RE'I'ORT.

Application med .Tune 12, me.- Serial No. 115,541.

The object of our invention is to provide simple and efficient means for the distillation of oil shales, carbonaceous materials and'other solid matter, wherein it is desirable to distill and draw off the volatile matter from the solid residue.

Further objects of our invention consist in the placing of two adjacently inclined drums having a common intake and wherein the materials to be treated are fed into the upperly disposed cylinder and the materials to be treated are passed through the same by gravity and the agitation of the same as the materials pass therethrough.

The materials are then gravitated into a second cylinder and passed therethrough by similar means, indirect heat beingiapplied to the materials as the same are passed through each of the cylinders. Means beingprovided for the drawing off of the volatile matter from each of the cylinders at one or more locations.

Still further objects of our invention consist in superposing one of the cylinders above the other and in supplying a single prime mover for actuating the same. In-

ependent sources of heat supply may be used thus permitting of diiferent temperatures being used if desired.

Still further objects of our invention are comprised in the simple construction of the same and wherein the materials to be treated are fed into the cylinders and wherein the materials during treatment are passed through the cylinders is agitated during the passage therethrough. The volatile matter being liberated being drawn ofi at one or more points.

With these and incidental objects in view,

' the invention consists in certain novel features of construction and combination of parts, the essential elements of'which are set forth in the appended claims and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

In the drawings Fig. 1 is a partial side elevation of the so assembled device.

Fig. 2 is a longitudinal sectional view of one of the cylinders.

Fig. 3 is a cross sectional view taken on llne 3-3 of Fig. 2, looking in the direction indicated.

Fig. 4 is a partial sectional view of one of the vaned cylinders disposed within the main cylinder.

'Fig. 5 is a partial longitudinal sectional vlew of one of the cylinders and is made to illustrate primarily the heat supplying pi e disposed central of the main assembly.

ike reference characters refer to like parts throughout the several views.

Two or more cylinders l and 2, are arranged wherein one is superposed above the other and wherein a common feeding hopper 3, is used for the mechanical feedin of the material to, be distilled is used and wherein the same is made to discharge the material into the uppermost of the cylinders. A mechanical feeding mechanism, as a screw conveyor 5, carries the material in a substantially horizontal direction from the feeding h0pper3, and deposits the same into an inclined chute 4:, that delivers the materials into-the upper of the cylinders. The

outer cylinder 1, is stationary and is supported upon supporting blocks 7 and 8 by

legs

9 and 10. Disposed within the outer cylindrical shell 1 are concentric cylinders 11 and 12, each of which has vanes disposed thereupon as is best illustrated in Big. 2 and Fig. 3. The inner cylinder 12 is longer than either of the others and the cylinder 11 is the shorter. -A seal is maintained between the ends of the outer cylinder and the inner cylinder 12 to prevent the escapement of gases being generated therebetween. This seal is maintained through the wearing rings 13 and 14, which are adapted to register with the inner walls of the outer cylinder heads. The seal is further maintained through the medium of the stufiing glands '15 and 16 having take up bolts 17 and'18, for maintaining a constant pressure upon the packing materials. Cylinders 11 and 12 are secured together and turn together. Mechanical means being provided for the rotation of the same. A 100 prime mover, as an electric motor 19, is connected to a line shaft 21 through a suitable driving medium, as a belt 2t). The mner cylinder 12, operates within suitable pillow blocks 24 and 25' and 1s maintained therein during rotation.' ROICSJUOD. 1s 1mparted thereto through .the medium of sprockets and a chain drive 22. the cylinder 12 is rotated the cylinder 11 is also rotated. A series of vanes 23 are secured to the inner periphery of the cylinder 11, and a series of the one bein out of registry with each of the series 0 the other. Thus as the same are rotated, the material will be agitated by the contact with the vanes that are placed in the path of the materlal to be treated. The feeding ends of the vanes 23 are placed circumferentially about the cylinder as illustrated in Fig. 4 at 27, to impart a screw action to the material. The feeding chute 4 is so arranged as to depos t the materials well within the vanes as is illustrated in the dotted lines in Fig. 2. We have found that the indirect a plication of heat produces the most satis actory results, and that liquid, or gaseous, or powcred fuel will give the most economical operations free from operating troubles: An inner heat pipe 28 is disposed within the cylinder 12, and central thereof, the fuel being fed through a suitable burner head 29. No particular type of burner head is recommended, as there are many types adaptable for this character of service. he

fuel is supplied through feed pipe 30. In operations of this character, the material to be treated is fed into the treatin chamber at a-fairly low temperature and t e temperature of the mass will increase as the mass is fed along the treating chamber. Those volatiles that become gaseous at the lower temperatures will be liberated in the early stages of the treatment and as the temperature is increased other volatile substances will asify and be liberated. To permit of the rawing oif of these different volatiles within certain groups, we have provided outlet tubes with induction fans placed therein. The firstoutlet tube 31 having an induction fan 32 secured thereto, and a second outlet tube 33 having an induction fan 34:. The number of outlet tubes will depend upon the character of material being treated and the relative length of the treating cylinders. A seal is maintained between the upper and lower cylinders to prevent the escapement of the gases being liberated. One or more outlet tubes are also provided in the lower treating cylinder, as shown at 35.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as

it is susceptible of embodiment in various forms, all comin within the scope of the claims which f0 ow.
