OIL-PRESS MAT.

SPECIFICATION forming part'of Letters Patent No. 227,670, dated May 18, ,1880.

Application filed March 20, 1880.

To all whom et may concern Be it known that we, WILLIAM S. ARCHER and HENRY L. POPE, of Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in Oil-Press Mats 5 and we do hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to an improvement in presses for extracting oils from seeds 5 and the novelty of our improvement consists in the construction and combination of the devices employed, whereby the greatest amount of oil can be obtained from any given amount of meal or seed, and whereby the oil, having been once expressed from the meal, cannot be reabsorbed by capillary attraction when the pressure is removed from the press, all as will be herewith set forth and specifically claimed.

In the accompanying` drawings, Figure 1 is a plan View of one of our improved divisionplates. Fig. 2 is a reverse view of the same. Fig. 3 is a plan view of the perforated bedplate. Fig. 4 is a reverse view of the same. Fig. 5 is a sectional view, in end elevation, through two pairs of these plates as they would appear in the press.

The division-plate A, Figs. l and 2, has an oblong shallow pan upon its upper surface,

formed by the anges a, surrounding its edges. This pan forms the first receptacle for the oil as it is pressed from the meal. Running longitudinally along the bottom are a set of parallel ribs, b, which do not extend quite to the sides or ends, as represented, and the front or bowed end of the pan has its bottom slantin g to form a pocket, which directsthe expressed oil to the outlet-aperture c. The tops of the ribs b and anges a are on a level. The sides of the plate are provided with guide ears or extensions cl, which, partially embracing the standards of the press, hold the plate in its proper relations.

Upon the under side of the plate, as seen in Fig. 2, is the pressure-cap e, made slightly concave, and having transverse corrugations f, as represented.- This cap-piece rests upon the meal-sack of the subjacent division-plate.

To keep the meal warm, and thereby enabling all the oil to be expressed more readily,

(No model.\

we employ steam-pipes g, which, passing by proper connectionsI from a boiler, extend through the plate A longitudinally, as represented by the dotted lines.

The bed-plate B, upon which the sack of meal rests, Figs. 3 and 4, is an oblong thin metal plate, slightly concave upon its upper surface, and having transverse corrugations i. This plate is flat upon its under surface, and has a flange, j, upon each side and'at the corners, which ts over the outer ribs, b, and serves to hold' the plate from displacement when resting on the ribs. lneach of the transverse corrugations or gutters t is a row of perforations, k, which extend through the plate, andare gradually enlarged, so as to form countersunkapertures, as seen in Fig. 5.

The meal, after being inclosed in its sack, is placed upon the plates B inthe press, and is pressed thereon by the caps e of the plates A, and the oil being expressed passes down through the apertures c between the ribs b and into the pocket, whence itis conducted, through pipes leading from the apertures e into the proper receptacle.

In order to more effectually prevent any reabsorption of the oil into the cake after it has been once pressed out, we employ a matting, s, Fig. 5, of any suitable textile material, which is placed upon the bed-plate, and may be confined by raised ribs or flanges at the edges o f said plate to hold it from spreading. This matting receives and holds the last particles or drops of oil which are pressed out of the cake, and delivers this retained oil when the next succeeding sack of meal is introduced.

This matting always remains upon the bed-- plate, and is suiciently open in its texture to permit the oil to pass freely through it.

'The advantages of the above construction are, that by means of the beveled sides of the mealconfining plates, which makes them slightly concave, the meal is more readily contained between them without danger of being pressed out at the sides; secondly, by means of the countersunk apertures the oil, when once pressed out of the meal, cannot find its way back by capillary attraction into the cake when the pressure is removed; thirdly, by means of the steam introduced into the divis- IOO ion-plates the meal is kept Warm, in which meal directly rests, having their upper surfaces corrugated or ribbed transversely, and provided with apertures smaller at the top than at the bottom, substantially as and for the purpose specilied.

4. The herein-described division-plates A, constructed with the ribs b, iianges a, and corrugated pressurecap e, substantially as set forth.

5. In an oil-press, the combination7 with the bed-plate and the meal-sack, ot' an interposed matting adapted to receive and retain the last particles ot' oil which are pressed from the" meal, as specified.

In testimony whereof we have hereunto set our hands.
