Complete Specification Left, 3rd Nov., 1896-Accepted, 9th Jan., 1897
PROVISIONAL SPECIFICATION.
Improvements in and connected with Metallic Alloys.
We, JOHN PENDEREIGH FULLERTON of No. 21 Ruby Street, Old Kent Road,
in the County of Surrey, Inventor, and ARTHUR BASSETT KING-CHURCH of
No. 3 Cheyne Gardens, Chelsea, in the County of Middlesex, Gentleman, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to improvements in and connected with metallic alloys.
The object of it is to produce an alloy suitable for the manufacture of gas and
water connections and fittings by casting them in moulds of metal or other suitable
material; in order that they may receive from the mould, a finished surface ready
for the market without it being necessary to devote special labour 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 approximate proportions are as follows:-

The materials of this alloy and their approximate proportions are as follows:-
Lead
Copper
Bismuth
Antimony

7
100
These proportions may be varied.
The alloying of the four materials enumerated must be effected by a special
process, devised in view of their different fusing points. These are (in the order
in which the respective materials are set out) 617°, 1990°, 507° and 1150° F. If it
were attempted to melt the copper and antimony together, after merely weighing
the proper proportions into the crucible the differences in their respective fusing
points would lead to the volatilisation of the antimony before the fusion of the
copper had taken place. To prevent such a miscarriage, the copper is reduced to
small particles, as by filing with a small file. A small quantity of lead is heated
to the fusing point of copper and the copper dust is sprinkled over it and well
stirred into it. The antimony, having been previously melted in another vessel,
has the mixture of copper and lead added to it. The remainder of the lead is then
added, and, finally, all the bismuth.
Dated this 7th day of February 1896.

small particles. This reduction is conveniently effected by a smooth file. A small
quantity of lend is heated to the fusing point of copper and the copper dust is
sprinkled over it and well stirred into it. The antimony, having been previously
melted in another vessel, has the mixture of copper and lead added to it. The
remainder of the lead is then added, and, finally, all the bismuth.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved alloy, as set forth.
2. The herein before described improved process for effecting the alloying of lead,
copper, bismuth and antimony.
