tween the lateral walls of the press`chambers while in a convex bend the pressure s relaxed. lf the coopera-ting walls of the press chamber be vertical with the lenible member horizontal, on a concave bend the chamber becomes narrower and inv section approaches more or less the shape of aninverted V.; that is the mouth is narrower than the bottom. Or it the chamber be V-shaped'in normal position, on concaving the flexible member the walls approach each other, and, if the curvature in the bend be on the correct radius, the chamber tends to become obliterv' ated and the coperating opposite walls propressure on the contents duce al right-line of the chamber;

The flexible member carrying the press 4chambers vmay be a traveling belt, or beltlike member, traveling over rollsy in the conoperation, `but the closeness of the caving1 pino between belt 'and roll does not, as

inl the ordinary belt-and-roll press, have anything to do vwith the -eed or with the pressing operation directly, and the pres- Y as desired since there is nomateriai between them. '.Ihe face of the roll Vindeed in sachA sure between belt and roll is not directly exercised upon the material in the chambers; it is indirectly exercisedin lessenmg the vollsure between belt and roll may be as high unie oithe chambers and of the containedl material. For mechanical reasons, the mem ber carrying these press chambers is preferably a belt o r belt-like structure, Iiexible enough to be carried around rollers orv the like adapted to give it alternating conca-ye and convex bends. It may beabelt carrying" 'projecting transverse cross members such as bars or slats forming press chambers between them. @r the transverse members maybe carried at theirends by a .p air"o, narrow belts, sprocketchains or the like', or i be simply linked together at their ends.

Such abeltlike `member may be carried Y aroiind-a-'pluralityfo ,rolls with its presser face alternately concave and convex, the material being fed into the chambers in a 'co-nvex bend when the chambers are opened, Y expression performed during the concave 5 bend when they are narrowed and the material subsequently removed when the chambers open out subsequent to the concaving. Pressing should be in a plurality of stages, the belt being given a number of successive Vconc`ve bends. This allows the cake to assume new lpositions prior to ai re-pressing. Between pressures, sprays of water,.steam or oil may be directed on the expanding and porous press cakes. lThe chambers'may be of such shape and dimensions that they may be-lled'vwhile the fiexible member is in a .attened-.positionf After the final pressure, the Vbelt-like member may be passed around la roll of such radius as to cause the filter 20, cloth", to straighten out' to form a fiat surface from which the c ake may be easily scraped o, Where the belt-like member turns in a -vertical plane, the bags of the' filter -cloth in the chamber when the presser I face is uppermost, may turn inside out and hang down whenthe presser face is on the I lower turn.

In the stated structure, it will be obvious that while the pressingis performed on' a 30 Series of'successive separate small cakes, yet

the structure as a'whole is continuously op- .erating in the sense that material is always 1 being fed to and removed from it.

In another application, Ser. No. 514,851,

filed Aug. 27, 1909, I have described andclaimed the stated method of expression and have also claimed' broadly' apparatus deigned for use in its performance. In said pplication, 'I have described and shown 40 several types. of apparatus and have claimed specifically a type wherein the fiexible belt' or chamber 'is mounted in a.revoluble housing vadapted for rotation aboutan included axisy whereby centrifugal force is caused to act upon the materialto be expressed. The present application is devoted more specifi.- cally to a type wherein the exible belt or member' is mounted in a stationary housing, certain embodiments' of-,said type being shown 'but ,not specifically claimed in said 'acknowledged application. As stated the shape of the cross members modifiest-heir action somewhat. lVith rectangular slats or bars in a horizontal-position of the belt the press chamber is vertical walled, on a convex bend is V-shaped and on a concave bend may become the shapeof an inverted'V. With slats or bars havinga' section of a truncated triangle, a better pressing action is secured since with a concave' bend on a curve of the'proper radius, the press chamber will lessen in breadth symmetrically. A still better operation is obtained vby using curved cross pieces. The

cross pieces mav be crescent-shaped in cross' pressure for,v a period' totaling 24 minutes.

section. If the bars are mounted pivotally at their ends, on parallel sprocket chainsa desirable structure is obtained; and particularly where such bars are curved or crescentl shaped.- The materia-l falling into the bot- 7G tom of' the. bag between the presser members will tend topush the bars apart near the bottom and with the'pivotal mounting they .will concomitantly approximate near the top, giving the pressure first near the top 75 and also"tending"te seal the chamber somewhat near the top. It is better to mount one of' suoli a pair of cooperating -bars pivotally and the other fixedly, as regards the carry ing ofl lateralv linked elements.

