A MODE OF TREATING AND PREPARING SEA WEEDS OR MARINE PLANTS FOR MANURE
Year: 1856

page_text: LETTERS PATENT to Charles Durand Gardissal, of 10, Bedford Street,
Strand, London, and of 29, Boulevart St. Martin, Paris, Patent Agent,
for the Invention of "A MODE OF TREATING AND PREPARING SEA WEEDS
OR MARINE PLANTS FOR MANURE."-A communication
Sealed the 20th February 1857, and dated the 28th August 1856.
PROVISIONAL SPECIFICATION left by the said Charles Durand Gardissal
at the Office of the Commissioners of Patents, with his Petition, on
the 28th August 1856.
I, CHARLES DURAND GARDISSAL, of 10, Bedford Street, Strand, London,
and of 29, Boulevart St. Martin, Paris, Patent Agent, do hereby declare
the nature of the said Invention for "A MODE OF TREATING AND PREPARING
SEA WEEDS OR MARINE PLANTS FOR MANURE," (a communication,) to be as
follows:-
This Invention relates to a certain treatment of sea weeds, or marine plants
of any kind, whereby those matters are rendered applicable as a manure, and
reduced to a condition which renders them readily capable of being transported
from the place where they are collected to the locality in which they are to be
applied as manure, or for the purpose of obtaining salts therefrom to be used
as a manure. The weeds are collected and subjected to a great pressure,
whereby their bulk is reduced and rendered in the form of balls or cakes.
This process of compression may either take place while the plants are in a wet

page_text: mucilaginous state, or after having been previously dried, when the mucilage
and chloride of sodium is left on the plant. In either case the compression
of these matters may be effected in the cold state, or it may be previously
heated and softened by a jet of steam, hot water, or other suitable heating
medium.
Instead of proceeding as above, the sea weeds may be collected, and while
in a wet state, or after having been dried, are reduced by cutting or crushing
machinery of a suitable kind. The pulp produced is then condensed by
pressure, and reduced to the form of cakes, in which condition it is easily
capable of transport. The pressure may be applied to the pulp in a cold state,
or after it has been heated or softened by steam or hot water.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Durand Gardissal in the Great Seal Patent Office
on the 26th February 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
DURAND GARDISSAL, of No. 10, Bedford Street, Strand, London, and of
29, Boulevart St. Martin, Paris, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of August, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Durand Gardissal, Her special licence that I, the said Charles
Durand Gardissal, my executors, administrators, and assigns, or such others
as I, the said Charles Durand Gardissal, 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 Inven-
tion for "A MODE OF TREATING AND PREPARING SEA WEEDS OR MARINE PLANTS FOR
MANURE," a communication, upon the condition (amongst others) that I, the
said Charles Durand Gardissal, my executors or administrators, by an
instrument in writing under my, 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.

page_text: NOW KNOW YE, that I, the said Charles Durand Gardissal, 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 (that is to say):-
This Invention relates to the treatment of sea weeds, or marine plants of
any kind, whereby those matters are rendered applicable as a manure, and
reduced to a condition which renders them readily capable of being transported
from the place where they are collected to the locality in which they are to be
applied as manure, or for the purpose of obtaining salts therefrom to be used
as a manure. The weeds are collected and subjected to a great pressure,
whereby their bulk is reduced and rendered in the form of balls or cakes.
This process of compression may either take place while the plants are in a
wet mucilaginous state, or after having been previously dried, the mucilage
and chloride of sodium being left on the plants.
In either case the compression of these matters may be effected in the cold
state, or it may be previously heated and softened by a jet of steam, hot water,
or other suitable heating medium.
Instead of proceeding as above, the sea weeds may be collected, and while
in a wet state, or after having being dried, are reduced by cutting or crushing
machinery of a suitable kind. The pulp produced is then condensed by pressure,
and reduced to the form of cakes, in which condition it is easily capable of
transport. The pressure may be applied to the pulp in a cold state, or after
it has been heated or softened by heat or hot water.
Having described the nature of my Invention, and the manner in which it
may be formed, I desire it to be understood that what I claim as my Invention,
protected by the herein-before in part recited Letters Patent, is treating and
preparing, as herein-before described, sea weeds or marine plants to be used as
manure.
In witness whereof, I, the said Charles Durand Gardissal, have here-
unto set my hand and seal, this Twenty-first day of February, in the
year of our Lord One thousand eight hundred and fifty-seven.
C. D. GARDISSAL. (L.B.)
