IMPROVEMENTS IN THE MANUFACTURE OF Hoor IRON AND LIGHT BARS AND RODS AND OTHER DESCRIPTIONS OF IRON
Year: 1879

page_text: LETTERS PATENT to William Hassalwood Carmont, of Fairfield, in the County
of Lancaster, Iron Manufacturer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF Hoor IRON AND LIGHT BARS AND RODS AND OTHER
DESCRIPTIONS OF IRON."
PROVISIONAL SPECIFICATION left by the said William Hassalwood Carmont
at the Office of the Commissioners of Patents on the 16th October 1879.
WILLIAM HASSALWOOD CARMONT, of Fairfield, in the County of Lancaster, Iron
Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF HOOP IRON AND LIGHT
BARS AND RODS AND OTHER DESCRIPTIONS OF IRON."
My Invention consists in combining steel with iron for making hoop or bar iron
in the following manner:-
I form the pile to be rolled of two hollow or channelled bars placed with their
edges together, between which I place one or more steel bars. When this pile is
placed in the furnace, the steel being protected on all sides by the channelled iron is
not injured by overheating. When rolled down into hoops or bars a very superior
quality of iron is produced. In some cases I enclose the steel in four or more pieces
of iron instead of the two channelled bars.

the said William Hassalwood Carmont in the Great Seal Patent Office on the
8th April 1880.
WILLIAM HASSALWOOD CARMONT, of Fairfield, in the County of Lancaster, Iron
Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF HOOP IRON AND LIGHT
BARS AND RODS AND OTHER DESCRIPTIONS OF IRON."
My Invention consists in an improved mode of combining steel with iron for
making hoop or bar iron.
And in order that my Invention may be more fully understood I will proceed to
describe the means pursued by me.
I form the pile to be rolled of two hollow or channelled bars of iron, which are
placed with their edges together, and between which I place one or more steel bars,
or scrap steel, or a combination of steel and iron scrap. When this pile is in the
furnace, the steel being protected on all sides by the channelled iron is not injured
by over heating. When rolled down into hoops or bars a very superior quality of
metal is produced.
In some cases I enclose the steel in four or more pieces of iron instead of the two
chanuelled bars.
I make the hollow or channelled bars in the following manner :-I turn the forge
or roughing rolls to the form required for making the hollow or channelled bars,
and I can then roll at once from the puddled or scrap bloom, thereby economising
time, labour, and material.
Having thus stated the nature of my Invention and described a convenient mode
of performing the same, I wish it to be understood that I do not intend to limit
myself to the details given, as the same may be varied or modified according to
the size of the hoops or bars to be produced, or the purpose for which they are
required.
I claim the improved mode of combining steel with iron for manufacturing hoop
and othe descriptions of iron as described.
In witness whercof, I, the said William Hassalwood Carmont, have hereunto set
my hand and seal, this Seventh day of April, One thousand eight hundred
and eighty.
