Improvements in Apparatus for Use in Decomposing Chemical
Compounds, Metallic Salts, and Desulphurizing Ores.
We, PHINEAS HAZEU ADAMS Jr., and ORSEMAS THEOPHILUS XENOPHON ADAMS,
both of 31 South Canal Street Chicago, Illinois, United States of America,
Mechanics 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 object of our invention is the construction of an improved apparatus for
mechanically decomposing metallic salts and desulphurizing ores or their resulting
material, when the substances treated are in a molten condition, by the action of
centrifugal force; and our invention consists in the features and details of construction
hereinafter described.
In the accompanying drawings
Figure 1 is a vertical section, with the running gear shown in elevation.
Figure 2 is an enlarged view of some of the parts of the receiving vessel shown in
Figure 1, and
Figures 3, 4 and 5 are details of some of the parts.
In making our improved apparatus for decomposing chemical compounds, metallic
salts or salts of metal and desulphurizing ores, we make a receiving vessel V, con-
structed and adapted to receive the substances to be treated, when in a molten
condition. This receiving vessel is mounted and rests upon an actuating shaft A, to
which it is fixed or keyed in such a way that by the rotation of the shaft the receiving
vessel will be revolved. The receiving vessel may be made in such a way as will
secure the required strength, and reduce the conduction of heat from the interior to
the exterior. It may be surrounded by a curbing, and have a removable bottom, or
be otherwise separable, preferably in the plane of its largest diameter, to facilitate
the removal of the material not thrown off by the action of centrifugal force. And,
in other respects, it may be made as will be calculated to subserve the end in view,
and permit of its being rotated at a high rate of speed, for the separation of particles
of different degrees of density in the matter treated. Many of these parts, and the
details of their construction, except as hereinafter described, need not be more fully
explained, as they will be sufficiently understood from an inspection of the drawings."
In order to supply heat to the interior of the receiving vessel before it is set in
operation or to maintain a high temperature in it during intermissions of use, or for
any other reason, we prefer to provide the receiving vessel with a fire pot B, which is
preferably made of a series of coiled tubes, through which water may be kept con-
stantly circulating, as shown in Figure 1 of the drawing, although any refractory
material, capable of withstanding the intense heat to which it will be subjected, and
possessed of the required strength, may be used. This fire pot, as we have called it,
may form simply an annular chamber, leaving a hole through the middle, through
which the molten material may be poured or introduced into the receiving vessel.
This is the way we have shown it in the drawings. The upper portion of the fire
pot is preferably riveted, or otherwise fastened to a ring (, formning an angle iron, or
LD037

page_text: in other words, to a ring with flanges extending out horizontally at its upper and
lower edges. When made with two flanges the upper portion e rests upon a lip or
flange adapted to receive, it in the general cover of the apparatus, while the lower
flange c' extends over the mouth of the receiving vessel and forms a cover to the
same. While we prefer to fasten the upper end of the fire pot to a ring provided
with these flanges, other means may be employed to support it in proper position, and
the cover c¹ for the mouth of the receiving vessel, may be made independent of the
ring C, and supported in any convenient manner. The external diameter, of the fire
pot is preferably enough smaller than the internal diameter of the mouth of the
receiving vessel, as to leave a small annular space around the fire, pot, through which
and between the top of the receiving vessel and the cover c¹ the material thrown off
by the action of the centrifugal force may be discharged, as it constantly rises from
the bottom of the vessel. A pipe D leading from a fan blower or other blast, may be
employed to drive a current or blast of air into the fuel space of the fire pot, so as to
maintain combustion. The cover E of the fire pot is also preferably mado removable,
to facilitate the introduction and removal of fuel, ashes, cinders, or other matter. As
before described, the whole fire pot may be entirely lifted out, and removed from the
receiving vessel, whenever it is desirable to do so.
Around the top of the receiving vessel we prefer to provide or fasten a ring F,
which may he riveted or otherwise fastened to the outside of the receiving vessel, as
shown in detail in Figure 4. But this ring instead of forming a distinct piece, made
separately and put on may consist in a thickened portion, integral with the outer
shell or case of the receiving vessel. It affords a shoulder or stop against which the
cover or envelope of wire coiled around the receiving vessel to increase its strength
may be wrapped and firmly held from displacement. We also prefer to provide the
receiving vessel with a band or hoop G, about half way down from the top, as shown
in detail in Figure 5, which is secured to the receiving vessel, or formed integral
therewith, and which is provided with studs g, which enable the receiving vessel to be
lifted out or handled by a bail or by hooks, operated by a crane, or in any other con-
venient manner. Of course eyes or similar devices may be employed in the place of
the studs g.
Around the bottom of the receiving vessel we prefer to employ a reinforcing
piece H, which may be described as a ring fitting around the outside of the shell or
case for the receiving vessel, and provided with a flange extending out horizontally,
to enable it to be securely fastened or bolted to the bottom, as shown in Figure 3.
But of course this reinforcing piece need not be a separate piece, as it is obvious that
it may consist in a thickened portion of the shell or case of the receiving vessel at
its base and angle for the same purpose. It thus strengthens the receiving vessel,
and assists in affording sufficient thickness to enable the bottom of the receiving
vessel to be securely bolted to its sides. This is the more important from the fact
that the outside, shell or case of the receiving vessel, the one against which the wire
is wrapped may be made of thin or light material, while yet affording sufficient
strength for the purpose, if reinforced' as it is by the wire; but when light material
is thus used, the wire can only give it the requisite lateral strength against a lateral
pressure, leaving it necessary or at least advisable, to provide means to reinforce it at
the base and angle where it turns out, to secure it against the upward strain to which
it is subjected. We therefore consider it quite important to provide the receiving
vessel with this, flange or collar H. After wrapping the receiving vessel with wire
to as many layers or coils of thickness as may be desired, we prefer to provide it
with a light covering or jacket I; which fits outside of the wire cover, and protects
the wire from being cut or broken when the receiving vessel is moved about, and also
prevents the unwinding of the wire, should one of its strands become accidentally
broken. But in order to permit the air to have access to the wire, and if desired, for
purposes of cooling the receiving vessel, we prefer to provide the outer casing or
jacket I, with perforations, which will permit the access desired.
In constructing the receiving vessel we prefer to make it with an outer shell or

page_text: case K, reinforced and strengthened at the base and angle, and provided with a ring
or shoulder at or near the top, sustaining the wire, and a band or hoop affording
means for bandling the receiving vessel, as above described, and with an inner
lining J, of a size and shape externally to fit within the shell or case. The outside of
this lining is also preferably provided with grooves, channels or indentations, forming
spaces in the walls, to reduce the conduction of heat from the interior to the exterior.
We also prefer to strengthen the receiving vessel by wrapping coils of wire L, around
the outer shell or case, and to protect the wire from injury by a cover or jacket I.
All of these features which enter into our preferred construction, are plainly shown in
Figure 2.
Having now particularly described and ascertained the nature of our said inven-
