PROVISIONAL SPECIFICATION left by the said William. Farnworth and
William Felton at the Office of the Commissioners of Patents on the 26th
1 November 1883.
WILLIAM FARNWORTH of Swindon near Dudley in the County of Worcester
and WILLIAM FELTON of Wilden near Stourport in the said County. "IMPROVE-
MENTS IN OR CONNECTED WITH FURNACES FOR HEATING IRON OR GENERATING
STEAM OR FOR OTHER PURPOSES
"
Our Invention has reference more especially to the furnace described in the
specification of Letters Patent granted to one of us namely William Felton as
of the 13th November 1882 and Numbered 5411 but it may also be applied to
other gas furnaces.
According to our present Invention we make the outer casing of the furnace of
a double sheet iron casing and through the space between the parts of the casing
we establish a water circulation. We may lead the air to the furnace either
directly into the fuel by means of a jet or jets or into a confined chamber below
the fuel which rests in this case upon bars the air passing through hollow fire
bricks, iron pipes or the like to become heated before it enters the furnace. In
case of a long furnace the air may be led from the extreme end of the said furnace
and be passed beneath the sole of the furnace throughout its whole length, and
where there is a boiler at the end of the said furnace we may lead the air first
down through a flue or flues or passage or passages at the side or sides of the
boiler and thence through the passage or passages beneath the sole of the furnace
to the fuel chamber.

by the said William Farnworth and William Felton in the Patent Office on
the 26th May 1884.
WILLIAM FARNWORTH of Swindon near Dudley in the County of Worcester
and WILLIAM EELTON of Wilden near Stourport in the said County "IMPROVE
MENTS IN OR CONNECTED WITH FURNACES FOR HEATING IRON OR GENERATING
STEAM OR FOR OTHER PURPOSES
"
Our Invention has reference more especially to the furnace described in the
Specification of Letters Patent granted to one of us namely William Felton as of
the Thirteenth November One thousand eight hundred and eighty two and
numbered 5411 but it may also be applied to other gas furnaces.
According to our present Invention we may make the outer casing of the
furnace of a double sheet iron casing and through the space between the parts of
the casing establish a water circulation or the ordinary brickwork casing may be
employed. We lead the air to the furnace by means of a steam jet or jets into a
confined chamber below the fuel which rests upon bars. The air for the com-
bustion of the gases may be passed through hollow fire bricks iron pipes or the
like to become heated before it enters the furnace. In case of a long furnace the
said air may be led from the extreme end of the said furnace throughout its
whole length and where there is a boiler at the end of the said furnace we may
lead the air first down through a flue or flues or passage or passages at the side or
sides of the boiler and thence through the passage or passages beneath the sole
of the furnace to the fuel chamber.
And in Order that our said Invention may be fully understood we shall now
proceed more particularly to describe the same and for that purpose shall refer to
the annexed drawing.
The said drawing represents a longitudinal section of a furnace arranged according
to our Invention. The air and steam to beneath the fuel is supplied by the
jet (or jets) C into the confined or closed chamber A below the fuel which fuel
rests upon the bars B The furnace is shewn as constructed of an iron case
containing water. The air for the combustion of the gases from the fuel is
led down through pipes D into flues E extending beneath the sole of the working
furnace. F is a boiler in the heating passages, surrounding which the pipes D
are situated.
Having now described and particularly ascertained the nature of our said
Invention and the manner in which the same is or may be used or carried into
effect we would observe in conclusion that what we consider to be novel and
original and therefore claim as the Invention secured to us by the hereinbefore in
part recited Letters Patent is :-
First The arrangement and combination of parts constituting the furnace for
heating iron or for other purpose substantially as hereinbefore described and
illustrated by the accompanying Drawings
Second. In a furnace for heating iron or for other purpose in which the escaping
or waste gases are employed for heating a boiler or for other heating purpose the
provision of air passages or pipes in connection with the flues or surfaces heated
by the said escaping or waste gases the said air passages or pipes opening into

page_text: other passages or pipes by which heated air is conducted to the furnace to effect
the combustion of the gases substantially as hereinbefore described and illustrated
by the accompanying Drawings.
In witness whereof I the said William Farnworth on behalf of William Felton
and myself have to this our Specification set my hand and seal this twenty
fourth day of May One thousand eight hundred and eighty four.
