AN IMPROVEMENT IN THE MANUFACTURE OF CAST-STEEL HOOPS AND CYLINDERS
Year: 1857

page_text: LETTERS PATENT to Joshua Moss, Thomas Gamble, and Joseph Gamble,
all of Sheffield, in the County of York, Steel Manufacturers, for the
Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF CAST-STEEL HOOPS
AND CYLINDERS."
Sealed the 22nd June 1858, and dated the 23rd December 1857.
PROVISIONAL SPECIFICATION left by the said Joshua Moss, Thomas
Gamble, and Joseph Gamble at the Office of the Commissioners of
Patents, with their Petition, on the 23rd December 1857.
We, JOSHUA Moss, THOMAS GAMBLE, and JOSEPH GAMBLE, all of Sheffield,
in the County of York, Steel Manufacturers, do hereby declare the nature of
the said Invention for "Ax IMPROVEMENT IN THE MANUFACTURE OF CAST-STEEL
HOOPS AND CYLINDERS," to be as follows:--
The object of our Invention is to produce a hoop or cylinder of steel solid
throughout, and without joint or weld, to be afterwards rolled into tyres for
railway and other wheels; but we do not limit ourselves to the making of
hoops for tyres, as after the hoop is made in the manner hereafter described
it may be used for many other purposes. We are aware that various
attempts have been heretofore made to cast solid steel hoops, but not with
success, on account of a portion having been formed with a honeycombed
surface. Now, our Invention consists in pouring the metal into a suitable
mould placed vertically through two mouths or conduits at the upper part
and near the two top sides of the mould or mould casing. These conduits or

page_text: mouths rise sufficiently high from the periphery or outer edge of the annular
space into which the metal is to be run to receive the whole of the honeycomb
or top surface of the metal, consequently the annular space in the mould is
entirely filled with solid metal without any hollow or honeycombed surface.
The whole of this surface is received in the two mouths or conduits, and being
cut off from the hoop or cylinder after being removed from the mould, there
remains a solid cast-steel ingot in the form of a hoop or cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joshua Moss, Thomas Gamble, and Joseph Gamble in the
Great Seal Patent Office on the 23rd June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, JosИUA
Moss, THOMAS GAMBLE, and JOSEPH GAMBLE, all of Sheffield, in the County
of York, Steel Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of December, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Joshua Moss, Thomas Gamble, and Joseph Gamble, Her special
licence, that wo, the said Joshua Moss, Thomas Gamble, and Joseph Gamble,
our executors, administrators, and assigns, or such others as the said
Joshua Moss, Thomas Gamble, and Joseph Gamble, our executors, admi-
nistrators, 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 "AN IMPROVEMENT IN THE MANUFACTURE OF CAST-STEEL
HOOPS AND CYLINDERS," upon the condition (amongst others) that we, the shid
Joshua Moss, Thomas Gamble, and Joseph Gamble, or one of us, our
executors or administrators, by an instrument in writing under our, or their;
or one of our or their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same

Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said Joshua Moss, Thomas Gamble, and
Joseph Gamble, do hereby declare the nature of our said Invention, and in

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say:-
"
The object of our Invention is to produce a hoop or cylinder of steel solid
throughout, and without joint or weld, to be afterwards rolled into tyres for
railway and other wheels; but we do not limit ourselves to the making of
hoops for tyres, as after the hoop is made in the manner hereafter described
it may be used for many other purposes. We are aware that various
attempts have been heretofore made to cast solid steel hoops, but not with
success, on account of a portion having been formed with a honeycombed
surface. Now, our Invention consists in pouring the metal into a suitable
mould placed vertically through two mouths or conduits at the upper part
and near the two top sides of the mould or mould casing. These conduits or
mouths rise sufficiently high from the periphery or outer edge of the annular
space into which the metal is to be run to receive the whole of the honeycomb
or top surface of the metal, consequently the annular space in the mould is
entirely filled with solid metal without any hollow or honeycomb surface.
The whole of this surface is received in the two mouths or conduits, and being
cut off from the hoop or cylinder after being removed from the mould, there
remains a solid cast-steel ingot in the form of a hoop or cylinder.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim the manufacture
of cast-steel hoops and cylinders in the manner herein-before described.
In witness whereof, we, the said Joshua Moss, Thomas Gamble, and
Joseph Gamble, have hereunto set our hands and seals, this Twenty-
second day of June, One thousand eight hundred and fifty-eight.
