Year: 1880

page_text: LETTERS PATENT to Courtenay Kingsford, of Upper Clapton, in the County
of Middlesex, Manufacturing Chemist, for an Invention of "IMPROVEMENTS
IN APPARATUS FOR THE GENERATION OF STEAM, THE MANUFACTURE OF
COKE AND GAS, AND FOR SIMILAR PURPOSES."
PROVISIONAL SPECIFICATION left by the said Courtenay Kingsford at the
Office of the Commissioners of Patents on the 23rd January 1880.
COURTENAY KINGSFORD, of Upper Clapton, in the County of Middlesex,
Manufacturing Chemist. "IMPROVEMENTS IN APPARATUS FOR THE GENERATION
OF STEAM, THE MANUFACTURE OF COKE AND GAS, AND FOR SIMILAR PURPOSES."
My Invention relates to the combination of a furnace, oven, or retort (wherein
coal may be burned for the manufacture of coke and other purposes) with a
chamber or chambers for containing water, and generating steam therefrom to be
used for any purpose for which the latter is ordinarily or may be required.
The said Invention is chiefly designed to afford the means whereby the heat
which escapes from coke-ovens, gas retorts, and the like, and which is now wasted,
may be utilized for the generation of steam, so that in factories, chemical and gas
works, and other places where steam is required, the same will be obtained without
the consumption of fuel, especially for its production.
The saving effected by this system of working will be very great, and my
improved apparatus affords the means for carrying the same into effect in a very
advantageous manner.
The said apparatus is constructed as follows, that is to say:-I form a coke oven
of boiler iron or other suitable metal, preferably with an arched top and flat bottom.
I place this oven inside a casing or shell also formed of boiler plates or other
suitable metal in such a manner that a space is left all around the sides, top, back,
front, and bottom of the apparatus between the oven and the outer casing or jacket.
I support the oven in its proper position within the jacket by suitable stays or
distance pieces; the doorway for filling and emptying the oven is formed through
the inner and outer front plates of the apparatus, and must be surrounded by a
water-tight ring properly secured between the said plates. It will be obvious that
the form and dimensions of the said ovens and their water-chambers may be varied
or modified in any required manner.

page_text: I may also modify the construction of the said apparatus by forming the bottom
of the same without a water space or jacket below it; in this case the water space
or jacket will extend at the sides to, but not beyond, the bottom of the said
apparatus, and the bottom of the retort is formed of fire-clay or other suitable
refractory substance. I may also further modify the said apparatus by forming the
oven entirely or partially of bricks, and surrounding or partially surrounding the
same with metal tubes which form the water-chamber or space.
My Invention also comprises the combination of a water jacket or chamber with
a retort used for the manufacture of gas and for similar purposes.
In this case I
cover the top and sides of the retort with the said water jacket or chamber, and
thereby form a steam generating vessel or series of such vessels which will supply
steam enough for all the purposes of the works in which the same are used.
It will be understood that in all of the forms or modifications in which my
Invention is used the steam-generating chambers may be provided with any
suitable valves and other fittings to regulate or control the pressure, the supply of
water, and the delivery of steam.

