PROVISIONAL SPECIFICATION.
Improvements in and 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, Black Hill,
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, especially to the class known as universal
mills, or mills in which the sides as well as the upper and lower faces of the material
is passed between rolls; but parts of this invention will apply to other forms of mills.
Furthermore, it comprises improvements upon the invention secured by Letters
Patent No. 16,682, bearing date the 20th day of December 1886, granted to Samuel
Adams; one of the parties to this present application.
In the specification to the before mentioned Letters Patent, there was shown (among
other things), a method of simultaneously adjusting the vertical rolls in parallel
relation to each other, whereby any width of plate, within the capacity of the mill,
could be rolled upon its edges; so as to avoid the necessity of shearing or otherwise
trimming the said edges. This was effected by four right and left hand screws
extending across the width of the mill, (in front and behind the main rolls), and
working in corresponding nuts secured to the bearings of each pair of vertical rolls.
The several screws were revolved by means of a pinion fastened upon one end of each
screw, which pinions were driven by a spur wheel (having an actuating handle),
placed in the centre of, and engaging with, the said pinions. By turning the handle
of the spur wheel in either direction the four right and left hand screws were simul-
taneously turned in their respective nuts, whereby the vertical rolls were simultaneously
advanced towards, or withdrawn from, each other, in exact parallel relation.
The same method was used in relation to the side cheeks or guides, in order to
widen or narrow the space occupied by the plate, beam, or bar in passing through
the rolls.
A part of our present invention consists in dividing the screws, and employing two
or more of them for each vertical roll, so that they no longer extend across the frame
as before stated, to actuate each pair of vertical rolls simultaneously. In the case
now referred to, each vertical roll is advanced or retracted independently of the other,
and requires a separate driving wheel and two or more pinions to work the same, and
these are placed upon the outer faces of the housings of the main rolls. Side cheeks
or guides are made correspondingly adjustable in the same manner, and therefore
need not now be further described.
The independent screws are severally connected to the bearings carrying the
vertical rolls in any suitable manner, so that the rolls are caused to move endways
with the said screws. The latter may be made to revolve within a fixed nut, or the nut
may be caused to revolve while its screw moves end ways only. Consequently, the
pinion is attached to each screw, or each nut, according to the plan adopted; and, in
the latter case, the pinion itself may form the nut: suitable provision being made to
resist the end thrust.
To increase the transverse rigidity required for heavy work, we sometimes place
guide bars across between the framing or housings of the mill, on both faces at the
top and bottom, and adapting the vertical roll bearings to slide between or upon the
said guide bars. We may also use any combination of the before mentioned methods
of supporting and traversing the vertical rolls, and use any number or arrangement
of screws, pinions or gear wheels required for the said purpose. For example we
may use the transverse right and left hand screws (described in the before mentioned
specification), at the top of the mill, and the divided screws, with or without the guide

page_text: bars, at the bottom of the mill. It will be understood that we employ vertical plates,
yokes, or other parts to carry or steady the screws, and wheel work employed. We
may also adapt any of the arrangements made to two or three high mills."
Furthermore, we simplify the adjusting of the bearings of the middle roll in a three
high mill; and strengthen the same by a modification of the wedges and bearings
shown in the said specification. In this case the wedges carrying the screws and
adjusting nuts are made as before, but in screwing them up against the adjoining
wedges that abut upon the boxes which carry the bearings, the adjusting nut acts
upon a flanged extension of the latter wedges, at right angles to the body of the
wedge; the said flanges fitting against the housing. In the flanges are slots, allowing
the wedges to travel inwards against the boxes that carry the bearings, as the screw
wedges are drawn up; while suitable ribs and recesses are arranged upon the boxes
and bearings to prevent any displacement of the latter. We may apply this method
of adjustment to vertical or other rolls employed in other kinds of mills. Instead
of using the screw for fine adjustment beneath the main adjusting screws, (described
in the before named specification), we may employ a pair of reverse wedges with one
or more adjusting screws or nuts, for making the said fine adjustment. We may
also mount one or more indicating drums, or the equivalent thereof, upon the main
adjusting screw or screws, to indicate the space between the main rolls. This
indicating drum may have a thread or helical line cut upon its outer surface to a
regular pitch, and divided by vertical lines, according to any required scale of dimen-
sions, so that by turning the same beside a fixed pointer, the exact space between the
rolls may be readily read off.

