheet iron lined in a
peculiar manner with refractory material as will presently appear. In the bottom
of the vessel D exactly above the "chills" and in line with their axis, there are
perforations b which pass through the refractory lining also, and radial slots c
connect the same with a central depression E which is provided in the refractory
material.
Into this central hollow E the metal is poured and by the radial slots c is carried
in all directions towards the periphery of the funnel and thence flows by the
apertures 6 into the chills. Care has to be taken that the transverse section of
the slots, and also of all the bottom-apertures shall be as much as possible equal if
an equal filling of all the chills is to be attained.

page_text: As the funnel D does not touch the "chills" B by its bottom but a sufficient
space is left between it and the top run of the "chills" the supply. from the ladle
to the funnel E can be interrupted at the proper moment.
The contents of the funnel are then completely emptied into the "chills" and
the funnel may then be laid hold of by the handles g gi and again placed over the
next group or set of chills and will servo to fill these. This operation is continued
till the ladle is emptied, this being attained in a shorter time than was heretofore
possible and without any waste of steel.
Having now described the nature of my said invention and the method of
performing the same I wish it to be understood that what I claim and desire to
protect under the herein before in part recited Letters Patent is
First In an apparatus for pouring a number of castings simultaneously the base
plate A having projections or indicators upon which are placed the moulds
or chills B and central standard C in combination with the movable
pouring or casting funnel D having a central hollow or depression into
which the metal is poured from which radial passages lead to the apertures
in the bottom substantially as described and shown.
Second-The process of pouring or casting a number of small metal blocks simul-
taneously through one casting funnel which is not directly connected with
the "chills" and which allows the fluid metal, suitably divided by radial
channels, to pass to the chills through apertures in its bottom, the extent to
which the chills are filled being observable through the distance between the
pouring-funnel and the "chills" substantially as described and shown.
In witness whereof I the said Friedrich Asthöwer have hereunto set my
hand and seal this first day of May in the year of Our Lord One thousand
eight hundred and eighty three
