IMPROVEMENTS IN ROLLING MILLS
Year: 1887

page_text: I GEORGE THOMAS of the firm of George Thomas and Company of 28 Deansgate
Manchester in the County of Lancaster Engineer do hereby declare the nature of said
Invention for IMPROVEMENTS IN ROLLING MILLS, which Invention has been communi-
cated to me from abroad by Carl Ängström of Domnarfvet Sweden Engineer, to be as
follows:-
This invention relates to what are known as universal or Belgian mills i.e. mills in
which both horizontal and edge rolls are employed the former for rolling purposes
and the latter for trimming or cutting the edges of the rolled plate bar or other piece
and the chief object of this Invention is to improve the means for guiding the rolled
piece from the horizontal flattening rolls to the vertical trimming rolls.
In carrying the Invention into effect I place the guides between the two aforesaid
pairs of rolls and I connect the guides to the caps of the top horizontal roll so that
they are moved to correspond with the up or down adjustment of the top horizontal
roll and the guides are also connected to the frames or standards of the edge rolls so
that they are moved horizontally when the edge rolls are adjusted.
In addition to the vertical and horizontal adjustments mentioned the guides are
supported upon an independent bar secured to the cap of the top horizontal roll on
which bar the guides can be set and adjusted independently of one another and of
the rolls and further the guides are so constructed that the rolled piece is held between
their lower sides and the ordinary bottom plates so that the rolled piece is fed into
the nip of the edge rolls and cannot turn up or leave them.
The guides move with the vertical rolls in their motion in or out and are also free
to move in a vertical direction so as to get more or less distance from the bottom
plates entirely independent of the position of or distance between the vertical rolls.

I GEORGE THOMAS of the firm of George Thomas and Company of 28 Deansgate,
Manchester in the County of Lancaster Engineer a communication to me from abroad
by Carl Ängström of Domnarfvet Sweden Engineer 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 what are known as universal or Belgian mills i.e. mills in
which both horizontal and edge rollers are employed the former for rolling purposes
and the latter for trimming or cutting the edges of the rolled plate bar or other piece
and the chief object of this Invention is to improve the means for guiding the rolled
piece from the horizontal flattening rolls to the vertical trimming rolls.
In carrying the Invention into effect I place the guides between the two aforesaid
pairs of rolls and I connect the guides to the caps of the top horizontal roll so that
they are moved to correspond with the up or down adjustment of the top horizontal
roll and the guides are also connected to the frames or standards of the edge rolls so
that they are moved horizontally when the edge rolls are adjusted.
In addition to the vertical and horizontal adjustments mentioned the guides are
supported upon an independent bar secured to the cap of the top horizontal roll on
which bar the guides can be set and adjusted independently of one another and of the
rolls and further the guides are so constructed that the rolled piece is held between
their lower sides and the ordinary bottom plates so that the rolled piece is fed into
the nip of the edge rolls and cannot turn up or leave them.
The guides move with the vertical rolls in their motion in or out and are also free
to move in a vertical direction so as to get more or less distance from the bottom
plates entirely independent of the position of or distance between the vertical rolls.
And in order that this Invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is an elevation partly in section from the sides of the vertical trimming
or edge rolls. Fig. 2 shows a sectional plan of the improved rolling mill. Fig. 3 is
a transverse section of the machine taken between the vertical edge rolls and Fig. 4
is an elevation of the horizontal and vertical rolls with the horizontal rolls set close
together and the vertical rolls a distance apart so as to roll thinner and wider pieces
than when arranged as shown in Fig. 1.
Similar letters refer to similar parts throughout the several views.
In these views.-a a¹ designate the two horizontal rolls of which the top one a¹ is
adjustable vertically to and from the other roll a by means of screws a² and counter
weights not shown. The relative position of this roll a¹ as compared to the roll a
indicates the thickness of the rolled piece. Behind these rolls are mounted the two
vertical trimming or edge rolls bb¹ which can be moved in and out and consequently
regulate the width of the rolled piece. This adjustment is effected by moving the

page_text: roll bearings or beds g g' and along the bars m and n at the top and bottom
respectively by means of the adjusting screws h h¹ and suitable gearing. The vertical
edge rolls are driven by means of bevel gears a horizontal shaft and spur gears
from the roll a and the rolls b b are otherwise so mounted that they may be removed
by simply taking off the caps of the roll bearings and without disturbing the bars m n
upon which the said rolls are supported and adjusted.
The arrangement and shape according to this Invention of the improved guides for
the rolled piece are as follows:-
Two plates or guides e el are placed close to the surface of the vertical edge
rolls bb these plates e e¹ being secured to the upper bearings g g₁ by bolts f which
pass through slots so that the guides e e¹ can slide up and down independently of the
roll bearings g g and thus follow the rolls 66' during adjustment. The guides e e¹
are held at their bottom ends u u¹ by angular arms sliding in slots kk' in the
lower bearings of the rolls b b¹. It will be seen therefore that the guides e e¹
accompanying the vertical edge rolls bb¹ when the latter are moved in and out and
are also free to be moved in a vertical direction so as to get nearer to or farther from
the bottom plates e c' and this entirely independent of the position of or distance
between the vertical rolls 6 61. The guides e e¹ also participate in the vertical move-
ment up or down of the adjustable horizontal roll a' as the fixed brackets p p¹ on the
guides e el are also secured to the bar which moves along with the roll a¹ the bar r
being held at the top bearings ss of the roll a by means of lugs and suitable
bolts. Let it be supposed that the guides e e¹ are so adjusted or fastened to the
horizontal bar that the distance between the lower edges of the guides e e¹ and the
top of the plates c c¹ will be equal to the opening between the horizontal rolls a a
then a piece passing between the horizontal rolls will before entering and while
passing between the vertical rolls be held between the lower edges of the
guides e e¹ and the top of the plates c c and thereby be prevented from turning up or
leaving the vertical rolls. As the ends of the guides e e¹ are liable to become worn
these guides are secured to the barr so that they can be independently adjusted in
a vertical direction. Also the brackets p p on the bar r are each provided with two
adjusting screwed pieces one a hook or angle bolt t acting on the lower side and
the other a set screw 9 on the upper side of the bar see Fig. 3. Through loosening
one and tightening the other of these screwed pieces on one guide e or e¹ this guide
may be adjusted independently of the bar and the distance between the lower edge
of the guides e el and the top of the plates e c¹ always maintained so that the rolled
piece will be completely guided.

Having now particularly described and ascertained the nature of this said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In a universal rolling mill the guides e e¹ placed at the inner side of and close
to the vertical edge rolls b¹ in such a way that the said guides will be at the same
distance from the centre of and move horizontally or in and out with these rolls bb
and at the same time be connected with the adjustable horizontal roll a¹ so as to move
in a vertical direction or up and down with this roll when it is adjusted.
2. The construction combination and arrangement of parts embodying the improve-
ments in rolling mills substantially as herein described and as shown on the Drawings
annexed.
