PROVISIONAL SPECIFICATION.
Improvements in and relating to Fire-bricks, Crucibles, and like
Articles.
We, GEORGE KYNOCH AND COMPANY LIMITED, and EDWARD JONES, Manufacturers,
and WILLIAM EAST, Foreman Bricklayer, all of Lion Works, Witton, in the
County of Warwick, do hereby declare the nature of this invention to be
as follows:-
This invention consists of improvements in fire-bricks, crucibles, and like articles,
and in the manufacture of the same.
The object of our invention is to utilize peat in conjunction with fire clay for the
production of fire-bricks, crucibles, and other fire-resisting articles, having a smooth
surface and sufficient porosity to permit of the ready transmission of heat.
In carrying our invention into effect we add to the fire clay when in a plastic
condition a quantity of peat and thoroughly mix the two substances in a pug mill, a
kneading machine, or in any ordinary and convenient manner. We then mould the
material into bricks crucibles, or other fire-resisting articles of the required form,
which are prepared for use by the drying and burning processes.
During the burning process the peat is consumed or decomposed, thus leaving the
bricks in a porous condition favourable to the transmission of heat. On removal from
the kiln or oven, the bricks or other articles present a smooth and regular surface, and
are adapted for use in furnaces, stoves, or for other required services.
To facilitate the burning or decomposition of the peat we sometimes add coke dust
or other fuel with the plastic fire clay and the peat during the mixing process herein-
before described.
