IMPROVEMENTS IN DEODORIZING BLOOD TO ENABLE IT TO BE USED FOR MANURING AND OTHER PURPOSES
Year: 1875

page_text: LETTERS PATENT to John Smith, of the Cattle Market, London, in
the County of Middlesex, Chemical Manufacturer, for the Inven-
tion of "IMPROVEMENTS IN DEODORIZING BLOOD TO ENABLE IT TO BE USED
FOR MANURING AND OTHER PURPOSES."
:
PROVISIONAL SPECIFICATION left by the said John Smith at the
Office of the Commissioners of Patents, with his Petition, on the
20th May 1875. .
I, JOHN SMITH, of the Cattle Market, London, in the County of Mid-
dlesex, Chemical Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN DEODORIZING BLOOD TO ENABLE IT TO BE
USED FOR MANURING AND OTHER PURPOSES," to be as follows:-.
The object of my Invention is so to treat blood as to render it
inoffensive and free from all properties injurious from a sanitary point
of view.
My Invention consists in treating natural and refuse blood with
from 25 to 50 per cent. of phosphate of lime or ground coprolites;

page_text: •
these I well mix together; I then add to this mixture about 5`per cent.
more or less of calcic oxide, and I then again stir the mixture; I then
add about ten per cent. as near as possible of sulphuric acid, preferably
of a density of 17° Twaddle or thereabouts. I then woll agitate the mix-
ture, and the process is complete. Or all the above constituents may
be added to the blood at once, and the mixture then agitated, but I
prefer the successive additions and stirrings. The blood. thus treated
will be found to be perfectly deodorized and inoffensive, and may be at
once applied for use as manure, for which it is very valuable, or for
sugar refining instead of the animal black generally used, or for other
purposes.
Instead of the final addition of 10 per cent. of sulphuric acid to the
mixture, I prefer to add 25 per cent., more or less, of a substance
known as ammonia lignine, that is to say, sawdust treated with
the liquor left from the purification of coal gas, the ammonia lignine
having been previously saturated with 8 per cent. of sulphuric acid.
The use of ammonia lignine is to be preferred to that of sulphuric
acid when it is obtainable, in consequence of its conveying a certain
proportion of ammonia to the blood, and on account of its property of
absorbing the water suspended therein.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Smith in the Great Seal Patent Office on
the 19th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SMITH, of the Cattle Market, London, in the County of Middlesex, 2
Chemical Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of May, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and 8
grant unto me, the said John Smith, Her special license, that I, the
said John Smith, my executors, administrators, and assigns, or such
others as I, the said John Smith, my executors, administrators, and
assigns, should at any time agree with, and no others, from time

page_text: 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 DEODORIZING BLOOD
* TO ENABLE IT TO BE USED FOR MANURING AND OTHER PURPOSES," upon the con-
dition (amongst others) that I, the said John Smith, 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 John Smith, 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 :-
The object of my Invention is so to treat blood as to render it
inoffensive, and free from all properties injurious from a sanitary point
of view.
My Invention consists in treating natural and refuse blood with
from 25 to 50 per cent. of phosphate of limo or ground coprolites.
These I well mix together; I then add to this mixture about 5 per cent.
more or less of calcic oxide, and I then again stir the mixture; I then
add about 10 per cent. as near as possible of sulphuric acid, preferably
of a density of 17° Twaddle or thereabouts; I then well agitate the mix-
ture, and the process is complete. Or all the above constituents may be
added to the blood at once, and the mixture then agitated; but I
prefer the successive additions and stirrings. The blood thus treated
will be found to be perfectly deodorized and inoffensive, and may be at
once applied for use as manure, for which it is very valuable, or for
sugar refining instead of the animal black generally used, or for other
purposes.
'
Instead of the final addition of 10 per cent. of sulphuric acid to the
mixture I prefer to add 25 per cent. more or less of a substance known
as ammonia lignine, that is to say, sawdust treated with the liquor left
from the purification of coal gas, the ammonia lignine having been
previously saturated with 8 per cent, of sulphuric acid,

page_text: The use of ammonia lignine is to be preferred to that of sulphuric
acid when it is obtainable, in consequence of its conveying a certain
proportion of ammonia, to the blood, and on account of its property of
absorbing the water suspended therein.
Having now set forth the nature of my Invention, and the manner of
carrying it into practice,―
Firstly. I claim as my improvements the treatment of blood in the
manner and for the purpose described.
Secondly. I claim the employment of the ingredients herein-before
referred to, to deodorize blood and render it inoffensive without destroying
its property as a fertilizing agent, as set forth.
In witness whereof, I, the said John Smith, have hereunto set
my hand and seal, this Eighteenth day of November, One
thousand eight hundred and seventy-five.
