CHARLES TURNER. AND RICHARD E. SCHROEDEB, OF CHICAGO, ILLINOS, ASSGNORS OF THREE-FOURTHS T SAID CHARLES TURNER AND ONE-FOURTH TG SID RICH- ARD F. SCHREDEB, BOTH 0F CHICAGO, ILLINOIS.

. METH) OF EXTRACTING OLS FROM SOLIL To all whom it may concern:

FII

Be 'it known that We, CHARLES TURNER and RICHARD F. Sonnosonn, citizens of the United States, and residents of Chicago, lcounty of Cook, and State of Illinois, have vinvented certain new and useful Improvements in the Method of Extracting Gils from Solids,`otvvhich the following is a specilication, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to that method of extracting oils from solids, such as vegeta ble or animal mattei', in Which an oil solvent is employed, and which may include treatment of the material by hot vapors for thepnrpose of eliminating the volatile parts, andvparticularly for recovering by volatili- Zation and subsequent condensation the oil solvent which may be held in the material Vby absorption.

The obj ect of the invention is to simplify and expedite the Work and to provide for continuous operation upon material as it moves through the zones of action. 4

The invention consists broadly in passing the material through a c hztmber, or chan bers, in a practically loose and open state and introducing into the massthe oil solvent or the heating agent, the material be ing impacted at the receiving and delivery ports of `such chamber, or chambers, and thereby preventing the escape throughinese ports 01E-any part of the dissolving orheatin'g agent except so much thereof-as muy be .held by absorption.

lThe invention may be practiced by mea-ns of any apparatus which Will advance the material through the chamber, or chambers, Within which it is to be treated, retarding` its movement as it enters and leaves such cham ber for the purpose of impacting it iito a substantially impervious mass and Wh' fh includes means torintroducing the solvent or heating agent into the material at suitable stages. v p

One torni ot' apparatus suitable for practicing the improved method is illustrated in the accompanying' drawings, in which-- Figure 1, appearing in part on each ot' two sheets, shows a longitudinal, vertical section ot' the apparatus; Fig. 2, a vertical section on the line 22'of Fig. 1; and Fig.

3, a detail in perspective ot the section ot the apparatus within which the material to be treated. by the'solvent or heating agent.

The apparatus shown comprises a continuous tubular cylinder through which the material to be treated may be caused to travel at variable rates of speed through different sections ot the cylinder. The cylinder, as shown, comprises a receiving sec- `tion 10, into which the material may he introduced through a hopper 11, and which isv shown as inclosed by a jacket 12 into which steam may be introduced through a pipe 13,

for the purpose of freeing the material from moisture, the vapor. being permitted to escape through suitable openings; a section 11 having foraminous Walls and receiving the material from the section 10; a section 15 receiving the material from the section 14 and passing` it on to a section 16 having foraminons Walls; and a section 17 receiving the material from the section 16 and beingprovided with a lateral discharge aperture 18.

A shaft 19 is journaled in the heads of the cylinder and is located upon the axis thereof and is provided at the end with a pulley 20 by means of Vvvhich it may be rotated. Conveyor blades 21, 22 and 23, here shown as each formed of a continuous spiral, are

mounted upon the shaft 19 and located respectively Within the

cylinder sections

10, 14 a-nd`116. Choking nipples 24, 25 are preferably placed Within the cylinder intermediate of the

sections

10 and 14, and 15 and 16. The delivery end ot the cylinder may be cramped by mea ns of a valve 2G shown` as slidablv mounted upon the shaft 19 and controlled by a hand lever 27. The cylinder sections 14 and 16 are inclosed, respectively, Within tanks 28, 29, adapted to receive liquids discharged from the material.

The oil solvent may be introduced into the apparatus by means of a pipe 30, branching, as shown, at 31, 32, and entering the tank 28, each of the

branch pipes

31, 32 delivering to a plurality of pipes, as 33, 34 extending along the outer surface ofthe cylinder section 14: and opening intothe interior of this section throughapluralityof nipples` as 37, 38. A heating vapor, such as steam, may be introduced into the cylinder section 16 by means of a similar arrange` ment ot'r pipes, the main steam pipe being shown at 39 and one of its branches at 40.

i It desired, the shaft 19 may be trlbular and are included Within the cylinder sections lei and 16 are lreely perforated, as shown at fill, 45. A vent pipe 4C is shown as leading from thc clnu'nher of the tank 28 to the discharge pipe Il? leading from the tank 29,

this vent cf rrvingoil any vapors which may is treated by into the cylinder acciunulate and nihich it may be desirable to condense. A steam pipe i8 is shown as entering the tank QS), and serves as means 'for driving out any vapors which may accuinjulaie therein. pipe 49 leads from the upper portion o't the tank 29 for the purpose. oi conveying 'therefrom vapors which may be delivered to a suitable condenser.

finan apy'iarartus such as has been dcscribed, the material to be treated being delivered into the cylinder .section l0 is advanced therethrough, at such speed as may be desired, but before leaving this section is Well heated and practically freed from all water with which it may have been charged. As it leaves the cylinder' section l() it becomes impacted and moves slowly section lll Where it. is disintegrated and advanced more rapidly by the conveyor mechanism therein.` `While Within this cylinder section and in a practically loose state, it becomes charged with the oil solvent vintroduced through the pipe 3() and its branches, and this solve'nt with the oils are drained. through the apertures of tf inder Wall. into the tank 28 and com therefrom to vany suitable \receptacle. As the material issues from the cylinder section itis again retarded Within the cylinder s Walls. the l er supplemented, when such device it nt. by the choking nipple 25, and becomes so impacted or solidified that any vf )on which `may be present Within the confines ci me tanl-r 28 cannot escape therethrough, and they are prevented from escaping into the cylinder section l0 by the impacted mass ot material between that section and the section lli. .y

As the impacted rmaterial slowly enters the cylinder se' tion 16, it is disintegrated and more rapidly advanced through that section by the conveyer' mechanism It the vaporizing agent, preferably steam, which isldelivercd through the pipe and its branches.y Anyc the oil solvent which `may have beeny .heldmvithin the material by absorption is here vaporized :ion .l5-1 by the friction ot' the.

4subject ofour estesa and passes off through the pipe 49 to any suitable condenser.

The process is not dependent upon thcparticular apl'iaratl'ls herein shown a ud dcscribed, but may be practiced by any apparatus which provides 'For the continuous. or substantially continuous, inw-:cumul ol the material, its retardation and hnuaclng at cach side of the zones Within n 1 .rh il is to be treated hy the solvent or` vaporizing agent muy be acrmuplishcd bv any suitable means other than ille spiral con\'c\'cr. as. l'or example, a rcciprrwatuin' plunger. o1' (he process may be prariticeii by the use ol au apparatus so arranged that the material will become impacted by gravity. The advantages oi" the process are that the operation may be continuous, and requires very little labor. liurthermorc, the various actions may be easily regulated by varying` the rate of travel of the material through the apparatus and the quantity of dissolving;` and vaporizingg' agents uscd. The residue of thc solid material is discharged as a part of the.

process and without suspending` the operation.

While thc described method, so far as wc are at present advised, may be mosteconomically and advantageously practiced by givlin@ the material a continuous niovcmentfthc invention is, however, of suiiicient scope to include an operation in which the material 'may be allowed to como to rest.
