OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No.'296,601, dated April 8, 1884.

' Application filed December 3l, 1883. (No model.)

To CLZZ whom z' may concern:

Beit known that I, Annrnnnr E. Osnonn, a' citizen of the United States, residing at vWaco, in the county of MacLennan and State of Texas, have invented new and useful Improvements in Oil-Press Mats, of which the following is a specification. i

This invention relates to improvements in the oil-press mat for which Letters Patent No. 285,300 were issued to me September 18, 1888, and has for its objects to simplify and reduce the cost of manufacture and improve the construction of that cla-ss of mats, and to provide a novel hinge for the leaves of the mat for connecting them and preserving their parallelism when the meal is placed between them and subjected to the action of a press.

To such ends my invention consists in a mat for oil-presses having its leaves composed of paper-pulp molded by dies or molds into the requisite shape to present'ahard and inelastic body to the meal to be pressed, said leaves of molded s paper-pulp being provided with a leather backing.

The invention also consists in an oil-press mat the leaves of which are composed of pal per-pulp molded by dies or molds into a hard and compact body, to present an inelastic surface to the meal to be pressed, said leaves being backed by leather and connected by a hinge ofthe constructionhereinafter described and claimed, whereby the leaves are connected and their parallelism maintained when placed face to face in a press.

The invention is fully illustrated i-n the accompanying drawings, in which Figure l isa plan view of the mat with the leaves spread open; Fig. 2, alongitudinal sectional viewwith the leaves folded together; Fig. 3, a view like Fig. 1, showing the leaves without transverse corrugations and ribs, and Fig. el a sectional view of Fig. 3 with the leaves folded together. Referring to the drawings, it will be seen that the mat is shown as composed of two leaves, each leal comprising a body, 1, which is formed by molds or dies under pressure into a hard and compact sheet, preferably with converging side edges, all in such manner that the paper-pulp body presents a hard and inelastic surface to themeal to be pressed.

During the process of molding the paperA pulp leaf it may be provided with transverse corrugations, forming ribs 2, and longitudinal edge beads, 8, as in Figs. 1 and2; but the face of the leaf maybe plane, with edge beads, 3, as in Figs. 3 and fl. After each leaf has been molded from paper-pulp bya mold or die into a hard, compact, and inelastic body, it is secured to a strip, 4, of leather by any suitable means-such as nails, screws, or cement-and this leather baclringis continuous between the two leaves to form a flexible connection, 5.

The handle for carrying the mat is composed of a single strip, 6, of leathenwhich is secured at its ends to the edges of the leather backing at the llexible connection 5, and to such strip 6 is secured the knuckle-joint 7 of two hingeleaves, S S, to the outer edges of which are hinged plates 9 9 by knuckle-joints 10, said plates being rigidly` attached by screws or otherwise to the widest and adjoining ends of the molded paper-pulp leaves, thus constituting a triple metallic hinge-connection, which. obviously permits the leaves to uniformly' approach each other when in the press, and preserves their parallelism when pressing and shaping the meal into cakes, while at the same time the leaves can be spread open, as in Figs. 1 and 3, to permit the meal and its bag or covering to be properly placed in position.

B y the employment of paperpulp and molding it by dies or molds into a hard and compact leaf, I produce a superior mat at less eX- pense and labor than by the means set forth in my patent alluded to, and, besides, I am enabled to dispense with the sheet-metal faceplates, for the reason that the paper-pulp can be molded into such hard and compact shape as to present the requisite rigid and inelastic surface to the meal to be pressed and shaped.

Ihe leather backing of the molded paperpulp leaves preserves them from being broken or injured in the press and imparts great durability to the structure.

Having thus described my invention, what I 9 5 1. An oil-press mat composed of molded paper-pulp leaves hinged or jointed together, each leaf being provided with an attached leather back, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing idly attached to the mat-leaves, substantially witnesses. as described.
