page_text: LETTERS PATENT to George Scott, of 2, Bond Court, Walbrook, in the City
of London, for an Invention of IMPROVED MANUFACTURE OF TRIPLE
ALLOYS OF MANGANESE, THE TITANIFEROUS STEEL SAND OF TARANAKI,
NEW ZEALAND, AND CARBON."
PROVISIONAL SPECIFICATION left by the said George Scott at the Office
of the Commissioners of Patents on the 8th February 1882.
GEORGE SCOTT of 2 Bond Court Walbrook in the City of London. IMPROVED
MANUFACTURE OF TRIPLE ALLOYS OF MANGANESE, THE TITANIFEROUS STEEL
SAND OF TARANAKI, NEW ZEALAND AND CARBON.
The object of this Invention is the manufacture of triple alloys consisting of
Manganese the Titaniferous steel sand of Taranaki and Carbon known under the
names of Speigeleisen and Ferro-Manganese. The economy and advantage in the
method of manufacture by my Invention is effected by using the Titaniferous steel
sand of Taranaki instead of ordinary iron reduced to a granular state, the process
of granulating ordinary iron being both troublesome and costly whereas the
Titaniferous steel sand is supplied by nature in the required form for the manu-
facture of Speigeleisen and Ferro-Manganese and the cost and trouble of granulating
iron is avoided.
According to this Invention I use the Titaniferous steel sand in the place and
stead of granulated iron combining the same with Manganese and Carbon. The
several constituent parts being reduced to a granular state are mixed in proportions
regulated by the actual amount of metallic Manganese contained in the peroxide
of Manganese the actual amount of metallic iron or steel contained in the Titani-
ferous sand used in forming the alloys either of Speigeleisen or Ferro-manganese
with a proportion of Carbon admixed and adjusted in like manner.

page_text: The mixture of these constituent parts having been effected the same is placed
in graphite or plumbago crucibles or similar vessels the surface being covered with
powdered glass or silicious sand or other like substance.
In this state the contents are submitted to the action of a Furnace and raised
gradually to a high temperature sufficient to effect the fusion of the mixture. The
employment of the Titaniferous steel sand in the place of granulated iron reduces
greatly the cost in the manufacture of both Speigeleisen and Ferro-Manganese.
An adhesive carboniferous solution may be made of sufficient consistency to
combine by admixture the constituent materials of manganese and the titaniferous
steel sand into a substance capable of being moulded after the manner of a brick,
then dried and afterwards submitted to a furnace for fusion.

GEORGE SCOTT, of 2 Bond Court Wallbrook in the City of London. IMPROVED
MANUFACTURE OF THE TRIPLE ALLOYS CONSISTING OF MANGANESE, THE TITANI-
FEROUS STEEL SAND OF TARANAKI (NEW ZEALAND) AND CARBON.
The object of this Invention is the manufacture of triple alloys consisting of
Manganese, the Titaniferous steel sand of Taranaki and other places in New
Zealand where such quality of sand may be found, and Carbon known under the
names of Speigeleisen and Ferro-Manganese.
The economy and advantage in the method of manufacture of my Invention is
effected by using the Titaniferous steel sand of Taranaki and other places in New
Zealand where such quality of sand may be found, instead of ordinary iron reduced
to a granular state, the process of granulating ordinary iron being both troublesome
and costly, whereas the Titaniferous steel sand is supplied by nature in the required
form for the manufacture of Speigeleisen and Ferro-Manganese, and the cost and
trouble of granulating iron is avoided.
According to this Invention I use the Titaniferous steel sand in the place and
stead of granulated iron, combining the same with Manganese and Carbon. The
several constituent parts being reduced to a granular state are mixed in proportions
regulated by the actual amount of metallic Manganese contained in the peroxide
of Manganese the actual amount of metallic iron or steel contained in the Titani-
ferous sand used in forming the Alloys either of Speigeleisen or Ferro-Manganese
with a proportion of Carbon admixed and adjusted in like manner.
The mixture of these constituent parts having been effected the samo is placed
in graphite or plumbago crucibles or similar vessels, the surface being covered with
powdered glass or silicious sand or other like substance.
In this state the contents are submitted to the action of a furnace, and raised
gradually to a high temperature sufficient to effect the fusion of the mixture.
The employment of the Titaniferous steel sand in the place of granulated
iron reduces greatly the cost in the manufacture of both Speigeleisen and Ferro-
Manganese.
An adhesive carboniferous solution may be made of sufficient consistency to
combine by admixture the constituent materials of Manganese and the Titaniferous
steel sand into a substance capable of being moulded after the manner of a brick,
then dried and afterwards submitted to a furnace for fusion.
Having now described the nature of my said Invention and in what manner the
same is to be performed I declare that I claim :—
The manufacture of triple Alloys composed of Manganese, Titaniferous steel sand
of New Zealand, and Carbon as set forth.
In witness whereof I the said George Scott have hereunto set my hand and
seal this Third day of August in the year of our Lord, One thousand
