page_text: LETTERS PATENT to Aubrey Nelson, of Margate, in the County of Kent, for
the Invention of "AN IMPROVED PREPARATION OR BEVERAGE HAVING
NOURISHING AND MEDICINAL QUALITIES.”
Sealed the 18th February 1879, and dated the 6th November 1878.
PROVISIONAL SPECIFICATION left by the said Aubrey Nelson at the

RATION OR BEVERAGE HAVING NOURISHING AND MEDICINAL QUALITIES."
AN IMPROVED PREPA-
My Invention has for its object an improved preparation or beverage possessing
nourishing and medicinal properties, and which may also be still further medicated
by the addition of a suitable medicament such as lithia, soda, potass, magnesia,
seltza, quinine, and others suited for the cure or alleviation of different ailments or
diseases.
My Invention consists mainly in charging milk with carbonic acid gas at a high
tension in the same way that aerated waters are so charged, and in further medi-
cating the above beverage, if desired, by the addition of a suitable drug, as above
mentioned. Owing to the body or consistency of the milk the carbonic acid gas
does not escape so quickly as from ordinary aerated water when poured out, and a
greater proportion is consequently taken into the stomach, so that in addition to
the nourishing properties of the milk a more beneficial effect is produced than by an
equal quantity of ordinary aerated water. Moreover, the presence of the carbonic
acid gas will, so long as the bottle is unopened, preserve the milk in its natural
condition of freshness for an indefinite period.
In carrying out my Invention I fill a bottle about one third with pure milk, and
add a proper proportion of any medicine desired, which must not however be of
such a nature as to cause the milk to curdle. I then by means of an ordinary soda

page_text: water machine fill up the bottle with pure spring, filtered, or distilled water charged
with carbonic acid gas at a pressure of, say, from 120 lbs. to 150 lbs. to the square
inch, and cork the bottle in the usual way. The milk must be direct from the cow,
and put through this process before cream is allowed to form.

AUBREY NELSON, of Margate, in the County of Kent. "AN IMPROVED PREPA-
RATION OR BEVERAGE HAVING NOURISHING AND MEDICINAL QUALITIES."
My Invention has for its object the manufacture of an improved preparation or
beverage possessing nourishing and medicinal properties, and which may in some
cases be still further medicated by the addition of lithia, soda, potass, inagnesia,
quinine, iron or other medicament suited for the cure or alleviation of different
ailments or diseases.
My Invention consists mainly in charging milk with carbonic acid gas at a high
tension in the same way that æerated waters are charged, and in medicating the
above beverage, if desired, by the addition of a drug as above mentioned, which
must not however be such as to curdle the milk. Owing to the body or consistency
of the milk the carbonic acid gas does not escape so quickly as from ordinary ærated
water when the beverage is poured out, and a greater proportion of the gas is con-
sequently taken into the stomach, so that in addition to the nourishing properties
of the milk a more beneficial effect is produced than by an equal quantity of
ordinary æerated water. Moreover, the presence of the carbonic acid gas will, so
long as the_bottle is unopened, preserve the milk in its natural condition of
freshness.
In carrying out my Invention I place the pure milk in an æerating cylinder; I
then, by means of a gas pump, charge it with carbonic acid gas to the required
pressure, after which I bottle the milk so charged in the usual way.
The machine I use is a simple ærating machine such as used for ærating wines,
cyder, or any liquors liable to froth up. When the beverage is to be medicated or
flavored with syrup or essences, these would of course be added to the milk in
proper proportion before it is charged with the gas; and when the beverage
(whether medicated or flavored as above mentioned or not) is required to keep for
a long time the new milk is first heated by steam to about 200° Fah., and allowed
to cool before the medicine, syrup, or essence (if any) is mixed with it, after which
it is charged with gas, bottled, corked, and sealed.
The proportion of the various medicaments or flavorings varies widely according
to taste and requirements, so that it is impossible to specify them here. When the
beverage is not required to be made of pure milk the bottles are about half filled
with milk, and then filled up by means of an ordinary soda water machine with
spring, filtered, or mineral water charged with carbonic acid gas at a high pressure

page_text: (160 lbs.), and corked in the same way as mineral waters. When the milk is
charged at a very high tension for direct consumption without bottling it is placed
in a copper cylinder to about three parts full and charged with carbonic acid gas
from a generator or gas pump at a pressure of about 180 lbs. to the square inch.
The copper cylinder should be tinned inside, and be provided with one or two
connections for filling and drawing off the beverage as may be required for con-
sumption. In all cases the milk should if possible be direct from the cow, and put
through the process before cream is allowed to form.
Having described the nature of my Invention and the manner of performing the
same, I declare that what I claim as my Invention to be protected by the herein-
before in part recited Letters Patent is,--
The manufacture of the improved preparation or beverage consisting of milk
(with or without the addition of some medicament) charged with and preserved by
carbonic acid gas at a high tension, substantially as herein specified.
In witness whereof, I, the said Aubrey Nelson, Inve hereunto set my hand
and seal, this Fifth day of May, in the year of our Lord One thousand
eight bundred and seventy-nine.
