PROVISIONAL SPECIFICATION.
Improvements in or connected with Rolling Mills.
I ISAAC HAYWARD, of 123 Lovely Lane, Warrington, in the County of
Lancaster, Wire Roller, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or connected with rolling mills, and
more particularly refers to mills employed for rolling wire rods.
Its primary object is to provide improved means whereby the heavy manual
labour now exercised in the early stages of such rolling, or what is known as the
bolting down train,-is nearly if not entirely obviated, also that two or more rods
may be simultaneously treated, and in which special provision is made whereby the
overlapping of the wire, from the delivery to the next take up hole, is disposed of,
and further provision whereby the finished wire rod is coiled as it leaves the
rolls &c.
As will be already imagined this my invention admits of considerable variation
in detail without departing from its nature.
A mill constructed after this my invention, consists as follows:-
1 provide that the bolting rolls shall consist of the required number, which in
ordinary wire rod rolling I find eight pairs to answer very well. These rolls are
all horizontal and placed one pair in front of the other, so that as the rod billet
passes from the first pair, it may pass into the second, and thence straight on to
the third and so on. These rolls are placed at a suitable distance apart to accom-
modate the necessary guides &c., between them. Usually the first pair of rolls.
have square or diamond like grooves therein, and the second pair of rolls have oval
grooves, and so on alternately throughout. The billet is passed into the first pair,
say a square or similar groove, and conveyed thence by ordinary guide direct into
the next pair of rolls having an oval groove. From the oval it is further conveyed
to the next square by a guide which is so constructed, that the said rod is turned
around to the extent of 90 degrees, and in such position presented to the said
square groove. These alternate operations are repeated throughout the bolting
train. The successive rolls are driven by suitable gearing and at suitable speeds.
It is however only during the early treatment of the billet, that is, while it is.
comparatively large in section that this continuous rolling, by the turning up
guides can be effected, but by the said number of pairs of rolls, the rod is con-
siderably reduced without the aid of manual labour and yet by a simple arrangement
of machinery.
From the bolting rolls, the rod now passes forward to the finishing rolls, which
in themselves are arranged much in the ordinary manner, and generally of what is.
known as the single train type. In this part of the mill however, I make special
provision for the conveyance in some cases, of the rod from one pair of rolls to the
next. As will be readily understood by reason of the reduction of sectional area,.
the rod is delivered from the rolls in greater length (or speed) than received, hence
the next roll has to be increased in diameter or speed, or a combination of both to
accommodate this. This is not easy to perfectly effect, hence at times the second.
pair of rolls may not take it up sufficiently fast, and consequently there would be
an accumulation between the two rolls, which would prove troublesome. To
obviate this, I provide the following mechanism :-I provide the usual short
length of exit guide. Adjoining this provide a movable guide, that is, a guide ur

page_text: tube through which the rod passes, and which by suitable mechanism may be
raised or lowered at the will of the attendant, from any suitable point where the
attendant may be.situated. Following this lifting device the rod is passed through
a channelled guide which is open upon its upper side for a given distance and
closed for the rest of the way, and which may be in one continuous tube, but
preferably consists of two parts of about equal length, which facilitates construction
and adjustment and also provides means of readily getting rid of the oxides formed
upon the metal.
These guides are usually placed between the squares and ovals,
and are suitably curved or shaped so as to convey the rod from the one pair of rolls
to the others. Thus when the attendant is aware that the accumulation of delivery
is exceeding the take up, he can lift the said rod out of the channel, so as to afford
it plenty of room for freedom from entanglement while it is still being taken up
by the succeeding rolls. The rod having passed through to the last pair of finishing
rolls it is now coiled as follows:-As it leaves the rolls it is conveyed along a
tubular or a gutter like guide into a revolving receiver or winder, which consists
of a tube anglewise to the axis of revolution, that is, its entrance is central whilst
its outer end describes a circle of a more or less diameter, which may in some cases
be adjusted according to the size of coil desired. In front of this revolving winder
is a drum of more or less taper shape on to which the rod is wound. This drum
may be single, but preferably I mount two (or more) of such drums upon a
revolving frame carried upon a stand so that when the rod is wound upon the one,
it may be quickly turned out of the way for removal purposes and at the same
time another is presented ready for the next rod. Suitable driving gear and other
required mechanism is adopted for driving the winder and operating the drum or
drums as may be required.

I ISAAC HAYWARD, of 123 Lovely Lane, Warrington, in the County of
Lancaster, Wire Roller, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in or connected with rolling mills, and
specially suitable for mills employed for rolling wire rods, but which may be used
for other sections.
Its primary object is to provide improved means whereby the heavy manual
labour now exercised in the early stages of such rolling, or what is known as
the bolting down train,-is nearly if not entirely obviated, also that two or more
rods may be simultaneously treated, and in which special provision is made whereby
the overlapping of the wire, from the delivery to the next take up hole is
disposed of.
As will be already imagined this my invention admits of considerable variation
in detail without departing from its nature.
In order to more clearly describe and explain this my invention, I have appended
hereunto illustrative sheets of drawings, upon which are figures and numbers of
reference, similar uumbers referring throughout the several views to the same
thing or part.
Fig. 1, shows a general plan view of the invention.
Fig. 2, shows a detail plan view of the mechanism for preventing the over-
lapping of the wire in its course from one set of rolls to the next.
Fig. 3, is a side view of this overlapping preventative mechanism.

