APPARATUS FOR THE SEPARATION OF VOLATILE PRODUCTS FROM SOLID CAR- LBONACEOTIS MATERIAL. l

Application filed August 20, 1925. Serial No. 51,392.

The present invention appertains to the art of separation of volatile products from. solid carbonaceous material, and has forits purpose to separate from shale rock by heating, crudeoil, andall the by-products of ammonium sulphate, potash, etc. and torecover from spent shale the dye vstuli', paint fillers,

' etc.

The object of the invention is to provide a construction which isboth simple and durableas compared with the intricate apparatus now in common use.

Another importantobject ofthe invention I is to. provide an apparatus which is exceedingly efficient andreliable in its operation, and is able to withstand, the intense heat necessary in the ,cookingprocess. I Vith the apparatus now in use it is necessary, every five or SlX weeks, to replace important parts at a high cost, whereas the present invention obviates these periodical costs and consequently reduces the upkeep. This end is accomplishedby the introduction of a nonnvarping steel cylinder or cylindrical tank which, in actual practice, has withstood a heat of fifteen hundred degrees Fahrenheit without warping or burning.

With the above and numerous other ob jects in view as will appear. as the descriptionproceedsthe' invention resides in'certain novel features of construction, and in the combination and arrangement of parts as Willbe hereinafter more fully described and claimed.

In the drawing The figure is a longitudinal vertical ,se ction through the apparatus.

Referring to the drawing in detail it will be seen that A indicates generally the retort, having mounted therein the usual burn or B, and extending upwardly therefrom the usual stack C. A retort cylinder 5 is mounted across the top of the retort A and is provided with the gas escape openings or conduits 6 which Will lead to suitable condensing apparatus (not shown) but which is well known in this art. of steel of such a quality as tobe nonwarping in spite of the intense heat towhic'h it is subjected. The burner B, of course, is

located immediately below the cylinder. and I extends longitudinally thereof. A shaft 7 is journaled longitudinally of the cylinder 5, andprojects beyond the end thereof. One end of the shaft 7 is operatively connected This cylinder5 is made with a prime mover 8 through a chain 9.- A

funnel lOleads into a cylindrical casing 11.v

In the upperend of the funnel 10 there is rotatably mounted a valve 12 of cylindrical formation having anopening 13 adapted to bebroughtinto registry with thelo'werend of the hopper 14L The shaft15 ofthe valve 12 s opcratively connected with theshaft 7 by a chain 16. The shale is conveyed into the hopper 14 in any suitable manner, and

when the opening 15 registers therewith, the

shale will pour into the valve, and as the valve rotates,the shale poured thereinto will 7 in a spiral alignment, and have paddles 21 mounted on the ends thereof and extending obliquely tothe shaft 7. As the shaft 7 is rotating the shale is picked up from the bottom of the cylinder 5 by these paddles, and caused to circulate about theinterior sur face thereof, at the same time being urged toward the outlet end of the tank. The shale from the tank 5 is finally poured through the opening 23 into the cylindrical casing 2 L communicating with ahopper 26. A screw conveyor 27 isrotatable in the casing 24: and extends longitudinallythereof so that the shale delivered to the casing 24 is con veyed so as to pour into the hopper 26. The shaft of the screw conveyor 27 is operatively connected by a chain 28 to the shaft 7. A valve 29, similar to valve 12,- is rotatable in a casing 30 at the lower end of the hopper 26, and delivers the residue of the shale into the exhaust conduit 31. The shaft 32 of the valve 29 is operatively connected with the shaft 7 by a chain 33.

The vapors formed by the heating procnumber 66 shale through the retort, I oh tain an average of sixty gallons to the ton, While the Government test only obtains forty-two gallons per ton, this experiment was by'weight and liquid measure,

It is thought that the construction, opera- -tion, and advantages'of this inventionwill now be clearly understood by those skilled in this art Without a more detailed description thereof. The present embodiment of the invention has been disclosed by Way of example since in actual practice itattains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent thatchanges in the details of constructiomand in the combination and arrangement of parts may be resorted to Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its'advantages,

Having thus described the invention, What I claim as new is:

1. An apparatus of the class described, in-

I eluding a retort comprising a burner, a cylinder extending across the top of the retort above the burner, and having gas escape conduits leading therefrom, a cylindrical casing leading into the upper portion of one end of the cylinder, andhaving a pair of openings,,one at the bottom thereof, interiorly of the cylinder, and the other at the top thereof, exteriorly of the cylinder, a funnel rising from said other opening, a valve of cylindrical formation and having an opening, said valve being rotatably mounted in the upper portion of the funnel, a hopper rising fromthe funnel, conveyor mechanism in the cylinder, and means for simultane 'ously operating'the valve and the conveyor mechanism. i

2. apparatus of the class described comprising a retort comprising a burner, a cylinder extending across the top of the retort above the burner and having gas escape conduits leading therefrom, a cylindrical 'CEISHIg leading into the upper portion of one end; of the cylinder, andhaving a pair of openings, one at the bottom thereof interiorly of the cylinder, and the other at the top thereof exterior-1y of the cylinder, a screw conveyor rotatably mounted in the cylindrical casing, a funnel rising from said other opening, a valve of cylindrical formation and having'an opening, said valve being rotatable in the upper portion of the funnel, a hopper rising from the funnel, conveyor mechanism in the cylinder, and means for simultaneously operating the conveyor mechanism, the screw conveyor and the valve.

3. An apparatus of the class described including a rctortcomprising a burner, a cylinder extending across the top of the re tort above the burner and having a gas escape conduit leading therefrom, a cylindrical casing leadinginto the upper portion of one end of the cylinder and having a pair of openings one at the bottom thereof interiorly of the cylinder, and the other at the top thereof exteriorly of the cylinder, a screw conveyor rotatably mounted in the cylindrical casing, a funnel rising from said opening, a valve of cylindrical formation and having an opening, said valve being rotatable in the upper portion of the funnel, a hopper rising from the funnel, conveyor mechanism in the cylinder, a second cylindrical casing at the lower portion of the other end of the cylinder and having a pair of openings, one at the; bottom thereof eX- teriorly of the cylinder, and the other at the top thereof interiorly of the cylinder, a hopper leading downwardly from said other opening of the second cylindrical casing, a screw conveyor rotatably mounted in said second cylindrical casing, a valve of cylindrical formation and having an opening, said second mentioned valve being rotatable in th-e lower portion of the second mentioned hopper, and means for simultaneously operating the conveyor nechanisin, the two screw conveyors, and the two valves.

In testimony whereof I aliix my signature.

ROY EBY COTTERMAN.
