Improvements in and connected with Three-high Universal Rolling
Mills.
I, JAMES RILEY, General Manager, to the Steel Company of Scotland, Limited, of
23 Royal Exchange Square, Glasgow, in the County of Lanark, North Britain, do
hereby declare the nature of this invention to be as follows, that is to say :-
My said Invention has for its object to improve the construction and operation of
three-high universal rolling mills.
In carrying out my Invention I arrange in combination with three horizontal rolls,
and in a special manner, two pairs of vertical rolls to operate on the edges of the slabs
or plates passed through the mill. The vertical rolls are adjustable in position by
gearing arranged to act equally in inward and outward directions on all the vertical
rolls, and also simultaneously and equally on longitudinal lateral guides or fences
which prevent the slab or plate from deviating from its proper course.
For moving
the slab or plate to and from the rolls two long tables are employed, one extending
from each side of the machine, and each fitted with a number of driven rollers, whilst
hydraulic apparatus is used for raising and lowering the inner ends of the tables so as
to pass the slab or plate in between the middle and top roll or in between the middle
and bottom roll.
The bottom roll is at each end held by a bottom and two lateral bearing brasses, the
latter being adjustable by means of vertical wedges arranged to be moved downwards
by means of screws fixed in parts of the housings. The middle roll is at each end held
in bearings the parts of which are contained in a skeleton box arranged to slide up and
down in the slot of the housings, but fitted with slide plates to bear and move on the
sides of the slot or on plates affixed thereto. Brasses bear on the sides of each journal
and horizontal wedges adjustable by means of screw nuts bearing on the outer faces
of the brasses and box are interposed between them and the slide plates. The inner
sides of the bearing boxes are made with consoles to support the cramp bars upon
which the usual guards are fixed for guiding the slab or plate as it is just entering
between and leaving the rolls; and similar guards are fixed to one of the cramp
bars and directed downwards towards the underside of the middle roll to prevent
a slab or plate from turning up when leaving the middle and lower roll. The
middle roll is raised and lowered by means of hydraulic cylinders arranged out-
side of the upper parts of the housings, with their rams issuing upwards. Cross-
heads are fixed to the rams and each is by two rods connected to a bearing
block supporting the outer end of the roll journal, the journals being suitably
prolonged for the purpose.
The top roll is at each end held in a bearing the parts of which are contained
in a skeleton box fitted with slide plates to move on the sides of the housing
slot or on plates affixed thereto. There are four bearing brasses, upper, lower, and
two lateral, the last being adjustable by vertical wedges placed between them
and the slide plates with their smaller ends uppermost, and with screwed ends
and nuts for drawing them up to tighten or adjust the brasses. As in some
existing mills a short equalising screw is interposed between the bearing and the
main screw. The main screw spindles for depressing the top roll have fixed on their
upper ends spurwheels gearing with an intermediate spurwheel carried by a plate or
frame which rises with the screw spindles, and one spurwheel gears with a pinion
carried by the same frame and which moves along a vertical shaft with which it
engages by a groove and key, the vertical shaft being driven through gearing from a
steam engine. The top roll is lifted by means of hydraulic cylinders placed beneath
the housings and arranged to act on bars which extend up to the top bearings at the
sides of the housing slots. The bearing boxes are prevented from moving outwards

page_text: from the housings by keeper bars of T section fitted to grooves in the sides of the
housing slots.
There are four vertical rolls all carried similarly by yokes or frames arranged to be
movable inwards and outwards. The acting parts of two of the vertical rolls are
arranged to act on a slab or plate as it leaves the bottom and middle rolls; and the
acting parts of the other two vertical rolls are arranged to act on the slab or plate as
it leaves the middle and top rolls, and the vertical rolls may be distinguished as the
lower and upper pairs. The yokes or frames of the upper vertical rolls have fixed to
their lower parts short lateral guides or fences which are in continuation of guides or
fences carried by the feeding tables, and these guides or fences are adjusted to project
less inwards than the lower rolls to an extent equal to the draft or amount of action
which the lower rolls are designed to effect on the edges of the slab or plate.
