IMPROVEMENTS IN MACHINERY FOR ROLLING STEEL AND IRON to be as follows:-
Year: 1885

page_text: We THOMAS BROWN of Belvidere Road Walsall in the County of Stafford
Machinist and JOSEPH GORDON GORDON of Landore Steel Works Landore in
the County of Glamorgan Steel Manufacturer do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN MACHINERY FOR ROLLING STEEL AND IRON
to be as follows:-
--
"
Our invention consists of the construction and combination hereinafter described
of the parts of rolling machinery principally applicable for blooming or cogging
and slabbing and finishing masses of steel and iron the object of our said invention
being to effect the said operations in a more efficient and economical manner than
is effected by the use of the rolling machinery ordinarily employed.
The principal part of our invention consists in the combination of a pair of
horizontal rolls and a pair of vertical rolls each pair of rolls having a reversing
motion by means of which reversible pairs of rolls in conjunction with the
mechanical appliances herein-after described an ingot or bloom can be rolled to
any required thickness or width without the necessity of removing the said ingot
or bloom from one groove to another or having to turn the ingot or bloom on its
edge for reducing its width.
We arrange one pair of the reversible rolls in front of the other pair of rolls
the two pairs of rolls being mounted and geared in the same or in separate standards
the horizontal pair of rolls being used to reduce the thickness of the ingot or bloom
and the vertical pair of rolls being used for reducing or regulating the width of
the ingot or bloom. The said reversible rolls are made capable of adjustment so
that the ingot or bloom can in conjunction with the reversing motion of the rolls
be passed backwards and forwards through the same groove or portion of the rolls
any number of times. For this purpose the horizontal rolls are capable of
advancing to and receding from one another and similarly the vertical rolls (or
one of them) have an advancing and receding motion to and from one another.
After the ingot or bloom has been passed through both pairs of rolls the rolls of
one or both pairs are brought closer together for the further reduction of the
bloom in width and thickness. The motions of both pairs of rolls are then
reversed and the ingot or bloom returned through the same groove or portion
of the rolls and so on until the article under operation has been reduced to the
required size and shape,

page_text: We make by preference both rolls of each pair capable of receding from and
approaching one another whereby the rolls can be opened out to an extent
sufficient to take a large ingot or bloom with less rise and fall from the centre
line of the pinions and the consequent preservation of the wabblers of the rolls
from injury than when one roll only is capable of adjustment.
Instead of reversing both the horizontal and the vertical pairs of rolls as described
one pair only of the rolls may be made capable of reversal. In this case the
unreversible pair of rolls is opened out to facilitate the passage of the ingot or
bloom into the other or reversible pair of rolls after which both pairs of rolls are
brought closer together and the one pair of rolls again reversed so as to return
the ingot or bloom through the rolls the operations described being repeated as
required.
We drive one or both of the vertical rolls by bevil gearing which sliding on
feather keys causes the driving bevil wheels to travel with the moveable roll or
rolls. We open and close the rolls by means of screw gearing carried by the
standards so that the whole of the mechanism is carried by the same framing.
The rolls may be adjusted by screws wedges or otherwise instead of by the
gearing described.
In order to compress steel ingots and steel and iron blooms at their ends as well
as at their sides and edges the vertical rolls may be made to open sufficiently wide
to permit the ingot or bloom to pass completely through thein to obtain end
compression by means of a steam or hydraulic press which may be combined with
the two pairs of rolls. When we use the vertical rolls for this purpose a turn
table is placed in front of them so as to permit the ingot or bloom to be easily and
quickly turned after the ends have been compressed.
In working our new or improved machinery for slabbing and blooming masses
of iron and steel we proceed as follows:-
The horizontal and vertical rolls are opened out to receive the ingot or bloom
and the said ingot or bloom having been passed through both pairs of rolls the
rolls of one or both pairs are brought closer together for further reducing the ingot
or bloom. The motion of the rolls is then reversed and the ingot or bloom returned
through the rolls without the necessity of carrying the bloom from one groove to
another groove and in this way the rolling operation is repeated as many times as
is required to obtain a bloom or article of the desired size and shape.
When only one pair of the rolls is made reversible the last pair or unreversible
rolls through which the bloom is passed is opened out to facilitate the return
passage of the bloom into the pair of reversible rolls when the latter rolls have been
brought closer together and their motion reversed as before described.
Dated this eleventh day of December 1885.

