Improvements in or relating to Rolling Mills.
We, JOHN KAY BEALEY, of St Hilda's Vicarage, Middlesbrough, in the
County of York, Clerk in Holy Orders, and SAMUEL ADAMS, of Castle Side,
Blackhill, in the County of Durham, Rolling Mill Manager, do hereby declare the
nature of this invention to be as follows:-
This invention relates to rolling mills, of various kinds, and it comprises
improvements upon the invention secured by Letters Patent dated the 20th day of
December 1886, No. 16,682, granted to Samuel Adams, one of the parties hereto;
and upon the invention secured by Letters Patent dated the 15th day of October,
1888, No. 14,808, granted to us. The present invention applies to the horizontal
adjustment of the horizontal rolls employed, and to the parts connected therewith.
For the horizontal adjustment of horizontal rolls, we cast or otherwise form holes
in the housings for the reception of bolts or screws, placed in a horizontal position,
and cause the same to act upon the bearing or bearings of each roll it is required to
adjust. The roll bearings are so made and adapted that they are capable of
moving in a horizontal plane at each end of the roll they sustain, the direction of
movement being either right or left of its axis, along a horizontal plane at or about
right angles to the general axis of the roll. By placing one or more bolts, screws,
or rods along this line of movement, for each bearing, and causing the same to act

has been made, the bearing is locked in position by any suitable means, such as by
an opposite screw, wedges, packing, or otherwise.
The bearings are preferably made less in width than the slot in the housings
therefor, and the additional space in the width is only partly taken up by a flanged
or angle plate on each side of the roll bearing. The difference of the space left is
the amount of clearance for the movement of the roll bearing, and this may be
about one eighth of an inch on each side. The angle plates are made to fit against
the inner sides of the slot of the housing, and are bolted to the outer face of the
housings by screw studs and nuts; the studs passing through elongated holes made
in the outwardly placed flange of the angle plates. When a bearing is to be
adjusted, the nuts are slacked upon the studs of the two angle plates, a pushing or
pulling force (or both) is exerted upon the angle plates by the screws passing
through the housings, and this force is exerted upon the bearings. When the
required adjustment has been made, the screws and the nuts are all tightened up,
and any vacant space between the inside of the angle plate and the housing may be
either filled by a wedge, or by suitable packing, or
be left if the bolts or

screws are sufficiently stout to take the side strain. The inner face of the slot of
the housing does not, therefore, require planing.
The method described is applicable to the adjustment of the top and bottom roll
bearings of ordinary mills, and also to the middle roll bearings of three high mills.
In the latter case, however, the bearings are carried in a box composed of one
piece, or of two or more bolted together. This box may be acted upon directly by
the before mentioned adjusting screws, or through the intervention of angle plates,
as already described. The inner end of each of these angle plates is preferably
made to abut against a shoulder either upon a bearing, or upon a box which carries
a bearing, according to the circumstances of the case. By this arrangement, and
by making the slot in the housing for the bearings a little wider than the diameter
of the roll, the latter may be readily removed from the mill by taking the nuts off

page_text: the studs which hold the angle plates to the housing, removing the plates, and
passing the roll out through the slot.

COMPLETE SPECIFICATION.
Improvements in or relating to Rolling Mills.
We, JOHN KAY BEALEY, of S. Hilda's Vicarage, Middlesbrough, in the
County of York, Clerk in Holy Orders, and SAMUEL ADAMS, of Castle Side,
Blackhill, in the County of Durham, Rolling Mill Manager, 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 rolling mills, of various kinds, and it comprises
improvements upon the invention secured by Letters Patent dated the 20th day of
December 1886, No. 16,682, granted to Samuel Adams, one of the parties hereto;
and upon the invention secured by Letters Patent dated the 15th day of October,
1888, No. 14,808, granted to us. The present invention applies to the horizontal
adjustment of the horizontal rolls employed, and to the parts connected therewith.
For the horizontal adjustment of horizontal rolls, we cast or otherwise form holes
in the housings for the reception of bolts or screws, placed in a horizontal position,
and cause the same to act upon the bearing or bearings of each roll it is required
to adjust. The roll bearings are so made and adapted that they are capable of
moving in a horizontal plane at each end of the roll they sustain, the direction of
movement being either right or left of its axis, along a horizontal plane at or about
right angles to the general axis of the roll. By placing one or more bolts, screws,
or rods along this line of movement, for each bearing, and causing the same to act
upon the bearing, either by pushing or pulling-the housing acting as a fulcrum-
the end of the roll and its bearing is shifted in accordance with the actuating force,
along the horizontal plane before mentioned. When the desired adjustment has
been made, the bearing is locked in position by any suitable means, such as by an
opposite screw, wedges, packing, or otherwise.
The bearings are preferably made less in width than the slot in the housings
therefor, and the additional space in the width is only partly taken up by a flanged
or angle plate on each side of the roll bearing. The difference of the space left is
the amount of clearance for the movement of the roll bearing, and this may be
about one eighth of an inch on cach side. The angle plates are made to fit against
the inner sides of the slot of the housing, and are bolted to the outer face of the
housings by screw studs and nuts; the studs passing through elongated holes made
in the outwardly placed flange of the angle plates. When a bearing is to be
adjusted, the nuts are slacked upon the studs of the two angle plates, a pushing or
pulling force (or both) is exerted upon the angle plates by the screws passing
through the housings, and this force is exerted upon the bearing. When the
required adjustment has been made, the screws and the nuts are all tightened up,
and any vacant space between the inside of the angle plate and the housing may be
either filled by a wedge, or by suitable packing, or it may be left if the bolts or
screws are sufficiently stout to take the side strain. The inner face of the slot of
the housing does not, therefore, necessarily require planing.
The method described is applicable to the adjustment of the top and bottom roll
bearings of ordinary mills, and also to the middle roll bearings of three high mills.
In the latter case, however, the bearings are carried in a box composed of one
piece, or of two or more bolted together. This box may be acted upon directly by
the before mentioned adjusting screws, or through the intervention of angle plates,
as already described. The inner end of each of these angle plates is preferably
made to abut against a shoulder either upon a bearing or upon a box which carries

