Improvements in the Construction and Arrangement of Furnace
Flues for Drying Sheds Employed in the Manufacture of Bricks,
Tiles, Earthenware, and the like.
I, JOSEPH WILDING, of Wave Crest, Brunswick Road, Douglas, Isle of Man,
Manager of Brickworks, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the construction and arrangement of
the furnace flues for drying sheds employed in the manufacture of bricks, tiles,
earthenware, and the like.
Prior to my invention a series of flues have been run longitudinally from one end
of the building down one-side to a chimney at the other end or else returned along
the floor to a chimney at the same end as the furnace.
In like manner the next series of flues run longitudinally through the building
from a furnace placed at the opposite end to the first named, and so on any
convenient number of furnaces and flues may be arranged according to the size of
the shed or building.
A serious drawback and defect in this arrangement -is that owing to the length
of the flues there is a great difference in temperature the heat gradually diminishing
froin the furnace to the chimney.
The chief object fofumy improvements is to overcome this defect and to enable
the temperature to be equalized and rendered more uniform throughout or to be
-regulated and concentrated at certain given parts if desired.
I accomplish this object by building a series of cross flues leading from the
furnace of one set of flues to the flues of the next furnace at a-point-where-the
gases have become comparatively,cool. These cross flues are fitted with butterfly
valves or other suitable valves or dampers by means of which I am able to admit
hot gases into any desired flue or flues. "
I may employ any suitable number of furnaces and flues in combination as
described.

Improvements in the Construction and Arrangement of Furnace
Flues for Drying Sheds' Employed' in the "Manufacture of Bricks,
Tiles, Earthenware, and the like.
1, JOSEPH WILDING," of 'Wave Crest, 'Brunswick Road, Douglas, Isle of Man,
Manager of Brickworks, 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 :-
My invention relates to improvements in the construction and arrangement of
the furnace flues for drying sheds employed in the manufacture of bricks, tiles,
earthenware, and the like.

page_text: Prior to my invention a series of flues have been run longitudinally from one end
of the building down one side to a chimney at the other end or else returned along
the floor to a chimney at the same end as the furnace.
In like manner the next series of flues run longitudinally through the building
from a furnace placed at the opposite end to the first named and so on any
convenient number of furnaces and flues may be arranged according to the size of
the shed or building.
A serious drawback and defect in this arrangement is that owing to the length
of the flues there is a great difference in temperature the heat gradually diminishing
from the furnace to the chimney.
The chief object of my improvements is to overcome this defect and to enable
the temperature to be equalized and rendered more uniformn throughout or to be
regulated and concentrated at certain given parts if desired.
I accomplish this object by building a series of cross flues leading from the
furnace of one set of flues to the flues of the next furnace at a point where the
gases have become comparatively cool.
In the accompanying two sheets of drawings-
Figure 1 is a sectional plan of a drying shed with two furnaces and flues
constructed and arranged according to my improvements. Figure 2 is a side
sectional elevation of part of the same.
Figure 3 is a sectional plan of a drying shed illustrating my improvements as
applied to three furnaces and flues.
In these views, a designates the outside walls of the drying shed which may
be of any suitable size, the inner or dividing walls, c the furnaces, two being
shown in Fig. 1, and three in Fig. 3, but of which there may be any suitable
number in combination, and d the longitudinal flues which are shown running from
end to end of the building and returning to a chimney eat the same end as their
furnace but which instead of returning inay terminate in a chimney at the opposite
end to their furnace it desired.
The above specified parts constitute a well known arrangement of furnaces and
flues and require no further description as their construction and mode of operation
is well understood.
The cross flues which embody my invention, lead as clearly shown in the plan
views, Figs. 1 and 3, from each furnace c under its longitudinal flues d and into the
longitudinal flues d belonging to the other furnace c (Fig. 1) or one of the other
furnaces c (Fig. 3). These cross flues fare fitted with butterfly valves g or other
suitable valves or dampers h by means of which I am able to admit hot gases into
any desired flue or flues and so regulate and equalize the heat of the drying shed.
Fig. 2 shows two hollow pillars or vertical flues in communication with the
furnace flues and provided with external shelves which I show as forming a
convenient arrangement for drying bricks or the like but to which I lay no claim.
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. An arrangement for conducting the gases from one furnace through cross
flues into the longitudinal flues of the next furnace to a point in said longitudinal
flues where the gases from their furnace have become comparatively cool
substantially as herein set forth.
2. The combinations and arrangements of parts embodying my improvements in
the construction of furnace flues for drying sheds substantially as herein described
with reference to the accompanying drawings.
