Blocks for Paving, Cement for Walls, and other purposes of the
like kind.
A communication to me from Dr. JOHN W. OVERTON, of Louisville, in the
State of Kentucky, United States of America.
1, 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 Composition of Materials to be used for
Making Blocks for Paving, Cement for Walls, and other purposes of the like
kind.
The improved composition consists of the mineral substance well known as
menaccanite or ilmenite, an oxide of iron and titanium found abundantly in the
American continent and elsewhere, the said substance being combined with asphalte
or bitumen (with the addition preferably of a small quantity of coal tar) and sand,
ashes, or pulverized stone or other suitable mineral substance.
The proportions of these materials may be varied more or less. The following
is a suitable mixture for making paving blocks:
About two-fifths, by weight, of pulverized menaccanite or ilmenite,
About two-fifths, by weight, of sand, ashes, or other suitable pulverized mineral
substance, and
About one-fifth of asphalte or bitumen (including a small quantity of coal tar,
if used).
The first mentioned ingredients described are crushed or otherwise reduced to a
fine state and are then thoroughly mixed with the melted asphalte or bitumen, and
the mixture is then compressed into blocks of a size and shape suitable for paving,
or for building or the like purposes. For this purpose machinery of any of the
ordinary well known kinds may be used.
When cold the blocks so formed are extremely hard, durable, and are capable
of resisting a large amount of wear, whilst not being injuriously affected by acids
or alkalis, they are well suited for paving or for the floors of stables, farm buildings,
and the like.
By increasing the proportion of coal tar used, the mixture may be conveniently
used as a cement for coating walls, floors, and other parts of buildings.
The materials used are inexpensive, the menaccanite or ilmenite being obtainable
in almost any quantity and at little cost.
The precise details respecting the materials used and their proportions may be
varied more or less to suit different circumstances.
Dated this 29th day of June 1893.

An Improved Composition of Materials to be used for Making
Blocks for Paving, Cement for Walls, and other purposes of the
like kind.
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, in the County of Middlesex, do hereby
declare the nature of this invention and in what manner the saine 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 Composition of Materials to be used
for Making Blocks for Paving, Cement for Walls, and other purposes of the like
kind.
The improved composition consists of titanic ores or mineral compounds such as
the mineral substance well known as menaccanite or ilmenite, oxides of iron and
titanium found abundantly in the American continent and elsewhere, the said
substance being combined with asphalte or bitumen (with the addition preferably
of a small quantity of coal tar say about five per cent.) and sand, ashes, or pulverized
stone or other suitable mineral substance.
The proportions of these materials may be varied more or less. The following
is a suitable mixture for making paving blocks:
About two-fifths, by weight, of pulverized menaccanite or ilmenite,
About two-fifths, by weight of sand, ashes, or other suitable pulverized mineral
substance, and
About one-fifth of asphalte or bitumen (including a small quantity about five
per cent. of coal tar if used).
The first mentioned ingredients described are crushed or otherwise reduced to a
fine state and are then thoroughly mixed with the melted asphalte or bitumen, and
the mixture is then compressed (preferably whilst hot) into blocks of a size and
shape suitable for paving, or for building or the like purposes. For this purpose
machinery of any of the ordinary well known kinds may be used.
When cold the blocks so formed are extremely hard, durable, and are capable of
resisting a large amount of wear, whilst not being injuriously affected by acids or
alkalis, they are well suited for paving or for the floors of stables, farm buildings,
and the like.
By increasing the proportion of coal tar used, the mixture may be conveniently
used as a cement for coating walls, floors, and other parts of buildings, or other
like purposes..
The materials used are inexpensive, titanic ores such as the menaccanite or
ilmenite being obtainable in almost any quantity and at little cost.
The precise details respecting the materials used and their proportions may be
varied more or less to suit different circumstances.
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 :-
The preparation of titanic ores or mineral compounds with other substances and
its application substantially in the manner and for the purposes set forth.