COURTENAY KINGSFORD, of Upper Clapton, in the County of Middlesex,.
Manufacturing Chemist. "IMPROVEMENTS IN APPARATUS FOR THE GENERATION
OF STEAM, THE MANUFACTURE OF COKE AND GAS, AND FOR SIMILAR PURPOSES."
My Invention relates to the combination of a furnace, oven, or retort, wherein
coal may be burned for the manufacture of coke and for other purposes, with a
chamber or chambers for containing water, and generating therefrom steam to be
used for any purpose for which the latter is ordinarily or may be required.
The said Invention is chiefly designed to afford the means whereby the beat which
escapes from coke ovens, gas-retorts, and the like, and which is now wasted, may
be utilized for the generation of steam, so that in factories, chemical and gas works,
and other places where steam is required, the same will be obtained without the
consumption of fuel, especially for its production.
The saving effected by this system of working will be very great, and my
improved apparatus affords the means for carrying the same into effect in a very
advantageous manner.
In the accompanying Drawings I have shewn, as examples only of my improve-
ments, various forms of apparatus as I may construct the same for the purpose of
my said Invention.
In these Drawings Figure 1 is a side elevation, and
Figure 2 a transverse section of one form of the said apparatus.
Figure 3 is a longitudinal section, and
Figure 4 an end elevation partly in transverse section of a modification of the
said apparatus.
Figure 5 is a longitudinal section.
Figure 6 an end elevation partly in transverse section, and
Figure 7 a plan partly in horizontal section of another modification of the
same.
Figure 8 is an end elevation partly in section of a further modification hereinafter
explained.
The said apparatus is constructed as follows, that is to say:-I form a coke-
oven a of boiler iron or other suitable metal, preferably with a flat bottom and an
arched top, although if desired it may have a square top. I place this oven inside
a casing or shell b also formed of boiler plates or other suitable metal in such a
manner that a space c is left all around the sides, top, back, and front, and if
desired at the bottom of the apparatus between the oven a and the outer casing or
jacket b. I support the oven a in its proper position within the jacket 6 by suitable
stays or distance-pieces; the doorway for filling and emptying the oven is formed
through the inner and outer front plates of the apparatus, and must be surrounded
by a water-tight ring properly secured between the said plates. It will be obvious
that the forms and dimension of the said ovens and their water-chambers may be
varied or modified in any required manner. Provision for supplying the fuel into
the oven may be made by providing the same with one, two, or more feed-apertures
at the top, sides, or other part of the oven, and rails may be arranged for trucks or
trolleys to bring the fuel to these apertures.
It will be seen that in the examples shewn in Figures 1 to 7 the space or
jacket c extends at the sides to, but not beyond, the bottom of the said apparatus.
The bottom of the retort or oven is formed of fire-clay or other suitable refractory
substance. I may also in some cases line the sides with fire-brick or other suitable
substance. Or I form the sides, bottom, and ends of the oven of fire-brick or other
suitable material, and arrange a dome or covering of boiler-plates, jacketed as shewn
in Figure 8, to provide the necessary steam-space c.

page_text: I may also further modify the said apparatus by forming the oven entirely or
partially of bricks, and surrounding or partially surrounding the same with metal
tubes which form the water chamber or space. In Figure 2 I have shewn an
arrangement of apparatus for injecting water into the steam-generating chamber.
My Invention also comprises the combination of a water jacket or chamber with
a retort used for the manufacture of gas, and for similar purposes. In this case I
cover the top and sides of the retort with the said water jacket or chamber, and
thereby form a steam-generating vessel or series of such vessels, which will supply
steam enough for all the purposes of the works in which the same may be used.
It will be understood that in all the forms of modifications in which my Invention
is used, the steam-generating chambers may be provided with any suitable valves
and other fittings, as shewn in Figure 2, or otherwise, to regulate or control the
pressure, the supply of water, and the delivery of steam.
Having thus fully described my said Invention, and the manner of performing
the same, I wish it understood that I claim, providing means whereby the heat
from a coke-oven, gas-retort, or the like, may be utilized in the manner above
specified for the generation of steam, so that in factories and other places where
steam is required, it may be obtained without the additional cost or the consumption
of fuel burned expressly or especially for its production or generation; also the
employment for this purpose of the apparatus consisting of a coke-oven, gas-retort,
or the like, combined with a steam-generating chamber, as in the examples shewn
in the Drawings, or in any modifications thereof, as above set forth.
In witness whereof, I, the said Courtenay Kingsford, have hereunto set my
hand and seal, this Twenty second day of July, in the year of our Lord
One thousand eight hundred and eighty.
COURTENAY KINGSFORD, (LS.)
