PROVISIONAL SPECIFICATION.
An Elastic Antiseptic or Preservative Coating for Fruit, Eggs and
other Perishable Goods.
I, JOHN DENIS COAKLEY, of No. 117, Wellington Street, Flemington, in the
Colony of Victoria, Accountant, do hereby declare the nature of this invention,
to be as follows:
This invention relates to an elastic antiseptic or preservative coating for
fruit, eggs and other perishable goods, the component parts of which consist
of glycerine, gelatine and salicylic acid or their chemical equivalents with the
addition for some purposes of gutta-percha. The object being to cover such
fruit and goods with a clear transparent substance which excludes air.
In preparing the composition for coating such as apples, pears or other fruits,
or as an antiseptic coating for eggs; I mix the ingredients in about the fol-
lowing proportions. I first dissolve about one pound of gelatine and add to it
about two ounces of the salicylic acid, when dissolved to the consistency of a
paste, then I heat the mixture and add about two ounces of glycerine and allow
the compound to simmer and so become thoroughly mixed, then the compound
is allowed to cool down to about a blood heat, when the fruit or eggs may be
dipped or steeped in the liquid compound and removed and allowed to dry.
When dry the fruit or eggs will be found to be enveloped in a thin flexible
coating. In preparing the mixture for coating fruit, I prefer to add a flavouring
ingredient, corresponding with the fruit which is to be coated. When it is
desired to coat the walls of such as jam tins or the like, I prefer to add a small
quantity of gutta percha to the above described composition and which can
be applied to the internal surface of the tin. jar or canister, with a brush.

In preparing the composition for coating such as apples, pears or other fruits
or as an antiseptic coating for eggs, I mix the ingredients in about the fol-
lowing proportions. I first dissolve about one pound of gelatine in water and
add to it about one and a half ounces of the salicylic acid when dissolved to the
consistency of a paste in about 10 ounces of warm water then add about two
ounces of glycerine and allow the compound to simmer and so become thoroughly
mixed. The compound is now allowed to cool down to about blood heat, when
the fruit or eggs may be dipped or steeped in the liquid compound and removed
and allowed to dry. When dry the fruit or eggs will be found to be enveloped
in a thin flexible coating. In preparing the mixture for coating fruit I prefer
to add a flavouring ingredient corresponding with the fruit which is to be
coated.
In preparing an antiseptic covering or packing for eggs which are to be
exported I make up the composition in about the follownig proportions:-
Gelatine 1 ounce; glycerine 20 ounces; salicylic acid 2 drams and water 30
ounces. These are mixed together and made up into the form of a warm liquid
which is poured into a liquid tight case or package and when the compound
cools each egg will be completely covered or coated with the compound. If so
preferred the egg may be first packed in cardboard or other pockets prior to
the liquid compound being poured upon them.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The herein described elastic antiseptic or preservative compound consisting
essentially of an admixture of gelatine, glycerine, salicylic acid and water in
about the proportions stated and as and for the purposes described.
