rolls, which revolve horizontally and are situate on each side of the central
vertical plane which passes transversly through the top and bottom rolls, are

passage of the metal the top roll and two horizontal rolls are moved inwards
slightly by means of powerful adjusting screws or other suitable mechanical
contrivance, so as to nip the metal equally on all four opposite sides. The
horizontal rolls are contained in strong moveable frames or supports, which are
capable of sliding vertically along the main standards or frames of the rolling
mill, so that as the top roll is lowered the two horizontal rolls may not
only be made to approach each other but to descend slightly to order
to keep them always in a central position between the top and bottom
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 11th December 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 Eleventh day of June, in the year of our Lord
One thousand eight hundred and sixty-seven, 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 AND SHAPING 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, &
Company of Rue de Gier, in the Empire of France, Ironmasters, upon

page_text: 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 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 per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Sheet of Drawings, and
to the letters and figures marked thereon, that is to say :-
This Invention relates to a peculiar combination and arrangement of rolling
mill for rolling X-shaped and other forms of pillars, girders, or bars.
According to this Invention four rolls are employed of any desired form
according to the shape of the article to be produced; the top and bottom rolls
are driven in the usual or other convenient manner, whilst the other pair of
rolls, which revolve horizontally and are situate on each side of the central
vertical plane which passes transversely through the top and bottom rolls are
rotated solely by frictional contact with the metal to be rolled. After each
passage of the metal the top roll and two horizontal rolls are moved inwards
slightly by means of powerful adjusting screws or other suitable mechanical
contrivance, so as to nip the metal equally on all four opposite sides. The
horizontal rolls are contained in strong moveable frames or supports, which
are capable of sliding vertically along the main standards or frames of the
rolling mill, so that as the top roll is lowered the two horizontal rolls
may not only be made to approach each other but to descend slightly in
order to keep them always in a central position between the top and bottom
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 shall
refer to the several Figures on the annexed Sheet of Drawings, the same
letters of reference indicating corresponding parts on all the Figures.
Figures 1 and 3 are sectional elevations of a rolling mill, shewing the rolls
of the requisite form for making bars of cruciform section adjusted to different
positions, and Figure 2 a horizontal section of the same taken on the line 1, 2,
and corresponding to the position Fig. 1.
A and A¹ are respectively the top and bottom rolls, which are driven in
any convenient manner, and G and G¹ the rolls, which revolve horizontally
on spindles 7 and 9' by frictional contact with the metal whilst undergoing

page_text: the operation of rolling. The top roll A is adjusted after each passage of the
metal by means of the screws B-and B', and the two horizontal rolls G and G¹
are adjusted by means of the screws D; D¹: .The rolls G, G¹, are contained
in the moveable frames or supports E, E', which are capable of sliding along
the main standards or frames C, C, of the rolling mill, so as to admit of
their vertical adjustment in order to keep them in a central position between
the top and bottom rolls A and A'.
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, a system of rolling or shaping metals
whereby certain compound forms or shapes are produced, such as cruciform
and multiform sections, by connecting two series of adjustable rolls in such a
manner as that two rolls acting in one plane shall be actuated upon by means
of motive power, and that the other two adjustable rolls acting at right angles
thereto shall revolve only by the frictional contact of the metal whilst undergoing
the operation of rolling.
In witness whereof, I, the said John Henry Johnson, have to this my
Specification set my hand and seal, this Eleventh day of December,
One thousand eight hundred and sixty-seven.
J. HENRY JOHNSON. (L.S.)
