Refonte FOR Priooucme BISULPHmE oF CARBON.

n 1speinatinrormng part of Letters Patent No. 1 i2,a9o, daten March 7, ieri.

.y ,-I, THOMAs SIM, of Baltimore, 1n the county t ofBaltiniore andStateof.Maryland-.have intvented a newff and Improved Retort for 'ProducingiBisulphideof, Garbomrc., of which the the Intentan.

"fMy"inventionisintended to obviate a diflii culty heretoforel experienced in cleaning re- `torts `for-the manufacture ofbisulphide of cary honor other fluids produced by the combinai tionfof two slids,whereinthe temperature of tvaporization of` said fluid and one of its com- [ponent solids differs considerably. e

It is particularlydesighed `for the produc tion of` bisulphide,oftfrbom permitting the C vaporized sulphur` to ascend freely through fthe carbon and avoiding clogging the lower part ofthe reto`rt,as`well; as allowing the refuse i `mass left afterithetoperation` is completed to t i beireadlywithdrawnfron the retort. i i Y `In retorts of this classit has hitherto been necessary tolwithdrawl the refuse from the "aperture at top,` that being the only one projxvided for both filling and emptying. This was atedious andtronblesomeproeess. t `Descripiionof thcAcconwanymg lbjctua'ngs.`

. t is the retortfsupported in any proper manner over the `furnace I, and surrounded 2 with anfinner` wall,G, and outer Wall, H, of

betweenthe retort and inner inner wall" preventing the llame from coming fin direct `eontactwith the retort, thereby insuring in uch greater durability.

"Gis, the neck of theretort, throughwhich `charcoalis introduced, the aperture4 thereof.

having attached a circular plate operated by a screw, and fitted tightly to the orifice or other equivalent.

A is a pipe, provided with a suitable vapor tight cover, of sufficient size to allow ready access to the interior of the retort, and passing 4through the interior and exterior walls of the furnace.

.- D is a grate near the bottom o'f the retort,

`thus preventing clogging, and allowing the sublimed sulphur to thoroughly permeate the coal.

A pipe, O, is connected with the neckof the retort near its top. This pipe is enlarged throughout a portion of its length, or conducted into a chamber'of greater sectional area than itself, forming a sulphur-trap, O'. This part isinclined downwardly from the retort, and is surrounded by a furnace, K.

The pipe M, issuing from O', is surrounded by a condenser, P. After passing th two branches-Ona M', leading downwardly Lto the tank or reservoir for receiving the condensed bisnlphide, and the other, M, passing upwardly through a second condenser, P', is led to asuitable place for the discharge of the incondensible vapors.

The above-described arrangement of the sul; phurtrap and its connections may, however, be varied without affecting the general principles of construction and operation of the same.

Operation.

A charge of charcoal being introduced through the aperture C, this is closed and sulto the bottom of the retort. All means of exit for the gases, except through the pipe O, being then closed, and lire started in the furnace I, when the retort becomes sufficiently heated to vaporize the sulphur, the' vapor passes up forming bisulphide of carbon, (GS) which passes over in gaseous form through the pipe i0, and is conducted off by M to the condenser `P, where the greater portion of itiis condensed, tpassing down through the pipe 'M'. The ini condensible gases generated in the retort,and

`The above-described arrangement may be replaced, as shown in the drawing, by a cap,

servingto separate the sul phur in its solid form from contact with the superimposed charcoal,

mughthis it is uividedinto o phur inserted into the pipe B, passing down through the carbon, combining therewith and any uncondensed CS, mingled therewith, are carried upward by the pipe M through the second condenser P', where the remaining bisulphide is condensed, theincondensible gases being nally discharged by the pipe M. The vaporiform free sulphur which may have passed through the retort is condensed within the sulphur-trap O. and drawn off in a molten state through the opening e as often as requisite, say once a day, the furnace K being heated whenever necessary for this purpose. The sulphur is fed to the retort as often as required (at intervals of five to ten minutes, more or less) th rough the tube B, the door' of which is opened by means of the lever b, and reclosed as soon as the proper charge is introduced. Fresh charges ot' charcoal may be su pplied at intervals of two to three days. The refuse mass remaining in the retort is withdrawn, when necessary, through the cleaningout pipe A.

I do not claim the sulphur-trap O', it being the invention of Elias S. Hutchinson, of Baltimore, Maryland.

Claims.

I claim as my inventionl. The cleaning-out pipe, A, provided with a vaportight cap or cover, in combination with a retort, constructed and operated substantially as herein described.

2. In combination with a retort and its connections, as herein described, the gate D, substantially as and for the purposes specified.

3. In combination with a tube, B, for intro- 'ducing materials into the body of a retort, the

hinged cover b and forked lever or collar b', substantially as and for the purposes specified.

4. In combination with a retort and its appendages, constructed and operating substantially as herein described, the arrangementiof an interior and exterior wall, formingre and air spaces above the furnace Lsubstantially as and for the purposes described.
