IMPROVEMENTS IN THE UTILI- ZATION AND AERATION OF PREPARED AND PRESERVED MILK
Year: 1876

page_text: LETTERS PATENT to John Hooker, of 104, Upper Thames Street, in the City
of London, Gentleman, for the Invention of "IMPROVEMENTS IN THE UTILI-
ZATION AND AERATION OF PREPARED AND PRESERVED MILK."
Sealed the 7th October 1876, and dated the 15th April 1870.
PROVISIONAL SPECIFICATION left by the said John Hooker at the Office
of the Commissioners of Patents on the 15th April 1876.
JOHN HOOKER, of 104, Upper Thames Street, in the City of London, Gentleman.
"IMPROVEMENTS IN THE UTILIZATION AND AERATION OF PREPARED AND PRESERVED
MILK."
I take any suitable vessel in which I place either milk as drawn from the
cow or other milk, and either raw or in a preserved or condensed state, and
with or without sugar or other preservative ingredient, and I fill up such vessel'
in the usual method adopted by manufacturers of soda and alkaline waters,
with a suitable carbonic acid apparatus filled with water, charged with carbonic
acid or other gas, and containing a certain proportion of bicarbonate of soda or
other alkaline salts. The raw milk and the aerated alkaline solution are mixed
in about equal proportions, but when condensed or preserved milk, whether with
or without sugar, is used a larger proportion of water will have to be added to
replace the water displaced by the process of condensation or preservation from the
normal bulk of the raw milk, and consequently the alkaline solution used with
such condensed or preserved milk will contain a less relative proportion of bi-
carbonate of soda or other alkaline salts than that used with the raw milk.
will be so arranged that the relative proportions of alkaline salts will be the same
in all the bottles of the mixture when so prepared.
This
I do not claim as new the mere mixture of milk with soda water, or the mero
impregnation of milk with carbonic acid gas, but I do claim as an improvement the
mixture of milk with water impregnated with carbonic acid or other gas and soda
or other alkaline salts, and the sale thereof in bottles similar to the bottles used
for the ordinary soda or other alkaline waters.

JOHN HOOKER, of 104, Upper Thames Street, in the City of London, Gentleman.
IMPROVEMENTS IN THE UTILIZATION AND AERATION OF PREPARED AND PRESERVED
MILK."
I take any suitable vessel in which I place either milk as drawn from the cow,
or skimmed or other milk, and either raw or in a preserved or condensed state,
and with or without sugar or other preservative ingredient, and I fill up such
vessel in the usual method adopted by manufacturers of soda and other alkaline
waters, with a suitable or carbonic acid apparatus filled with water charged with
carbonic acid or other gas or gasses, or with ordinary air, and containing a certain
proportion of bicarbonate of soda, potash, or other alkaline salts equal to ten or
fifteen grains of the salt in each bottle. The raw milk and the aerated alkaline
solution are mixed in about equal proportions, but when condensed or preserved
milk, whether with or without sugar, is used a larger proportion of water will
have to be added to replace the water displaced by the process of condensation
or preservation from the normal bulk of the raw milk, and consequently the alkaline
solution used with such condensed or preserved milk will contain a less relative
proportion of bicarbonate of soda, potash, or other alkaline salts than that used with
the raw milk. This will be so arranged that the relative proportions of alkaline
salts will be the same, say from ten to fifteen grains, in all the bottles of the
mixture when so prepared.
I do not claim as new the mere mixture of milk with soda water, or the mere
impregnation of milk with carbonic acid gas, but I do claim as an improvement the
mixture of milk with water impregnated with carbonic acid or other gas or gases,
and soda, potash, or other alkaline salts, and the sale thereof in bottles similar
to the bottles used for the ordinary soda or other alkaline or areated waters.
In witness whereof, I, the John Hooker, have hereunto set my hand and
seal, this Fourteenth day of October, One thousand eight hundred and
seventy-six.
