Complete Specification Accepted, 10th Aug., 1888
1, GEORGE ALEXANDER DICK, of No. 110, Cannon Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
It is well known that the lower grades of yellow metal which contain about
60 per cent. of copper, and about 40 per cent. of spelter can be forged at a red heat
under the hammer, and my present invention consists first, in stamping, that is to
say, in squeezing or forcing blocks or bars of such metal in a heated state into steel
or iron dies either by gradual pressure or by a blow, and this invention further
consists in substituting for from 0.1 to 8 per cent. of the copper contained in such
metal a corresponding quantity of iron, manganese and aluminium or an equivalent
proportion of any of such metals or of any mixture or compound of the whole or any
of the same, for the purpose of improving the nature of such alloys for the production
of stampings, as when at a red heat the said improved alloys are extremely malleable
and with a comparatively light blow or low pressure are readily caused to fill the
hollows and crevices of the dies, even when the same are very small and fine.
Dated this Sixteenth day of January 1888.

page_text: I, GEORGE ALEXANDER DICK, of No. 110, Cannon Street, in the City of London,
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:—
It is well known that the lower grades of compounds or alloys of copper and
spelter which contain about 60 per cent. of copper and about 40 per cent. of spelter
can be forged at a red heat under the hammer and my present invention consists in
stamping, that is to say, in squeezing or forcing, blocks or bars of such metal, when
alloyed as hereinafter described, in a heated state, into steel or iron dies either by
gradual pressure or by a blow. The nature of the said metal is rendered especially
suitable for such operation by substituting for from 0.1 to 8 per cent. of the copper
contained in the above mentioned compound of copper and spelter, a corresponding
quantity by weight of a metal compound consisting of iron, manganese and
aluminium, in any relative proportions, for example. The metals may be conveniently
mixed by melting copper then adding manganese, then adding iron in combination
with the zine and lastly adding aluminium. Other modes of effecting the mixture of
the metals, may be adapted, and, in some cases, the iron or the manganese may be
omitted. When the improved metallic compound is to be employed for bearing
.surfaces, I prefer to employ equal quantities of iron, manganese and aluminium, for
fuses I may employ 3 parts of iron or manganese to part of aluminium, and for
connecting rods and toothed wheels, I find the compound or alloy is greatly improved
by adding the said metals in the following proportions, 2 parts of manganese, 2 parts
of iron and part of aluminium.
The above metallic compound of copper spelter, aluminium and manganese, with
or without the addition of iron, I find to be especially useful in the manufacture of
stamped articles such as toothed wheels, connecting rods, fuses for shells and other
articles where alloys of copper are commonly employed.
My said improved metallic compounds are extremely malleable and with a
comparatively light blow or low pressure are readily caused to fill the hollows and
crevices of the dies, even when the same are very small and fine.
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 :-
First. The manufacture of articles made by a stamping or equivalent operation
from the improved metallic compounds hereinbefore described.
And Secondly. The use in the manufacture of stamped articles of the improved
metallic compounds formed as herein before described.
