' SPECIFICATION forming part of Letters Patent N 0. 731,737, dated June 23, 1903.

Application filed May 22, 1902- Serial No. 108,586. (No model.)

. Toall whom it may concern.-

Be it known that I, VALERIUS I). ANDER7 SON, acitizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Presses, of which the following is a specification.

My present invention pertains to improvements in presses designed more particularly for the treatment of seeds and the like for expressing the oil therefrom.

In the accompanying drawings, Figure l is a top plan View of the press; Fig. 2, a longitudinal sectional View thereof; Fig. 3, a detail; Fig. 4, a longitudinal sectional view of a modified form of construction, and Fig. 5 a top plan view ofthe same.

The object of the present invention is to provide a press which will effectually treat or handle seeds and like substances-such, for instance, as cocoanutand thoroughly disintegrate and press the same, so that all or practically all of the oil is expelled or forced out therefrom.

While the press is designed more particularly for the treatment of the substances just referred to, still I donot wish to confine my invention to these particular substances, as ita lhe press seems to include a wide operative ed. a.

Referring first toFigs. 1" to 3, A denotes a shell or casing, perforated throughout its length or a portion thereof, as may be found necessary in the treatment-of any particular seed or substance. Mounted within said shell or casing is a shaft B, which has its hearings in the head-frames O and D and in a footframe E. Shell A occupies a position between and is supported by the frame D and an intermediate frame or casting F.

In practice shell or casing A will be made up in a manner similar to that set forth in mypending application, Serial N 0. 95,404, filed on or about February 24, 1902, and reference is hereby made to said application for the details of construction of this portion of the press, no claim beingherein made to said structural features. The forward or head end of the shell or casing is provided with a feed-hopper G, and the material which is fed into said hopper is discharged at the opposite end against a head H, mounted on the shaft.

Said head in the form shown is conical in shape, though this shape is not essential to the complete operation of the machine. The shaft at this point is polygonal in cross-section, so that although the head rotates therewith, yet it may be moved toward or from the shell, as occasion may require, suitable'm'eans being provided to effect the desired adjustment. The polygonal portion of the shaft also carries a sleeve or collarI, having a worm J formed thereon, said member occupying a position within the discharge end of the shell or casing and rotating with the shaft. The remaining portion of the shaft is cylindrical in form and has mounted upon ita quill or sleeve K, which has a series of separated screws L,

M, and Nformed thereon, the number of the screws, however, being optional, so long as two or more are employed. A gear 0 is secured to an extension of the sleeve which projects out between the head-frames O and D, and a similar gear P is keyed or otherwise so cured to the shaft.

Q denotes a clutch-pulley or other source of power, motion being imparted therefrom through a shaft Q to a gear R, and thence to gear P through gears S, T, U, and V.

Shaft W, which carries the gears S and T,

also carries a pulley a, and a straight belt 1) extends therefrom to a similar pulley o,mounted upon a shaft d at the opposite side ofthe frame. Shaft d has secured to it a gear 6, which in turn imparts motion to gear 0 through intermediate gears f and g. A

' weighted tightener-pulley It bears on the belt.

When the press is running'empty, the gears O and P will with the arrangement of gearing-shown rotate in unison, so that the same rate'of rotation will be imparted to the quill and tothe shaft. When, however, a certain degree of pressure is exerted or reached in the feed end of the shell or in that portion within which the quill works, the belt will slip in a greater or less degree, depending upon the pressure exerted uponthe belt by the tightener. Thus while the end screw J rotates continuously and positively the quill and its screw rotate intermittently or rotate at varying rates of speed.

The action of the press is as follows, assuming that whole cotton-seed or Whole linseed is. being run through it: The whole'seed is fed into the hopper and is caught by the first screw L. The material is carried around and forced forward by the screwinto the space between it and the next screw M. The seed is partially disintegrated and is compacted into the space between the screw'L and the adjacent screw until a certain degree of conipression is effected, when screw M takes hold and acts on the mass. The farther along the mass goes in its travel through the press the greater the degree of compression, which compression is maintained at all times. The seed is effectually broken up, the oil-cells ruptured, and the oil forced out. Screw M acts in the same manner as screw L, forcing. the material on toward screw N, which in turn forces it toward screw J, which then takes it up, effects thefinal compression, and forces it out against the head H. Said head. forms an abutment against which the screw will force the material, and it also serves to break up or disintegrate the material or mat as it leaves the press. The mass may be said to be subjected to a torsional strain or pressure as it passes through the press.

In the treatment of seeds having fibrous hulls and similar substances the screws carried by the quill will so efiectually compress the mass and form such a hard cake or body that the discharge and final compression screw cannot take hold of it unless means be provided whereby the further compression is stopped until the discharge-screw can relieve the press to a certain extent. In other words, the compression in the major portion of the press is momentarily arrested; but that degree of pressure attained is still lfeld to prevent reabsorption of the oil by the fibrous portion of the shell of theseed and the meat or kernel thereof until such time as the discharge-screw shall have sufficiently cleared or relieved the press to enable the whole press to operate again.

The action above described is that which is thought to actually take place,-a nd whether it be absolutely correct or not'the fact remains that the oil is completely expressed (commercially speaking) from the whole.

-- seed, and the remaining mass contains simply the hulls and dry meat or kernels. This material maybebroken up, separated into its constituent elements, and used in a manner similar to the" prod ucts resulting from the old method of treating seeds.

It is to be understood, of course, that the press may be used on substances other than seeds. 3

The mat which is formed will, as'noted, be held under constant pressure, which pressure increases toward the discharge .end of the press.- As beforestated, this pressure-pre- Vents the absorption 'of the oilby the. mat or fibrous portions of the seeds, permitting it to I pass therethrough in a clear condition. In

other words, the fibrous portions of the seeds act as a strainer or filtering medium for the oil, all fine or floating particles being held back thereby.

No claim is made herein to the method of treating seeds and like substances for the ex-- pression of oil therefrom, which method is incident to the use of the present press.

It is immaterial whether the screws be right or lefthand in their arrangement throughout. This applies to the series of screws mounted on the quill, as well as to the screw carried by the shaft. Screw J must, however, rotate in such a direction that its inner end will cut into the material forced into the space between it and the adjacent screw.

In Figs. 4. and 5 a modified forniof the press is shown. In this construction a two-part shaft is employed, one member or section a. thereof passing through the head of the press into the shell or cylinder and upon which is mounted a series of screws, two, b and 0, being shown.

These screws, as in the former.

case, are separated from each other. The

second shaft member or section (1 eirtends into the opposite or discharge end of the shell or cylinder, the abutting ends of the sections being preferably socketed one in the other for the purpose of mutually supporting and bracing each other. The shaft-sections are,

.however, free to rotate independently one of the other. The section (1 carries a screw e and a frusto-conical member f, the smaller end of which extends into. the open discharge end of the shell or cylinder. Ashaft g, driven by a pulley or belt-wheel h, imparts through suitable gearing, as shown, a continuous rotary'inotion to the shaft-section d and the screw e. A friction-clutch '5 works in conjunction with pulley h and imparts motion to a shaft j, which through suitable gearing in turn imparts motion to shaft-section a and the screws carried thereby. The arrangement'of the clutch is such that only a certain degree of compression can be reached within the press, and when this point is attained the shaft j, and consequently the shaft-section a, cease to rotate. as thus constructed is the same as that above described, though this form is found to be preferable for useupon certain classes of materials.
