MAT FOR PRESSES.

3IPEGIFICATION forming part/of Letters Patent No. 695,266, dated March 11, 1902. Application filed October 1 2, 1901. Serial No. 78,420. (No model.)

To all whom it may concern.-

Be it known that I, CARL Gusrnv BAUM- GARTEN, a citizen of the United States, residing at Sweet Home, in the county of Lavaca, State of Texas, have invented certain new and useful Improvements in Mats for Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to presses in general, and more particularly to the mats thereof; and it has for its object to provide a mat particularly designed for use in expressing oil from cotton-seed or other oil containing vegetable matter, a further object of the invention being to provide a construction which may be easily cleaned and will be efficient in operation.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view showing the mat. Fig. 2 is a perspective view showing the back plate of the mat. Fig. 3 is an elevation showing the perforated metal plate that is disposed upon the back plate. Fig. 4: is a View showing the press-cloth. Fig. 5 is a view showing the exterior woven-wire sheet. Fig. 6 is a horizontal section taken longitudinally through an intermediate mat. Fig. 7 is a section on line 7 7 of Fig. 6.

Referring now to Fig. 1 of the drawings, there is shown a single-faced mat comprising a back plate 5, whichis provided with the upper and lower side flanges 6 and 7 and the end flanges Sand 9 on one face, the mat in practice being'stood on one edge with the flange 6 uppermost and flange 7 lowermost. Vertically of the active face of the plate 5 are formed the ribs 10, which extend from the upper rib 6 to points near to the lower rib 7, from which latter they are separated by slight interspaces, as shown. The upper or inner face of the flange 7 is concaved, so that oil falling thereon will run to the center thereof, and at the middle of the under side of the plate 5 is formed a channel 12, one end of which communicates with the inclosure of the marginal ribs of the plate, While the other end opens through the bottom edge of the plate, so as to direct oil to a longitudinal opening 20 in the bottom of the press-box in which the mat is used. Against the ribs of the plate 5 is disposed the perforated metallic plate 13, which is a backing-plate and against which is disposed the press-cloth 14:, upon which in turn is disposed the metallic screen or cloth 15, the several parts being held to the plate 5 by means of bolts 16, engaged with the plate and with the longitudinal'strips 17 and 18, secured against the wire-cloth at the upper and lower edgesof the mat.

To prevent passage of the material under treatment frombetween the mat and the next cooperating mat through the opening 20 in the bottom of the press-box, the plate5 has a foot 19, which extends at right angles thereto and is secured against its under side in position to lie in the slot 20 and project beneath the cooperating mat.

It will be understood that an intermediate mat has both of its side faces provided with the ribs, against which are disposed the back ing-plates which support the press-cloths and screens, the mat herein shown being an end mat.

In practice modifications of the specific construction shown may be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A mat for presses comprising a back plate having a longitudinal flange at its lower edge having its upper face concaved, and means upon the face of the plate above the flange and coactingwith the flange to receive the foraminous portion of the mat and hold it in spaced relation to the face of theplate.

2. A mat for presses comprising a back plate having vertical ribs and inclosing upper, lower and end flanges, said ribs extending from the upper flange to near the lower flange, the lower flange having a concaved upper face, and the plate having a passage therethrough arranged to conduct liquids from the upper face of the lower flange through the lower edge of the plate, aperforated plate disposed against the flanges and ribs, apresscloth disposed against the perforated plate,

and a screen against the press-cloth, the back 1 plate, said plate having a passage arranged plate havingafoot projecting from the lower to convey liquids from the concaved face of edge thereof beyond the screen. the flange through the lower edge of the plate. 3. Amatforpresses coinprisingaback plate In testimony whereof I affix my signature 5 haging a longitudinal flange at its lower edge in presence of two witnesses.

an having its upper face concaved, spaced ribs upon the face of the plate above the CARL GUSTAV BAUMGARTEN' flange, and means coacting with said flange Witnesses: and ribs to hold the foraminous member of F. G. PATTON, I0 the mat in spaced relation to the face of the A. A. LEDBETTER, Jr.
