IMPROVEMENTS IN KILNS AND STOVES
Year: 1857

page_text: LETTERS PATENT to William Hartley King, of Netherend, near Stour-
bridge, in the County of Worcester, Manufacturer, for the Invention of
"IMPROVEMENTS IN KILNS AND STOVES."
Sealed the 3rd November 1857, and dated the 15th May 1857.
PROVISIONAL SPECIFICATION left by the said William Hartley King
at the Office of the Commissioners of Patents, with his Petition, on the
15th May 1857.
I, WILLIAM HARTLEY KING, of Netherend, near Stourbridge, in the
County of Worcester, Manufacturer, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN KILNS AND STOVES," to be as follows:-
My said Invention consists of the construction and combination of kilns and
stoves, herein-after described. The kilns are made by preference circular,
and with an interior wall rising nearly to the top of the kiln. The fire and
heated air rise from the fireplaces at the bottom between the two walls and
enter the kiln at the top; the heated air converges to the middle of the kiln,
and passes down the same and out at a central opening at the bottom; the
heated air next passes along an underground flue into a flue or channel on or
near the level of the ground and extending along the stove. The heated air
is allowed to pass from the last-mentioned flue into the stove by means of
adjustable dampers or valves. Fireplaces may be situated at intervals in the
last-named flue, so as to increase when necessary the heat of the stove. The

page_text: said fireplaces may be securely closed when not in use. Any desired number of
kilns may be combined in the way described with the stove, so that the surplus
heat of one kiln may be conveyed to the stove when another kiln is not at
work. By means of dampers on the tops of the kilns, the heated air of one
kiln may be made to pass through another kiln before entering the stove, and 5
the heat be thereby moderated. The heated air may also be made to pass
from one kiln to another not lighted, so as to effect the gradual drying and
heating thereof before the lighting of its fire.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Hartley King in the Great Seal Patent Office on
the 13th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HARTLEY KING, of Netherend, near Stourbridge, in the County of Stafford
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of May, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Hartley King, Her special licence that I, the said William Hartley
King, my executors, administrators, and assigns, or such others as I, the said
William Hartley King, 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 AND STOVES," upon the condition (amongst others) that I, the said
William Hartley King, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Hartley King, 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 :-

page_text: My said Invention consists of the method of constructing and combining
kilns and stoves, herein-after described, and illustrated in the accompanying
Drawing. The kilns are made by preference circular, and with an interior
wall rising nearly to the top of the kiln. The fire and beated air rise from
the fireplaces at the bottom of the kiln between the two walls and enter the
kiln at the top; the heated air converges to the middle of the kiln, and passes
down the same and out at a central opening at the bottom; the heated air
next passes along an underground flue into a flue or channel on or near the
level of the ground and extending along the stove. The heated air is allowed
to pass from the last-mentioned flue into the stoves by means of adjustable
dampers or valves. Fireplaces may be situated at intervals in the last-named
flue, so as to increase when necessary the heat of the stove. The said fire-
places may be securely closed when not in use. Any desired number of kilns
may be combined in the way described with the stove, so that the surplus heat
of one kiln may be conveyed to the stove when another kiln is not in work.
By means of dampers on the tops of the kilns, the heated air of one kiln may
be made to pass through another kiln before entering the stove, and the heat
be thereby moderated. The heated air may also be made to pass from one
kiln to another not lighted, so as to effect the gradual drying and heating
thereof before the lighting of its fire.
Figure 1 of the accompanying Drawing represents, in vertical and longi-
tudinal section, part of a stove with flues attached, according to my Invention,
for the purpose of working the said flue in connection with a kiln, or in the
ordinary way, with fire bars, as shewn in the vertical and transverse section of
the same in Figure 2; Figure 3 represents, in end elevation, a stove having
flues made according to my Invention, the flues connecting the stove with
the kiln being marked a; b are the dampers to regulate the heat, which said
dampers are placed at each hole along the range of stoving. Figure 4 is a
ground plan of a kiln with flues attached; Figure 5 is a vertical section of a
kiln, in which the direction of the current of heated air is indicated by the
arrows; the said heated air first rising between the double walls c, d, passing
down through the body of the kiln and out at the bottom along the flue a to
the stove.
By closing the dampers 6 the direction of the current of heated air may be
changed if required, the said current being sent for the purpose of drying
either of the other kilns through the flue e and out at the top f. Either of
the kilns can be used for the discharge of the superfluous heat. The commu-
nication between the kilns may be shut off by the dampers g.
Having now described the nature of my Invention, and the manner of

page_text: carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described, as the same may be varied
without departing from the nature of my Invention; but I claim as my Inven-
tion the improved construction of kilns and stoves, and the method of com-
bining the said kilns and stoves with one another, herein-before described, and
illustrated in the accompanying Drawing.
In witness whereof, I, the said William Hartley King, have hereunto
sét mý hand and seal, this Twelfth day of November, in the year, of
our Lord One thousand eight hundred and fifty-seven.
Witness,
GEORGE SHAW.
WILLIAM HARTLEY KING. (L.S.)
