I, JOSEPH MCGILLIVRAY, Manager of The Downie Boiler Incrustation
Preventive Company, of 4 Redcross Street, Liverpool Lancashire, do hereby
declare the nature of this invention to be as follows:-
My invention relates to certain improvements for the prevention of corrosion of
iron steel or other metal surfaces.
It consists in the use of an aqueous or spirituous extract of eucalyptus leaves or
of an intimate mixture of the same with any suitable gums, resin, varnishes,
linseed oil, glycerine, wax, tallow, soft soap or algin, as a coating for the metal
surfaces which it is wished to preserve from corrosion.
The extract or mixture may be laid on by a brush in the ordinary manner or in
any other suitable way; and if desired, it may be used warm, or the metal to be
coated may be first slightly heated.

I, JOSEPH MCGILLIVRAY, Manager of The Downie Boiler Incrustation
Preventive Company, of 4 Redcross Street, Liverpool, Lancashire, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:—
This invention relates to certain improvements for the prevention of corrosion
of iron, steel or other metal surfaces.
It consists in the use of an aqueous or spirituous extract of eucalyptus leaves,
or of an intimate mixture of the same with any suitable gums, resins, varnishes,
linseed oil, glycerine, wax, tallow, soft soap or algin, as a coating for the metal
surfaces which it is wished to preserve from corrosion. The extract used is of
an 80 strength by Twaddell's alkali test.
In producing my improved preservative coating, I first obtain a fluid or aqueous
extract of eucalyptus leaves by means of boiling them in water and straining off
the resultant fluid. The gum or other resinous substance is afterwards added to
the fluid so obtained in the following approximate proportions :-
Gum or resin, varnish, linseed oil, glycerine,
wax, tallow, soft soap or algin
Eucalyptus fluid
:-
-
-
1 and a-half pounds by weight;
1 gallon ;
and an intimate mixture of these constituents is obtained by thoroughly boiling
them together in a suitable vessel.

page_text: The mixture or composition produced as above described may be laid on by a
brush in the ordinary inanner, or in any other suitable way, preferably in a cold
state upon the surface of the metal to be coated; or it may if desired be used
while warm; or the metal to be coated may be slightly heated before the
composition is applied thereto.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
A composition for coating and preserving from corrosion, surfaces of steel, iron
or other metals, consisting of an intimate mixture of gums, resins, varnishes,
linseed oil, glycerine, wax, tallow, soft soap or algin, with fluid extract of
eucalyptus leaves in the proportions and by the method specified.
