PROVISIONAL SPECIFICATION.
Improvements in the Manufacture and Production of Alloys of
Copper and Manganese.
We, JOHN BROCK of Wellfield, Widnes in the County of Lancaster, Alkali
Manufacturer and JOHN FENWICK ALLEN of 147 Withington Road Manchester
in the County of Lancaster, Chemist and Metallurgist do hereby declare the nature
of our invention to be as follows: :-
The object of this invention is to obtain in a ready and efficient manner from
ferro-manganese and metallic copper, alloys of copper and manganese the process
being capable of being so conducted that the alloys can be obtained free from iron.
The ferro-manganese and metallic copper are melted together in crucibles or
furnaces and with suitable fluxes, such for instance as carbonate of soda, borax and
common salt. The proportions of these fluxes may advantageously be about
10 per cent. of carbonate of soda and 5 per cent. of borax and common salt. If the
temperature be regulated so that the manganese alloys fuse, the iron remaining
in an unfused scoria and about one part (by weight) of ferro-manganese and
3 parts (by weight) of metallic copper be used the alloys can be obtained free
from iron.

Improvements in the Manufacture and Production of Alioys of
Copper and Manganese.
We JOHN BROCK of Wellfield, Widnes in the County of Lancaster Alkali
Manufacturer and JOHN FENWICK ALLEN of 147 Withington Road, Manchester
in the County of Lancaster Chemist and Metallurgist 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:-
The object of this invention is to obtain, in a ready and efficient manner, from
ferro-manganese and metallic copper, alloys of copper and manganese, the process
being capable of being so conducted that the alloys can be obtained free, or
practically free, from iron. The ferro-manganese and metallic copper (preferably
in a finely divided condition) are melted together in crucibles or furnaces and with
suitable fluxes, such, for instance, as carbonate of soda, borax, and common salt.
For example in carrying this invention into practice, we place in a crucible about
three parts by weight of metallic copper and one part by weight of ferro-
manganese, together with the necessary amount of fluxes, which may advan-
tageously be about 10 per cent. of carbonate of soda, and five per cent. of borax and
common salt.
If the temperature, during the fusion, be suitably regulated the manganese
copper alloy may be obtained fused, and practically free from iron, which remains
in an infused scoria.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is: :-
1. In the manufacture and production of alloys of copper and manganese the use
of ferro-manganese in conjunction with metallic copper and fluxes substantially as
hereinbefore described.
2. In the manufacture and production of alloys of copper and manganese the use
of ferro-manganese in conjunction with metallic copper and fluxes, in about the
proportions substantially as herein before described.
