Improvements in Metallurgical Furnaces for the Reduction and
Refining of Ores and Metals.
I JOSEPH BAXERES TORRES of 2 Golden Square W., in the City of London,
Doctor-es-Sciences do hereby declare the nature of this invention to be as
follows:-
The new improved "Baxeres metallurgical and siderurgycal furnace," which I
use for the reduction, fusing and refining of every kind of metals, contained in
every kind of minerals or ores, and also for refining the impure metals, for
smelting and making of alloys, and for the reduction and fusing of metallic matts,
dross and salts is illustrated in the accompanying drawings in which :
Fig. I. is a complete sectional view of the furnace.
Fig. II. is a complete sectional view of the gas producer connected with the
furnace and supplying it with the required fuel.
The same letters reffer to corresponding parts throughout.
A is a crucible of metal or metallic alloy, graphite, plumbago, or other form of
carbon, asbestos, porcelain, lime, magnesia, alumina, baryta, or other refratory
bodies of the form represented in the annexed drawings or of any other substances
or mixtures.
B. is the discharge hole, for the reduced, refined metal and the dross.
C. The interior of the furnace in the centre of which the crucible is placed so
as to that it may receive the heat all round it.
D. is a firebrick or other suitable support on which the crucible rests.
E. Walls of the furnace built in fire-clay or other refractory body or combination
thereof.
F. Charging bell.
G. Inlet of hot gases from the gas producer and from the regenerator.
H. Explosion valve.
I. Inlet of cold air who is heated by the heat of the walls of the furnace
through which it circulates.
J. 1st and 2nd inlet of air who is heated by the same.
R. Valves.
L. Outlet for the gases and steam from the inside of the crucible.
M. Rolls for sliding the cover which divides the charging bell from the cupola
of the crucible.
N. Outlet of the gas to the regenerator and then to the chimney.
O. Bed of the furnace.
A and A cupola and lower part of the crucible.
This furnace may be heated by any kind of gas or liquid fuel.
Besides the purpose for which I describe it, the furnace may be used in
connection with many other purposes.
The gas producer Fig. II to supply the furnace Fig. I with the required fuel
consists of:
A. which is a trunco-conical chamber having its larger section at the basis.
B are two step grates serving as air inlets. Each of these grates, whose bars
are hollow, has a complete circulation of water which falls from the top bar by its
overflow to the second bar and so on. This water flow insures the integrity of the
grate; besides it allows to recover the radiation heat producing thus steam which
alves.
L. Outlet for the gases and steam from the inside of the crucible.
M. Rolls for sliding the cover which divides the charging bell from the cupola
of the crucible.
N. Outlet of the gas to the regenerator and then to the chimney.
O. Bed of the furnace.
A and A cupola and lower part of the crucible.
This furnace may be heated by any kind of gas or liquid fuel.

connection with many other purposes.
The gas producer Fig. II to supply the furnace Fig. I with the required fuel
consists of:
A. which is a trunco-conical chamber having its larger section at the basis.
Bare two step grates serving as air inlets. Each of these grates, whose bars
are hollow, has a complete circulation of water which falls from the top bar by its
overflow to the second bar and so on. This water flow insures the integrity of the

Improvements in Metallurgical Furnaces for the Reduction and
Refining of Ores and Metals.
I JOSEPH BAXERES TORRES, Doctor-es-Sciences of 13, Golden Square W.
in the City of London, 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 :-
The new improved "Baxeres metallurgical and siderurgical furnace" which I
use for the reduction, fusing and refining of every kind of metals, contained in
every kind of minerals or ores, and also for refining the impure metals for smelting
and making of alloys and for the reduction and fusing of metallic mattes, dross
and salts is illustrated in the accompanying drawings in which:
Fig. I is a complete sectional view of the furnace.
Fig. II. is a complete sectional view of the gas producer, connected with the
furnace and supplying it with the required fuel.
The same letters reffer to corresponding parts throughout.
A. is a crucible of metal or metallic alloy, graphite, plumbago or other form of
carbon, asbestos, porcelain, lime, magnesia alumina, baryta, or other refractory
bodies, of the form represented in the anned drawings, and of any other
substances or mixtures.
B. is the discharge hole for the reduced refined metal and the dross.
C. The interior of the furnace in the centre of which, the crucible is placed so
as to that it may receive the heat all round it.
D. is a fire brick or other suitable support on which the crucible rests.
E. Walls of the furnace built in fire-clay or other refractory body or combination
thereof.
F. Charging bell.
G. Inlet of hot gases from the gas producer and from the regenerator.
H. Explosion valve.
I. Inlet of cold air which is heated by the heat absorbed by the walls of the
furnace through which it circulates.
J. 1st and 2nd inlet of air which is heated by the same.
K. Valves.
L. Outlet for the gases and steam from the inside of the crucible.
M. Rolls for sliding the cover which divides the charging bell from the cupola
of the crucible.
N. Outlet of gas to the regenerator and then to the chimney.
O. Bed of the furnace.
A¹ and A" cupola and lower part of the crucible.
The gas producer Fig. II, to supply the crucible furnace Fig. I with the
required fuel consists of:
A. which is a conical chamber having its large section at the basis.
This circula-
B. are two step grate serving to support the fuel and as air inlets. Each these
grates, whose bars are hollow has a complete circulation of water.
tion of water insures the integrity of the bars, it allows besides the recovery of
the radiated heat, producing thus steam, which passing through the burning fuel
disassociates producing water gas.

page_text: C. is a fuel charging apparatus placed at the top of the gas producer.
D. is a gas outlet.
E. is an opening with a door open in the lower wall of the producer to shut off
the air.
The drawings referred to as Fig. I and Fig. II, are those filed with the
Provisional Specification.
The furnace already described in Fig. I. may be heated with any kind of gaseous
or of liquid fuel.
Besides the purpose for which I describe it, the furnace may be used in
connection with many other purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In a furnace for fusing smelting and refining all kinds of metals, the com-
bination with a heating chamber, C, of a crucible.constructed as described and
provided with a lower pipe or outlet for the discharge of the melted substances,
reduced and refined metal or alloy and the dross.
2. In a crucible furnace as described, the use of a gas producer as described and
of a regenenerator in connection with it.
