Specification of Letters Patent.

Patented Nov. 27, 1906;

, Application le September 6.1905. S'erialvNo. 277.241.

T0 all whom t may concern:

Be it known that I, FREDERICK OLIVER. a citizen of the UnitedStates, residing at Portsmouth, in the county of Norfolk and State of Virginia, have invented a new and useful Press, of which the following is a specification.

This invention relates to presses for eX- tracting oil from various materials, and has for its rincipal object to provide a novel fp press of the continuous-belt type wherein the straining elements are backed throughout the whole of the pressurearea and the backing elements are adjustable in order to increase or decrease the pressure on the material.

A further object of the invention is to provide a press of this t e in which the strainer-bars are so arrange as to form continuous rims or flanges at opposite sides of the filter-belts forthe purposeof reventin es of sai the escape of the Oil from the Si belts.

A still further object is to provide a pressfeeding device of such construction as to insure a practically uniform feed of material to the press elements; y l

A still further object ofthe invention is to pro vide a press-feeding device in which the material to be pressed is congealed and delivered in the form of a lm of relativelv solid material to the press. f

A still further object of the invention is to provide a press-feeding mechanism in which 4the oleaginous material in Huid form is congealed and delivered in the form of a iilm of relatively solid material to the press.

With theseand other objects In'view', as will more fully hereinafter a pear, the invention consists in certain no ve` features of construction and arrangement of arts hereinafter fully described, illustrated 1n the accompanying drawings, and particularly pointed out vin the appended clalms, it being understood that various changes in the form, proportions, size, and minor details ofthe structure may be made'without departing from the spirit or sacrificing any o the advantages of the invention. y

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of a press constructed in accordance with the invention. Fi .2 is a vertical sectionof the same, on an enlarged scale, on the line 2 2 of Fig. 1. Fig. 3 is a detail respective view of a portion of the press, slowing the side guards of the compression-belts. Fig. 4 is a transverse sectional viewgof a portion of a press, illustrating a'slight modification of the invention.

Similar numerals of reference are ernployed to indicate' corresponding arts throughout Athe several figures of the rawmss- The working parts of the press are mountedin a suitable frame 10, at the bottom of whichis arranged la tank 11 for the reception of the expressed oil. This frame has bearings for the'reception of shafts 12, 13, 14, and 15 and is further pro vided with adjustable bearings 16, 17,` 18, and '19, arranged, respectively, for the reception of shafts 20, 21, 22, and 23, all `of-said-shafts being disposed in parallel relation.

The shafts 12, 13, 20, and 21 are provided with drums 24, which arel arranged in pairs, one pair carryin a filter-cloth 25 and the other a filter-clot A 26, these,` cloths beingin the form of continuous belts and thelower run of one and the upper run of the otherbeing so arranged as to form al compressionspace of` gradually-decreasing hei ht from t e entrance to the discharge'end, t e material fed between these cloths bein subjected to constantly-mcreasing pose of extracting the o1 The shafts 14,15, 22, andY 23 are provided p passage of the oil, the spaces between the slats being angular in form, narrowest at the top and wldest at the bottom, so as not to interfere with the flow of the oil after its passage through the cloth. The o posite ends of the slats 31 are provided wit blocks 32,l

that preferablyare provided with intertting lugs and recesses in order to form practically continuous rims at each side of the lower compression-belt, and .thus prevent the flow of any oil from the side of the belt. The upper run of this lcompression-belt is supported y a series of bars 33, which rest on transversely-disposed bars 34, the opposite ends rressure or the Ypur- IOO rigidly secured to the frame, so that the Whole length of the upper run of-the belt is employed as a compression member.

The up er sets'of sprocket-wheels are ar-y i ranged within the lines of the first or lower ond compression member.

. discharged in a set and are connected by link belts 36, and said link belts serve as su ports for transversely-disposed slats 37, w ich form the secsupported in operative position by bars 38, that are held by transversely-extending bars 39, the opposite ends of which project beyoud the opposite edges of the belts, and said ars 39 are connected to the frame by bolts 40, which may be adjusted in orderto alter the degree of compression exerted on the material and at the same time to alter the angular relation of the compression-surfaces.

The up er slats 37 may be arranged to fit very close y together in order to prevent the escape of oil at the top, or they may be slightly spaced, so that the oil may iiow freely through the upper filtering or straining belt and pass od from the .sides of said belt and fall to the tank, or, if necessary, the belts may be. slightly inclined in order to facilitate the discharge of this oil. l

It will be seen that any material placed between the belts will be fed forward between the compression-surfaces, and as the latter gradually approach each other toward the discharge end of the machine the material will be subjected to gradually-increased pressure, so' that the oi pressed and the magma or residuum may be j ractically dry condition. Th adjustable sha t-bearings ermit the taking up of any slack in either t ie compression or the filtering belts, and by adjusting the bolts 40 the an ular relation of the belts may be altered an the degree of compression made to suit the material being treated. 4In

, order to further support the link belts, addi- *tional s rocketfwheels 41 may be laced between t e end wheels, as shown in ig. 1.

. this portion The apparatus is of considerable value in se arating stearin from cotton seed and other oils, lard, and tallow. ln carrying out of the invention the raw oil as expressed vfrom the seeds or delivered from the rendering-tank is fed to a tank/43 in iiuid form. Arranged above this tank is a revoluble cylinder 44, in which cold brine or other material is continuously circulated, the cylinder being chilled and its surface dipping into the iiuid oil of the tank 43 becomingcoated with a iilm of congealed oil and stearin, which is carried up and fed through the press, a suitable scraper i6 being employed to remove the material from the cylinder. lt is found in practice that when used in this way These slats are' will be yfully ex-` the stearin in congealing will hold the oil mechanically yand in passing through the press the oil will be forced. out and the stearin will pass from the end lof the press free from the oil and in condition for use. A

The structure of the machine may be slightly modified, one of such modifications being illustrated in Fig. 4, whereinV a single filtering-belt 19 is employed.` This belt is much wider than those shown in Figs. 1 and 2 and is so arranged that its edge may be,y

folded and overlapped in order to form a continuous cover around the material being pressed, provision being made for opening the belt for the insertion of the material and afterward folding the same prior to its passage between the compression members. Where a belt of this type is em loyed, the transversely-disposed slats whic form the compression-surfaces are referably so arranged as to yield or bow s ightly, so that the main body of material will be retained at the center of the belt, as shown in Fig. 4. This structure may also be employed inV connection with the two belts shown in Figs. 1 and 2, and in this case the edges of said belts will be held in close contact and prevent the esca e of oil from the sides of the press. The be ts and compression members may be further arranged at an angle to the horizontal in order to permit greater freedom of dischargev .of the oil.

Having thus described the invention, what Jis claimed is-- 1.111 a press of theclass described, a pair of slatted compression-belts disposed at an angle to each other, link belts carrying said compression-belts, a plurality of sprocketwheels arranged at the ends andat'intervals in the length of the link belts, transverselydisposed backing-bars extending completely across said belts at 'points between their upper and lower runs, auxiliary bars carried by the transverse bars and dis osed in a direc- `tion` of the length of thebe t to form a rigid' backin for the slats of which said compressin-be ts are composed, adjusting-screws connecting the transverse bars, and continuous filter-belts surrounding the compressionbelts, substantially as specified.

2. ln a continuous press, a pair of slatted belts forming compression members, the slats of one belt being provided with overlapcping e of Ablocks to form continuous rims at the si the belt.

Inl testimonythat l claim the foregoing as my own l have hereto afiixed my signature in the presence of two witnesses.
