PROVISIONAL SPECIFICATION.
An Improved Paint.
A communication to me from Dr. JOHN W. OVERTON, of Louisville, in the
State of Kentucky, United States of America.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows :-
This invention relates to an improved paint, to be used for the purposes for which
paints are ordinarily used, but more especially for painting ships' bottoms, and other
surfaces exposed to the action of sea water.
The improved paint is composed principally of the mineral well-known as
"rutile," a dioxide of titanium, which is found in abundance in the United States of
America, in Canada, in many parts of Europe, and in other localities.
This rutile is ground or reduced to a sufficiently fine powder, and is mixed and
thoroughly incorporated with coal tar, bitumen or other liquid bituminous or
asphaltic material or compound, or other hydrocarbon of the like kind. The
proportions of the materials used to form the mixture may be varied more or less,
but it is preferred to use about equal parts of the rutile, and the coal tar or other
hydro-carbon described.
The mixture when complete forms a paint which may be applied to ships' bottoms
and other surfaces in the usual way.
It possesses many advantages. For instance, it is unaffected by salt water, and
forms a perfect protection to the bottom of a ship. It is not injuriously affected by
the heat of the sun, or by a temperature up to about 800° Fahrenheit.
inexpensive, and easily made and used.
Where desired other suitable colouring materials may be mixed with it.
It is
Instead of "rutile," other analogous compounds of titanium may be used, the
essential feature of the invention being the use of such compound of titanium,
instead of oxide of iron or the other materials ordinarily heretofore used, as a paint
for the purposes described.

An Improved Paint.
A communication to me from Dr. JOHN W. OVERTON, of Louisville, in the
State of Kentucky, United States of America.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 :—
This invention relates to an improved paint, to be used for the purposes for which
paints are ordinarily used, but which is especially valuable for painting ships'
bottoms, and other surfaces exposed to the action of sea water.
The improved paint which forms the subject of the invention is composed
principally of the mineral well known as "rutile," a dioxide of titanium, which is

Europe, and in other localities.
This rutile is ground or reduced to a sufficiently fine powder, and is mixed and
thoroughly incorporated with coal tar, bitumen or other liquid bituminous or
asphaltic material or compound, or other hydrocarbon of the like kind.
About equal parts of the rutile, and of the coal tar or other hydrocarbon
described may be used. It is to be understood however that the proportions may
be greatly varied. For instance, an excellent paint is obtained by a mixture of
3 parts of "rutile" to 1 part of asphalt.
When required the mixture may be thinned with naphtha.
The mixture forms a paint which may be applied to ships' bottoms and other
surfaces in the usual way. It possesses many advantages. For instance, it is
unaffected by salt water, and forms a perfect protection to the bottom of the ship.
It is flexible and is not injuriously affected by the heat of the sun, or by a tempera-
ture up to about 800° Fahrenheit. It is inexpensive, and easily made and used.
Where desired other suitable colouring materials may be mixed with it.
Instead of "rutile," as described, which is preferable, other analagous compounds
of titanium may be used, the essential feature of the invention being the use of
such compound of titanium, instead of oxide of iron or the other materials ordinarily
heretofore used, as a paint for the purposes described.
}
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improved paint having for its principal ingredient, rutile or di-oxide of
titanium, and composed substantially in the manner described.
2. The use of oxide of titanium in the manufacture of paint, substantially in the
manner and for the purposes described.
