page_text: LETTERS PATENT to Isaac Hayward, of Warrington, in the County
of Lancaster, Wiro Roller, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR ROLLING WIDE, RODS, HOOPS, OR OTHER SECTIONS OF
METAL,"
Sealed the 9th September 1878, and dated tho 11th March 1878.

PROVISIONAL SPECIFICATION left by the said Isaac Hayward at
the Office of the Commissioners of Patents, with his Petition, on
the 11th March 1878.
I, ISAAC HAYWARD, of Warrington, in the County of Lancaster,
Wire Roller, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR ROLLING WIRE, RODS, HOOPS, OR OTHER
SECTIONS OF METAL," to be as follows :—
My Invention consists in an arrangement of double trains of rolls
of such varied sizes that the second pair are made of such a diameter
as to take up the full amount of the firsts delivery without alteration of
.speeds.
-

page_text: I place my trains in line with each other at any convenient or
required distance apart. I pass the bar or billet from the furnace
through the first pair of rolls, and from thence along a trough or
guide (or other equivalent) to a second pair in the other train, the
diameter of which rolls are sufficient to take up the delivery without 5
alteration of speed. The bar is now passed through a third pair of
rolls in this same train, from thence through a trough or guide, same
as before, to a fourth pair of rolls in the first train, and from thence
through the same rolls again, and after leaving the fourth rolls a
second time it will pass through a similar double set (or round) to 1
the front of first train, and again through another and as many as
the nature and size of the work may require, the take-up being effected
by the increased size of rolls, instead of altering of speeds; thus, the
wear on the rolls is equal, and it will take less power to drive, with a
less number of attendants, besides doing considerably more work in the 1
same time.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Isaac Hayward in the Great Seal Patent Office on
the 11th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Isaao i
HAYWARD, of Warrington, in the County of Lancaster, Wire Roller,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of March, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Isaac Hayward, Her special license that I,
tho said Isaac Hayward, my executors, administrators, and assigns, or
such others as I, the said Isaac Hayward, my executors, administrators,
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 MACHINERY FOR ROLLING
WIRE, RODS, HOOPS, OR OTHER SECTIONS OF METAL," upon the condition

page_text: (amongst others) that I, the said Isaac Hayward, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to
5 bo 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 Lotters Patent.
NOW KNOW YE, that I, the said Isaac Hayward, do hereby declaro
the nature of my said Invention, and in what manner the same is to
O be performed, to be particularly described and ascertained in and by tho
following statement, reference being had to the Figures on the accom-
panying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say) :-
My Invention consists in improved arrangements and combinations
5 of double trains of rolls for the purpose of enabling a second pair of
rolls throughout the entire series to take up the full amount of a
previous delivery without any alteration in the speeds of the shafts
in a more efficient manner than has hitherto been attained.
I place the trains opposito each other at any convenient or required
) distance apart, and cause all the shafts to revolve at the same speed
by means of ordinary toothed wheels or goaring, the taking-up being
effected by rolls of larger diameters and greater surface speeds than the
rolls which deliver the metal to them, there being guides or troughs
to lead the metal to the rolls, and also from ono pair of rolls to another,
and it will be found that with my improved arrangement of trains thero
is less wear and tear of the rolls, less power required to drive them, a
fowor number of workman wanted, and considerably more work pro-
duced in the same time than in any other arrangement of trains having
rolls of different surface speeds.
On the accompanying Sheet of Drawings Fig. 1 is a plan of one
of my improved arrangements of double trains adapted for rolling wiro;
Figs. 2 and 3, longitudinal elovations of the trains detached; Fig. 4,
an end elevation of the trains combined; Fig. 5, an end view of the
large gearing for driving the trains; and Figs. 6, 7, and 8 are enlarged
views of the guides or troughs detached.
The driving shafts a, b, of the two trains A, B, are turned at the
same speed by the larger toothed wheels c. d. and the smaller ones e. f.

page_text: both pairs being in equal proportions, and the various pairs of smaller
and larger rolls in the double trains are geared together by toothed
wheels or pinions 9 having diameters corresponding with those of the
rolls, and in the smaller rolls the grooves are rectangular, and in the
larger ones curved, and each of the two first pairs of rolls in cach train
are connected together by a single coupling h.
The guides for leading the metal to the rolls and guiding it from
them are composed of open and tubular parts, the open parts leading
to the rolls, and the tubular parts guiding from them, and all the
guides are carried by cross bars adjusted and fixed in slots in the
pedestals carrying the rolls, and in the various Figures the open
parts of the guides are marked i, k, the tubular parts 1, and the
cross bars m. When the metal is properly heated and revolving motion
given to the two trains of rolls, a bar or billet is taken from the
furnace and passed into the guide i and through the grooves n in
the smaller rolls o of the first train A, from whenco it passes through
the tubular part 7 and the open part k to the grooves in the larger
rolls p in the second train B, the surface motion of the rolls p being
sufficient to take up and draw out the full amount delivered by the
rolls o. The metal is now passed into another open guide i and
through the grooves in the smaller rolls in the second train B,
and guided to grooves in the larger rolls in the first train A, the
surface speed of the rolls & also being sufficient to take up and draw
out the metal delivered by the rolls r, and then the metal is passed
through other grooves in the rolls o, p, and r, s, and also through:
grooves in the rolls t, u, v, w, x, and y, and finally delivered in a
finished state from the rolls z, and in all cases the larger rolls take up
and draw out what has been delivered by the smaller.
In Fig. 1 the course of the metal is shewn by the dotted lines and
arrows, but it is evident that the number of rolls and the course of the
metal can be varied to a great extent, as the metal can be passed
continuously between successive pairs of rolls, or between different
grooves in the same pairs of rolls, the grooves in all cases being formed
of the shapes required to draw wire, rods, hoop iron, or other sections
of metal.

page_text: proportion may be varied as desired, according to the sizes and arcas
of the sections of metal. By this arrangement of a double train of
rolls in a series an oval, diamond, or rectangular form can be produced
on cach side of the outlet of the double train, and thus there is no necd
cither of a curved or spiral guide, both of which are great hindrances
in practical working, and it will be found that by the working of this
arrangement the size of the iron or steel will be doubly reduced each
time it is put in by hand, and also that one man can do the work of two,
and that much longer rods of common iron can be rolled than by any
other method.
Having now described the nature and particulars of my said In-
vention, and the manner in which the same is to be performed, I
desire it to be understood that in machinery for rolling wire, rods,
or other sections of metal, I claim the improved arrangement and
combination of double trains of rolls, as shewn and described, or any
mero modification thereof for the purpose of enabling rolls of varied
diameters, or having different surface speeds to be used with greater
efficiency and economy than has hitherto been attained.
In witness whereof, I, the said Isaac Hayward, have hereunto set
my hand and seal, the Ninth day of September, in the year of
our Lord One thousand eight hundred and soventy-three.
