I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 my invention is to improve the construction of apparatus for
mechanically decomposing metallic salts, or salts of metals, and desulphurizing ores
or their resulting material, when the substances treated are in a molten condition,
by the action of centrifugal force; and my invention consists in the features and
details of construction hereinafter described.
In the accompanying drawings,
Figure 1 represents a vertical longitudinal section of my improved apparatus with
the running-gear in elevation.
Figure 2 represents a plan view taken on the line 2 of Figure 1.
Figure 3 represents a plan view taken on the line 3 of Figure 1.
Figure 4 is a plan view of the mouth of the receiving-vessel shown in Figure 1.
Figure 5 is a vertical section of the mouth of the receiving vessel somewhat
modified, and
Figure 6 is a plan view of such modification.
In the construction of my improved apparatus for decomposing chemical com-
pounds, metallic salts, or salts of metals, and desulphurizing ores I make a receiving
ressel V, constructed and adapted to receive the substance to be treated when in a
molten condition. 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, and in other respects so 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 do not form the special ubject matter of my
claims and need not be more fully described, as they will be sufficiently understood
from the drawings. The receiving-vessel is arranged to be supported on an actuating-
shaft A, which is intended to be connected with a suitable motive power and to be
rotated at a high rate of speed. The receiving-vessel is provided with a lining,
preferably made of cast iron, and of an exterior size and shape adapted to be inserted
in and removed from the outer shell or case of the receiving-vessel. I make the
lining however, of more than one piece, and preferably of two pieces divided
vertically. These two pieces, if two be used, are intended to have a small
space left between their edges, so that there will be, as it may be termed, a "crack"
"open
slit from the bottom to the top on different sides of the lining. These
cracks or slits are intended to permit the lining to expand when subjected to the
great heat of the molten material intended to be treated in contact with it. By
reference to Figure 2, which is a plan view of the section of Figure 1 taken on the
line 2 the cracks or slits will be clearly shown. To cover these cracks or slits and
prevent them from being filled with the molten material treated, and also to assist
in holding the parts firmly together, 1 employ a covering strip or plate B, extending
from the bottom to the top of the lining and of sufficient width to cover and protect
the crack from the material treated.

"
In order to hold the portions of the lining in their proper position with reference
to the outer shell or case of the receiving-vessel, I pass bolts C through the strip
or plate B and through the crack or slit in the lining, and fasten them with nuts on
го

page_text: the outside of the shell or case, as shown in the drawings. Bolts may also be
inserted through holes made in the lining at other places than at the cracks or slits
that I have shown in Figure 3. Where such bolts are used, they should preferably
be arranged at that place where they will least interfere with the expansion of the
lining of the receiving-vessel and in Figure 3 I have shown them arranged midway
between the opposite cracks or slits. In Figure 3 which is a plan view of a section
of Figure 1, taken on line 3, I have shown the strip B as provided winh projecting
bosses D fitting into holes made in the lining at the point where the bolts Care
intended to be passed through. These bosses assist in holding the strips in place
and in strengthening and securing the parts. I prefer, also to make the lining of
the receiving-vessel slightly shorter than the distance between the top of the outer
shell or case of the receiving vessel and its bottom, as shown at E in Figure 1, to
permit vertical expansion of the lining when subjected to heat. The upper portion of
the lining is preferably provided with a separate and removable piece F, which is also
preferably somewhat smaller in diameter than the space in which it is placed, so as to
leave room for expansion at G of Figure 1. The lining for the neck or mouth of the
receiving-vessel is preferably made with vertical recesses or channels, dovetailed in
shape, so that dovetailed blocks H, with channels in their faces, may be inserted into
them. The channels in the faces of the blocks are intended to be slightly deeper
than the interior surface of the neck or mouth so that the material rising to the neck
or mouth of the receiving-vessel by the action of centrifugal force will be discharged
through these channels rather than over the surface of the neck or mouth. These
blocks are preferably made of material capable of standing the heat and wear to
which they are subjected, so that they will last as long as possible, and are extended
slightly above the top of the neck or mouth, so that the discharging material is
kept from contact therewith. As they become worn they may be removed and
other channelled blocks inserted in their places. In Figures 5 and 6 I have shown
a modification of this idea by providing a channelled ring 1, that may be inserted
and removed, instead of the channelled blocks. The use and operation of this
channelled ring are the same as the channelled blocks and need not be described
more minutely in detail.
The
In Figure 1 I have shown a space between the outer wall of the receiving vessel
and the annular tub J, which catches the material discharged from the receiving-
vessel, and from which it may flow or be removed in any desired manner.
annular space may be designated by K, and is covered by a removable annular
ring or plate L. One object of thus providing this covered space is to permit water
to be introduced therein from a pipe or other convenient means to assist in cooling
the receiving-vessel or preventing its becoming overheated when in operation. The
cover L, also prevents any of the material discharged from the receiving vessel
from falling into this space and interfering with the operation of the vessel or the
cooling action of the water. It is made removable, so that when it is desired to
remove the receiving-vessel it may be lifted off out of the way. The inner edge
of the plate
or cover L is preferably fitted around the neck or mouth of the receiving-
vessel in such a way as to rotate with it, and thus force the material falling on it
to pass on out to the receptacle provided for it, and it is therefore shown not
attached to the annular tub or other parts.
Having now particularly described and ascertained the nature of the said inven-
tion, 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 :-
First. In an apparatus for decomposing metallic salts, or salts of metals and
desulphurizing ores when in a molten state, the combination of a revoluble receiving-
vessel adapted to receive molten material to be treated, a neck or mouth having
an opening for the discharge of the molten material and provided with grooves or
channels in and along the sides of the opening and parallel therewith, through which
the molten material flows in discharging and means for revolving said vessel,
substantially as described.

desulphurizing ores when in a molten state, the combination of a revoluble receiving-
vessel adapted to receive molten material to be treated, a neck or mouth having an
opening for the discharge of the molten material and provided with one or more
removable blocks arranged in and along the sides of the opening and parallel
therewith and having grooves or channels therein through which the molten material
flows in discharging, and means for revolving said vessel, substantially as
described.
Third. In an apparatus for decomposing metallic salts or salts of metals and
desulphurizing ores when in a molten state, the combination of a revoluble receiving-
