Patent Agent, for the Invention of "IMPROVEMENTS IN THE MANUFAC-
TURE OF IRON RODS AND BARS OF DIFFERENT FORMS, AND IN THE APPARATUS
RELATING THERETO."-A communication from Adolphe Paul Englebienne,
Philippe Gobert, and Constant Pourbaix, Manufacturers, all residing at
Houding Aimeries in the Kingdom of Belgium.
COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville at
the Office of the Commissioners of Patents, with his Petition and Decla-
ration, on the 31st. March 1865, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices; 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF IRON RODS AND BARS OF DIFFERENT FORMS, AND IN THE
APPARATUS RELATING THERETO," communicated to me by Adolphe Paul Engle-
bienne, Philippe Gobert, and Constant Pourbaix, Manufacturers, all resident
at Houding, Aimeries, in the Kingdom of Belgium, and have petitioned Her

page_text: Majesty to grant unto me, my executors, administrators, and assigns, Her
Royal Letters Patent for the same, and have made solemn Declaration that it
is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification under my hand and seal
fully describes and ascertains the nature of the Invention, and the manner in
which the same is to be performed, reference being had to the accompanying
Drawing, that is to say:-
The object of this Invention is to simplify and considerably reduce the
different operations by which bars or rods of iron are obtained at the present
time.
The apparatus employed consists of a series of cylinders or rollers, in and
around each of which are cut grooves or flutes, having one or other, or half of
one or other, of the forms generally given to iron rods, viz., round, half
round, square, octagonal, and hexagonal, and this apparatus allows of using
iron slit by any of the known systems. The iron for any of the above forms
should undergo two operations; the lump on leaving the reheating furnace
should be worked in such a way as to be able to pass the slitter. As soon as
this operation has taken place; the first part of the work is done. As any kind
of slitting or cleaving apparatus may be used in connection with these improve-
ments it is unnecessary to enter into any details with regard to this part, the
Invention cousisting, as above stated, in the idea and the possibility of
transforming iron passed through the slitter in bars or rods of the different
forms.
The accompanying Drawing represents only the system or series of rolling
cylinders between which the bars of iron are passed after being slit in order to
arrive at the desired forms. The cylinders at the right hand of the pinions
(trundles) being identically similar to those placed on the left hand, in order to
obtain a double effect, are not shown in the Drawing. This series of cylinders
should be placed parallel to the cleaving apparatus, and all the rollers should
be of chilled iron. The iron rods on leaving the slitters are placed opposite
the pinions A.
In order to obtain square bars, the series of rollers represented in the
Drawing carries in the first cage B to the left of the pinions the chilled
cylinders C, C, provided with an ovalised groove or flute, which by the juxta-
position of the two cylinders forms a sort of drawing plate called a square
oval D, and another flute or groove, the juxtaposition of which with the
corresponding cylinder forms a perfect square E. The iron rods brought while
still in a heated state toward the pinions are taken by the roller and passed

page_text: first in the square oval D, then in the square E, and thus the square form is
obtained.
To obtain round rods, the series carries in the second cage F to the left of
the pinions A the chilled cylinders G, G, carrying half oval grooves, and in the
third cage, H, cylinders also chilled, I, I, having half round grooves. These
grooves by the juxtaposition of the two cylinders form an oval J, or a perfect
round M. The iron rods are passed first in the oval opening J, next in the
round one M, in order to obtain the round form desired.
To obtain half round bars or rods, the upper cylinder I of the cage
His replaced by a plain chilled cylinder, consequently the lower cylinder
only retains a half round groove in which the cut bar or rod is passed.
Lastly, to obtain hexagonal or octagonal bars or rods it is necessary to
replace, firstly, the chilled cylinders G, G, of the cage F by cylinders carrying
grooves, the juxtaposition of which forms either ovalised hexagons or ovalised
octagons, secondly, and the cylinders I, I, of the cage H, by cylinders carrying
grooves the union of which by the juxtaposition of the two cylinders forms a
perfect octagon or a perfect hexagon. The dimensions of the slit bars or rods
and of the grooves may vary according to the size required.
Having thus described the nature of the said Invention communicated
to me, what I claim and wish to secure by Letters Patent is,
Firstly, the combined use of slitting or cleaving apparatus and of grooved
rollers for making bars or rods of different forms, such as round, square, half
round, octagonal, hexagonal, and others.
Secondly, making rods or bars of the above forms or shapes in only two
passages between the rollers by the means above described and represented in
the accompanying Drawing.
Thirdly, the use of iron blanks slit from the lump for making rods or bars
of the above forms, and obtaining economy of time and labor and better quality
by rolling these bars or rods while in a heated state.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Thirty-first day of March, in the year of
our Lord One thousand eight hundred and sixty-five.
