TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ASTROP, of Jubilee Street, Stepney, in the County of Middlesex, Stationer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of January, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Astrop, Her special license that I, the said William Astrop,
my executors, administrators, and assigns, or such others as I, the said
William Astrop, my executors, administrators, or 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 MANUFACTURE OF PAPER," upon the condition (amongst
others) that I, the said William Astrop, my executors or administrators, by
an instrument in writing under my hand and seal, or under the hand and
seal of one of them, 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 I, the said William Astrop, do hereby declare
the nature of my 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:-
:-
My said Invention consists in the employment of the fibrous portions of the
roots of parsnips, carrots, and turnips of all kinds, and of the roots, stems, and
stalks of beet, mangold wurtzel, chicory, and rhubarb plants, also of the fibre
of the cocoa-nut, and leaves of the orange plant, and flags or reeds, also horse
and cattle manure, for the manufacture of "half stuff" and pulp to be used in
the production of paper and cardboard, the substances or materials herein-
before enumerated being employed either separately or in any combination
with each other or with any of the ordinary pulp now used in the manufacture
of paper and cardboard.

page_text: In preparing the roots, stems, stalks, and leaves of plants for their manu-
facture into "half stuff" or pulp, I first wash them thoroughly and cut off
or otherwise remove any decayed or extraneous matter, I then extract or expel
all the juice therefrom by pressure, and afterwards wash the solid matter
or pulp, boil it in alkali, and finally bleach it in the ordinary well known
manner.
In treating manures, I first free them from ammonia by any well known
process, and then wash them well in a suitable apparatus in order to remove
any dirt, animal, or other extraneous matter therefrom, after which they are
boiled in alkali and bleached in the usual manner.
I may here observe that I do not confine or restrict myself to these peculiar
modes of treating the herein-before enumerated substances, but by adopting
such modes of treatment good results will be obtained.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent, is, the application and use to and in the manufacture of
"half stuff," and pulp for the production of paper and cardboard of any one or
more of the substances herein-before mentioned in combination or not with
ordinary pulps.
In witness whereof, I, the said William Astrop, have hereunto set
my hand and seal, this Third day of July One thousand eight hundred
and sixty-three.
