IMPROVE- MENTS IN THE MANUFACTURE OF MANURES
Year: 1855

page_text: LETTERS PATENT to Manning Prentice, of Stowmarket, and Thomas
Richardson, of Newcastle-upon-Tyne, for the Invention of "IMPROVE-
MENTS IN THE MANUFACTURE OF MANURES."
Sealed the 12th June 1855, and dated the 30th March 1855.
PROVISIONAL SPECIFICATION left by the said Manning Prentice and
Thomas Richardson at the Office of the Commissioners of Patents, with
their Petition, on the 80th March 1855.
We, MANNING PRENTICE, of Stowmarket, and THOMAS RICHARDSON, of
5 Newcastle-upon-Tyne, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF MANURES" to be as follows:-
Our process consists in dissolving phosphates of lime or of magnesia in
muriatic acid, to which we add gas water or other compound or source of
ammonia, such as Peruvian guano, and mixing with such matters muriate of
potash or soda; or we add sulphate of potash or soda to the first-named solution
of earthy phosphates in muriatic acid, and remove the sulphate of lime which
precipitates, and mix gas water or other ammoniacal compound with the
supernatant liquid. These liquid manures are capable of conveyance in casks,
and require to be diluted for use.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Manning Prentice and Thomas Richardson in the Great Seal
Patent Office on the 27th August 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MANNING
PRENTICE, of Stowmarket, and THOMAS RICHARDSON, of Newcastle-upon-Tyne,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of March, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Manning Prentice and Thomas Richardson, Her special licence that we, the
said Manning Prentice and Thomas Richardson, our executors, administrators,
and assigns, or such others as we, the said Manning Prentice and Thomas
Richardson, our 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 MANURES," upon the condition (amongst others) that we,
the said Manning Prentice and Thomas Richardson, by an instrument in
writing under our hands and seals, or under the hand and seal of one of us,
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 we, the said Manning Prentice and Thomas
Richardson, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say:-
Our process consists in dissolving phosphates of lime or of magnesia in
muriatic acid, to which we add gas water or other compound or source of
ammonia, such as Peruvian guano, and mixing with such matters muriate of
potash or soda; or we add sulphate of potash or soda to the first-named
solution of earthy phosphates in muriatic acid, and remove the sulphate of
lime which precipitates, and mix gas water or other ainmoniacal compound
with the supernatant liquid. These liquid manures are capable of conveyance
ia casks, and require to be diluted for use.

page_text: Having thus stated the nature of our Invention, we will proceed to describe
the manner of performing the same.
We ascertain as usual by analysis the quantity of lime present in the
phosphatic substance to be used, and mix with it as much muriatic acid as
will combine with the whole of the lime. This mixture is made in a wooden,
leaden, or stone vessel, and assisted by heat to facilitate the operation, although
this is not absolutely necessary.
We mix with this solution about equal
quantities of gas water, or an equivalent quantity of Peruvian or other guano,
or ammoniacal compound, free or nearly free from sulphuric acid or sulphate.
We then dissolve as much muriate of potash or soda as will amount to about
ten per cent. on the quantity of solid matters in solution.
This liquid manure may then be run into carboys or casks, and when largely
diluted with water can be applied directly to the land, being especially adapted
to grass or meadows.
Instead of employing muriate of potash or soda, we mix an equivalent
quantity of sulphates of these alkalies, and we allow the sulphate of lime
which is precipitated to subside, while we run off the supernatant liquid with
which we proceed as already explained.
In witness whereof, we, the said Manning Prentice and Thomas,
Richardson, have hereunto set our hands and seals, this Seventeenth
day of August, in the year of our Lord One thousand eight hundred
and fifty-five.
Witness,
S. CARPMAEL.