We THOMAS BROWN of Belvidere Road Walsall in the County of Stafford
Machinist and JOSEPH GORDON GORDON of Landore Steel Works Landore in the
County of Glamorgan Steel Manufacturer do hereby declare the nature of the said
Invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our invention consists of the construction and combination hereinafter described
of the parts of rolling machinery principally applicable for blooming or cogging
and slabbing and finishing masses of steel and iron the object of our said invention
being to effect the said operations in a more efficient and economical manner than
is effected by the use of the rolling machinery ordinarily employed.
The principal part of our invention consists in the combination of a pair of
horizontal rolls with a pair of vertical rolls each pair of rolls having a reversing
motion by means of which reversible pairs of rolls in conjunction with the
mechanical appliances hereinafter described an ingot or bloom can be rolled to
any required thickness or width without the necessity of removing the said ingot
or bloom from one groove to another or having to turn the ingot or bloom on its
edge for reducing its width.
We arrange one pair of the reversible rolls in frout of the other pair of rolls the
two pairs of rolls being mounted and geared in the same or in separate standards
the horizontal pair of rolls being used to reduce the thickness of the ingot or bloom
and the vertical pair of rolls being used for reducing or regulating the width of the
ingot or bloom. The said reversible rolls are made capable of adjustment so that
the ingot or bloom can in conjunction with the reversing motion of the rolls be
passed backwards and forwards through the same groove or portion of the rolls
any number of times. For this purpose the horizontal rolls are capable of
advancing to and receding from one another and similarly the vertical rolls (or
one of them) have an advancing and receding motion to and from one another.
After the ingot or bloom has been passed through both pairs of rolls the rolls of
one or both pairs are brought closer together for the further reduction of the bloom
in width or thickness or both in width and thickness. The motions of both paira
of rolls are then reversed and the ingot or bloom returned through the same groove
or portion of the rolls and so on until the article under operation has been reduced
to the required size and shape.
We make by preference both rolls of each pair capable of receding from and
approaching one another whereby the rolls can be opened out to an extent sufficient
to take a large ingot or bloom with less rise and fall from the centre line of the
pinions and the consequent preservation of the wabblers of the rolls from injury
than when one roll only is capable of adjustment. Instead of reversing both the
horizontal and the vertical pairs of rolls as described one pair only of the rolls may
be made capable of reversal. In this case the unreversible pair of rolls is opened
out when the bloom is travelling in a direction contrary to that in which the
acting parts of the said unreversible rolls are travelling to facilitate the passage of

page_text: the ingot or bloom into the other or reversible pair of rolls the said bloom not
being acted upon by the opened out rolls after which the opened out rolls are
brought closer together so as to act upon the bloom and the one pair of reversible
rolls again reversed so as to return the ingot or bloom through the rolls both pairs
of rolls now acting upon it the operations described being repeated as required.
We drive one or both of the vertical rolls by bevil gearing which sliding on
feather keys causes the driving bevil wheels to travel with the moveable roll or
rolls. We open and close the rolls by means of screw gearing carried by the
standards so that the whole of the mechanism is carried by the same framing.
The rolls may be adjusted by screws wedges or otherwise instead of by the
gearing described.
In order to compress steel ingots and steel and iron blooms at their ends as well
as at their sides and edges the vertical rolls may be made to open sufficiently wide
to permit the ingot or bloom to pass completely through them to obtain end com-
pression by means of a steam or hydraulic press which may be combined with the
two pairs of rolls. When we use the vertical rolls for this purpose a turn table is
placed in front of them so as to permit the ingot or bloom to be easily and quickly
turned after the ends have been compressed.
In working our new or improved machinery for slabbing and blooming masses
of iron and steel we proceed as follows-
The horizontal and vertical rolls are opened out to receive the ingot or bloom
and the said ingot or bloom having been passed through both pairs of rolls the
rolls of one or both pairs are brought closer together for further reducing the ingot
or bloom in one or both directions. The motion of the rolls is then reversed and
the ingot or bloom returned through the rolls without the necessity of carrying the
bloom from one groove to another groove and in this way the rolling operation is
repeated as many times as is required to obtain a bloom or article of the desired
size and shape.
When only one pair of the rolls is made reversible the other pair or unreversible
rolls through which the bloom is passed is opened out to facilitate the return
passage of the bloom into the pair of reversible rolls when the latter rolls have
been brought closer together and their motion reversed as before described. In
this arrangement the ingot or bloom is operated upon by both pairs of rolls when
it is passed through them in one direction and is operated upon by one pair of
rolls only in its return passage through the rolls. By reversible rolls we wish it
to be understood that we mean rolls so geared and driven that the direction of
their rotation may be changed at pleasure that is the rolls can be rotated for
carrying the ingot or bloom through the rolls in one direction and the direction of
their rotation reversed for returning the ingot or bloom through the said rolls in
the opposite direction.
Although machinery constructed according to our invention is principally
applicable to the blooming or cogging and slabbing and finishing of masses of steel
and iron yet it may also be applied to the rolling and reducing of ingots and bars
of steel or iron for various other purposes.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that we
claim as our invention of "Improvements in machinery for rolling steel and iron
"
First Combining or arranging in the manner described a pair of horizontal
rolls with a pair of vertical rolls both pairs of rolls having a reversing motion the
rolls of each pair being capable of adjustment nearer to or further from one
another whereby the ingot bloom mass or bar of steel or iron can be passed back-
wards and forwards any number of times through the same groove or portion of
the rolls without the necessity of removing the ingot bloom mass or bar from one
groove to another or having to turn the ingot bloom mass or bar on its edge for
reducing its width substantially as herein before described.

page_text: Secondly-Making only the horizontal pair of rolls or the vertical pair of rolls
of the combined pairs of rolls reversible as herein described and opening out the
unreversible pair of rolls for facilitating the return passage of the ingot bloom
mass or bar into the other or reversible pair of rolls substantially as herein before
described.
Thirdly The combination with the pairs of horizontal and vertical rolls of
either of the kinds claimed in claims 1 and 2 of a steam or hydraulic press for
compressing the ingot bloom mass or bar on its ends substantially as herein before
described.