Improvements in and 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, Black Hill,
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, especially to that class known as universal
mills, or mills in which the sides, as well as the upper and lower faces of the plate or
other material are subjected to the pressure of rolls during its passage through the
mill; but parts of this invention are applicable to other forms of mills. Furthermore
it comprises improvements upon the invention secured by Letters Patent No. 16,682,
bearing date the 20th day of December, 1886, granted to Samuel Adams, one of the
parties hereto.
In the specification to the before mentioned Letters Patent, there was shown (among
other things), a method of simultaneously adjusting the vertical rolls in parallel
relation to each other, whereby any width of plate within the capacity of the mill
could be rolled upon its edges, so as to avoid the necessity of shearing, or otherwise
trimming the said edges. This was effected by four right and left hand screws
extending transversely across the width of the mill on each side (front and back),
of the main rolls all working in corresponding nuts secured to the bearings of each
pair of vertical rolls. The several screws were rotated by means of a pinion, fastened
upon one end of each screw, gearing into, and driven by a spur wheel (having an
actuating handle), which was centrally placed in relation to the said pinions. By
turning the handle of the spur wheel, in either direction, the four right and left hand
screws were simultaneously turned in their respective nuts, and each pair of vertical
rolls correspondingly advanced towards, or were withdrawn from, each other, in exact
parallel relation.

page_text: The same method was used in relation to the side cheeks or guides, in order to
widen or narrow the space occupied by the plate in passing through the rolls.
In the accompanying drawings, Fig. is an end elevation, Fig. 2, a central
vertical section, and Fig. 3, a front elevation of a plate rolling mill embodying a part
of our present invention. In these figures, A, A are the main rolls, B, B the vortical
rolls, and C, C the frames or housings carrying the rolls. The driving gear for
actuating the vertical rolls is indicated by D, D, but the driving gear of the main
rolls is omitted. The screws are indicated by E, E, and the pinions thereon, and
connecting the same, by F, F. These pinions are arranged as a vertical train of wheels.
In Fig. 3, the screws E, E, are shown as divided, so that each pair of screws is
capable of advancing or withdrawing the vertical roll B, in connection therewith;
independently of any other vertical roll. Each of the upper screws E has a hand
wheel e mounted thereon for driving the same, the rotation thereof being communi-
cated to the corresponding lower screw E by pinions F, F, on each screw, through a
similar pinion free to revolve on a stud f, secured to the housing C. Each screw
pinion is mounted loosely upon the top of the threads of, and rotates with, its
screw E, through the intervention of a feather secured within the bore of the pinion,
which is adapted to slide along a longitudinal slot or keyway el, as the screw travels
endways. A suitably formed nut (shown by dotted lines), is secured within each
housing C, for each screw, consequently, when a handle e is turned in the proper
direction, both upper and lower screws are simultaneously advanced inwardly, carrying
before them the bearings b, b, of the vertical roll B, the driving gear D sliding
with it along the shaft d, and its feather, by the aid of a bracket d' which forms a
double bearing for the bevel wheels D. The abutting ends of the screws E, E, are
formed with a collar fitted into a corresponding recess in each bearing 6 of the vertical
rolls, (as shown by dotted lines in Fig. 3) to retract each roll B, while the pinions F, F
are prevented from end travel by the housing Con one side, and the outer bearing
strap which latter is bolted to the housing.
The side cheeks or guides G, of the plate supporting tables, are correspondingly
adjustable in the same manner, as is shown by the plan view in Fig. 20, (similarly
lettered), but with the outer bearing strap e omitted. In this figure, the hand
wheel e is secured to the shaft, the pinion thereon becoming the driving wheel, and
this pinion can be made to keep the screw pinions in their relative positions by an
enclosing web or guard on each side of the teeth; or other equivalent device for the
purpose may be used.
These independent screws may advance or retract the rolls B or guides G, either
by the rotation of the screw in fixed nuts, or by the rotation of the nuts, while the
screws move end ways only. Consequently, the pinion is attached to each screw,
or each nut, according to the plan adopted; and in the latter case, the pinion
itself may form the nut, (as in Fig. 20); suitable provision being made to resist
the end thrust, in any known manner.
To increase the transverse rigidity required for heavy work, we place guide bars
across between the housings C, C, on both facings of the mill, both top and bottom,
and adapt the vertical roll bearings to slide between or upon the said guide bars,
as shown in Figs. 5, 7, and 8, and in certain detail drawings, hereinafter described.
