PROVISIONAL SPECIFICATION.
Improvements in the Construction of Furnaces for Puddling or
Heating and other Purposes.
HARRY RYLANCE HAIGH 3 Arboretum Square, Derby Engineer, do hereby
declare the nature of this invention to be as follows:-
An improvement in the construction of furnaces for puddling, or heating and
other purposes for the purpose of economically promoting the complete combustion
of the fuel, and thus ensuring the prevention of smoke.
It is well known that the admission of highly heated air to a furnace assists
combustion.
My improvements consist in constructing the furnace, with a jacket or casing,
as shewn on the accompanying drawings, so arranged that the heat at present
lost by radiation from the furnace and its belongings, may be economically applied
to heating air, which is afterwards used in the furnace, to promote complete
combustion, and thus ensure the absence of smoke.
For this purpose I construct round the sides, and crown of the furnace, and its
belongings, or of either, an outer casing of brick, or suitable metal, leaving a
space or cavity, between the casing, and walls of the furnace proner. Openings
or ports marked A, are placed at suitable positions in this outer casing for the
purpose of admitting atmospheric air to the cavity or space, aud this air then
travels backwards and forwards one or more times, through the cavity or space
around the furnace and its belongings, until it becomes in a highly heated condition-
it is then caused to enter the furnace proper by a port or ports marked B constructed
in the crown of the furnace near the bridge.
I prefer this port or ports to be formed in such a manner, that the hot air
enters the furnace in thin streams, which ensures its thorough mingling with the
gases from the fuel thereby producing complete combustion with an intense flame.
and with the absence of smoke.
If desired the highly heated air may be caused to enter the furnace both above
and below the fuel, and may be forced in by artificial means, or drawn through by
the natural draught of the furnace.
A furnace constructed in this manner would be much more comfortable for the
men to work, as the outside is cool owing to the radiated heat from the brickwork
being absorbed by the air passing through the cavity or space.

COMPLETE SPECIFICATION.
Improvements in the Construction of Furnaces for Puddling or
Heating and other Purposes.
HARRY RYLANCE HAIGH 3 Arboretum Square, Derby, 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:-
An improvement in the construction of furnaces for puddling or heating, and
other purposes-for the purpose of economically promoting the complete combustion
of the fuel, and thus ensuring the prevention of smoke.

page_text: My improvements consist in constructing the furnace, with a jacket, or casing,
as shewn on the drawing accompanying the Provisional Specification, so arranged,
that the heat at present lost by radiation from the furnace, and its belongings,
may be economically applied to heating air, which is afterwards used in the
* Inace, to promote complete combustion, and thus ensure the absence of smoke.
For this purpose I construct round the sides, and crown, of the furnace, and its
belongings, or of either, an outer casing of brick, or suitable metal, leaving a space
or cavity, between the casing, and walls of the furnace proper. Openings or ports
marked A, in the drawing referred to, are placed at suitable positions in this outer
casing, for the purpose of admitting atmospheric air, to the cavity or space, and
this air then travels backwards, and forwards one or more times, through the cavity
or space around the furnace, and its belongings, until it becomes in a highly
heated condition-it is then caused to enter the furnace proper, by a port or
ports marked R-constructed in the crown of the furnace near the bridge, as shewn
on the drawing.
I prefer this port or ports to be formed in such a manner, that the hot air
enters the furnace, in thin streams, which ensures its thorough mingling with the
gases from the fuel, thereby producing complete combustion, with an intense flame,
and with the absence of smoke.
If desired the highly heated air may be caused to enter the furnace, both above
and below the fuel, and may be forced in by artificial means, or drawn through by
the natural draught of the furnace.
A furnace constructed in this manner would be much more comfortable for the
men to work as the outside is cool owing to the radiated heat from the brickwork
being absorbed by the air passing through the cavity or space.
Having now described the nature, arrangement, and purpose of my invention, I
declare that what I claim is―
(1) A cavity or space between the main walls forming the body of the furnace,
and the outer casing, as shewn on the drawing, for the purpose of heating atmospheric
air, by the hot brickwork, during its passage through this space, and before it enters
the furnace.
(2) The combination of the methods set forth, of and for the purposes
described.
Dated this 4th day of September 1891.
