Improved Non-corrosive, Preserving, and Fire-resisting Paint.
We THE NON-CORROSIVE, PRESERVING AND FIRE-RESISTING PAINT COMPANY
LTD. and FRANK WHITE, Silversmith, and JAMES THOMSON, Tailor, all of
71 Cathedral Square, Christchurch, in the Colony of New Zealand, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention provides an improved non-corrosive, preserving and fire-resisting
paint for employment upon wood, iron, ship-plates and other substances.
For use upon the surface of ship-plates and other objects exposed to the action
of sea water, our paint is composed of the following ingredients, the proportions
given being those we have found most useful in practice but variable within
certain limits without materially affecting the result.
Sulphuric Acid, one quarter ounce; Turpentine half ounce; Liquid Ammonia,
one eighth ounce; Chloride of Copper, Chloride of Zinc, Nitrate of Mercury and
Cyanide of potassium of each One pennyweight; Linseed oil one half pound, and
sufficient flake white or other paint base to make a paint of the usual consistency.
In manufacture the flake white or other paint base is mixed with the Linseed
oil as in making ordinary paint.
The Turpentine is added to the Sulphuric Acid in a separate vessel and then the
Ammonia, the resulting liquid is now stirred into the paint base and oil, and the
Chloride of Copper, Chloride of Zinc, Nitrate of Mercury, and Cyanide of Potassium
put in. A sufficient quantity of driers may be used as in ordinary paint.
For painting upon wood, and other substances not exposed to the action of sea
water, all or either of the Chloride of Copper, Chloride of Zinc, Nitrate of
Mercury, and Cyanide of Potassium may if desired he omitted.
It is possible to make naint of any usual color of commerce by using instead
of, or in addition to, Flake white the coloring material of ordinary paint.
We have found that inflammable articles covered with our paint offer con-
siderable resistance to fire and that it has great preservative and anti-corrosive
qualities when used upon iron or steel plates exposed to the action of salt water.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. Paint in the manufacture and composition of which the following ingredients
are employed: Flake white (or other usual paint base) Linseed Oil, Sulphuric
Acid, Turpentine and Ammonia, substantially in the proportions and in the
manner herein specified.
2. Paint in the manufacture and composition of which the following ingredients
are employed: Flake white (or other usual paint base) Linseed Oil, Sulphuric
Acid, Turpentine and Ammonia, Chloride of Copper, Chloride of Zinc, Nitrate
