RICHARD RUSSELL GUBBINS of 17 Park Road New Cross in the County of Kent
Engineer do hereby declare the nature of this invention to be as follows:-
My invention consists in constructing rolls intended for the production of rolled
bars or sheets, so that the dimensions of the "pass" or space between the said rolls
may be altered at pleasure and thus permit "within limits" of any rectangular
section of iron or the like being rolled with the same pair of rolls.
Hitherto one dimension of rolled rectangular iron has been regulated by increasing
or diminishing the distance between the rolls, and this invention has for its object
means for regulating the other dimension.
A pair of plain rolls are mounted in housings and furnished with screws and gearing
for elevating the upper one in any well known manner.
The necks of both rolls are made longer than usual so that each roll is free to slide
endways in its bearings, and on each of them is fitted a strong collar in such manner
that whilst said collars are capable of sliding freely along each roll, they can be
securely made fast at any given point on either of their respective rolls. A groove to
receive these collars is turned in each of the rolls so that each collar, whilst free to
slide on its own roll, is fixed as regards the other one, and the rolls and collars in this
position are put in their places in the housings.
The "pass" or space formed by the two rolls and their collars may be made deeper
or shallower by raising or lowering the top roll, and it may be made wider or
narrower by moving the rolls end wise with regard to one another. The collars are to be
set fast in place when the rolls are in use, but can be released when it is necessary to
alter the width of the "pass."
1 find further advantage in using sliding collars as I can thereby regulate the
pressure on the faces of the " pass so as to keep them perfectly tight and take up

page_text: their wear as needed. This will prevent fins or burrs being formed on the bars rolled
with these rolls.
In some cases I provide the sliding collars with a number of set screws which by
pressing against a stout flange formed on the roll behind the collar gives a very secure
mode of adjusting and fastening the same. In this case one side of the notch in which
the collar runs may be dispensed with and the ends of the rolls formed by the remain-
ing sides are held each to its respective collar by a screw which is carried by a pro-
jection upon one of the neck journals of the upper roll. By these means no matter
where the roll may be in the housing the screw remains in the same place as regards it,
and the requisite end pressure for closing the surfaces of the "
"
pass is always
maintained.

I, RICHARD RUSSELL GUBBINS, of 17 Park Road, New Cross, in the County of
Kent, Engineer" do hereby declare the nature of this invention and in what
manner the saine is to be performed, to be particularly described and ascertained
in and by the following statement:-

My invention consists in constructing rolls intended for the production of rolled
bars or sheets, so that the dimensions of the " pass or space between the said
rolls may be altered at pleasure and thus permit "within limits any rectangular
section of iron or the like being rolled with the same pair of rolls.

Hitherto one dimension of rolled rectangular iron has been regulated by increasing
or diminishing the distance between the rolls, and this invention has for its object
means for regulating the other dimension.
A pair of plain rolls are mounted in housings and furnished with screws and gearing
for elevating the upper one in any well known manner.
The necks of both rolls are made longer than usual so that each roll is free to
slide endways in its bearings, and on each of them is fitted a strong collar in such
manner that whilst the said collars are capable of sliding freely along each roll ;
they can be securely made fast at any given point on either of their respective
rolls.
•
A groove to receive these collars is turned in each of the rolls so that each collar
whilst free to slide on its own roll, is fixed as regards the other one, and the rolls and
collars in this position are put in their places in the housings.
The "
"3
pass or space formed by the two rolls, and their collars may be made deeper
or shallower by raising or lowering the top roll, and it may be made wider or narrower
by moving the rolls endwise with regard to one another.
The collars are to be set fast in place when the rolls are in use, but can be released
when it is necessary to alter the width of the "pass."
"
I find further advantage in using sliding collars as I can thereby regulate the
pressure on the faces of the "pass so as to keep them perfectly tight and take up
their wear as needed. This will prevent fins or burrs being formed on the bars rolled
with these rolls.
In some cases I provide the sliding collars with a number of set screws which by
pressing against a stout flange formed on the roll behind the collar gives a very secure
mode of adjustment and fastening the same. In this case one side of the notch
which the collar runs may be dispensed with and the ends of the rolls formed by the
remaining sides are held each to its respective collar by a screw which is carried by a
projection upon one of the neck journals of the upper roll.
By these means no matter where the roll may be in the housing the screw remains
in the same place as regards it, and the requisite end pressure for closing the surfaces
of the "pass" is always maintained.

escribe the accompanying drawings thereof, reference being had to letters and
gures marked thereon.

22
Having now fully described the nature and object of my invention, and the
manner in which the same is to be performed, I claim as new and novel the following:
First. The combination of the machine constructed with rolls intended for the pro-
duction of rolled bars or sheets, so that the dimensions of the " pass or space
between the said rolls may be altered at pleasure, and permit of any rectangular
section of iron or the like being rolled with the same pair of rolls, substantially herein
described and according to the accompanying drawings.
Secondly. I claim the advantage of regulating the dimensions, by raising or
lowering the top roll substantially herein described and according to the accom-
panying drawings.
Thirdly. I claim the advantage of the sliding collars, thereby regulating the
pressure on the faces of the "
pass" so as to keep them perfectly tight, substantially
herein described.
Fourthly. The iron bars formed or rolled with these rolls are not subject to any
burrs or fins left on the edges, substantially subscribed.
