ROBERT FRANZ WEEK, OF NEW ORLEANS, LOUISIANA.

OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No. 758,573, dated April 26, 1904.

Original application filed September 10, 1901, Serial No. 74,906. Divided and'this application filed June 26, 1902. Serial To all whom, it may concern:

Be it known that I, ROBERT FRANZ WERK, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Oil-Press Mats, of which the following is afull, clear, and exact description.

This invention relates to oil-press mats; and the subjectmatter of the present application is a division of a prior application for Letters Patent filed by me on September 10, 1901, Serial No. 74,906.

In the present invention it is my purpose to produce a hair mat or fabric which shall be durable in service owing to a peculiar combination of hair in different grades, and at the same time the mat is not liable to split or tear apart under the pressure of the seeds and the press-plates; nor will its threads or strands unravel, and it is capable of being folded lengthwise upon itself without breaking. These ends are secured by making warpthreads of soft pliable hair,.while the weftthreads are made of coarse stiff hair mixed with soft pliable hair.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of an oil-press mat constructed in accordance-"with my invention, and Fig. 2 is a longitudinalsection thereof on the line 2 2 of Fig. 1 I

As shown by the drawings, the fabric or mat consists of longitudinal warp threads or strands A and the weft threads or strands B, the same being interwoven together to produce a complete fabric or cloth. The warpthreads A in the present invention are made of soft pliable hair, the same being properly selected and arranged so as to be spun or twisted together in order to produce a strand of the proper length and thickness. The weftthreads B, however, are made of hard, stiff, and coarse hair mixed with soft pliable hair. The hairs are mixed in the proper proportion,

the pressure over the weft-threads.

and they are arranged in a manner to be spun (No model.)

or twisted together for the production of a strand having the'proper length and thickness. I prefer to make the weft-threads of greater thickness than the warp-threads; but this increased thickness may not be observed at all times in the manufacture of the mat when the latter is made of hair having the qualities herein described. The warp-threads are arranged in parallel relation to extend longitudinally of the mat, while the weft-threads extend across the warp-threads. The two series of threads are interwoven together for the purpose of making the warp-threads entirely conceal and protect the weft-threads. In practice I prefer to make the warp-threads greatly exceed in number the weft-threads, and I may employ from live to eight times per square inch as many warp-threads as there are weftthreads, thereby making the warp protect the weft to better advantage, because the seeds are prevented from passing through the warp and injuring the weft, and at the same time the warp serves to more uniformly distribute The increased thickness of the weft-threads imparts the desirable cushioning effect to the warpthreads, as the warp is liable to cut into the weft-threads. 7

The improved mat possesses all the good drainage qualities, because I employ horse-' hair in its manufacture, and the durability of the mat is secured by the use of long animal hair combined together in different grades throughout the warp and the weft. The mat is comparatively free from any tendency to split lengthwise under the pressure of the seeds and the press-plate, and it can also be folded longitudinally without breaking or giving way.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. An oil-press mat or cloth consisting of warp-threads and weft-threads made of long animal hair, said Warp-threads being composed of soft, pliable hair, the warp-threads at the middle of the mat being made of longer hair than the warp-threads at the selvage, and the weft-threads made of hair of medium grade, the selvage of the mat being formed by said Warp-threads of soft, short pliable hair.

2. An oil press cloth consisting of Warpthreads and weft-threads made of long animal hair, said Warp-threads being 'composed exclusively of soft, pliable hair, the Warp-threads at the middle of the cloth being made of longer hair than the Warp-threads at the selvage, and the weft-threads having hard, stiff and coarse IO hair mixed With soft, pliable hair, the selvage of the mat being formed by said Warp-threads of soft pliable hair.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
