PROVISIONAL SPECIFICATION.
Improvements in or relating to the Floors and Heating Flues of
Drying Houses, Malt Kilns, and other like Structures.
I JOHN HALL of Lansdowne House, Swadlincote in the County of Derby, Colliery
Owner and Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to drying houses, malt kilns, hot houses and other like
structures which are constructed with heating flues or flue pipes under or within their
floors, and my invention consists in a construction in which the flue pipes when laid,
themselves form both flue and floor.
With this object I make rectangular or oblong earthenware blocks or slabs through
each of which is a longitudinal flue or pipe. These blocks, when laid together side by
side and end to end in a similar manner to paving blocks or slabs, not only form the
floor but also constitute a series of flue pipes. The ends of each block are so formed
that the flue or pipe portions can be fitted together with a tight joint in a similar
manner to earthenware pipes, and for this purpose I prefer to construct them with the
well known socket and spigot arrangement. Where cross or transverse flues are
required in the floor those blocks which are to be laid in the line of such flues will be
formed with cross flues or pipes in addition to the longitudinal flues or pipes; and at
the end of a course where one flue is to be connected to another the end of the block
will have its flue in the form of a bend or elbow. Each block may either be formed
in one piece with its flue pipe complete, or it may be formed of two parts, one to fit.
upon the top of the other, and each part being formed with half the pipe or flue. In
this case the two parts of the block, when put together, will have a joint made between
them by means of cement or other suitable material.
In the case of malt kilns or other structures where hot air should escape from the
Alues into the building the flue pipes are formed with perforations at top.
The hot air or other medium for heating the flues may be conveyed thereto by means
of an iron or other pipe led along one end of the floor and connected by branches to
each of the longitudinal flues, the connections being made tight by means of cement.
or other suitable material.

COMPLETE SPECIFICATION.
Improvements in or relating to the Floors and Heating Flues of
Drying Houses, Malt Kilns, and other like Structures.
I, JOHN HALL of Lansdowne House, Swadlincote in the County of Derby, Colliery
Owner and Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention has reference to drying houses, malt kilns, hot houses and other like
structures which are constructed with heating flues or flue pipes under or within their
floors, and my invention consists in a construction in which the flue pipes when laid,
themselves form both flue and floor.
With this object I make rectangular or oblong earthenware blocks or slabs, through
each of which is a longitudinal flue or pipe. These blocks when laid together side by
si le and end to end in a similar manner to paving blocks or slabs not only form the
floor but also constitute a series of flue pipes. The ends of each block are so formed
that the flue or pipe portions can be fitted together with a tight joint in a similar

page_text: manner to earthenware pipes, and for this purpose I prefer to construct them with the
well-known socket and spigot arrangement.
Where cross or transverse flues are
required in the floor those blocks which are to be laid in the line of such flues will be
formed with cross-flues or pipes in addition to the longitudinal flues or pipes; and at
the end of a course where one flue is to be connected to another the end of the block
will have its flue in the form of a bend or elbow. Each block may either be formed
in one piece with its flue pipe complete or it may be formed of two parts, one to fit
upon the top of the other and each part being formed with half the pipe or flue. In
this case the two parts of the block when put together will have a joint made between
them by means of cement or other suitable material.
In the case of malt kilns or other structures where hot air should escape from the
flues into the building the flue pipes are formed with perforations at top.
The hot air or other medium for heating the flues may be conveyed thereto by means
of an iron or other pipe led along one end of the floor and connected by branches to
each of the longitudinal flues, the connections being made tight by means of cement.
or other suitable material.
The accompanying drawings will serve to illustrate my invention. Figure 1 is a
plan or top view of a rectangular or oblong block or slab for use where cross or
transverse flues are required in the floor in which case the block has not only a
longitudinal flue or pipe a but also a cross or transverse flue or pipe b. This block is
shown with the well-known socket and spigot arrangement whereby it is fitted to the
adjoining blocks. c c are the sockets to receive the spigots of the adjoining blocks an:l
dd the spigots to fit into the sockets of the adjoining blocks. Figure 2 is an elevation
of the spigot side of the block shown in Figure 1-Figure 3 an elevation of the
socket side; Figure 4 an elevation of the socket end; Figure an elevation of the
spigot end Figure 6 a section on the line A B of Figure 3; Figure 7 a section on
the line CD of Figure 6 and Figure 8 a section on the line E F of Figure 6.
Figure 9 is a horizontal section showing a block of the form represented in
Figures 1 to 8 with another block with only a longitudinal fluo fitted thereto.
e represents cement or other material for making a tight joint between the socket and
spigot of the adjoining pipes as in ordinary socket and spigot joints. Figures 10, 11
and 12 are horizontal sections representing blocks with flues having bends or elbows
such as will be used at the end of a course. Figure 13 illustrates in plan view and
Figure 14 in section on the line I J of Figure 13 a portion of a floor laid with my
blocks or slabs; those shown have longitudinal flues only. is the pipe for supplying
the flues with hot air or other heating medium; this pipe is laid along one end of the
floor and has branches g g to the longitudinal flues. The connections between the
branches g g and the flues are made tight by cement or other suitable material at h.
Figures 15 and 16 represent my blocks formed in two parts, one to fit upon the top
of the other and each part being formed with half the flue or pipe. When these two
parts are put together as in Figure 15 a joint is made between them by cement or
other material at i.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In the construction of the floors and heating flues of drying houses, malt kilns and
other like structures, the employment of rectangular or oblong earthenware blocks or
slabs with flues or pipes therein and which, when laid, form both the floor and the
heating flues as set forth.
2. Earthenware blocks or slabs so made or formed as to serve both as paving blocks
or slabs and as heating flues, as set forth.
