Year: 1879

page_text: LETTERS PATENT to John Foster and Charles James Foster, both of
Normanton, in the County of York, for the Invention of "IMPROVEMENTS
IN KILNS FOR BURNING BRICKS OR OTHER FORMS."
Sealed the 2nd March 1880, and dated the 11th October 1079.
PROVISIONAL SPECIFICATION left by the said John Foster and Charles
Jaines Foster at the Office of the Commissioners of Patents on the 11th
October 1879.
JOHN FOSTER and CHARLES JAMES FOSTER, both of Normanton, in the County
of York. "IMPROVEMENTS IN KILNS FOR BURNING BRICKS OR OTHER FORMY."
Our improvements have reference to kilns consisting of a long parallel arched
chamber, and are for the purpose of burning bricks or other plastic forms better,
also effecting economy in fuel.
"
Instead of applying the "stack or chimney at the end, as is customary in the
above named arched kilns, we bring it nearer the centre or burning part, and arrange
the flue or flues in connection with the kiln and chimney to pass over the furnaces for
the purpose of heating the air in the flue or flues, and thereby causing an increased
draught; and in order to secure a more uniform burning of the bricks or other
plastic forms in the centres and upper parts of the wagons we apply a top flue or
flues. The wagons we employ in these kilns may be of a similar kind to those
described in the Specification of the Letters Paient granted to us bearing date the
We construct the sides of
23rd August 1877, No. 3213, or other convenient form.
the kiln in such a manner as to project over the tops of the wagons, and employ in
combination therewith the side joints for the purpose of excluding the air. The
furnaces are fed with heated air.
The drying chambers are provided with flues, through which the heated air may
be admitted thereto, and thence to the main flue, these flues being provided in the
side walls.
In order to readily supply sand or other material to the joints we employ holes
or openings in connection with the side joint trough, down which the material is
passed.
Suitable dampers are employed for dividing or separating the drying part of the
kiln from the burning part, also for closing the ends from the outer air. Dampers
are also used for the various flues for directing the air.
For partially drying bricks or other forms composed of plastic materials we, by
preference, provide a continuous chamber above the hereinbefore mentioned kiln,
through which small wagons containing bricks or forms are passed; sufficient heat
rises from the kiln for this operation.

JOHN FOSTER and CHARLES JAMES FOSTER, both of Normanton, in the County
of York. "IMPROVEMENTS IN KILNS FOR BURNING BRICKS OR OTHER FORMS."
Our improvements have reference to kilns consisting of a long parallel arched
chamber, and are for the purpose of burning bricks or other plastic forms better,
also effecting economy in fuel.
Instead of applying the "stack" or chimney at the end, as is customary in the
above named arched kilns, we bring it nearer the centre or burning part, and
arrange the flue or flues in connection with the kiln and chimney to pass over the
furnaces for the purpose of heating the air in the flue or flues, and thereby causing
an increased draught; and in order to secure a more uniform burning of the bricks
or other plastic forms in the centres and upper parts of the wagons we apply a top
flue or flues. The wagons we employ in these kilns may be of a similar kind to
those described in the Specification of the Letters Patent granted to us bearing
date the 23rd August 1877, No. 3213, or other convenient form. We construct tho
sides of the kiln in such a manner as to project over the tops of the wagons, and
employ in combination therewith the side joints for the purpose of excluding the
air.
The furnaces are fed with heated air.
The drying chambers are provided with flues, through which the heated air may
be admitted thereto, and thence to the main fluc, these flues being provided in the
side walls.
In order to readily supply sand or other material to the joints we employ holes
or openings in connection with the side joint trough, down which the material
is passed.
Suitable dampers are employed for dividing or separating the drying parts of
the kiln from the burning part, also for closing the ends from the outer air.
Dampers are also used for the various flues for directing the air.
For partially drying bricks and other forms composed of plastic materials we, by
preference, provide a continuous chamber above the herein before mentioned kiln,
through which small wagons containing bricks or forms are passed; sufficient hent
rises from the kiln for this operation.
And in order that our Invention may be more completely understood reference is
given to the accompanying Drawings, and to the letters and marks thereon.

page_text: The wagons i we employ may be of a similar construction to those described in
the Specification of British Letters Patent granted to us bearing date 23rd August
1877, No. 3213, or of any other convenient form.
We construct the sides j of the kiln in such a manner as to project over the tops
of the wagons i, and employ in combination therewith side joints k, which are of
ordinary construction.
The air previous to being passed to the furnaces c is carried underneath the
wagons i, and thence through opening or passage k³ to the fires; by this means the
air becomes heated previous to being supplied to the fires c.
The drying chamber is provided with the flues m, through which the heated
air may be admitted, and thence through openings n into main flues & and d, or
direct from side flues m through opening p into main flue d, d, the size of such
openings being regulated by dampers q, and by such adjustment regulating the
temperature of the drying chamber l.
rands are large dampers or sliding doors which we employ to partition off the
drying part of the kiln from the burning part and from the outer air; t is large
damper or sliding door at other end, the former dampers r and s being for
separating the drying chamber from the outer air and from the kiln proper, the
latter t is the exit door at the other or exit end of kiln; these dampers or sliding
doors may be made sufficiently long to pass down to the floor, or to rest on the
tops of the wagons i, or as substitutes for the tops of the wagons i boarding may
be put across and supported on the side joint troughs k¹.
In order to supply sand or other material to the side joints & we employ holes or
openings v in connection with the side joint troughs & down which the material is
passed.
Fuel is fed, when required, on to the bricks or other forms during the operation
of burning through feed holes w.
Dampers may be employed in the various flues for directing and regulating the
passage of air.
For partially drying bricks and other plastic forms we, when preferred, provide a
continuous chamber above the hereinbefore mentioned kiln, through which small
wagons containing bricks or forins are passed; sufficient heat rises from the kiln
for this operation.
Having now described the nature of our said Invention, what we claim is,―
First. The arrangement, construction, and application of the various flues
arranged in continuous arched kilns, substantially as and for purposes hercin set
forth.
Second. The arrangement and application of large dampers or sliding doors,
substantially as herein set forth.
Third. The combination of the various parts forming the continuous arched kiln,
substantially as and for purposes herein set forth.
In witness whereof, we, the said John Foster and Charles James Foster, have
hereunto set our hands and seals, this Fifth day of April, in the year o.
our Lord Oue thousand eight hundred and eighty.