The cross members or slats may be made of any suitable material, such as wood, iron, steel, brass, etc. Ordinarily they are best made of steel. F or special purposes, such as the pressing of grapes, they maybe made of, or coated with, incorrodible metals such as aluminum or copper, aluminum 'being the best for grapes. .They are best perforated to increase the area for -the escape of' liquid, and while they' may be individually pro- 90 vided with a filtering layer, it is better to 'provide a loose filter cloth. This cloth mayweight of the belt-like member may -do much 100 of the pressing.' The simple sag of a long flexible member! may be suflici-ent to produce the required concavin'g for exerting pressure in the press-chambers. The use of rolls or wheels for producing a positive concaving is, however, much more desirable'. In any' embodiment, the pressing action between adjacent presser members is lateral. In eEect it is a sort of toggle action, and other forms of toggle pressure maybe substituted, though 11o less effectively, for the described alternate bendings of the flexible member. A belt may, for example, carry alternate fixed and movable vertical members forming press chamberstherebetween. By providing a series o f such alternating vertical members with a toggle joint between each successive pair, and then providing a cam or toothed' member adapted to press upon this toggle joint, materials in the press chambers may be submitted to a succession of .consecutive alternating compressions and relaxations of pressure. Vith such a structure, giving a plurality of successive compressions on'the vsame cake, say eight, with the length of the belt-like member and the speed'of travel' so adjusted that .in each compression the material is under pressure. for'three minutes,

obviously the material will be submitted to the" expression of liquid,` vin a way, pressure `and time arer'eciprocal, the longer the pressure the more llquid being removed. In

this-structure' any length of 'pressure can be 6 given while still making the operation con' tgmudus. It ismerely amatterof lengthenling the flexible member so as tofget as many successive compressions asl may be desired. vThis method of loperatinghas --a further '10 great advantage that while the total time of f the same apparat-us; certain elements being.

In the showing of Fig. 1f, element 1 represents as a whole a suitable framework comprising horizontal beams 2, `standards 3 and stay pieces 4. Mounted in this'framework are a series of wheels or sprockets. 5, over and under' which passes: a iie'irible belt-like vmember indicated 'as a w`holembyf7 and comprising a series oftransvers'e crescent-shaped cross pieces or presser members 8, thesecross, pieces being alternately pivotally mounted and rigidly. mounted (see Fig. 7). The 'Hexible member is looped over and under .the wheels in such a manner as to give it, considered as a whole, a succession of alternating 'concave and convex bends on the upper or presser 'fa-ce. vAta point prior'to the iirst concave bend and ata" point where chambers ofi-'the belt-like member are in an open po- .-si'tion is mounted a feeding means 9 for sup.- 55 pying-material to be pressed. At anothera bucket conveyer. Y '26 travels up one side of this housing and "point-above a convex bend, where the presser members open out, is mounted nozzle 10 through which steam, water, oil or other fluid may be supplied tothe expanding press cake. At' the farther en d f the apparatus the belt-like member passes'over wheel 11, and the press chambers are opened out t0 discharge into conduit 12 for removing expressed. material. Liquid expressed from the material is received by pan B. 'For purposes later stated, each alternate presser member may be provided with a retaining hooked member or keeper 13. Between each pair of presser members is mounted a piece of filter' cloth-14. -At the end of the apparatus in the `bend given by'wheel 11 these cloths,

4which are bag-l'ike-in-the concaving bend,

open out to lpermit a ready discharge of material. The return loop of thev belt-like member passed under wheel 15 and through a pan-like member 16., wherein the cloths' Imay be washed. In this passage 'the bags hang downwardly, permitting a 'good washing. The' showing in Fig. 2 is of the same "structure, but'- it discloses more clearly the relation between the wheels and the belt-like 'memben' As'will be noted, forthe sake o'f strength the belt-like member is provided with cross rods 17 having prolongations 18 which are for the purpose of engaging the wheels and riding thereover and thereunder.

These wheels may be provided with coperating notches 18a. Motion is given to the belt-like member by drive member 19.- In Fig. 3 no special means are shown for lproducing theconcave curvature-of the belt, the

natural sag' caused by the weight of the belt-like member producing the necessary concave bend and compression. The presser members provided in this form are shown as cross slats or bars" 20 of a'crossscction l -approximatelythat of a truncated triangle '(see Figa-12).A In order to allow this sag to produce the full concaving in the upper loop the return loop is supported on runway 21 which engages the pins- (18). InFig. 4 the belt-like member is -shown provided with cross pieces V22 also having'a section of the general form of a truncated triangle. The belt-like member is shown as carried by rolls 23. In a concave bend roll 24 operates to yseal the mouths of the press-chambers between 'the slats. In Fig. `6, a structure like that of.Fig.1 is shownmounted in a vertical housing 25,' and built in a general way like The belt-like member -by the'use of a roll or wheel 29, in spring pressed bearings v30. The liquid expressed in concave curvature falls upon plate 31 and is taken.. 'b3 gutter 32;

