Year: 1855

page_text: LETTERS PATENT to Louis Antoine Ritterbandt, of Warwick Street,
Regent Street, M.D., and Joseph Bower, of Hunslet, near Leeds,
Manufacturing Cheniist, for the Invention of "AN IMPROVEMENT IN THE
MANUFACTURE OF MANURE."
Sealed the 30th October 1855, and dated the 24th July 1855.
PROVISIONAL SPECIFICATION left by the said Louis Antoine Ritterbandt
and Joseph Bower at the Office of the Commissioners of Patents, with
their Petition, on the 24th July 1855.
We, LOUIS ANTOINE RITTERBANDT, of Warwick Street, Regent Street, M.D.,
and JOSEPH BOWER, of Hunslet, near Leeds, Manufacturing Chemist, do hereby
declare the nature of the Invention for "AN IMPROVEMENT IN THE MANUFACTURE
OF MANURE" to be as follows:-
The nature of our Invention consists in manufacturing a useful and com-

grind clinkers into a powder sufficiently fine to pass through a sieve of about
625 holes to the square inch. We then add thereto sulphuric, muriatic, or
other acid having the property of developing phosphoric acid, and the result is
suitable for the purposes of manure.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LOUIS
ANTOINE RITTERBANDT, of Warwick Street, Regent Street, M.D., and JOSEPH
BOWER, of Hunslet, near Leeds, Manufacturing Chemist, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of July, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her reign.
did, for Herself, Her heirs and successors, give and grant unto us, the said
Louis Antoine Ritterbandt and Joseph Bower, Her special licence that we, the
said Louis Antoine Ritterbandt and Joseph Bower, our executors, adminis-
trators, and assigns, or such others as we, the said Louis Antoine Ritterbandt
and Joseph Bower, 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 "AN IMPROVEMENT
IN THE MANUFACTURE OF MANURE," upon the condition (amongst others) that
we, the said Louis Antoine Ritterbandt and Joseph Bower, 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 I, the said Louis Antoine Ritterbandt, on behalf
of myself and the said Joseph Bower, 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:
Our Invention consists of manufacturing manure by employing clinkers in
combination with acids, such as are employed in developing phosphoric acid
when acting on phosphates.
In carrying out our Invention, we cause the clinkers obtained from furnaces
where coal or coke is consumed to be broken down and reduced to powder,
such as will pass through a sieve of about six hundred and twenty-five holes
to the square inch, and we then combine with such powder of clinkers sulphuric

page_text: or other acid, such as are known to develope phosphoric acid when acting on
phosphates. It will be found that by thus combining clinkers with and causing
them to be acted on by an acid or acids, the compound produced will be very
fertilizing, and may be used alone or in combination with other manures; and
we can, for instance, use the acid or acids above mentioned after having employed
it or them to act on old leather or other animal matter to dissolve the sanie,
by which a compound manure, composed of clinkers and animal matter with
au acid or acids, will be obtained. And in like manner the acid or acids may
be first used to act on phosphates and then be combined with clinkers, but we
make no claim to the acting by acids on animal matter or on phosphates, our
Invention simply consisting of combining acid with clinkers for the manufacture
In combining the powder of clinkers with acid, we prefer to use
at the rate of one hundred and twelve pounds of clinkers with fifty-six pounds
of sulphuric acid, specific gravity 1.400; but this may be varied, and other acid
may be used in place of or in combination with sulphuric acid. We simply
mix the acid and the powder of clinkers together as intimately as may be, and
then the compound is complete and ready for the purposes of manure. What
we claim is, the combining clinkers with acids, such as are herein mentioned,
in order to manufacture manure.
In witness whereof, I, the said Louis Antoine Ritterbandt, have hereunto
set my hand and seal, this Twelfth day of January, in the year of our
Lord One thousand eight hundred and fifty-six.
Witness,
S. CARPMAEL.
