WOVEN STRUCTURAL MATERIAL Filed Dec. 1. 1955 INVENTOR. SAWYER M. POMEROY ATTORNEYS United States Patent- WOVEN STRUCTURAL MATERIAL Sawyer M. Pomeroy, Lyndhurst, Ohio, assignor to The cihTyler Company, Cleveland, Ohio, a corporation o Application December 1, 1955, Serial No. 550,398 4 Claims. Cl. 139-425 rial is that it is woven in a mannerto provide certain highlighting surfaces and one in which the woven structuralmaterial appears to have multiple surfaces, i.- e., an exterior surface f ormed by a multiplicity ofovaloid sections; in a precrimping operation, a second surface formed by the cross strands, possibly bars, and other surfaces formed by the grouping of strands between said.

surfaces to give a truly textured surface to the woven structural material and still one of innate attractiveness. The structural material is formed by precrimping the section adjacent the cross strands and forming on one face thereof which is opposite to that of the cross strand, an ovaloid section. The material itself is slightly bent over the cross strand. The opposite face is formed in any manner in order that it will fit with the cross strand and in some cases it might be slightly curved, but in any event the cross section would be elongated.

An object of this invention is to produce a new and improved woven structural material particularly useful in interior building panels.

A further object of this invention is to produce a new and improved woven structural material which permits a certain separation between the strands and provides for various surface treatments that will make highlights and shadows that may be treated in other manners to bring out its special features.

To the accomplishment of the foregoing and related ends said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims; the following description setting forth in detail one approved means of carrying out the invention, such disclosed means, however, constituting but one of the various ways in which the principles of the invention may be used.

In the drawings:

Fig. l is a longitudinal cross sectional view of this invention;

Fig. 2 is a view along the lines 2-2 of Fig. 1, axially of the cross strands;

Fig. 3 is a view along the lines 3-3 of Fig. 1, axially showing the intersection between the various groups of longitudinal strands;

Fig. 4 shows a plan view of said groups of longitudinal strands, 3 longitudinal strands being shown together; and

Fig. 5 is a fragmentary view of 2 strands, one longitudinal and one cross strand, showing in a large form the ovaloid section at the intersection.

2,874,730 Patented Feb. 34, 1 959 ice In saiddrawings 10 in Fig. 1 indicates a single longitudinal strand and 11 indicates another longitudinal strand. In each case there may be 3, 4, or 5 longitudinal strands woven together. 12 indicates the cross strand and 13 indicates another cross strand. Allof the strands will not be numbered as it is only necessary to illustrate the principal features of the invention. In Fig. 1 it can be seen that each of the longitudinal strands are precrimped prior to weaving in the woven structural material. Precrimping operations flatten one section of the longitudinal strands and partially flatten the opposite face thereof. One face then forms an ovaloid section, as is particularly seen in connection with Fig. 4, and the enlarged portion of Fig. 5. The ovaloid section is shown at 14. The opposite section of the longitudinal strands would be shown at 15, particularly in Fig. 5, and this is seen in the cross-sectional view of Fig. 1 at 16. The side view as seen from Fig. 1 shows the flattened surfaces as seen at 17.

The effect of precrimping these wires and weaving them in the manner indicated is to produce a grouping of longitudinal strands having ovaloid sections and said groupings appear to form a single plane.

Although in the past wires have been formed in various ways and sections have been flattened both axially of the strands and cross strands have been flattened in the manner indicated, they do not appear to be formed in the manner with groups of ovaloid sections in thelongitudinal strands. Of course, it will be understood that though the strands are indicated as being longitudinalstrands, this is only for purposes of reference, and they could be arbitrarily designated cross strands.

It is clear, as seen in Fig. 2, that four strands as shown at 18, 19, 20 and 21 are above the cross strands .13. The next four are under, and this is the general pattern of this particular weave.

Fig. 3 shows the cross section .along the lines 3-3 of Fig. 1 and, of course, at this point the strands are slightly angulated one up and one down. It is important to note that this particular manner of weaving produces what will be seen on the right portion of Fig. l.

The ovaloid sections previously indicated and shown in Fig. 5 at 14 form a multiplicity of ovaloid sections, and these are reproduced in a uniform manner. These produce a single plane which is designated at 22, and the cross strands which form this Weave produce another plane, and the general level of this plane will be indicated at 23 for said cross strand. At the same time the surfaces forming the longitudinal strands produce another plane indicated at 24 and a further plane indicated at 25.

It is readily apparent that when these longitudinal strands are formed in groups of strands, perhaps 3, 4 or 5, they extend over and under the cross strands and have by means of this precrimping operation a distorted cross section at the portions contacting and generally overlying the cross strands, and the ovaloid sections extend along the longitudinal strands. This distortion formed by flattening of the strands at the portions contacting or overlying the cross strands produces a portion of greater width than the remaining portions of the strands and as a result, these longitudinal strands when held in abutting relationship space the remaining portions of the strands from each other.

These may be treated in various ways as by polishing, by oxidizing the material, which may be brass, steel, aluminum, stainless steel, or combinations of these materials, and after treatment in one way, one or more of these surfaces, particularly thesurface 22, may be polished or oxidized in a single direction to produce unusual effects.

. Although the present invention has been described in connection with a few preferred embodiments thereof, variations and modifications may be resorted to by those skilled in the art. Without departing from the principle of the invention, all of these variations and modifications are considered to be within the true spirit and scope of the present invention as disclosed in the foregoing description and defined by the appended claims.

I claim:

l. A woven structural metal material formed of longitudinal and cross strands, said longitudinal strands being arranged in a plurality of groups which extend over and under the cross strands, each longitudinal strand in said groups having an enlarged flattened portion at the junction with the cross strand, the width of said flattened portion being greater than the remaining portions of the longitudinal strands, whereby said flattened and enlarged portions space the remaining portions of the longitudinal strands from each other.

2. A woven structural metal material formed of longitudinal and cross strands, said longitudinal strands being arranged in a plurality of groups which extend over and under the cross strands, each strand in said groups having a distorted cross section at the portions contacting the cross strands and extending along the longitudinal strands, said distortion being formed by flattening the strands at the contacting portions and expanding the same laterally to a width greater than the remaining portions of the strands and into abutting relationship, whereby said flattened and enlarged portions space the remaining portions of the strands from each other.

3. The process of making a woven structural metal material formed of longitudinal and cross strands, said longitudinal strands being woven in a plurality of groups of strands which extend over and under the cross strands, which comprises flattening and expanding each of the longitudinal strands at spaced points and interweaving said longitudinal and said cross strands whereby the flattened portions of the longitudinal strands are positioned at the points of intersection of said longitudinal and cross strands, said flattened portions spacing the remainder of the adjacent strands of each group from each other.

4. The method ofclaim 3, in which the expansion of the strand adjacent the cross strand is formed by crimping the strand and flattening one portion forcing the material outwardly where it will be in abutting relationship with the adjacent longitudinal strands in a group of strands.
