Year: 1874

page_text: LETTERS PATENT to Charles Augustus Lippincott, of Aylesbury, in
the County of Bucks, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF CONDENSED MILK."-A communication from abroad
by George Conklin, of New York, in the United States of
America.
PROVISIONAL SPECIFICATION left by the said Charles Augustus
Lippincott at the Office of the Commissioners of Patents, with his
Petition on the 19th January 1874.
¡ I, CHARLES AUGUSTUS LIPPINCOTT, of Aylesbury, in the County of
Bucks, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF CONDENSED MILK," a communication to me
from abroad by George Conklin, of New York, in the United States of
America, to be as follows:-
This Invention relates to an improved process for making condensed
milk without sugar, by which the flavor and consistency of the milk are
improved, and the milk is also better preserved than by the ordinary

page_text: process of condensing, whilst the product is almost free from any flavour
acquired by boiling.
In carrying out this Invention the milk is first condensed in a vacuum
pan in the usual manner, but at the close of the process the vacuum is
broken, after which a quantity of crude milk or water is added to the
condensed milk in the vacuum pan, and the heat raised to a temperature
exceeding 150 degrees Fahrenheit.
filed by the said Charles Augustus Lippincott in the Great Seal
Patent Office on the 18th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
AUGUSTUS LIPPINCOTT, of Aylesbury, in the County of Bucks, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of January, in the year
of our Lord One thousand eight hundred and seventy-four, in the 37th
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Augustus Lippincott, Her special license
that I, the said Charles Augustus Lippincott, my executors, administrators,
and assigns, or such others as I, the said Charles Augustus Lippincott,
my executors, administrators, or 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 Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF CONDENSED MILK," a communi-
cation to me from abroad by George Conklin, of New York, in the
United States of America, upon the condition (amongst others) that I,
the said Charles Augustus Lippincott, my executors or administrators,
by an instrument in writing under my hand and seal, should par-
ticularly 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.

page_text: NOW KNOW YE, that I, the said Charles Augustus Lippincott, 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, that is to say :-
This Invention relates to an improved process for making condensed
milk without sugar, by which the flavor and consistency of the milk are
improved, and the milk is also better preserved than by the ordinary
process of condensing, whilst the product is almost free from any flavour
acquired by boiling.
In carrying out this Invention the milk is first condensed in a vacuum
pan in the usual manner, but at the close of the process the vacuum is
removed or broken, after which crude milk or water or mixtures of the
same in the proportion of say not less than three or more than five per
cent. of the original quantity of the milk which has been condensed is
added to the condensed milk in the vacuum pan, and the heat raised
from a temperature from about 150° to 190° Fahrenheit.
In practice I have found that a temperature of about 165° Fahrenheit
give the best results.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I consider
to be novel and original and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, mixing crude
milk or water or mixtures of the same with condensed milk, and then
heating the mixture, substantially as and for the purpose herein-before
described.
In witness whereof, I, the said Charles Augustus Lippincott, havo
