PROVISIONAL SPECIFICATION.
Manufacture or Production of Metallic Alloys.
I PERCEVAL MOSES PARSONS of Melbourne House, Blackheath, in the County of
Kent Civil Engineer, do hereby declare the nature of this invention to be as follows:-
My Invention consists in the manufacture or production of certain Alloys especially
intended to be added to copper or copper alloys.
These alloys are composed of Iron, Tin and Aluminium or of Ferro-Manganese and
Tin with or without Aluminium, or of Ferro-Manganese, Iron and Tin with or with
out Aluminium.
These metals I melt together in a crucible or other convenient appliance and when
they are thoroughly combined the resulting alloy may at once be mixed with the
copper or copper alloy, melted ready to receive it, or it may be cast into ingots for
future use to be remelted and mixed with the copper, or copper alloy, as required.
Dated this 4th day of January 1889.
COMPLETE SPECIFICATION.
Manufacture or Production of Metallic Alloys.
I PERCEVAL MOSES PARSONS of Melbourne House Blackheath in the County of
Kent Civil Engineer 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 consists in the manufacture or production of certain alloys especially
intended to be added to copper or copper alloys but I do not limit myself to their
use for that particular purpose.
These alloys are composed according to this Invention of iron, tin and aluminium
or of ferro-manganese and tin with, or without aluminium or of ferro-manganese,
iron and tin with or without aluminium.

but these proportions may be varied according to the quality of the alloy it is required
to produce. I have given the proportions for iron, tin, manganese, and aluminium
together.
In cases where all these materials are not employed I omit those not to be used
and the proportions of the others may remain as above.
The metals I melt together in a crucible or in other convenient appliance and
when they are thoroughly combined the resulting alloy may at once be added to
melted copper or copper alloy with which it is to be incorporated or the said alloy
may when made be cast into ingots for future use to be remelted as desired and
mixed with the copper or copper alloy or be otherwise employed as required. When
an alloy according to this invention is to be added to a copper alloy more especially
alloys of composed of, or principally of copper and zinc, or copper and tin or of
copper and zinc and tin the said alloys made according to this Invention may be first
mixed with the melted copper and the zinc or tin or both be afterwards added.

page_text: When the said alloys according to this Invention are added to gun metal alloys
(that is alloys composed of copper and tin) or to Bronze alloys (that is alloys composed
of copper tin and zinc). in which the tin is equal to, or in excess of the zinc; the
quantity of tin in the said alloys according to this Invention may be the higher
quantity hereinbefore given, or even still higher, as generally more tin will be
required in the gun metal or bronze alloys than the quantity contained in the said
alloys produced according to this Invention.
When added to the brass or yellow metal alloys the tin should be within the
proportions hereinbefore given unless it is required to make a very hard brittle copper
alloy.
The manganese for the gun metal or bronze alloys should generally be more than for
the brass or yellow metal alloys as explained and to combine the various proportions
of manganese in the said alloys-ferro-manganese containing a known high percentage
of manganese may be used together with the requisite quantity of iron (by preference
wrought iron scrap) so as to adjust the iron and manganese in the alloy to the
proportions required.
As regards the aluminium the smallest quantity given hereinbefore has an
appreciable effect in preventing oxidation and rendering the copper alloys (especially
the brass or yellow metal alloys) more fluid and as the quantity is increased it
improves their strength and hardness.
in adding any of the before nained alloys to the copper or copper alloys it will be
found best to melt the copper and bring it to a boiling heat and at the same time to
melt the said alloy in a separate furnace and when liquid pour it quickly into the
melted copper and thoroughly incorporate them by stirring.
The quantity of the said alloys to be used with the copper alloys will vary according
to qualities required in the copper alloys so treated. From one to five parts of the
said alloy for every 100 parts by weight of the copper alloys will generally be
sufficient bearing in mind that as the quantity of the said alloys is increased the
strength and hardness of the resultant alloy increases but its ductility diminishes.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The manufacture and production of metallic alloys consisting of iron tin and
aluminium or of ferro-manganese and tin with or without aluminium or of ferro-
manganese iron and tin with or without aluminium.
2. The manufacture and production of metallic alloys by the incorporation of either
of the alloys claimed by the preceding claiming clause with copper or with copper
alloys.