Fig. 4 is an end elevation, Fig. 7, a front elevation, and Fig. 8, a central
vertical section, of a three high mill, the upper and lower rolls of which are
indicated by the letter A, and the middle roll by A¹. These drawings (with others)
show the application thereto of our independent or divided screw arrangement
which we described in reference to Figs. 1, 2 and 3. In this three high mill
arrangement we bolt guide bars 6, 6, between the housings C, C, across the mill,
before, and behind the main rolls A, A. Upon these we mount the bearings b of
the vertical rolls B in such a manner that they may slide to and fro in accordance
with the end travel of the screws E, E. These screws are actuated simultaneously
by hand wheels e, e, and a irain of toothed wheels or pinions F, F, in the same
manner as already described in reference to the mill shown in Figs. 1, 2 and 3;
but we show four screws and an additional pinion over the former method, to
'

page_text: equalize the strains and resist thrust. The abutting ends of the various screws are
formed as before stated, and engage with a yoke or vertical plate H (shown in
sectional elevation in Fig. 5) their collars fitting into, and engaging with, socket
plates h, h, which are bolted to the yoke H, as shown by Figs. 5 and 7. The
upper part of the yoke H is hollowed out to fit into, and engage with, a bearing
formed on the end of the driving sleeve D, and may be fitted with a suitable bush
or liner. The sleeve revolves with the feathered shaft d on which it is free to
slide endways, and any traversing movement communicated to the yoke H, by the
screws E, will cause a corresponding sliding movement of the sleeve D along the
shaft d. The shaft of each vertical roll B is fitted into a block 6', which is
likewise bolted to the yoke H, and partakes of its movement. This block 6 not
only serves as a bearing for the vertical roll shaft, and (with the yoke and sleeve)
to keep the bevel gears D in their relative positions, but also acts to some extent
as a guide to the plate, or other article passing through the mill to steady
the same from side twisting, until it is fully controlled by its passage through the
end guides G, G, (shown in Fig. 20), when such are used. As a guide the
block 61 is exposed to wear, and may have hardened steel checks replacable for
wear. The block may also be made as a loose collar or roll, free to turn upon
the shaft of the vertical roll B. Either in this case or otherwise, we may prolong
the boxes and bolt them to the yoke H.
Each yoke H, therefore, serves as a movable frame to traverse its connected
vertical roll B, with its bearings d, and driving gear D, to and fro across the
face of the mill, when actuated by the screws E, E. These screws, when actuated
by the hand wheel e, and pinions F, F, turn in nuts (indicated by dotted lines in
Fig. 7) inserted as bushings in the housings C, C; the pinions turning with the
screws, while sliding on the outer diameter thereof, by means of an attached
feather sliding in the key way e¹. The pinions F, F, are kept in their relative
positions by an outer plate e² secured to the housings C, by studs e³. This plate is
shown in elevation in Fig. 6.
The guide bars are secured in right and left hand angle plates 63, 62, which are
bolted to the housings CC, as shown in elevation Fig. 7, in sectional elevation Fig. 8
and by detail drawings, Figs. 8ª, 8b, and 8°.
Figs. 11, 12 and 13, are details of the upper and lower bearings b, b, of the
vertical rolis B shown in the front elevation Fig. 7. These bearings are each
adapted to slide upon the guide bars 6, and consist of a box casting adapted
to carry the two half brasses 63, 63, fitted to the journal of the vertical roll B. One
of the brasses is formed with an extended lug through which the screwed end of
a wedge shaped key 6 passes, and by means of a nut thereon the key is adjust-
able upon the brasses within the box to take up wear.
Fig. 17, is a central vertical section, Fig. 18 an end elevation, and Fig. 19 a front
elevation of a two roll plate mill; in which the transverse movement of the vertical
rolls B, B, is brought about by a combination of the right and left hand screw method,
described in the before mentioned specification of Samuel Adams, and the divided screw
method, described herein. In these figures, a pair of right and left hand screws, E¹, E',
extend between, and through, the housings C, C, working in nuts, forming a part
of the upper bearings b, of the vertical rolls B, B. The divided screws E, E, are
each shown as working in a nut, through the housings C, C, and engaging with
the lower bearings b, b, of the vertical rolls B, B, and which are capable of sliding
upon the slide bars 61, as described for Fig. 7. The screws E and E are caused to
turn by the hand wheels 'e, e, through the intervention of the pinions F, F, in the
imanner described with reference to Figs. 3 and 7. The end thrust upon any of the
pinions F may be taken by an outer plate, or in any other convenient manner.
