IMPROVEMENTS IN THE PRE- PARATION AND TREATMENT OF FLAX AND OTHER FIBROUS MATERIALS TO BE SUBSEQUENTLY OPERATED UPON BY MACHINERY EMPLOYED FOR PREPARING AND SPINNING COTTON."
Year: 1862

page_text: LETTERS PATENT to Robert Raynsford Jackson and Æmilius Irving
Jackson, both of Blackburn, in the County of Lancaster, Cotton Spinners
and Manufacturers, for the Invention of "IMPROVEMENTS IN THE PRE-
PARATION AND TREATMENT OF FLAX AND OTHER FIBROUS MATERIALS TO BE
SUBSEQUENTLY OPERATED UPON BY MACHINERY EMPLOYED FOR PREPARING AND
SPINNING COTTON."'
Sealed the 17th March 1863, and dated the 24th September 1862.
PROVISIONAL SPECIFICATION left by the said Robert Raynsford Jackson
and Æmilius Irving Jackson at the Office of the Commissioners of
Patents, with their Petition, on the 24th September 1862.
We, ROBERT RAYNSFORD JACKSON and ŒMILIUS IRVING JACKSON, both of
Blackburn, in the County of Lancaster, Cotton Spinners and Manufacturers,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
PREPARATION AND TREATMENT OF FLAX AND OTHER FIBROUS MATERIALS TO BE
SUBSEQUENTLY OPERATED UPON BY MACHINERY EMPLOYED FOR PREPARING AND
SPINNING COTTON," to be as follows:-
Firstly, our Invention has for its object the preparation and treatment of
such fibrous material as is generally of longer staple than cotton fibre, so that
such prepared fibrous material may be subsequently operated upon either
alone or in combination with cotton or other fibrous material by such
machinery as that commonly used for preparing, spinning, and weaving cotton
alone; and our Invention consists, first, in preparing the fibrous material so as
to be submitted to a carding process by any ordinary means, then carding
the material, then operating upon the carded sliver by gill combs to still
further straighten the fibres if required, next forming the slivers into a
lap or sheet by 'means of the Derby doubler or other suitable machine, and

page_text: then cutting the laps or sheets into short lengths, in which state the material
can be operated upon in the ordinary cotton machinery.
The material if required may be bleached or otherwise chymically treated
either before or after the above process, or both before and after if required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Raynsford Jackson and Emilius Irving Jackson in
the Great Seal Patent Office on the 24th March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
RAYNSFORD JACKSON and ÆMILIUS IRVING JACKSON, both of Blackburn, in the
County of Lancaster, Cotton Spinners and Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of September, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Robert Raynsford Jackson and Æmilius Irving Jackson, Her special
license that we, the said Robert Raynsford Jackson and Emilius Irving
Jackson, our executors, administrators, and assigns, or such others as we, the
said Robert Raynsford Jackson and Æmilius Irving Jackson, 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 PREPARATION AND TREATMENT OF
FLAX AND OTHER FIBROUS MATERIALS TO BE SUBSEQUENTLY OPERATED UPON BY
MACHINERY EMPLOYED FOR PREPARING AND SPINNING COTTON," upon the condition
(amongst others) that we, the said Robert Raynsford Jackson and Æmilius
Irving Jackson, by an instrument in writing under our hands and seals, (or
under the hand and seal of one of us,) should particularly describe and
ascertain the nature of the said Invention, and in what nianner 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 Robert Raynsford Jackson and Æmilius
Irving Jackson, 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 (that is to say):-

page_text: Our Invention has for its object the preparation and treatment of such
fibrous material as is generally of longer staple than cotton fibre, so that such
prepared fibrous material may be subsequently operated upon either alone or
in combination with cotton or other fibrous material by such machinery as
that commonly used for preparing, spinning, and weaving cotton alone; and
our Invention consists, first, in preparing flax, tow, or other fibrous material
so as to be submitted to a carding process by any ordinary means, sometimes
only to the extent necessary to feed it to the tow card, and then carding the
material, then operating upon the carded material by "gill" drawing combs
to still further straighten the fibres if required, next forming the material into
a lap or sheet by means of a "Derby doubler" or other suitable machine, and
then cutting the Japs or sheets into short lengths by a machine similar to that
described in the Specification of a Patent granted to us on the Twenty-fourth
day of September, in the year of our Lord One thousand eight hundred and
sixty-two, and numbered 2608, or any other suitable machine. When the
fibrous material has undergone these processes it is ready to be operated upon
alone or in combination with cotton in ordinary preparing and spinning
machinery for operating upon cotton fibre.
The material if required may be bleached or otherwise chemically treated
either before or after or in any of the intermediate stages of the process above
described.
We have now particularly described the nature of our Invention and the
mode of carrying the same into effect, and wish it to be understood that we
claim as our Invention the combination and order of the processes for pre-
paring and treating flax and other fibrous materials, so as to be subsequently
operated upon either alone or when mixed with cotton by machinery for
preparing and spinning cotton, as herein-before described.
In witness whereof, we, the said Robert Raynsford Jackson and Æmilius
Irving Jackson, have hereunto set our hands and seals, this Twenty-
first day of March, in the year of our Lord One thousand eight
hundred and sixty-three.
ROBERT RAYNSFORD JACKSON. (L.S.)
EMILIUS IRVING JACKSON.
