APPARATUS FOR USE 1N DECOMPOSING METALLIC SALTS AND DESULPHURIZING GRES.

SPECIFICATION forming part of Letters Patent No. 399,122, dated March. 5, 1889.

Application filed January 3, 1889. Serial No. 295,368. No model.)

To aZZ whom, it may concern:

Be itknown that we, PHINEAS il. ADAMS, Jr., and ORSEMAS T. X. ADAMS, citizens of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Apparatus for use in Decomposing Metallic Salts and Desulphurizing Orcs, of which the following' is a specilication.

The object of our invention is to improve an apparatus for mechanically decomposing chemical compounds, metallic salts, and desulphu rizing ores or their resulting material, when the substances treated are in a molten condition, b v the action of centrifugal force; and our invention consists in the features and details ot' construction hereinafter described and claimed. i v

In the drawings, Figure l is a vert-ical lon- `gitudiual section of our apparat-us with the running-gear in elevation. Fig'. 2 is a transverse, vertical section taken in the line 2 2 of Fig. l, showing* the arrangement of the actuating-shaft and the means employed to prevent friction, looking in the direction of the arrow. Fig, tl is a plan viewof the bottom or end ot' the receivingwessel. Fig'. 4 is an elevation showingl the entranoepipe, lookingI ont trom the interior of the receiving-vessel; and YFig'. shows the receiving-vessel somewhat modified in form.

ln making' our improved apparat ns for decomposing.;l chemical compounds, met allie salts or salts ot' metal, and desulphnrizing'ores,wc make a vessel, Y, constructed and adapted lo receive the substance to be treated when in a molten condition. This receiving-vesselmay 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 curbingand have a removable bottom or end to facilitate the removal of the material which is not thrown oil at the month by the action ot centrifugal force; and in other respects it may be made as will be calculated to subserve the end in view and permit ot its being;` rotated at a high rate oi 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, as they do not form the special Subj ect-matter of our present claims, need notbe more fully described, as they will be sufficiently understood from an inspection of the drawings. The receivingwessel, however, is intended to be rotated'in a horizontal instead 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 'in horizontal journals or bearings supported in a suitable frame-work, which may be indicated by the letter B. This frame work will of course be of a size and strength adequate to sustain the heavy weight of the receivingvessel with its load of molten material. One of the journals, C, may be a plain bearing or box, in which the outer end ot the actuatingshaft rests and revolves. The other bearing,

D, however, we prefer to make as shown in Fig. 2, where it consistsfof a box adapted to receive a number of rollers or wheels, E, preferably journaled in suitable bca-rings in the sides of the box and affording' just snl'iicient space in the center t'or the passage of the actuating shaft, so that its surface will bear against the surface of the wheels or rollers E. ily this arrangement cxtreme or in jui-ionsfriction will be prevented between the actuating-shaft an d t-he bearings as it operates under the heavyY load or strain to which it will be subjected, as hereinafter described.

The pulleyv or belt surface F is connected to any convenient source of power, so as to rotate the actuating-shaft and the receivingvessel to which itis attached. The inner end of the actuating-shaft is provided with a collar, G, which has tlanges Il. (Shown in section in Fig. l.) This collar, with its iianges, is keyed or otherwise iixed to the actuatingshaft, so that it will rotate as it revolves. The flanges H are connected to the bottom or end ot the reeeiving-vessel in such a way as to carry the receiving-vessel around wit-h their revolutions. XVe pret'er to form this connection in a way that will permit some yieldability or iexibilitv between the parts, and

IOO

the parts apart from each other to the extent allowed by the bolts. At the same time the presence of thesesprings will permit sufficient play to accommodate any vibration that might occur in the receiving-vessel while being rotated at a high rate ot' speed, and at the same time permit'the actuating-shaft to be rigidly held in a horizontal position without being sensibly affected by the vibrations of the receiving-vessel.

NVe have thus described and illustrated a manner of attaching` the receiving-vessel to the actuating-shaft to permit of sufficient flexibility to accommodate the parts to the vibrations ot' the receiving-vessel in operation; but as other means can obviously be used to secure a flexible or yieldable connection, we do not desire to unnecessarily limit ourselves to details of construction in this particular.

The receiving-vessel, as before said, is intended to be arranged i`n a horizontal position. Its mouth is made sufficiently open to permit a constant inflow of molten material to be treated, while at the same time it serves for the discharge of the material which is thrown off by the action of centrifugal force. To permit this we prefer to introduce the molten material through a pipe or spout, J, which enters the mouth of the receiving-vessel at a slightly-downward inclination and carries the material to be treated almost to the bottom or farther end of the vessel. This pipe or spout leaves sufficient space around it to per mit the passage of the molten material thrown off by the action of centrifugal force; and to retain the heat in the receiving-vessel We prefer to arrange a plate or cover, X, before its mouth, provided with a suitable hole for the admission of the pipe or spout. This cover may be made adjustable toward and from the mouth of the receiving-vessel, it desired, to regulate the space between them. To catch the material as it is thrown oft we prefer to arrange a chamber, K, into which the mouth of the receiving-vessel opens. This chamber is surrounded by a curbing or other means to catch the molten material as it isthrown olf, and means may be employed, as a pipe, L, to discharge streams or jets of Water onto such material in order to prevent overheating. A

Aspout is arranged at the bottom of this chamber, through which the molten material thrown olf may pass to a car, H, or other receptacle adapted to receive and remove it. To heat the interior of the receiving-vessel,

or to prevent it from cooling during an interruption of its operation, orV for other purpose, we also prefer to provide a furnace, N, by means of which` a blast of air, driven by a blast-fan or other means, may be heated and discharged into the receiving-vessel, as shown in Fig. l.

In Fig. 5 we have shown the receiving-vessel as enlarged and separable at the mouthy end, instead of at the otherend, as shown in Fig. l. This modification is for the purpose of facilitating the removal of that portion of the material treated which is not thrown ofi by the action of centrifugal force, if it be preferred to remove at that instead of at the other end of the receiving-vessel.

What we regard as new, and desire to secure by Letters Patent, is-

l. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten state, the combination of a horizontal revoluble receiving-vessel adapted to receive molten material to be treat ed, a horizontal revoluble actuating-shaft rotating said vessel as it revolves, a pipe or spout entering the receiving vessel through its mouth and discharging the molten material to be treated into the receiving-vessel at or near its farther end, means for supplying heat to the interior of the receiving-vessel, and means lfor rotating the actuatingshaft, substantially as described.

2. In an apparatus for decomposing metal lic salts'or salts of metals and desulphurizing ores when in a molten state, the combination of a horizontal revoluble receiving-vessel adapted to receive molten material to be treated, a horizontal revoluble actuating-shaft rotating said vessel as it revolves, a pipe or spout entering the receiving-vessel through its mouth and discharging the molten material to be treated into the receiving-vessel at or nearits farther end, a plate or cover before the mouth of the receiving-vessel, with space between the plate or cover and the mouth of the receiving-vessel for the discharge of the molten material thrown off by the action of centrifugal force, and means for rotating the actuating-shaft, substantially as described.
