PROVISIONAL SPECIFICATION.
Improvements in Continuous Firing Kilns.
I, JOSEPH HIGSON of Daubhill Brick Works, Daubhil!, Bolton in the County of
Lancaster, Brick Manufacturer, do hereby declare the nature of my said invention to
be as follows:-
This invention relates to improvements in continuous firing kilns and has for its
object to improve the construction and increase the efficiency of the same. This I
effect in the following manner :-The kilns are placed in tiers and fired on alternate
sides each being coupled by flues to convey the heat and flame from one to the other
in successive order so as to produce an uniform heat and obtain the best results with
a minimum of waste. Each kiln is connected by a flue to a main flue leading to a
chimney or chimneys placed in any suitable or convenient position. Dampers are
provided in the said Alues to allow of the heat or flame being shut off from any
one of the said kilns for the purpose of allowing of the same being emptied or filled.

Improvements in Continuous Firing Kilns.
I, JOSEPH HIGSON of Daubhill Brick Works, Daubhill, Bolton in the County of
Lancaster, Brick Manufacturer, do hereby declare the nature of my said 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 improvements in continuous firing kilns and has for its
object to improve the construction and increase the efficiency of the same. This I
effect in the following manner-The kilns are placed in tiers that is side by side and
fired on alternate sides each being coupled by flues to convey the heat and flame
from one to the other in successive order so as to produce an uniform heat and obtain
the best results with a minimum of waste. Each kiln is connected by a flue to a main
flue leading to a chimney or chimneys placed in any suitable or convenient position.
Dampers are provided in the said flues to allow of the heat or flame being shut off
from any one of the said kilns for the purpose of allowing of the same being emptied.
or filled.
DESCRIPTION OF DRAWINGS.

page_text: Fig. 4 a sectional elevation of tubes located in the crown or top covering of each
kiln, and
Fig. 5 a plan of Fig. 4.
The kilns A are placed in tiers-that is, side by side and fired on alternate sides
in successive order as shown, each kiln A being coupled by the flues C to convoy the
heat and flame from one kiln to the other in successive order-back and front and
vice-rersa so as to produce an uniform heat and obtain the best results with a
minimum of waste. Each kiln A is provided with the outlet or down draught B and
the flue E connected to the main flue D leading to the chimney or chimneys F placed
in the position shown or any other convenient position. The flues C, D and E are
provided with the dampers G to allow of the heat or flame being shut off from
any one of the kilns A for the purpose of allowing of the said kilns being emptied,
filled, or repaired as desired. The kilns A are fired at their lower ends or sides-the
length of the fire being only the width of the brickwork in the openings S-and at
the top through the tubes T located in the crown or top covering W of each kiln; the
tubes T being provided with the covers V. The openings S are placed on alternate
sides of the kilns A in successive order as shown in Fig. 1 to allow of alternate firing.
The heat travels through the chamber or kiln A to the passage or down draught B,
then through the flue C to the next chamber; the same being regulated by the
dampers G. A fire is placed in the openings of all the kilns A at work.
This invention is perfect in construction and performs its work in a perfect manner
and contains all the advantages of what are known as the Hoffman and Newcastle
kilns.
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 1
claim is :-
The use, construction, and arrangement of the improvements in continuous firing
kilns, with the passages B, connecting flues C, flues E coupled to the main flues D
leading to the chimneys F, each flue being provided with a damper G to allow of each
kiln being worked separately and also to allow of one or more kilns A being either
emptied or filled while the others are in operation, substantially as described and as
shown in the drawings.
