AN IMPROVED METHOD OF MANUFACTURING FIGURED IRON AND STEEL
Year: 1873

page_text: LETTERS PATENT to Homan Price Fenby, of No. 13, Queen's Square,
Leeds, in the County of York, Mechanical Engineer, for the
Invention of "AN IMPROVED METHOD OF MANUFACTURING FIGURED IRON
AND STEEL,"
Sealed the 28th April 1874, and dated the 4th November 1873.
PROVISIONAL SPECIFICATION left by the said Homan Prico Fenby at
the Office of the Commissioners of Patents, with his Petition, on
the 4th November 1873.
I, HOMAN PRICE FENBY, of No. 13, Queen's Square, Leeds, in the
County of York, Mechanical Engineer, do hereby declare the nature of
the said Invention for "AN IMPROVED METHOD OF MANUFACTURING FIGURED
IRON AND STEEL," to be as follows:-
My Invention consists in an improved method of manufacturing that
kind of iron and steel commonly called figured iron and steel, chiefly
used for fire-arms, and my objects are the production of various patterns
of figuring by simpler means than have hitherto been employed for that

page_text: purpose, and also the production of tubes, bars, and masses of figured
metal without welded seams.
For carrying my said Invention into practise I use wires, strips, or
bands of iron or steel, or both, coiled, twisted, or interlaced regularly or
irregularly, and weld them into a mass, to be afterwards rolled or forged
into the shape required. In coiling, twisting, or interlacing these wires,
strips, or bands I prefer to use alternate strands of different degrees of
carbonization.
One method of producing bars according to my Invention is to cover
an iron or steel core with the aforesaid coiled, twisted, or interlaced 1
wires, strips, or bands, so as to produce when they are welded together
a perfect coating of figured iron over the core.
Another of my methods is to coil, twist, or interlace the aforesaid
wires, strips, or bands in long lengths, which I afterwards shear into
short pieces. These short picces I place in a crucible or other suitable 1
receptacle, and raise the whole to a welding heat, and then forge or roll
the mass to the shape required.
In making tubes I sometimes drill or bore out the centre of the solid
bar of figured metal, or drill out the aforesaid iron or steel core.
According to another method of producing tubes according to my 2
Invention, I coil, twist, or interlace the aforesaid wires, strips, or bands
into the form of a tube, which I raise to a welding heat and then forge
or roll on a mandril till the tube is thoroughly welded. This mandril is
afterwards withdrawn by hammering the tube when cold until it is
sufficiently expanded to set the mandril free.
The tubes made according to any of these different methods may be
2
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Homan Price Fenby in the Great Seal Patent
Office on the 2nd May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HOMAN
PRICE FENBY, of No. 13, Queen's Square, Leeds, in the County of York,
Mechanical Engineer, send greeting.

Letters Patent, bearing date the Fourth day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Homan Price Fenby, Her
special licence that I, the said Homan Price Fenby, my executors,
administrators, and assigns, or such others as I, the said Homan Price
Fenby, my 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, 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
"AN IMPROVED METHOD OF MANUFACTURING FIGURED IRON AND STEEL," upon the
condition (amongst others) that I, the said Homan Price Fenby, 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 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Homan Price Fenby, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-
My Invention consists in an improved method of manufacturing that
kind of iron and steel commonly called figured iron and steel, and
chiefly used for fire-arms, and my objects are the production of various
patterns of figuring by simpler means than have hitherto been employed
for that purpose, and also the production of tubes, bars, and masses of
figured metal without welded seams.
For carrying my said Invention into practice I use wires, strips, or
bands of iron or steel, or both, coiled, twisted, or interlaced regularly or
irregularly, and weld them into a mass, to be afterwards rolled or forged
into the shape required. In coiling, twisting, or interlacing these wires,
strips, or bands I prefer to use alternate strands of different degrees of
carbonization.
One process of producing bars according to my Invention is to cover

perfect coating of figured iron over the core.
Another of my processes is to coil, twist, or interlace the aforesaid
wires, strips, or bands in long lengths, which I afterwards shear into
short pieces. These short pieces I place in a crucible or other suitable
receptacle, and raise the whole to a welding heat, and then forge or roll
the mass to the shape required.
In making tubes I sometimes drill or bore out the centre of the solid
bar of figured metal, or drill out the aforesaid iron or steel core.
Another process of producing tubes according to my Invention is to
coil, twist, or interlace the aforesaid wires, strips, or bands into the form
of a tube, which I raise to a welding heat, and then forge or roll on a
mandril till the tube is thoroughly welded. The mandril may afterwards
be withdrawn by hammering the tube when cold, until it is sufficiently
expanded to set the mandril free.
The tubes made according to any of these different processes may be
afterwards rolled or forged to greater lengths and different diameters.
Having thus described my said Invention, and the manner of per-
forming the same, I wish it understood that I claim, the improved
method of manufacturing figured iron and steel, as herein set forth.
In witness whereof, I, the said Homan Price Fenby, have hereunto
set my hand and seal, this First day of May, in the year of our
Lord One thousand eight hundred and seventy-four.
