JAMES E. HOLDER, 0F GREEN LANE, PENNSYLVANIA.

METAL ALLOY.

No Drawing.

To all whom it may concern:

Be it known that I, JAMES E. HOLDER, a citizen of the United States, residing at Green Lane, in the county of 'Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Metal Alloys, of which the following is a specification.

This invention relates to improvements in metal alloys, and the object is to provide an alloy that will adapt itself to general uses in the reduction or melting down of certain metals, used in the arts for difierent purposes, and the invention consists in combining certain metals by means of a specified method, which will be described later, and

in combining said metals in proportions that may differ under certain conditions, and when intended for use in different metallic combinations.

The invention consists broadly in the method of combining copper and lead, in certain proportions, with any or all of the following, Viz: iron, manganese and phosphorus, in relatively smaller proportions, by

the use of nickel and metallic arsenic.

The approximate proportions of the respective ingredients are as followsz Lead, from 30 to per. cent, I Copper, from 47 to 68 per cent.

Nickel, from 1 to 5 per cent. Metallic arsenic, from to 11} per cent. Manganese, 2% per cent. Phosphorus, T} of 1 per cent. T v Iron,-% of l per cent.

The proportions enumerated above are the approximate relative proportions and their ranges, as they will appear in the resultant.

product.

The method .of carrying out my invention, is as follows First an alloy is made of metallic arsenic and lead andthis is poured into small ingots,

for convenience in handling. Then, copper Specification of Letters Patent. Patent d N6 16 1920 Application filed June 2, 1920. Serial No. 386,052.

and nickel are melted, under suitable cover, and, when the copper and nickel are fluid, a certain portion of plain lead is added. The temperature of the mass is then brought to a hlgh degree, and then the arsenical lead is added to the mass. The entire mass is then drawn, molds.

then well stirred, and skimmed, and run into suitable The introduction of the iron, manganese and phosphorus is a matter that will be determined in each case, any or all of them being added to the mass at different times dur ng the process, and the proportions while subject to variation are always relatively low, for the reason that these elements are included principally for the toughening effect, and for the aid they supply in holding up the lead content.

lVhat I claim is 1. 3A metallic compound containing lead, copper,"nickel, metallic arsenic, manganese, phosphorus and iron in specified.

the proportions 2. A- compound comprising lead, copper,

mass and then adding the arsenical lead,

stirring the entire mass and then running it into molds.

. In testimony whereof I aflix my signature.
