RICHARD HANSON Plate and Sheet Roller JAMES FERNEE Gas furnace Manager
both of Chantrey Road Woodseats Sheffield we do hereby declare the nature of this
invention to be as follows:-
Instead of the Hearth of furnace being supported upon Metal Plates and Bearers as
hitherto constructed. We fix the furnace Hearth upon solid Brickwork supported by
strong Arches and within the said Arch or Arches we place Heat and Air passages
which enables us to obtain intense heated Air, also keeps the bottom of furnace
Hearth in a highly heated state, this liqufying the Bath of Molten Metal equally at
bottom of furnace as well as the top of Bath.
HEATED AIR AND WASTE HEAT.
To attain this intense heat we utilize the waste heat (that formerly as been allowed
to escape up the Chimney Stack) by bringing it down underneath the furnace bottom
(as previously described) amongst the Air Passages whence it passeth all around them
thus delivering up its heat before passing to the Chimney Stack.
By this method of heating the Air it assists in attaining perfect combustion.
APPLICABLE PURPOSES.
This process of generating heat can be applied wherever heat is required and is so
simple yet effective (being made either continuous or reversible in its action) that it.
can be regulated and controlled to any temperature of heat required and be readily
managed by Workmen also it can be adapted to all kinds of furnaces without resorting
to any artificial means such as Steam and Compressed Air.

page_text: By thus strictly adhering to Nature's Laws we attain by this method the requisite
heat required for all heating and smelting purposes upon such an economical basis not
. hitherto attained.
CLAIMS.
Having thus described the nature of our Invention and in what manner the same is
to be performed, we claim as a specialty
The solid Brickwork Bottom supported with an Arch or Arches with heat and air
passages underneath built with brickwork.

RICHARD HANSON Plate and Sheet Roller JAMES FERNEE Gas furnace Manager both
of Chantrey Road Woodseats Sheffield do hereby declare the nature of our invention
for IMPROVEMENTS IN OPEN HEARTH FURNACES, WHICH IMPROVEMENTS ARE APPLICABLE
ALSO TO OTHER HEATING PURPOSES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
Instead of the Hearth of furnace being supported upon Metal Plates and Bearers as
hitherto constructed we fix the furnace Hearth upon solid Brickwork supported by a
Strong Arch or Arches within the said Arch or Arches. We build flues to convey the
products of combustion also to convey the volume of Air required for ignition and
combustion.
This method enables us to obtain highly heated Air. Also keeps the furnace Bottom
in a highly heated state, thus assisting to liqufy the Bath of Molten Metal equally at
the bottom of furnace as well as at the top of Bath.
To attain this intense heat. We utilize the waste heat (that formerly as been allowed
to escape up the Chimney stack) by bringing it down underneath the Hearth of
furnace (as previously described) amongst the Air passages or flues, thus giving up its
heat on its way around and underneath the heated Air-Chamber to the Chimney stack.
This process of generating heat can be applied wherever heat is required, and is so
simple and effective (being made either continuous or reversible in its action) that it
can be regulated and controlled to any temperature of heat required and can be easily
& readily understood in its management by workmen, also it can be adopted to all
kinds of furnaces, Kilus, Ovens or Stoves without resorting to any artificial forces to
attain perfect combustion.
EXPLANATION OF THE DRAWING.
Figure 1 showeth the ground Plan of Gas-producer P, Heated air Chamber H
Furnace chamber F, and the heat or smoke flues S.
Figure 2 showeth a longitudinal side elevation of. P, H and F, illustrating the
manner the Air A is conveyed to the point of ignition with the gas G as shown by
Arrows. Also the Bath B in F, with Doors O and the Metal Lander R with Tap-hole,
also the Dampers D for regulating the current & temperature, and showing the way
which the flues S convey the products of combustion in transit to Chimney stack.
Figure 3, section showeth the solid Brickwork bottom supported by an Arch also
the Air passages A and the heat or smoke passages S, underneath and within the
aforesaid Arch.
Figure 4, section showeth, the front elevation of H, and the manner the Air is
discharged into H up and through chequered brickwork, discharging at the top over

page_text: the Gas-port G, in the way thus described, into the furnace chamber F also showing
the flues S as they ascend over H.
Figure 5, section showeth, the side elevation of P, describing its interior formation
with set-offs around and above the Grate E also the Ash-pit W with an inclined front
for conveying the fuel on to E which is received from the Hopper C worked by a flap
& Lever to discharge into P. Also showing the way the Gas is conveyed from P to F
by arrows, through a Tower flue T. Also the steps to descend to W and to ascend to
the top of P, as described by X.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is.
The solid Brickwork bottom supported by an Arch or Arches with the Air and heat
passages underneath in the manner described.
