BED-BOTTOM WIRE FABRIC.

Specication of Letters Patent.

Application led February 28, 1916. Serial No. 80,838.

To all whom t may concern Be it Vknown that we, CHARLES J. KINDEL and JOSEPH DELANEY, citizens of the United States, respectively residing at Grand Rapids, county of Kent, and State of Michigan, and Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Bed-Bottom ViI-e Fabrics, of which the following is a speci-V cation.

This invention relates to woven-wire bedbottoms, and contemplates the production of a wire-fabricwhich, preferably, shall possess the `desired amount of resiliency and, at the same time, an inherent limit to undue sagging.

The invention, therefore, consists in the formation and combination of parts, prefthe purposes specified, substantially as hereinafter set forth and particularly pointed out in the claims. Y

Referring to the drawing: Figure 1 is a. fragmentary view in plan of my improved wire-fabric bed-bottom; Fig. 2 a similar view of one of the principal links in detail; and, Figs. 3 and 4; illustrate two modifications of the principal links.

Similar numerals of reference indicate similar parts in all the figures of the draw- In rglhe fabric is composed of a number of parallel series of principal links longitudinally disposed and connected. For the purpose of illustration, we have shown three such series, the same being numbered, respectively, 5, 6 and 7. The links of the series, or what we term, for convenience, the principal links, are indicated at 8, and the minor or cross-links, employed for joining the principal links of a series with the corresponding links of the adjacent series, are indicated at 9.

The link 8 is formed by bending a blank of, preferably, spring-wire upon itself, and at its middle, to form a flat coil 8a, two turns of the blank constituting 'a suiiicient coil. At each side of the coil occur terminals or legs l0, and these preferably extend from said coil at opposite sides thereof and practically in the same plane, the planes being varied merely by the thickness of the wire. Between their ends, the terminals are outwardly and oppositely bowed, and if formed of spring-wire, said terminals will straighten .under stress until straight and practically parallel which, will, of course, be their limit of expansion. The bowing of these `terminals may be increased or diminished from that shown. The legsflO finally terminate inv abrupt hooks,11,'those of one pair of terminals or legs engaging the coil or eye 8'C1 of the next succeeding link of the series. The cross-links, or as we have termed them, the minor-links, may be of any desired form, but are preferably capable of yielding, and therefore, formed of a blank of spring-wire bowed or curved sufliciently to result in the desired amount of resiliency in the finished fabric. Each cross or minorlink terminates in abrupt hooks 12, which engage the eyes or coils 8a of the adjacent principal links of adjacent series.

Both the cross or minor-links and also the principal-links are capable of modification without sacrificing the advantages of our invention, and as an illustration, we have illustrated in Figs. 3 and 4 of the drawing, two simple modications of such principallinks. In Fig. 3, the terminals or legs cross immediately below the eye or coil, as indicated at 10a, while in Fig. 4, the terminals or legs are positioned close together immediately below the eye or coil by means of abrupt rentrant curves 10b. However, in

any of these forms of principal-links, and

also in many others that may be readily devised upon this principle, the longitudinal resiliency is limited by the legs or terminals straightening under stress, after which, no further sagging of the fabric can occur. Upon a removal of the stress, the legs or terminals, as will also the crossor minor-links, will resume their normal or bowed condition.

Having described our invention, what we claim is:

1. A wire fabric bed-bottom, consisting of a plurality of similarly and longitudinally disposed Straight paralleLseries of principal-links, each link of said series consisting of a piece 'of spring-wire coiled upon itself at its middle to form an eye and extended beyond the same to form plain bowed terminals extending in the same direction as and inclosing said eye, said terminals terminating in hooks, the two hooks of each pair of terminals engaging the same eye of the next succeeding link of the same longitudinal series, and cross-links, terminating in hooks, engaging those eyes of the opposite links of adjacent series with which the terniinals of the principal-links engage.

A Wire fabric bed-bottom, consisting of a plurality of similarly and longitudinally disposed straight parallel series of principal-links, each link of each series consisting oi' a. piece of spring-Wire coiled upon itseltl at its middle to forni an eye and extended beyond the same to form plain oppositely looWed terminals extending in the same direction as and inclosing said eye, said terniinals terminating in hooks, the two hooks of each pair of terminals engaging with the saine eye of the next succeeding link of the saine longitudinal series, and bowed cross- Copies of this patent may be obtained for ve cents each, by addressing the links, terminating in hooks, engaging those eyes of the opposite links ot' adjacent series with which the terminals of the principallinks engage.

In testimony whereof We afiix our signatures in the presence of two Witnesses.
