NITED STATES PATENT OFFICE.
DANIEL OHARA, DANIEL XV. ELDREDGE, AND JOHN LOGAN, OF \VALTHAM,
' MASSACHUSETTS.
ALLOY.
SPECIFICATION forming part of Letters Patent No. 385,945, dated July 10, 1888.
l Application filed March 2. 1888. I Serial No. 265,925. (No specimens.)
To all whom it may concern:
Be it known that we, DANIEL OHARA, DAN- IEL W. ELDREDGE, and JOHN LOGAN, of Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Alloys, of which the followingis a specification.
Our invention has for its object to providean alloy or compound metal which shall be practically non-magnetic, inoxidizabl'e, and sufficiently resilient to adapt it for use asa material for the hair-springs of watch and chronometer balances.
We do not limit ourselves to the exact proportions above specified, but may vary the 20 same within reasonable limits without depart-- ing from the spirit of our invention.
We claim Au alloy or compound metal composed of gold, nickel, and platinum, in substantially the 2 proportions herein stated,
In testimony whereof we have signed ournames to this specification, in the presence of two subscribing witnesses, this 28th day of February, A. D. 1888.
' DANIEL OHARA.
DANIEL W. ELDREDGE.
' JOHN LOGAN.
