Divided and this application filed September 25, 1914. Serial No. 863,479.

To all whom it may concern:

Be it known that I, J AGUB SCHWARTZMAN a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in lVire Fabrics, of which the following is a specification.

This invention relates to wire metallic fabrics, the object of the invention being to provide an improved fabric of this character particularly adapted for use in connection with spring mattresses, which will be simple in construction, durable in use, and comparatively inexpensive to manufacture, especially in View of the fact that it requires a minimum amount of wire in its construction, made up of an improved form of links, quickly and inexpensively assembled, and in which the pull ,on the several links of the fabric will be in a straight direction lengthwise of the fabric, and which links are so constructed and assembled that they will not draw the edges ofthe fabric toward the middle by reason of the lengthwise pull on the links, while at the same time the fabric will be unusually resilient and may be readily folded along longitudinal lines, which is desirable when the fabric is to be applied for use in folding cots, divans and other folding structures.

The present improvement is a, division of my Patent No. 1,116,500, dated November 10, 1914. s

In the drawings accompanying and forming part of this specification, Figure 1 is a plan View of a plurality of links of the exact size as usually used, assembled; Fig. 2 is a plan view showing the improved fabric made up of a number of units or links; Fig. 3 is a detail view, full size, of one of the improved links for the body of the fabric; Fig. 4 is an edge view of the link shown in Fig. 3; and Fig. 5 is a detail View illustrating another way of assembling the same form of links, the links being shown full size.

Similar characters of reference indicate corresponding parts throughout the several figures of the drawings.

In the form shown, the fabric is made up of a series of interconnected or interwoven units or links 2, each comprising a pair of relatively

straight portions

3 and 4 running in substantial parallelism with each other and connected at their ends by a cross-forming portion 5, thus forming a link somewhat resembling a capital letter U.- The

straight portions

3 and 4 of the link terminate in hooks or loops 3 and it respectively at one end of the link, these hooks being in alinement with the straight portions and are closed when the link is made; in other words, before the links are assembled and notsubsequent to the assembling of the links. At the opposite end, or what may be considered the head portion, of the link, each of these lengthwise extending portions v3 and 4 merges into an angular-formed portion 6 made up of a pair. of

inclined portions

7 and 8, each of which may be slightly curved, which inclined

portions

7 and 8 at their juncture points are offset one from the other as at 9, that is, it is given a half twist whereby the several links may be readily interwoven with each other, the inclinedportion 7 in turnbeing bent inwardly as at 10 to form an eye or loop 11 of somewhat triangular form and therefore resembling some what the shape of an. inverted V, such loop or. eye terminating in the cross member 5. Each angular formed portion extends'outwardly so that the link at this point is of greater width than at any other point thereof, while the cross member 5 is located inwardly of the extreme end of the linkand is comparatively short, and the straight por-.

tions 3 and 1, if continued, wouldmerge into the inclined portions 10 relatively close to the outer ends of the cross portion 5. In short, the head of each link is considerably, wider than the space between the

straight portions

3 and 4 thereof for the purpose hereinafter stated. The angular portions of the link hereinbefore described are for the purpose of permitting an efiicient and effective interlocking or interweaving of one link with a companion link in the manner shown in Figs. 1 and 2, in which it will be observed that the companion links or units are, as it were, twisted together, this being permitted by reason of the offset portions 9 of each link which'constitute the connecting part between the inclinedportions forming the triangular portion of the link at this point.

When the several units or links have been assembled in the manner shown in Figs. 1

and 2, they are connected to a supporting or cross-angle bar by helical springs 13, for

which purpose intermediate end links 14 are provided with hooked ends 15 for connection with the eyes 11 of the several links.

In the form shown in Fig. 5 the units or links instead of being connected or interwoven directly, are connected by meansof a ring 16 which is interwoven with the triangular portions of the link. It will be observed that by means of the present improvement, the pull on the links is in a straight direction lengthwise thereof and that the straight portions 3 and A are not only spaced from each other in each link, but the adjoining straight portions of the several links are likewise spaced from each other a considerable distance, as at 17, and that although the space between the straight portions of a pair of adjoining links is not as great as the space between the straight portions of each link, yet it is sufficiently great to give increased support to the stuffed mattress placed upon the fabric. In other words, by reason 'of the fact that the straight portions of adjoining links are spaced apart a considerable distance, increased support is given to the mattress, as will be obvious as compared with the support which is given thereto should such straight portions be brought close together, for in such latter case a pair of links, for instance, would support the mattress practically only at three points, whereas in the present instance the mattress is supportedat four points. Moreover, by reason of the fact that the hooks of each link are in alinement with the straight portions, there is no appreciable tendency of the links to draw the edges of the fabric toward the middle and present an uneven edge, which is always a serious disadvantage in any fabric. Moreover, by reason of the fact that the hooks of each link are practically completely closed when formed, and before the fabric is assembled, the links can be quickly interwoven, and furthermore when the links are tinned, the tinning material connects the hooked end with the adjacent portion of the link, thus forming practically an integral loop.

By reason of the present improvement considerable resiliency is obtained both lengthwise and sidewise of the fabric.

One of the advantages, as hereinbefore stated, for the present improvement, is that the links may be quickly and readily formed by machinery just as shown in the drawings, that is with closed hooks or loops, and readily and quickly assembled by inexpensive labor, thus avoiding the necessity of bending the ends to form the hooks subsequent to the assembling of the links.
