OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No. 243,596, dated June 28, 1881.

Application filed March 23, 1880. (ModeL) Be it known that I, JEAN J. Mrsrao'r, of Bryan, in the county of Brazos and State of Texas, have invented certain new and useful Improvements in Oil-Press Mats; 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in oil-press mats; and it consists in uniting the two outer leaves together by means of a leather back which covers both of their outer sides.

It further consists in attaching the, central leaf to the center of the hinge which unites the two outer leaves together by means of two rods or bolts and a connecting leather link.

It still further consists in forming each one of the leaves out of one or more thicknesses of metal, which is backed up with or lined by press-cloth or cork, all of which will be more fully described hereinafter.

The object of my invention is to produce a mat which is provided with three leaves, whereby two cakes can be pressed at the same time, and the three leaves to be flexibly connected together in such a manner that the mat can be readily and easily handled, at the same time that it is made strong and durable and lasting.

Figure 1 is a longitudinal vertical section of one of the leaves of the mat and its hinge. Fig. 2 is a vertical cross-section of the same. Fig. 3 is a plan view of one of the mats open. Fig. 4 is aside elevation of the mat, one of the leavesbeing broken away.

. A B represent the two outer leaves of the mat, and O the central one. These two outer leaves are formed of two thicknesses, D, of sheet metal of any suitable kind, and in between the two sheets of metal is a thickness of cork or press-cloth, F, as shown, for the purpose of strengthening the two layers of metal, giving them a greater amount of elasticity and a greater thickness. The edges of these plates are turned over upon the inner side of the mat, as shown, and inside of these turned-over parts are placed the rods or wires G, which form the ridge or flange along the sides of the mat, as shown. Also secured to the inner side of each j .one of these leaves, at a suitable distance from its end, in any suitable manner, is the cross bar;

or piece H. Applied to the outer side of each of the metallic portions of the leaves thus formed is a layer of press-cloth or cork,I, and fastened to the outer sides of each of these leaves is a thickness of heavy leather, J, which united. These thicknesses of metal, cork, or

press-cloth and leather are all fastened together by rivets N, which are passed through all of them, as shown in Figs. 1 and 3.

Fastened to the hinge L by means of suitable rivets is a leather strip, 0, which forms a carrying-handle.

The central leaf, 0, is likewise formed of two thicknesses of metal, in between which is placed a layer of cork or presscloth, and the two thicknesses of metal and thelayer of press-cloth or cork are united together by rivets, as above described. Across the outer end of this leaf 0 is placed across-bar, P, but at the inner end of: the leaf there is no crossbar, as shown in Fig. 3. This central leafis connected to a flexible leaf or hinge, It, which is made of leather or other similar material, by means of a rod or wire, as shown in Fig. 3, and the other edge of this hinge is connected to the hinge which unites the two outer leaves together by means of a similar rod or wire, S. As seen in Fig. 4, the inner leaf, by means of its hinge, has its inner end some distance in beyond the ends of the other two leaves, but its outer end is just flush with them.

By means of a mat thus constructed the leaves will always retain a parallel position,

and the matis strong, durable, and easily handled.

I am aware that an oil-press mat composed of three leaves which are united together by short leather straps is not new, and that'it is not new to connect two leaves together by means of a leather band, and this I disclaim.

Having thus described my invention, I claim-- 1. In an oil-press mat, a leaf composed of two thicknesses of metal having placed in between them a layer of press-cloth or cork, substantially as shown.

2. An oil-press mat in which the outer leaves 4. In an oil-press mat, the combination of have applied at their outer sides a thickness of the three leaves A B G, hinges L R, and conpress-cloth or cork and a thickness of leather, necting-rods for uniting the hinge R to the 15 which leather forms the hinge for connecting hinge L, and plate O,substantially as specified.

5 the two outer leaves together, substantially as In testimony that I claim the foregoing I described. have hereunto set my hand.

3. In an oil-press mat, the combination of the three-leaves A B G, the leather covering J JEAN JACQUES MISTROT. for the two outer leaves, and which forms the IO hinge L, with the central hinge, R, connected WVituesses:

to the plate 0 at one end and to the hinge L WM. KOPPE, at the other, substantially as set forth. M. BONNEVILLE.
