PROVISIONAL SPECIFICATION:
Improvements in Rolling Flat Bars of Iron or Steel, and in Rolls to be
used for that purpose.
We, JABEZ LONES and EDWARD HOLDEN, trading as Lones, Vernon and Holden,
of Sandwell Iron and Axle Works, Smethwick, in the County of Stafford, Manu-
facturers, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to produce by the rolling process, flat bars of
iron or steel without. burr or fin and having in cross section the figure of a practi-
cally, perfect rectangle, that is, a bar having its faces accurately parallel to one
another and its edges at right angles thereto. This object we attain. by the
combination of rolling processes hereinafter described in conjunction with the
special construction of grooved rolls also hereinafter described..
In carrying our invention into effect we take a heated billet of iron or steel
and roll it in ordinary grooved rolls.until it is reduced to a bar square in cross section
and of a size suitable for the production of a flat ban of the kind hereinafter
described. We take this: square bar and pass it between flat grooved rolls
of the ordinary kind and thereby roll it into a flat har having a thickness and width
equal or nearly equal to that of the finished flat bar to be produced. This flat
bar is next passed between a pair of specially constructed rolls having flat grooves
arranged diagonally..or inclined, some of the angles of the grooves being slightly
flattened.
These rolls are worked in the ordinary way, that is, the bar is introduced into
the groove at. the front of the rolls and the rolled.bar, is; delivered from the rolls
at the back thereof. By passing the partly formed flat bar. between the diagonal
or inclined grooves of the last mentioned pair of rolls, the figure of one of the
flat faces of the bar is squared or perfected. The flat bar thus rolled is then
passed between a nearly similar pair of finishing grooved rolls but the flat grooves
are inclined in the opposite direction and their angles are without flats.
.
By the action, of these finishing rolls. the other face of the bar is squared or
perfected and the edges of the bar also squared, that is, rolled at right angles
to the parallel sides or faces of the bar. A flat.bar. of iron or steel. without burr
or fin and having, its, sides squared, that is, its adjacent sides perfectly at right.
angles is. produced..

We, JABEZ LONES and EDWARD HOLDEN, trading as Lones, Vernon and Holden.
of Sandwell Tron and Axle Works, Smethwick, in the County of Stafford, Manu-

page_text: facturers, do hereby declare the nature of our invention and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
The object of our invention is to produce by the rolling process, flat bars of
iron or steel without burr or fin and having in cross section the figure of a practi-
cally perfect rectangle, that is, a bar having its faces accurately parallel to one
another and its edges at right angles thereto. This object we attain by the
combination of rolling processes hereinafter described in conjunction with the
special construction of grooved rolls also hereinafter described.
In carrying our invention into effect we take a heated billet of iron or steel
and roll it in ordinary grooved rolls until it is reduced to a bar square in cross section
and of a size suitable for the production of a flat bar of the kind hereinafter
described. We take this square bar and pass it between flat grooved rolls.
and thereby roll it into a flat bar having a thickness and width
equal or nearly equal to that of the finished flat bar to be produced. This flat
bar is next passed between a pair of specially constructed rolls having flat grooves
arranged diagonally or inclined, some of the angles of the grooves being slightly
flattened.
These rolls are worked in the ordinary way, that is, the bar is introduced into
the groove at the front of the rolls and the rolled bar is delivered from the rolls
at the back thereof. By passing the partly formed flat bar between the diagonal
or inclined grooves of the last mentioned pair of rolls the figure of one of the
flat faces of the bar is squared or perfected. The flat bar thus rolled is then
passed between a nearly similar pair of finishing grooved rolls but the flat grooves
are inclined in the opposite direction and their angles are without flats."
By the action of these finishing rolls the other face of the bar is squared or
perfected and the edges of the bar also squared, that is, rolled at right angles
to the parallel sides or faces of the bar. A flat bar of iron or steel without burr
or fin and having its sides squared, that is, its adjacent sides perfectly at right
angles, is produced.
Figures 1, 2, 3 and 4 of the accompanying drawings represent in side elevation
and cross section the preliminary rolling stages of the flat bar of iron or steel
according to our invention and Figure 5 represents in side elevation and cross
section the squared or finished flat bar having its sides perfectly parallel and at
right angles to its edges.
Figure 6 represents the pair of collared rolls, partly in elevation and partly in
section, which we use for the preliminary rolling stages of the bar and Figures 7
and 8 represent in side elevation, partly in section, the finishing pairs of rolls
which we employ for perfecting the figure of the bar.
In conducting the rolling operation according to our invention and by the use
of the rolls represented we proceed as follows: After having reduced the heated
billet of iron or steel to a bar square in cross section and of a size suitable for the
production of a flat bar, we take the said square bar and pass it through the groove
or space 1 of the pair of collared rolls Figure 6 so as to produce the bar represented
in Figure 1, the said bar being slightly wedge shaped in cross section or having
inclined sides. We take the bar Figure 1 and pass it through the groove or
space 2 of the said rolls Figure 6 so as to flatten or slightly reduce the thickness
of the bar and give it the sectional form represented in Figure 2. We next pass
the partly rolled bar Figure 2 through the groove or space 3 of the rolls Figure 6
so as to further flatten or reduce the thickness of the bar and give it the sectional
form represented in Figure 3.
The partly rolled har Figure 3 is now passed in succession through the grooves
of the finishing pairs of rolls Figures 7 and 8. The said rolls are furnished with
flat grooves which are inclined or arranged diagonally, the upper and lower angles
of the flat groove 4 of the rolls Figure 7 being slightly flattened, the flat groove 5
of the other pair of finishing rolls Figure 8 being without flats at its angles. It
will be seen that the flat groove 4 of the rolls Figure 7 is inclined in a direction

page_text: opposite to that of the groove 5 of the rolls Figure 8. The partly formed flat
bar Figure 3 is first passed through the inclined groove 4 of the rolls Figure 7
whereby one of the inclined faces of the bar is squared or perfected, two of the
angles of the bar being flattened as represented in Figure 4. The nearly fashioned
flat bar Figure 4 is finally passed through the inclined groove 5 of the rolls
Figure 8 whereby the other inclined face of the bar is squared or perfected the
bar being further flattened on its adjacent opposite sides or edges and the said
edges at the same time squared. The bar after being thus finally rolled has
the sectional form represented in Figure 5 and is without burr or fin and its
adjacent sides are at right angles to one another, thereby producing a bar having
in cross section the figure of a practically perfect rectangle.
Although we have only represented a single inclined groove in each of the
finishing rolls Figures 7 and 8 yet rolls of the construction represented having
more than one inclined groove may be employed in the finishing stages of the
manufacture of the flat bar.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed, we declare that we claim
as our invention of "Improvements in rolling flat bars of iron or steel and in
rolls to be used for that purpose"
:
First Rolling flat bars of iron or steel having in cross section the figure of a
rectangle by subjecting a flat bar in succession to the several rolling operations
illustrated by Figures 1, 2, 3, 4 and 5 of the accompanying drawings.
Secondly-The improved grooved rolls hereinbefore described and illustrated
in Figures 6, 7 and 8 of the accompanying drawings to be used in the rolling
operations referred to in the first claim.
