RETORTV FOR SUBLINIING. SULFUR.

SPECIFICATION forming part of Letters Patent No. '711,81 1, dated October 21,1902.

Application led April 2l, 1902. Serial No. 104,024. (No model.)

T0 AZZ whom, it' nfl/ay concern:

Be it known that I, ALFREDO ALONZO-CON- SOLI, a subject of the King of Italy, residing at Catania, Italy, have invented a new and useful Improvement in Retorts for Subliming and Refining Sulfur; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention has for its object a new design of retort for refining and subliming sulfur which has on all the other retorts heretofore generally used the advantage of allowing a continuous work with a considerable economy of time and fuel.

The invention is illustrated by the accompanying drawings, and in order to better explain the modiications and the improvements of the new system as compared with the older method, Figure l shows a top view of the retort. Fig. 2 is a section taken on the line 0c of Fig. l, and Fig. 3 is a section taken on the line y y of Fig. l.

In all the several views like parts are designated by the same letters of reference.

According to the system used up to the present the smelting vessel is placed above the retort, with which it communicates by means of a valved tube. The smelting vessel is charged with raw sulfur in pieces, and after this has been melted by the heat developed in the furnace the valve is opened and through it the molten sulfur ows in the second retort.

The rapid introduction into the retort of aV large mass of liquid sulfur the temperature of which is considerably inferior to that of the retort produces a cooling of the latter, and itrequiresa long time, nearlythree hours heating in the ordinary cases,to bring it again to its previous temperature. The sublimation of the whole quantity of sulfur contained in a retort of ordinary size requires about six hours, so that of a working day of twentyfour hours only sixteen hours of actual labor may be utilized, while during eight hours the retort remains inactive, causing a considerable waste of fuel. The new retort avoids all these inconveniences.

ofa bent tube c.

As will be seen in the drawings, the smelting vessel a is placed side by side with va retort b, with which it communicatesby means The vessel a is charged with raw sulfur in pieces, which after melting passes through the tube c into the retort a as soon as it reaches the level f. It is therefore sufficient to keep the melted sulfur at the level g g in the vessel d for maintaining the liquid at the same level in the retort b, wherein the melted sulfur coming from c substitutes continuously the vaporized sulfur. In order to obtain a continuous and uninterrupted feeding, it is only necessary that the raw sulfur be supplied to the vessel c as the melted sulfur descends, so as to avoid its lowering below ff.

It is nearly superduous to remark that the smelting vessel as well as the retort may be of any form and that their position may also be different. The characteristic features of the invention consist in the disposition of two vessels in communication, so as to keep constantly in the one the same level as in the other.

I claim- 1. In a retort for reining and subliming sulfur, the combination with a melting vessel, of a sublimation-retort upon the same horizontal plane therewith, and a communicating tube, the extremity of which within the melting vessel is below the level of the liquid therein, substantially as described.

` 2. In aretort for subliming and refining sulfur, theombination with a melting vessel a, of a sublimation-retort b upon the same horizontal plane therewith, and a communicating tube c, the extremity of which within the melting vessel is bent and below the level of the liquid therein, substantially as described.

In testimony'whereof I have signed this speciication in the presence of two subscribing witnesses.
