IMPROVEMENTS IN MATERIALS FOR THE MANUFACTURE OF PAPER, ALSO APPLICABLE FOR OTHER PURPOSES.” PROVISIONAL SPECIFICATION
Year: 1870

page_text: LETTERS PATENT to Augustus Henry Thurgar, of the Parish of
Lakenham, in the County of the City of Norwich, and Charles
Henry Capon, of Thorpe Hamlet, also in the County of the City of
Norwich, for the Invention of "IMPROVEMENTS IN MATERIALS FOR THE
MANUFACTURE OF PAPER, ALSO APPLICABLE FOR OTHER PURPOSES.”
PROVISIONAL SPECIFICATION left by the said Augustus Henry Thurgar
and Charles Henry Capon at the Office of the Commissioners of
Patents, with their Petition, on the 28th December 1870.
We, AUGUSTUS HENRY THURGAR, of the Parish of Lakenham, in the
County of the City of Norwich, and Charles HENRY CAPON, of Thorpe
Hamlet, also in the County of the City of Norwich, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MATERIALS FOR
THE MANUFACTURE OF PAPER, ALSO APPLICABLE FOR OTHER PURPOSES," to be as
follows, that is to say :-
Our Invention consists in the employment of the cottony and fibrous
parts of the following plants, videlicet, those known as the cineraria
maritima, or sea ragwort, the gnaphalium tomentosum, the centaurea

page_text: gymnocarpa, and other plants of the same families, either alone or in
combination with the fibres of cotton or linen rags and other suitable
vegetable fibres, such as straw and esparto grass for the manufacture by
the ordinary processes of paper and of those articles such as pasteboard
and papier maché for the manufacture of which the materials for paper
making are now employed. When these materials are combined we
employ them in the proportions of about one part of the fibres of cotton
or linen rags to three parts of the cottony and fibrous parts of the
said plants.
The process of making paper from the above described new plant
fibres is as follows.-The plants are dried at the usual temperature,
soaked in cold water for several hours when used, then reduced to a pulp
by a bruising or jamming and grinding process, and boiled with the
usual chemicals for bleaching. The paper thus produced is good
ordinary paper, but to incrcase its strength for fine sorts a mixture with
cotton fibre of about one-fourth of cotton to three-fourths of the fibre
of the plants is used.
The fibres of the said plants may also be employed alone as a sub-
_stitute for cotton or in combination with cotton or wool in the manu-
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Augustus Henry Thurgar and Charles Henry Capon
in the Great Seal Patent Office on the 24th June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, AUGUSTUS
HENRY THURGAR, of the Parish of Lakenham, in the County of the City
of Norwich, and CHARLES HENRY CAPON, of Thorpe Hamlet, also in
the County of the City of Norwich, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of December, in
the year of our Lord One thousand eight hundred and seventy, in
the thirty-fourth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said Augustus Henry Thurgar
and Charles Henry Capon, Her special licence that we, the said Augustus
Henry Thurgar and Charles Henry Capon, our executors, administrators,
and assigns, or such others as we, the said
executors, administrators, and assigns,

page_text: 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 MATERIALS FOR THE MANUFACTURE OF
PAPER, ALSO APPLICABLE FOR OTHER PURPOSES," upon the condition (amongst
others) that we, the said Augustus Henry Thurgar and Charles Henry
Capon, our executors or administrators, by an instrument in writing
under 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.
NOW KNOW YE, that we, the said Augustus Henry Thurgar and
Charles Henry Capon, do hereby declare the nature of our said Inven-
tion, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, that is to
say:-
Our Invention consists in the employment of the cottony and fibrous
parts of the following plants, videlicet, those known as the cineraria
maritima, or sea ragwort, the gnaphalium tomentosum or cudweed, and
other plants of the same families, either alone or in combination with
the fibres of cotton or linen rags and other suitable vegetable fibres,
such as straw and esparto grass for the manufacture by the ordinary
processes of paper and of those articles such as pasteboard and papier
maché for the manufacture of which the materials for making paper
are now employed. When these materials are combined we employ
them in the proportion of about one-third of the fibres of cotton or
linen rags to about two-thirds of the cottony and fibrous parts of the
said plants.
One of the processes by which paper may be made from the above
described new plant fibres is as follows:-The plants are dried at the
usual temperature, soaked in cold water for several hours when used,
then reduced to a pulp by a jamming and tearing process and boiled and
treated with the usual chemicals for bleaching. The paper thus produced
is good ordinary paper, but to increase its strength for fine sorts a
mixture with cotton fibre of about one-third of cotton to about two-thirds
of the fibre of the plants is used.

page_text: The fibres of the said plants may also be employed alone as a substitute
for cotton or in combination with cotton or wool in the manufacture of
felt by the ordinary process.
Having now described our Invention, what we claim is,-
Firstly. The manufacture of paper, pasteboard, and papier maché with
pulp obtained from the plants known as the cineraria maritima, or sea
ragwort, the gnaphalium tomentosum or cudweed, and other plants of
the same families either alone or in combination with other paper making
materials substantially as herein-before described.
Secondly. The employment of the fibres of the said plants alone as a
substitute for cotton or in combination with cotton or wool in the
manufacture of felt.
In witness whereof, we, the said Augustus Henry Thurgar and
Charles Henry Capon, have hereto set our hands and seals, this
Twenty-second day of June, in the year of our Lord One thousand
eight hundred and seventy-one.
