IMPROVEMENT IN APPARATUS FOR REMOVING OIL FROM VEGETABLE AND OTHER MATTERS.

Specication forming part of Letters Patent No. 112,389, dated' March 7, 1871.

I, THOMAS SIM, of the city` and county of Baltimore, Maryland, haveinventedan lmproved Apparatus for -Removing Oil from Vegetable and other Matter, of which the following is a specification:

Nature cmd Objects of the 'Invention My invention relates to an apparatus in which a series of inclined vats is employed in connection with a single evaporating apparatus.

It is found by experiment that bisulphide of carbon penetrates the meal, and that the combined chemical and oil `flow off with greater freedom in inclined vats than in vertical ones. By inelining the vats the meal is also caused to descend freely to their bottoms in the act ,y of discharging` without liability of caking or adhering on their sides.

` A third advantage of this arrangement is that it affords greaterrooni around the tops of the vats for feeding the Same, while theirl lower ends are brought in closer proximity to the separator.

The vats are arranged around the upper surface of the evaporating-tank and supported in any suitable manner, so that their charges, after being freed from oil, may be successively y introduced into saidevaporating-tank and the vat relled with meal.

Description of the Acconwfmying Drawing.

Figure l is a central vertical section (partly in elevation) of the apparatus, the screw-conveyer, as shown, being larger than is employed in practice. Fig. 2 is a top view, a portion of .the upper tloor for sustaining the vats being removed. Fig. 3 is a vertical section of a vat on a line transverse to Fig. 1.

General Description.

une

and four feet in diameter, each vat would be about eight .feet high and three feet in diameter, though these relative proportions are not essential. Each of the vats A has a pipe, D, near its base, for the admission and withdrawal of the liquid bisulphide, the oritice being provided with a diaphragm and a pipe, E, near the top, for the discharge of the mingled oil and chemical, the exit of the meal therewith being prevented by a diaphragm, E, near the top of the vat, but below the discharge-pipe E. This diaphragm is supported in position in any proper manner, and has an aperture, 7L, covered with a meshed cover, so arranged as to be opened and closed simultaneously with the disk which closes the feed-aperture F in the top of the vat, through which meal is introduced. Each vat has also at bottom, extending through the tube O, andnearly corre- .spondin g thereto in diameter, so as to revolve freely, a widely-dan ged endless screw, Gr, journaled and rotated in any convenient manner.

A screw of three inches in diameter will suffice to discharge a vat of the dimensions named above.

The descending branch C of the tube G is provided with a faucet, c, by turning which the meal is permitted to pass into the tank under the impulsion of the screw Gr.

The evaporatingtank B may be similar to that described in patent to E. S. Hutchinson of July 26, 1870, in which steam is introduced, through pipes on one side of the tank, within a series of hollow shelves or ledges, and discharged, after condensation, at the other side,

while the meal is passed between the shelves and gradually forced downward by a series of arms rotated by a geared shaft.

I do not claim this form of vaporizing-tank as my invention, nor do-I confine myself thereto in practice, as my vats may be adapted to other descriptions of tanks.

` Operation.

The vats A are successively filled with meal, and the liquid bisulphide of carbon, ori-equivalent, admitted thereto, permeatin g it, and nally ilowing off at top through the pipe E. When it is found, by the bisulphide flowing oft clear, that the oil is thoroughly extracted from the meal in the vat where the operation was rst commenced, the supply of liquid is eut ott' and the meal drained. The faucet c of the tube C is then turned and the sereW G revolved, so as to rapidly withdraw the partiallydry meal from the Vat, allowing it to fall into the heated tank B, Where, during its downward passage to the discharge-aperture I, the bisulphide is vaporized, escaping through a pipe near the top of the tank and being conducted to a chamber, where it is reeondensed for future use.

It may be proper to remark that the Whole of the meal is not withdrawn from eaeh vat at each operation. That part which was at the top of the charge having become elotted or eaked is allowed to remain, and is disintegrated by the aseendin g current of liquid which is admitted when the vat is 4charged anew. lt is then Withdrawn with this next charge, a new cake being formed on top, as before.

. Claims.

I claim as my invention- 1. The inclined vats A A, 86e., constructed,

arranged, and operating substantially as and v for the purpose specified.

2. The combination and arrangement of a series of inclined vats, as herein described7 with an e\f*aporatingeylinder, substantially as and for the purposes set forth.
