page_text: LETTERS PATENT to Edward Charles Hamilton, of Camp House,
Colchester, in the County of Essex, for the Invention of "In-
PROVEMENTS IN THE MANUFACTURE OF MANURE."
PROVEMENTS IN THE MANUFACTURE OF Manure.”
Sealed the 20th October 1873, and dated the 14th June 1873.
PROVISIONAL SPECIFICATION left by the said Edward Charles
Hamilton at the Office of the Commissioners of Patents, with his
Petition, on the 14th June 1873.
I, EDWARD CHARLES HAMILTON, of Camp House, Colchester, in the
County of Essex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF MANURE," to be as follows:-
The object of this Invention is to manufacture manure in a dry
powdered condition from fish, more especially from the Uraster Rubens,
commonly called a five finger, or from star fish. The fish are first passed
through a mincing machine, and thus reduced to a pulp, after which the
pulped matter is passed through a drying machine the temperature in
which is so regulated as not to damage or interfere with the ammoniacal

page_text: properties of the fish; a temperature of about 130° will be found suit-
able. The pulp after being thus dried in the drying machine is passed
into a mill, in which it is reduced to the state of powder, and in this
condition it is used as a manure.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Charles Hamilton in the Great Seal Patent
Office on the 13th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
CHARLES HAMILTON, of Camp House, Colchester, in the County of Essex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of June, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Charles Hamilton, Her special
license that I, the said Edward Charles Hamilton, my executors, adminis-
trators, and assigns, or such others as I, the said Edward Charles
Hamilton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 In-
vention for "IMPROVEMENTS IN THE MANUFACTURE OF MANURE," upon the con-
dition (amongst others) that I, the said Edward Charles Hamilton, 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.
NOW KNOW YE, that I, the said Edward Charles Hamilton, 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 :-

page_text: The object of this Invention is to manufacture manure in a dry
powdered condition from fish, more especially fron the Uraster Rubens,
commonly called a five finger, or from star fish. The fish are first
passed through a mincing machine and thus reduced to a pulp, after
which the pulped matter is passed through a drying machine, the tem-
perature in which is so regulated as not to damage or interfere with the
ammonical properties of the fish; a temperature of about 130° will be
found suitable. The pulp after being thus dried in the drying machine
is passed into a mill in which it is reduced to the state of powder, and in
this condition it is used as a manure.
In practically carrying out my Invention I prefer to employ for
reducing the fish to pulp mincing machines constructed on the principle
of the well-known Nye's mincing machine, and for drying the pulped
matter I prefer to employ drying machines constructed on the principle
of Milburn's drying machine, which is also well known.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I claim the
manufacture of manure in a dry powdered condition from fish, sub-
stantially in the manner herein described.
In witness whereof, I, the said Edward Charles Hamilton, have
hereunto set my hand and seal, this Twelfth day of December,
in the year of our Lord One thousand eight hundred and seventy-
three.
