To all whom t covwera.'V 1 f Be it known that I, JOHN C. FIDDYMENT,

a citizen of the United lStates,-ia11"d residentr of Mountl Gilead, in thecounty of yMorrow 6 and `State of Ohio, have nventedfcertain new and useful "Improvements Presses, of Which the following is 'a'spec1'ieat1on-- This invention relates to a continuous' press for use in -pressing oil seeds, nuts, soy 1 beans, copra, 'and in general any substance fromfwhieh fat, oils 0r other fluid may bey and'arounda sp-rocket'wheel: 19 on 'a shaft expressed. y. .Y

An object of the invention is to 'provide such a press which Willhaveav constant.y rotation in one direction, and Willi'handle various materials eheiently' and rapidly. 1 f r Another object is vtov-'provide means for draining out the liquid rapidlyasthe material is pressed and' finally disposinglofy the material remaining' after lthey extractionI of the fluid in such 'a manner thatthe press may operate continuously and at the' same time exert sufficient pressureto express the fluid thoroughly;

this means the posltion ofa loose collar50 is adjusted, and this collar has a beveled end 51 to cooperate Awith the beveled exit end 52 of the casing 36. f' Thek solids are ejectld Vt e through the annular .passagey between collar 50 and the end of the casin The size ofthis opening vmay be varie l.in accordance with the material being treated or the degree of pressure to whichit is desired toH subject the material. -The enlarge#- ment4 46 is provided with top, bottom or side openings through which the y ejectedmaterial may pass.

At one end the casing 36'has its lower side. cut away and communicatesvwith the upper'cut away side of the casing 53 which is not quite cylindrical in shape. The cas-l ing 36 and casing-53 are shown as being made integral but of `course thisfis not essential. .Within the casing 53 is` a two part bearing member 54 in which is mount-r ed a shaft 55 asfshown in'Figure 4. Since the casing lune shaped member 56 is placed in the bottom thereof, having curved to correspond with the bearing 54.`

This isl adjustably held in position by a screw 57 as shown in Figure 4, andi-un.

nishes meansfor the exact adjustment 0f the bearing 54. Alsowhen it is desired-to remove lthe shaft 55 and parts carried'there: by, the `screw. 57 -`isremoved and the .lune

shaped member 56 may be removed endwise. This will permit thel bearing 54 and shaft 55'to. drop down to a position from which itxmay also be removed through the o en endof the casing 53. This bearing 54 a so prevents thrustv-.tendingto force sides of B and .C against walls of' channels E and F.

YAt one side there is `an Yopening through the casings 36 and 53 at their juncture with which communicates the Yfeedpassage 34.

The material is. fed from the hopper by Ythe screw 33 through the passage 34 into lthe casings 36 and 5K3- at theirv juncture, and is there received by feed mechanism which transmits it to the screw 42.

This feed mechanism 1s yo 53 is not-entirely cylindrical, a

its upperv surface` f olutions ofthe shaft' 1 6.A

acter and is illustratedin Figs. 4 to 7 and 9. The shaft 55 is provided with three ring like members A, B and C. The member A has six teeth a as shown, while the members vB and C have -threecut outs b and 0 respectively. Each of the three cut outs is yapproximately oneesixth of the circumference in extent, and the two-members B and C are located on the shaft 55 in such relation that a cut out in one member comes opposite the solid portion of the other. The three members A, B and C are separated from each other lengthwise of the shaft 55 by portions of the bearing 5 4 as shown clearly in Figure 4.

The shaft 16 has` three portions D, E and and C respectively. The member-Dirhas two cut outs d diametrically opposite and separated by riby portions d. Each cut out is U approximately one-sixth of the circumference 1n extent. 4The portions E and F are channels formed byz-ribs on the. shaft,

and each has a projection e and f respectively which is or may be about one-sixth ofthe circumference, the projections@ and f being arranged so vthat they always ex-` -A cooperate tohold the shaft 55 kagainst movement except at two points in therevolution of the shaft 16. Whenever a cut 'outv vtlf-comes oppositea tooth a, either the pro-` jection e is in positionto cooperate with a cut out b in the member Bor the projection f is in position to cooperate with ka cut out c' inthe member'C.l In either case'the shaft is given a one-sixth revolution. While the rib Z is in the position shown in Figure 5, where itv practically contacts .with two teeth a, the member A is held against movement. Itis evidentthat the shaft 55 is driven in this manner step by step lfrom the constantly rotating shaft 16 and is given one complete revolution bythree rev- In Figs. 5, 6 and 7, as the shaft 16 is revolvin counter clockwise.

The vmaterial vis fed by t e screw 33 intothe channel in the member E at the point X, and the projection e ismoving away 'from the incoming material whichfills up the channel behind the same until the projection e has made nearly a revolution, when the ymaterial passes through al cut out be# hind this projection or stop e into the next channel. In similar vmanner the material thus Vpassed vinto the second channel kis passed through another cut out inlfthe vchannel F. The channels E and F areseparated by a-channel as sliown'in Figure [4 which well vas Fig. I 3, i

comes opposite the wide bearingmember between the membelSB adf C,- v'vlldinally,the

material passes through a cutout from the channel F'to `the screw membe1.42 fr i ,l

'Figure 9 is a development of the of the shaftlG having themembers' the dot and dash lineas shown from the oint of introduction'through the cut outs rom one channel to the succeeding one and a revolution, the member B is stationary,

and the ri hery thereof engages-the bottom an si es of the channel' E closely enough to prevent any of the material which has been previously lntroduced and is now on the pressure side of this stop e from coming back to the starting point. It is therefore forced into the adjacent channel through the cut out in the walls of the first channel as described. The same laction takes place in the channel F. These stops formed by the rojecting portions of the members B and substantially fill the channels and cannot be displaced in any manner. In Figures 6 and 7, for example the point marked H acts as a stopy for preventin the material from revolving with the sha t or passing this point. The projections e andA f can pass through b and c or b and c,-but

the material cannot follow, and while f is passin through c the channel is blocked by B, sot at if any material should get through while f is passing it cannot get out into the feed. The material is therefore caused to travel along under pressure to a point where it is taken up by the screw.

It may be noted that this feed mechanis may be used Ywith other types of expressing apparatus, and is in no way limited to the specific form here shown, although it coopcrates therewith.

The bolts 59, in Figure 1, may be used asA i jack screws to take the casingoti' of .the

shaft if the machine stalls. these screw bolts is fixed and the other is screw threaded and passes through thelugs as shown` v f f Means may be provided if desired for varyin the Yrate of feed ofthe screw 33 since ie compression is affected by the amount of material fed into the first channel. It is obvious that vdetail changes ymay be made. in the precise form and arrangement of various elements without departing from the spirit of the invention and it is to be understood that theinvention is limited by the scope of the appended claims.
