Improvements in Centrifugal Apparatus for Treating Molten
Material.
1, ORRIN BURTON PECK, of 162, 34th Street, Chicago, Illinois, United States
of America, Mining Engineer, 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
This invention relates to centrifugal apparatus for use in the treatment of molten
materials, and it has for its object to improve the construction of the same.
said invention relates more particularly to the construction of the curbing that
surrounds the receiving-vessel, and to the provision of means for protecting its
interior.
In the accompanying drawings :
Figure 1 is an elevation, partly in section of a centrifugal machine embodying
my improvements.
Figure 2 is a section of Figure 1 on the line 2, 2 looking in the direction of the
arrows.
Figure 3 is an outline view of a portion of the curbing and lining shown in
Figure 2, and
Figure 4 is a perspective view of one section of the lining.
V is the receiving-vessel; A the shaft for supporting and revolving the
same; B, B journal-bearings for supporting and maintaining the vertical position
of the shaft; E the curbing surrounding the vessel; F, plates forming the top
and bottom of the curbing; f, f, flanges on such plates; G, a plate forming the
wall of the curbing; I, a lining or protector for the interior of the curbing; J a
ring or shelf upon which the lining I rests; i, bolts for holding the lining in place ;
and a ring passing around the curbing, through which the bolts i extend.
The receiving-vessel V is surrounded by a strong curbing E, preferably con-
structed out of two cast-iron or other suitable plates FF, preferably provided with
annular flanges ff. These two plates constitute the top and bottom of the curbing,
and are preferably held together by means of a sheet of boiler iron or steel rivetted
or otherwise secured to the flanges ff. In this way the sides or wall of the
curbing is preferably as shown in Figure 1. The curbing serves to catch and
confine the material that is treated in the receiving-vessel and discharged from it.
The material is discharged or thrown off from the receiving-vessel in a molten
condition, but water is sprayed on it from the pipe h or other convenient means,
cooling and hardening it and rendering its action upon the interior of the curbing or
wall very severe, rapidly wearing the curbing at the point where it first strikes, and
in this way the wall is soon cut or worn entirely through, thus rendering the
curbing unfit for further use.
To afford a protector for the interior of the wall of the curbing, and to prevent it
from being rapidly destroyed, I have provided a cast-iron or other suitable lining, I,
preferably made in sections and placed on or over the interior of the wall of the

page_text: curbing, and located in such a manner that as the material from the receiving
vessel is discharged it will be thrown against the lining instead of the wall proper.
In this way it will be seen that the lining I will be worn instead of the wall, and
that when the protector or lining is worn so that it is not fit for further use it may
be removed and a new one put in its place. I prefer, as above stated, to make this
lining in sections, and, as shown in the drawings, I prefer to secure the sections in
their place by means of bolts i that extend through the lining and curbing, with
their ends carrying the nuts on the outer side of the curbing, so that they are easy
of access. I also prefer to provide a ring around the outside of the wall of the
curbing at any suitable point for the bolts i to pass through. The ring is to
facilitate the easy locating of the bolts i, since, as I prefer to wrap the outside of
the wall between the edges of the flanges f. f with wire to secure the required
strength it would be quite a difficult matter to extend the bolts through the wire
wrapping if the ring was not provided.
;
To assist in holding the sections of the lining in place, I prefer to provide a ring
or shelf J, upon which their lower ends
may rest. While I have shown this lining
as only covering a portion of the interior of the curbing of course it may be extended
down as far as desired; and while I prefer to make it in sections, as shown, which
facilitates its easy removal and renewal it may be made in larger pieces, or as will
best suit the operator, so long as it is arranged to protect the interior of the
curbing and as I have also shown, I prefer to make the various sections of the
lining so that their edges will lap to prevent the small particles thrown from
the receiving vessel from being driven between the edges of the sections of the
lining. This is a matter of choice, and does not very materially effect the utility
of the lining; also as shown in the drawings, I prefer to provide recesses in the
inside of the lining at the point where the bolts that hold it in place are located,
so that the heads of the bolts may set in them, so to speak, or be countersunk,
leaving a comparatively level surface on the interior of the curbing and lining, so
the material will not stick.
The lining may be made in various ways and held to place in various ways, as by
keys; wedges, or recesses; but as the intention of my invention is to afford a means
for protecting the interior of the curbing from severe injury or being rapidly worn
out and destroyed by the material discharged from the receiving-vessel, I do not
wish to be limited to any particular form of constructing or securiug such protector
or lining.
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 :-
First. In a centrifugal machine for the treatment of molten material, the com-
bination of a revoluble receiving vessel adapted to receive the material to be treated
means for supporting and revolving the vessel, a surrounding curbing for arresting
the particles thrown off from the receiving-vessel, and a removable lining on the
interior of such curbing to prevent it from being rapidly worn out and destroyed by
the action of the discharging material from the receiving-vessel, substantially as
described.
Second. In a centrifugal machine for the treatment of molten material, the com-
bination of a revoluble receiving-vessel adapted to receive the material to be
treated, means for supporting and revolving the vessel, a surrounding curbing for
arresting the particles thrown off from the receiving-vessel, and a lining composed
of removable sections on the interior of such curbing to prevent it from being
rapidly worn out and destroyed by the action of the discharging material from the
receiving-vessel, substantially as described.
Third. In a centrifugal machine for the treatment of molten material, the com-
bination of a revoluble receiving-vessel adapted to receive the material to be
treated, means for supporting and revolving the vessel, a surrounding curbing for
arresting the particles thrown off from the receiving-vessel, and a lining composed

page_text: of removable sections held to place by means of bolts extending through the lining
and curbing from the interior to the exterior, substantially as described.
Fourth. In a centrifugal machine for the treatment of molten material, the com-
bination of a revoluble receiving-vessel adapted to receive the material to be
treated, means for supporting and revolving the vessel, a surrounding curbing for
arresting the particles thrown off from the receiving-vessel, a covering or envelope
or wire around the exterior of the curbing a ring or band around the exterior of
the curbing, a removable lining on the interior of the curbing, and bolts to maintain
the lining in place, extending through it and the curbing, and through the ring
on the exterior of the curbing, substantially as described.
Fifth. In a centrifugal machine for the treatment of molten material, the com-
bination of a revoluble receiving-vessel adapted to receive the material to be
treated, means for supporting and revolving the vessel, a surrounding curbing for
arresting the material thrown off from the receiving-vessel, a removable lining on
the interior of such curbing to prevent it from being rapidly worn out and destroyed
by the action of the discharging material from the receiving vessel, having bolts
extending through such lining to hold it to place and the lining having recesses on
its interior to accommodate the heads of such bolts thereby affording a smooth
interior surface to the lining, substantially as described.
