IMPROVEMENTS IN KILNS FOR BURNING BRICKS AND OTHER ARTICLES."
Year: 1875

page_text: LETTERS PATENT to Joseph Hall, of Woodville, in the County of
Derby, Brickmaker, for the Invention of "IMPROVEMENTS IN KILNS
FOR BURNING BRICKS AND OTHER ARTICLES."
PROVISIONAL SPECIFICATION left by the said Joseph. Hall at the
Office of the Commissioners of Patents, with his Petition, on the
25th September 1875.
I, JOSEPH HALL, of Woodville, in the County of Derby, Brickmaker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
KILES FOR BURNING BRICKS AND OTHER ARTICLES," to be as follows :-
-
This Invention has for its object improvements in kilns for burning
bricks and other articles.
I form each kiln with a series of fire-holes arranged at equal distances
apart all along one side, and on the opposite side I provide a corre-
sponding series of chimneys, and heated gases can pass from the fires
across the kiln amongst the goods to he burnt and so to the chimneys.

page_text: I construct several such kilns side by side, and I provide underground
flues connecting the kilns together. The flues pass out from one kiln in
the spaces between the chimneys, and enter the other kiln in the spaces
between the fire-holes. Both the chimneys and the flues are fitted with
dampers, and when I wish the heat from one kiln to pass into another,
I close the chimney dampers of the first kiln and open the dampers in
the connecting flues. In this way the heat may when desired be caused
to pass through several kilns in succession.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Hall in the Great Seal Patent Office on
the 25th March 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Joseph
HALL, of Woodville, in the County of Derby, Brickmaker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Joseph Hall, Her special
license that I, the said Joseph Hall, my executors, administrators,
and assigns, or such others as I, the said Joseph Hall, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN KILNS FOR BURNING BRICKS AND OTHER ARTICLES," upon the condition
(amongst others) that I, the said Joseph Hall, my executors or ad-
ministrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal

page_text: Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
⚫ NOW KNOW YE, that I, the said Joseph Hall, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:-
This Invention has for its object improvements in kilns for burning
bricks and other articles.
I form each kiln with a series of fire-holes, arranged at equal distances
apart all along one side, and on the opposite side I provide a corre-
sponding series of chimneys, and the heated gases can pass from the
fires across the kiln amongst the goods to be burnt, and so to the
chimneys. I construct several such kilns side by side, and I provide
underground flues connecting the kilns together. The flues pass out
from one kiln in the spaces between the chimneys, and enter the other
kiln in the spaces between the fire-holes. Both the chimneys and the
flues are fitted with dampers, and when I wish the heat from one kiln to
pass into another I close the chimney dampers of the first kiln and open
the dampers in the connecting flues. In this way the heat may when
desired be caused to pass through several kilns in succession.
I build up protection walls within the kilns to prevent the heat from
the fires or from the connecting flues from impinging too directly upon
the goods.
In order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings
hereunto annexed.

page_text: give access to the chimney e, or when the dampers are closed the heated
products from one kiln can pass on to the next by the connecting
flues ff. There are also other flues g, g, running along the ends of the
kilns by which the heated products can be led past an intermediate kiln
when desired; h, h, are the connections between the end flues and the
kilns, they are provided with dampers; i, i, are the doorways, and k, k,
the temporary bottom of open brickwork on which the goods are
stacked.
