Year: 1856

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IMPROVE-
MENTS IN PRESERVING PROVISIONS."-A communication from Garnier
Brothers Faucheux Tison and Company.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 8th November 1856.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PRESERVING PROVISIONS," (communicated to me by Garnier
Brothers, Faucheux, Tison, and Company, foreigners residing abroad,) to be
as follows:-
This Invention consists in the employment for the preservation of provisions
of an extract, infusion, or product derived from carragohem, or other moss, fucus
crispus, varec, kelp, sea-wrack, or other substance susceptible of yielding a
similar extract, or of any matter containing iodine; and the Invention also
consists in employing stearine or other fatty or greasy matter for closing or
sealing the cases or receptacles containing the provisions to be preserved.
In employing the Invention for preserving meat, it is as well to mix the
aforesaid extract with an extract obtained from boiling down cartilages or

page_text: ment, and after pouring the combined extracts into the case containing the
meat (which has been previously sprinkled with saltpetre), and sealing it with
stearine or other like body, it is boiled in a digester. Salt or other agent for
checking the liberation of steam is recommended to be mixed with the water
in the digester.
BPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 5th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Eighth day of November, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Richard
Archibald Brooman, Her special licence that I, the said Richard Archibald
Brooman, my executors, administrators, and assigns, or such others as I,
the said Richard Archibald Brooman, 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
night 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 PRESERVING PROVISIONS," (communicated to me by Garnier
Brothers, Faucheux, Tison, and Company, foreigners residing abroad,) upon
the condition (amongst others) that I, tho said Richard Archibald Brooman,
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 Offico.
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is to
bo performed, to be particularly described and ascertained in and by the
following statement thereof, that is to sny :-
This Invention consists in the employment for the preservation of provisions
of an extract, infusion, or product derived from carragohem or other moss,

page_text: varec, fucus crispus, kelp, sea-wrack, or other substance capable of yielding a
similar extract, or of any matter containing iodine; and the Invention also
consists in employing stearine or other fatty or greasy matter for closing or
sealing the cases or receptacles containing the provisions to be preserved. In
employing the Invention for preserving meat, it is as well to mix the aforesaid
extract with an extract obtained by boiling down cartilages or meat, and after
pouring the combined extracts into the case containing the meat, which has
been previously sprinkled with saltpetre, and sealing it with stearine or other
like body, it is boiled in a digester. Salt or other agent for checking the
liberation of steam is recommended to be mixed with the water in the
digester.
In order that the method of carrying the Invention into effect may be fully
understood, the following detailed description of the mode of preserving meats
and sardines or other fish is given.
THE PRESERVATION OF MEATS.
Whatever may be the nature of the meat to be preserved it is cut up into
pieces, which are sprinkled with saltpetre, packed closely in a case or box (or
cases or boxes) formed of tin, and have poured upon them, in sufficient
quantity to completely fill the case or box, a concentrated, liquid formed as
follows:-Waste or other pieces of meat or cartilage are boiled in water until
a gravy or liquid is produced, which on cooling forms a jelly, and with this is
mixed a second liquid obtained by boiling down varec, carrogohem moss, or
other such substance in water until the liquid becomes of about the same con-
sistence as the former. These liquids are mixed while warm, and in about
equal proportions, and when poured into the case or box fill up all the
interstices between the pieces of meat contained therein, and also saturate the
meat itself, which it has the property of preserving; the case or box is then
closed or sealed by means of an odourless and tasteless (or very nearly so)
fatty body, such as stearine or purified grease, the employment of resinous
and other similar bodies being carefully avoided. The case or box being
hermetically sealed, or as nearly so as possible, is plunged in boiling water
which has been charged with salt, as above mentioned, to check the liberation
of steam, and thus induce a higher degree of heat than would otherwise be
obtained.
THE PRESERVATION OF SARDINES.
The sardines to be preserved are baked in an oven while fresh, and then
placed in a tin case or box (or cases or boxes), as is usual in preserving
sardines in oil, but instead of oil an extract of varec, carragohem moss, or

page_text: other such substance is used, which is prepared as follows:-About 2 lbs. of
dry varec (supposing that to be the substance selected) is infused in about
10 pints of fresh water for 24 hours, after which the liquid is decanted and an
equal quantity of fresh water is placed upon the same varee, and heated in a
porcelain or other suitable vessel until about 83 per cent. of the water is
evaporated. A liquid of about the same consistence as those beforo mentioned
is thus obtained, and this is poured into the case or box containing the sardines
until the same is full. The process is then proceeded with as in the preserva-
tion of meat above described: Or, instead of the liquid obtained by boiling
down the varee, a liquid obtained by boiling down any other analagous marine
substance to about the same consistence may be employed, but varce is pre-
ferred by the Inventors as the most economical.
And having now described the nature of tho said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the employment for preserving provisions of extracts obtained from
carragohem or other moss, from varee of every description, from kelp, from
sea-wrack, and from other substances capable of yielding similar extracts.
Secondly, the employment for preserving provisions of substances containing
iodine.
Thirdly, the employment in preserving provisions of stearine and other fatty
bodies free from resin, for the purpose of closing or sealing the cases or boxes
containing such provisions.
Fourthly, the methods of preserving provisions herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fifth day of May, One thousand
eight hundred and fifty-seven.
