"
This invention has for its object an improved manufacture of compound metal
plates, whereby two or more layers or slabs of metal, metallic compound or alloys
are welded together by casting as I will now describe.
Figs. 1 and 2 of the annexed drawing shew respectively a plan and a vertical
section of an arrangement for the welding together by casting of plates consisting
two layers either of the same or of different metals, metallic compounds or alloys
of metals.
A is a casting mould into which is placed loosely a slab B which I will term a
"welding piece," and which is maintained therein by means of wedges. A and B
may consist each of one piece or they may be composed of several pieces. The
mould and welding piece may be made of metal, fire clay or baked sand. This
mould and welding piece stand free or they are secured to a smooth base D made
of metal, fire clay or baked sand (fig. 2).
The process of manufacture is as follows:
One kind of the metals, metallic compounds or alloys of metals to be applied is
first cast into the empty space C. After this cast has set, the welding piece B is
taken out of the mould and the other kind of metal, metallic compound or
alloy of metal to be employed is cast into the space formerly occupied by the
welding-piece B. As the first cast will still be at a red heat or hotter, when the
second description of metal is run in, an effectual welding together of the two
metals metallic compounds or alloys of metals will be obtained.
The plate so manufactured is then lifted out of the mould and may be utilised
either in this state or be further worked by pressing, rolling or cutting. If mora

page_text: than two kinds of metals, metallic compounds or alloys of metals, are employed, a
separate welding piece may be used for each further layer and be removed after
each casting, or the same welding piece may be employed consecutively for the
several castings. In this case the welding piece is put first in the place B (see
figs. 3 and 4); when the space E has been filled up, the welding piece is placed at F
and the space B is filled up; the welding piece is then put in G and the space F
filled up, and lastly the welding piece is entirely removed and the space G is filled
up. When three sorts of metals, metallic compounds or alloys of metals are
employed in casting, the welding piece B may be put in the middle (fig. 5) and the
two empty spaces H. F then filled up, either simultaneously or the one after the
other; after this the welding piece is taken out and the empty space filled up.
This invention can be carried out in various ways, all of which are based upon the
essential character of the process above described and which need therefore no
further description. The cross section of the welding pieces and consequently
also that of the mould and the finished cast plates and the method use of the
welding pieces in executing the process may also vary in various ways as above
indicated. If the mould A is composed of several parts, the process may be carried
out as follows.
The welding piece B is secured first to one half A¹ of the mould to be used
(fig. 6) and the space K is then filled up. When this casting is set, the welding-
piece B is removed and the other half A2 of the mould is put in its place (fig. 7);
the empty space L thus formed is now filled up with the other metal (metallic
compound or alloys of metal) to be used.

page_text: An Improved Manufacture of Compound Metal Plates and
Apparatus or Appliances for that Purpose.
I, CHARLES DENTON ABEL, of N° 28 Southampton Buildings, Chancery Lane
in the County of Middlesex, Consulting Engineer and Patent Agent, 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 has for its object an improved manufacture of compound metal
plates, whereby two or more layers or slabs of metal, metallic compound or alloys
are welded together by casting as I will now describe.
"
Figs. 1 and 2 of the annexed drawing shew respectively a plan and a vertical
section of an arrangement for the welding together by casting of plates consisting
of two layers either of the same or of different metals, metallic compounds or alloys
of metals.
A is a casting mould into which is placed loosely a slab B which I will term a
filling piece" and which is maintained therein by means of wedges. A and B
may consist each of one piece or they may be composed of several pieces. The
mould and filling piece may be made of metal, fire clay or baked sand. This
mould and filling piece stand free, or they are secured to a smooth base D made of
metal, fire clay or baked sand (fig. 2).
The process of manufacture is as follows:-
One kind of metals, metallic compounds or alloys of metals to be applied is
first cast into the empty space C. After this cast has set, the filling piece B is
taken out of the mould and the other kind of metal, metallic compound or alloy
of metal to be employed is cast into the space formerly occupied by the filling
piece B. As the first cast will still be at a red heat, or hotter, when the second
description of metal is run in, an effectual welding together of the two metals,
metallic compounds or alloys of metals will be obtained.
The plate so manufactured is then lifted out of the mould and may be utilised
either in this state or be further worked by pressing, rolling or cutting. If more
than two kinds of metals, metallic compounds or alloys of metals are employed, a
separate filling piece may be used for each further layer and be removed after
each casting or the same filling piece may be employed consecutively for the
several castings. In this case the filling piece is put first in the place B (see
figs. 3 and 4); when the space E has been filled up the filling piece is placed at F
and the space B is filled up, the filling piece is then put in G and the space F is
filled up, and lastly the filling piece is entirely removed and the space G is filled
up. When three sorts of metals, metallic compounds or alloys of metals are
employed in casting, the filling piece may be put in the middle (fig. 5) and the
two empty spaces H J then filled up, either simultaneously or the one after the
other; after this the filling piece is taken out and the empty space filled up.
This invention can be carried on in various ways all of which are based upon the
essential character of the process above described and which need therefore no
further description. The cross section of the filling pieces and consequently also

page_text: that of the mould and the finished cast plates, and the method of making use of
the filling pieces in executing the process may also vary in various ways as above
indicated. If the mould A is composed of several parts, the process may be carried
out as follows:
The filling piece B is secured first to one half A¹ of the mould to be used (see
fig. 6) and the space K is then filled up. When this casting is set, the filling
piece B is removed and the other half A³ of the mould is put in its place (fig. 7)
the empty space L thus formed is now filled up with the other metal, (metallic
compound or alloys of metal) to be used.
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
1. The berein described improved method of manufacturing compound metal
plates wherein two or more layers of metal are united together by casting in a
nould by first casting one such layer while the place of the other layer or layers is
occupied by one or more filling pieces, which is or are then removed or shifted so
as to allow of the casting of the other layer or layers.
2. The use in the manufacture of compound metal plates referred to in the
preceding claim, of filling pieces of any desired configuration, and consisting of one
or, more parts, operating in combination with moulds, substantially as herein
described.
