IMPROVEMENTS IN THE PROCESS OF PRESERVING, MILK
Year: 1857

page_text: LETTERS PATENT to Johannes Neuenschwander, of Albion Wharf, Ken-
sington Basin, Kensington, for the Invention of "IMPROVEMENTS IN THE
PROCESS OF PRESERVING, MILK."
Sealed the 8th May 1857, and dated the 10th March 1857.
PROVISIONAL SPECIFICATION left by the said Johannes Neuenschwander
at the Office of the Commissioners of Patents, with his Petition, on the
10th March 1857.
I, JOHANNES NEUENSCHWANDER, of Albion Wharf, Kensington Basin, Ken-
sington, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE PROCESS OF PRESERVING MILK," to be as follows:-
One of my improvements consists in putting the milk immediately after it
has been obtained and whilst quite new into a suitable vessel, in which it is
parboiled and then agitated during about ten minutes, whereupon a decoction,
consisting of milk mixed with horseraddish, is added to it, in the proportion of
one quart of the concoction to about ten quarts of the milk. In preparing
this concoction, I take about lb. of grated horseraddish, to which I add
three quarts of milk; this mixture is then parboiled and passed through linen
or other sieve of fine texture. When the concoction has been added to the
milk, the boiling process is suspended, and the milk drawn off into bottles at
as high a temperature as the bottles will bear. The bottles are then imme-
diately corked, and the process is completed.

page_text: My other improvement consists in bottling the milk immediately after it
has been obtained, and then placing the bottles into a vessel containing cold
water, where they are boiled during about an hour.. The process of boiling is
then suspended, and the bottles allowed to remain in the water for about a
quarter of an hour, whereupon the preserving process is completed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Johannes Neuenschwander in the Great Seal Patent Office
on the 10th September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHANNES
NEUENSCHWANDER, of Albion Wharf, Kensington Basin, Kensington, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria," by Her Letters
Patent, bearing date the Tenth day of March, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Johannes Neuenschwander, Her special licence that I, the said Johannes
Neuenschwander, my executors, administrators, and assigns, or such others
as I, the said Johannes Neuenschwander, 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, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN THE PROCESS OF PRESERVING MILK," upon the con-
dition (amongst others) that I, the said Johannes Neuenschwander, my
executors or administrators, by an instrument in writing under 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 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 Johannes Neuenschwander, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement (that is to say):-
One of my improvements consists in putting the milk immediately after it
has been obtained and whilst quite new into a suitable vessel, in which it is

page_text: parboiled and then agitated during about ten minutes, whereupon a decoction,
consisting of milk mixed with horseraddish, is added to it, in the proportion of
one quart of the concoction to about ten quarts of the milk. In preparing
this concoction, I take about lb. of grated horseraddish, to which I add
three quarts of milk; this mixture is then parboiled and passed through linen
or other sieve of fine texture. When the concoction has been added to the
milk, the boiling process is suspended, and the milk drawn off into bottles at
as high a temperature as the bottles will bear. The bottles are then imme-
diately corked, and the process is completed.
My other improvement consists in bottling the milk immediately after it
has been obtained, and then placing the bottles into a vessel containing cold
water, where they are boiled during about an hour. The process of boiling is
then suspended, and the bottles allowed to remain in the water for about a
quarter of an hour, whereupon the preserving process is completed.
Having now described the nature of my Invention, and the mode of carrying
the same into effect, I wish it to be understood that I claim the two processes
of preserving milk as above described.
In witness whereof, I, the said Johannes Neuenschwander, have hereunto
set my hand and seal, this Tenth day of September, in the year of our
Lord One thousand eight hundred and fifty-seven.
J. NEUENSCHWANDER. (L.S.)
