IMPROVEMENTS IN THE MACHINERY OR APPARATUS FOR ROLLING IRON
Year: 1860

page_text: LETTERS PATENT to Eugene Franquinet, of Augrée, in the Kingdom of
Belgium, and of 4, South Street, Finsbury, London, Manufacturer,
for the Invention of "IMPROVEMENTS IN THE MACHINERY OR APPARATUS
FOR ROLLING IRON."
Sealed the 2nd January 1861, and dated the 11th July 1860.
PROVISIONAL SPECIFICATION left by the said Eugene Franquinet at
the Office of the Commissioners of Patents, with his Petition, on the
11th July 1860.
I, EUGENE FRANQUINET, of Augrée, in the Kingdom of Belgium, and of
4, South Street, Finsbury, London, Manufacturer, do hereby declare the
nature of the said Invention of "IMPROVEMENTS IN THE MACHINERY OR APPARATUS
FOR ROLLING IRON," to be as follows, that is to say:
The mode hitherto adopted for the manufacture of flat and square bar iron
of commerce requires a number of rollers or cylinders almost equal to that of
the different sizes or widths of the iron to be obtained, but by the improved
machinery or apparatus one pair of rollers is sufficient for the manufacture of
several sizes of flat or square iron without interrupting the action of the
machine or changing the rollers.
The machine or apparatus is composed of two suitable standards, between
which are placed the rollers or cylinders formed with grooves of variable

page_text: width according to the size of the square or flat bar iron required to be made.
The axis of the upper roller works in suitable slide blocks, and may be raised
by weighted levers, springs, or other suitable mechanism. The upper roller

by the said Eugene Franquinet in the Great Seal Patent Office on
the 9th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, EUGENE
FRANQUINET, of Augrée, in the Kingdom of Belgium, and of No. 4, South
Street, Finsbury, London, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of July, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Eugene Franquinet, Her special licence that I, the said Eugene Franquinet,
my executors, administrators, and assigns, or such others as I, the said Eugene
Franquinet, 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 of "IMPROVE-
MENTS IN THE MACHINERY OR APPARATUS POR ROLLING IRON," upon the condition
(amongst others) that I, the said Eugene Franquinet, my executors or admi-
nistrators, 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 Eugene Franquinet, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereto annexed, and to
the letters and figures marked thereon, that is to say :-
The mode hitherto adopted for the manufacture of flat and square bar iron
of commerce requires a number of rollers or cylinders almost equal to that of
the different sizes or widths of the iron to be obtained, but by the improved

page_text: machinery or apparatus one pair of rollers is sufficient for the manufacture of
several sizes of flat or square iron, without interrupting the action of the
machine or changing the rollers.
The machine or apparatus is composed of two suitable standards, between
which are placed the rollers or cylinders, formed with grooves of variable
width, according to the size of the square or flat bar iron required to be made.
The axis of the upper roller works in suitable slide blocks, and may be raised
by weighted levers, springs, or other suitable mechanisın. The upper roller
is kept in its proper position by screws actuated by suitable gearing.
I will now proceed to describe more particularly the nature of my said
Invention, and the manner of performing the same, reference being made to
the annexed Drawing, in which Figure 1 represents a plan of the apparatus
for rolling iron, Figure 2 a front elevation, and Figure 3 an end elevation of
the same. A, A', are two standards, supported on a suitable base B. Each
standard is formed with a large slot or opening C. D, D', are two rollers
formed with rings and grooves, the grooves of the upper roller D being made
to correspond with the projecting rings of the lower roller D'. The axis E
of the upper roller works in the slide blocks or bearings F, F. The upper
cylinder or roller may be raised or lowered by means of the set screws G, G¹,
and weighted levers H, H. Each screw is formed with a toothed pinion I,
gearing with the spur wheel J, put in motion by the hand wheel K. The
lower slide blocks or bearings F, on which the axis of the upper roller rests,
are supported by the vertical rods L, L', attached to the short ends of the
pressure levers H, H', by the cross rods M, M'. These levers work on fulcra,
supported by the links N, N¹. The long end of each lever is provided with
a weight O, for giving the requisite pressure. Instead of these weighted
levers, springs may be employed for the same purpose. P, scale or indicator.
The peculiar construction of these rollers presents a great advantage over
those at present adopted. By the projecting rings of one roller entering the
corresponding grooves of the other roller, square or flat bars of iron may be
formed of any desired width and thickness more economically than by the
present mode, and without requiring more than one pair of rollers.
Having now described the nature of my said Invention, and the manner
of performing the same, I wish it to be understood that I do not confine
myself to the exact mode of constructing the apparatus as herein described, as
many modifications may be made without departing from the main feature of
my Invention; but what I claim as new, and wish to be protected by the
herein in part recited Letters Patent, is,―
First, the peculiar construction and employment of one pair of rollers D, D',

page_text: for rolling square or flat bar iron of various sizes, as herein-before described,
and shewn in the annexed Drawing.
Secondly, the combination and employment of the levers H, H', and screws
G, G', for raising or lowering the rollers, as herein-before described, and
shewn in the annexed Drawing.
In witness whereof, I, the said Eugene Franquinet, have hereto set my
hand and seal, this Fifth day of January, in the year of our Lord
One thousand eight hundred and sixty-one.
E. FRANQUINET. (L.S.)
