page_text: PROVISIONAL SPECIFICATION left by William Edward Gedge at the
Office of the Commissioners of Patents, with his Petition, on the
27th May 1870.-A communication from abroad by Pierre Michel
Sibut, senior, of Amiens (Somme), France, Manufacturer.
I, WILLIAM Edward Gedge, of the Firm of John Gedge and Son,
of No. 11, Wellington Street, Strand, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention
for "A NEW OR IMPROVED SYSTEM OF GROOVES FOR ROLLING AND SHAPING IRON
OR OTHER METALS," a communication to me from abroad by Pierre Michel
Sibut, senior, of Amiens, (Somme,) France, Manufacturer, to be as.
follows:
This Invention relates to a particular system of grooves for producing
all patterns of iron or other metals of any polygonal section rolled and
modified or moulded at once both on flat and edge, or on several or all
faces, and several or all edges as well in breadth as in thickness and in
length.

page_text: The grooves which form the subject of this Invention are like all
laminating grooves arranged on a pair of rolls of any diameter, made
of cast iron or other metal, and working with a rotary motion in the
same manner as every pair of laminating rolls, either horizontally in a
frame or cage similar to those common to all rolling mills, and driven
by the same mechanical means, or horizontally or vertically with con-
tinuous or alternating rotary motion, or with come-and-go motion
worked by any driving gear and motive power. Each pair of cylinders
may receive as many grooves as its length will permit. These grooves
like those of all laminating grooves are composed of two parts, the one
in projection on one of the two rolls and the other sunk in the second.
They differ therefrom inasmuch that in the ordinary grooves the male
or projecting part has two parallel lateral faces, which enter more or
less deeply but perpendicularly into the female or recessed part, exactly
embracing its equally parallel sides, so that these parallel plane surfaces
turn in contact with each other by a segment of each of their faces or
flat surfaces, whereas in the grooves forming the subject of this Invention
the edges being of a conical section or of a section derived from the
conical neither the one or the other part present plane surfaces in
contact, but only curved surfaces from whence it results that the pro-
jecting part being wedged or otherwise tightened on the hollow or
recessed part is in adhesion therewith only by points of their cir.
cumference. The general shape of these grooves is conical without lateral
parallel bases.
However in caso it should be considered necessary to
keep the special conical grooves more forcibly the one in the other and
prevent any shaking of the rolls a certain number of ordinary grooves
may be formed on them, such grooves however not to be used for rolling,
this operation being entirely confined to the special grooves, but simply
to keep the rolls strictly in proper juxtaposition.
Figure 1 of the accompanying Sheet of Drawing represents right
angled conical grooves of this Invention. They may according to
requirement be acute or obtuse angled. Further the conical section
of the special grooves may, according to the pattern to be obtained
assume forms having broken lines, or any round, ovoid, or curvilineal
lines, such for example as in Figures 2 to 10, which are however only
given as illustrations, and not to the exclusion of any other sections of
the same character, that is to say, based upon the principle of the
projecting grooves adhering to the hollow or sunken grooves only by

page_text: points of their circumference and not by plane surfaces. This system
of grooves is suitable for producing at a single pass any piece of iron,
copper, or other metal, with all variations of thickness on flat or edge,
or on several or all faces, as well as on several or all edges, whatever may
be the sections of the piece to be produced, whether parallellogramic,
square, trapezoidal, triangular, or polygonal, with entering or projecting
angles, or with round or curved lines, as for example all blooms differenced
in thickness in every direction to serve for the manufacture by hand
or machinery of shoes for horses, mules, or other animals, and every
section of bar, rod, or moulding of iron, copper, or other metal, with any
pattern in relief or hollow on one or several faces as on one or several
edges. Figures 11 to 15 are examples of blooms and of bars or rods with
mouldings or designs which may be obtained by this system of grooves
without excluding other forms. Whatever may be the form to be given
to the grooves according to the piece to be obtained, the design in view
is arranged (inverse to the effect to be produced, that is to say, in relief
for sunken impression, and sunk for impression in relief) whether it has
been cast with the grooves and rolls themselves by means of preliminary
moulds or patterns, whether cut at the lathe with graver and file in the pro-
jecting groove, or on its re-entering counterpart, or even in both together,
with similar or different designs or patterns on each in the manner
shewn, for example, Figures 1 to 10. The grooves may be fixed and
formed on the rolls themselves, or they may be made in one or several
moveable parts brought together and bolted upon axles, so that if this
method is preferred they may be replaced at will on these axles without
it being necessary to dismount and change the axles themselves. The
rolls having their special grooves fixed or moveable, prepared and shaped
as above stated according to the piece to be produced are placed in
their frame or cage with the special grooves tightened by wedges, the
one in the other, and the required rotary motion being given to them,
a bloom or bar of iron or other metal, heated or not heated according
to the ordinary method of rolling each kind of metal, and already brought
to a suitable preparatory section by ordinary roughing grooves of the
requisite form, being set in the space produced in the grooves by the
pattern to which they are cut and drawn by the rotary action of the
rolls, either forward or backward, takes in passing along the opening
formed by the pattern cut in the grooves all the forms of this pattern
either in projection or in bas-relief as well on its upper faces and
edges as on the lower and lateral ones.

page_text: It is thus for example that by modeling in the grooves designs, corre-
sponding inversely by relief or bas-relief with those Figures 11 to 15 of
the Drawing, pieces will be obtained similar to those indicated by the
same Figures 11 to 15, either in blooms or lengths passed separately the
one after the other through the grooves or in bars or rods rolled at a
single pass in their entire length. The blooms may also be passed
through two operations, the one making a first half of the bloom set
in the grooves by its middle or part of its developement and the other
the second half by operating in the same manner on this second half
of the bloom, these two successive operations being effected either by
one and the same pair of grooves or by means of two different pair with
a similar or a different pattern for the two parts of the bloom to be
successively rolled.
It will be evident that the various Figures on the annexed Sheet of
Drawing are simply given as examples of the results which may be
obtained by this Invention, and that the various sections and patterns
which may be produced by this system of grooves cannot be defined.
