Street, in the County of Middlesex, Merchant, John Bailey Davies, of
20, Gresham Street, in the City of London, Merchant, and William
Richard Dawson, of High House, Homerton,in the County of Middlesex
Gentleman, for the Invention of "IMPROVEMENTS IN EXTRACTING METAL
FROM TITANIFEROUS IRON SAND OR MINERALS CONTAINING METALS."
Sealed the 18th April 1867, and dated the 24th October 1866.
PROVISIONAL SPECIFICATION left by the said Henry Davidson Plimsoll,
John Bailey Davies, and William Richard Dawson at the Office of the
Commissioners of Patents, with their Petition, on the 24th October
1866..
We, HENRY DAVIDSON PLIMSOLL, of 35, Great Ormond Street, in the
County of Middlesex, Merchant, JOHN BAILEY DAVIES, of 20, Gresham
Street, in the City of London, Merchant, and WILLIAM RICHARD DAWSON, of
High House, Homerton, in the County of Middlesex, Gentleman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN EXTRACTING
METALS FROM TITANIFEROUS IRON SAND OR MINERALS CONTAINING METALS," to be
as follows:-
Our Invention has for its object the preparation of metals or metallic ores
or substances for smelting, and consists in the use of coal or other fuel in a
pulverised or finely divided state, and titaniferous iron sand or metallic ores
or substances in a similar state, and forming them into a kind of metallic coke

or pulverised coal, or small or pulverised charcoal, or other carbonaceousl
substance, and mix such coal or charcoal or other substance with titaniferous
iron sand, iron filings, or iron ore, or other minerals reduced to or in the
state of small portions or particles. In order to facilitate the requisite
binding of the said materialssilicate of soda or other suitable substance may
be used if necessary; this mixture or incorporated material is then put into
an ordinary coke oven, or retort, or close furnace, and converted into a metallic
coke or agglomerated substance, which is afterwards treated as usual in a
smelting furnace. By using the materials in finely divided portions they are
more easily manipulated as required, and the foreign or deleterious matter is
more readily separated from them. Also the fuel being incorporated with the
material or substance containing metal in the manner above stated there is a
larger distribution and more direct applicationofheating surface to an extended
surfaceof the material under treatment than can be obtained bythe application
of heat in the usual manner. Also the preparation of the materials by the
process of coking obviates the inconvenience which has been found to arise
in the practice of smelting iron from titaniferous iron sand from the
minuteness of its particles when acted upon by the blast of an ordinary
blast furnace, and also from the tendency of the sand to choke the furnace

Richard Dawson in the Great Seal Patent Office on the 24th April

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
DAVIDSON PLIMSOLL, of 35, Great Ormond Street, in the County of Middlesex,
Merchant, JOHN BAILEY DAVIES, of 20, Gresham Street, in the City of
London, Merchant, and WILLIAM RICHARD DAWSON, of High House, Homerton,
in the County of Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of October, in the year of our Lord
One thousand eight hundred and sixty-six,in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Henry Davidson Plimsoll, John Bailey Davies, and William Richard Dawson,
Her special licence that we, the said Henry Davidson Plimsoll, John Bailey
Davies, and William Richard Dawson, our executors, administrators, and

page_text: assigns, or such others as we, the said Heary Davidson Plimsoll,.John
Bailey Davies, and William Richard Dawson, our executors, 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 "IMPROVEMENTS IN EXTRACTING METALS FROM TITANIFEROUS IRON
SAND OR MINERALS CONTAINING METALS," 'upon the condition (amongst others)
that we, thesaid Henry Davidson Plimsoll, John Bailey Davies, and William
Richard Dawson, our executors or administrators, by an instrument in writing.
under our, or their, or one of their hands and seals, 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 we, the said Henry Davidson Plimsoll, John Bailey:
Davies, and William Richard Dawson, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement (that is
to say):
Our Inventionof" Improvements in Extracting Metals from Titaniferous
Iron Sand or Minerals containing Metals, "has for its object the preparation of
metals or metallic ores or substances for smelting, and consists in the use of
coal or other carbonaceous matter in a pulverized or finely divided state, and
titaniferous iron sand or metallic ores or substances in a similar state, and in
the preparation of such materials for smelting by the application of heat to
them so as either to form them into a kind of metallic coke or agglomerated
substance, or otherwise to make them ready for smelting. For this purpose
we take small or pulverized coal, or small or pulverized charcoal, or other
carbonaceous substance, and mix such coal or other substance with titaniferous
iron sand, iron filings, or iron ore, or other minerals reduced to or in the state
of small portions or particles; we then place the said mixture in a retort,
coke oven, or other closed heating vessel or chamber, or in a cementing
furnace, and provided the carbonaceous matter employed does not contain
sufficient bitumen or other binding materials silicate of soda or other suitable
binding substance or material may be used therewith. After the said process
the mixed or incorporated matter composed of metallic and carbonaceous
substances, chemically combined by the operation of heat, is treated in the
ordinary way of smelting iron or other metals either in blast or other furnaces.

page_text: By using the materials in finely divided portions they are more easily manipu-
lated as required, andtheforeign or deleterious matter is more readily separated
from them. Also the fuel being incorporated with the material or substance
containing metal in the manner above stated there is a larger distribution
and more direct application of heating surface to an extended surface of the
material under treatment than can be obtained by the application of heat in
the usual manner to metallic ores. Also the preparation of the materials by
the process of coking obviates the inconvenience which has been found to arise
from the means hitherto used for smelting iron from titaniferous iron sand
owing to the minuteness of its particles when acted upon by the blast of an
ordinary blast furnace, and also from the tendency of the sand to choke the
furnace.
Having thus described the nature of the said Invention, andin what manner
the same is to be performed, we hereby declare that what we claim as of our
Invention is, the use of titaniferous iron sand or minerals containing metals
in a pulverized or finely divided state mixed with coal or other carbonaceous
matter in a similar state, and the preparation of such materials for smelting
by the application of heat in the manner described.
In witness whereof, we, the said Henry Davidson Plimsoll, John Bailey
Davies, and William Richard Dawson, have hereunto set our bands
and seals, the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven..
