Year: 1866

page_text: LETTERS PATENT to William Henry Barlow, of Great George Street,
Westminster, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF RAILWAY BARS."
Sealed the 27th April 1866, and dated the 26th January 1866.
PROVISIONAL SPECIFICATION left by the said William Henry Barlow
at the Office of the Commissioners of Patents, with his Petition, on
the 26th January 1866.
I, WILLIAM HENRY BARLOW, of Great George Street, Westminster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF RAILWAY BARS," to be as follows:-
This Invention has for its object improvements in the manufacture of
railway bars. For these purposes in constructing railway bars partly of steel
and partly of iron, the steel is first rolled or formed with a flange or flanges
and web corresponding to the section of rail desired to be made, whether for a
double-headed rail of the ordinary construction or for a contractor's rail. The
channels or hollow spaces on each side of the web which joins the two heads
or flanges of a double-headed rail, or which joins the head and foot of a con
tractor's rail, are to have bars of iron introduced, and the rail is then to be
finished by rolling to produce the length and section desired. By these means
the two heads or flanges of a double-headed rail, or the one head and foot of
a contractor's rail, may be composed of steel (either partly or entirely) and

by the said William Henry Barlow in the Great Seal Patent Office
on the 25th July 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY BARLOW, of Great George Street, Westminster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of January, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Henry Barlow, Her special licence that I, the said William
Henry Barlow, my executors, administrators, and assigns, or such others as I,
the said William Henry Barlow, 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 "IMPROVE-
MENTS IN THE MANUFACTURE OF RAILWAY BARS," upon the condition (amongst
others) that I, the said William Henry Barlow, my executors or adminis-
trators, 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 immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Henry Barlow, 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 thereof, that is to say :-
This Invention has for its object improvenients in the manufacture of
railway bars. For these purposes in constructing railway bars partly of steel
and partly of iron, the steel is first rolled or formed with a flange or flanges
and web corresponding to the section of rail desired to be made, whether for a
double-headed rail of the ordinary construction or for a contractor's rail. The
channels or hollow spaces on each side of the web which joins the two heads
or flanges of a double-headed rail, or which joins the head and foot of a con-

page_text: finished by rolling to produce the length and section desired. By these means
the two heads or flanges of a double-headed rail, or the one head and foot of a
contractor's rail, may be composed of steel (either partly or entirely), and
connected together by a web of the same material, whilst the two sides of the
rail will be of iron.
Having thus stated the nature of my Invention, I will proceed more fully
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an end view of an ingot mould c, c, in which fluid cast
steel a, a, is run, having placed in such moulds two pieces b, b, of wrought
iron; or the casting a, a, of steel may be made separate from the wrought
iron, and the wrought-iron pieces b, b, introduced before rolling the parts into
a rail.
Figure 2 shows an end view or transverse section of a rolled or otherwise
forged or formed bar of steel a, a, into which two bars of wrought iron b, b,
are introduced before completing the rolling into a railway bar of a tranverse
section, such as is shown in Figure 3. If in place of the complete rail being
of the section Figure 3 a contractor's rail be desired, then in place of the foot
being essentially of steel, as shown in the Drawings, Figure 3, it is preferred
that the quantity of the steel in the head should be retained whilst the steel in
the foot should be considerably less than what is in the head. I would remark
that the proportions of iron and steel may be varied from what are shown.
The combined parts a, a, and b, b, of Figures 1 or 2, are heated and rolled to
produce the length and the cross section of rail desired.
The peculiarity of the Invention consists in first forming by casting, rolling,
or otherwise, steel with a web and flanges, or a flange corresponding in section
with the intended rail, and then rolling the same together with wrought iron
on either side, as above described.
In witness whereof, I, the said William Henry Barlow, have hereunto
set my hand and seal, this Twenty-third day of July, in the year of our
Lord Oue thousand eight hundred and sixty-six.
WILLIAM HENRY BARLOW. (L.B.)
