It will thus be seen ter.

Vertical each chamber communicating only with the strengthening-ribs C are formed radially at central gas-duct. too 50 intervals upon the outside of the receptacle, I will now proceed to describe the use of the extending upward from the flange B to the apparatus in connection with the electrolytic reduction of lead ore, such as galena or sulfid of lead. The ore to be reduced is placed in the bottom of the receptacles to a depth which leaves a short interval between the top of the mass and the under surface of the next re-' ceptacle above it, and the electrolyte, consisting of one part of pure sulfuric acid to ten of water, is then poured in to a level higher than the bottom of such next receptacle. The conducting-wire P from the positive pole of the source of electricity is connected with the top receptacle of one stack, preferably by clamping it upon one of the ribs (1. The bottom receptacle of this stack is electrically connect-ed to the top receptacle of the next stack, and so on, the circuit being finally completed at the bottom receptacle of the last stack, which is connected with the negative pole by the wire N. The shields E by insulating the side walls of the receptacles restrict the current to a substantially vertical path through the mass of ore, and thus prevent the ineffectual short-circuiting which would otherwise occur. The sulfureted hydrogen gas which results from the foregoing operation passes out through the tubes f, 650., into the central gas-duct, by means of which it is conducted to any proper point of discharge for utilization or otherwise. face of the receptacle facilitates the escape of the gas rising from the ore.
When it is desired to remove the contents, the top receptacles of the respective stacks can be successively lifted off and dumped by tilting upon their trunnion-bearings,the other receptacles of the series remaining sealed, as above.
In the form shown in Fig. 7 the general configuration of the receptacle is the same as that just described; but instead of providing the flange B with a lip upon its extreme periphery I obtain a similar result by means of the downwardly-projecting rib b, which engages with the inner face of the top of the subjacent receptacle' In the type shown in Figs. 8 and 9 the necessary reduction in diameter at the lower portion of the receptacle is obtained by constructing the side or wall with an offset a, which also affords the bearing-surface for seating the receptacle upon the next one of the series. This offset may be provided with a downwardly-projecting lip, such as a, or may havea countersunk bearing-surface in the form of a channel, such as a to afford a seat for the top edge of the next receptacle. In this instance the gas-orifices a are located in the wall above the offset, and corresponding holes are formed through the insulatingshields E and B", respectively.
I have shown these variations of detail to illustrate a few of the embodiments which the invention permits; but I of course do not limit my claims to the precise types shown. It is only necessary that the receptacles shall be capable of superimposition in vertical series The tapering under surwith proper interspaces for ore and electrolyte and that a proper bearing-surface shall be afiorded for securing a close joint between the top edge of one receptacle and the region of contact with the next one, the combination 'being such as to permit the proper location of gas-orifices.
I claim 1. The combination, of a series of superposed metallic receptacles, each having its lower portion of less diameter than the upper edge, and each having an exterior peripheral seat arranged below said upper edge but conforming throughout its whole extent with such edge, said receptacles being respectively provided with external gas-escape orifices adjacent to said seat,whereby a series of whollyisolated chambers having individual escapeoritices is formed, substantially as set forth.
2. An element for an electrolytic series consistingofa metallic receptacle havingitslower portion of less diameter than its upper portion; an exterior peripheral flange arranged below its edge, said flange being provided with an orifice; and a series of radial strengthening-ribs adjacent'to said flange, substantially as set forth.
3. The combination, with an element for an electrolytic series consisting of a metallic receptacle having its lower portion of less diameter than its upper portion, and an exterior peripheral seat arranged below the upper edge; ofan insulating-shield fittingagainst the side wall of the cell and extending outward over the top edge thereof, substantially as set forth.
4:. An element for an electrolytic series consistingofamet-allic receptacle havingits lower portion of less diameter than the upper portion, in combination with an exterior peripheral seat arranged below its upper edge, and means, substantially as set forth, for providing trunnion-bearings, whereby said receptacle may be tilted to discharge its contents.
5. The combination of a gas-duct; a series of superimposed metallic receptacles, each having an exterior peripheral seat adapted to engage with the top edge of the subjacent receptacle, and an orifice adjacent to said seat; and a series of tubes leading from said orifices to said gas-duct, substantially as set forth.
6. An element for an electrolytic series consisting of a metallic receptacle havingits lower portion of less diameter than the upper portion and having a bottom surface which is inclined upward radially from the center to the outer periphery, in combination with an exterior peripheral seat arranged below the upper edge, and an orifice adjacent to said seat, substantially as set forth.
