To all whom it may concern:
Be it known that I, JOHN C. F IDDYMENT, a citizen of the-United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Presses, of which the following is a specification.
This invention relates particularly to that type of presses designed for expressing liquids from seed and similarmaterials, and more especially intended for the extraction of cotton seed oil from cotton seeds.
A special object of the invention is to utilize, in connection with the cylinder and expressing screw therein, certain novel improvements which insure a uniform action on the material as it passes through the press, and at the same time obviating tendencies of the mass of material to rotate within the cylinder or press chamber as it is advanced toward the discharge end of the same, and consequently checking any retrograde or creeping movement of the material backward toward the feeding end of the machine.
Most all kinds of material, when pressure is first applied, has a tendency to flow or crowd back toward the feed end of the machine with the result of interfering with the free admission of the stock to the feed chamber of the machine, for the reason that the crowded-back material occupies the space that should be occupied by the untreated material. In presses,'of the expressing type, the efi'ect of this retrograde or creeping back movement of the material is to prevent the machine from taking the charge that is necessary to give it the proper compression, as it is well known that the amount of material introduced at the feed end of a press governs the pressure therein,
and should there be less material than would After the material has'passed from the feeding end of the press cylinder for a distance of say two feet, by Way of example, it
is in a more compact condition, and has notthat tendency to How orcreep toward the feed end, and it is therefore an object of the present invention to utilize a suitable check or bailie designed to seal or close one nf lie! s rew flights so that it shall. be impossible for the material, after having once passed the point referred to, to move back toward the feed end, and at the same time preventing thepressure that is on the material nearer the outlet end of the. press chamber, (which pressure is the heaviest) from being in any Way communicated to the material between the feeding-in point and the point where the check battle or stop is located. This improvement is intended to insure the press getting the material in the proper amount, and to regulate the flow of the material through the press chamber from inlet to outlet in such a manner as to provide for and maintain a uniform expressing action throughout the machine. Y
In carrying out the invention, the same is necessarily susceptible to a wide range of structural modification without departing from the principle or sacrificing any of the advantages of the invention, but certain simple and practical embodiments of the invention are illustrated in the accompanying drawings, in which Figure 1 is a horizontal longitudinal sectional view of a screw press, shown equipped with suitably arranged check-battles to pre vent retrograde creeping or rotation of the material, for the purposes already-explained Fig. 2 is an elevation of a fragment of the expressing screw, showing one means of in- I is a vertical'cross sectional view of the press illustrating a modification of the means that may be employed for controlling oppositely arranged movable bafiles. Fig. 5 is a similar View showing another form of movable battle and means for controlling the same in pairs.
Like references designate corresponding parts in the'several figures of the drawings.
As indicated, the improvements are particularly designed to be associated with the feed screw type of press for expressing liquids. Hence, for illustrative purposes, there is shown in the drawings a screw press embodying in its organization a perforate press cylinder 1 essentially .consisting of a plurality of rings 2 arranged in side by side relation, and so spaced as to provide a continuous series of annular outlet" openings or slits 3 through which the expressed liquid or oil escapes to a suitable receiver therefor. Also, the press shown includes an expressing screw 4 driven by suitable means, and having a tapered drum or body portion 5 and spiral carrying flights 6, which serve to pass the material through the press chamber'and also place the same under com ression by reason of the tapering form 0 the drum or body portion 5, the larger end of which is disposed at the discharge end of the press chamber or cylinder.-
According to the present invention, it is proposed to locate suitable check baffles at proper distances or points oflocation away from the feeding-in end of the press, so as to hold the material up to its compression and compacted form and to prevent retrograde creeping toward the feed end. According to the embodiment suggested in F g. 1, separate parts of diametrically opposite check baflies 7 and 8 may be employed. The said baflles 7 and 8 are shown in the form of slides working in guide openings 9 provided in the cylinder walls, and the check bafiies 7 are shown as locatednearer the feed end of the machine than the baflies 8. The baflles 77 are arranged diametrically opposite each other at opposite sides of the press, and likewise the bafiles 8, which latter are located nearer the center of the ma-.
chine, but the bafiies 7 and 8 at the same side of the machine may be conveniently operated in unison by means of a rocking connecting lever 10, pivotally connected at its extremities as at 11 and 12 respectively to the outer ends of the battles 7 and 8, ,and pivotally mounted intermediate its ends as at 13 upon a supporting bracket or the like 14. The pivotal support 13 for each lever 10 may be movable and spring held, as indicated at 15, to allow yielding of the parts under abnormal pressure or strain.
The baflles 77 and 8-- 8 are alternately moved into and out of annular pressure re-- taining channels 16 which are confined between straight holding flights 17 which form the side walls of said channel 16 and interrupt the spiral passages between the flights 6, while at the same time permitting communication with such spiral passages by means of short, oblique connecting passages 18, as may be plainly seen from Figs. 1 and 2 of the drawings.
Suitable spacers 19 may be employed to.
hold the bafiles 7 and 8 to a sufiiciently close fit within their channels 16, and short operating cam sections 20 are likewise fitted at one side of the channels 16 so as to operate against the inner ends of the bafiles 7 and 8 to move them outward and out of the way of the advancing material. For instance, when a cam 20 moves one of the baflies 7 outward,
as shown in Fig. 1, the baiile 8 connected v with said baffle 7 is moved inward to an operative checking position by the leveri-10, and vice versa, thus securing alternatejand automatic action of the opposite pairs'of connected baffles. Also, according tothe present invention, at a point nearer to the outlet end of the press chamber, where the material is under greater compression and has been more compacted, lnwardly pro ecting stationary check baffies 21 may be fitted to the inner wall of the press chamber or cylinder so as to project into the straight annular pressure retaining channel 22 crossing and interrupting the spiral passages between the screw flights 6. Again, where it is desirable or preferable to utilize but a single pair of diametrically opposite baflles in the form of slides 23-23, a rocking operating yoke 24 maybe employed in connection therewith as shown in Fig. 4. This yoke is shown as hearing against the outer end of the bailie slides-23 while the inner ends of said slides are engaged by an operating cam section 25 on the screw body. The yoke 24 is placed astride the press, and the intermediate part thereof slidably engages a swinging supporting bolt 26 hung 'on' a pivotal support 27 and carrying a holding spring 28, the tension of which'is adjustedby a nut 29, said spring permitting the parts to yield under abnormal or excessive strain. Also, instead of movable stops which are in the form of slides, there may be employed movable stops inthe form of pivoted plates or blocks 30 as shown in Fig. 5. These plates or blocks 30 are moved outward by an operating cam section 31 on the screw drum or body, while their inward movement is controlled by a connecting yoke 32 placed astride the press cylinder, pivotally supported at an intermediate point 33, and the opposite extremities of which are connected by the links 34 respectively with the opposite blocks 30,
From the foregoing description it will be understood that various other forms of bafiles may be utilized, as well as baflies arranged in different positions and'operated by different means without departing from the spirit of the invention. Also, it will be understood that the straight annular pressure retaining channels may be formed in other ways than those shown in the draw-- be selected without departing from the principle of the invention.
