in the County of Middlesex, Gentleman, for the Invention of "IMPROVE-
MENTS IN ROLLING METALS AND IN THE MACHINERY OR APPARATUS EMPLOYED
THEREIN." A communication from abroad by Hippolyte Ulysse Petin
and Jean Marie Gaudet, of the Firm of Petin, Gaudet, and Company,
of Rive de Gier in the Empire of France Ironmestors
Sealed the 24th April 1867, and dated the 6th November 1866.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson at
the Office of the Commissioners of Patents, with his Petition; on the
6th November 1866.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN ROLLING METALS AND IN THE MACHINERY OR APPARATUS
EMPLOYED THEREIN," a communication to me from abroad by Hippolyte Ulysse
Petin and Jean Marie Gaudet, of the Firm of Petin, Gaudet, and Company,
of Rive de Gier, in the Empire of France, Ironmasters, to be as follows:-
This Invention relates to a mode of rolling T, double T, or U shaped métal
bars and bar of a similar character, as well as bars of a flat or rectangular
section, and to the means employed therein, and consists essentially in the
employment of a pair of lateral adjustable rolls running loose' on vertical axes

page_text: in combination with a pair of rolls on horizontal axes, whereby the top,
bottom, and side or sides of the bar may be rolled simultaneously. The upper
roll may be raised or lowered by screw spindles or otherwise to give any desired
thickness of metal to the rolled bar and the two lateral rolls, which revolve
loosely on their axes, and which rotate by their contact with the metal passing
between; the horizontal rolls may also be adjusted nearer to or further from
the end of the horizontal rolls by screw spindles worked in concert or sepa-
rately, or otherwise adjusted. These several rolls will of course be shaped in
accordance with the form of bar to be produced, and any convenient arrange-
ment may be employed for giving motion to the main rolls or, if desired, to
the lateral rolls.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Johnson in the Great Seal Patent Office on the
4th May. 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47; Lincoln's Inn Fields, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of November, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Henry Johnson, Her special license that I, the said John Henry
Johnson, my executors, administrators, and' assigns, or such others as I, the
said John Henry Johnson, my executors, administrators, or 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 ROLLING METALS AND IN THE MACHINERY OR APPARATUS
EMPLOYED THEREIN," a communication to me from abroad by Hippolyte Ulysse
Petin and Jean Marie Gaudet, of the Firm of Petin, Gaudet, and Company,
of Rive de Gier, in the Empire of France; Ironmasters, upon the condition
(amongst others) that I, the said John Henry Johnson, my executors or
administrators, by an instrument in writing under my hand and seal, 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

page_text: 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 John Henry Johnson, 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, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say:
The said Invention relates to a mode of rolling T, double .T, or U shaped
metal bars and bars of a similar character as well as bars of a flat or rect-
angular section, and to the means employed therein, and consists essentially in the
employment of a pair of lateral adjustable rolls running loose on vertical axes
in combination with a pair of rolls in horizontal axes, whereby the top, bottom,
and side or sides of the bar may be rolled simultaneously. The upper roll
may be raised or lowered by screw spindles or otherwise to give any desired
thickness of metal to the rolled bar and the two lateral rolls, which revolve
loosely on their axes, and which rotate by their contact with the metal passing
between; the horizontal rolls may also be adjusted nearer to or further from
the ends of the horizontal rolls by screw spindles worked in concert or sepa-
rately, or otherwise adjusted. These several rolls will of course be shaped in
accordance with the form of bar to be produced, and any convenient arrange-
ment may be employed for giving motion to the main rolls, or, if desired, to
the lateral rolls.
And in order that the said Invention may be fully understood I shall now
proceed more particularly to describe the same, and for that purpose I shall
refer to the two Figures on the annexed Sheet of Drawings; the same letters
of reference indicating corresponding parts in both the Figures.
Figure 1 represents a sectional elevation of the improved arrangement of
rolls, and Figure 2 is a corresponding horizontal section of the same. along
the line 1, 2, in Figure 1. In the ordinary frame C are mounted the two
rolls A and A¹, which roll the metal horizontally. The upper roll A is
capable of vertical adjustment by means of the screws B and B¹. The lateral
rolls G and G¹ revolve loosely on their axes 9 and g³, which are mounted ver-
tically in jaws capable of being adjusted towards or from the ends of the rolls
A and A¹ by turning the screws D and D¹; these screws may be worked
simultaneously, if the rolls G and G¹ are required to be moved equally on
either side, or they may be operated singly. Behind the two pairs of rolls
there is fitted a guard plate E, which keeps the bar straight as it issues from
the rolls. The Drawing shows the rolls as adapted for producing a double T
iron; but it is evident that by reason of the moveability of the upper roll A

page_text: and the two lateral rolls G, G', the contour or cross section of the bar may be
considerably varied. By suitably adjusting the positions of the rolls A, A¹,
and G, G, all the different forms of flat and square bars, T bars, double T
bars, and U bars may be produced.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same. is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is, the combination of the horizontal rolls
A, A', with the lateral rolls' G, G¹, the whole: being arranged, adjusted, and
caused to operate substantially as and for the purpose herein-before described
and illustrated by the Drawings annexed.
In witness 'whereof, I, the said John Henry Johnson, have to this my
Specification set my hand and seal, the Fourth day of May, One
thousand eight hundred and sixty-seven.
J. HENRY JOHNSON. (L.B.)
