Complete Specification Accepted, 13th Feb., 1889
We, JAMES SINCLAIR, Fire Engineer, and JOHN PHILLIPS SMITH, Engineer, both
of 114 Cannon Street, in the City of London-do hereby declare the nature of our said
invention to be as follows:-
Our invention relates to the production of metallic compounds or. alloys.
The main feature of our said invention is the utilization, in the production of a
metallic compound or alloy, of the substance, commercially known as hard spelter."
We combine with this substance copper, ordinary spelter or zinc, tin, lead, manganese,
phosphorus or other suitable substances, according to the purpose. for which the metal
or alloy is required.
Another feature of our said invention is the employment of. potassium or a salt of
potassium as a flux or fluxing material in the production of our alloys.
3
We find a mixture of the following ingredients very advantageous for various
purposes, viz. "hard spelter" copper, ordinary spelter or zinc and tin, chloride of
sodium, or potassium or a salt of potassium being used as a fluxing material. In
some instances, we add to these ingredients, manganese, phosphorus, or the like. By
using suitable proportions of the ingredients in this mixture we can produce a metal
or alloy of great tensile strength.
If it is desired to produce a cheap and soft metal or alloy for ornamental or other
castings, we sometimes add lead or substitute this metal for the tin or ordinary spelter
in the mixture above described.
By varying the other ingredients or the proportions thereof or both we produce
various useful metals or alloys for example.
A hard close-grained strong metal for bearings, slide-valves, pumps, plungers and
similar articles.
A homogeneous ductile metal of great tensile strength especially suitable for rolling
and forging into bolts, nuts, fire-box stays, and the like, or for drawing into rods
or tubes.

A non-magnetic metal of great strength for dynamo-electric machines and for
electrical purposes generally.
An extraordinarily tough casting metal for screw-propeller blades of ships, for
piston rings, and other objects in which very great toughness is essential.
A special metal which may be drawn into wire for telephonic and other
purposes.
A cheap metal as above mentioned for ornamental castings, such as staircase-
banisters brackets and other ornamental articles.

COMPLETE SPECIFICATION.
Improvements relating to the Production of Metallic Compounds
or Alloys.
We, JAMES SINCLAIR, Fire Engineer, and JOHN PHILLIPS SMITH, Engineer, both
of 114 Cannon Street, in the City of London 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 :-
"
Our invention relates to the production of improved metallic compounds or alloys,
and the main feature of our said invention consists in the employment, in such
compounds or alloys, of the substance commercially known as "hard spelter.'
Another feature of our said invention is the employment, in the production of our
improved compounds or alloys, of potassium or a salt of potassium as a flux or
fluxing material.
In carrying our said invention into practice, we combine, with the "hard spelter,"
copper, ordinary spelter or zinc, tin, lead, manganese, phosphorus or other suitable
substances, or two or more of such substances, according to the purpose for which the
metallic compound or alloy is required.
We find a mixture of the following ingredients very advantageous for various
purposes, viz. "hard spelter," copper, ordinary spelter or zinc, and tin; chloride of
sodium, or potassium, or a salt of potassium being used as a fluxing material. The
aforesaid metals may be mixed in or about in the following proportions, viz. :-
Copper 50 to 70 per cent., Tinto 1 per cent., Zinc 25 to 40 per cent.,." Hard

page_text: spelter" 5 to 15 per cent. In some instances, we add to these ingredients a small
proportion of manganese, phosphorus or the like. By using suitable proportions of
the ingredients in this mixture, we can produce a metal or alloy of great tensile
strength.
If it is desired to produce a cheap and softer metal or alloy for ornamental or other
castings, we sometimes add lead, or we substitute this metal for the tin or for the
ordinary spelter in the mixture above described.
By our invention, we can produce various metals or alloys, suitable for bearings,
slide-valves, pumps, plungers and similar articles, or for rolling and forging into
bolts, nuts, fire-box stays and the like, or for drawing into rods or tubes, or for the
manufacture of screw-propellers or propeller-blades of ships, piston-rings, and other
objects in which very great toughness is essential.
Or a cheap metal as above mentioned for ornamental castings, such as staircase-
banisters, brackets, and other ornamental articles.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it understood
that we claim :-
First. A metallic compound or alloy consisting of "hard spelter" and other
ingredients, as above specified.
Second. In the production of the said metallic compound or alloy, the use of
potassium or a salt of potassium as a flux or fluxing material, as above specified.
