COMPLETE SPECIFICATION.
Improvements in the Manufacture of Iron and Steel Castings.
I, ALFRED JEPSON of Clare Villa 54 Central Road Withington in the County
of Lancaster Wood Engraver 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 improvements in the manufacture of articles of utility or
ornament from cast iron or cast steel, and the object of my improvements is to
toughen and strengthen iron and steel castings without adding appreciably to the
cost of their production. 1 attain this object by casting iron or steel around a thin
core or foundation of wrought or rolled metal as hereinafter described and as
illustrated in the accompanying sheet of drawings. In these drawings similar
letters refer to similar parts throughout the several views. In applying my
improvements to the manufacture of cast metal articles that according to the uses
to which they may be applied, are required to be of a tougher or stronger nature,
I form a thin wrought or rolled steel or metal core b as represented either in
Figs. 1, 2 or 3 or of any shape that may be required according to the form of
casting to be produced. I perforate this metal core, either in the manner shown
or as may otherwise be preferred. In the production of cast metal articles I
employ a mould of usual description, and place within the openings that are left in
the sand to receive the molten metal a metallic core such as I have herein before
described. The projections c which are formed by perforating the metal core bassist
in retaining said core in position in the sand during the process of casting and thus
permit the metal to flow all around each side of said core and at the same time to
pass through the perforations d, by these means uniting the interior and exterior
portions of the casting so as to form one casting. Fig. 4 represents a pipe Fig. 5
section of a corrugated plate and Fig. 6 a hollow casting, and illustrate samples of
castings with my invention applied.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In the manufacture of articles of utility or ornament from cast iron or cast steel,

page_text: the introduction during the process of manufacture of one or more wrought or
rolled metal cores, between any, each, or all of the inner and outer surfaces, for the
purpose and in the manner substantially as herein before described.
Dated this 24th day of April 1891.

Applicant.
