To all whom it may concern: 7

. v Be it known that I, J OHN-C. Fmnn'cun'r, a citizen of the United States, residing at Akron; in the count of Summit and State of Ohio, have invent certain new Improvements in Fluid-Extracting Presses, of which the following is a specification. V

This invention relates to animprovement in a fluid extracting press, all substantially as herein set forth and more particularly pointed out in the claims.

- In'the various forms of presses patented by me heretofore, I have experienced diflicult in effecting a proper escape of the flui and in holding back the solids. Thus,

one diiliculty consisted in preventing buckling or displacement of certainpartsandin maintaining uniform spaces forthe esca of the oil. The solids would alsopack 1n places. The object of the presentimprovement is to provide an effective arrangement of parts to overcome such difficulties, and to provide a movement which will facilitate the escape of the fluid and prevent the escape openings-from clogging, and a further ob ect is to simplify the structure and re duce its costand upkeep to a minimum. I

In the accompanying drawin Figure 1v is a sectional view longitudina y through the shell of the press. Fig. 2 is a cross section of the press on line 22, Fig. 1. V Fig. 3

I is an enlarged view and sectional detail of one of the fluid distributing ducts or channels in the spiral wall of the rotating body.

4 is a perspective view of oneof the divislon walls used between the baflle members.

. In one form of the invention the prem comprises a casing or shell --'2.cast in-one pieceor otherwise formed to provide an in-- tegral cylindrical inclosure for one or more -.rotary pressing members. Thus, I may use a two

rotor members

3 and 4 geared to rotate in opposite directions at the same speed,-o1, I may omit the gearing and modifytheconstruction in other ways W1i3h011t1 affecting ,thefpresent improvement.- As shown, however, a main feed and presser member 3 is provided with a hollow shaft or integral. "shaft extensions 5 which are adapted to rotate in hearings in suitable standards 6 and 7, and a second baflle member 4 is mounted on a shaft 8 having bearing in standard 6 and-in the wall 9 of shell'---2-i The body of rotor member 3 is round and tapered, and

: Specification ofLetters intent.

Patented Mar. 9,1920.

the bore or chamber 1 in shell 2 for rotor member 3' has a slight taper with a flarir1ttg= exit'll at one end. This exit may be open or arranged to'be opened or closed, more or less, by a flanged cone-shaped rin 12 secured to the end of shell 2 by. bolts an notched baflle portion 4 oppositethe division wall 15 of member 3.

Therotor member 3 is in effect a screw length witha spiral thread or flight and a spiral circumferential channel 14 for the material, and the baflles 4 are mounted to rotate inthe annular circumferential channel between the annular division walls 15 at the feed end of the press and are slotted to re-' ceive the cross connecting portions of the division walls so asgto press thematerial and extract the fluid therefrom during-its forced travel forward in the channel. table division plates-4f are also placed between the notched baflle walls 4 directly op--. posite each annular wall 15' to prevent the drainage openings in such divlsion walls from being uncovered and the solids from passing into said openings.

The present Inventiomis distinguished, more particularly, in the means provided for permitt the fluid to escape from the spiral channe 14," regardless of whether one pressing member or two or more are emloyed Thus, the annular and spiral di- Non-rotanuts. The material is fed into the shell I through a hopper 13 or in any suitable way,

and division plates 4 are placed between the member in that it is provided overits main vision wall or flight- 15 forming the channel 14 is made relatively wide and of a. diameter to bring its peripheral surface in close pi'ox imity to the curved surfaceof bore 10, and

the-space allowed may be varied slightly by v adjustment of the rotor member longtudinally in the tapered bore 10 so that o the fluid and not the materialmay escape. The circumferential edge or periphery of division wall 15 is also preferably provided with a peripheral gmo've 16 to receive the fluid which escapes from channel 14, and the fluid thus gathered up is discharged through a series of tubes 17 extending from said ve and radially in rotor member 3 to a central -,longitudinal ope This opening 18 has outlet t ugh one or both of the hollow shafts or shaft extensions 5, and the tubes 17 are preferably-of tapering or flaring form internally with the 18 therein.

larger. inner ends open to the main discharge opening 18, thereby providing for av 5 we into them.

he construction of the press is greatly simplified by using a solid shell and forming fluid outlets in the circumferential helical division wall or flights 15 of the rotor member as described, and the escape of the fluid is materially improved and proceeds continuously with an eflectiveexclusion of the materialfrom the fluid passages. The solid or integral shell can be constructed at less expensethan a slotted or perforated or sectional shell made of special rings, and 1t may consist of a cast body with a hardened and relatively thin metal bushing adapted to be replaced when worn out. The size of the escape openings, when accurately determined, are not altered or changed by wear or use of the machine, and the escape of the oil is uniform and constant at all points the full length of the shell. With the present a construction it isan easy matter to determine the proper size of opening and maintain the opening to size without any trouble or great expense. r v

The movement of the material is longitudinally of the shell, and in the rotation of the pressing member 3 the oil follows the roove or channel in the periphery of the ight and each radial opening Wlll carry the oil away while coming constantly opposite all parts ofthe cake, that is, the material compressed in the channeL, The holes or openings through the flights are also made large enough so that all particles escaping from the channels can not clog such openings, and the taper also prevents such clogging. J

The machine shown is supported on a base with the rotor member 3 operating in a horizontal plane, that is, on a horizontal axis. However, I wish it to be understood that I may support the shell and screw member in a vertical position and any suitable means may be used to adjust the shell or screw member relatively to each other so that the space between the shell and the flights of the screw may be of uniform size and no unequal wear produced.

In one form of press patented byme I use a conical worm or screw within a divided casing of conical form, and emplo a different form' of bafile member at the fee end ofthe press, and in a press of that or kindred type it is not desirable to continue the perip eral channel and make drainage openings in the flights at the'feed end of the press. Therefore, I do not limit myself to the use of the drainage openings throughout the full length of the flights vas they may be used in only a portion of their a length and where most effective.
