PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd February 1872.
I, WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand,
in the County of Middlesex, Patent Agent, do hereby declare the
nature of the said Invention for " CERTAIN IMPROVEMENTS IN ROLLING
MILLS OR MACHINES FOR MANUFACTURING BAR IRON," a communication to me
from abroad by Hyacinthe Vigour, of Charleville, Ardennes, France,
Iron Merchant, to be as follows:

mill, and by means of grooved cylinders, iron bars having throughout
their entire length, regularly and alternately, round and square parts of
equal diameter, because as there enters more iron into a square than into
a round the round parts are necessarily of a greater diameter than the
side of the square or present large seams or burrs ("bavures.")
The object of this Invention is to remedy this defect,-
Firstly. By placing immediately behind two horizontal cylinders,
grooved partly round and partly square, two vertical cylinders having
exactly similar grooves.
Secondly. By placing between the horizontal cylinders and the vertical
cylinders a continuous guide, which bevelled penetrates nearly to the
centre of the cylinders, and conducts the iron issuing from the horizontal
cylinders into the vertical cylinders.
The frame of the horizontal cylinders and those of the vertical cylinders
are independent although resting on one main framing, which it is
considered needless to show on the accompanying Sheet of Drawing, as
it resembles all rolling mill frames, and may be of any form.
In the manufacture the iron as it leaves the first pair of cylinders is
perfectly made in its square part, but has on its round parts seams or
burrs which are immediately flattened by the vertical cylinders.
The vertical cylinders are excellent correctors, inasmuch as they
immediately, and always inversely, take the iron issuing from the
horizontal cylinders.
This double instantaneous operation gives a perfect product :-In fact
the iron being unable in the rolling to escape and cease to take the
identical shape of the grooves, except at the junction of the cylinders,
it can as it issues from the horizontal cylinders be defective only in one
direction, and when leaving the vertical cylinders it can only be defective
in the contrary direction; the iron has therefore no escape and is obliged
to take the identical shape of the grooves.
Round and square bar iron is only mentioned as an example, inas-
much as this Invention is applicable to the rolling of other iron of
different profiles or sections on a same bar, and may even be used with
advantage in the manufacture of bars of a single section.
I will now describe the working of the apparatus, reference being had

page_text: to the accompanying Sheet of Drawing, upon which Figure 1 is an
elevation of an apparatus embodying this Invention seen from. the side
of the horizontal cylinders and drawn to a scale of th; Figure 2 is an
elevation of the same seen from the side of the vertical cylinders and

Explanation of the actuating mechanism :-The extension C of the
cylinder A coupled to the motor by means of a clutch gives motion to
the said cylinder. By means of the toothed wheels D and D', fixed
on the axles of the cylinders A and A¹, the cylinder A actuates the
cylinder A¹. On the extended axle of the cylinder A' is a toothed
wheel E, which combined with the toothed wheel E¹ transmits motion to
the shaft F. The shaft F by the aid of the bevel pinion G acts on the
bevel pinion G¹ set on the extended axle of the cylinder B by means of
the toothed gearing H and H¹.
Any lagging of the vertical cylinders by reason of the wear of the teeth
of the gearing will be corrected either by means of conical wedges, or by
employing a loose toothed wheel united by a screw to a fixed clutch or
coupling either on the axle of the cylinders or of the shaft F, or by any
means which may be found convenient.
The frame of the vertical cylinders may be moveable and slide in one
direction or the other together with all its toothed gearing, so that the
position of the grooves of the vertical cylinders may be regulated in
relation to those of the horizontal cylinders.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent
Office on the 20th August 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of No. 11, Wellington Street, Strand, in the County of
Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of February, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Gedge, Her special
licence that I, the said William Edward Gedge, my executors,
administrators, and assigns, or such others as I, the said William
Edward Gedge, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "CERTAIN IMPROVEMENTS IN ROLLING MILLS OR MACHINES FOR
MANUFACTURING BAR IRON," a communication to me from abroad by
Hyacinthe Vigour, of Charleville, Ardennes, France, Iron Merchant,
upon the condition (amongst others) that I, the said William Edward
Gedge, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Edward Gedge, 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:
Hitherto it has been found impossible to manufacture at the rolling
mills, and by means of grooved cylinders, iron bars having throughout
their entire length, regularly and alternately, round and square parts of

