APPARATUS FOR THE MANUFACTURE OF CARBON BlSULPHlDE CPFGIFIGATIQI-l' forming part of Letters Patent No. 321,661, dated July 7, 1885.

Application filed July 15), 1884. (X0 model.)

To all whom it may concern:

Be it known that I, EDWARD R. TAYLOR, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Apparatus for the Manufacture of llisulphide of Carbon; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in apparatus for the manufacture of bisulphide of carbon; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section of my improved apparatus through the center of the rctorts and longitudinal with the furnace. Fig. 2 is afront elevation of the same, with the attached pipes and condensing apparatus shownin section. Fig. 3 is avertical section of condensing-tubes that are a continuation of those shown in Fig. 2. Fig. 4 is a view in perspective of the lower retort. Fig. is a longitudinal vertical section of the same. Fig. (5 is an enlarged vertical section of a portion of the said lower retort. Fig. 7 is an enlarged vertical section of the man-hole plate.

A represents the main retort, and consists of a hollow cast'iron cylinder provided with an upper head and man-hole plate, A, that has an opening, a, of considerable size that is closed by the stopper a. This stopper is preferably in the form of two cones united at their base and provided with a long handle. By means of this peculiar shape the stopper is easily drawn up through the charcoal and as easily returned to its seat. The part A is also provided with the flanged nozzle A], for the attachment of pipes, as hereinafter shown. The part A is open at the lower end, and rests upon a subretort that is also of cast-iron, and has a hollow rectangular part, B, and an upright hollow cylindrical part, B, that are integral and their respective inclosed chambers in open relation with each other. The part B is closed at the bottom and open at the top, as shown in Figs. 1, t, and 5, and has an offset upwardly-projecting flange, 7), leaving a shoulder, b,

on which the part A rests, and a tight joint is made by packing clay or other refractory material between the flange 1) and the part A. The front end of the part B extends through the furnace front, and is provided with book lugs b, that hold the cross-bar b This bar has a setscrew, Z), in the central part that holds the head or cover 13 against the end of the part B, as shown in Fig. 2, the joint between the parts 13 and B being also packed with clay or other suitable material. The subretort rests upon the arch D, that spans the fire-boxlaterally, but is less in length than the fire-box, leaving a space at either end of the arch for the upward passage of the products of combustion, as shown in Fig. 1. On top of the retort A is secured the cylindrical charcoalcontaiuer 0, provided with a removable cover, G, and is inclosed by the jacket 0, that is provided with the smoke-pipes c, and extends to near the bottom of the part 0, where it joins the brick-work, as shown in Fig. 1.

E is the fire-box, E the grates, and E a plate covered on top with brickwork, over which the fuel is passed to the grates. The grates, as shown, are located some distance from the furnace-front, so that more heat will pass up the rear passageway and around the retort A, where the greatest heat is required. The furnace is provided, in the usual manner, with the furnace-door c and. the ash-pit door 0'.

F is apotfor melting sulphur, and has a removable cover, F, and has a hole at the bottom closed by the stopper A flaringtube, f, conducts the melting sulphur to the subretort. This tube is liable to become clogged with sediment from the sulphur, to prevent which the tubeis considerably larger than the hole leading to it from the sulphurpot, and increases in size toward the sub-retort, as shown. This tube is usually located near one side of the pot, so that the handle of the stopper f is more out of the way. The brick-setting G inclosing the retort is, above the furnace, preferably pyramidal, so that the hot-air chamber H around the retort A is contracted about the upper end of the retort, and the heat thereby more or less confined in the chamber. The walls extend above the retort A, as shown, so that the chamber H is in open relation with the chamber it, that surrounds the container 0. The front wall is breasted out at G and made to incl osc the chamber H front passage-way from the furnace.

around the sulphur-pot. the chambers H and H, and may be provided with a damper, z, to control the amount of heat admitted to the chamber H. The tubes that conduct the vaporized products from the retort A to the condenser have usually been the source of much annoyance. The expansion and contraction of the parts rendered it extremely difficult to keep tight joints at the ends of these tubes; also, these tubes are liable to become clogged with free sulphur that is carried over with the volatilized products. To remedy these difficulties, I have devised the following-described mechanism: To the flanged nozzle A I bolt the flanged end of the angular pipe J, one leg of which is vertical, as shown in Fig. 2, and has near the bottom attached the inverted cup J, the depending rim of which extends into the annular recess or cup is of the sulphur-box K. The cup It is filled with glyeerine or other liquid that will retain the vapor in the box and exclude the air. The tube J may, therefore, be raised or lowered a trifle by the expansion or A flue, I, connects contraction of the retorts without injury. The

upper ends of the part J are provided, re spectively, with the removable stoppers j. These stoppers may at any time be removed, and the free sulphur that is lodged in either leg of the pipe may be removed by a scraper, the straight legs in line with the respective stoppers rendering all parts of the tube accessible. The volatilized products that pass through the pipe are heavier than air and will not pass out at the upper ends of the pipe when the plugs are removed. A pipe, L, provided with the stoppers Z, arranged similar to those just described, and for the same purpose, leads from the box K to the condensing tube M. The latter is a long tube of considerable size, provided at either end with a stopper, N, and is submerged in a tank of water.

In operating the device, the pot F is charged with sulphur and the retort A with charcoal, and a quantity of the latter is had in reserve inthe container 0. After the charcoal has become sufficiently heated in the retort and the sulphur is melted in the pot F, the stopperf is raised, and a quantity of the sulphur is discharged through the tube finto the sub retort and at the part that is directly over the The heat at this part of the sub-retort is sufficient to volatilize the sulphur, which, passing through and combining with the heated charcoal in the retort A, forms the bisulphide of carbon, that passes off through the tube J to the box K, and from thence through the tube L to the condensing-tube M. Any excess of volatilized sulphur that does not thus combine with the charcoal, and that is carried off with the other vapor, will be condensed and collected as free sulphur in the box K, from which, from time to time, it may be removed. As the charcoal in the retort A be comes exhausted of carbon, by raising the stopper a a fresh supply may be introduced from the charger O, and the charger may in turn be replenished by raising the cover C. The charcoal in the charger becomes heated by What would otherwise be wasted heat, that passes from the chamber H through the chamber h, and when introduced into the retort does not retard the chemical union there taking place. Sulphur may from time to time be added to the contents of the pot F, so that there will always be a supply of melted sul phur, and the process of manufacturing the bisulphide of carbon is thus made continuous.

What I claim is 1. In an apparatus for the manufacture of bisulphide of carbon, the combination,'with a furnace, a retort located therein and provided centrally at its upper end with a valve-seat, a eharcoal-container mounted on and communicating with said retort and projecting upwardly above the furnace, and a valve for closing communication between the container and retort, of a jacket in open relation at its lower end with and mounted on the furnace and surrounding the retort, substantially as set forth.

2. In an apparatus for the manufacture of bisulphide of carbon, the combinati0n,with a furnace. open at its top, aretort located therein, a charcoalcontainer mounted on and communicating with the retort and extending upwardly through the open top of the furnace, and a valve for closing communication between the retort and container, of a jacket seated on the top of the furnace and in open relation with the interior thereof and surrounding the greater portion of the container, and smoke-pipes connected to the jacket, substantially as set forth.

In testimony whereof I sign this specifica tion, in the presence of two 19th day of June, 1884. EDWARD R. TAYLOR.
