We JOHN OXLEY of 53 Bell Street, Sunderland, in the County of Durham,
Ironworker, ENOCH WARD of Fulwell Road, Sunderland aforesaid, Ironworker,
and WILLIAM OXLEY of Pine Street, Gateshead, in the same County, Ironworker
do hereby declare the nature of our invention for "IMPROVEMENTS IN ROLLING
"
MILLS FOR ROLLING RIVET, BOLT OR OTHER SECTIONS OF IRON AND STEEL to
be as follows:-
Our invention has reference to rolling mills for cold rolling iron and steel and
has for object to improve the quality and finish of rivet, bolt and other rolled
sections.
The improvements essentially consist of the combination in rolling mills of a
pair of horizontal rolls and a pair of vertical rolls so placed relatively to each
other that the bolts or other forms of iron are at one pass acted upon first by the
horizontal rolls and then by the vertical rolls, these 2 pairs of rolls thus con-
stituting what may be termed double action rolls. The horizontal and vertical
rolls are placed between 2 housing frames and are driven by toothed gearing so
arranged by preference that only one roll of each pair is worked by the gearing
the other roll being worked by friction. The vertical rolls can be moved or
adjusted horizontally and vertically to suit any groove in the horizontal rolls.
Our double action rolls above described are intended to form a second rolling
mill train and to be combined with a first train which we prefer to be one con-
sisting of 2 sets of three-high rolls. The piles, blooms or billets are reduced to
the required size by passing and repassing through the first set and are then
brought to the required section by means of the second set of three-high rolls.
After the rolled rods (or other sections) have become sufficiently cool they are
passed once through our double action rolls which scrape off or remove all flaws.
and scale. They thus receive superior finish and having been cold rolled they
possess a better fibre and are able to resist a greater tensile strain. As there is
less passing and repassing than in the ordinary way, the output is increased, less
power is required, and wear and tear of plant is much reduced.

"
Our invention has reference to rolling mills for cold rolling iron and steel and
has for object to improve the quality and finish of rivet, bolt and other rollod
sections.
The improvements essentially consist of the combination in rolling mills of a
pair of horizontal rolls and a pair of vertical rolls so placed relatively to each
other that the bolts or other forms of iron are at one pass acted upon first by the
horizontal rolls and then by the vertical rolls these two pairs of rolls thus con-
stituting what may be termed double action rolls. The horizontal and vertical
rolls are placed between two housing frames and are driven by toothed gearing;
by preference only one roll of the vertical pair is worked by the gearing the other
roll being worked by friction. The vertical rolls can be moved or adjusted
horizontally and vertically to suit any groove in the horizontal rolls; or instead
of being adjustable vertically the vertical rolls can be mounted so as to be readily
removable with the object of substituting vertical rolls with a groove of different
size if required.
Our double action rolls above described are intended to form a second or
finishing or polishing rolling mill train and to be combined with a first train
which we prefer to be one consisting of two sets of three-high rolls of ordinary
construction. The piles, blooms or billets are reduced to the required size by
passing and repassing through the first set and are then brought to the required
section by means of the second set of three-high rolls. After the rolled rods (or
other sections) have become sufficiently cool they are passed through our double
action rolls which scrape off or remove all flaws and scale. They thus receive
superior finish and polish and having been cold rolled they possess a better fibre
and are able to resist a greater tensile strain. As there is less passing and repassing
than in the ordinary way, the output is increased, less power is required, and wear
and tear of plant is much reduced.
In practice we find it of advantage to combine in the same mill train with the
double action rolls, a set of three pairs of rolls the first pair being horizontal, the
second vertical and the third horizontal the set being in fact the same as our
double action rolls before described with the addition of another pair of horizontal
rolls which act upon the rods after they leave the vertical rolls.
The annexed drawings represent a rolling mill constructed in accordance with
our invention. Figure 1 is a front elevation, Figure 2 a plan and Figure 3 an end
elevation. Figure 4 is an end view of the gearing. At the left hand end of the

page_text: train is shown our double action rolls composed of a pair of horizontal rolls A, A
and a pair of vertical rolls B, B; and at the right hand end of the train is a similar
arrangement of horizontal rolls A¹, A¹ and vertical rolls B', B₁ with the addition of
another pair of horizontal rolls C, C at the other side of the vertical rolla. D is the
main shaft of the mill; by means of the wheels E, F, G it drives the shafts H and I;
the spindles of the lower roll of each horizontal pair can be connected by couplings
in the ordinary manner with the shafts D and I. The motion is communicated to
the upper rolls of each horizontal pair by pinions K, K, or these pinions may be
dispensed with and the upper rolls be worked by friction. The wheel E also
drives by means of a wheel L an upper shaft M at each end of which is a bevel
pinion N to drive a corresponding pinion O on the spindle of one roll of each pair
of vertical rolls the other roll of the pair being driven by friction; or the shaft M
wheel L and pinions N and O may be dispensed with, both the rolls of the vertical
pair being in this case driven by the friction of the rod which is forced through
between them by the horizontal rolls. P, P are tubes or guides for conducting the
rods from the horizontal rolls to the vertical rolls. The vertical rolls B, B and
B' B' can be adjusted horizontally in their housing frames Q, Q to bring their
groove or grooves in line with any given groove in the horizontal rolls; this
adjustment is effected by means of the screws R, R; the vertical rolls may also be
similarly adjusted vertically for the like purpose in which case they should have
the same number of grooves as the horizontal rolls but we prefer to make the
vertical rolls removable so that when a groove of different size is required they
may be taken out and replaced by others, in this case each vertical roll will have
only one groove as is seen in the drawings.
When the piles, blooms or billets have been reduced to the required size and
section by means of a first rolling mill train (preferably one consisting of two sets
of three-high rolls as already stated) the rods (or other sections) are allowed to
cool and then passed through the rolls A, A, B, B and afterwards if required through
the rolls A', A¹, B¹, B¹, C₁, C'.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim in respect of rolling mills for rolling rivet, bolt or other sections of iron
and steel is
1. The combination of a pair of horizontal rolls and a pair of vertical rolls so
placed relatively to each other that the bolts or other forms of iron are at one pass
acted upon first by the horizontal rolls and then by the vertical rolls substantially
as hereinbefore described.
2. Constructing rolling mills substantially as hereinbefore described and repre-
sented in the annexed drawings.
