Definitions
- 'My invention consists in a process of manufacture of a metallic alloy, from which gold pens can be made, which secures greater stiffness and elasticity in the pen, giving it the firmness of the steel pen, combined with the durability and freedom from corrosion of the gold one, while the pens formed from the alloy produced by my process can be rc-pointed without losing their elasticity in the annealing process, as do the pens formed from the customary alloy of gold, silver, and copper.

Description
UNITED STATE$ PATENT OFFICE.
JOHN HOLLAND, OF CINCINNATI, OHIO.
IMPROVEMENT IN ALLOYS FOR THE MANUFACTURE OF PENS.
Specification forming part-of Letters Patent No. 132,008, dated October 8, 1872.
To all whom it may concern:
Be it known that I, JOHN HOLLAND, of Cincinnati, Hamilton county, Ohio, have invented a certain new and useful Improvement in the Manufacture of Gold Pens, of which the following is a specification:
Nature and Objects of Invention.
'My invention consists in a process of manufacture of a metallic alloy, from which gold pens can be made, which secures greater stiffness and elasticity in the pen, giving it the firmness of the steel pen, combined with the durability and freedom from corrosion of the gold one, while the pens formed from the alloy produced by my process can be rc-pointed without losing their elasticity in the annealing process, as do the pens formed from the customary alloy of gold, silver, and copper.
General Description.
In the process of preparing my alloy I first take four pennyweights of chemically-pure silver and melt it, to which I add one pennyweight of platinum, together with a piece of Claim.
The herein-described alloy, for the manufacture of gold pens, of the ingredients, and in the proportions} substantially as and for the purpose specified.
In testimony of which invention I hereunto set my hand.
JOHN HOLLAND.
\Vitn esses FRANK MILLWARD, I. L. WARTMANN.
