Year: 1871

page_text: LETTERS PATENT to Thomas Frederick Henley, of St. George's Square,
Pimlico, in the County of Middlesex, Gentleman, for the Invention
of "IMPROVEMENTS IN THE TREATMENT OF LIQUID ORGANIC SUBSTANCES FOR
THE PRESERVATION OF THE SAME FROM DECAY."
Sealed the 23rd January 1872, and dated the 24th November 1871.
PROVISIONAL SPECIFICATION left by the said Thomas Frederick
Henley at the Office of the Commissioners of Patents, with his
Petition, on the 24th November 1871.
I, THOMAS FREDERICK HENLEY, of St. George's Square, Pimlico, in
the County of Middlesex, Gentleman, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE TREATMENT OF LIQUID ORGANIC
SUBSTANCES FOR THE PRESERVATION OF THE SAME FROM DECAY," to be as
follows:

page_text: organic fluids. This I propose to effect by availing myself of the proved.
antiseptic properties of meat extract, concentrated beef tea, or meat
essences and dry gelatine. The meat juice that has been obtained by
pressure from raw meat according to the process for which I obtained
Letters Patent bearing date May 6th, 1871, No. 1233, may be combined &
with meat extract in equal or other proportions, and the combined
product is in a fit condition for use in making soups and gravies. This
combined product contains all the nutritive constituents of meat.
When concentrated meat essence or beef tea is used as the preservative
material, it may contain say about 50 per cent. of water. As the
gelatinous constituents of such meat essence or concentrated beef tea
renders the same solid at ordinary temperatures, it is necessary that it
should before use be liquified by the application of heat in order to
facilitate its combination with the raw meat juice.
When gelatine or gelatinous compounds are employed, as the anti-
septic, the application of heat will be required to reduce the same to a
liquid state preparatory to mixing it with the expressed juices or other
nutritious organic fluid matter.
The compound produced by the above admixtures of the juices may
be packed in jars, animal membrane, tins, or cast in cakes for market

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Frederick Henley in the Great Seal Patent
Office on the 24th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
FREDERICK Henley, of St. George's Square, Pimlico, in the County of
Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of November, in
the year of our Lord One thousand eight hundred and seventy-one,
in the thirty-fifth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Thomas Frederick Henley,
Her special licence that I, the said Thomas Frederick Henley, my
executors, administrators, and assigns, or such others as I, the said

page_text: Thomas Frederick Henley, 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 Invention for "IMPROVEMENTS IN THE TREATMENT OF LIQUID
ORGANIC SUBSTANCES FOR THE PRESERVATION OF THE SAME FROM DECAY," upon the
condition (amongst others) that I, the said Thomas Frederick Henley,
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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Frederick Henley, 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) :-
The object of this Invention is to preserve from decay or deterioration
the juices extracted from meat by cold pressure. This I propose to
effect by availing myself of the proved antiseptic properties of meat
extract, concentrated beef tea, or meat essences and dry gelatine. The
meat juice that has been obtained by pressure from raw meat according
to the process for which I obtained Letters Patent bearing date, May
Sixth, One thousand eight hundred and seventy-one, No. 1233, may
be combined with meat extract in equal or other proportions, and the
combined product is in a fit condition for use in making soups and
gravies.
"
The meat extract I propose to prepare by boiling down the bones and
the trimmings obtained from the meat during its preparation for the cold
press. This boiling I continue until I obtain the result well known to
cooks by the term "stock which becomes solid when cool. The
degree of concentration which I prefer to give to this stock or meat
extract will be such as to ensure for it when cold a solidity equal to that
obtained by combining dry gelatine and water in equal parts.
Before using the meat essence thus prepared I heat it in a suitable
vessel and pass it through a cooling worm, and thereby reduce its

page_text: temperature to about one hundred and twenty degrees during its passage
to the mixing vessel. Into this vessel I run the juices from the raw
meat and by the use of a stirrer ensure a thorough mixture of the same.
When the compound is thus prepared it can be run off into moulds to
form cakes, or it may be received into tins, or jars, or animal membranes
when it will be fit for the market.
When using concentrated beef tea as the preservative material it may
contain, say about fifty per cent. of water. When gelatine is used for
the like purpose I combine say two parts of dry gelatine with three
parts by weight of the raw juices, and having reduced the gelatine by
the application of heat to a liquid state I mix therewith the raw meat
juices and obtain the compound desired, which may be packed in jars,
tins, or animal membrane, or cast in cakes for the market.
Having now described my Invention of "Improvements in the
Treatment of Liquid Organic Substances for the Preservation of the
same from Decay" and explained the manner of carrying the same into
effect, I wish it to be understood that under the above in part recited
Letters Patent I claim, applying the antiseptic properties of extract
of meat, of concentrated beef tea, and of dry gelatine to the preservation
of the juices discharged from raw meat in the manner and for the
purpose above described.
In witness whereof, I, the said Thomas Frederick Henley, have
hereunto set my hand and seal, the Twenty-third day of May,
in the year of our Lord One thousand eight hundred and seventy-
