SPECIFIGTION forming part of Letters Patent No. 399,123, dated March 5, 1889.

Application filed January 3, 1889.

To ZZ whom it may concern.-

Be it known that we, PHINEAS H. ADAMS, Jr., and Onsnnns T. X. ADAMS, citizens of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Apparat-us for Use in Decomposing Metallic Salts and Desulphurizing Orcs, 0f which the following is a specification.

The object of ourinventionis to improve an load of molten material. Une of the journals,

apparatus for mechanically decomposing metallic salts and desulphurizing ores or their resulting material, when the substances treated are in a molten condition, bythe action of centrifugal force; and our invention consists in the features and details of construction hereinafter described and claimed.

Fig. 2 is an end elevation of adetail on the line 2 of Fig. l, looking in the ,V Fig. 3 is an end elerious friction will be prevented between the direction of the arrows. vation of a detail on the line 3 3 of Fig. l,

looking in the direction of the arrow; and j under the heavy load or strain to which it will Fig. el is a vertical longitudinal section of the receiving-vessel, with a furnace for supplying it with a heated blast.

In making our improved apparatus for decomposing chemical compounds, metallic salts, or salts of metals, and desulphurizing ores, we make a vessel, V, constructed and adapted to receive the substances to be treated when in a molten condition. This receivingvessel 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 maybe surrounded by a curbing and have a removable bottom or end 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. iMany of these parts and the details of their construction, as they do not form the special subjectmatter of our present claims, need not be more fully described, as they will be sufficiently understood from an inspection of the drawings. The receiving-vessel, however, is

intended to be rotated in a horizontal instead Serial No. 295,369. (No model.)

of a vertical position, and therefore necessitates a special adaptation of various parts to this end, as hereinafter described.

An actuating-shaft, A, is arranged inv horizontal journals or bearings supported in a suitable frame-work, which maybe indicated by the letter B. This frame-work will, of course, be of a size and strength adequate to sustain the receiving-vessel with its heavy C, maybe a plain bearing or box in which the outer portion of the actuating-shaft rests and revolves. The other bearing, D, however, we prefer to make in the form of a box adapted to receive a number of rollers or wheels, E, profe ably journaled in suitable bearings in the sides of The box and affording just sufficient space in the center for the passage of the actuating-shaft, so that its surface will bear against the surface of the whe-els or rollers. 3y this arrangement cxtreme or injuactuating-shaft and thebearing as it operates be subjected, as hereinafter described.

The actuating-shaft is provided with a pulley or belt surface, F, connected with any convenient source of power, so as to rotate the actuating-shaft and the receiving-vessel to which it is attached. The inner end of the actuating-shaft is preferably provided with a collar, G, which is keyed or otherwise lined to the actuating-shaft, so that it will rotate as it revolves. The end of the receiving-vessel opposite its moutl'1,through which the molten material to be treated is introduced, is preferably provided with an exten sion, H, of larger internal diameter than the mouth through which the molten material is introduced. The end of this extension is preferably made removable, so as to permit access to the receiving-vessel for any desired purpose, although we prefer, also, to make the receiving-vessel separable at the point of its largest diameter, l, as shown in the drawings. This will enable any material to be removed which is not thrown off by the action of centrifugal force. rllie end of the receiving-vessel, beyond the extension H, is preferably provided with a further extension, J, which surrounds or incloses the collar G on the 'inner end of IOO the actuating-shaft. These extensions Il and J are separated. from each other by the partition or end K of the extension ll, The collar G is preferably provided with studs g, and coiled springs connect these studs with the inner sides of the extension J. This will be readily understood from an inspection of Fig. 2 of the drawings. A bolt or pin, L, passing loosely through the extension J and rigidly through the collar G and actuatingshaft A, serves to connect the parts together, and causes the receivingvessel to rotate with the rotation of the actuating-shaft. The

springs interposed between the collar G and the inner sides of the extension J form such aflexible or yieldable connection between the two that, while supporting or sustaining the weight of the receiving-vessel, they will permit suliicient play between the extension J and the collar G as to accommodate them to the vibrations of the receiving-vessel in operation without subjecting the actuatingshaft Vto that strain which would be occasioned were they rigidly united.

ln order to further support the mouth end of the receiving-vessel, we prefer to provide it with a ring or collar, M, affording a beltsurface, surrounding the extending mouth of the receiving-vessel, with a small annular space between them. This ring or collar is preferably sustained by bolting it to a collar, N. provided with an inwardlyprojecting flange to accommodate the location of anumber of springs between it and the vflange O, which extends from the case or wall ofthe receiving-vessel. These springs are shown in Figs-l, 3, and 4, and they form a ilexible or yi eldable connection between the m outh end of the receiving-vessel and the ring or collar M, which is preferably sustained by a belt to la shaft, Q, as shown in Fig. l. They permit the necessary play to accommodate the parts to the vibrations of the receiving-vessei when in use. These springs are indicateiil by the letter o.

