IMPROVEMENTS IN MEANS OR APPARATUS FOR ROLLING METALS
Year: 1861

page_text: LETTERS PATENT to Guillaume Prodon-Bonneton and Marthe Guillaume
Prodon, both of Thiers, in the Department of Puy-de-Dome, in the
Empire of France, Engineers, for the Invention of "IMPROVEMENTS IN
MEANS OR APPARATUS FOR ROLLING METALS."
Sealed the 13th May 1862, and dated the 18th November 1861.
PROVISIONAL SPECIFICATION left by the said Guillaume Prodon-
Bonneton and Marthe Guillaume Prodon at the Office of the Commis-
sioners of Patents, with their Petition, on the 18th November 1861.
We, GUILLAUME PRODON-BONNETON and MARTHE GUILLAUME PRODON, both
of Thiers, in the Department of Puy-de-Dome, in the Empire of France;
Engineers, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR ROLLING METALS," to be as follows:-
The Invention relates to a combination of means by which facility is
obtained for the production of various forms in relief. For this purpose, we
form the extended figures or forms on the surface of rings which are applied
to an axle so as to be held thereon by screw nuts, aided by grooves and keys,
or ribs. For change of pattern or figure, it will only be necessary to remove
one pair of rings, or one of each, and replace them by others. The metal to
have form, or figure given to it is conducted. correctly to its position on the

page_text: surface of the rollers by guides which are capable of adjustment. The bear-
ings of the upper rolls are supported or operated by screws geared so as to be
operated together, and thereby to insure uniformity of pressure, with capability
of variation of pressure if desired during the progress of the work. These
means are particularly applicable to various articles of cutlery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said. Guillaume Prodon-Bonneton and Marthe Guillaume Prodon
in the Great Seal Patent Office on the 16th May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GUIL-
LAUME PRODON-BONNETON and MARTHE GUILLAUME PRODON, both of Thiers, in
the Department of Puy-de-Dome, in the Empire of France, Engineers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Guillaume Prodon-Bonneton and Marthe Guillaume Prodon, Her special
licence that we, the said Guillaume Prodon-Bonneton and Marthe Guillaume
Prodon, our executors, administrators, and assigns, or such others as we, the
said Guillaume Prodon-Bonneton and Marthe Guillaume Prodon, our execu-
tors, 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 "IMPROVEMENTS IN MEANS OR APPARATUS FOR
ROLLING METALS," upon the condition (amongst others) that we, the said Guil-
laume Prodon-Bonneton and Marthe Guillaume Prodon, our executors or
administrators, by an instrument in writing under our or their hands and
seals, or under the hand and seal of one of us or them, 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 Guillaume Prodon-Bonneton, on
behalf of myself and the said Marthe Guillaume Prodon, do hereby declare

page_text: 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.thereof; that is to say:-
to remove
The Invention relates to a combination of means by which facility is
obtained for the production of various forms in relief. For this purpose, we
form the extended figures or forms ou the surface of rings which are applied
to an axle so as to be held thereon by screw nuts, aided by grooves and keys,
or ribs. For change of pattern or figure, it will only be necessary
one pair of rings, or one of each, and replace them by others. The metal to
have form or figure, given to it is conducted correctly to its position on the
surface of the rollers by guides which are capable of adjustment. The bear-
ings of the upper rolls are supported or operated by screws geared so as to be
operated together, and thereby to insure uniformity of pressure, with capability
of variation of pressure if desired during the progress of the work. These
means are particularly applicable to various articles of cutlery.
But that the nature of the Invention may be better understood we will,
by the aid of the accompanying Drawings, proceed to describe means which
we employ in carrying the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a front view; Figure 2 an end view; Figure 3 a plan;
Figure 4 a vertical section; and Figure 5 a transverse section of apparatus
constructed according to our improvemements. In each of these Figures the
same letters indicate corresponding parts wherever they occur.
a, a, is the
main framing; b, c, are a pair of axles, to which motion is given by suitable
gear. The axle 6 is supported in bearings 1, and the axle c is formed with a
centre flange c¹, and is adapted to receive rings d, d, which are pressed tightly
against the flange c¹, by means of set screws e, e, whilst the rings d, d, are held
from turning on the shaft c, by means of keys, acting in grooves or by ribs.
Upon these rings d, d, the pattern or figure desired to be produced by rolling
action is obtained, and such pattern or figure is imparted by passing the metal
to be operated upon between the surface of either of the rings d, d, and the
surface of the roller b. For change of pattern or figure it will only be neces-
sary to remove one pair of rings or one of each, and replace them by others.
ff, are guides capable of adjustment by means of the screws f, f, for.
conducting the metal to be operated upon correctly to between the respective
rings d, d, and the surface of the roller b. The bearings c² of the upper
rolls are acted upon by screws g, g, the threads of which are respectively right

page_text: and left handed, so that when motion is given to one of them by the winch
handle h, corresponding 'motion may be simultaneously given to the other by
the toothed wheels i, i, to insure uniformity of pressure, with capability of
variation of it if desired during the progress of the work.These-means-are
particularly applicable to giving form to knives, sword blades, bayonets, and
other articles-of-cutlery.
Having thus described the nature of the said Invention, and the means
which we have found to answer in carrying the same into effect, we would
have it understood that we do not confine ourselves to the precise details
shewn and described, nor do we claim the various parts separately considered;
but what we do claim is the adaptation or combination of means or apparatus
for rolling metals, substantially as explained.
.
In witness whereof, I, the said Guillaume Prodon-Bonneton, have here-
unto set my hand and seal, this Tenth day of May, in the year of our
Lord One thousand eight hundred and sixty-two.
