Year: 1854

page_text: LETTERS PATENT to Henry Diaper, of Saint Michael's Terrace, Pimlico,
in the County of Middlesex, Gentleman, for the Invention of "THE
PROVISIONAL SPECIFICATION left by the said Henry Diaper at the
Office of the Commissioners of Patents, with his Petition, on the
20th November 1854.
I, HENRY DIAPER, do. hereby declare the nature of the said Invention for
"THE APPLICATION OF A NEW MATERIAL TO THE MANUFACTURE OF PAPER" to be
as follows:-
.1
I employ the residue left after the extraction of the oil from the white
portion of the coco or coker nut; I separate any small portion of oil which
remains in this residue by means of alkali or otherwise, and I reduce the
residue to the state of pulp; I employ this pulp, either alone or mixed
with the pulp obtained froin rags or other substances, in the manufacture
of paper.
"

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, file
by the said Henry Diaper in the Great Seal Patent Office on the
18th May 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
DIAPER, of Saint Michael's Terrace, Pimlico, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty, Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of November, 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 Henry Diaper, Her special licence that I, the said Henry Diaper, my
executors, administrators, and assigns, or such others as I, the said Henry
Diaper, 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 "THE APPLICATION OF
A NEW MATERIAL TO THE MANUFACTURE OF PAPER," upon the condition (amongst
others) that I, the said Henry Diaper, 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 Henry Diaper, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained .in and by the following
statement thereof (that is to say) :-
-I-employ the-residue-left-after-the-extraction-of-the-oil-from-the-white-
portion of the coco or coker nut; I separate any small portion of oil which
remains in this residue by means of alkali or otherwise, and I reduce the
residue to the state of pulp; I employ this pulp, either alone or mixed
with the pulp obtained from rags or other substances, in the manufacture
of paper.
The coco-nut kernel is first separated from its shell, and its exterior is then
pared, to free it from any of the brown covering by which the kernel is attached
to the shell; it is then crushed, and treated in the ordinary manner practised
for extracting the coco-nut oil. The-residue of the coco-nut kernel after this'
treatment is broken up or reduced to small particles, by rollers or otherwise,

page_text: by which means the remaining portion of the oil that is attached to the cells
may be more easily abstracted. This is effected by placing it in water, and
heating it by a water bath or otherwise, by which means the oil is gradually
separated from the fibrous matter of the kernel, and rises to the top of the
water, from whence it is drawn off or removed. The fibre is now in a fit state
to be converted into pulp for some descriptions of paper, such as brown paper
or millboard, in which the small remaining. portion of oil is not injurious.
When, however, it is required to remove this last portion of oil, the fibrous
material is well washed in water containing a portion of alkali or other.
detergent until the oil is removed, and the materal is then adapted for making
pulp for white paper. The fibrous matter of the coco-nut kernel being thus
freed from oil, may be dried and packed for transit. This prepared fibre is
converted into pulp by beating or reducing it in a beating machine, and it
may either be used alone, or beaten up and amalgamated with cotton or linen,
or other fibre, and such simple or compound pulp is made into paper by the
ordinary means. When the pulp is to be used in the manufacture of coarse
papers, such as brown paper, whited-brown paper, pasteboard, or millboard, it
is not necessary to pare the exterior of the kernels before extracting the oil
from them, as herein-before mentioned.
Having now described the nature of my Invention, and in what manner
the same is to be performed, I wish it to be understood that what I claim
is, the application of the coco-nut kernel to the manufacture of paper, as
herein-before described.
In witness whereof, I, the said Henry Diaper, have hereunto set my
hand and seal, this Eighteenth day of May, in the year of our Lord
One thousand eight hundred and fifty-five.
Witness,
CHARLES COWPER,
20, Southampton Buildings,
Chancery Lane.
