PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Terra Cotta and Earthenware
Goods.
PETER TICKLE, Parkmount, Cowley Hill Lane, St. Helens, Contractor &
Builder and Brick & Tile Maker, do hereby declare the nature of this invention
to be as follows:-
To ensure the burning quite through of clay or terra cotta goods, such as bricks,
tiles, pipes or any other articles that require burning in kilns:-By mixing
with the materials a certain portion of ground or very fine riddlings of coal, slack
or cannel, thereby ensureing that each article is thoroughly burnt hard through
without it being defaced and at the same time saving twenty five per cent. of time
labour, burning, waste and cost of fuel, as a kiln burning now 100,000 bricks would
be able to burn 130,000 with less labour.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Terra Cotta and Earthenware
Goods.
I, PETER TICKLE, of Parkmount, Cowley Hill Lane, St. Helens, Contractor and
Building and Brick and Tile Maker, 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:
-
This invention relates to the manufacture of bricks and terra cotta and earthen-
ware goods generally.
The great object in brick-making is to attain sufficient heat to thoroughly burn
the clay with as small a consumption of coal as possible, and with nearly an equal
distribution of heat through the body of the bricks, so that the clay being burnt
quite through, and subjected to the same temperature throughout may contract
equally in bulk, and be one uniform colour.
To ensure this burning quite through of the bricks, I mix with the materials a
certain proportion of ground or very fine riddlings of coal, slack or cannel or
settlings from slack washings. These riddlings are very thoroughly mixed with
the clay, or other materials from which the brick is made, in a pugmill or other-
wise, and when the moulded bricks are placed in the kiln and heat applied, the
riddlings being inflammable generate heat throughout each brick, thus ensuring
937

page_text: that each brick is thoroughly burnt quite through, without being defaced. It is
found also to save a considerable amount of time, labour and fuel, as the bricks
treated by this process do not require nearly so much attention during the process
of burning in the kiln as hitherto. The residue of the burnt or partly burnt
riddlings or settlings remain in the finished article. It is obvious also that this
invention may be applied not only to the manufacture of bricks but also to the
manufacture of terra cotta and earthenware goods generally.
The proportions I propose to use when closed kilns are employed is about a
quarter of a hundred-weight of fine riddlings of coal slack or cannel or settlings
from slack washings to clay sufficient, to make 100 bricks.
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 is:
1. The improvement in the manufacture of bricks and terra cotta and earthen-
ware goods, which consists in mixing with the clay or other materials of which the
bricks or other articles are composed, a certain proportion of ground or very fine
riddlings of coal, slack or cannel or settlings from slack washings and then burning
the said articles in a kiln substantially as and for the purpose described.
2. The manufacture of bricks or terra cotta and carthenware goods containing
ground or very fine riddlings of coal, slack or cannel or settlings from slack
washings substantially as set forth.
