Improvements in and relating to Nickel or Nickel-alloy Castings.
I, JOHN COPE, Chairman of Directors of Benjamin Cope and Sons Limited,
Bloxwich, in the County of Staffordshire, Stirrup Manufacturers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the construction of nickel and nickel-alloy castings and
has for object to materially increase the strength of the same.
The invention consists in inserting within the mould in which the nickel is to
be cast, one or more specially prepared steel or metal cores.
The metal core is notched and bent to the required shape and may be tinned or
coated with any suitable metal previous to its insertion within the mould in order
to ensure its adhesion to the nickel casting. Or in lieu of the above I may arrange
to form an enlargement at each end of the metal core.
The invention is designed chiefly for use in the manufacture of nickel-alloy
cheeks for harness bits, stirrups and stirrup-irons, but it may be employed with
advantage in other nickel castings.
Improvements in and relating to Nickel or Nickel-alloy Castings.
I, JOHN COPE, Chairman of Directors of Benjamin Cope and Sons Limited,
Bloxwich, in the County of Staffordshire, Stirrup Manufacturers, 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 the construction of nickel and nickel-alloy castings and
has for object to materially increase the strength of the same. It is well-known
that such castings as ordinarily made are exceedingly liable to fracture and my
invention has for principle object to remedy this defect.
It consists in inserting within the mould in which the nickel or nickel-alloy is to
be cast, one or more specially prepared steel or other metal cores, in such a manner
that when the casting has been made, the core or cores will be embedded in the
casting and serve to strengthen the same.
The metal of which the core is to be made may be any one suitable and which

page_text: has greater tensile and torsional strengths than the nickel or nickel-alloy of which
the castings themselves are formed.
The metal core may have one or more flats or indents formed upon it or may be
jagged or notched, and shaped or bent to the required form, and it may also be
tinned or otherwise suitably coated prior to its being inserted within the mould
in order to ensure its adhesion to the nickel casting.
Or this metal core may sometimes consist of a separate metal casting in which
case it can be provided with short arms or projections intended to more securely
and firmly embed the core in the casting.
In lieu of forming flats or notching or jagging the core I may form an enlarge
ment at each end or at other portions thereof or positions thereon.
The invention is designed chiefly for the use in the manufacture of nickel-alloy
cheeks and mouth pieces for bridle bits, stirrups and the like but it may be cm-
ployed with advantage in other nickel castings.
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. In nickel or nickel-alloy castings the use of a metal core of greater strength
than the metal or alloy forming the casting and inserted within the mould prior
to the casting of the metal therein, substantially as and for the purposes described.
2. In nickel or nickel-alloy castings, the insertion into the mould as a central
strengthening piece for the casting, of a metal core of greater strength than the
metal forming the casting and suitably shaped or jagged or notched, (or provided
with one or more enlargements) for the purpose of causing the core to embed itself
in the casting, as described.
