IMPROVEMENTS IN MA- CHINERY FOR ROLLING BAR IRON, STEEL, AND OTHER METALS OR MALLEABLE MATTERS
Year: 1860

page_text: LETTERS PATENT to Mathieu Bonnor, of Eurville, Town in the French
Empire, Manufacturer, for the Invention of "IMPROVEMENTS IN MA-
CHINERY FOR ROLLING BAR IRON, STEEL, AND OTHER METALS OR MALLEABLE
MATTERS."
Sealed the 1st November 1860, and dated the 2nd May 1860.
PROVISIONAL SPECIFICATION left by the said Mathieu Bonnor at
the Office of the Commissioners of Patents, with his Petition, on the
2nd May 1860.
I, MATHIEU BONNER, of Eurville, Town in the French Empire, Manufac
turer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR ROLLING BAR IRON, STEEL, AND OTHER METALS OR
MALLEABLE MATTERS," to be as follows:-
Hitherto the rolling of iron and steel into bars has been effected by the use
of one pair of rollers, in which are cut grooves decreasing in size upon the length
of the rollers; in using such rollers the bar must be entirely clear of one
groove before the other end of the bar can be inserted into the next groove, and
much time is necessarily occupied in the passage of the bar successively through
the different size grooves in the rollers; now, the object and intention of this
Invention is to expedite the operation, which I propose to effect by employing
several pairs of rollers placed in parallel rows, so that the bar on leaving the
first pair of rollers is at once made to enter a second pair placed opposite to
and in front of the first pair, from thence the bar passes to a third pair of
rollers placed in the same position before the second, and so on till the bar is
finished. The rolling of the bar is thus carried on from one pair of rollers

page_text: to the other without interruption, thereby effecting a considerable saving
of time.
In the practical application of this process, in order to regulate the speed of
each succeeding pair of rollers regard must be had to the lengthening of the
bar in the various grooves, the rollers must increase successively in diameter if 5
they revolve on their axes at the same speed, or the speed must be gradually
increased if the diameters remain uniform.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Mathieu Bonnor, in the Great Seal Patent Office on the
1st November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MATHIEU
BONNOR, of Eurville, Town in the French Empire, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of May, in the year of our Lord One
thousand eight bhundred and sixty, in the twenty-third year of Her reign,
did, for Herself, ler heirs and successors, give and grant unto me, the
said Mathieu Bonnor, Her special license that I, the said Mathieu Bonnor,
my executors, administrators, and assigns, or such others as I, the said
Mathieu Bonnor, my executors, administrators, and assigns, should at any
time agreo 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 "IMPROVEMENTS IN
MACHINERY FOR ROLLING BAR IRON, STEEL, AND OTHER METALS OR MALLEABLE
MATTERS," upon the condition (amongst others) that I, the said Mathieu
Bonnor, my executors or administrators, by an instrument in writing under
iny 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
sane 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 Mathieu Bonnor, do hereby declaro
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statoment, that is to say:-

page_text: Hitherto the rolling of iron and steel into bars has been effected by the use
of one pair of rollers, in which are cut grooves decreasing in size upon the
length of the rollers; in using such rollers the bar must be entirely clear of
one groove before the other end of the bar can be inserted into the next groove,
and much time is necessarily occupied in the passage of the bar successively
through the different size grooves in the rollers. Now, the object and inten-
tion of this Invention is to expedite the operation, which I propose to effect
by employing several pairs of rollers placed in parallel rows, so that the bar on
leaving the first pair of rollers is at once made to enter a second pair placed
opposite to and in front of the first pair; from thence the bar passes to a third
pair of rollers placed in the same position before the second, and so on till tho
bar is finished. The rolling of the bar is thus carried on from one pair of
rollers to the other without interruption, thereby effecting a considerable saving
of time.
In the practical application of this process, in order to regulate the speed of
cach succeeding pair of rollers, regard must be had to the lengthening of the
bar in the various grooves, the rollers must increase successively in diameter,
if they revolve on their axis at the same speed, or the speed must be gra-
dually increased if the diameters remain uniform.
Having thus briefly referred to the nature of the said Invention, I will now
particularly describe the same, reference being had to the accompanying
Drawing, in which Figure 1 represents a section of a bar of iron or steel A,
drawn between several parallel and consecutive rollers B, B', B, the rollers in
this case being of equal diameter, but rotating with a progressive speed;
Figure 2 also shews a section of a bar of iron or steel A', under the action of
parallel rollers B, B', B, of different diameters, but driven, with the same
velocity; Figure 3 is an elevation of an arrangement of several parallel rollers
having equal diameters, and provided with wheels, pullies, and chains for
working them; Figure 4 is an end view of the same arrangement; on these
figures similar letters refer to corresponding parts. In this arrangement the
rollers are formed of the same diameter, but are driven with different velocities.
The rollers are shewn in a vertical position, but they may be placed horizon-
tally. The main shaft a is fitted with a bevel pinion b, which receives motion
from the bevel wheel c. On the shaft a are placed at suitable distances apart
the small bevel wheels d, d, which actuate the bevel wheels e on the hori-
zontal shafts f. At the opposite extremity of these shafts are fixed the toothed
wheels h, on which the Vaucanson's chaius i are passed. These chains are a
useful substitute for straps and pullies. Theso chains give motion to the
toothed wheels j, which are mounted on the shaft of the lower driving pinion K'.

page_text: Another series of bevel wheels 9 are mounted on the shaft a gearing with
the bevel wheels 2, fixed on the lower part of the vertical shaft m. At
the upper extremity of this shaft are keyed the toothed wheels n, on which
are passed the Vaucanson's chains o, for driving the small toothed wheels r,
fixed to the nxis of one of the grooved rollers p, p, these rollers work together
by the two pinions 9, 9. The pinion d and g, as well as the wheels e, h, j, n,
and r, have different diameters, so as to transmit to the horizontal rollers
K, K', and grooved vertical rollers p, p, a progressive speed, as desired, the
iron being thus rolled by passing from one pair of rollers to the other to the
last pair.
Having now fully described and set forth the nature and object of the said
Invention of "Improvements in Machinery for Rolling Bar Iron, Steel and
other Metals or Maleable Matters," together with the best means I am
acquainted with for carrying the same into practical effect, I would here
remark that I do not confine myself to the exact mode of carrying out the
Invention, as herein described, but reserve to myself the right of modifying
the same; and I hereby declare that what I claim and desire to be secured by
the herein-before in part recited Letters Patent is as follows; I claim,―
First, the arrangement of the rollers in several series parallel to each other
for rolling or drawing iron, steel, or other metals, as herein-before described,
and referred to in the annexed Drawings.
Secondly, the peculiar construction of the rollers and the mode of actuating
the same, as herein-before described and shewn in the accompanying
Drawing.
In witness whereof, I, the said Mathieu Bonnor, have hereunto set my
hand and seal, this Twenty-sixth day of October, in the year of our
Lord One thousand eight hundred and sixty.
