PROVISIONAL SPECIFICATION left by the said John Henry Ermatinger at
the Office of the Commissioners of Patents on the 2nd February 1876.
JOHN HENRY ERMATINGER, of Dunster House, Mincing Lane, London, E.C. « A
NEW OR IMPROVED METHOD OF PRESERVING EGGS FRESH."
This Invention consists in covering eggs with a certain coating. This coating is
obtained by immersing them into siccative poppy oil and then exposing them to
the air until the oil has become dry. A second coating may be given by repeating
the process.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Henry Ermatinger in 'the Great Seal Patent Office on the
2nd August 1876.
JOHN HENRY ERMATINGER, of Dunster House, Mincing Lane, London, E.C.
NEW OR IMPROVED METHOD OF PRESERVING EGGS FRESH." A communication
from abroad by Doctor Frederick H. L. C. Sace, Professor of Chemistry, of
Neuchâtel, Switzerland.
This Invention consists in covering or providing eggs with a certain coating.
This coating is obtained by immersing the eggs to be preserved, preferably when
they are not older than 3 days, for one minute into siccative poppy oil, then exposing
them to the air; thus allowing the superfluous oil to drip off and the coating to be
formed over the whole surface of the eggs. Whilst the eggs are under treatment
it is of course well that they should be touched as little as possible, so that the
coating inay become perfect all round the eggs; it is only when and if some points
on their surface should still be without a sufficient coating (by reason of having
been touched) that the repetition of the process in order to produce a second coating

treatinent it is expedient to place them at the outset on a sort of hurdle of
galvanized iron wire or other suitable material, the hurdle having raised edges to
prevent the eggs from rolling off, and a handle at each end by means of which they
can conveniently be immersed in the siccative poppy oil (standing ready for use in
a suitable trough) and lifted out again for exposure to the air without handling
them at all. It is well not to store away the eggs until the coating has become
sufficiently dry. The said coating, which ressembles a sort of caoutchouc, closes the
pores of the egg and prevents at the same time both the water to evaporate from
and the air to enter into the. egg without, imparting to it any unpleasant flavour,
thus preserving it in its fresh state.
'Having now, fully described and ascertained the nature of this Invention, and the
manner in which the same is to be carried out, I would have it clearly understood
that what I claim under my Letters Patent, No. 423, is, the employment of siccative
poppy oil, either pure or mixed to some extent with any other suitable siccative oil
or suitable substance that would readily combine with it, for preserving eggs fresh,
substantially as described.
In witness whereof, I, the said John Henry Ermatinger, have hereunto set
my hand and seal, this Second day of August, in the year of our Lord
One thousand eight hundred and seventy-six.
(L.S.) J. H. ERMATINGER.
