A NEW COMPOSITION OF DIFFERENT METALS OR METALLIC SUBSTANCES."
Year: 1853

page_text: LETTERS PATENT to Edme Augustin Chameroy, of Paris, France,
Manufacturer, for the Invention of "A NEW COMPOSITION OF
DIFFERENT METALS OR METALLIC SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Edme Augustin
Chameroy at the Office of the Commissioners of Patents, with his
Petition, on the 6th January 1858.
I, EDME AUGUSTIN CHAMEROY, do hereby declare the nature of the
said Invention for "A NEW COMPOSITION OF DIFFERENT METALS OR
METALLIC SUBSTANCES" to be as follows:-
This Invention consists in the production of a metallic compound
which has the properties of solidity, hardness, unalterability, facility of
soldering, capable of being melted at low temperatures, and having the
property of being easily moulded into any required form. In the

page_text: formation of this metal pounded iron ore, or pounded cast iron, or other
metal difficult of fusion, is employed, squeezed into a mass by pressure,
and soldered by one or more metals casy of fusion at low temperatures,
such as tin, lead, zinc, and bismuth. In order to prepare the metal a
furnace fitted with a damper, in order to regulate the action of the fire
at will, is employed; on this furnace is placed a cauldron of iron of a
suflicient thickness to stand the heat; one part of some very fusible
metal, either a mixture of lead and tin or any other metallic compound
having the property of ready fusion at low temperatures, and of turning
over or soldering a metal less easy to fuse, is placed in the cauldron; to
this melted metal is added about four, parts of pounded iron ore and
pounded cast iron, after having been steeped in a solution of ammonia
or chlorine, or any other preparation capable of cleansing the metal and
removing any verdigris from it; these are mixed well together, so that
the particles of iron may be well tinned all over, taking care to regulate
the fire so that the temperature does not get too high and cause oxida-
tion in the metal. In this state the metal is ready for use, and may be
formed into moulds for the formation of statues, columns, candelabras,
monumental fountains, chinney tops, cylinders, hollow or solid, fly
wheels, pulleys, and numerous other articles usually cast in moulds.
Since this metal melts and cools quickly, moulds composed of cast iron
or copper may be used advantageously, by which means the articles are
turned out smooth and sharp, without requiring to be dressed in a lathe
or any other machine. This metal being also malleable, it may be cast
into plates of any required thickness, on suitable tables, and then passed
between rollers and laminated to any extent, according to the use to
which it is to be put to. These plates are principally intended for
roofing for houses, and may also be used in the construction of tubes,
tanks, and metal sheets, the metal may also be run into pigs, and left
in that state to be sold for casting purposes.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edme Augustin Chameroy in the Great Seal
Patent Office, on the 1st July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
EDME AUGUSTIN CHAMEROY, of Paris, France, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of January, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Edme Augustin Chameroy, Her special license
that I, the said Edme Augustin Chameroy, ny executors, administrators,
and assigns, or such others as I, the said Edme Augustin Chameroy,
my exccutors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "A NEW
COMPOSITION OF DIFFERENT METALS OR METALLIC SUBSTANCES," upon the
condition (amongst others) that I, the said Edme Augustin Chameroy,
by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edme Augustin Chameroy, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say:
My said Invention relates to the manufacture or production of a
commercially valuable metallic compound possessing the several pro-
perties or qualities of solidity, hardness, facility of soldering, melting
at low temperatures, and tractability in moulding to any required
form, whilst its nature is peculiarly unchangeable. As the base or

page_text: chief ingredient of this compound I employ pounded or reduced iron
ore, or reduced cast iron, or other metal difficult of fusion. Such
matter I' squeeze or press together into a solid mass, and then solder it
so as to incorporate the particles well together by the use of one or
more metals easily fusible at low temperatures, such as tin; lead, zinc,
and bismuth And in order to prepare this compound metal
employ
a furnace fitted with a damper for the regulation of the heat at pleasure,
and on this furnace is placed, a cauldron or metal receiver to hold the
materials. One part of some very fusible metal, either a mixture of
lead and tin, or any other metallic compound possessing the property of
fusion at low temperatures, and of tinning over or soldering a metal
less easy to fuse, is now placed in this cauldron and melted. To this
molten metal is then added about four parts of the pounded iron or
pounded cast iron, steeped in a solution of ammonia or chlorine, or
other preparation capable of cleansing the metal. The mass is now
well mixed together, so that the particles of iron may be well tinned all
over, taking care to regulate the fire so that oxidation shall not ensue.
When so treated, the mass is fit for usc, and it may be poured into
moulds for being shaped into a variety of articles; such, for example, as
statues, columns, candelabra, fountains, and the like, as well as into
cylinders, fly wheels, pulleys, and other details ordinarily cast in moulds.
As this compound melts and cools down very rapidly, moulds composed
of cast iron, copper, or other hard metal may be used, so that the
articles cast in this way may be turned out smooth and sharp, without
requiring to be subsequently dressed. And as the metal is also malle-
able, it may be cast into plates of any required thickness, and then
passed between the rollers for mechanical reduction in the manner of
rolling out ordinary boiler plates. Such plates are principally intended
for roofing houses and for general covering purposes, but they may also
be employed in the manufacture of tubes, tanks, and sheets for various
uses. The crude metal may also be run into pigs in the usual way,
and sold in that state for the usual casting or other manufacturing
purposes.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or

page_text: carried into effect, I would observe, in conclusion, that I do not confine
or restrict myself to the precise details or arrangements which I have
had occasion to describe or refer to, as many variations may be made
therefrom without deviating from the principles or main features of my
Invention; but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part
recited Letters Patent, is,-
First, the system or mode of manufacturing or producing compound
or composite metals, as herein-before described.
Second, the system or mode of manufacturing or producing solid
metals from disintegrated metallic particles soldered or joined and
bound up together by another easily fusible metal.
In witness whereof, I, the said Edme Augustin Chameroy, have
horeunto set my hand and seal, the Twenty-seventh day of
June, One thousand eight hundred and fifty-three.
