PROVISIONAL SPECIFICATION.
An Improved Process and Apparatus relating thereto for the
Manufacture of Carburets.
We, MAX KANDLER, Engineer, and CLEMENS WEINER, Merchant, both of
Thomasmühle, Leipzig, Germany, do hereby declare the nature of this invention
to be as follows:-
The present invention relates to an apparatus for the manufacture of carburets
from alkaline earth metals by means of a voltaic arc, and that in a continuous
manner.
The apparatus consists of several electric furnaces symetrically arranged round
a central and common chimney stack.
These electric furnaces have an annular rotary casing in the form of a trough
passing through them, the speed of rotation of which will be regulated in any suitable
manner. This casing rolls on rollers rotating on axles sealed in the walls of the
furnace, and its bottom is provided with a lining of coal charcoal or carbon in
the shape of a mould, which mould formed the mass of coal, charcoal or carbon
serves to receive the liquid carburet, which, after cooling will be broken and
removed when it passes between the furnaces.
The annular casing or trough with its mould formed of a mass of coal or
charcoal constitutes, after a sliding or rolling contact has been established, one
of the poles of the furnace. This annular pole may be fixed or put in motion as
has been hereinabove mentioned, and that by means of any suitable transmission
gearing.
Above this annular pole is suspended in the interior of each furnace, a charcoal
pole fixed or movable, provided with an arrangement of any suitable description
which will admit of its wasting away being compensated for by a convenient
regulation.
The materials to be submitted to fusion are poured or charged upon the side
of the annular pole facing towards the interior of the furnace, and that, in such
a manner that they form horizontal or vertical layers of material separated from
one another, which can be effected by means of change hoppers, shaking shoe-
pieces, and of conveying chutes. The materials thus heaped up may besides be
slightly compressed by the passage of suitable cylinders, so as to prevent the
occurrence of pulverization in the electric flame. The heaping up in layers has
the result that the layer of lime serves to transmit the heat, whilst the layer of
coal, charcoal or carbon conducts the electric current, and that the formation of
the carburet will not be effected in the flame itself, the heat of which would be
too high, but at some distance from this flame. The running off of the carburet
formed prevents the interruption of this latter, inasmuch as it only passes through
the flame for an instant at half height.

Manufacture of Carburets.
We, MAX KANDLER, Engineer, and CLEMENS WEHNER, Merchant, both of
Thomasmühle, Leipzig, in the Empire of Germany, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement: -
This invention relates to the manufacture of carburets from metals, the object
being to provide a new method of manufacturing and an improved apparatus for
carrying the same into practice, in which a revoluble ring-channel is employed
to receive the substances, said ring channel being moved through the flame of an
electric furnace, where the carburet is produced, the latter being removed from
said channel after cooling and the manufacture being thus continued without
interruption as more clearly and fully pointed out and claimed hereinafter.
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is cross-section of my improved electric furnace;
Fig. 2, is longitudinal sectional view of same;
Fig. 3, shows the arrangement of the charging hopper and the shoes and chutes
thereof;
Fig. 4, is a general plan view of three electric furnaces preferably arranged
around a common chimney.
The electric furnaces may be of any form, dimension and capacity, but are prefer-
ably as shown in the drawings the lower part thereof being open to receive a
revolubly mounted ring-channel A, the speed of which is controlled in any suitable
way, and the bottom of said channel having a mould like lining of carbon A¹;
said mould serves, to receive the substances before passing through the flame and
to hold the liquid carburet produced in said flame and removed from the mould
after cooling between the furnaces. The ring-channel A may be slowly rotated
in any suitable way, but preferably the same is arranged on rollers 1 journaled in
suitable brackets secured to the walls of the furnace, and the underside of said
channel is provided with a rack 2 receiving motion from a gear-wheel 3, journaled
in a frame 4 which supports a second gear-wheel 41 meshing with the former and
made integral with a further gear-axle. The gear-wheel 5 receives motion from
a suitable pinion 6 on shaft 7, journaled in suitable bearings 8 and rotated by
any suitable power.
The ring channel A in combination with its lining A¹ constitutes one of the
electric poles of the furnace after being thrown into circuit by means of any
sliding or rolling contact..
Above said ring-pole and within the furnace is hung a stationary pole B pro-
vided with any suitable controlling device M for compensating wearing thereof.
The substances to be melted are charged upon the upper face of the ring pole
so as to form horizontal or vertical separate layers: in the furnace shewn in the
drawings, the substances are charged through suitable hoppers C C arranged side
by side from which said substances are forced to enter chutes E E after having
travelled over hopper-shoes D D so as to form vertical layers F1, F2. It will be
obvious that these substances may be charged in any other way without departing
from the scope of the invention."
The substances may be furthermore compressed to a certain extent by the passage
of a suitable roller or cylinder, to avoid or lessen pulverisation of said substances
as they are moved through the flame,

page_text: By this arrangement of the substances, like particles are in contact with one
another, which constitutes a very important feature for the conduction of heat and
the electric current; and among the main advantages of the new process is a real
saving of electric current and a decrease of wearing of the electrodes.
The lime will be melted before the coal is converted into graphite,
80 that at the moment, the coal is converted into graphite, calcium
vapors are already evolved and carburet produced therefore, thus avoiding over-
heating, elevation of coal, and dissociation of carburet, since the substances are
continuously moved through the flame and the produced carburet immediately
removed therefrom.
The aforegoing arrangement of the substances, results in the fact that the layer
of lime serves to conduct heat, whilst the layer of coal will conduct the electric
current, the carburet being produced at a short distance from the electric flame.
As the produced carburet flows off immediately after formation, the same is pre-
vented or nearly prevented from being dissociated by the action of the flame,
since it is submitted to said action but for a very short time.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim is:
1. An improved process of manufacturing carburets, which consists in submitting
metallic oxides or carbonates and coal to the action of the flame of a suitable
electric furnace, substantially as set forth.
2. An improved process of manufacturing carburets, which consists in sub-
mitting metallic oxydes, or carbonates and coal, piled up in horizontal or vertical
layers, upon one of the electric poles of the furnace, to the action of the flame of
said furnace, substantially as set forth.
3. An improved apparatus for manufacturing carburets, consisting of one or
several electric furnaces arranged in any suitable way, one pole of which is
revolubly mounted and serves to receive the substances to be melted, the second
pole of said furnace or furnaces being stationary, substantially as set forth.
4. An improved apparatus for manufacturing carburets, consisting of a plurality
of electric furnaces symetrically arranged around a common chimney, and one
pole of which is revolubly mounted and serves to receive the substances to be
melted and to hold the produced carburet, the second pole of said furnaces being
stationary, substantially as set forth.
5. In an electric furnace for manufacturing carburets, the combination with a
revolubly mounted ring-channel having a suitable lining to constitute one of the
electric poles of said furnace and to receive the substances to be melted and to
hold the produced carburet, of a second pole hung over the former and means for
adjusting the same, substantially as set forth and for the purpose specified.
6. In an electric furnace for manufacturing carburets, the combination with a
revolubly mounted ring-pole receiving the substances to be melted and holding the
produced carburet, of a second adjustable pole of the substances to be melted
hung in a horizontal or vertical layers upon said ring-pole, substantially as set
forth and for the purpose specified.
