' NITED STATES PATENT OFFICE.
JOHN P. FULLERTON, OF LONDON, ENGLAND.
M ETALLIC ALLOY.
SPECIFICATION forming part of Letters Patent No. 623,209, dated April 18,1899.
Application filed December 20, 1897.
To all whom it may concern:
Be it known that I, JOHN PENDEREIGH FUL- LERTON, a subject of the Queen of the United Kingdom of Great Britain and Ireland, residing at No. 21 Ruby street, Old Kent road, London, in the county of Surrey, England, have invented certain new and useful Improvements in and Connected With Metallic Alloys, (for which I have obtained a patent in Great Britain and Ireland, No. 2,858, dated February 7, 1896;) and I do hereby declare that the following is a full, clear, and exact description of the invention and one which will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in and connected with metallic alloys.
The object of the invention is to produce an alloy suitable for the manufacture of gas and waterconnections and fittings by casting them in molds of metal or other suitable material in order that they may receive from the mold a finished surface ready for the market without it being necessary to devote special labor to the work of producing such surface. The improved alloy is also adapted for being cast in chills. It is fusible at a low temperature, expands and solidifies, and is less subject to corrosion than brass.
The materials of this alloy and their ap-' proximate proportions are as follows: lead, ninety-one parts; copper, one part; bismuth, one part; antimony, seven parts; total, one hundred parts.
For some purposes it is found desirable to introduce a small quantity (one per cent.) of tin to reduce friction and give a harder and better bearing than could be obtained by increasing the quantities of any of the four above-mentioned materials; but tin is not an essential ingredient in the construction of my alloy.
The alloying of the four materials enumerated must be effected by the following special process, devised in view of their different fusing-points: These are (in the order in which the respective materials are set out) 617,
Serial No. 662,705. (No specimens.)
1,990", 507, and 1,150 Fahrenheit. If it were attempted to melt the copper and antimony together after merely weighing the proper proportions into the crucible, the difference in their respective fusing points would lead to the volatilization of the antimony before the fusion of the copper had taken place. To prevent such a miscarriage, the copper is reduced to small particles. This reduction is convenientlyefiected by a smooth file. A small quantity (seven pounds to one hundred pounds of the alloy) of lead is heated to the fusing-point of copper, and then all the copper-dust is sprinkled over it and Well stirred into it. The antimony, having been previously melted in another vessel, has the said mixture of copper and lead added to it. The remainder of the lead is then added, and finally all the bismutha The whole is Well amalgamated by stirring.
I claim 1. The improved homogeneous metallic alloy consisting of ninety-one parts of lead, one part of copper, one part of bismuth and seven parts of antimony to every one hundred parts of the alloy, produced by the process and for the purpose described.
2. The improved process for producing a homogeneous alloy of lead, copper, bismuth and antimony, consisting in taking a small portion of the lead, heating it to the melting point of copper, then introducing into this molten lead the copper in a finely-divided state or dust, stirring the while, then adding this mixture of copper and lead to the anti-' mony which latter has been melted in a separate pot, then adding the remainder of the lead and finally the bismuth; the whole being stirred until thoroughly amalgamated.
In witnesswhereof I have hereunto affixed my signature, in presence of two witnesses,

JOSEPH LAKE, WARWICK I-IY. WILLIAMS.
