SSPECIPICATION forming part of Letters Patent No. 366,398, dated July 12, 1887.

Application filed October 11,1986. Serial No. ll ,830. (No model.) Patented in France September 37, 1883, No.157,738, and in Bolgium February 13, 1885, No. 67,862.

To all whom it may concern.-

Be it known that I, FERDINAND JOURDAN, a citizen of the Republic of France, residing at La Fare, in the Department of Bonclxesdu- Rhone, in said Republic, have invented a new and useful Improvement in Oil-Presses, (for which I have obtained a brevet d invention in France, dated September 27, 1883, No. 157,738, and a brevet dimportation in Belgium, dated February 13, 1885, No. 67,862,) of which the following is a specification.

The principal object of this invention is to provide for the extraction, without the aid of bags or mats, of the oil contained in the paste of olives or in that of any oleaginons grains, and in general of all liquids capable of being obtained by pressure from any solid bodies.

The invention consists in the combinations hereinafter described.

In the accompanying drawings, Figure 1 represents a vertical section of the apparatus; Fig. 2, a plan of the same, and Fig. 3 a side elevation of the same. Fig. 4 shows an elevation of the face of one of the filter-plates with which the body of the press is internally furnished. Fig. 5 represents a vertical section of one of the said plates. Fig. 6 represents a horizontal section of the same. Figs. 7, 8, and 9 represent, respectively, on a larger scale, an elevation, a vertical section, and a horizontal section of parts of one of the said plates.

Similar letters of reference designate corre sponding parts in all the figures.

This compressor has two press-bodies, A and B, preferably of a square section, and open at top and bottom, for permitting the discharging and recharging of one during the op era-tion of compression in the other. YVith this object the two press-bodies are secured or constructed close together side by side, and arranged to turn about a strong vertical column, O, placed between them. This column, forming an axle of rotation,serves, besides, with two other columns, D, to hold together the fixed upper and lower plates, E and F, of the press. The latter plate has constructed in the same piece with it the hydraulic cylinder F* of the press, of which the piston F effects the compression of the paste from which the oil is to be extracted, and the said plate has secured to its upper part a trough, G, into which the liquids are received as fast as they are extracted. The top plate, E, is large enough to cover one press-body, but to leave the other uncovered, as may be understood with reference to Figs. 1 and 2.

On that side of the column 0 opposite to the cylinder P and out of range of the top plate, E, there is firmly secured to the plate F a second cylinder, H, of smaller diameter than the first-mentioned cylinder, the said cylinder H containing a piston, H, for the purpose of discharging one of the press-bodies, while the piston F of the cylinder F compresses the paste to extract the oil therefrom in the other press-body. By this means the machine is made to do double the work of ordinary presses.

The rotation of the press-bodies A and B about the axle C to substitute one for the other is effected without difficulty, owing to the said bodies being supported on conical friction-rollers I, which run on a fixed circa lar way provided around the axle O.

The press-bodies A and B are preferably square. Their walls are provided internally with vertical grooves K, against which are applied the filterplates L, which dispenses altogether with bags or mats, in which heretofore the paste has been inclosed, the said grooves extending the whole length of the press-body, parallel with the direction in which the pistons work, and being open at the open ends of the press-body. it results from this that when the pulp is pressed the liquids pass through the filtering-plates, flowing down the vertical grooves K, provided in the walls, and falling into the trench G.

The filteri-ngplates L consist of three partsa plate, M, of iron, steel, or other metal, perforated, a special cloth or fabric, N, and a second perforated plate or series of metal strips, P, arranged as follows:

The plates M, of a mean thickness of about seventeen millimeters, are flat on the side which comes against the grooves K, and have on the opposite side a series of half-round grooves, 11, a, which are parallel with the grooves K of the walls of the pressbody, and which receive the cloth N, of horse-hair or other suitable fibrous material. Along the anglesbetween these half-round grooves the plate M is pierced with holes 0, of about five millimeters in diameter, serving for the passage of the liquid into the grooves K of the walls of the body of the press. the cloth Nagainst this grooved plate M, halfround strips of metal, P, adapted to the form of the grooves, are made to press the cloth therein by means of tightening-screws or rivets s s, as shown in Fig. 9. are also retained at a'distance apart of about five to six millimeters by means of transverse bars T, (see Figs. 4, 7, 8,) secured to their ends by means of rivets n.

In order to divide the residuum of the seed which is contained in bulk without bags in the body of the press into oil-cakes of any desired thickness, horizontal partition-plates R, of sheet metal, are placed in the press-box at suitable intervals within the filtering-plates which line the sides of .said box. By means i of these plates the residuum is converted into cakes without bags in as perfect a manner as when bags are employed to contain the seed in separate portions.

The operation of this press is as follows: While the piston F of the hydraulic cylinder F* compressesthe paste contained in the pressbody A, for example, placed above, and the oil or other liquid thus extracted passes through the filtering-plates L, to descend along the vertical grooves K into the trench G, the other press-body B, which has been filled with compressed cakes by the previous operation of extraction, is above the hydraulic piston H, which by rising forces out the cakes at the upper part of the body B, which has been uncovered by moving away from under the fixed upper plate, E. Then the piston Hdescends.

To compress The said strips I 'the press-body B the compression is completed in the press-body A. The piston F is then caused to descend, and the key S, which holds the press-bodies stationary, is withdrawn and the press-bodies A B are turned together to the extent of one hundred and eighty degrees (180) to bring the body B over the piston F and the body A over the piston H. Thekey S is thenreplaced, and the two press-bodies having been substituted one'for the other,the operation is repeated.

I do not claim a pressbody having vertical grooves in its sides; but

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, with a press-body having in its sides internal grooves, K, extending lengthwise from end to end thereof, of'filtering-plates constructed and arranged substantially as herein described-that is to say, composed each of a metal plate, M, having perforations O O, a clothlaid against the inner face of said metal plate, and metal strips P, fastened against said cloth to said metal plate opposite the spaces between said perforations, the so composedfiltering-plates being placed against the interiors of the side walls of the press-body, with the cloths and strips inward, as herein set forth. 4
