IMPROVEMENTS IN THE MANUFACTURE OF PULP
Year: 1854

page_text: LETTERS PATENT to Christopher Hill, of Chippenham, in the County of
Wilts, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF PULP."
Sealed the 23rd March 1855, and dated the 2nd October 1854.
PROVISIONAL SPECIFICATION left by the said Christopher Hill at the
Office of the Commissioners of Patents, with his Petition, on the
2nd October 1854.
I, CHRISTOPHER HILL, of Chippenham, in the County of Wilts, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
PULP," to be as follows:-
This Invention has for its object better means than have heretofore been
resorted to of using vegetable matters, as well as the combination of them, in
the manufacture of paper. For this purpose the vegetable matters are at
once subjected to the action of pulping machinery, and the pulp thus obtained
from the crude vegetable matters is then boiled with a caustic alkali, and
afterwards bleached. By thus reducing the crude matters to the state of pulp
previous to boiling and bleaching, these processes are more readily and advan-
tageously performed than when the crude unreduced vegetable matters are
subjected to the boiling and bleaching processes before the same have been
reduced to pulp; and by combining the various indigenous vegetables which
abound with fibrous matter, such as the stems and roots of horse-radish, the
rush, and the flag, together with the vegetable remains from horse manure, I
obtain an abundant supply of cheap pulpy material, capable of being manu-
factured into a good serviceable paper.

by the said Christopher Hill in the Great Seal Patent Office on the
31st March 1855...
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHRISTOPHER
HILL, of Chippenham, in the County of Wilts, send greeting
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of October, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Christopher Hill, Her special licence that I, the said Christopher Hill,
my executors, adininistrators,-and-assigns,-or-such others as I, the said Chris-
topher Hill, 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 "IMPROVEMENTS IN THE MANUFACTURE OF
PULP," upon the condition (amongst others) that I, the said Christopher Hill, by
an instrument in writing under my hand and seal, 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 Christopher Hill, 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):
r
This Invention has for its object better means than have heretofore been
resorted to of using vegetable matters, as well as the combination of them, in
the manufacture of paper. For this purpose the vegetable matters are at once
subjected to the action of pulping machinery, and the pulp thus obtained from
the crude vegetable matters is then boiled with a caustic alkali, and afterwards
bleached. By thus reducing the crude matters to the state of pulp previous
to boiling and bleaching, these processes are more readily and advantageously
performed than when the crude unreduced vegetable matters are subjected to
the boiling and bleaching processes before the same have been reduced to pulp;
and by combining the various indigenous vegetables which abound with fibrous
matters, such as the stems and roots of horse-radish, the rush, and the flag,
together with the vegetable remains from horse manure, I obtain an abundant

page_text: supply of cheap pulpy material, capable of being manufactured into a good
serviceable paper.
Having thus stated the nature of my said Invention, I will proceed to
describe the manner of performing the same.
In place of bleaching the vegetable matters before reducing them to pulp,
I cause the vegetable matters which are to be used in the manufacture of
pulp for paper making to be reduced by a paper engine at the outset to a state
of pulp. For these purposes I employ the various indigenous vegetables which
abound with fibrous matters, such as the stems and roots of horse-radish, the
rush, and the flag, together with the vegetable remains of horse manure, and
having reduced such matters to the state of pulp, I cause the same to be boiled
with caustic alkali and afterwards bleached, these processes being conducted
on the pulped vegetables in the ordinary manner heretofore pursued when
boiling and bleaching like vegetable matters in the crude state, before their
reducing the same to pulp, and which are well understood.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
subjecting the vegetable matters to the pulping engine previous to bleaching
the same, and the combining the various vegetable matters of a fibrous
nature.
In witness whereof, I, the said Christopher Hill, have hereunto set my
hand and seal, this 29th day of March, in the year of our Lord One
thousand eight hundred and fifty-five.
