KENNETH EDGAR CLAYTON-KEE'NEDY, OF NEW YORK, N. Y., ASSIGNOR '10 AMERICAN HYDROCARBON CO. INC., A CORPORATION OF DELAWARE.

APPARATUS FOR EXTRACTING VOLATILE MATTER.

Application filed May 26,

machine utilized in accomplishing the re- 1o sults above mentioned.

It is the purpose of my invention to prevent caking caused by heating the particles of finely divided coal or other material used thereby assuring a more even and uniform heating of the'material than heretofore obtained and create a. machine of greater capacity and efiiciency. Other objects will be apparent from the development of the construction and description.

In accordance with my invention I place in the heated cylinder containing the carbonaceous material a tumbler or agitator which will agitate and disturb, as well as fall upon and break up any agglomerated lumps of material. The advantages of such a device will be obvious when it is .considered that heretofore only disturbing baffles-or fins secured to the cylinder have been used.

Further features of my invention will appear from the following description taken in consideration with the drawings and the appended claims:

Figure 1 is a side elevation of a machine embodying my invention.

Figure 2 is a sectional view taken along 2'2 of Figure 1.

Figure 3 is a perspective view of the tumbler or agitator. I

I have illustrated my invention as applied to the conventional apparatus as indicated in Figural wherein 1 is the inclined rotating cylinderin which material to be treated is heated. The material is fed into the cylinder through the hopper 3 where it travels gradually down the length of the cylinder by the action of gravlty aided by rotation of the cylinder until the volatile substances have been driven out due to application of heat. The spent material passes through the discharge end 5 while the gases pass "out through discharge 11 by means of a pump 13, are condense 1n the condenser 15 and thereafter collected insultable containers.

vanes I have cut openings 31, 33 arranged regular contours suchas sharp teeth or the rial.

1926. Serial No. 111,712.

Heating may be accomplished through the medium of molten lead 7 which is'kept in a molten state by means of burners 9'or by any other suitable means. The usual drivmg motor is indicated at 17 for rotating cyllnder 1. It is understood of course that the cylinder and discharge ends are sealed agalnst entry of oxygen by, sealing the ends from the outside atmosphere.

The above brief description merely outlines the conventional apparatus and it has been found that there is a strong tendency for the particles of material to adhere, agglomerate and cake when heated in these machines thereby destroying the ideal condi- 7 tlons necessary to assure uniform and rapid heating of allthe particles of material.

To overcome this caking I find it-convenlent to place in the cylinder a tumbler or agltator 19. This tumbler is substantially 7 the same length as the cylinder but smallerm diameter so that it is capable of tumbling around in thecylinder. This tumbler is merely placed within the cylinder without securing -1t in any manner except to prevent the tumbler from sliding axially out of the cylinder by placing a spider 21 in the discharge end of the cylinder or by holding with a chain from the upper end.

As a preferred form I have shown this tumbler in Figure 3 as being formed of four vanes 23, 25, 27, 29, substantially at right angles to each other intersecting at and extending from a common axis. Within these in relatively staggered position for the purpose of allowin any material picked up by, the vanes to si' t through to the bottom of the cylinder.

The design of the tumbler may be varied to meet the demands of a particular material to be broken up, for instance, there may be three vanes or of star formation, or the edges of the respective vanes may have ir- 10o vanes may be formed of a corrugated mate- The tumbler is preferably of some heavy material such as iron or steel in order to'have sufficient mass to crush the carbonaceous material and also to withstand the operating temperatures.

In operation themachine functions inthe following manner. The cylinder containing the carbonaceous material and the tumbler is caused to rotate by means of motor 17 Due to the friction between the vanes, the material and the inner periphery of cylinder 1 tumbler 19 is carried up with the wall vthe rotating cylinder until a certain level is 5 reached whereupon the tumbler will dro upon the material and break up an oak portions. Duringthe movement of the tumler, the vanes will also carry some of the material u on their surfaces and this inaterial will si through openings .31, 33 and be re-distributed throughout the cylinder. Each time the tumbler reaches a certain level it 'will drop down upon the material and so the cycles will be re eated maintainin material in'a finely divided and distri state.

the uted intersecting in a common axis, said .vanes having openings therein arranged in staggered relationship,

In witness whereof, my signature.
