IMPROVEMENTS IN THE CONSTRUCTION OF KILNS FOR BURNING BRICKS, TILES OR OTHER SIMILAR ARTICLES
Year: 1884

page_text: I JACOB DAVIES of 6. Gaskell Street Clifton, near Manchester, Brick Burner
do hereby declare the nature of the said Invention for IMPROVEMENTS IN THE
CONSTRUCTION OF KILNS FOR BURNING BRICKS, TILES OR OTHER SIMILAR
ARTICLES to be as follows:-
My Invention consists of additions to a former Invention for which Letters
Patent bearing date the Seventh day of June in the year 1882 and numbered. 2662
have been granted to me. In the Specification of the said former Invention
I described a square kiln having fire holes only on one side and having air passages
formed below the furnace flue and communicating therewith by means of numerous
air openings. Since the filing of my former Specification I have found the use of
the said air passages to be attended with very great advantage and that the form
of the kiln and method of working the same may be greatly varied so long as the
said air passages are retained.
According to my present Invention I make the kiln of any suitable form, and,
form fire openings on both sides. I also apply the said air passages to kilns which
are formed or worked with upcast flues leading from the furnace dues to the crown
and with intermediate downcast flues communicating with the bottom flues leading
to the chimney and I also apply the said air passages to kilns which are arranged
to work upon the continuous principle and to kilns otherwise arranged the air
passages in all cases supplying air through openings formed in the bottom of the
furnace flue at intervals in the length of the same.

do hereby declare the nature of my 'said. Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF KILNS FOR BURNING BRICKS TILES OR OTHER SIMILAR
ARTICLES," and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement (and accompanying
Drawings) that is to say :-
My Invention consists of additions to a former Invention for, which Letters
Patent bearing date the Seventh day of June in the year 1882 and numbered 2662
have been granted to me. In the Specification of the said former Invention I
described a square kiln having fire holes only on one side and having air passages
formed below the furnace flue and communicating therewith by means of numerous
air openings. According to my present Invention I make the kiln of any suitable
form and form fire openings on both sides.
And in order that my said Invention may be properly understood I will now
proceed more particularly to describe the same reference being had to the annexed
Sheet of Drawings and to the letters and Figures marked thereon.
Fig. 1. of the said Drawings is a vertical cross section of a square kiln constructed
in accordance with my improvements while Fig. 2 is a vertical section of the furnace
flue taken at right angles to Fig. 1. As will be seen from Fig. 1 a fire hole a is
constructed at each side of the kiln through which the fuel is introduced and
spread over the bottom of the furnace flue b. The mouths of the said fire holes
are or may be closed by means of doors not shewn in the Drawing or they might
be bricked up when the kiln is in operation. As in the case of my said former
Invention air to support combustion is introduced through the passage c, which is
covered in by bricks d laid across the top as more clearly seen at Fig. 2. Small
spaces are left between the bricks so as to allow the air to reach the super-imposed
fuel. The amount of air admitted to the passage c may be regulated in accordance
with the degree of heat required in the kiln or it may be entirely shut off. The
bricks to be burnt are stacked in the kiln in the manner shewn in the Drawings
the furnace flues 6 being formed in the course of stacking as usual. It will be
understood that a kiln constructed. with my improvements may contain any
suitable number of the hereinbefore described fire holes with corresponding furnace
flues and air passages. The form and construction of the kiln may also be varied as
my improvements are applicable to kilns having up cast flues leading from the
furnace flue to the crown and with intermediate downcast flues communicating
with bottom flues leading to the chimney. The herein before referred to air
passages are also applicable to kilns which are arranged to work upon the
continuous principle and to kilns otherwise arranged the air passages in all cases
supplying air through openings formed at intervals in the bottom of the furnace
flue substantially, as described and shewn.
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. The construction of brick kilns with fire openings on both sides of the kiln
in combination with air passages formed beneath and communicating with the
furnace flues substantially as hereinbefore described and shewn,

page_text: 2. The application to brick kilns other than those of the square form of air
passages communicating with the furnace flues substantially as hereinbefore
described.
