CHARLES STRUEBIG, OF MILWAUKEE, WISCONSIN.

MAT FOR SEED-PRESSES.

SPECIFICATION' forming part of Letters Patent No. 321,258, dated June 30, 1885.

Application filed May 4, 1885.

To all whom it may concern.-

Be it known that I, CHARLES H. STRUEBIG, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Mats for Seed-Presses, and I d'o hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to mats for oil-presses, and will be fully described hereinafter.

In the drawings, Figure 1 is a vplan view of the frame upon which my improved mats are made, showing a partly-completed mat thereon. Fig. 2 is a plan view of the completed mat. Fig. 3 is a plan view of a needle, and Fig. 4 is a plan view of the compressing mechanism with a partly-finished mat therein.

A A A2 A5, Snc., are needles, which in the rst stage of the construction of a mat are clamped between plates B B at their center, the latter plate carrying lugs b, each pair of which separates each needle from its neighbor, the plates Bl B being held together by screw -clamps C. After these needles have been placed in the clamps the operators may work on the frame at once, each beginning at the plates B B and working outward, as follows: The rope used is of hair, and the end of each rope is spliced about an outer needle, and then, starting at A, the rope a is passed under needles A A2, over needles A3 and A4, under needles A5 A5, over A7 and A5, under A A10, over A11 A12, under ,A13 A14, and over A15, back under A11, over A13 and A12, under" A11 and A1", and so on until the border is reached, and then the rope a, starting at A15, is passed over A15, under A14, over A15, under A11, and so on, passing under A and back over and under alternate needles until it reaches A15 again, where it is spliced. In this last row the rope is twisted upon itself with a needle between each twist.

The lower half of Fig. l gives the appearance of the mat at this last-described stage with the lines of rope parted from each other, while the upper portion gives the appearance of the same after the lines have been pressed together by hand, or,in other words, worked close.77

The next stage in the manufacture consists in removing plate B and lifting the half-fin- (No model.)

ished mat from it and then placing it on frame D. i The frame D is rectangular, and has lugs d at or near each corner to receive screwshafts E, and a bar, F, extends across one end of the frame, and is provided with pins or lugs f, similar to those on plate B, while another bar, F, having screw-threaded openings through its ends, is arranged parallel with bar F, and a shaft, E, is passed through each of these openings. Except that bar F travels on screw-shaft E, it is just like bar F, having a row of lugs or pins arranged along its entire length, and when the mat is laid on the frame the ends of the needles lie with each pair separated by a lug or pin. Now, by means of a crank on each shaft E, the two shafts are turned and the bar F screwed up toward the bar'F, and the two sections of the mat are compressed into one compact mass. Then, by means of the needles A A A2, Ste., each of which has an eye at each end to receive the tapered end of a rope, G, the body of which is of about the diameter of the needles, the rope G, beginning in the middle, 1s carried through the fabric to take the place of the needles, and after being drawn tightly is interlaced at the terminal corners of the mat, and the result is a complete mat, H. It will be noted that the surface of the mat is raised, as ath, on each edge of the mat. This is to give additional strength to the structure, and is produced by increasing the diameter of the rope of each section, as shown in the lower half of Fig. 1.

When the mat is in the press, the raised portions h lie outside of the edges of the compressing-plate. l

Mats made according to my invention present a practically even and level surface to the press, and are very strong and durable. The ropes or cords in the sections of the mat are twisted in opposite directions to keep the mat from warping in process of construction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A mat for presses, Sto., consisting of aseries of longitudinal cords interlaced about a series of transverse cords, then compressed and bound together by the transverse cords, as set forth.

2. In a mat, the combination of the trans- I verse cords with the longitudinal cords, the latter interlaced with the former, and having increased diameters toward their outer ends.

3. A mat formed with side ridges and intermediate level surface, as described.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
