Definitions
- the subject-matter of the present application is a metal alloy which is particularly well adapted for use in bearings.
- the White metals or antifriction metals commonly used it has the advantage that it can be very easily worked and in particular very readily turned, that when being cast it fills the mold more perfectly than said hitherto-known metals, that it is relatively very hard, and, first and foremost, that it possesses an extremely small coefficient of friction.
- This new alloy is obtained by melting together approximately equal parts of cadmium and zinc with the addition of antimony to the extent of a few per cent.
- the alloy may, for example, consist of forty-five to fifty parts cadmium, forty-five to fifty parts zinc, and up to tenparts antimony.

UNITED STATES PATENT OFFICE.
HANS KREUSLER, OF WILMERSDORF,GERMANY, ASSIGNOR TO SIEMENS r. HALSKE AKTIENGESELLSGHAFT, OF BERLIN, GERMANY.
ALLOY FOR BEARINGS.
Specification of Letters Patent.
Patented Sept. 18, 1906.
Application filed May 16,1906. Serial No. 317,216.
To all whom it may concern:
Be it known that I, HANS KREUSLER, chemist, a subject of the German Emperor, residing at Wilmersdorf, near Berlin, Germany, have invented a certain new and useful Improvement in Alloys for Bearings, of which the following is a full, clear, concise, and exact description.
The subject-matter of the present application is a metal alloy which is particularly well adapted for use in bearings. As compared with the White metals or antifriction metals commonly used it has the advantage that it can be very easily worked and in particular very readily turned, that when being cast it fills the mold more perfectly than said hitherto-known metals, that it is relatively very hard, and, first and foremost, that it possesses an extremely small coefficient of friction.
This new alloy is obtained by melting together approximately equal parts of cadmium and zinc with the addition of antimony to the extent of a few per cent. The alloy may, for example, consist of forty-five to fifty parts cadmium, forty-five to fifty parts zinc, and up to tenparts antimony.
It is preferable not to employ more than ten per cent. of antimony, as if more than 0 this amount be used the alloy becomes too brittle. An admixture of five per cent. anti-- mony gives very good results. If the ratiu of cadmium to zinc be considerably alterer v the coefficient of friction is increased and th; other good qualities of the alloy are also ma teria-lly detrimentally affected.
What I claim as my invention, and desirto secure by Letters Patent, is
1. An alloy for bearings and the-like, con
sisting of approximately equal parts of cada mium and zinc and a small admixture of antimony.
2. An alloy for bearings and the like, corn sisting of approximately equal parts of cadmium and zinc and less than ten per cent.
antimony.
3. An alloy for bearings and the like, con sisting of approximately equal parts of cadmium and zinc and five per cent. antimony.
4. An alloy for bearings and the like, con-
