Year: 1881

page_text: LETTERS PATENT to Richard Ballard, of No. 2, Clifford's Inn, in the City of
London, Solicitor, for an Invention of "A COMBINATION OF A KILN OR OVEN
AND A BOILER FOR GENERATING STEAM OR HEATING WATER."
PROVISIONAL SPECIFICATION left by the said Richard Ballard at the Office
of the Commissioners of Patents on the 21st March 1881.
RICHARD BALLARD, of No. 2, Clifford's Inn, in the City of London, Solicitor.
"A COMBINATION OF A KILN OR OVEN AND A BOILER FOR GENERATING STEAM
OR HEATING WATER."
The object of this Invention is to utilize for the purposes of heating water or
generating steam the heat of the burning substances and fuel in any kiln or oven
capable of being adapted to the Invention, such for instance as a lime kiln, cement
kiin, and kilns or ovens used in the manufacture of pottery and other manufactures
(and both of which words or expressions kiln and oven I hereinafter include and
refer to in the word kiln); by constructing the kiln or partly constructing the kiln
of a plate or plates of iron or steel, or other suitable metal which I call the inner
shell of the kiln; this inner shell of the kiln is surrounded on the outside by a
plate or plates of iron or steel or other suitable metal (which I call the outer shell
of the kiln) at a sufficient distance from the inner shell of the kiln to admit of the
space between them being filled with a sufficient quantity of water. The ends of
the inner shell of the kiln and the ends of the outer shell of the kiln are joined or
rivetted together or connected with a plate or plates, and stayed and made water-
tight in the same manner as an ordinary steam boiler. The outer shell of the
kiln and inner shell of the kiln when joined together in conjunction I call the
boiler.
The heat of the burning fuel and burning substances in the kiln will heat the
water in the boiler and generate steam, or if preferred heat the water, which can be
passed away in pipes for heating purposes, or into a separate boiler to be converted
into steam. The steam can be passed away from the boiler in the same manner as
from an ordinary steam boiler.

page_text: The kiln can be constructed of any shape or pattern and with any arrangements
for regulating the draft or for the feeding with fuel, or for the feeding or drawing
of the products treated required for the purposes of the kiln, and the kiln can be
constructed wholly of the boiler; or if preferred the kiln can be constructed partly
of the boiler and partly of any of the materials at present used in the construction
of kilns; for instance, the sides or parts of the sides of the kiln can be constructed
of the boiler, or the dome or part of the dome of the kiln where a dome is used can
be constructed of the boiler.
The surface or any part or parts of the surface of the plates of the inner shell of
the kiln exposed to the action of the fire can if required be protected from the
action of the fire by a coating of firebricks or other suitable substance.
The boiler can be fitted with the necessary and suitable pipes, valves, and other
necessary fittings and appliances employed in boilers for regulating the supply of
water and steam and other purposes.
I claim as new the combination of a kiln and boiler for generating steam or
heating water.

the inner shell of the kiln and the ends of the outer shell of the kiln are joined or

dome is used, can be constructed of the boiler or the opening or openings or flue or
flues of the kiln, or any part or parts of them respectively can be constructed of
the boiler.
The surface or any part or parts of the surface of the plates of the inner shell of
the kiln exposed to the action of the fire can if required be protected from the
action of the fire by a coating of firebricks or other suitable substance.
The boiler can be of any shape or pattern convenient and can be fitted with the
necessary and suitable pipes, valves, and other necessary fittings and appliances
employed in boilers for regulating the supply of water and steam and other
purposes.
I claim as new the combination of a kiln and boiler for generating steam or
heating water.
In witness whereof, I, the said Richard Ballard, have hereunto set my hand