` lVe prefer to provide the extension ll of the receiving-vessel with a number of holes, S, through which the material thrown olfl by the action of centrifugal force may be discharged. In making the extension 'l with an internal diameter somewhat larger than the internal diameter of the mouth of the receiving-vessel the material thrown off by the action of centrifugal force will be caused to be discharged at this en d instead of at the mouth, while by making the diameter of the extension llconsiderablysmaller than the internal diameter ofthe receiving-vessel an annular chamber or recess is provided around the ou ter edge of the receiving-vessel to catch and retain the heavier particles of the material bcing treated, while the lighter portion is driven through the receiving-vessel into the extension to the holes S, where it is discharged, as shown in Fig. l. To catch t-hc material discharged through the holes S and enable it to be properly carried away, we prefer that these holes shall open into an annular chamber oil trough, R, into which the material is discharged, and from which it Hows through a spout at the bottom to a car or other vessel, to permit it to be conveyed away.

In order to heat the interior of the receiving-vessel, or to prevent it from becoming cool when there is anyinterruption in the admission of molten material to he treated, we prefer to employ a furnace, T, with a pipe entering the mouth of the receiving-vessel, to admit of a hot blast being driven into such vessel. The production and application of this heated blast by means of the furnace T differ in no material respects from the production and application of otherheated blasts,

and need not be minutely described in detail. This furnace may be omitted or modilied, if desired, as well as various other features illustrated in the drawings-as, for instance, thej' outer curbing and the means for conveying away the molten slag and other similar matters.

In order to counterbalance the weight of the receiving-vessel and its superimposed load exerted on one end of the actuating-shaft, we prefer to extend the other end of the actuating-shaft beyond the journal C, and provide it with a pulley or belt, U, and connect it with a belt to a pulley or belt-surface, lV, as shown in Fig. l. By properly tightening the belt connecting those two pulleys, for

which means are provided, as shown in Fig. 10o

l, the outer end of the actuating-shaft may be prevented from bearing against the upper part of its bearing C with extreme or injurious friction. le have shown, also,in dotted lines another means for securing this same 105 which, if desired, may be only large enough 115 to permit this. Before the admission of ma-` terial to be treated the receiving-vesselis preferably brought to a rotation of several thousand revolutions per minute. As the material falls into the receiving-vessel it will, izo

instantly be acted upon, and the heavier par-- ticles of the material rapidly carried tothe sides of the receiving-vessel. As new material ows in, and the annular space or chamber around the inner sides of the receiving- 125 vessel fills up, the lighter particles constantly comin g to the inside and the heavier particles passing to the outside, the lighter particles will be driven by the action of centrifugal force through into the extension H, where 13o they will be forced out through the holes S and carried off, as above described. As soon as sufficient material has been introduced into the vessel to cause the lighter particles This, however, 11o

to begin to be forced through the extension H and out through the holes S there will be a constant and uninterrupted discharge of the lighter particles of the material as long as the stream ot' molten material is flowing into the vessel through the mouth. The separation, ot course, begins as soon as the materia-l is deposited in the receiving-vessel near its mouth, and as it is driven along toward the other end of the vessel the separation becomes more and more perfect, until by the time of its discharge it is practically free from all of the heavier and more valuable particles. After the operation has been continued long enough to secure a suficientbodyot the heavier particles of the material around the sides ot' the receiving-vessel, the vessel may he stopped, and the body oi hea-vier particles7 still mostly in a molten condition, if desired, removed by opening the vessel at the end, or in any other convenient Way. In this way the vessel may he operated again and again, with short intermissions for emptying the heavier particles which have accumulated around the sides.

What We regard as new, and desire to se eure by Letters Patent, is
