IMPROVEMENTS IN FURNACES FOR MELTING, PUDDLING AND RE-HEATING STEEL, IRON, AND IRON ORE
Year: 1884

page_text: I THOMAS BARLOW-MASSICKS of The Oaks, Millom in tho County of Cumberland
Ironinaster, do hereby declare the nature of said Invention for IMPROVEMENTS IN
FURNACES FOR MELTING, PUDDLING AND RE-HEATING STEEL, IRON, AND IRON ORE
to be as follows:-
The object of my Invention is to improvo the construction of furnaces for
melting, puddling or re-heating steel, iron and iron ore so as to obtain greater
facilities for cleansing such furnaces and removing the dust and other waste
products that accumulate in the regenerator and also to obtain a more extended
distribution of the gas and air employed in heating the furnace.
I carry these objects into effect by forming separate connections for the admission
of air to the furnace and so preventing the air from passing through the joints of
the brickwork and coming into contact with the gas as heretofore until the moment
when the air descends through the roof when it comes into contact with the gas
issuing from the regenerator and thus the greatest intensity of heat is obtained at
the point where it is most needed.
The gas issuing from the regenerator is conducted through a number of passages
inside the furnace and extending the full width of the furnace or nearly so thus
forming a passage for the gas and waste products of combustion alternately.
Air is conducted through suitable tubes or passages at the ends of the furnace to
a number of pigeon holes or openings built or formed in the roof of the furnace,
preferably at each end: those pigeon holes are covered by a loose top or casing
with an enlarged semicurcular or suitably shaped end: this loose top may be
removed at any time for cleansing purposes or repairs without interfering with or
stopping the furnace. The usual reversing arrangements and regenerators are
employed and suitable cleaning doors are fitted in the gas passages leading from
the regenerator.

page_text: I THOMAS BARLOW-MASSICKS, of The Oaks, Millom, in the County of Cumberland,
Ironmaster, do hereby declare the nature of said Invention for IMPROVEMENTS IN
FURNACES FOR MELTING, PUDDLING, AND RE-HEATING STEEL, IRON AND IRON ORE,
and in what manner the same is to be performer, to be particularly described and
ascertained in and by the following statement:-
The object of my Invention is to improve the construction of furnaces for
inelting, puddling or re-heating steel, iron and iron ore or other metals so as to
obtain greater facilities for cleansing such furnaces and removing the dust and
other waste products that accumulate in the regenerator and also to obtain a more
extended distribution of the gas and air employed in heating the furnace.
I carry these objects into effect by forming a separate connection for the
admission of air to the furnace and so preventing the air from passing through the
joints of the brick work and coming into contact with the gas as heretofore, until
the moment when the air descends through the roof, when it comes into contact
with the gas issuing from the regenerator and thus the greatest intensity of heat is
obtained at the point where it is most needed.
The gas issuing from the regenerator is conducted through a number of passages
inside the furnace and extending the full width of the furnace or nearly so thus
forming a passage for the gas and waste products of combustion alternately..
Air is conducted through a suitable tube or passage at the end of the furnace to
an opening built or formed in the roof of the furnace, preferably at either end;
this opening is covered by a loose top or casing with an enlarged semicircular or
suitably shaped end; this loose top may be removed at any time for cleansing
purposes or repairs without interfering with or stopping the furnace.
The usual reversing arrangements and regenerators are employed and suitable
cleaning doors are fitted in the gas passages leading from the regenerator.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, referenco
being had to the figures and letters marked thereon.
Figure 1 is a sectional elevation of a furnace to which my improvements are
applied. Fig. 2 is a transverse section of the upper part of the furnace and Fig. 3.
is a plan of the same.
a are the walls of the furnace and b is the tube or passage communicating with
the atmosphere and through which air passes upward under the loose top or cover c
and downward through the top of the furnace to the openings d through which it
enters the combustion chamber e; ƒ are a number of gas passages through which
gas is conducted from the regenerator to the combustion chamber c; these passages f
extend the full width, or nearly so, of the chamber e and are placed immediately
below the openings d, so that the air for combustion desconding through the said
openings impinges directly upon the gas issuing from the passages and thus causes
an intense heat to be directed on the burden in the combustion chamber c.
The other end of the furnace is constructed in a similar manner, the passage bl
corresponding with the passage b, the loose cover c' with the cover c, the openings d'
with the openings & and the passages with the passages f.
b
When air and gas are admitted through the passages band d and respectively
the waste products of combustion pass out of the furnace through the passages
and fas indicated by the arrows on the drawing Fig. 1 and when the action of
the furnace is reversed air is admitted to the combustion chamber e through tho

page_text: passages band and gas through the passages f¹ and tho products of combustion
pass away through the passages & and 6 and f.
The loose tops or covers o caro semicircular in form and are so fitted that they
may be removed at any time when required for cleansing the passages or for other
purposes without interfering with the working of the furnace: there are covers
at g g¹ and cleaning doors at hh' which can be removed for the purpose of cleaning
out the passages whon required.
"
Having now particularly described and ascertained the nature of my said
Invention and in what manner the saine is to be performed
I declare that what I claim is-
1. The combination of parts forming the improved furnace for molting,
puddling, or re-heating steel, iron and iron ore or other metals, substantially as and
for the purposes herein shown and described.
2. In a furnace for melting, puddling, or re-heating steel, iron and iron ore or
other metals, the use and application of one or more loose tops or covers c c¹,
substantially as herein set forth for the purpose specified.
