1, JULES HAUTRIVE, of Lille, France, Manufacturer, do hereby declare the
nature of said invention for A.NEW OR IMPROVED COMPOUND FOR PROTECTING
METALS FROM CORROSION OR OXYDATION AND FOR OTHER PURPOSES, to be na
follows:-
My invention relates to a compound or mixture with a plumbagine base,
preserving metals from corrosion or oxydation, and rendering any object impu-
trescible. The said compound consists either of bitumen, drying oil, varnish, tar,
liquid india rubber, gutta percha, or any other similar substance, in which I mix
a carbon (in impalpable powder) known by the names of graphite or plumbagine,
combined with turpentine or alcohol, according to the nature of the compound, so
that it may be applied with a brush like ordinary paint, especially that containing
red lead, for which it is an excellent substitute, upon iron, cast or wrought, wood
or other materials.
Plumbagin, commonly called black lead is a fatty matter, penetrating_and
imbedding itself in the pores of iron, wood or other materials; it preserves thom
better than the oxydes of lead, zinc, or other matters which tend to continue their
oxydising and consequently decomposing action.
This composition is thoroughly preservative (this carbon being proof against
acids, and naturally against the air of the atmosphere) and may be employed as
a first coat in any painting operation.
After it has been applied, it may in certain cases bo burnished, as is done in
gilding and silvering work, and a bright steel appearance is obtained.
It is suitable for application upon iron, cast or wrought, wood, slate, zinc, paper,
cloth and paste board for roofing, wagons, tramway cars, carriagos, tarpaulin,
stone, cement, and other materials.
Therefore, instead of fixing the plumbagine in powder by means of a pigment
or size, as in the case of bronzing powders, I manufacture a compound, chiefly of
bitumen, turpentine, and of plumbagin in powder, to which a coloring mineral may
be added in the proportions of about a gallon of asphalte or Jew's pitch, or of
Japan varnish, two quarts of turpentine, and about 1 lb. 5 oz. of plumbagin in
impalpable powder.
This mixture dries quickly, and one coat is sufficient.

of my invention for A NEW OR IMPROVED COMPOUND FOR PROTECTING METALS

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My invention relates to a compound or mixture with a plumbagine baso,
preserving metals from corrosion or oxydation and rendering any object impu-
trescible. The said compound consists either of bitumen, drying oil varnish, tar
liquid, india rubber, gutta percha, or any other similar substance in which I mix
a. carbon (previously reduced to an impalpable powder) known by the names of
graphite or plumbagino combined with turpentine or alcohol according to the
nature of the compound, so that it may be applied with a brush like ordinary
paint such as so-called red lead paint for which it is an excellent substitute when
applied upon iron, (cast or wrought,) wood or other materials.
Plumbagine commonly called black lead is a somewhat greasy matter penetrating
and imbedding itself in the pores of iron wood or other materials when applied
thereto as described, it preserves them better than the oxydes of lead, zinc, or other
matters which have a tendency to continue their oxydising and consequently
decomposing action.

This composition is thoroughly preservative (this carbon being proof against
acids and naturally against the air of the atmosphere) and may be employed as a
first coat in any painting operation.
After it has been applied it may in certain cases be burnished as is done in
guilding and silvering work and a bright steel appearance will be obtained.
It is suitable for application upon iron, (cast or wrought,) wood, slate, zinc,
paper, cloth, and paste-board, for roofing, wagons, tramway cars, carriages, tarpaulin
stone, cement and other materials and therefor instead of fixing.the powdered
plumbagine by means of a pigment or size, as in the caso of bronzing powders the
compound is manufactured chiefly of bitumen turpentine and of plumbagine in
powder to which a colouring mineral may be added the components of the
composition being, for instance in the proportions of about one gallon of asphalte
or Jew's pitch or of Japan varnish two quarts of turpentine and about 1 lb 5 oz of
plumbagine in impalpable powder,
This mixture dries quickly and one coat is sufficient.

Invention and in what manner the same is to be performed, I declare that what
I claim is
The new or improved compound for coating or protective purposes as herein
specified.
