Improvements in the Manufacture of Manures and Fertilizers.
I MARGARETHA CATHARINA GINSTER Manure Manufacturer, Germania Cottage
Goosemore Lane Erdington Birminghain in the County of Warwick do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to produce a fertilizer from blood or blood and fish
combined for top dressing and for all kinds of vegetation, more particular for fruit
trees, vines, and flowers.
I am aware that fertilizers have been made from blood and other organic matters
but my invention relates to a process of producing a much richer fertilizer, by a
simple and much cheaper process than hitherto.
I will now declare the manner of carrying out my invention into effect.
Blood manure can be made without machinery by using chemicals my process
consists in passing the blood through a screen "which must be fixed over a tank.".
into a tank while in the tank add brown oil of vitrol in the proportion of 20 to 30 lbs.
to the ton of blood, "the vitrol should be from 155 to 160 strong" constantly
stirring the mixture for about 15 minutes with a wooden rake or any suitable
instrument, then let the mixture stand from 10 to 12 hours to allow them to blend
well together, then take the mixture out of the tank, put it into a press to drain off
the liquid, this liquid should be mixed with some dry substance such as bone dust, or
wool dust, to preserve it; the solid matter should be taken from the press broken up
with any suitable instrument, it must now be dried in the sun or in a kiln with a
temperature not exceeding 100° Far. if the blood is from horned cattle the mixture
will contain about 14% of nitrogen which is equivalent to 17% of amonia.
To manufacture blood manure without chemicals I proceed in the following manner,
"first it is most essential that the blood should be fresh" I pass the blood through the
screen as in the former case, then put it into a boiler or cauldron, which must be
jacketed to prevent the blood from coming in contact with dry heat, boil for about
of an hour, it is now ready for cooling which can be done by spreading upon a brick
or stone floor when cool put it into a press and drain off all the liquid and dry the
solid matter as in the previous process this will contain 11% of nitrogen being
equivalent to 13% of amonia.
The process of treating the fish is in the following manner, chop the fish very fine
in a suitable chopper it then should be put into a tank and brown oil of vitrol added
in the proportion of 35 to 40 lbs. to the ton of fish constantly stirring for about
15 minutes, it should now stand from 6 to 8 hours after this drain off the liquid, this
liquid should be preserved as in the case of the blood manure; the solid matter must
now be dried in the sun or kiln with not more than 80° Far. this is a very rich
fertilizer, but if mixed with the blood manure in proper proportions suitable to the
requirements a fertilizer will be produced yealding a very high percentage of
phosphate and amonia, the highest that can be produced from organic matter if
my process of manufacture be strictly carried out.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Manures and Fertilizers.
MARGARETHA CATHARINA GINSTER Germania Cottage Erdington in the County of
Warwick do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly aescribed and ascertained in and by the
following statement :-
The object of my invention is to produce a rich fertilizer possesing a high

page_text: percentage of ammonia and phosphate from blood or blood & fish combined or other
organic matter for top & bottom dressing and all kinds of vegetation the blood
manure more particularly for fruit trees vines etc.
I am aware that fertilizers have been made from blood and other organic matter;
but my invention deals with and relate to a process of producing a much richer
fertilizer than hitherto claimed, also by a much cheaper, simpler and shorter method
than hitherto carried out by other manufacturers.
I will now declare the manner of carrying out my invention, and bringing the same
into effect. Blood can be manufactured into manure with or without machinery, what
I more particularly deal with is the manufacture of manure without machinery, by
using chemicals which is as follows.
My process consists in collecting the blood in suitable vessels then passing it
through a screen which must be fixed over a tank of suitable dimensions. While in
the tank add brown oil of vitriol in the proportion of 35 to 40 pounds to the ton of
blood, "the vitriol should be about 155 strong constantly stirring the mixture
دو
from 10 to 15 minutes with a wooden rake or other suitable instrument.
It is now necessary to let the mixture stand for 10 or 12 hours to allow them to
blend well together and become one coagulated mass. The mixture can now be taken
out of the tank put into a press to drain off, the liquid; this liquid should be mixed
with some dry substance such as bone dust, or wool dust to preserve it; this in itself
will make a good manure. The solid matter should now be taken from the press
broken up with any suitable instrument and exposed to the sun or dried in a kiln with
à temperature not exceeding 100° Far.
If the blood treated as here before described is from horned cattle the manure will
contain about 14% of nitrogen which is equivalent to 17% of ammonia.
If the blood used is mixed and not entirely from horned cattle the percentage of
ammonia will be somewhat less.
The manufacture of blood manure without chemicals as referred to in my pro-
visional specification dated the 13 day of January 1890 1 have abandoned.
The process of treating the fish is in the following manner, I chop the fish very fine
and put it in a tank adding brown oil of vitrol in the proportion of 35 to 40 pounds
to the ton of fish constantly stirring the mixture for about 15 minutes. It should
now stand from 6 to 8 hours. After this drain off the liquid, and treat it in the same
manner as the blood liquid.
The solid matter should now be dried in the sun or kiln temperature not
exceeding 80° Far. This produces a very rich fertilizer with a high percentage of
phosphate and ammonia but is variable according to the nature of the material
delt with.
If the blood & fish manure is mixed together in suitable proportions such as may
be required for the land it is intended for, or the various kinds of crops and vegetation,
it will be found to be the best and richest fertilizer that can be manufactured, suitable
for all seasons and lasting the longest in the land owing to the homogenity of the
mixture if my process of manufacture be strictly carried out as herebefore described.
Having now fully described my said invention and the manner of performing the
same I set forth my claim.
1st. Without the aid of machinery I produce from blood fish or other organic
matter a fertilizer richer in chemical properties than has hitherto been produced.
2nd. By my process I produce this fertilizer and fix the chemical properties without
the introduction of any foreign matter to increase bulk.
3rd. I convert the raw material into manure in less than 24 hours, thereby avoiding
any unpleasantness caused by decomposition, also producing a fertilizer at a very
cheap rate.