Similarly, corresponding short lateral guides or fences are fixed to the upper parts of
the yokes or frames of the lower vertical rolls and are set less inwards than the upper
rolls. The surface speed of the vertical rolls is made the same as that of the horizontal
rolls and as each pair of vertical rolls acts on the slab or plate as it is issuing from the
horizontal rolls it will be obvious that they must bear on the edges of the slab or plate
with a rolling contact and pressure without rubbing friction.
and
The vertical rolls are driven by transverse horizontal shafts situated above them and
acting through bevil wheels. Each driving bevil wheel on a horizontal shaft is
movable along the shaft and receives its motion by means of a groove and key;
it is formed with an elongated tubular boss having on it a groove collar into the
groove of which fits a fork on the upper end of the yoke or frame carrying the vertical
roll, the yoke thereby carrying the driving bevil wheel along with it and
keeping it in gear with the bevil wheel fixed on the upper end of the vertical
roll.
The feeding tables are carried by trunnions at their outer ends and near their
inner ends are connected by rods to levers on rocking shafts below. Each rocking
shaft has on it a two-armed lever, one arm having a counterweight suspended
from it, and the other arm being connected by a rod to a crosshead, to which
both rocking-shaft levers are similarly connected, and which is itself connected by
side rods to a crosshead fixed to the ram of a horizontal hydraulic cylinder. In
consequence of the size of this cylinder and the weight and motion of the moving
parts it is necessary to adopt special means to prevent injurious concussive action
when the direction of the motion of the water which operates in the cylinder is
changed. The main body of the ram is connected by a central spindle and cross
ribs with a cylindrical shell fitting the inside of the cylinder and provided to
cover the main port by which the water enters and leaves the cylinder. This
port is, at its opening into the cylinder, of a long narrow shape, the middle being
the widest part, and the width tapering to points at each end. As the ram when
raising the feed tables, approaches the outer end of its stroke the shell attached
to it gradually covers the port and shuts off the water by diminishing degrees so
as to avoid shock. And in a similar way, when the return movement takes place,
the shell in receding again very gradually uncovers the port. In addition to the
main port there are two small ports one with a valve opening outwards against
a spring and the other with a valve opening inwards against a spring and
both communicating with the main passage; and the main passage also
communicates with a relief valve loaded with a spring and which yields on
any sudden excess of pressure occurring in the pipes. At the closed end of the
hydraulic cylinder a spring buffer is arranged to act as a stop to the ram, the
crosshead to which the side rods from the ram are connected coming in contact
with the buffer when the ram is at the outer end of its stroke.
The rollers of the feed tables consist by preference each of a set of thick disks
formed or fixed on a shaft. They are. driven by gearing, being arranged in sets
of four or five, those of each set having on them spur pinions in gear with inter-
inediate spur pinions, and each set deriving its motions through bevil wheels from
a longitudinal shaft which is carried and moves with the table and is driven by

page_text: suitable gearing from other shafts actuated by a steam engine. At their inner
ends each is continued in a narrower part with shorter rollers, such narrower
parts projecting in between the vertical rolls when these are in there innermost
positions and serving to feed a slab or plate close up to the horizontal rolls.
The feed tables carry longitudinal lateral guides or fences which are movable
inwards and outwards by gearing driven along with that which similarly moves the
vertical rolls. The gearing acting immediately on these fences has to accommodate
itself to the up and down movements of the feed tables. For this purpose, in each
case, a stationary horizontal shaft, by bevil wheels drives a tubular shaft which turns
on a central spindle fitted with an eye at its lower end on the horizontal shaft. The
tubular shaft has on it an upper bevil wheel fitted to slide along it and turned by it by
means of a groove and key; and this upper bevil wheel being held in a swivelling
bracket attached to the table drives a bevil wheel forming part of the fence gearing
on the table.

COMPLETE SPECIFICATION.
Improvements in and connected with Three-high Universal Rolling
Mills.
I, JAMES RILEY, General Manager to The Steel Company of Scotland, Limited, of
23 Royal Exchange Square, Glasgow, in the County of Lanark, North Britain, 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, that is to say :-
My said Invention has for its object to improve the construction and operation of
three-bigh universal rolling mills.
In carrying out my Invention I arrange in combination with three horizontal
rolls, and in a special manner, two pairs of vertical rolls to operate on the edges of
the slabs or plates passed through the mill. The vertical rolls are adjustable in
position by gearing arranged to act equally 'in inward and outward directions on all
the vertical rolls, and also simultaneously and equally on longitudinal lateral guides
or fences, which prevent the slab or plate from deviating from its proper course.
