page_text: LETTERS PATENT to John Watson Burton, of Ipswich, and George Pye,
of the same Place, and of No. 80, Lombard Street, in the City of London,
Flax Manufacturers, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OF ROLLERS USED FOR PRESSING FABRICS, AND FIBROUS AND OTHER
MATERIALS."
Sealed the 5th March 1858, and dated the 18th September 1857.
PROVISIONAL SPECIFICATION left by the said John Watson Burton and
George Pye at the Office of the Commissioners of Patents, with their
Petition, on the 18th September 1857.
We, JOHN WATSON BURTON, of Ipswich, and GEORGE PYE, of the same
Place, and of No. 80, Lombard Street, in the City of London, Flax Manu-
facturers, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF ROLLERS USED FOR PRESSING FABRICS, AND FIBROUS AND OTHER
MATERIALS," to be as follows:-
This Invention has for its object improvements in the construction of rollers
used for pressing fabrics, and fibrous and other materials, and consists in con-
structing the exterior surfaces of such rollers of rings of the hard compounds,
produced by subjecting india-rubber, gutta percha, or mixtures thereof,
together with sulphur, to high temperatures.
The surfaces of the rollers
under the rings being coated with or composed of vulcanized india-rubber, to
give flexibility and elasticity to the inner surfaces of such hard rings.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Watson Burton and George Pye in the Great Seal
Patent Office, on the 9th March 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WATSON BURTON, of Ipswich, and GEORGE PYE, of the same Place, and of 80,
Lombard Street, in the City of London, Flax Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of September, 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 us, the
said Jolin Watson Burton and George Pye, Her special licence, that we, the
said John Watson Burton and George Pye, our executors, administrators, and
assigns, or such others as we, the said John Watson Burton and George Pye,
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 "IMPROVEMENTS IN THE CONSTRUC
TION OF ROLLERS USED FOR PRESSING FABRICS, AND FIBROUS AND OTHER MATERIALS,"
upon the condition (amongst others) that we, the said John Watson Burton,
and George Pye, our, executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one of us or
them, should particularly describe and ascertain the nature of the said Inven-
tion, 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 John Watson Burton and George Pye,
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 improvements in the construction of rollers
used for pressing fabrics and fibrous and other materials, and consists in
constructing the exterior surfaces of such rollers of rings of the hard com-
pounds produced by subjecting india-rubber, gutta percha, or mixtures thereof
together with sulphur, to high temperatures. The surfaces of the rollers
under the rings being coated with or composed of vulcanized india-rubber,
to give flexibility and elasticity to the inner surfaces of such hard rings.

page_text: Having thus stated the nature of our said Invention, we will proceed more
fully to describe the manner of performing the same.
In the construction of rollers used for pressing fabrics, and fibrous and other
materials, various substances have been used for making the rollers, such as
iron, brass, and other metals, hard wood, and other suitable substances, and in
some cases such rollers have been made in sections or rings of comparatively
small length as compared with the whole length of a complete roller, and in
the Specification of a previous Patent is described the making of rollers by
combining numerous rings of metal on an axis, having vulcanized india-rubber
interposed between the axis and the rings of metal which composed the
periphery or exterior surface of a roller, so that rollers were thereby produced
with metallic surfaces, the parts of which surfaces were rendered elastic by the
interposed vulcanized india-rubber between the inner surfaces of the metal
rings and the exterior axis on which such rings were placed; and we mention
these matters in order to state that we do not claim the construction of rollers
in several parts or sections, neither do we claim the application of vulcanized
india-rubber between the outer circumference of a roller and its axis. And
we would state that our present Invention consists in making the outer sur-
faces of rollers for pressing fabrics, and fibrous and other materials of the hard
compound of india-rubber, or of gutta percha combined with vulcanized india-
rubber interposed between the hard compound of india-rubber or of gutta
percha and the axis thereof. The rings or cylinders of the hard compound of
india-rubber or of gutta percha are produced in moulds, in like manner to what
other articles of such hard compounds of india-rubber or of gutta percha are
produced, and, as is well understood, to the process resorted to for their pro-
duction we make no claim. We would, however, state that we prefer the use of
the hard compound of india-rubber for these purposes, produced by combining
one-third by weight of sulphur and two-thirds by weight of india-rubber, and
subjected to high temperatures till the hard horny character has been obtained.
Neither do we claim the production of the cylinders of vulcanized india-rubber
which are introduced between the axes of the rollers and the hard peripheries
or circumferences of the rollers.
The thickness of the cylinders of the hard compound and the thickness of
the vulcanized india-rubber will necessarily be varied according as it is desired
to get the surface of the roller more or less elastic. When a very elastic roller
is desired, then the vulcanized india-rubber is to be thick as compared with
the outer crust or periphery of hard compound; on the other hand, when a
roller is desired to present as hard a roller as may be, then the vulcanized

page_text: india-rubber is to be comparatively thin as compared with the thickness of the
hard outer crust or periphery. Rollers thus made are to be used in like
manner to what other rollers have been, and these new compound rollers are
to be used in place of such previously used rollers.
In witness whereof, we, the said John Watson Burton and George Pye,
have hereunto set our hands and seals, this Fifth day of March, in the
year of our Lord One thousand eight hundred and fifty-eight.
Witness,
HENRY SANDHAM.
