IMPROVEMENTS IN THE CON- STRUCTION OF KILNS FOR BURNING BRICKS, TILES, OR OTHER SIMILAR ARTICLES
Year: 1882

page_text: LETTERS PATENT to Jacob Davies, of Kearsley Moor, near Manchester, in the
County of Lancaster. for an invention of IMPROVEMENTS IN THE CON-
STRUCTION OF KILNS FOR BURNING BRICKS, TILES, OR OTHER SIMILAR
ARTICLES
PROVISIONAL SPECIFICATION left by the said Jacob Davies at the Office
of the Commissioners of Patents on the 7th June 1882.
JACOB DAVIES of Kearsley Moor near Manchester in the County of Lancaster
"IMPROVEMENTS IN THE CONSTRUCTION OF KILNS FOR BURNING BRICKS, TILES,
OR OTHER SIMILAR ARTICLES
"
The objects of this invention are, to greatly economize the fuel consumed, and to
improve the burning of the bricks or other articles, and prevent them from becoming
broken or discolored.
The invention relates to what are known as square kilns and consists firstly in
building such kilns with fire holes only upon one side of the kiln the opposite side
being made quite plain, or without fire holes.
Inside the ordinary flues I form smaller flues of bricks laid on edge with other
bricks placed transversely upon them, spaces being left between the latter. These
inner flues communicate with air holes left in the blank side of the kiln, so that
the air entering these flues becomes heated before it passes into the main flues, and
thus no cold air comes into contact with the bricks and they are not so liable to
become broken or discolored.
By opening or closing the air holes the amount of air admitted may be regulated
to any desired extent, whereby the formation of smoke will be materially prevented
and a very great economy in the amount of fuel will be effected.

JACOB DAVIES of Kearsley Moor near Manchester in the County of Lancaster
"IMPROVEMENTS IN THE CONSTRUCTION OF KILNS FOR BURNING BRICKS TILES,
OR OTHER SIMILAR ARTICLES
"
The objects of this invention are to greatly economize the fuel consumed to
lessen the space required for a given number of kilns, and to improve the burning
of the bricks or other articles and prevent them from becoming broken or
discolored.
The nature of my said invention will be readily understood on reference to the
drawings annexed hereunto and the following explanation thereof.
Fig. 1. on the drawing is a longitudinal section through one of the flues of a
square kiln constructed according to my invention and Fig. 2 is a transverse
section of the same.
The invention relates to what are known as square kilns and consists first in
building such kilns with fire holes a, a only upon one side of the kiln, the opposite
siḍe b, b being made quite plain or without fire-holes.
Inside the ordinary flues c, c I form smaller flues d, d of bricks laid on edge (or
flat as shown) with other bricks, placed transversely upon them spaces being left
between the latter. These inner Blues d, d communicate with air holes left beneath,
the fire holes a, a and also with other air holes e, e left in the blank side of the
kiln, so that the air entering these flues d, d becomes heated before it passes into
the main flue c, c and thus no cold air comes into contact with the bricks and they
are not so liable to become broken or discolored.
By opening or closing these air holes the amount of air admitted may be
regulated to any desired extent whereby the formation of smoke will be materially
prevented and a very great economy in the amount of fuel will be effected.
ff are feeding holes or openings formed in the back or blank side b, b of the kiln
above the inner flues d, d through which slack or other fuel may be supplied to the
back part of the main flues c, c when required, after which these holes or openings
are bricked up.
Having now described the nature and object of my said Invention together with
the manner in which the same is to be or may be performed or carried into practical
effect I wish it to be understood that I claim as my invention the construction of
Kilns for burning bricks, tiles, or other similar articles substantially as herein-before
set forth and illustrated by the drawings annexed.
In witness whereof the said Jacob Davies has hereunto set his hand and seal
this fourth day of December in the year of our Lord one thousand eight
hundred and eighty two, the same having been first distinctly read over
and fully explained to him who seemed perfectly to understand the same,
and who set his mark thereto in presence of