For moving the slab or plate to and from the rolls, two long feeding tables are
employed, one extending from each side of the machine, and each fitted with a
number of driven rollers; whilst hydraulic apparatus is used for raising and lowering
the inner ends of the feeding tables so as to pass the slab or plate in between the
middle and top roll or in between the middle and bottom roll.
And in order that my said Invention and the manner of performing the same
may be properly understood, 1 hereunto append six sheets of explanatory drawings
to be hereinafter referred to and representing the various arrangements and con-
structive details constituting my improvements.
Figure, 1, on sheet, 1, of the drawings is a plan showing a large portion of a
complete rolling mill with its accessories. Figure, 2, sheet, 2, is a sectional side
elevation; and figure, 3, sheet, 3, is a transverse-sectional elevation, both corre-
sponding to figure, 1. Figures, 4, to 13, sheet 4, are enlarged views of details
appertaining to the main or horizontal rolls. Figures 14, 15, and 16, sheet, 5, are
enlarged views of one of the vertical rolls with parts carrying and driving it.
Figures, 17, 18, and 19, sheet, 6, are views of the hydraulic apparatus for moving
the feeding tables; and figures, 20, 21, and 22, sheet, 6, are views showing parts for
adjusting fences or lateral guides on the feeding tables. In these drawings the
same reference letters, numerals, and their combinations, are used to mark the same
or like parts wherever they are repeated.
Parts of the machinery not hereinafter referred to, or in respect of which no claim
is made may be constructed according to any suitable plan which is already in use
or known.

page_text: The bottom horizontal roll, A, (figures, 2, to 7) is at each end held by a bottom
bearing brass, A 1, and lateral bearing brasses, A 2, the latter being adjustable by
means of vertical wedges, A 3, arranged to be moved downwards by means of
screws, A4, fixed in parts of the housings, H. The middle horizontal roll, B,
(figures, 2, to 4, and 11 to 13) is at each end held in bearings the parts of which are
contained in a skeleton box, B 1, arranged to slide up and down in the slot of the
housings, H, but fitted with side plates, B2, to bear and move on the sides of the
slots or on plates affixed thereto. Brasses, B 3, bear on the sides of each journal,
and horizontal wedges, B4, adjustable by means of screw nuts bearing on the outer
faces of the brasses and box are interposed between them and the slide plates, B 2.
The inner sides of the bearing boxes, B 1, are made with consoles, B 5, to support
the cramp bars, D, upon which the usual guards, D 1, are fixed for guiding the
slab or plate as it is just entering between and leaving the rolls; and similar
guards, D2, are fixed to one of the cramp bars, D, and directed downwards towards
the under side of the middle roll, B, to prevent a slab or plate from turning up
when leaving the middle and lower rolls, B, A. The middle roll, B, is raised and
lowered by means of hydraulic cylinders, E, arranged outside of the upper parts of
the housings, H, with their rams issuing upwards. Crossheads, E 1, are fixed to the
rams, and each is by two rods, E 2, connected to a bearing block, E 3, supporting
the outer end of the journal of the roll, B, the journals being suitably prolonged for
the purpose. These parts are shown in plan in figure, 13.
The top horizontal roll, C, (figures, 2, to 4, and 8 to 10) is at each end held in a
bearing the parts of which are contained in a skeleton box, C1, fitted with slide
plates, C2, to move on the sides of the housing slot or on plates affixed thereto.
There are, for each journal, four bearing brasses, upper, C3, lower, C4, and two
lateral, C5, the last being adjustable by vertical wedges, C6, placed between them
and the slide plates, C2, with their smaller ends uppermost, and with screwed ends
and nuts for drawing them up to tighten or adjust the brasses. As in some existing
mills a short equalizing screw, F 1, is interposed between the bearing and the main
screw, F. The main screw spindles, F, for depressing the top roll, C, have fixed on
their upper ends spurwheels, F 2, gearing with an intermediate spurwheel, F 3,
carried by a plate or frame, F 4, which rises with the screw spindles, F; and one
spurwheel, F2, gears with a pinion, F 5, carried by the same frame, F4, and which
moves along a vertical shaft, F 6, with which it engages by a groove and key, the
vertical shaft, F 6, being driver by bevil wheels, F7, from a shaft, F 8, having on
it a pulley, F 9, for a driving belt from a steam engine. By means of a worm on
the shaft, F 8, and a wormwheel on the spindle of an index, 1, the position of the
rolls is shown on a large scale on a dial, 12. The top roll, C, is lifted by means of
bydraulic cylinders, G, placed beneath the housings, H, and arranged to act on
bars, G 1, which extend up to the top bearings, C1, at the sides of the housing slots.
