PETERS. BRAUCHER, OF READING, PENNSYLVANIA.
SOFT-METAL ALLOY.
To all whom it may concern:
Be it known that I, PETER S. BRAUCHER,
a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Soft-Metal Alloys, of which the following is a specification.
This invention relates to improvements in soft metal alloys and the object in the present instance is to provide an improved alloy suitable for use as a soft metal bearing metal, one in which the cost is maintained at approximately the minimum, and in which the desired toughness is obtained without that brittle hardness that so often accompanies the effort at toughness.
A further object is to provide, in the composition, an element that Will act as a cleansing agent or scavenger, so that whatever grit there may be contained in the mixture, will be absorbed or nullified.
The distinguishing feature of my present invention therefore is the presence of phosphorus, which is added to the other constituents of the alloy before melting, orwhile in a molten state.
The addition of phosphorus to the ordi-- nary constituents of a soft metal bearing metal will toughen the resultant product, remove all tendency togrit, and as a consequence, result in. better lubrication with ordinary lubricants, thus reducing very materially the tendency to overheated bear-' mgs.
An important practical advantage of the present invention when used in connection with the ordinary type of soft bearing metal comprising as its principal constituents, lead, tin and antimony, is that its use permits of the formation of a satisfactory bearing metal containing less of the relatively high priced toughening elements, tin

any given lubricant.
It has been definitely determined that I the phosphorus content will cause a more satisfactory fusing of the metal than could be effected, for instance, by the use of caustic soda in its stead, while at the same time the phosphorus acts as a scavenger in cleansing up the metal and neutralizing the foreign particles that would otherwise tend to grit.
The proportionate amount of phosphorus as well as the character of some of the other constituents used, may vary, while the characteristic advantages obtained by the use of phosphorus Will still obtain.
My present invention contemplates an alloy formed of lead, tin, antimony and phosphorus in substantially the following proportions Lead 89 parts. Tin 7 parts. Antimony 3% parts. Phosphorus 0?; parts.
The above named constituents may. be mlxed together before-melting, but I prefer to form a molten mixture of the tin and antimony, add thereto a portion of the phosphorus to be used, then add the product thus obtained to molten lead and then, to the last named mixture, add the remainder of the phosphorus to be used.
It has been determined that-in the resultmetals by the use of my present invention has beenpositively established by actual use over a. comparatively long period of time.
What I claim as my invention is 1. A soft metal .alloy containing eightynine per cent. of lead and one-quarter of one per cent. of phosphorus.
2. A soft metal alloy containing eightynine per cent. of lead, one-quarter ofone per cent. of phosphorus and the remainder composed of tin and antimony.
3. A soft metal alloy containing eightynine per cent. of lead, one-quarter of one per cent. of phosphorus and the remainder of tin and antimony in the proportions of two parts of tin to one part of antimony.
4. An alloyconsisting of eighty-nine parts lead, seven and one-half parts tin, three and one-quarter parts antimony, and 10 one-quarter of one part phosphorus.
In testimony whereof I afiix my signature.
PETER S. BRAUCHER.
