OIL OR OTHER FILTER PRESS.
SPECIFICATION formingpart of Letters Patent N o. 67'8,858,'dated July 23, 1901.
Appliation filed August 11, 1900. Serial No. 26,546. (No model.)
To @ZZ whom t may concern:
Beit known that LPHILIBEET BONVILLAIN, consulting engineer, a citizen of the Republic of France, residing at Paris, 6 Rue Blanche,
in France,have invented certain new and useful Improvements in or Relating to Oil and other FilterPresses, ol which the following is a specification.
The present invention has for its object a ro box made up of metallic rings, which are placed one upon the other and having interposed circular wicks or filtering means, with or without metallic cores,.which oifer a large ilteringsurface. More particularly this box x5 is applicable for oil-presses, but it can of course be employed for any kind of filterpresses desired.
Generally ordinary boxes made with vertical bars have in practical use the inconvenzo ience that they only offer a very weak filtering-surface to the oil, which thereby meets a too great resistance to escape freely from the box. If in order to overcome' this difficulty the space between the bars forming the box is increased, even slightly, a great quantity of meal escapes with the oil, which spoils it.
Moreover, the meal thus carried away constitutes a loss, since it cannot be utilized except for mixing with material for the second 3o pressing.
In order to obtain with filtering cages and rings the same filtering-surface as with bags and the like, a very simple form of construction according to the present invention will be described with reference to the accompanying drawings, in Which-q Figure l is a vertical section through the box, taken on the line 5 5 of Fig. 2. Fig. 2 is a horizontal section on the line 6 6 of Fig. l.
4o Fig. 3 is a section, on an enlarged scale, of a ring; Fig. 4, a modified shape of a ring shown in section, on a reduced scale.
The box into which the meal to be pressed is introduced consists of a series of circular rings a ct, arranged one above the other, perfectly concentric, and fitted by means of a circular flange b on the upper face of one ring fitting in a corresponding recess c on the under side on the ring above. Each ring a is 5o provided with a Worked dat part CZ upon its under side and a similar surface on its upper side, so that when superposed the rings fit closely at d and e in a perfectmanner above each other. This arrangement has the advantage that the rings need only be Worked on their fitting faces. Each ring is provided on its upper side with a circular groove f and with radial cuts orv slots g g at equal distances apart. The groove f, preferably of rectangular shape,`Figs. l and 3, or of any other shape in cross-section, is provided to receive a filtering wick or packing 'h, which is fitted internally with a metallic Wire t of suitable shape, preferably ilat or circular, as shown in the drawings. These wicks areslightly compressed by the rings when in place, Each set of rings forming a box are arranged between two much thicker circular rings 7c 1,-with projections to receive clamping-bolts m m. The radial cnt s g g serve for the escape of the oil to the lteringwicks h h, a large ltering-surface being thus obtained, which facilitates considerably the passage of the extracted liquid. Moreover, the Wicks retain the meal, which cannot escape with the liquid. Moreover, the metallic cored in the interior of the wicks'serves to prevent these wicks from becoming t-oo hard and too thick under the internal pressure and maintain their Iiltering qualities. The wicks h h can be made of hairs, malil, felt, or any other convenient material, according to the nature of the meal to be pressed.
Having now particularly described and 'as certained the nature of this invention and in what manner the same is to be performed, I declare that what I claim is-V l. A filter-press comprising a series of rings and means for securing the same together, each ring being provided with a longitudinal groove and a Iiltering-wick in said groove, and also being provided with radial grooves adapted to permit the escape of the liquid to be filtered, substantially as herein set forth.
2. A filter-press comprising a series of rings and means for securing the same together, each ring being provided with a longitudinal groove and a filtering-Wick provided with a metallic core in said groove, and also being provided with radial grooves adapted to permit the escape of the liquid to be filtered, sub-n stantially as herein set forth.
3. In a lter-press, a ring provided with means for fitting and securing the same to other-rings in a series, and providedwitflia longitudinal groove, a filtering-Wiekin said groove, and a series of radial grooves adapted' to permit the escape of the liquid to be iltered, substantially as herein set forth.
4. In a filter-pressna ring provided with means for fitting and securing the saine tov other rings in a series, and provided Wtha longitudinal groove, a filtering-wick provided with a metallic core, in said groove, and a series of radial grooves adapted to permit the escape of the liquid to be filtered, substan-y tially as herein set forth.
