Improvements in or relating to the Manufacture of Brioks
I, JONATHAN ROWE, of 6, Gray's Inn Place, in the County of Middlesex, Brick
Maker, do hereby declare the nature of this invention to be as follows...
-
Bricks made from 11ver mud or clay as heretofore very frequently shrink or
warp during the drying stage of their manufacture and it is difficult therefore to
ensure that the finished brick will be. of regular shape and size
The object of this invention is to prevent this shrinkage during the drying
stage and thus to ensure a brick of regular conformity.
The chief ingredient of the bucks made in accordance with my invention is
uve mud or clay, but preferably the former, with which I intimately mix a
suitable bye-product such for example as a burnt spent oxide from gas, chemical
and other works, that is an oxide from which sulphur has been extracted for
manufacturing purposes
In manufacture I prefer to pass the river mud or other ingredient and the oxide
through olleis so that they may be granulated and intimately mixed together.
This mixture of mud and oxide then passes into the brick making machinery
and the brick is subsequently dried and finished in the usual manner
If desired sand may be incorporated with the mud and oxide, in which case
the proportion of oxide used will be lessened

Improvements in or relating to the Manufacture of Bricks,
I, JONATHAN ROWE, of 6, Gray's Inn Place, in the County of Middlesex, Brick
Maker, do hereby declare the nature of this invention and in what manner the
same 18 to be performed, to be particularly described and ascertained in and by
the following statement.
1
Bricks made from river mud or clay as heretofore very frequently shrink or
warp during the drying stage of then manufacture, and it is difficult therefore
to ensure that the finished brick will be of regular shape and size The object
of this invention is to prevent this shrinkage during the drying stage and thus
to ensure a brick which is of regular conformity and moreover sounder and
stronger in quality than could be produced without the use of the spent oxide
hereinafter referred to
Bricks made in accordance with this invention are composed of an admixture of

page_text: river mud or of clay, but preferably the former, and a bye-product, burnt spent
oxide from a gas, chemical or other works, that is to say an oxide from which
sulphur has been extracted for manufacturing purposes.
In manufacture I prefer to pass the river mud or other ingredient and the
oxide through 1ollers which granulate and intimately mix them. This mixture
of mud or clay and oxide in which there may very well be about equal parts by
weight of mud or clay and oxide, or more or less of the oxide as may be found
desirable for the production of a brick of given quality, then passes into the
brick-making machinery, and the bucks which issue from it are subsequently
dried and finished in the usual manner
If desued sand may be incorporated with the mud or clay and oxide, in which
case the proportion of oxide used will be lessened
The use of an oxide in minute proportions to merely produce a desired colour in
a brick is well known, and to the use of an oxide for such a purpose I make
no claim, but
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim 18
-
1 In the manufacture of bricks an admixture of river mud or of clay and
spent oxide with or without sand for the purpose described
2 A brick of river mud or of clay and spent oxide with or without sand for
the pui pose described
