n To all whom it may concern,.-

Be it known that I, BENJAMIN EMILE GAS- QUET, of Castres, in the Republic of France, and a citizen of the Republic of France, have invented certain new and useful Improvements in Filters, (for which patents were obtained in the following countries: in the name of Benjamin Emile Gasquet in France on the 2d of October, 1886, No. 178,832; in the names of Benjamin Emile Gasquet and Alfred de Gaulne in England September 20, 1888, No. 13,625; in Italy `September 22, 1888, Vol. 17, No. 308; in Spain September 17, 1888, No. 8,702, and in Portugal September 20, 1888, No. 1,289,) of which improved filter the following is a specification.

This invention relates to an improved construction of iiltering apparatus adapted to the iiltration of wines or any other liquids.

The invention consists in the construction and combination of parts and details, as will be l'ully described and set forth hereinafter, and finally pointed out in the claims. y

In the accompanying drawings, Figure 1 is a plan of the apparatus after removal of the cover, showing a iiltering-pocket in position. Fig. 2 is a sectionalelevation taken on the line :c of Fig. 1, but on a larger scale. Fig. 3 is a sectional plan, taken ou the line y y of Fig. 2, of the central part of the apparatus. Fig. 4 is an enlarged vertical radial section of a portion of the filter, showing portions of two cloth pockets, a corrugated wirecloth plate between said pockets, and rings for holding said pockets.

Similar letters of reference indicate corresponding parts.

A is a receiver formed of two timber frames a a and copper plates b b', the latter tinned on their inner surfaces and fixed by woodscrews c c to the frames. The two frames are held together by bolts d, which press them firmly one against the other, the tightness of the joint being further assured by a rubber packing e.

A distributerD is disposed in the center of the receiver A and serves to distribute the water to the iiltering-pockets within said receiver. This distributer comprises a central cylindrical chamber B', radial distributingchambers B2, surrounding said cylindrical chamber, and a-series of superposed rings E, surrounding said distributing-cliambers, said rings being provided with horizontal slots l. A series of filtering-pockets F is disposed within the receiver around the distributer, the inner edges or mouths of said pockets being clamped between the rings E of the distributer. The upper part of the cylinder j', which divides the inner chamber B from the radial distributing-chambers B2, isprovided with an internal screw-thread in its upper part and with perforations z' in its lower part, which pcrforations establish communication between said inner chamber and the radial chambers, and said cylinder is also provided with radial wings g, which separate the distributing-chambers one from another. The bottom of the distributer B is closed by a plate 7L, which is brazed or otherwise fastened to the cylinder f, and underlaps the inner edge of the plate b. The top of the distributer B is closed by a cap C, which is provided with a central downwardly-projecting externally-screw-threaded tube C', which screws into the upper end of the cylinder f, and with a nut j, by which the cap is screwed into position. The upper end of the pipe C is internally screw-threaded to receive a supply-tube. A three-way cock D, having the branches K K K2, is shown as connected with said pipe through its branch K, the other branches being adapted to receive supply-pipes.

Annular corrugated wire-clothplates G are disposed within the receiver between the textile cloth` pockets F and serve to separate said pockets from each other, forming intermediate pockets between the pockets proper F. The depth of the corrugations of the plates is equal to the thickness of one of the rings E or thereabout.

The textile filtering-pockets F are preferably composed of twilled cotton cloth. Each pocket has a'ccntral circular opening of the same diameter as the internal diameter of the rings E. The cloth of each pocket is folded at the outer edge thereof, and the inner edges m are separated at a distance equal to the thickness of one of said rings, the upper edge of one pocket being clamped jointly with the lower edge of the pocket next above between two of said rings.

H H are cocks provided for the purpose of drawing off the liquor in the receiver A.

The apparatus described above is erected in the following manner: The two frames a et being detached, the first operation is to place a reticulated corrugated plate G upon the bottom plate b of the frame a', upon which plate the cylinder f will rest. After a ringE has been placed between the two cloths m m of a pocket F in such a way that the edges of the central circular openings in the said cloths coincide with the inner face of the ring, the said pocket is laid within the frames a upon the bottom reticulated corrugated plate G. The cylinder f is at the same time set up within the ring E, the projections of the webs g, radiating from the said cylinder, bringing them in touch with the inner face of the ring. A second reticulated corrugated plate G is next placed upon the last-mentioned pocket F, and then a second pocket, with its ring, is laid in the same way as were the first pocket and ring. In this way the laying of annular reticulated corrugated plates, pockets, and rings is proceeded with until as many members as it is intended the apparatus shall consist of are in position. Fig. 2 illustrates the use of seven filter members. A reticulated corrugated plate is laid on the top, the second frame A placed in position, and the bolts d screwed lup until the joint between the frames is tight.

The part C is fixed next, its iiange being thereby brought to bear upon an iron ring I of the same internal diameter as a ring E, and which is strongly brazed or otherwise joined to the top copper plate h. As the nose of the flange C is screwed down, the rings E are in consequence of the pliability of the copper plates closed toward each other.

The apparatus is now ready for use as soon as the cock D has been fixed. The method of working it is conducted as follows: The cock D is coupled by the nozzle K to a rubber tube adapted to establish communication with any vessel chargedwith the liquor to be filtered and standing at a higher level than that of the apparatus. When the cock is opened, the liquor flows into the chamber B and out of it through the holes 'L' into the radial distributing-chambers B2, and thence through the slots Z in the rings E into the pockets F, which touch each other, whereupon the pockets become distended against the annular reticulated corrugated plates G. The liquor thence passes through the textile material of the pockets F into the intermediate pockets or spaces F between said pockets proper, and thence through said spaces to the opposite ends of the receiver. There are therefore provided, by the distinctive construction described above, a large number of passages, along which the liquor flows away into the empty spaces p p provided around the pockets, whence it is drawn off through the cocks H.

The process of filtration will be conducted free of all atmospheric presence, for when the air has been once expelled through the controllable openings R provided at each angle of the receiver-cover no more air can then enter, inasmuch as the apparatus is full of liquor all the time it is at work.

If from any lpeculiarity in the arrangement of the existing plant it is not practicable to charge the filter automatically in the way described above, recourse must be had to a pump. For the purpose of obviating the irregularity ordinarily characteristic of a pump-supply, the third nozzle K2 of the cock D is coupled by a rubber tube to` a tank placed at a definite height. The pump-delivery is coupled to the nozzle K and the excess from the said pump passes into the tank, which has the effect of tending to produce a constant pressure.

Having thus described my invention, I claim asn ew and desire to secure by Letters Patentl. A filter constructed with a series of filtering-cloths, corrugated metallic reticulated plates interposed between said filteringcloths, a central inlet-chamber having apertures communicating with the pockets formed between the filtering-cloths, and a casing containing said filtering-cloths, plates, and inletchamber, all combined substantially as set forth.

2. A filter composed of a casing, a series of filtering-cloths in the same and provided with central apertures, a series of corrugated metallic reticulated plates between the filteringcloths, a central apertured cylinder composed of rings, between which the inner edges of said cloths are held, and a perforated and winged chamber in said cylinder, all combined substantially as set forth.
