PROVISIONAL SPECIFICATION.
A New or Improved Composition or Paint to be Used for
Coating and Preserving Metal, Wood, and other Substances and
Materials,
I, WALTER CHIDIOCK NANGLE, of 17 Manson Place, Queen's Gate, in the County
of Middlesex, Colonel late Royal Artillery, do hereby declare the nature of this
Invention to be as follows:-
My Invention relates to a new or improved composition or paint to be used for
coating and preserving iron or other metal, also for covering hot surfaces, such as hot
water pipes, stove pipes, funnels &c., wood and other substances and materials, and
in manufacturing or preparing such composition or paint I proceed as follows:
I first boil together coal tar, pitch, or bitumen and cow dung until the same be
intimately incorporated, and I then strain the liquor. The mixture thus obtained is
then tanned, that is to say, it is boiled with oak-bark, or other suitable tanning
material. The residue of the tan is then strained off and the liquor is boiled with
rosin and sulphur. When cool, it is thinned out by the addition thereto of turpentine,
benzoline, methylated spirit, or other suitable dilutant. Finally, gypsum is added,
and the whole thoroughly mixed, or the gypsum may be boiled with the above.
This paint or composition will be found especially useful for preserving metal, the
metal appearing to readily imbibe it. In some instances, and as an additional means
of preventing the corroding or rusting of metal, or the deterioration or decay of
wood, I may, prior to coating whatever surface has to be painted or preserved, rub
the same with chalk, this being a most efficacious way of preventing the ravages of
rust or corrosion of iron, or other metal, and the decay in wood.

Materials.

1, WALTER CHIDIOCK NANGLE, of 17 Manson Place, Queen's Gate, in the County
of Middlesex, Colonel late Royal Artillery 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, that is to say:-
My invention relates to a new or improved composition or paint to be used for
coating and preserving iron, or other metal, also for covering hot surfaces, such as
hot water pipes, stove pipes, funnels &c., wood, and other substances and materials,
and in manufacturing or preparing such composition or paint I proceed as follows.
I first boil together coal tar, or pitch, or bitumen, or any combination of these, and
cow dung, until the same be intimately incorporated, and I then strain the liquor.
The mixture thus obtained is then tanned, that is to say it is boiled with oak bark,
or other suitable tanning material. The residue of the tan is then strained off and
the liquor is boiled with rosin, sulphur and gypsum (i.e. plaster of Paris) and the
whole mixture now passed through a grinding mill. When cool it is thinned out by
the addition thereto of turpentine, benzoline, methylated spirit, or other suitable
diluant.
This paint or composition will be found especially useful for preserving metal, the
metal appearing to readily imbibe it. In some instances, and as an additional means

may, prior to coating whatever surface has to be painted or preserved, rub the same

In carrying out my Invention I preferably use the ingredients in the following
proportions :-
may, prior to coating whatever surface has to be painted or preserved, rub the same
with chalk, this being a most efficacious way of preventing the ravages of rust or
corrosion of iron or other metal, and the decay in wood.
In carrying out my Invention I preferably use the ingredients in the following
proportions:-
Coal tar, or pitch, or bitumen, or a combination of coal tar
and pitch-
Cow dung
Bark (or other suitable tanning material)
Sulphur
Rosin
Gypsum
Turpentine (or other suitable thinning material)
56 gals.

26 gals.
The coal tar, pitch, or bitumen is first boiled with the cow-dung for about an hour,
after which the cow dung is strained off and the mixture then boiled with the bark,
or other suitable tanning material, for about 24 hours. The tanning material is then
strained off, and the rosin and sulphur are next introduced, the heat being kept up
and the mixture well stirred until these latter ingredients are thoroughly dissolved,
and finally the gypsum is thrown in, the mixture being still kept well stirred.
Where it is possible, I prefer to pass the mixture through a grinding machine to
ensure its becoming perfectly smooth and free from all lumps. When cool, turpentine
or other suitable thinning material, is added, and a composition or paint is thus
produced suitable for preserving all kinds of goods made of metal, wood, or other
substances and materials.
When the composition is heated before being used, or when the materials to be
coated or painted with the composition are in a heated state, it is unnecessary to use
any thinning material.
Although the proportions stated above give good results, I do not confine myself
to the exact proportions there mentioned, as they may be varied, without departing
from the nature of my Invention, to suit the requirements of the various classes of
goods to be coated or painted.
Having now described my Invention and in what manner the same may be carried
out, I claim
The improved composition or paint composed of the ingredients herein described
and combined in or about the proportions specified.