page_text: equal diameter, because as there enters more iron into a square then inte
a round the round parts are necessarily of a greater diameter than the
side of the square, or present large seams or burrs ("bavures").
a round the round parts are necessarily of a greater diameter than the
side of the square, or present large seams or burrs ("bavures").
The object of this Invention is to remedy this defect,—
Firstly. By placing immediately behind two horizontal cylinders,
grooved partly round and partly square, two vertical cylinders having
exactly similar grooves.
Secondly. By placing between the horizontal cylinders and the vertical
cylinders a continuous guide, which bevelled penetrates nearly to the
centre of the cylinders, and conducts the iron issuing from the horizontal
cylinders into the vertical cylinders.
I will now describe the working of the apparatus, reference being had
to the accompanying Sheet of Drawing, upon which Figure 1 is an
elevation of an apparatus embodying this Invention seen from the side
of the horizontal cylinders; Figure 2 is an elevation of the same seen
from the side of the vertical cylinders; Figure 3 is a bird's-eye view of
same, showing the guide for the bar. Figures 1, 2, and 3 are drawn to
a scale of 1/10th.
Figure 4 is a section of horizontal cylinders and their grooving, drawn
to a scale of th.
Figure 5 is an elevation of the guide, and Figure 5* a section at o, p,
Fig. 6, drawn to a scale of th; Figure 6 is a plan of same; Figure 7
is a section of same at k, n, Fig. 5.
Figure 8 is an elevation showing shape of grooves of vertical cylinders;
and Figure 9 is a bar of alternately round and square section.
A, A¹, indicate the horizontal cylinders; B, B', the vertical cylinders;
I, the continuous guide, taking the iron as it leaves the horizontal
cylinders to guide it into the vertical cylinders.
Explanation of the actuating mechanism:-The extension C of the
cylinder A, coupled to the motor by means of a clutch, gives motion to the
said cylinder. By means of the toothed wheels D and D', fixed on the
axles of the cylinders A. and A', the cylinder A actuates the cylinder A'.
On the extended axle of the cylinder A¹ is a toothed wheel E,.which
combined with the toothed wheel E¹ transmits motion to the shaft F.
The shaft F by the aid of the bevel pinion G acts on the bevel pinion G¹

page_text: set on the extended axle of the cylinder B by means of the toothed
gearing H and H¹.
Any lagging of the vertical cylinders by reason of the wear of the
teeth of the gearing will be corrected either by means of conical
wedges or by employing a loose toothed wheel united by a screw to a
fixed clutch or coupling either on the axle of the cylinders or of the
shaft F, or by any means which may be found convenient. The frame
of the vertical cylinders may be movable and slide in one direction or
the other, together with all its toothed gearing, so that the position of
the grooves of the vertical cylinders may be regulated in relation to
those of the horizontal cylinders.
The frame of the horizontal cylinders and those of the vertical
cylinders are independent although resting on one main framing, which
it is considered needless to show on the accompanying Sheet of Drawing,
as it resembles all rolling mill frames, and may be of any form.
In the manufacture the iron as it leaves the first pair of cylinders is
perfectly made in its square part, but has on its round parts seams or
burrs, fins or inequalities, which are immediately flattened by the vertical
cylinders.
1
The vertical cylinders are excellent correctors, inasmuch as they 2
immediately and always inversely take the iron issuing from the
horizontal cylinders. This double instantaneous operation gives a perfect
product. In fact the iron being unable in the rolling to escape, and
cease to take the identical shape of the grooves except at the junction
of the cylinders, it can as it issues from the horizontal cylinders be 2
defective only in one direction, and when leaving the vertical cylinders
it can only only be defective in the contrary direction; the iron has there-
fore no escape, and is obliged to take the identical shape of the grooves.
Round and square bar iron is only mentioned as an example, inasmuch
as this Invention is applicable to the rolling of other iron of different 3
profiles or sections on a same bar, and may even be used with advantage
in the manufacture of bars of a single section.
Having now described and ascertained the nature of the said
Invention communicated to me as aforesaid, and in what manner the
same is or may be performed, I would have it understood that I do not 3
confine myself to the precise details herein given, as such may be varied

page_text: while retaining the essential features of the Invention, and that what I
claim as secured to me by the herein-before in part recited Letters
Patent is,―
Firstly. The combination of the horizontal cylinders A, A', with the
vertical cylinders B, B', substantially as and for the purposes herein-
before set forth.
Secondly. The combination with the cylinders A, A¹, and B, B¹, of
the guide I, substantially as and for the purposes herein-before set forth.
In witness whereof, I, the said William Edward Gedge, have
hereunto set my hand and seal, this Nineteenth day of August,
in the year of our Lord One thousand eight hundred and
seventy-two.
