Description

Patented Oct. 19, 1948 UNITED STATES PATENT OFFICE BEARING ALLOY British company No Drawing. Application June 20, 1944, Serial No. 541,279. In Great Britain April 2, 1943 Section 1, Public Law 690, August 8, 1946 Patent expires April 2, 1963 1 Claim. 1
This invention relates to bearing alloys of the kind which are adapted to be carried by a backing or shell of harder material such as steel.
It is known to use an alloy of lead and copper as a bearing metal and this bonds satisfactorily with a steel shell. It has been found that the distribution of lead in these alloys can be maintained uniform by the addition of small quantities of tin, nickel or silver. In the production of copper-lead bearings advantage is taken of this fact. It is also known that pure silver will bond with a steel shell and that the addition of even small quantities of lead to the silver destroys the bonding properties of the silver. All quantities are given by weight in this specification.
It is an object of the present invention to produce a bearing metal in which silver is introduced in such quantities as to form a major constituent of the metal and in which the bonding properties of the alloy are not spoilt by the presence of lead and silver as alloying agents.
It is a further object of the present invention to introduce into a lead-copper bearing metal alloying constituents which will reduce the duetility of the metal and increase its resistance to REFERENCES CITED The following references are of record in the file of this patent:
