UNITED STATES PATENT OFFICE.
ARTHUR E. HOBSON, OF MERIDEN, CONNECTICUT, ASSIGNOR TO INTER- NATIONAL SILVER CO., A CORPORATION OF NEW JERSEY.
METAL ALLOY.
Specification of Letters Patent.
Patented March 12,1907.
Application filed March 22, 1906. Serial No- 307,383-
To all whom. it may concern):
I Be it known that I, ARTHUR E. HoBsoN, a
Meriden, in the county of New Haven and State of Connecticut, have invented a-newand Improved Metal Alloy, of which the following is a specification.
My invention relates more especially to that class of manufactured metals known as German silver or nickel-silver, that is tain proportions; and the object of my invention is to rovide an alloy includin the above-mentioned'metals that may be eely worked and spun without liability of firemetal t at shall have a fine a pearanceand that shall be extremely durable.
It is of course well known that German silver is produced by combining copper, zinc, andnickel; but extreme care must be taken 1 in the working of such a'metal in order to l revent fire-cracking. Various means have eretofore been employed for the purpose of attaining this. result, and I am aware that manganese has been introduced into the composition. :These efforts, however, have proven unsuccessful for the reason that too great a quantity of manganese has been eml A metal for producing good results should not contain manganese in excess of four per cent. of the entire amount nor zinc in excess of twenty per cent. of the entire amount. The nickel and copper may vary, it beingun- (lerstood, however, that a relatively high proportion of copper is usually employed.
I have demonstrated that good results may be obtained from a composition as follows: copper, sixty-seven per cent; zinc, twenty per cent; nickel, ten per cent; manganese, three per cent. I have also obtained good results in a composition composed of copper, fifty-nine per cent; zinc, twenty per cent; nickel, eighteen per cent; manganese, three per cent.
From the above it willfappear that the rel-- ative proportions of the zinc and manganese are retained, and even these may be varied to some extent so long as the proportion of the manganese does not exceed four er cent. and that of the zinc does not excee twenty per cent. of the entire composition.
What I claim as my invention, and desire to secure by Letters Patent, is
1. An alloy composed of copper, nickel, zinc and manganese, the latter to be not more than four per cent. of the whole.
2. An alloy composed of copper, zinc,
ployed and also for the further reason that nickel and manganese, the manganese to be the proper proportions of the other metals not more than four per cent. and the zinc to entering into the composition have not been l be not more than twenty per cent. of the em loyed. 1 whole.
y extended experiments I have demon- 3. An alloy composed of copper, zinc, strated that manganese when employed in a I nickel and manganese, the manganese to be proper pro ortidn to the other metals, the E not more than four per cent, the nickel not other meta s also being employed in certain more than eighteen per cent, and the zinc definite portions not heretofore known, that the man anese greatly improves the result- F ant meta and the latter'can be easilyworked and spun with little liability of fire-cracking.
In extending my experiments I finally deml onstrated the fact that a very small proportion of manganese must be employed and that the proportion of zinc must be reduced from that heretofore employed.