These bars, G 1, are fixed to crossheads, G 2, formed on the cylinders, G, which are
movable, their rams being stationary and fixed by means of crossheads or plates, G 3,
and rods, G 4, to the bottoms of the housings, H. The bearing boxes, B 1, and C1,
are prevented from moving outwards from the housings, H, by T-section keeper
bars, H 3, fitted to grooves in the sides of the housing slots.
There are four vertical rolls, J, (figures, 1, to 3, and 14 to 16) all carried similarly
by yokes or frames, J1, arranged to be movable inwards and outwards. The
acting parts, J 2, of two of the vertical rolls are arranged to act on a slab or plate
as it leaves the bottom and middle horizontal rolls, A, B ; and the acting parts, J2,
of the other two vertical rolls are arranged to act on the slab or plate as it leaves the
middle and top rolls, B, C, and the vertical rolls, J, may be distinguished as the
lower and upper pairs. The yokes or frames, J1, of the lower vertical rolls,
(figures 14 to 16) have fixed to their upper parts short lateral guides or fences, K,
which are in continuation of guides or fences, K 1, (figures, 20 to 22) carried by the
feeding tables; and these guides or fences, K, are adjusted to project less inwards
than the acting parts, 2, of the other. pair of vertical rolls, to an extent equal to
the draft or amount of action which the rolls are designed to effect on the edges of

page_text: the slab or plate. Similarly corresponding short lateral guides or fences, K, are
fixed to the lower parts of the yokes or frames, J 1; of the other or upper vertical
rolls, and are set less inwards than the acting parts, J 2, of the lower vertical rolls.
The surface speed of the vertical rolls, J, is made the same as that of the horizontal
rolls, A, B, C, and as each pair of vertical rolls acts on the slab or plate as it is
issuing from the horizontal rolls it will be obvious that they must bear on the edges
of the slab or plate with a rolling contact and pressure without rubbing friction.
The vertical rolls, J, are driven by transverse horizontal shafts, L. situated above
them, and acting through bevil wheels, L 1. Each driving bevil wheel, L1, on a
shaft, L, is movable along the shaft, and receives its motion by means of a groove
and key; and it is formed with an elongated tubular boss, L 2, having on it a groove
collar, L3, into the groove of which fits a fork, L4, on the upper end of the yoke
or frame, J1, carrying the vertical roll, the yoke thereby moving the driving
wheel, L1, along the shaft, L, and keeping it in gear with the bevil wheel fixed on
the upper end of the vertical roll, J. The yokes, J 1, of the vertical rolls, J, are
fitted to slide on upper and lower pairs of transverse horizontal guide bars, J 3, J 4,
fixed to the housings, H; and they are moved or adjusted inwards and outwards on
the guide bars by means of screw spindles, J 5, made with enlarged ends or collars,
fitted into sockets in the outer sides of the yokes, in which sockets they are held
so as to be free to turn by rings, J 6, bolted to the yokes. The screw spindles, J 5,
work in internally screwed bushes fixed in sockets in the housings, but not shown,
and they are made with longitudinal grooves (cutting across the screw threads) to
engage with keys formed or fixed in the eyes of spurwheels, J 7, which turn with
the spindles. There are four vertical sets of the spurwheels, J 7, one for each
vertical roll, J, there being in each set four of which one is an intermediate spur-
wheel on a stud; and each set of spurwheels, J7, is held in position close to the
outside of the housings, H, by a plate, J 8. The lowest of each set of spurwheels, J 7,
receives its motion from the lowest of the set of screw spindles, J 5, and the spur-
wheels, J7, communicate the motion to the higher screw spindles, J 5. Each lowest
screw spindle, J 5, receives its motion by means of a square shaft, J 9, coupled to its
end, and extending through the squared eye of a spurwheel, M, carried between a
frame, M1, and a plate, M 2. Each spurwheel, M, is driven by a pinion, M 3, on a
short shaft driven by bevil wheels, M 4, from two longitudinal shafts, M 5, geared by
bevil wheels, M 6, to a transverse shaft, M 7. One of the longitudinal shafts, M 5, is
driven in any convenient way by a steam engine, which is not shown.
