page_text: LETTERS PATENT to John Dyson, Edwin Wilkinson Shirt, and Henry
Shirt, Steel Rollers, of Tinsley Works, near Sheffield, in the County of
York, for the Invention of "IMPROVEMENTS IN THE MODE OF ROLLING STRIPS
Sealed the 10th September 1858, and dated the 11th May 1858.
PROVISIONAL SPECIFICATION left by the said John Dyson, Edwin
Wilkinson Shirt, and Henry Shirt at the Office of the Commissioners of
Patents, with their Petition, on the 11th May 1858.
We, JOHN DYSON, EDWIN WILKINSON SHIRT, and HENRY SHIRT, Steel
Rollers, of Tinsley Works, near Sheffield, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MODE
OF ROLLING STRIPS OF STEEL FOR CRINOLINE AND OTHER PURPOSES," to be as
follows:-
At present steel for crinoline and such purposes is rolled in plates or sheets
of about 10 feet in length; we propose to roll it in long strips, in such manner
as to reduce it to the requisite guage; this we accomplish after the strips have.
been rolled in single thicknesses to No. 17 guage, by doubling or folding the
strips and passing them through the rolls in two or more thicknesses; and by
this means we reduce them to No. 22 guage, or any less guage that may be t
desired, so as to obviate the necessity of cold rolling for many purposes. We
also propose to coil the strips in the heating furnace, so that they may be

passed between side guides attached in the ordinary manner to the rolls, but in
addition to the side and bottom guides, we apply a top guide, which strains the
strip under treatment straight to the rolls.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Dyson, Edwin Wilkinson Shirt, and Henry Shirt in the
Great Seal Patent Office on the 9th November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Joun
DYSON, EDWIN WILKINSON SHIRT, and HENRY SHIRT, of Tinsley Works, near
Sheffield, in tho County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Dyson, Edwin Wilkinson Shirt, and IIenry Shirt, Her special licence
that we, the said John Dyson, Edwin Wilkinson Shirt, and Henry Shirt, our
executors, administrators, and assigns, or such others as we, the said John
Dyson, Edwin Wilkinson Shirt, and Henry Shirt, our executors, adminis-
trators, 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 THE MODE OF ROLLING STRIPS OF STEEL FOR
CRINOLINE AND OTHER PURPOSES," upon the condition (amongst others) that we,
the said John Dyson, Edwin Wilkinson Shirt, and Henry Shirt, 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 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 John Dyson, Edwin Wilkinson Shirt,
and Henry Shirt, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say):-
Our Invention applies to a mode of rolling steel of small guage, for crinoline

page_text: and various other purposes, in strips of greater length than the system of
rolling which at present obtains, admits of. By the ordinary mode, steel for
such purposes is rolled in sheets of about ten feet in length. We purpose
after it has been reduced singly to No. 17 guage, which may be accomplished
by the present process, to reduce it to the requisite guage in such lengths as
may be required, by folding each length or strip and passing it in two or more
thicknesses between the rolls. This process will have the result of reducing
the strip to so small a guage as for many purposes to obviate the necessity of
cold rolling. The strips before entering between the rolls are passed through
guides. Of the side guides, one is fixed and the other moveable, so as to
admit of being adjusted to the width of the strips which are being rolled, and
to keep the folds parallel. The bottom plate or guide is also fixed, but the
top guide is so arranged that pressure may be applied to it and through it
upon the strips for the purpose of keeping them firmly together.
Having now described the nature of our said Invention, and the manner
in which the same is or may be carried into effect, we wish it to be understood
that what we desire and intend to secure by the above in part recited Letters
Patent is, the rolling of steel in strips doubled or folded.
In witness whereof, we, the said John Dyson, Edwin Wilkinson Shirt,
and Henry Shirt, have hereunto set our hands and seals, this Sixth
of November, in the year of our Lord One thousand eight hundred
and fifty-ciglit.
