Improvements in and Apparatus for the Manufacture of Iron or
Steel Plates with Ribs or Projections thereon.
I, JOHN DEVONSHIRE ELLIS of the Atlas Steel and Iron Works, Sheffield in the
County of York, Ironmaster do hereby declare the nature of my said Invention to be
as follows:-
My Invention relates to the manufacture of steel and iron plates with convex or
other form of ribs or projections on one side and plane or concave or other form on
the opposite side, the said ribs or projections running lengthwise of the plates and
being principally applicable for use in the construction of furnaces or fire boxes or of
flues for Steam Boilers or for other analogous purposes.
According to my Invention I prepare ingots, slabs or blooms with or without ribs
or projections to suit the section to be produced by the Rolls, the said ingots slabs or
blooms being made of a length corresponding to the width of the finished plate.
The ribs or projections may be cast on the ingot for rolling direct into plates, or
the ingots with cast ribs or projections may be reduced in thickness under a hammer
or forging press, or from ordinary plain ingots, the slabs may be made with or without
ribs or projections, as may be preferred by planing, cogging in rolls or forging in
a press.
After being so prepared the steel or iron slabs or blooms are rolled in rolls with
grooves or preferably with grooves and collars.
I place a horizontal guard at each side of the rolls, which by suitable gearing can
be raised or lowered as required for the purpose of preventing the plate from either
buckling or moving laterally.
To effect the latter object, ribs or guides are placed upon the guards which
correspond in shape and size to the hollows rolled in the plate, thus when the guards
are brought down to the plate during the process of rolling the ribs of the guard by
fitting the hollows in the plate prevent the lateral movement aforesaid. The gearing
for raising or lowering these guards may be worked by hand, steam or hydraulic
power.

I JOHN DEVONSHIRE ELLIS of the Atlas Steel and Iron Works Sheffield in the
County of York 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 :-
My Invention relates to the manufacture of Steel and Iron plates with convex or
other form of ribs or projections on one side and plain or concave or other form on
the opposite side the said ribs or projections running lengthwise of the plates and
being principally applicable for use in the construction of furnaces or fire boxes or
of flues for steam boilers or for other analogous purposes.
According to my Invention I prepare ingots slabs or blooms with or without ribs
or projections to suit the section to be produced by the rolls the said ingots slabs or
blooms being made of a length corresponding to the width of the finished plate. The
ribs or projections may be cast on the ingot for rolling into plates direct or the ingots
with or without cast ribs or projections may be reduced in thickness under a hammer
or forging press or by planing or by cogging in rolls.
After being so prepared the steel or iron slabs or blooms are rolled in rolls with
grooves and collars as illustrated in the accompanying Drawings. Figure 1 of which
is a front view. Figure 2 a plan with the rolls removed and Figure 3 an end view of
apparatus for performing this Invention.
The collars which are used with the rolls are shewn at X X in Figures 1 and 3.
They are applied to each end of one of the rolls and overlap the other of the rolls.
I place a horizontal guard CC at each side of the rolls Y which can be raised or
lowered as required. For the purpose of preventing the plate from either buckling
or moving laterally ribs or guides are placed or formed upon the guards CC which
ribs or guides correspond in shape and size to the hollows rolled in the plate thus
when the guards are brought down to the plate during the process of rolling, the ribs
of the guard, by fitting the hollows in the plate, prevent the lateral movement of the
plate. The gearing for raising or lowering these guards may be worked by hand
steam or hydraulic power. As illustrated in the drawing the guards are each
guided in grooves in the roll framing and are carried by uprights B passing through
guiding brackets b on the roll framing and provided at their upper ends with
screws on which work internally screwed wheels Z formed with worm teeth on their
peripheries with which engage worms a on the shafts A mounted on brackets and
worked by hand wheels as shewn.

page_text: Having now particularly described and ascertained the nature of said Invention
my
and in what manner the same is to be performed I declare that what I claim is :-
First The manufacture of steel or iron plates with ribs or projections thereon by
preparing the slabs or blooms from Ingots as before described and rolling such slabs
or blooms in grooved and collared rolls.
Second-The combination with rolls for rolling steel or iron plates as described of
a ribbed guard at each side of the rolls in the manner described to prevent the
buckling or lateral movement of the plates being rolled substantially as described and
illustrated.
