AN IMPROVED MODE OF CUTTING UP
Year: 1867

page_text: LETTERS PATENT to John Dyson and George Walter Dyson, both of
Tinsley, in the County of York, and Stephen Martin, of Sheffield, in the
same County, for the Invention of "AN IMPROVED MODE OF CUTTING UP

page_text: Now the object of our Invention is so to cut single and double headed
rails and rail ends that the pieces may afterwards be rolled into small rods
or wires without appreciable waste. For this purpose we cut the rails
longitudinally by circular cutters at two points, that is to say, at each end of
the web, whereby we obtain three bars composed respectively of the head,
the web, and the bottom or second head; each of these pieces can then be
rolled by ordinary machinery into rods or wires. The circular cutters are
adjustable on their shafts by collars and washers according to the size and
section of rail to be acted upon.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Dyson, George Walter Dyson, and Stephen Martin
in the Great Seal Patent Office on the 29th February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
DYSON and GEORGE WALTER DYSON, both of Tinsley, in the County of York,
and STEPHEN MARTIN, of Sheffield, in the same County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent,, bearing date the Twenty-ninth day of August, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of. Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Jolin Dyson, George Walter Dyson, and Stephen Martin, Her
special licence, that we, the said John Dyson, George Walter Dyson, and
Stephen Martin, our executors, administrators, and assigns, or such others
as we, the said John Dyson, George Walter Dyson, and Stephen 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, .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 MODE OF CUTTING UP
IRON AND STEEL RAILS AND RAIL ENDS IN ORDER TO UTILIZE THEM," upon the
condition (amongst others) that we, the said John Dyson, George Walter
Dyson, and Stephen Martin, or one of us, our executors or administrators, by
an instrument in writing under our, or one of 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.

page_text: NOW KNOW IE, that we, the said John Dyson, George Walter Dyson,
and Stephen 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 thereof, reference being had
to the Drawings hereunto annexed, that is to say:-
Our Invention relates to the cutting up of iron and steel single headed and
double headed rails and rail ends; single headed rails bave hitherto been
cut up into pieces for melting, while double headed rails have sometimes been
cut up in the same way, and the greater portion thereby rendered useless
except for scrap.
Now the object of our Invention is so to cut up single and double headed
rails and rail ends that the pieces may afterwards be rolled into small rods or
wires without appreciable waste. For this purpose we cut; the rails longi-
tudinally by circular cutters at two points, that is to say, at each end of the
web, whereby we obtain three bars, composed respectively of the head, the
web, and the bottom or second head; each of these pieces can then be rolled
by ordinary machinery into rods or wires. The circular cutters are adjustable
on their shafts by collars and washers according to the size and section of rail
to be acted upon. They are made of chilled metal, and turned up to the
desired form; or the cutting apparatus may consist of a wrought or cast iron
or steel shaft with collars and steel cutters bolted thereto, and regulated by
washers according to the section of the rails or rail ends to be cut.
Our Invention will be fully understood by the accompanying Drawings.
Figure 1 represents a single headed or flat bottomed rail, and Figure 2
represents the same after it has been cut by the cutters shown in Figure 3 ;
Figure 4 represents a double headed rail, and Figure 5 represents the same
after it bas been cut by the cutters shown in Figure 6. In some cases we
make the cutters or rolls of such form that they roll the bead or the bottom,
or both the head and the bottom, into square and flat bars at the same time
that they slit or cut the rails. Figure 7 represents a pair of rolls or cutters
which will cut and roll the single beaded rail shown in Figure 1 into the form
represented in Figure 8; and Figure 9 represents a pair of rolls or cutters
which will cut and roll the double headed rail shown in Figure 4 into the
form represented in Figure 10. The cutters or rollers may be driven by any
convenient arrangement.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim, the cutting up
of iron and steel-rails-and-rails-ends longitudinally at each end of the web by

before describe:l.
In witness whereof, we, the said John 'Dyson, George Walter Dyson,
and Stephen Martin, have hereunto set our bands and seals, this
Twenty-eighth day of February One thousand eight hundred and
