IMPROVEMENTS IN THE MANUFACTURE OF IRON FOR PLATING VESSELS AND FORTIFICATIONS, AND THE FASTENINGS CONNECTED THEREWITH
Year: 1868

page_text: LETTERS PATENT to Joshua Jeavons, of the Atlas Works, Sheffield, in
the County of York, Forge Manager, and Charles Martin,. of
Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF IRON FOR PLATING
VESSELS AND FORTIFICATIONS, AND THE FASTENINGS CONNECTED THEREWITH."
Sealed the 23rd February 1869, and dated the 25th August 1868.
PROVISIONAL SPECIFICATION left by the said Joshua Jeavons and
Charles Martin at the Office of the Commissioners of Patents, with
their Petition, on the 25th August 1868.
We, JOSHUA JEAVONS, of the Atlas Works, Sheffield, in the County of
York, Forge Manager, and CHARLES MARTIN, of Chancery Lane, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF IRON FOR PLATING,

page_text: VESSELS AND FORTIFICATIONS, AND THE FASTENINGS CONNECTED THEREWITH," to be
as follows:-
This Invention consists in certain improvements whereby iron of a
fibrous character fitted for plating ships and other vessels and fortifi-
cations, and for the fastenings employed for such purposes, is produced
of a quality superior to that hitherto employed. Iron of any of the
ordinary English brands either refined, or by preference non-refined
siliceous iron is taken and combined with titanic iron produced from
titaniferous ores (such, for instance, as ilmenite) in the puddling furnace,
and afterwards piled in the ordinary manner until the necessary degree
of fibrous structure is obtained, the plates being rolled in the way
usually adopted. For bolts, bars, and other articles which are subject to
violent tensile strains blooms composed of about one-fourth of titanic
iron of good quality blended with about three-fourths of iron of
ordinary English brands are employed. The proportions before men-
tioned are, however, approximate only, as they must necessarily vary
with the nature and quality of the materials used.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joshua Jeavons and Charles Martin in the Great
Seal Patent Office on the 24th February 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JosшUA
JEAVONS, of the Atlas Works, Sheffield, in the County of York, Forge
Manager, and CHARLES MARTIN, of Chancery Lane, in the County of
Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of August, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Joshua Jeavons and Charles Martin, Her
special licence that we, the said Joshua Jeavons and Charles Martin, our
executors, administrators, and assigns, or such others as we, the said
Joshua Jeavons and Charles Martin, our executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,

page_text: 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
IRON FOR PLATING VESSELS AND FORTIFICATIONS, AND THE FASTENINGS CONNECTED
THEREWITH," upon the condition (amongst others) that we, the said
Joshua Jeavons and Charles Martin, our executors or administrators,
by an instrument in writing under our, or their, or one of their
hands and seals, 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 we, the said Joshua Jeavons and Charles
Martin, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to
say:
Our said Invention consists in certain improvements whereby iron of
a fibrous character fitted for plating ships and other vessels and fortifi-
cations, and for the fastenings employed for such purposes, is produced
of a quality superior to that hitherto employed. Iron of any of the
ordinary English brands either refined, or by preference non-refined
siliceous iron is taken and combined with titanic iron obtained from
titaniferous ores (such, for instance, as ilmenite) in the puddling
furnace, and afterwards piled in the ordinary manner until the necessary
degree of fibrous structure is produced, the plates being rolled in the
usual manner. For bolts, bars, and other articles which are subject to
violent tensile strains blooms composed of about one-fourth of titanic
iron of good quality blended with about three-fourths of iron of ordinary
English or other brands are employed. The proportions before men-
tioned are, however, approximate only, as they must necessarily vary
with the nature and quality of the materials used.
Having thus declared and ascertained the nature of our said
Invention, and the manner in which it is to be performed, we would
observe in conclusion that what we consider novel and original, and
therefore claim as constituting the Invention secured to us by the
said herein-before in part recited Letters Patent is, the combination

page_text: of titanic iron with iron of ordinary English and other brands as and
for the purposes herein-before mentioned.
In witness whereof, I, the said Joshua Jeavons, have, on behalf
of myself and the said Charles Martin, set my hand and seal,
this Twenty-third day of February, in the year of our Lord
One thousand eight hundred and sixty-nine.
JOSHUA JEAVONS. (L.s.)
