PROVISIONAL SPECIFICATION.
Improvements in Ingots Compounded of Wrought Iron or Wrought
Steel and Cast Steel.
I, THOMAS TURNER, of Beansburn, Kilmarnock, in the County of Ayr, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to ingots compounded of wrought iron or wrought steel
and cast steel, and it has for its object to obviate the occurrence of lines of weak-
ness in the ingots or in the bars or other articles rolled or produced therefrom
which weakness is liable to result from the mode generally adopted of arranging
the iron or steel bars or plates which are incorporated in the compound ingot.
To that end in producing the improved ingot I arrange the iron bars or plates
or. steel bars or plates which are to be incorporated with cast steel in such manner
that they break joint one with another or overlap both in the breadth and thick-
ness of the ingot. The bars or plates are preferably of oblong or rectangular
cross section and may be flat or bent in the direction of their breadth and as
viewed in the section of the ingot they are disposed as if laid or set in uneven
lines alternately or at intervals on their longer sides and on edge, but at such
distances apart as to permit of the free flow of the molten steel which is run in
between them. The spaces between the bars or plates of any layer are thus
covered by the bars of the adjoining layer and no open joints for the cast steel
are left extending in straight lines across the breadth or thickness of the ingot.
When the ingot is formed and subsequently rolled or hammered out the iron
bars or plates or steel bars or plates, as the case may be, which are embedded in
the steel overlap each other in several directions and greater strength results.
The bar may further be perforated in order to allow the molten metal to form ties
between the molten metal on both sides of the bar. An ingot such as described
is capable of being flattened down in either direction the overlapping bars or
hard metal of which would require to be penetrated by any drill or projectile
directed against the ingot which is of special importance in the case of safe and
armour plates. In cases in which it is specially desirable to have no cast steel
in a straight line between the bars or plates in any direction through the ingot
(as for instance in safe plates, armour and other plates) so as to give greater resist-
ance to lamination, I may also bend the bars or plates in the direction of their
length in a curved or zig-zag fashion still disposing them in the cross section of
the ingot in the manner already described as of laid or set in uneven lines- alter-
nately on their longer sides and on edge.

do hereby declare the nature of this invention and in what manner the same is to

statement:
This invention relates to ingots compounded of wrought iron or wrought steel
and cast steel, and it has for its object to obviate the occurrence of lines of weak-
ness in the ingots or in the bars or other articles rolled or produced therefrom
which weakness is liable to result from the mode generally adopted of arranging
the iron or steel bars or plates which are incorporated in the compound ingot.
Figure 1 of the accompanying drawings is an end view of an ingot as con-
structed under one modification of my invention, and Figure 2 a part end view of
another form of construction.
In producing the improved ingot I arrange the iron bars or plates or steel bars
or plates A which are to be incorporated with the cast steel E in such manner
that they break joint one with another or overlap both in the breadth and thick-
ness of the ingot The bars or plates A are preferably of oblong or rectangular
cross section and may be flat, as shown at Fig. 1, or bent, as shown at Fig. 2, in
the direction of their breadth, and as viewed in the section of the ingot they are dis-
posed as if laid or set in uneven lines alternately or at intervals on their longer
sides and on edge, but at such distances apart as to permit of the free flow of the
molten steel which is run in between them. The spaces between the bars or
plates A of any layer are thus covered by the bars A of the adjoining layer and no
open joints for the cast steel are left extending in straight lines across the
breadth or thickness of the ingot. When the ingot is formed and subsequently
rolled or hammered out the iron bars or plates A or steel bars or plates, as the
case may be, which are embedded in the steel B overlap each other in several
directions and greater strength results. The bars A may further be perforated
in order to allow molten metal to form ties between the molten metal on both
sides of the bar A. An ingot such as described is capable of being flattened down
in either direction, the overlapping bars or hard metal A of which would require
to be penetrated by any drill or projectile directed against the ingot which is
of special importance in the case of safe and armour plates. In cases in which it
is specially desirable to have no cast steel in a straight line between the bars or
plates A in any direction through the ingot (as for instance in safe plates, armour
and other plates) so as to give greater resistance to lamination, I may also bend
the bars or plates in the direction of their length in a curved or zig-zag fashion
still disposing them in the cross section of the ingot in the manner already
described as if laid or set in uneven lines alternately on their longer sides and on
edge.
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:-
Improved ingots compounded of wrought iron or wrought steel and cast steel,
substantially in the manner hereinbefore described.
