WIRE MAT FOR EXTRACTING OIL, 800.

SPECIFICATION forming part of Letters Patent No. 247,771, dated October 4, 1881.

Application filedMay25, 1880. (No model.)

To all whom it may concern:

Be it known that 1, HARRISON Lonme, of Boston, in the county of Suffolk and State of Massachusetts,haveinventedcertain improvements in wire mats used in extracting juice from Meets or other substances from which juice, oil, or other liquids are extracted by means of pressing, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawlugs.

My invention consists, mainly, first, in the arrangement of the wires ot' which the mats are constructed so that they shall all radiate from the center, which gives to themats great strength and the largest amount of conducting-snrt'ace, also conducting the liquid uniformly in the most direct manner from center to periphery; second, in introducing a sealring under the plunger to prevent the exuding of matter around the sides of the plunger.

In the drawings, Figures1 and 2 are elevations, and Figs. 3 and 4 cross-sections, of two forms of mats,diti'eriug in the methods of leading the wires from the center.

In Fig. 1 I show a ring, I), made of iron, steel, or other metal, around which the wires are taken to be used where an open center is desirable. In other cases I use a circular plate, 0, Fig. 2, with holes drilled around the edge, through which the wires are passed. Theouter ring is formed in both cases by a welded metal hoop, a a.

Fig. 5 shows a transverse section of a curb with mat, seal-ring, and plunger in place, A A being the staves and hoops of the curb; B, the plunger; 0, bottom of curb D, section of mat; E E, cross-section of seal-ring in its place under the plunger E E.

Fig. 6 is a half-plan view of the seal-ring. This may be entirely separate and detached from the plunger or connected to the same in a manner to allow lateral motion, the outside of the ring being very nearly the same as the inside diameter of curb, whereas the plunger must be made somewhat smaller, to allow for unsteady motion or inaccurate setting of the curb.

It is practically impossible to make the plunger tit snugly inthe curb. and one feature of my invention is the combination of the sealring with the curb and plunger, the efi'ect being the same, so far as concerns preventing the material exuding between the plunger and curb, as if the plunger were a snug fit in the curb, while at the same time all the'disadvantages of having the plunger tit-snugly in the curb are done away with by neason of the fact that the seal-ring is not fast to the plunger, but is capable of moving slightly under the plunger during the pressing operation.

Another feature of my invention is torlning the mat of a large number of wires arranged in bundles orlayers twisted tOg6tll8l,Ht"l'l bundle being also arranged radially and secured at the center and at the circumference of the mat.

\Nhat I claim as my invention is- 1. The improved wire mat embracing in its construction a number of bundles or layers of wire, each bundle or layer being arranged radially and fast atthe centerand atthc circumference of the mat, substantially as described.

2. In combination, the curb, the plunger, and the seal-ring, substantially as described.
