Year: 1874

page_text: LETTERS PATENT to Edward Heinson Huch, of Brunswick, in the
Empire of Germany, for the Invention of "IMPROVEMENTS IN PRE-
SERVING BLOOD FOR USE AS FOOD."
Scaled the 10th November 1874, and dated the 15th May 1874.
PROVISIONAL SPECIFICATION left by the said Edward Heinson Huch
at the Office of the Commissioners of Patents, with his Petition, on
the 15th May 1874.
I, EDWARD HEINSON HUCH, of Brunswick, in the Empire of Germany,
do hereby declare the nature of the said Invention for “IMPROVEMENTS
IN PRESERVING BLOOD FOR USE AS FOOD," to be as follows:
This Invention has for its object improvements in preserving blood for
use as food. For this purpose I treat blood with lime in a state of
powder or mixed with water and allow it to settle. I draw off the clear
liquid and mix with it farinaceous or other matters and dry it. In this
way I obtain a material which is suitable for food. Or in some cases I
évaporate the clear liquid without admixture with farinaceous or other
matters.

filed by the said Edward Heinson Hucli in the Great Seal Patent
Office on the 13th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
HEINSON HUCH, of Brunswick, in the Empire of Germany, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of May, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Edward Heinson Huch, Her
special license that I, the said Edward Heinson Huch, my executors,
administrators, and assigns, or such others as I, the said Edward Heinson
Huch, my 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,
üse, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN PRESERVING BLOOD FOR USE AS FOOD," upon the con-
dition (amongst others) that I, the said Edward Heinson Huch, 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 Heinson Huch, 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 :-
This Invention has for its object improvements in preserving blood.
My process is such that the preserved blood is fit for food, but as the
treatment is inexpensive the preserved blood may be used for other
purposes, for example, as manure. I take the blood as fresh as possible,
for it begins to putrify almost directly it comes in contact with the air.

page_text: I put into a vessel large enough to take the blood of one ox from 7 to
15 ounces of fresh quicklime in powder, which is enough for the blood
of one ox (say 36 lbs. of blood), or I put the lime into the vessel after
the fresh blood having run into it, or at the same time the blood is
running into it I mix the lime with the blood by stirring it for 2 to 5
miñutes till the blood changes somewhat in color and is becoming darker.
Then I let it settle for 5 to 10 minutes. The blood becomes gelatinous
and I take it out of the vessel and crush it to small pieces and dry it in
the sun or air or in a hot room, or I mix it with any substance good for
food and dry it. The substances can be very different. I generally take
onc part of bran and 3 parts of blood, that is to say to the blood of an
ox I add from 8 to 10 lbs. of bran or ground oil cake; but less or more
blood may be taken. Other substances may be added, and especially it
is desirable to add a small quantity of bone ash. Then I dry the mixture
in the sun or air or in a hot room or drying chamber. Thus I preserve
blood from putrification by mixing it with a small quantity of ground
or powdered quicklime, which settles after having absorbed a quantity
of the moisture of the blood, so that hardly any of the lime remains in
the blood, and the blood (either alone or mixed with other substances)
becomes a good and healthy food for horses, cattle, poultry, &c. It is
also an excellent manure, and after it has been dried by sun, air, or in a
hot room or drying chamber and ground it can be preserved in good
state for a long time. It will be even a good nutriment for mankind.
What I claim is the preparation of blood by treating it with powdered
quicklime, substantially in the manner described.
In witness whereof, I, the said Edward Heinson Huch, have herc-
unto set my hand and seal, this First day of November, in the
year of our Lord One thousand eight hundred and seventy-
four.