page_text: The driving mechanism may be varied, but that shown commends itself in
which 6, is the main engine shaft, upon which is the rope or band pulley 7, which
drives on to the pulley 8, upon countershaft 9, upon which latter are pulleys 10-
& 11, driving on to pulleys 12 & 13 respectively at different speeds. Upon or
connected to shaft 9, is the gear wheel 14, which drives wheel 15, on shaft 16, this
again carrying wheel 17, which drives wheel 18. Concurrent with the wheel 14,
is also the wheel 19, which again drives the wheel 20. In a similar manner the
wheel 13, on shaft 21, concurrently drives the wheels 22 and 23, the wheel 22,
driving the wheel 24, and this again through the wheel 25, drives the wheel 26;
while the wheel 23 drives the wheel 27. By varying the diameters of these several
wheels and pulleys, the desired various speeds may be attained in the usual manner.
28, 29, 30, 31, 32, 33, 34 & 35, are the bolting rolls, which may be increased or
diminished in number if required, but for wire rod rolling, I find this number to.
answer well. These rolls are all horizontal and placed one pair in front of the
other, so that as the rod billet, indicated by dotted line 36, passes from the first
pair 28, it may pass into the second, and thence straight on to the third, and so on..
These rolls are placed at a suitable distance apart to accommodate the usual
necessary guides &c., between them. Usually the first pair of rolls have square
or diamond like grooves therein, and the second pair of rolls have oval grooves,.
and so on alternately throughout. The billet is passed into the first pair, say a
square or similar groove, and conveyed thence by ordinary guide direct into the
next pair of rolls having an oval groove. From the oval it is further conveyed to
the next square by a guide which is so constructed, that the said rod is turned
around to the extent of 90 degrees, and in such position presented to the said
square groove. Such guides are already in use. These alternate operations are
repeated throughout the bolting train, that is, as far as rolls 35. The successive.
rolls are driven by suitable gearing and at suitable speeds, as for instance, it will
be seen that the rolls 29, 31, 33, & 35, are driven faster than their respective.
preceding rolls, in order to take up the draft or increased speed of output. It is
however only during the early treatment of the billet, that is, while it is com-
paratively large in section that this continuous rolling, by the turning up guides
can be effected, but by the said number of pairs of rolls, the rod is considerably
reduced without the aid of manual labour and yet by a simple arrangement of
machinery.
From the bolting rolls, the rod now passes forward to the finishing rolls 37, 38,
39, 40 & 41, which in themselves are arranged much in the ordinary manner, and
generally of what is known as the single train type but which may if desired be
of the double train type. In this part of the mill however, I make special
provision for the conveyance in some cases, of the rod from one pair of rolls to the
next. As already intimated it will be readily understood by reason of the
reduction of sectional area, the rod is delivered from the rolls in greater length (or
speed) than received, hence the next roli has to be increased in diameter or speed,.
or a combination of both to accommodate this. This is not easy to perfectly
effect, particularly in the finishing rolls, hence at times the second pair of rolls.
may not take it up sufficiently fast, and consequently there would be an accumula-
tion between the two rolls, which would prove troublesome. To obviate this, I
provide the following mechanism, which is shown in enlarged detail in Figs. 2
& 3. I provide the usual short length of exit guide 42. Adjoining this I provide
a movable guide 43, that is, a guide or tube through which the rod passes, and
which by suitable mechanism such as by carrying the guide in lever 44, pivoted
at 45, and operated by handle rod 46, the front end 47, of the guide may be raised
or lowered at the will of the attendant, from any suitable point where the attendant
may be situated. Following this lifting device the rod is passed through a
channelled guide 48, which is open upon its upper side at 49, for a given distance
and closed at 50, for the rest of the way, such guide may be in one continuous
tube, from the guide 47, to the next entrance guide 51, but preferably it consists
of two parts 48 & 52, of about equal length, which facilitates construction and also

page_text: •
provides means at their junction at 53, of readily getting rid of the oxides formed
upon the metal. These guides are usually placed between the squares and ovals,
and are suitably curved or shaped so as to convey the rod from the one pair of
rolls to the others. Thus when the attendant is aware that the accumulation of
delivery is exceeding the take up, or what is sometimes termed overlapping he
can lift the said rod out of the channel, 48, as indicated by dotted line 54, so as to
afford it plenty of room for freedom from entanglement while it is still being taken
up by the succeeding rolls.
This arrangement of mechanism for lifting the guides such as 43, may be con-
siderably varied in detail, inasmuch as mills varying in character and dimensions
may require such variation.
Taking therefore the course of a wire rod billet to explain the action of this my
invention (although I do not confine its action hereby to such rods) it will be seen
that the billet (as it is termed in the early stages) passes through the rolls 28
to 35, and thence it is turned by hand into the rolls 37 (the rod as it is now termed)
thence passing automatically through the guides 48 & 52 &c. into rolls 38, then
passed on by hand into rolls 39 and so on..
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In rolling mills the combination with the finishing rolls-such as those shown
at 37 to 41-of a continuous train of rolls-such as those shown at 28 to 35-and
operating substantially as herein described and shown upon the drawings.
2. In rolling mills the combination with rolls such as 37 and 38, and guides 42,
and guides or channels 48 and 52, of the movable guide 43, lifter or lever 44, and
handle 46, constructed and operating substantially as described and shown upon
the drawings.
3. The general combination and arrangement of bolting rolls, and finishing rolls,
with their respective guides and gearing, substantially as herein described and
illustrated upon the drawings.
