Steel, or other Metal.
I, NIELS CARL FREDERIK JOCHUMSEN of 1 Marsh Street, Barrow in Furness, in
the County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
The invention consists mainly in so constructing the furnaces, that the molten
metal flows from the melting place into an annular main receiver formed round the
bottom of the furnace. From the said main receiver it flows through openings near
the bottom into one or more extra receivers. In connection with each of these extra
receivers is a slag receiver, into which the slag flows from main receiver as well as
from extra receivers through suitable passages.
The heated gases collected in main receiver, extra receivers, and slag receivers, are
drawn into an annular space formed round the blast tube, which thus forms an injector,
forcing the heated gases with the blast into the melting place. The spout with tapping
hole is connected to main receiver, through which the molten metal has to flow or pass
from extra receivers.
Referring to Drawing:-Fig. 1. is a vertical section taken through the centre of the
melting place and receivers.
Fig. 2 is a transverse section of slag and gas receivers taken through the line E. F.
in Fig. 1.
Fig. 3. is a horizontal section of furnace, taken through the line A. B. in Fig. 1.
Fig. 4. is a horizontal section of receivers taken through the line C. D. in Fig. 1.
The iron or other metal is melted in place a in the usual manner, and flows through
openings into main receiver b. From the metal flows into extra receivers c,
through openings. When the metal reaches the height of openings, the slag,
which floats on the surface, flows into receivers d. Receivers c and d are provided
with slag holes m.
when
The heated gases from receivers b, c, and d, are drawn into receivers through
openings n, and then injected into the melting place a through passages o;
uniting with the air blast, the gases are ignited and consumed in the melting place a,
thus effecting a saving in fuel and more rapid melting.
Dated this the 6th day of July 1887.

page_text: I, NIELS CARL FREDERIK JOCHUMSEN, of 1, Marsh Street, Barrow-in-Furness, in
the County of Lancaster, 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:-
This invention consists principally in so constructing the furnace, that the molten
metal flows from the melting place into an annular main receiver formed round the
bottom of the furnace.
From the said main receiver it flows through openings near the bottom into one or
more extra receivers. In connection with each of these extra receivers is a slag
receiver, into which the slag flows from main as well as from extra receivers through
suitable passages near the top of extra receivers and slag receivers, are slag holes.
The heated gases collected in main receiver, extra receivers, and slag receivers, are
drawn into an annular space round blast tube, which forms an injector, and forces the
heated gases with the blast into the melting place. The spout and tapping hole are
connected to the main receiver, through which all the molten metal in extra receivers
has to pass.
Referring to the drawings filed with the provisional specification:
Figure 1 is a vertical section taken through the centre of the furnace and
receivers.
Figure 2 is a transverse section of slag and gas receivers, taken through the line E, F,
in Figure 1.
Figure 3 is a horizontal section of furnace taken through the line A, B, in
Figure 1.
Figure 4 is a horizontal section of receivers taken through the line C, D, in
Figure 1.
a is the melting place, main receiver of annular form, e extra receivers, d slag
receivers, e blast tube with annular gas receiver around it. Into this gas receiver,
gas from any convenient point is introduced, or in place of, or as well as gas, gas pro-
ducing materials, such as coal, wood, peat, petroleum, or the like, can be injected or
placed therein. These may be partially consumed or coked or vaporised by the hot air
passing over the slag in c and d and entering at n. The iron (or other metal) is melted
in the space a in the usual manner, and flows through openings into main receiver b.
From 6 the metal flows into extra receivers c through openings k. When the metal
reaches to the height of openings i, the slag floating on the surface, flows into receivers d.
Receivers c and d are provided with slag holes m.

page_text: The heated gases from receivers b, c, and d are drawn into receiver through
openings n, and then with the gas injected into the melting place through nearly
annular holes o, by the force of the blast through tube e, the gases from are ignited
when joining the blast, and are consumed in the melting place a, thus effecting a
saving of fuel and causing rapid melting. is the blast tube conveying air to the
blast pipe.
Figures 5 to 11 are additional drawings filed with this specification, and showing
slight modifications of the apparatus.

The parts common to Figures 1 to 4 are marked by the same letters as in those
Figures.
It will be seen in these additional drawings, which are for a small furnace, that the
slag chamber à is dispensed with, that additional area of passagen for heated air and
gases from the chamber e, has been provided, that facilities for admitting gas generating
materials are provided, not merely to the chambers e or, but also at s,s, beyond chamber,
also that the passages from chamber fare enlarged and additional radial passages p, p,
provided, conveying the mixed gas and air to various points of chamber a, instead of
admitting them at two points only, it being found that this gives a little better result,
and is less severe upon the furnace. The remainder of the details in the new design,
are so similar to, or identical with those of the design shown in the provisional
specification, as to require no further remark.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
1st. The improvements in the construction of furnaces for melting iron, steel, or
other metal, whereby gas is generated and injected into the furnace with the blast, so as
to aid the fuel in the furnace, substantially as described.
2nd. The improvements in the construction of furnaces for melting iron, steel, or
other metal, whereby a large quantity of metal can be stored in a heated state without
rising to an inconvenient height in the furnace, also whereby the spare heat of the
slag and metal can be utilised to assist in making gas for injection into the furnace,
substantially as described.
3rd. The general arrangement of furnace for melting iron, steel or other metal,
constructed as a whole, substantially as described.