page_text: a bearing, according to the circumstances of the case. By this arrangement, and
by making the slot in the housing for the bearings a little wider than the diameter
of the roll, the latter may be readily removed from the mill by taking the nuts off
the studs which hold the angle plates to the housing, removing the plates, and
passing the roll out through the slot.
In the further description of this invention, reference is made to the accompanying
drawings, in which
Fig. 1 is an outer elevation of a housing for a three high mill, with our improved
adjusting devices applied on the left side to the top and middle roll bearings, while
the same, or similar devices may be placed also on the right side, but are omitted
to save unnecessary drawing. The bottom roll bearing is shown with wedge
adjustments as described in the above named Specification No. 16,682 of 1886.
These wedge adjustments may be used in combination with our improved adjust-
ments described herein.
Figs. 2 and 3 are sectional plans of the top and middle roll bearings shown in
Figs. 1 and 2.
Fig. 4 is an outer elevation of the bottom bearing of a mill, with our improved
adjusting devices applied to the bearing on each side of the housing, and Fig. 5 is a
sectional plan of the same.
Fig. 6 is a similar sectional plan of an adjustment shown on one side only) which
may be applied to either of the roll bearings employed.
The same reference letters are used for the same or equivalent parts throughout.
In Fig. 1 the slot of the housing a carries the top, middle, and bottom rolls b by
their journals c working in their respective bearings d. These bearings are adapted
to slide up or down within the slot of the housing, as usual, in any known manner;
but each bearing is also made and adapted for a small amount of side play-or
horizontal movement at or about right angles to the axial line of the roll working
therein. One or more adjusting screws e, e, are placed horizontally within the
housings, (on each side of the bearings), and by means of a nut f, secured to the
housing a, pressure is exerted upon the bearing d in the said direction. This action
is also indicated in the remaining figures, and the adjusting screw or screws & may
be placed exactly in a line at right angles to the axial line of the roll to be.
adjusted, or upon a plane parallel thereto. The top roll in Fig. 1 has two
screws e, e, placed in the same vertical line, one above the centre of the journal and
the other below; and the same, or a single screw on the central line, may be placed
on the opposite or right hand side of the housing. By slacking out the screw or
screws on the one side, to the required amount, and tightening the other, the
bearing is horizontally adjusted and fixed in the required position. Each of the
screws referred to are actuated by a hand wheel i but other means may be used for
turning the same. A stud is mounted upon the housing to adjust the middle roll
bearing in Fig. 1, between the two screws, e, e, and by means of pinions k, k, secured
thereon and gearing into a toothed wheel on the stud j and turned by the actuating
hand wheel i both screws e, e, are simultaneously operated for the adjustment of the
middle roll bearing. By the same devices on the opposite side, or other equivalent
means described herein, the middle roll bearing is adjusted and fixed in the required
position.
In Fig. 3 the box h carrying the brasses d, is made with internal angle flanges
fitting into a groove or recess in the housing. A thrust plate g is secured on the
end of the screw e so that it may act upon the box h in the required manner, as
shown. The screws e may act directly upon the bearing d, (as shown in Figs. 4
and 5), or upon an external angle or thrust plate 9 which acts directly upon the
bearing, in the manner indicated.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is;
1. The combination of one or more screws with a corresponding nut or nuts,

page_text: secured to the housing, and adapted to bear upon or adjust the bearing of a roll,
substantially as and for the purpose herein described.
2. The combination of a roll bearing or bearing box, adapted to move
horizontally within the slot of a housing, with one or more horizontal adjusting
screws, and means for securing the said bearing or bearing box in position when
adjusted, substantially as and for the purpose herein described.
3. The combination of an adjusting screw, and corresponding nut secured to a
housing, a thrust plate actuated by the said screw, and an adjustable bearing or
bearing box abutting against the said thrust plate, substantially as and for the
purpose described.
4. The devices combinations and arrangements for the horizontal adjustment of
roll bearings, substantially as and for the purpose herein described and shown by
Figs. 1 to 6 inclusive.
