Office of the Commissioners of Patents on the 29th September 1882..
JAMES WEBSTER of Solihull in the County of Warwick, Engineer, "IMPROVE-
MENTS IN THE MANUFACTURE OF BISMUTH BRONZE OR METALLIC ALLOY."
The object of this invention is to produce a bismuth bronze or metallic alloy or
alloys, suitable for use in sea-water; for telegraph and music wires; for useful
domestic articles; and for other similar purposes.
In all cases the "parts" of the metals used are parts by weight.
I make a hard bismuth bronze or alloy, for use in salt-water, and for telegraph
and music wires, as follows:-
I melt the said metals in a suitable furnace or crucible and, at the same time,
thoroughly amalgamate them; and then run the amalgam, alloy, or bismuth
bronze, thus produced, into moulds of any convenient shape or form, for future
use, as desired.
This bismuth bronze is a hard, tough, and sonorous metallic alloy; which I, by

page_text: preference, use for ships' screw-propeller blades, tubes, and other appliances in sea-
water; it being specially prepared to withstand the destructive influence of the
hydro-chloric acid in salt-water. In consequence of its toughness, it is well-suited
for telegraph wires, and other similar purposes where much strain has to be borne
by its wires. From its sonorous quality, it is well adapted for music wires.
for any similar purposes to the preceding.
Also
For useful domestic purposes and other articles greatly exposed to atmospheric
influence, I prefer to slightly vary the previous alloy, thus:-

"IMPROVE
JAMES WEBSTER of Solihull in the County of Warwick, Engineer,
MENTS IN THE MANUFACTURE OF BISMUTH BRONZE OR METALLIC ALLOY,"
The object of this invention is to produce a metallic alloy or alloys, which
I denominate bismuth bronze,' suitable for use in sea-water; for telegraph and
music wires; for useful domestic articles; and for other similar purposes.
In all cases herein, the 'parts' of the metals used; are parts by weight.
In carrying out my said invention, for a hard bismuth bronze or alloy, for use in
salt-water, and for telegraph and music wires:
I melt the said metals in a suitable furnace or crucible and, during the process;
thoroughly mix and combine them; and then, while in the molten state, run the
mixture, alloy, or bismuth bronze, thus produced, into moulds of any convenient
shape or form, for future use or sale, as required.
This bismuth bronze is a hard, tough, and sonorous metallic alloy, which I, by
preference, use in the manufacture of ships' screw-propeller blades, shafts, tubes,
and other appliances employed partially or constantly in sea-water; it being
specially prepared and suited to withstand the destructive action of the hydro-
chloric acid of salt-water. In consequence of its toughness, it is well suited
for telegraph wires, and other similar purposes where much strain has to be borne
by its wires.. From its sonorous quality, it is well adapted for piano and other
music wires; also for any similar purposes to the preceding.
For domestic utensils and other articles, generally exposed to atmospheric
influence, I prefer to slightly vary the previous composition, bronze, or alloy,
thus

page_text: the hard sea-water bronze, and form a durable, bright, and hard bronze or metallic
alloy; suited for the manufacture of domestic spoons, forks, knives, dish-covers,,
hot-water dishes and plates, kettles, tea-pots, jugs, mugs, cups, chamber-ware, cans,
lamps, candle-sticks, and numerous other utensils or articles exposed to atmospheric
influence.
These alloys will resist oxidation, polish well and easily, and keep their
color well.
Having thus fully described and ascertained the nature of my said invention and
the method of performing the same, I desire it to be understood that I do not
restrict myself to the precise quantity of each of the metals, as herein given for
composing the said alloys, as they may be slightly varied in relative quantity or
weight, according to the special quality of the bronze or alloy required, and the
uses to which it is intended to be. applied, without departing from the main,
characteristics of the invention. But what I claim and desire to secure, by the
herein before-mentioned in part recited Letters Patent, is
Firstly The using or mixing of the metal bismuth in the manufacture of bronze
or metallic alloy or alloys.
Secondly The compositions for making bismuth bronze or metallic alloy to suit
various purposes.
Each and all substantially as herein specified.
In witness whereof I, the said James Webster, have hereunto set my hand
and seal this twenty-fourth day of March, in 'the year of our Lord one
thousand eight hundred and eighty-three,
JAMES WEDSIER
