Manufacturer do hereby declare the nature of this invention to be as follows:-
In drying stoves or chambers such as are commonly employed for drying bricks
clay ware and other goods, the floors are formed by covers or slabs laid over a series
of flues such covers being commonly made of fire clay and where steam is used as a
source of heat they are made of iron, or of clay glazed on the underside, in order to
prevent permeation of the porous bricks by the steam employed in heating the
chambers. While penetration of the covers may be avoided by this means the
steam readily condenses in the sides and bottoms of the flues and it further passes
through crevices left between the edges of the covers. To obviate the soaking of
the floors by the water of condensation and to avoid the consequent loss of heat
I form floors for drying stoves or chambers from hollow bricks or blocks which are
glazed inside or both inside and outside and are so fitted together as to form a
series of parallel flues for conveying the steam or hot gases which serve to heat the
chambers.
The hollow bricks or blocks may be of any suitable shape and size, but are by
preference rectangular in cross section and may be formed so as to fit into each
other so that they may be jointed together with cement or luting. They may be
made of fireclay or ordinary clay or of any mixture of clay and other matters used
in making clay goods, a cheap glaze or enamel being applied as above mentioned for
the purpose of preventing penetration through the blocks of the steam used as the
source of heat.
I also form in the same manner from hollow bricks or slabs, which are similarly
glazed, shelves or stands upon which clay ware or other goods may be placed to be
dried by the heat of steam or hot gases passing through the flues formed in the
shelves or stands.

I, JOHN HOWIE of Hurlford Fire Olay Works, Kilmarnock, Ayrshire, Fire Clay
Manufacturer 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 :-
In drying stoves or chambers such as are commonly employed for drying bricks,
clay ware, and other goods, the floors are formed by covers or slabs laid over a
series of flues such covers being commonly made of fire clay and where steam is
used as a source of heat they are made of iron or of clay glazed on the under side
in order to prevent permeation of the porous bricks, by the steam employed in
heating the chambers. While penetration of the covers may be avoided by this
means the steam readily condenses in the sides and bottoms of the flues and it
further passes through crevices left between the edges of the covers. To obviate
the soaking of the floors by the water of condensation and to avoid the consequent
loss of heat I form floors for drying stoves or chambers from hollow bricks or
blocks which are glazed inside, or both inside and outside and are so fitted together
as to form a series of parallel flues for conveying the steam or hot gases which
serve to heat the chambers.
The hollow bricks or blocks may be of any suitable shape and size, but are by
preference as shown by the perspective view figure 1, of the annexed diagrams
made rectangular in cross section and they may be formed so as to fit into each
other, or as indicated in figure 2, formed with grooves so that they may be
closely jointed together with cement or luting. They may be made of fireclay
or ordinary clay or of any mixture of clay and other matters used in making
clay goods, a cheap glaze or enamel being applied as above mentioned for the
purpose of preventing penetration through the blocks of the steam used as the
source of heat.
I also form in the same manner from hollow bricks or slabs which are similarly
glazed shelves or stands upon which clay ware or other goods may be placed to be
dried by the heat of steam or hot gases passing through the flues formed in the
shelves or stands.
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. In chambers for drying bricks, clay ware and other goods a floor com-
posed of hollow bricks or slabs glazed internally, or both internally and externally

page_text: and so fitted together as to form a series of flues, substantially as hereinbefore
described.
2. In chambers for drying bricks, clay ware and other goods, a shelf or stand
composed of hollow bricks or slaba glazed internally or both internally and
externally and so fitted together as to form a series of flues, substantially as
herein before described,
