A NEW OR IMPROVED MANUFACTURE OF ROLLERS OR CYLINDERS FOR PRINTING FABRICS
Year: 1857

page_text: LETTERS PATENT to Richard Ford Sturges, of Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "A NEW OR
IMPROVED MANUFACTURE OF ROLLERS OR CYLINDERS FOR PRINTING FABRICS."
Sealed the 8th June 1858, and dated the 21st December 1857.
PROVISIONAL SPECIFICATION left by the said Richard Ford Sturges
at the Office of the Commissioners of Patents, with his Petition, on the
21st December 1857.
I, RICHARD FORD STURGES, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for "A
NEW OR IMPROVED MANUFACTURE OF ROLLERS OR CYLINDERS FOR PRINTING FABRICS,"
to be as follows:-
My said Invention consists in manufacturing rollers or cylinders for printing
fabrics by casting in the interior of a tube of copper or alloy of copper a
hollow cylinder of cast iron. I carry my Invention into effect in the following
manner: I take the tube or hollow cylinder of copper or alloy of copper,
which it is intended shall form the exterior or printing surface of the roller or
cylinder to be manufactured, and I place the said copper tube in a vertical
position. I fix temporarily in the axis of the copper tube a rod or mandril,
of a size similar to that of the axis on which the finished roller is to be placed
when used. I close the lower end of the tube by a ring of iron or other
suitable metal, the said ring filling the bottom of the annular space between
the copper tube and the rod or mandril. I then pour fused cast iron into the

page_text: annular space between the copper tube and the rod or mandril, so as to fill
the said space with the said fused cast iron. I allow the whole to cool, and
then remove the rod or mandril from the axis of the roller or cylinder. There
is thus produced a roller or cylinder composed of a tube of copper or alloy of
copper, supported by an internal support or hollow cylinder of cast iron, the
said hollow cylinder of cast iron having been cast in the interior of the copper
tube by fused cast iron having been poured into the space between the interior
of the said tube and a rod or mandril temporarily supported in the axis of the
said tube.
The roller or cylinder may be finished by turning or otherwise, and engraved
in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Ford Sturges in the Great Seal Patent Offico
on the 18th June 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
FORD STURGES, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of December, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twenty-first year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Richard Ford Sturges, Iler special licenco that I, the said
Richard Ford Sturges, my executors, administrators, and assigns, or such
others as I, the said Richard Ford Sturges, 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
"A NEW ON IMPROVED MANUFACTURE OF ROLLERS OR CYLINDERS FOR PRINTING
FABRICS," upon the condition (amongst others), that I, tho said Richard Ford
Sturges, 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 immediately after the date of the
said Letters Patent.

page_text: NOW KNOW YE, that I, the said Richard Ford Sturges, 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 :-
My said Invention consists in manufacturing rollers or cylinders for printing
fabrics by casting in the interior of a tube of copper or alloy of copper a
hollow cylinder of cast iron, as hercin-after explained, and illustrated in the
accompanying Drawing.
In carrying my Invention into effect, I take a tube or hollow cylinder of
copper or alloy of copper, shown in section at a in Figure 1. The said tube
is of a size suitable to form the exterior or printing surface of the roller
or cylinder to be manufactured. I place the said copper or copper alloy
tube a in a vertical position, and I fix temporarily in the axis of the said
'tube a a rod or mandril b, of a size and figure similar to the size and figure
of the axis on which the finished roller or cylinder is to be placed when used.
A groove or depression c is cut along the whole length of the mandril 6 when
it is intended to fix the finished roller on its axis by a "nib" in the interior of
the roller engaging in a slot on the mandril similar to the slot c. The lower
end of the tube a is closed by means of a ring of iron or other suitable metal
d, the said ring d occupying the bottom of the annular space between the
copper tube a and the rod or mandril b. The several parts a, b, and a being
in the positions described and represented in Figure 1, I pour fused cast iron
into the annular space between the copper tube a and the rod or mandril 6,
filling the said space with the said fused cast iron. I allow the whole to cool,
and then remove the rod or mandril 6 from the axis of the roller or cylinder.
The said mandril 6 is slightly taper, and may be removed by a few blows from
a hammer.
By the process described there is produced a roller or cylinder such as
is represented in section in Figure 2, the said roller or cylinder, Figure 2, con-
sisting of a tube of copper or alloy of copper a, supported by an internal
support or hollow cylinder of cast iron e, the said hollow cylinder of cast iron e
having been cast in the interior of the copper tube a by fused cast iron having
been poured into the space between the interior of the said tube and a rod or
mandril supported in the axis of the said tube. The inner surface of the
copper tube a may have one or more ribs or elevations thereon, so as to cause
the iron cast in the said tube to fix itself more securely thereto. The roller
or cylinder, Figure 2, may be finished by turning or otherwise, and engraved in
the ordinary manner.
I have not thought it necessary to describe in detail the method of casting

page_text: the hollow cylinder of cast iron c in the interior of the copper tubo a, as no
special instructions are required to enable a workman acquainted with the
ordinary process of casting iron to effect the casting of the said hollow cylinder e
in the copper tube a.
Having now described the nature of my Invention, and the manner of carry-
ing the same into effect, I wish it to be understood that I do not limit myself
to the precise details herein described, as the same may be varied without
departing from the nature of my said Invention; but I claim as my Invention
the new or improved manufacture of rollers or cylinders for printing fabrics
herein described, and illustrated in the accompanying Drawing, that is to say,
making the said rollers or cylinders by casting a hollow cylinder of cast iron
in the interior of a tube of copper or alloy of copper.
In witness whereof, I, the said Richard Ford Sturges, have hercunto
set my hand and seal, this Seventeenth day of June, in the year of
our Lord One thousand eight-hundred and fifty-eight.
Witness,
GEORGE SHAW.
