inseam.
To all whomit may concern:
Be it known that I, VVINFIELD SCOTT Po'r- 'rnn, a citizen of the United States, residing at Pittsburgh, county of Allegheny, State of Pennsylvania, whose post-office address is Manufacturers Building, Duquesne Way, Pittsburgh, Pennsylvania, have invented certain new and useful Improvements in Screens; 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 appertains to make and use the same.
In an application for Letters Patent of the United States filed by me, of even date, herewith, I have described and claimed a metallic screen made up of interwoven wrought metal bars having abrupt depressions or indentations at the points of crossto interlock the intersecting bars against displacement, and thereby assure accuracy of mesh throughout the life of the screen. My present invention relates to a screen of this general type, and particularly to a screen wherein the intersecting bars have arched sections between the crossing points, so as to produce screen orifices having curved outlines, said screen orifice being either circular or generally rectangir lar with rounded ends or corners.
In the accompanying drawing, Figure 1 represents a top plan view of a portion of a screen made in accordance with my present invention, Fig. 2, represents a sectional view on the line 2-2 of Fig. 1; Figs' 3 and 4, represent respectively a top plan view and a side elevation of a portion of one of the wrought metal bars employed in making up the screen; Fig. 5 represents a top plan view of a portion of the screen made in accord ance with the invention, but wherein the screen orifices are generally rectangular with rounded ends instead of being circular.
Similar letters of reference indicate similar parts throughout the several views.
Referring to the drawings, it will be noted that, as the screen of myco-pending appli cation for Letters Patent above referred to," the screen of the present application is made up of interwoven wrought metal bars, which ing adapted Specification of Letters Patent.

are preferably of high grade wear-resisting material, such for example, as manganese cated in the drawing and as will be readily understood by those skilled in the art.
It will be noted, as hereinbefore indicated, that both the underlying and the overlying bars have arched portions between the cross- I ing points, so as to produce screen orifices having curved outlines. In the form shown in Fig. 1, the screen orifices due to this curvature are circular. In the form shown in Fig. 5, however, the screen orifices, while of circular curvature at their ends are of general oblong configuration. Screens having circular orifices and screens having oblong orifices, have special uses in the arts, particularly for the screening of crushed stone, ores. grave], coal, coke, and the like, and, when lat surfaced, as contemplated by my invention, are of especial merit for certain purposes. it 'will be further understood that after the screen is woven flat, it may be rolled, as a whole, to any desired curvature, so that. in this, way, for example, cylindri cal lu'OlVifiQ screens, which are now widely used can be cheaply manufactured and can be given great strength and durability.
\Vhat I claim is:
1.- A screen made up of interwoven wrought metal bars shaped to present at the points of crossing abrupt recesses or depressions securely interlocking the intersecting bars against displacement, the underlapping and overlapping bars having arched sections between the crossing points to produce screen orifices havingcurved outlines.
