I JOHN WILLIAM WAILES of The Cedars Bescot Walsall in the County of
Stafford, Engineer, do hereby declare the nature of this invention to be as.
follows:-
The main objects are to increase efficiency by augmenting blow pipe action of flame,
when air and gas are directed downwards on the hearth or a charge thereon. I dis-
pose the air regenerator at such a distance below the hearth and lead a flue from the
top of the same that the speed of the natural current from the regenerator to the ports
is so increased as to secure the desired effect. The above construction is specially
applicable when the Hackney port is used, and is also applicable to ordinary furnaces
and furnaces with movable hearths. It is particularly desirable when the hearth is
deep, as when used for the basic process.
To improve the construction of open hearth regenerative furnaces and render them
more durable I lower the air regenerators as above setforth, and reduce the area of
the ports in proportion to the increased speed of air current obtained. A further
improvement under this part consists in constructing deep regenerators in sections one
above the other so that the weight of the bricks or materials in any section does not
effect the one below. I provide each section with cleaning doors.
To facilitate repairs I make open hearth regenerative furnaces having Hackney port
with a movable hearth and with fixed or movable roof and flues.
A further improvement to facilitate repairs and secure continuous working consists
in so disposing regenerators and connecting them to the furnaces when there are two
or more furnaces, that one or more of the regenerators may be coupled to either of two
or more adjacent furnaces. A convenient modification under this part of our invention
consists in placing between the regenerators of two hearths a spare pair of regenera-
tors with flues adopted for connection to either hearth.
To obtain proper control over the temperature for economical working, I provide
means either by direct heat, or by the utilization of part of the waste products of
combustion, to impart heat to regenerators before they are connected with a hearth.

I, JOHN WILLIAM WAILES of The Cedars Bescot Walsall in the County of Stafford,
Engineer do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
The main objects are to increase the efficiency of open hearth regenerative furnaces
for the production of steel, to improve their construction, to facilitate repairs, and to
obtain proper control of temperature for economical working.
For the purpose of increasing efficiency by augmenting blow pipe action of flame,
when air and gas are directed downwards on the hearth or the charge thereon I dispose
the air regenerators at such a distance below the hearth and lead flues from the tops of
the same to the furnaces that the speed of the natural current from the regenerators to
the ports is so increased as to secure the desired effect. The above construction is
specially applicable when the Hackney port is used, and is also applicable to ordinary
furnaces and furnaces with movable hearths. It is particularly desirable when the
hearth is deep as when used for the basic process.
To improve the construction of open hearth regenerative furnaces and render them
more durable I lower the air regenerators as above setforth, and reduce the area of
the ports in proportion to the increased speed of air current obtained. A further
improvement under this part consists in constructing deep regenerators in sections one
above the other so that the weight of the bricks or materials in any section does not
effect the one below. I provide each section with cleaning doors.
To facilitate repairs I make open hearth regenerative furnaces having Hackney ports
with a movable hearth and with fixed or movable roof and flues.
A further improvement to facilitate repairs and secure continuous working consists
in so disposing regenerators and connecting them to the furnaces when there are two
or more furnaces, that one or more of the regenerators may be coupled to either or
any one of two or more adjacent furnaces. A convenient modification under this part
of our invention consists in placing between the regenerators of two hearths a spare
pair of regenerators with flues adapted for connection to either hearth.
To obtain proper control over the temperature for economical working I provide
means either by direct heat, or by the utilization of part of the waste products of
combustion, to impart heat to regenerators before they are connected with a hearth.

furnaces. gas regenerators. e flues leading from the gas regenerators to the
furnaces.
Regenerators under my invention are made in sections one above another and
separated one from the other by arches g on which the bricks or materials for retaining
heat rest. h are doors to allow access to each section for cleaning or other purposes.
To allow of the gases for heating or to be heated to pass from section to section the
arches
gare perforated or gas ways are made from section to section.
The furnace hearths are carried in a frame on wheels, and are movable on the
lines j. Between two furnaces there are three air regenerators and three gas regenera-
tors. The central air regenerator and central gas regenerator d are connected to the
side regenerators by flues and valves are provided by means of which the central or
side regenerators may be shut off or connected to the furnaces through the flues c or e.
m smoke flue. n gas flue.
o air flue. valves for connecting or shutting off the
regenerators from the smoke gas and air, according as it is desired to pass gas and air
through the heated regenerators or the products of combustion through the regenera-
tors to be heated.
To heat the regenerators before use the products of combustion from a furnace
or special fire place are sent through the regenerators by means of connecting flues
direct to the regenerators or to the air and gas flues.
My improved movable hearth furnaces with Hackney ports may be provided with
movable roofs & flues as in existing furnaces.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what. I claim is:
First. In furnaces in which the air and gas are directed downwards on the hearth
disposing air regenerators and connecting them to the furnaces substantially in the
manner and for the purposes setforth.
Second. In open hearth regenerative furnaces constructing regenerators in sections
and with contracted flues substantially in the manner and for the purposes setforth.
Third. Constructing open hearth regenerative furnaces having Hackney ports with
a movable hearth and fixed or movable roof or flues.
Fourth. Disposing regenerators and connecting them to furnaces when there are
two or more furnaces so that one or more of the regenerators may be coupled to either
or any one of two or more furnaces for the purpose setforth.
Fifth. In open hearth regenerative furnaces providing means for heating regenera-
tors substantially as setforth.
Sixth. In open hearth regenerative furnaces the combination of two or more of the
improvements herein specified.
