CERTAIN IMPROVEMENTS IN THE MODE OF PRESERVING ANIMAL AND VEGETABLE SUBSTANCES
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
WARINGTON, of Apothecaries' Hall, in the City of London, Chemist, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fifth day of March, in the ninth year of Her reign, did, for Her-
self, Her heirs and successors, give and grant unto the said Robert Wa-
rington, Her special licence, that I, the said Robert Warington, my exors,
adñors, and assigns, or such others as I, the said Robert Warington, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, and in the Islands of Jersey,
Guernsey, Alderney, Sark, and Man, and also in all Her said Majesty's Colonies
and Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN THE MODE
OF PRESERVING ANIMAL AND VEGETABLE SUBSTANCES;" in which said Letters Patent
is contained a proviso obliging me, the said Robert Warington, by an in-
strument in writing under my hand and seal, particularly to describe and ascer-
tain the nature of my said Invention, and in what manner the same is to be
performed, and to cause the same to be enrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said Robert
Warington, do hereby declare the nature of my said Invention to consist,

page_text: first, in coating the substances to be preserved with common glue, gelatine,
or concentrated meat gravies, or otherwise, so as to make an air-tight skin,
film, or covering over the whole substance; and, secondly, in keeping
substances so coated or other substances to be preserved constantly immersed
and submerged in glycerine, treacle, elaines, oils, and other the like matters
contained in tight, but it may be open vessels, from which they are only to be
And in further compliance with the said proviso, I, the
said Robert Warington, do hereby describe the manner in which my said
Invention is to be performed by the following statement thereof; that is to
say:-
removed for use.
First, I prepare a vessel of warm glue, gelatine, or very strong concentrated
meat gravy, and having suspended the piece of meat or other substance to be
preserved by a string, dip it into the vessel, so that the substance shall be com-
pletely covered, and I repeat this, allowing each coating thus obtained to dry
until I have a hard film or skin of the thickness required over the whole surface
of the substance to be preserved. Or I proceed in the following manner:-I
prepare a vessel of thin cream of plaster of Paris and water, and dip the sub-
stance to be preserved in it until a film or coating becomes set hard all over
the surface, and then saturate this film with melted suct, stearine, wax, or other
matter that will render it impervious to the air. Or I proceed in the following
manner: I wrap the substance to be preserved very carefully and tightly round
with a thin strip or band of caoutchouc or gutta percha, or other air-tight mem-
brane, such as waterproof cloth, making each turn lap a little over the other,
and when completely covered in every part, and when caoutchouc or gutter
percha is used, I plunge it into boiling water, and thus cement the edges of the
band together, so that it forms one compact and unbroken covering, or having
wrapped the band round the substance to be preserved as aforesaid, I cement
the edges together with a cement of indian rubber or gutta percha, to be dis-
solved in rectified spirits of turpentine, bisulphuret of carbon, or other solvent
or any other air-tight cement, as the case may be. Or I proceed in the fol-
lowing manner :-I cover or paint the surface of the substance to be preserved,
either before or after any of the last three mentioned operations, with a varnish
or cement of caoutchouc or gutta percha, as before described, or other air-tight
varnish or cement.
Secondly, I keep the substances so coated as aforesaid, and the other
substances to be preserved, constantly immersed and submerged in glycerine,
treacle, elaines, oils, and other the like matters, not liable to such oxidation
decomposition, or other change from exposure to the atmosphere as would
prevent the preservation of the substances to be preserved, these matters afore-

page_text: said being kept in tight, but it may be open vessels, and the substances only
disturbed when removed for use. Note, in all cases of meats for the table, I
prefer that they should be half cooked by boiling or roasting before coating or
submersion, and when oils are used I prefer that they should be heated to
about two hundred and twenty degrees of Fahrenheit before the substances to
be preserved are introduced, at which temperature they should be introduced,
and the whole then allowed to cool. And in the case of oils, fats, or waxy
substances presenting a solid appearance at the ordinary temperatures of the
atmosphere, they should of course be warmed and melted previous to the im-
mersion and submersion in them of the substances to be preserved. Now,
whereas, I claim as my Invention,-
First, the coating of animal and vegetable substances as herein before
described for the purposes of preservation.
And, secondly, the immersion and keeping submerged of such coated or of
other animal and vegetable substances in glycerine, treacle, elaines, oils, and
other the like matters which are not liable to such oxidation, decomposition,
or other change from exposure to the atmosphere as would prevent the pre-
servation of the substances to be preserved, these matters aforesaid being
kept in tight, but it may be open vessels, and the substances aforesaid only
disturbed when removed for use.
And such my Invention being, to the best of my knowledge and belief, entirely
new and never before used within that part of Her said Majesty's United
Kingdom of Great Britain and Ireland called England, Her Dominion of
Wales and Town of Berwick-upon-Tweed, nor in the Islands of Jersey,
Guernsey, Alderney, Sark, and Man, nor in any of Her said Majesty's Colonies
and Plantations abroad, I do hereby declare this to be my Specification of
the same, and that I do verily believe this, my said Specification, doth comply
in all respects fully and without reserve or disguise, with the proviso in the said
herein-before in part recited Letters Patent contained; wherefore I hereby
claim to maintain exclusive right and privilege to my said Invention.
In witness whereof, I, the said Robert Warington, have hereunto set
my hand and seal, the Fourth day of September, One thousand eight
hundred and forty-six.

page_text: AND BE IT REMEMBERED, that on the Fourth day of September, in the
year of our Lord 1846, the aforesaid Robert Warington came before our said
