Definitions
- This invention relates to an alloy to be used as asubstitute for platinum, in jewelry and elsewhere, and the objects of the invention are to secure such an alloy which shall closely simulate the color of platinum and which can be worked in substantially the same manner as platinum; to obtain such an alloy which can be satisfactorily machined or operated upon with tools, and which will not tarnish readily, and to obtain other advantages and results as may be brought out in the following description.

PATENT OFFICE.
FREDERIC E. CARTER, OF NEWARK, NEW JERSEY, ASSIGN'OR TO BAKER & COMPANY,
INC., A. CORPORATION. OF NEW JERSEY.
ALLOY.
No Drawing.
T 0 all whom it may concern:
Be it ,known that I, F REDERIO EDWARD CARTER, a subject of Great Britain, and a resident of Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Alloys, of which the following is a specification.
This invention relates to an alloy to be used as asubstitute for platinum, in jewelry and elsewhere, and the objects of the invention are to secure such an alloy which shall closely simulate the color of platinum and which can be worked in substantially the same manner as platinum; to obtain such an alloy which can be satisfactorily machined or operated upon with tools, and which will not tarnish readily, and to obtain other advantages and results as may be brought out in the following description.
In carrying out my invention I employ gold and nickel in substantially the propor tion 83.3% gold and 16.7% of nickel, which gives an alloy of twenty carats fineness. This alloy can be satisfactorily worked by jewelers who have been accustomed to working platinum, and gives a color to the finished articles which is so close to the color of platinum that it can scarcely be distin guished from it. Furthermore, the alloy is of a high degree of fineness, and takes a polish or finish which does not readily tarnish. Also, it is made from only two metals,

so that there are few complications of qualit1es to deal with in producing it uniformly,
and it possesses many valuable and .advanlimits as -would not materially affect the color; that is, a little more gold might be used in proportion to the nickel, in case one Wanted the alloy softer and more workable, and on the other hand a little less gold might be used in proportion to the nickel, but the alloy would become harder and more difficult to work. The limits within which the proportions might vary are only two or three per cent. in either direction, say from 80% to 85% of gold, which would vary the alloy from 19.2 carats to 20.4 carats fineness.
Having thus described the invention, what I claim is:
An alloy containing gold and nickel in substantially the proportions of 83.3% of gold and 16.7% of nickel, simulating the color of platinum and capable of being worked substantially as platinum.
FREDERIO E. CARTER.
