Improvements in Rolling Steel Rails into Angle Section Bars, and
in Rolls therefor.
We, FREDERICK WILLIAM RATCLIFF and JOSEPHI HICKMAN PEARSON, trading.
together as F. W. Ratcliff & Co., of Anchor Iron Works, Oldbury, in the County
of Stafford, Iron and Steel Manufacturers, and PHILIP ROBINSON, of Saint Paul's
Road West Smethwick, aforesaid, Roll Turner, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to the manufacture of rolled steel bedstead and
other angle section bars from old steel rails and rail ends of the usual double
headed section.
In carrying out this invention we pass the rails through holes or gates between
the rolls which are so shaped as to first upset the rail and reduce the depth of
the same but at the same time keep the heads of the rail in line with each other
which is accomplished by the sides of the hole or gate being formed by two deep
collars on one of the rolls between which collars the rail lies and which keep
the heads in line as the web of the rail is thickened and distorted and the depth of
the rail reduced. After being passed through one or more similar holes the
rail is rolled sideways through a hole which is shaped so as to bring the web into
line again and to also gradually reduce the heads and thicken the web the sides
of this hole being similarly formed of deep collars on one of the rolls to keep the
two heads in line. The bar or rail is now passed through another hole or holes
with the axis of what was the web vertical. this hole or each of these holes being
also formed by two deep collars on one of the rolls so as to support the heads
whilst the depth of the bar or rail is being further reduced and the web thickened
until the side grooves between the heads have almost disappeared. The bar is
now rolled into the required finished angle section by being passed through rolls
as commonly used for rolling angle section bars these rolls being shaped so as to
work into one side of the bar which was one of the heads of the rail and groove
the same gradually forcing out the metal so as to fill up the grooves at the sides
of the bar which when the angle section bar is finished have quite or almost dis-
appeared.

in Rolls therefor.
We, FREDERICK WILLIAM RATCLIFF and JOSEPH HICKMAN PEARSON,. trading
together as F. W. Ratcliff & Co.; of Anchor Iron Works, Oldbury, in the County
of Stafford, Iron and Steel Manufacturers, and PHILIP ROBINSON, of Saint Paul's
Road, West Smethwick, aforesaid, Roll Turner, 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 has reference to the manufacture of rolled steel bedstead and
other angle section bars from old steel rails and rail ends of the usual double
headed or bull head section.
In carrying out this invention we pass the rails or rail ends through holes
between the rolls which as hereinafter described are so shaped as to upset the
rail and reduce the depth of the same and at the same time to keep the heads of
the rail in line with each other so that the web is thickened up until the side
grooves between the heads have almost disappeared. The bar in this form is
then passed through rolls which are shaped so as to work into one of those sides
of the bar which was one of the heads of the rail so as to groove the same and
gradually force out the metal sideways and fill up the grooves at the sides of the
bar until when the required angle section bar has been obtained the said side
grooves will have disappeared.
On the accompanying drawings Fig. 1 is a cross section of an ordinary double
headed or bull head rail and Figs. 2, 3, 4, 5, 6, 7, 8, 9, and 10 represent the
cross sections which the bar assumes in the successive stages of rolling the rail
represented by Fig. I into the angle section bar represented by Fig. 10; Fig. 11
shews a modification of the section represented by Fig. 7 and Fig. 12 represents
in longitudinal section a set of rolls marked A B and C shaped in accordance
with this invention for rolling down the rail represented by Fig. 1 to the section
represented in cross section by Fig. 6. This Figure 12 also shews the section
of the bar as it passes through the various holes between the rolls.
The same letters of reference indicate the same parts in all the figures of the
drawings.
In rolling down the rail D represented in cross section by Fig. 1 into the angle
section bar represented by Fig. 10 the rail or rail end is first passed through the.
hole E (see Fig. 12) between the rolls A and B which has the effect of upsetting
the rail and reducing the depth of the same to about the section represented by
Fig. 2 the web being somewhat distorted. The collars 12 of the roll B and
the collars a a² of the roll A keep the heads of the rail in line with each
other. The depth of the rail is now further reduced as shewn by Fig. 3 by pass-
ing the rail through the hole between the rolls B C.the heads of the rail being
kept in line with each other by the deep collars & ² on the roll C. The rail is
now rolled sideways through the hole G between the rolls A and B which as
shewn is so shaped as to bring the web of the rail into line again and 'to' also
gradually reduce the heads and thicken the web so that the bar will now have tlic
appearance represented by Fig. 4. The sides of the hole G are formed with deep
collars b to keep the heads of the rail in line. The bar or rail is now passed
through the hole H between the rolls B and C with the axis of what was the
web vertical this hole H being also formed with deep collars to support
the heads of the rail which will then have the appearance represented by Fig. 5.
The rail or bar is then passed through the hole I which further reduces the

page_text: depth and thickens up the web SO that the rail now has the
appearance about as represented by Fig. 6 this hole I being also formed with two
deep collars b b on the roll B to keep the heads in line. It will be seen by
Fig. 6 that the side grooves d d between the heads of the rail have now been
very much reduced. If a very small section angle bar is required the bar is now
passed through the next smaller hole J so as to further reduce the depth of the
bar and thicken up the web. The bar in the form represented by Fig. 6 is
now rolled into the finished angle section bar by being passed between rolls such
as are commonly used for rolling angle section bars these rolls having holes of
the shapes represented by Figs. 7, 8, 9 and 10 so as to roll the bars to the sections
shewn in these figures. It must be particularly noticed that the bar Fig. 6 has to
be passed through these holes in such a position that the usual collar on one of
them works into one of the sides de ord of the bar (which side was one of the
heads of the rail) so as to form the groove 8 in the same which groove is in the
succeeding holes as shewn by Figs. 8, 9 and 10 widened and enlarged thus
gradually forcing out the metal sideways so as to fill up the grooves at the
sides of the bar so that when the latter has been passed through the last hole and
finished as shewn by Fig. 10 these grooves will have disappeared.
Instead of the bar represented by Fig. 6 being made to assume the section.
represented by Fig. 7 the said bar at this stage may if desired be made to assume
the shape represented by Fig. 11 by passing through a hole of corresponding
shape to Fig. 11 one of the rolls being made with a collar upon it to work into
and form the groove 8 in the side which was one of the heads of the rail.
It will be evident that the number of holes through which the rail is passed,
before it assumes the finished angle section bar may without departing from the
nature of this invention be more or fewer than shewn upon our drawings.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we are, of course, aware
that the process of reducing old double headed or bull headed steel rails and rail
ends to bars of various sections by passing them through a series of holes in rolls,
is not new, and we make no broad claim to such a process, but we declare that
what we claim is:-
1. The manufacture of angle section bars from old double headed or bull headed
steel rails and rail ends by passing the rail or rail ends through consecutive holes
of rolls so shaped as to keep the heads in line and simultaneously reduce the
depth of the rail and thicken up the web and ultimately groove one of the sides
which was one of the rail heads thereby forcing out the metal sideways and filling
up the side grooves of the bar and forming the same into the required angla
section substantially as described and illustrated.
2. In the manufacture of rolled angle section bars from old double headed or
bull headed steel rails and rail ends the employment of rolls grooved so as to form
the consecutive holes E F G H and I for the purpose and substantially as herein-
before described and illustrated by Fig. 12 of the accompanying drawings.