Figs. 20 and 21 are partial plans of a two roll plate mill, similar to that indicated
by the elevations Figs. 17, 18, and 19. In Fig. 20 is shown the divided or inde-
pendent screw arrangement for actuating the side cheeks or guides G, G, of a
plate supporting table, which has been already described in relation to the adjust-
ment of the vertical rolls, as in Fig. 3. In Fig.-21, two arrangements are shown

page_text: for the adjustment of the side checks or guides G, G. On the upper side of Fig. 21,
the side cheeks G, G, are simultaneously adjusted by a pair of right and left hand
screws 9, 9, as shown in Fig. 2 of the before named specification. In the lower part
of Fig. 21, of the accompanying drawings, however, but one right and left hand
screw g¹ is shown to simultaneously adjust the side cheeks or guides, G G, which
are caused to slide upon two rods or bars, g², g². These bars serve to keep the
faces of the guides G, G, in parallel relation to each other, but it is to be noted
that the divided screw arrangement for working these side cheeks may be used
in the manner indicated by Fig. 20, instead of one or more right and left hand
screws, as shown in the lower part of Fig. 21. If the divided screw arrangement
be used for this purpose, it is sometimes desirable to use one or more rods or
bars g, not only to keep the side cheeks G, G, in parallel relation to each other,
but also to assist in resisting the strain thrown upon them by the passage of the
plate.
Furthermore, we adjust the bearings of the middle roll, in a three high mill,
and strengthen the said bearings, by a modification of the wedges and bearings
shown in the before named specification. Fig. 14 is an inner elevation, Fig. 16
is an outer elevation, and Fig. 15, a plan, (partly in section), of one of the bearings
of the middle roll, in which the wedges a, a, carrying the screws and adjusting
nuts are made as before, but in screwing them up, each wedge abuts upon an
inclined face of each box a¹, employed to carry a half brass for the journal of the
roll. Each box, a', is provided with a flange through which it is secured to the
housing C by bolts a, a, passing through slots in the flange. When the wedges a, a,
are all screwed up, they hold the whole bearing of the middle roll firmly in
position between the opening in the housing (, but by slacking out the wedges a,
on one side, and tightening up those on the other, the end of the roll is given
horizontal adjustment in the required direction, and when this is done, the slack
wedges are screwed up; the slots in the flanges allowing for the required travel'
of the boxes a¹. The boxes a¹, are provided with ribs or projections, as shown in
the sectional plan Fig. 15, which fit directly into correspondingly formed recesses
of the brasses a³, thus dispensing with liners or other parts. By the action of
the wedges a, the wear of the brasses is likewise taken up. The bolts a, tend to
hold the boxes firmly together. The same method of adjustment may be used for
other rolls.
In Figs. 8 and 9 we show elevations, and in Fig. 10 a plan, of a pair of reverse
wedges,, placed beneath each main adjusting screw I of the mill, for fine adjust-
ment. The wedge is provided with a screw at one end, and actuated by a smali
hand wheel working against a bracket secured upon the upper bearing of the
top roll. The wedge i is gained into recesses and projections on the under side of
the upper wedge ³, which, at the top is fitted to receive the main adjusting screw I
in a step bearing. The large screw I is used for coarse adjustment of the main rolls,
the reverse wedges i and are used for fine adjustment by means of the hand wheel
or handle, and the engaging recesses and projections between the two wedges and
the seat of the lower one (as indicated by the detail drawing Fig. 9) prevent side
displacement.
We sometimes mount one or more indicating drums J, upon one or both of the
main adjusting screws I, as shown in Figs. 17 and 19, to indicate the space between
the main rolls, or thickness of the plate to be rolled. The indicating drum J has
a fine thread or helical line cut or traced upon its outer surface to a regular pitch,
and divided by vertical lines according to any required scale of dimensions; so that
by turning the drum J beside a fixed pointer j placed in front thereof, by means
of the handle ', shaft and bevel gears ³, adapted to turn the main adjusting
screws I, I, the exact space between the rolls may be easily read off. It will be
understood that we may variously combine the novel features described herein, and
we may place the connecting pinions and means for resisting thrust, inside the
housings or frames instead of outside, for the transverse adjustment of the vertical
rolls or side cheeks; where it is desirable so to do.