The feeding tables, N, consisting mainly of long side plates suitable connected
transversely, and carrying a number of rollers, R, are carried by means of
trunnions, N 1, at their outer ends; and near their inner ends are connected by
prods, N 2, to levers, N 3, on rocking shafts, N 4, carried in bearings below. Each
rocking shaft, N 4, has on it a two-armed lever, N 5, one arm having a counter-
weight, N 6, suspended from it, and the other arm being connected by a rod, N 7, to
a crosshead, N 8, to which the rocking-shaft levers, N 5, for both feed tables, are
similarly connected, and which is itself connected by side rods, N 9, to a crosshead
fixed to the ram, P, of a horizontal hydraulic cylinder, P 1, figures; 2, and 17 to 20.
In consequence of the size of this cylinder, P 1, and the weight and motion of the
moving parts, is necessary to adopt special means to prevent injurious concussive
action when the direction of the motion of the water which operates in the cylinder is
changed. The main body of the ram, P, is connected by a central spindle and cross
ribs, P2, with a cylindrical shell, P 3, fitting the inside of the cylinder, and provided
to cover the main port, P 4, by which the water enters and leaves the cylinder. This
port, P 4, is at its opening into the cylinder, of a long narrow shape, the middle being
the widest part and the width tapering to points at each end. As the ram, P, when
raising the feed tables, N, approaches the outer end of its stroke, the shell, P 3,
attached to it gradually covers the port, P 4, and shuts off the water by diminishing
degrees so as to avoid shock. And in a similar way, when the return movement takes
place, the shell, P3, in receding, again very gradually ancovers the port. In addition
to the main port, P 4, there are two small ports, one, P 5, with a valve opening

page_text: outwards against a spring, and, the other, P 6, with a valve opening inwards against a
spring, and both communicating with the main passage, P7; and the main passage
also communicates with a relief valve or plunger, P 8, loaded with a spring an I which
yields on any sudden excess of pressure occurring in the pipes. At the closed end of
the bydraulic cylinder, P1, a spring buffer, P9, is arranged to act as a stop to the
ram, P, the crosshead, N 8, to which the side rods, N 9, from the ram are connected
coming in contact with the buffer, P 9, when the ram, P, is at the outer end of its
stroke.
The rollers, R, of the feed tables, N, consist, by preference, and as shown, each of
a set of thick disks formed or fixed on a shaft. They are driven by gearing, being
arranged in sets of four or five, and having on them spur pinions, R 1,. those of each
set being in gear with intermediate spur pinions, R2, and each set deriving its
motions through bevil wheels, R 3, from a longitudinal shaft, R 4, which is carried by
and moves with the table, N, and is driven by suitable gearing from other shafts
driven by a steam engine. Near the middle of the length of each feed table, N, there
is a transverse horizontal shaft, S, which has on it a pinion, R 5, gearing with an
intermediate spurwheel, R 6, indicated by a dotted circle in figure, 2, and carried at
the middle joint of a pair of links, R 7, of which one outer end is centered on the
driving shaft, S, the other being centered on a shaft, R 8, having on it one of the
intermediate pinions, R2, and geared by bevil wheels, R3, to the longitudinal
shaft, R 4, carried by the feed table. The links, R 7, accommodate themselves to the
rising and falling of the feed table and keep the intermediate spurwheel, R 6, in gear
with the pinion, R 5, on the driving shaft, S, and also in gear with a pinion on the
shaft, R 8, of the feed table. The transverse driving shaft, S, is geared by bevil
wheels, S1, to a longitudinal shaft, S2, extended sufficiently for driving the roller
gearing of both feed tables, N; and this shaft, S 2, is itself geared by spurwheels, S 3,
to the crank shaft, S 4, of a steam engine partly shown in figure, 1.
At its inner end, each feed tube, N, is continued in a narrower part, with shorter
rollers, R9, the two narrower parts of the feed tables projecting in between the
vertical rolls, J, when these are in their innermost positions, and serving to feed a slab
or plate or receive it close up to the horizontal rolls, A, B, C.
The feed tables, N, carry longitudinal lateral guides or fences, K 1, figures, 1, 2,
20, 21, and 22, which are movable inwards and outwards by gearing driven along
with that which similarly moves the vertical rolls, J, and is hereinbefore described.
