IMPROVE- MENTS IN THE MEANS OF PRESERVING ANIMAL AND VEGETABLE SUBSTANCES
Year: 1874

page_text: LETTERS PATENT to Gabor Naphegyi, of New York City, in the
United States of North America, now temporarily of London Wall,
in the City of London, Merchant, for the Invention of "IMPROVE-
MENTS IN THE MEANS OF PRESERVING ANIMAL AND VEGETABLE SUBSTANCES."
.
PROVISIONAL SPECIFICATION left by the said Gabor Naphegyi at
the Office of the Commissioners of Patents, with his Petition, on
the 6th March 1874.
I, GABOR NAPHEGYI, of New York City, in the United States of
North America, now temporarily of London Wall, in the City of
London, Merchant, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MEANS OF PRESERVING ANIMAL AND VEGETABLE Sub-
STANCES," to be as follows:-
The object of this Invention is the preservation of animal and
vegetable substances, especially slaughtered animals and portions cut
therefrom; also vegetables used for provisions, and dead (human)
bodies.

page_text: The principle of the Invention is the combined employment of the
two agents known in chemistry as ethyl and methyl or compounds con-
taining them. These agents, as I have discovered, will when used in a
close or confined receiver or case containing the substance to be pre-
served, counteract the deteriorating influence of the atmospheric air
or other destructive agency and preserve the substance from decay.
Methyl is the "radical" of wood spirit or methylic alcohol; ethyl is
the radical of ordinary alcohol.
J
According to my Invention I enclose the substance to be preserved in
a close box, chamber, case, or vessel, and through a small aperture
formed therein I inject or introduce both ethyl and methyl, or com-
pounds containing ethyl and methyl or a combination of ethyl and
methyl, or of compounds or matters containing them; after introducing
the said agents I close the aperture carefully.
In carrying out the Invention I prefer to use 1 part of the ethyl to 2
parts of the methyl, both being either in a gaseous or liquid form.
I usually recommend for the purposes of my invention the hydrate
of methyl and the acetate of the oxide of ethyl. These I employ in
solution taking 1 part of the latter to two parts of the former. I place
the meat or other substance to be preserved in a close receiver or case,
but I do not exhaust the air therefrom. I then form a very small
aperture in the cover of the case or receiver just large enough to admit
the spout of the funnel, and through this I pour in the two above-
mentioned solutions so that the animal or vegetable substance may be
bathed in them, and they fill up entirely all the space in the
receiver not occupied by the substance to be preserved. I immediately
withdraw the funnel and close the orifice as air-tight as possible.
I usually find th ounce of the liquid combination to 800 lbs. of the
substance to be preserved is practically satisfactory, but I do not restrict
myself to these proportions. The substance to be preserved remains
any length of time in this solution and when the receiver or case is
opened, and the substance withdrawn therefrom it will be found in a per-
fectly fresh condition.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Gabor Naphegyi in the Great Seal Patent Office
on the 4th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GABOR
NAPHEGYI, formerly of New York City, in the United States of North
America, now of Kensington, in the County of Middlesex, Merchant,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of March, in the year of
our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Gabor Naphegyi, Her special
licence that I, the said Gabor Naphegyi, my executors, administrators,
and assigns, or such others as I, the said Gabor Naphegyi, 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 MEANS OF PRESERVING ANIMAL AND VEGETABLE SUBSTANCES," upon the.
condition (amongst others) that I, the said Gabor Naphegyi, my exc-
cutors 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 immediately
after the date of the said Letters Patent.
...NOW KNOW YE, that I, the said Gabor Naphegyi, 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 thereof, that is to say:-
- The object of this Invention is the preservation of animal and
vegetable substances, especially slaughtered animals and portions cut
therefrom; also vegetables used for provisions, and dead (human)
bodies

page_text: The principle of the Invention is the combined employment of the
two agents known in chemistry as ethyl and methyl or compounds con-
taining them. These agents, as I have discovered, will when used in a
close or confined receiver or case containing the substance to be pre-
served, counteract the deteriorating influence of the atmospheric air or 5
other destructive agency and preserve the substance from decay.
Methyl is the "radical" of wood spirit or methylic alcohol; ethyl is
the "radical" of ordinary alcohol.
According to my Invention I enclose the substance to be preserved in
a close box, chamber, case, or vessel, and through a small aperture 1
formed therein I inject or introduce both ethyl and methyl or compounds
containing ethyl and methyl, or a combination of ethyl and methyl or
of compounds or matters containing them; after introducing the said
agents I close the aperture carefully.
In carrying out the Invention I recommend the employment of 1 part. 1
of the ethyl or compound containing it to 2 parts of the methyl or com-
pound containing it, both being either in a gaseous or liquid form.
I usually recommend as suitable ingredients for the purposes of carrying
out my Invention the hydrate of methyl and the acctate of the oxide of
ethyl. These I employ in solution, taking 1 part of the latter to 22
parts of the former.
In performing the Invention I usually proceed as follows:-I place
the meat or other substance to be preserved in a close receiver or case,
but I do not exhaust the air therefrom; I then form a very small:
aperture in the cover of the case or receiver just large enough to admit 2
the spout of a funnel, and through this I pour in the two above-men-
tioned solutions so that the animal or vegetable substance may be bathed.
in them, and they fill up entirely all the space in the receiver not
occupied by the substance to be preserved. I immediately withdraw
the funnel and close the orifice as air-tight as possible.
3
I usually find th ounce of the liquid combination to 800 lbs. of the
substance to be preserved is practically satisfactory, but I do not restrict
myself to the proportions herein mentioned. The substance to be pre-
served remains any required length of time in the solution, and when
the receiver or case is opened and the substance withdrawn therefrom, 3
it will be found in a perfectly fresh condition.

page_text: The ethyl and methyl or the agents or compounds containing them
may be used for the purposes of my Invention in a gaseous or aeriform
state as well as in the liquid state; ordinary gas injecting arrangements
being in that instance combined with the case containing the substances
to be preserved; also the parts used, say 1 part of the ethyl or its com-
pounds, and 2 parts of the methyl or its compounds may be taken by
weight.
Having now described the nature of the said Invention and in what
manner the same is to be performed I declare that I claim, the employ-
ment of the means herein-before described for preserving animal and
vegetable substances.
In witness whercof, I, the said Gabor Naphegyi, have hereunto
set my hand and scal, this Twenty-fourth day of August, in
the year One thousand eight hundred and seventy-four.
Witness,
HENRY CONYBEARE.
