PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Bricks, Tiles, and other like
Articles.
We AUGUSTE VICTOR BOUVIER and JULES BILLORÉ, both of 1 Boulevard St.
Denis, Paris, France; Manufacturers, do hereby declare the nature of this invention
to be as follows :-
The object of our invention is a novel manufacture of bricks, tiles, or other like
articles, solid or hollow, without baking or burning. With this object we proceed as
follows:-
:-
We make a composition or mixture of friable earths, sand, reduced pebbles or ashes,
and of cement, plaster or lime in the proportion of about 75 parts of the former to 25 parts
of the latter, and we incorporate these ingredients by means of any suitable apparatus
in an acidulated liquid formed of about 80 parts of water and 20 parts of sulphuric
acid. We then add a solution composed of about 80 parts of water to 20 parts of
any suitable hardening substance, such, for instance as subacetate of lead, sulphate of
baryta or sulphate of iron, according to the hardness desired in the bricks or other
articles to be manufactured. For very hard bricks we use the subacetate of lead,
for bricks of less hardness sulphate of baryta, and for bricks of still less hardness
sulphate of iron. The moulding of the bricks or other articles is effected by any
ordinary means after the hardening solution has been added, and 3 or 4 hours are
then required for the hardening to take place. The moulded and hardened products
can then be colored by immersing them for about ten minutes in a solution con-
taining about 20 parts of ochre (grey, yellow, or red), 1 part of sulphuric acid, and 79
parts of water. After the coloring the bricks or articles are allowed to dry and they
are then ready for use. The articles thus manufactured are very cheap and hard, and
resisting.
When it is required to make them waterproof or damp-proof we coat them with
a mixture of sulphur and caoutchouc, dissolved to concentration in a suitable spirit
or essence in the proportions of about 5 parts of sulphur to 95 of caoutchouc, or
we add to the mixture of which the bricks or articles are made about 10 per cent.
of Trinidad pitch or other pitch in the hard state which we melt by means of a
steam jet introduced at the side of the mixing apparatus.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Bricks, Tiles, and other like
Articles.
We AUGUSTE VICTOR BOUVIER and JULES BILLORE both of 1 Boulevard St. Denis
Paris, France, Manufacturers, 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:—
The object of our invention is a novel manufacture of bricks, tiles or other like
articles, solid or hollow, without baking or burning. With this object we proceed as
follows:-
We make a composition or mixture of friable earths, sand, reduced pebbles or
ashes, and of cement, plaster, or lime in the proportion of about 75 parts of the former
to 25 parts of the latter and we incorporate these ingredients by means of any
suitable apparatus in an acidulated liquid formed of about 80 parts of water and

page_text: 20 parts of sulphuric acid. We then add a solution composed of about 80 parts of water
to 20 parts of any suitable hardening substance, such for instance as sub-acetate of
lead, sulphate of baryta, or sulphate of iron, according to the hardness desired in
the bricks or other articles to be manufactured. For very hard bricks we use the sub-
acetate of lead, for bricks of less hardness sulphate of baryta. and for bricks of still
less hardness sulphate of iron. The moulding of the bricks or other articlos is
effected by any ordinary means after the hardening solution has been added, and three
or four hours are then required for the hardening to take place. The moulded and
hardened products can then be colored by immersing them for about ten minutes in
a solution containing about 20 parts of ochre (grey. yellow or red), one part of
sulphuric acid and 79 parts of water. After the coloring the bricks or articles are
allowed to dry and they are then ready for use. The articles thus manufactured are
very cheap and hard and resisting.
When it is required to make them water-proof or damp proof we coat them with
a mixture of sulphur and caoutchouc dissolved to concentration in a suitable spirit
or essence in the proportions of about five parts of sulphur to 95 of caoutchouc, or
we add to the mixture of which the bricks or articles are made about 10 per cent.
of Trinidad pitch or other pitch in the hard state which we melt by means of a
steam jet introduced at the side of the mixing apparatus.
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. The manufacture of bricks, tiles or other like articles without baking or burning
by incorporating in an acidulated liquid, friable earths, sands, reduced pebbles or
ashes and cement, plaster or lime in about the proportions specified; then adding a
hardening solution; then moulding the mixture into the bricks or other articles and
allowing them to dry, substantially as set forth.
2. The manufacture of bricks, tiles or other like articles without baking or burning
by incorporating in an acidulated liquid friable earths, sands, reduced pebbles
or ashes, and cement, plaster or lime in about the proportions specified, hardening
the mixture by the addition of a hardening solution, moulding it into the bricks or
other articles and allowing them to dry, and waterproofing them by coating them with
a mixture of sulphur and caoutchouc, substantially as set forth.
3. The manufacture of bricks, tiles or other like articles without baking or burning
by incorporating in an acidulated liquid friable earths, sands, reduced pebbles or
ashes and cement, plaster or lime in about the proportions specified and a per centage
of Trinidad or other pitch, hardening the mixture by the addition of a hardening
solution, moulding it into the bricks or other articles and allowing them to dry,
substantially as set forth.
4. The manufacture of bricks, tiles or other like articles as set forth.