The solid matter `is removed through hopper 33. i

In Fig. 7- is shown in more detail the crescent-shaped ypresser members of Figs, 1, 2 'and 6, as well as the llnked carrying member which together' with these cross pieces constitutes the belt-like element.' Members' l 34, linked .at 35, are each provided with a lo. as at 3G, while the other is pivotally mountperforated as shown at 38 F 1g. 8 discloses an alternative method of pair of crescent-shaped cross piecesy (8% One of these cross pieces is ixedly mounted ed as at 87. .The -bag-like filter-cloth member -is between the ixedly mounted and swingably mounted coperating members.

YAs will be seenv by an inspection of these members, to the left of Fig. 7, thefweight of the material in the bag tends to swing the pivotally'mounted member against the top of the other, thereby-forming a seal at the top. These crescent-shaped members are (see Fig.- 5).

securing a lateral pressure in press chambers carried by a belt-like member-without the concaving and convexing' o'f the previous figures. In this showing a belt-like member 3S) is provided with a succession of alternating fixed members 40,' and movable members 41, there being a press chamber between the movable member and 'the fixed member, carrying a bag of textile material 42 therebetween. As shown, there are two layers of textile heavier and designed the other is of closer meshed material. As these members travel along with the beltlike' member toggle members 43, provided '.vith projecting arms 44, meet and are engaged by'roller 45 producing a lateral pressure within the press chamber. The operation of F ig. 9 is the same, save that the toggle member projects above the general -ljeyel of the press chambers and is adapted to'be engaged by member 46.

In Fig. 10, the cross pieces are shown, as

being of generally rectangular cross section and as carried by linked members 47, which space them somewhat apart. Over these cross pieces are two layers of textile matestrong textile material and close meshed textile material. As shown in Fig. 10, with this arrangement when the belt-like member is in a fiat position the chamber therebetween is of rectangular cross section. On aeoncave bcnd, as shown in Fig.. 11, the

two cross pieces come together at the top.

and form a seal for the press chamber at that point. In this operation the press chamber has the general shape of aninverted V. This structure is desirable for many purposes, since wet materials fed into the bag-like element accumulate lat its base, giving a body therein which is thicker at the base than at the top. With the pres-sgr material, one being for strength, while,

rial 4S and 49, which are respectively of elements forming a chamber of an inverted V-shape the pressure may be proportionate to the thickness of the material Within. such chamber. In the. structure'shown in Figs. 12 and 13 the cross pieces have sides at an angle suiicient to give a substantially par: allel walled chamber in tion, as shown in Fig. 13.' When thefbeltlike member is convexed, with a proper length. of Vtextile material, such textile ma.- terial may be as shown in Fig. 14, drawn flat, thereby allowing the press cake therefrom. In Fig. 15 is shownI diagrammatically, a pair of presserl members which instead of being crescent` shapel as in Fig. 1, etc., are substantially straig it. One of these Ipresser members .50' is rigidly mounted as at 51, while the other. 52 is swingably mounted as at 53. This allo'ws the same sealing of the press chamber at the top.

in F ig.1, the material fed from 9 goes beconcave bend by the next rotary member 5, 1 00V as shown more clearly inFig. 7. With a proper curvature of the two crescent-shaped members a -right line lateral pressure is prp'- duced between them. The expressedliquld'- flows out through the bottomof the 'bag and through its sides and the perforations v38. Still passing forward to the left the material is opened up in .a convex bend'and may be showered as by 10 with Water or oil, or steamed, as may be desired. The liquid fiowing out in a concave bend is received by pan B. Passing forward stlll to the left A the belt-like member is given as-.manymore concave bends as may be desired vto givel the total time of pressure; Finally, in passing over the end wheels ofthe'series the cloth is opened out and the material tumbles off it int-'0 the hopper 12. Passing downward and to the right the belt li ke4 member is carried into a layer of water in -pan 16 and the bags which are now depending are washed. The keeper 13 serves to restrain undue swinging of the swinga'bly mounted cross member.

In Fig. 3 the `sag of the upper loop of the belt produces the 'necessary concave curva`4 ture and `the Vpressure between transverse presser members 20. In the apparatus of Fig. 4 the structure is generally like that of Fig. 1, but the presser members in lieu the pressing posi- In the operation of the structure' shown y tween the cross pieces 8, While the belt-like l Pass- A of being crescent-forrnecl-and swinga le are -lixedand have a lsection likef'rthat of a truncated' triangle.
