PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition, on
the 3rd October 1865.
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, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANU-
PACTURE OF SHEET IRON OR STEEL CYLINDERS FOR BOILERS AND SIMILAR ARTICLES,
AND IN THE APPARATUS RELATING THERETO," communicated to me by Benoit,
Bouniard, Engineer, a person residing at Terre Noire, in the Empire of France,
aforesaid, to be as follows:-
This Invention relates to an improved mode of and apparatus for manu-
facturing cylinders of sheet steel or iron in the rolls without riveting or

page_text: soldering, chiefly adapted for steam or other boilers, and similar articles. It
consists, firstly, in obtaining cylindrical pieces of iron or steel without solder-
ing, joint, or rivet; and, secondly, in the improved arrangement and construc-
tion of the rolls necessary for producing this result. A cylinder of suitable
thickness is produced by running into a mould with a coré any fusible and
malleable material, but preferably steel obtained by Bessemer's process. The
upper roll is then introduced into this cylinder by means of a moveable cage,
worked by a steam cylinder or otherwise, so as to allow the roller to enter the
casting. This upper roll being fixed and the lower one larger and moveable,
the pressure is operated from below in any suitable way. In order to join
several of these cylinders the rolls are made with grooves, so as to form an
interior flange on the female or outside cylinder, and an outside flange on the
male cylinder. To join them the female cylinder is heated, and the male
made to enter it in a cold state. The contraction of the heated end renders it
impossible to separate the two without breaking.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henri Adrien Bonneville in the Great Seal Patent Office
on the 29th March 1866.
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 Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of October, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henri Adrien Bonneville, Her special licence, that I, the said Henri
Adrien Bonneville, my executors, administrators, and assigns, or such others
as I, the said Henri Adrien Bonneville, my executors, administrators, and
assigns, should in 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 THE MANUFACTURE OF SHEET IRON OR STEEL CYLINDERS FOR
BOILERS AND SIMILAR ARTICLES, AND IN THE APPARATUS RELATING THERETO," a com-
Dunication from Benoit Bouniard, Engineer, a person residing at Terre Noire;

page_text: in the Empire of France, aforesaid, upon the condition (amongst others)
that I, the said Henri Adrien Bonneville, my executors or administrators,
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 Inven-
tion, 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 Henri Adrien Bonneville, do hereby
declare 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 :-
This Invention relates to an improved mode of and apparatus for manu-
facturing cylinders of sheet iron or steel in the rolls without rivetting
or soldering, chiefly adapted for steam or other boilers, and similar articles.
It consists, firstly, in obtaining cylindrical pieces of iron or steel without
soldering, joint, or rivet; and, secondly, in the improved arrangement and
construction of the rolls necessary for producing this result. A cylinder
of suitable thickness is, produced by running into a mould with a core any
fusible and malleable material, but preferably steel obtained by the process
known as "Bessemer's." The upper roll is then introduced into this cylinder
by meatis of a moveable cage, worked by a steam cylinder or otherwise, so as
to allow the roller to enter the casting. This upper roll being fixed, and the
lower one larger and moveable, the pressure is operated from below in any
suitable way. In order to join several of these cylinders the rolls are made
with grooves, so as to form an interior flange on the female or outside
cylinder, and an outside flange on the male cylinder. To join them the female
cylinder is heated, and the male made to enter it in a cold state. The
contraction of the heated end renders it impossible to separate the two without
breaking..
To make the said Invention more clearly understood, I will now proceed
to describe the construction and operation of the same, referring to the
accompanying Drawings, in which Fig. 1 represents an elevation of the
rolling apparatus, and Fig. 2 & 3 the improved joints, with and without
bolts.
In Fig. 1 the apparatus is shown as it appears when the cylinder is about
to be slid on the upper roller A in the line of the arrow R. The moveable
cage C is withdrawn by a stroke of the piston of the steam cylinder D. This
cage slides on the platform E during its come-and-go movements. When
this cage is removed the upper roll still remains fixed at its place, being

page_text: supported by the other two cages F and G. The lower roll B is lowered
in order to facilitate the introduction of the sheet iron cylinder to be rolled.
It is raised or lowered at will by an apparatus placed beneath in the pit,
constructed as follows:-This apparatus is moved at the required moment
by a toothed wheel H, fixed on the shaft I, and worked at H¹ by the rotation
of the pinion K, the toothed wheels L, L', turning and communicating to
each of the screws M (right and left) the ascending and descending move-
ments, according to the direction of the driving power, which is determined
by the movements of an attacking lever so that at a given moment the lower
moveable roll. B may be either raised for working or lowered to admit the
sheet-iron cylinder. The screws M are lodged in blocks N which may be
moved vertically by means of levers. By pressing on one or both of the
levers P, P¹, a vertical pressure is exercised on the moveable cylinder B.
The sheet-iron ring or cylinder is maintained during its rotatory movement
by guide rolls T placed at each side. A suitable position is given to these
guide rolls according to the width of the sheet-iron cylinder by means of the
wheel U, whose shaft U¹ is provided with an endless screw turning the
wheels V and X, the latter moving the roll bearer Y, turning over by means
of a rack Z placed at the top of the roll bearer, whose pivot is at Z. At
each end of the roll is placed one of these roll bearers. If the sheet-iron
cylinder is of very large diameter other guide rolls may be adapted in order
to support it while turning.
Having thus described the nature of the said Invention, and in what
manuer the same is to be carried into effect, what I claim is,―
Firstly, the manufacture of cylinders of sheet iron or steel without joints or
rivets...
Secondly, the improved arrangement of rolling apparatus above described,
embodying, 1st, an upper cylinder turning loosely on its bearings; 2d, a
moveable lower roll; and, 3d, the means of sliding the sheet-iron cylinder on
the upper roll by means of a cage moved by a steam cylinder or otherwise.
In witness whereof I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Twenty-sixth day of March, in the year of
our Lord One thousand eight hundred and sixty-six.
