AN IMPROVED METHOD OF MANUFACTURING METALS AND METALLIC ALLOYS
Year: 1884

page_text: I, JOHN LEWTHWAITE of 5 Carlton Place, Halifax in the County of York
.Gentleman do hereby declare the nature of my said Invention for AN IMPROVED
METHOD OF MANUFACTURING METALS AND METALLIC ALLOYS to be as follows:-
"
This Invention relates to a former Patent granted to me and dated the 27th day
of March 1883 N° 1553 and is intended to supply certain omissions etc: made in
the specification relating thereto and which are necessary to be inserted in order
to prevent any misunderstanding of the full intent and meaning of the said
specification, thus I say:
This Invention relates to adding to .or mixing with metals such as iron, tin,
copper, zinc etc or mixtures of the same or any of them and whilst in a molten or
fluid state such titaniferous iron sands or ores or other mineral or metallic sands
ore or ores as are known or found to possess valuable properties but have been
hitherto unavailable from the want of a simple, inexpensive, sure and expeditious
method of utilizing them.
My Invention consists in using various refractory metallic or mineral ores in
a manner hitherto unpractised for the production of improved metals or alloys of
metals having properties highly desirable in the mechanical, constructive and
decorative arts, etc; etc.
For the carrying out of my Invention I take such ore or ores as above referred
to, as I may desire to use, either singly or mixed the same having been reduced to
powder or being already in a finely granulated condition and sprinkle, scatter, or
disseminate it or a mixture of the same by hand or otherwise into, over, or upon
the clear fluid metal intended to be treated, improved, or alloyed, taking care that
no scum or dross shall intervene or the alloying material (the pulverized powdered
or granulated ore or ores) will be lost or wasted and returned as a heavy infusible slag.
My method or process is equally applicable to the Blast, the Cupola, the
Reverberatory or other furnace for smelting etc: or crucible works and can be
profitably and advantageously introduced into any of the known processes for
alloying metals etc: and the qualities kinds proportion or mixtures can be regulated
with such convenient accuracy as enables the operator to produce materials of an
equal or regular quality, strength, texture etc.
The special feature in this Invention is, the method or processes above described
for improving metals or mixtures of metals or alloys of the same and of producing'
thereby other alloys and combinations.

I JOHN LEWTHWAITE of 5 Carlton Place, Halifax in the County of York,
Gentleman, do hereby declare the nature of my said invention for "AN
IMPROVED METHOD OF MANUFACTURING METALS AND METALLIC ALLOYS," and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention relates to a former Patent granted to me and dated the 27th day
of March 1883 N° 1553 and is intended to supply certain omissions etc: made in
the specification relating thereto and which are necessary to be inserted in order
to prevent any misunderstanding of the full intent and meaning of the said
specification thus I say :-
This invention relates to adding to or mixing with metals such as iron, tin,
copper, zinc etc. or mixtures of the same or any of them and whilst in a molten or
fluid state such titaniferous iron sands or ores or other mineral or metallic sands
ore or ores as are known or found to possess valuable properties but have been
hitherto unavailable from the want of a simple, inexpensive, sure and expeditions
method of utilizing them.
My invention consists in using various refractory metallic or mineral ores in a
manner hitherto unpractised for the production of improved metals or alloys of
metals having properties highly desirable in the mechanical, constructive and
decorative arts, etc, etc.
For the carrying out of my invention I take such ore or ores as above referred
to, as I may desire to use, either singly or mixed the same having been reduced to
powder or being already in a finely granulated condition and sprinkle, scatter, or
disseminate it or a mixture of the same by hand or otherwise into, over, or upon
the clear fluid metal intended to be heated, improved, or alloyed, taking care that
no scum or dross shall intervene or the alloying material (the pulverized powdered
or granulated ore or ores) will be lost or wasted and returned as a heavy infusible
slag.
My method or process is equally. applicable to the Blast, the Cupola, the
Reverberatory or other furnace for smelting etc: or crucible works and can be
profitably and advantageously introduced into any of the known processes for
alloying metals etc: and the qualities kinds proportion or mixtures can be regulated
with such convenient accuracy as enables the operator to produce materials of an
equal or regular quality, strength, texture etc.
The special feature in this invention is, the method or processes above described
for improving metals or mixtures of metals or alloys of the same and of producing.
thereby other alloys and combinations by eliminating, discharging or otherwise
facilitating the escape or separation of deleterious and damaging elements or
substances such as phosphorus, sulphur, carbon etc in the form or shape of gases
or-as oxidės.
I do not claim the use of any particular apparatus or mechanism for the purpose
of sprinkling scattering or disseminating the finely pulverized or granulated ore or
ores into, over, or upon the clear molten metal or metals as this may be done by
hand or by any simple mechanical means.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
• The production of a-superior class of iron, steel, bronze, or other metallic
compound by the introduction into the clear molten metal or metals of titanic

page_text: sand or ore or other ore or ores containing certain mineral acids whether the same
be titanic, manganic, tungstic, chromic, or silicic etc etc. in a finely comminuted
form, the same being then in the fittest and best state to produce an electro-
chemical combination of the alloying and improving material or materials with the
metal or metals operated upon.
