Be it'k nown that We,DANIEL OHARA, DAN- IEL W. ELDREDGE, and Jorm LOGAN, of Wei.-
tham, in the county of Middlesex and State of 5 Massachusettsdiave invented certain new and useful Improvements in Alloys,- of which the following is a specification.
alloy or compound metal which shall be practim cally non-magnetic, inoxidizeble, and willhave a suitable coefficient of expansion toadaptit for use as the material for one of the parts of the rim of a compcnsation-bulance for watches or chronometers. I 5 Our improved alloy consists of a, compound ".of platinum, copper, nickel, and gold in about .the following proportions: platinum,,from "sixty (60) to seventy-five (7,5).parts; copper,
twenty-four (24) parts; nickcl,eight (8) parts; 20 gold, eight (8) parts. y i We do not limit ourselves to theexact proportions of copper,nickel,and gold abovespecified, but may vary the some within'rea'sonabie limits without departing from the spirit of our invention. 25
'WVe claim- An alloy or compound composed ofplatinu m,
v 4 copper, nickel, and gold, in. substantially the Ourinvention has for its objectto provide on eight parts of nickel, and eight parts of gold as set forth.