The gearing acting immediately on the table fences, K 1, has to accommodate itself to
the up and down movements of the feed tables. N, and an arrangement for this
purpose is shown in figures, 1, to 3, and 20, to 22. One of the longitudinal shafts, M 5,
herein before referred to as driven by a steam engine and as part of the gearing for
moving the vertical rolls, J, inwards and outwards drives by bevil wheels, M 6,
and T, two transverse shafts, T 1, and M 7, each of which by bevil wheels, T2, drives
a tubular shaft, T 3, which turns on a central spindle, T4, fitted with a cross eye at its
lower end on the horizontal shaft, T 1, or M 7. The tubular shaft, T 3, has on it an
upper bevil wheel, T 5, fitted to slide along it and turned by it by means of a groove
and key; and this upper bevil wheel, T 5, being held in a swivelling bracket, T 6,
attached to the table, N, drives a bevil wheel, T 7, forming part of the fence gearing
on the table. This gearing consists, in the case of each fence, K 1, of two screw
spindles, K 2, fixed to the fence, and extending through internally screwed bosses, of
two spurwheels, K3, which gear with a spurwheel, K4, on a shaft, K 5, having on it
the driven bevil wheel, T 7. This shaft, K 5, extends across a framing, K 6, carrying
the fences, Kil, and their gearing and fixed upon the inner end of each feed table, N.
The wheels, K3, K4, are at one side kept in position by a plate, K 7, and at the
other side by a bracket, K. 8.
The main gearing for driving the horizontal rolls, A, B, C, may be arranged in any
suitable known manner. As shown (in figures, 1, and 3) it comprises additional
parts for actuating the gearing herein before described for driving the vertical rolls, J.
The main housings, H, are carried upon a pair of transverse girders, H 1, which are
extended sufficiently to also carry the frame pieces, M 1, and at one side far enough

page_text: to carry a pair of housings, H 2, containing the primary main gearing. This gearing
consists of a middle spurwheel, V 1, on a short shaft, V, driven by a steam engine
which is not shown. The spurwheel, V, gears with lower and upper spurwheels, V2, V3.
on short shafts, V 4, V 5, which actuate the lowest and highest borizontal rolls, A, C,
through the usual "breaking" spindles which are not shown.
On the upper
shaft, V 5, there is a spurwheel, V 6, which gears with two spurwheels, V 7, on the
transverse horizontal shafts, L, hereinbefore described as for driving the vertical
rolls, J.
As hereinbefore indicated steam engines are employed for actuating the various
combinations of gearing; and the various movements are brought about as required
by manipulating the valve gear of such engines and the valves of the hydraulic
cylinders, E, G, and P 1. The hand levers for acting on the various valves may be
arranged in any convenient way; they are, however, by preference placed near
together and so that the operator or operators attending to them have fully in view
the parts of the machinery controlled by them.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of parts constituting as a whole the improved three-high
universal rolling mill and accessories, substantially as herein before described and as
shown in the accompanying drawings.
2. The improved combination of parts composing the bearings for the bottom
horizontal roll substantially as herein before described and as shown in the accompany-
ing drawings.
3. The improved combination of parts composing the bearings for the middle
horizontal roll substantially as hereinbefore described and as shown in the accompany-
ing drawings.
4. The improved arrangement of the middle horizontal roll, with its cramp bars,
and guards, and with the appliances for raising it, substantially as hereinbefore
described and as shown in the accompanying drawings.
5. The improved combination of parts composing the bearings of the top horizontal
roll, substantially as hereinbefore described and as shown in the accompanying
drawings.
6. The improved construction and arrangement of the vertical rolls, their acting
parts being such as to operate only on a slab or plate when it is issuing from between
the horizontal rolls, and there being directly combined with the rolls lateral guides or
fences set wider apart, to the extent of the draft, than the parts of the rolls in concert
with which they respectively act substantially as hereinbefore described.
7. The improved combination of parts carrying, guiding, driving and adjusting the
vertical rolls substantially as hereinbefore described.
8. The improved construction and arrangement of the feeding tables with
narrowed inner ends extending in between the vertical rolls, substantially as herein-
before described.
9. The arrangement of the lateral guides or fences on the feeding tables, in
combination with the gearing by which they are all adjusted inwards and outwards in
concert with the vertical rolls, and which is contrived to accommodate the up and
down movements of the inner ends of the feed tables substantially as hereinbefore
described.
10. The improved construction of the hydraulic cylinder and ram with inlet port
and relief valve details for moving the feed tables substantially as hereinbefore
described.
