Year: 1879

page_text: LETTERS PATENT to Edward Hutchinson, of Darlington, in the County of
Durham, Engincor, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR ROLLING IRON, STEEL, AND OTHER METALS."
Sealed the 21st November 1879, and dated the 13th June 1879.
PROVISIONAL SPECIFICATION left by the said Edward Hutchinson at the
Office of the Commissioners of Patents on the 13th Juno 1879.

EDWARD HUTCHINSON, of Darlington, in the County of Durham, Engineer.
PROVEMENTS IN MACHINERY OR APPARATUS FOR ROLLING IRON, STEEL, AND OTHER
METALS."
This Invention relates to machinery or apparatus for rolling piles, blooms, or
rough pieces of iron, steel, or other metal into bars or plates, and when used for
rolling steel plates from ingots will obviate the necessity of shearing the edges of
such plates, thus avoiding the production of scrap. I employ rolls constructed with
annular grooves, recesses, or spaces between the ends or shoulders of their
cylindrical operating surfaces, and suitable collars, flanges, or parts situate between
such ends or shoulders and the journals in which the roll axes work. The rolls are
(or one of them is) or may be arranged to be capable of adjustment endwise by a
screw or equivalent means for the purpose hereinafter mentioned; a part of one
roll intermediate between its two ends or shoulders is situate over or opposite the
annular groove, recess, or space in the other roll of the pair, and on the said part is
fitted a loose ring or collar, whose periphery enters and works in the annular groove,
recess, or space of the other roll. Each roll of the pair is thus fitted with a loose
ring or collar working at its periphery in an annular groove, recess, or space in (or
opposite a smaller diameter of the other roll, but close to the shoulder of such roll.
Each loose ring or collar is accurately fitted on the roll it surrounds, so as to work
truly in the groove, recess, or space of the other roll.
By adjusting one or both rolls the distance apart of the loose rings or collars may
be regulated to suit the work to be done. Thus not only can the gauge or width
of the bar or plate be regulated as desired, but a good, true, and solid edge may be
obtained. The screw or equivalent means for adjusting the rolls endwise may be
attached to the framing of the machine in any convenient way.

PROVEMENTS IN MACHINERY OR APPARATUS FOR ROLLING IRON, STEEL, AND OTHER
METALS."
The Invention relates to machinery or apparatus for rolling piles, blooms, or rough
pieces of iron, steel, or other metal into bars or plates, and when used for rolling
steel plates from ingots will obviate the necessity of shearing the edges of such
plates, thus avoiding the production of scrap. I employ rolls constructed with
annular grooves, recesses, or spaces between the ends or shoulders of their
cylindrical operating surfaces, and suitable collars, flanges, or parts situate between
such ends or shoulders and the journal bearings in which the roll axes work.
The rolls are (or one of them is) or may be arranged to be capable of adjustment
endwise by a screw or equivalent means for the purpose hereinafter mentioned; a
part of one roll intermediate between its two ends or shoulders is situate over or
opposite the annular groove, recess, or space in the other roll of the pair; and on
the said part is fitted a loose ring or collar, whose periphery enters and works in
the annular groove, recess, or space of the other roll. Each roll of the pair is thus
fitted with a loose ring or collar working at its periphery in an annular groove,
recess, or space in (or opposite a smaller diameter of the other roll, but close
to the shoulder of such roll. Each loose ring or collar is accurately fitted on
the roll it surrounds, so as to work truly in the groove, recess, or space of the
other roll.
By adjusting one or both rolls the distance apart of the loose rings or collars may
be regulated to suit the work to be done. Thus not only can the gauge or width
of the bar or plate be regulated as desired, but a good, true, and solid edge may be
obtained. The screw or equivalent means for adjusting the rolls end wise may be
attached to the framing of the machine in any convenient way. And in order to
a full understanding of my said Invention I now proceed to explain the manner of
carrying it out in practice as illustrated in the accompanying Drawings, whereof
Fig. 1 is an elevation of a machine embodying my improvements.
Fig. 2 is a plan of the same; and Fig. 3 is a section in the line A, B, of Fig. 1.
a and b are two rolls forming a pair, and both journalled in suitable boxes or
bearings in the standards, frames, or cheeks c, d. The upper roll a is capable of
being set towards the lower one b as required by set screws e, as shewn, and is also
adjustable longitudinally by the screw f. The upper roll a is formed with an
annular groove, recess, or space a', and the lower roll with a similar groove, recess,
or space a² is a loose ring or collar fitted truly on the upper roll a, and working
at its periphery in the annular groove, recess, or space b₁ of the lower roll; 6 is a
similar ring or collar fitted truly on the lower roll b, and working at its periphery
in the annular groove, recess, or space a¹ of the upper roll. The rings or collars
a, b, are sufficiently loose on their respective rolls to permit of the upper roll a
(or it may be both rolls) being moved end wise by the screw f (or it may be by
other equivalent device), by which means the distance apart of the rings or collars,
and consequently the width of the bar, can be varied at will. Each roll may have
more than one annular recess and ring arranged and operating as described.
Having described the nature of my said Invention, and explained in what
manner the same is to be or may be performed or carried into practical effect, I
hereby declare that what I consider to be novel and original, and therefore claim as
secured to me under the Letters Patent hereinbefore in part recited is, the con-
structing machinery or apparatus for rolling iron, steel, or other metal into bars or
plates, substantially as hereinabove described with reference to the accompanying

page_text: Drawings, and particularly the combination with a pair of rolls formed with
annular grooves, recesses, or spaces, of rings or collars fitted truly but loosely on
and able to move lengthwise along said rolls, the ring or collar (or rings or collars)
surrounding one roll working in the groove, recess, or space (or grooves, recesses,
5 or spaces) of the other roll of the pair, substantially as described.
In witness whereof, I, the said Edward Hutchinson, have hereunto set my
hand and seal, this 9th day of December, in the year of our Lord One
thousand eight bundred and seventy nine.
EDWARD HUTCHINSON. (L.S.)
