VILLIAM KRUTZSCH, OF DAYTON, OHIO, ASSIGNOR TO THE BUCKIEYE IRON AND BRASS VORKS, OF SAME PLACE. OIL-PRESS IVIAT. JECIFICATION forming part of Letters Patent No. 328,414, dated October 13, 1885. Application filed July 1, 1985. Serial No. 170,377. T all whom, it may concern: Be it known that 1', VILLru KRUTZsoH, a resident of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Oil-Presses, of which the following is a specification. My invention relates to an improvement iu the face of platens for seed-oil presses. It has been customary hitherto to make the 1o face of the platen or box with transverse corrugations or curvilinear lines, so as to prevent the cloth from slipping under the face of the platen. In practice the form of platen-face has sei 5 rious objections. As the meal is of a yielding nature it spreads laterally under pressure. It is in some degree held in place by the cloth; but as this is thin and cannot be used strong enough to overcome the creeping tendency zo of the meal the cloth is soon stretched, and after alittle more use is torn and rendered wholly worthless, making the cost of the cloths a heavy expense in the mz'tnufacture of seedoil. My improvement overcomes these diffiz 5 culties by making the face of the platen a series of curvilinear or oval projections, each surrounded on all sides by a concave channel or furrow, so as to allow the oil to escape around the convex or curvilinear projections 3o and pass off through the furrows or channels. Another object of my invention is to procure an easier escape of the oil over the face of the platens. All of which will be more fully set forth in the description of the accompanying drawings, making a part of this specification, in Which- Figure l is a plan view of the oil-box having the platen-face removed. Fig. 2 is a longitudinal cross-section of t-he finishing-boxes 4o in position as used. Fig. 3 is a cross-section on line w af, Fig. 2. Fig. 4 is a broken plan View of the face of the platen, the transverse lines showing the transverse corrugations or projections. Figs. 5 and 6 illustrate the wearing of the cloth in the old form of platens. My improved platen and box is used with the ordinary press and need not be described. A represents a common oil-box. It is provided with a series of longitudinal channels, 5o c. B represents the platen or face of the box, (No model.) which is secured upon the box vertically over the channels c, as shown in Figs. 2 and 3, in the usual manner. b represents a series of iue holes pierced through the face of the platen leading into the channels c. E represents a channel formed around the box outside of the platen, forming a gutter into which the oil escapes, and leading to a spout or outlet, D, at one end of the box. F F represent steam-pipes for heating the boxes. G represents the cake of meal pressed between the platens. 'f H represents the cloth or bag which is folded around the meal or cake. I represents convex projections or curvilinear points formed by the crossing of a series of longitudinal and transverse grooves, furrows, or depressions. d d represent the transverse furrows. e e represent the longitudinal furrows. 'Ihe holes b are pierced through the intersection of these furrows in the face of the bottom platens, so as to carry the oil into the chan- 7 5 nels c. I have shown these furrows running at right angles to each other in planes parallel with the sides of the box; but the direction in which the checkered furrows run is immaterial. It is necessary to have the projections of curvilinear or convex form, so as to avoid all sharp or abrupt points and lines, which would tear the cloth. In the operation of pressing oil the parts are usually employed as follows: After being formed into a cake by a light pressure the meal inclosed in the cloth H is placed between the boxes of the press. One cake is placed between each two boxes, as shown in Fig. 2. 9o The cake G is then placed between the two box or platen faces, and a series of them is usually placed one above the other under hydraulic press and subjected to severe pressure. \Vith the ordinary platen or box face the cloth would soon stretch laterally and then commence to tear at the ends, as shown iu Fig. 5, and with further use would usually tear in the form shown in Fig. 6. I have found by experience that with the longitudi- 10o nal and transverse or checkered form of furrows and o'val projections the cloth will last very much longer and the oil escape more freely than with the common form ofplaten. The corrugations on the lower side of the box are the same as those on the upper side; but there are no holes for the oil to escape through The oil all escapes through the rows or grooves, and-the intersections of the furrows provided with small holes b, leading to the furrows c of the box A, to which the platen is attached, substantially as described. 3. In an oil-press, the combination, with the box A, an upper platen formed of aseries of convex projections intersecting each other at right angles and surrounded on each side by concave furrows or grooves pierced With holes b, leading into the channels c, and the bottom face formed of corresponding projections and grooves or furrows, substantially as described. In testimony whereof I have hereunto set v niy hand. WILLIAM KRUTZSGH. Witnesses: JOHN L. H. FRANK, FRED Ecm.
