zen. of; the; United; States, residing ati. Ghicago, inthe county; of-Oook; and State. of

Illinois, have invented; alnew and useful Corrugated-Link Bed Fabric, .of; which the fOllOWin-gis a specificationa One object ,of; thejpresentinvention is. to

view: which: will: appear as the description proceeds, the invention resides in the come bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 shows one form of the invention in top plan; Fig. 2 .,is a section on the line 22 of Fig. 1; Fig. 3 is a section on the line 33 of Fig. 1; Fig. 4 is a top plan showing a modified form of the invention; Fig. 5 is a top plan showing a still further modification in the invention; Fig. 6 is a section on the line 66 of Fig. 5; and Fig. 7 is a plan depicting another modification.

In carrying out the invention there is provided a link which is fashioned from a single strip of material bent upon itself to form a terminal eye 1, the link being corrugated to form intermediate eyes 2, and to form straight parallel arms located between the eyes and indicated by the reference character 3, the extremities of the strip being bent to form hooks 4 disposed in parallel relation and positioned at right angles to the plane in which the eyes 1 and 2 are located. These eyes 2 constitute outstruck parts which alternate with the contacting arms 8 and serve to stiffen the links between the ties hereinafter referred to. The hooks A of one link are engaged with the terminal eye 1 of an adjoining link, as clearly shown in Fig. 1. Any desired number of lines of links may be employed, and the several lines of links may be connected in a variety of ways, as will hereinafter appear.

In Fig. 1, the lines of links are connected by alined cross ties, each comprising converging; parts 5.: terminatedEin hooks '6 which are engagedwith;,theastraighti paralleli arms.

At one s 1de;0.f;the.bed;, thebendfl in thelink is fashioned. 1ntj0;a--. hook aseshownv at. 8', the hook :8 engaging the arms-32, between-the ad+ ]ace11tlne.yeStI2 The cross ties may be located at any desired; points= along.v the: links; and: referring tOJTEIg. 4, it will be observed that the hooks 6 of each cross tie may engage with the hooks 4 of a link, the relative positions of the remaining parts being otherwise unchanged.

As shown in Fig. 5, the cross tie may comprise converging arms 9 uniting at one end to form loop-shaped hooks 10 engaged between the eyes 2. At their free ends, the arms 9 terminate in hooks 11, engaged around the straight parallel arms 8, between the eyes 2 and within the contour of the loop-shaped hooks 10.

In those forms of the invention shown in Figs. 1, 4 and 5, the cross ties are shown in alined relation. The cross ties, however, may be disposed in alternating relation, as shown in Fig. 7

In Fig. 7 each cross tie is shown as comprising converging arms 12, united at one end to form a loop-shaped hook 14, the free ends of the arms 12 terminating in hooks 15, the hooks 14 and 15 being engaged with the straight parallel arms 3, between the eyes 2.

Special attention is directed to the fact that each link is corrugated to form a plurality of eyes and to form straight parallel arms between the eyes. Owing to this construction, the links will not become distorted, and the fabric will not sag unduly, even under a great weight. Further, the links are well adapted to permit the cross ties to be mounted at any points between the ends of the links. Owing to the fact that the links are expanded to form the eyes 2, the bearing area of each link is increased, and it is possible to omit, in a bed of ordinary size, two or more lines of links, with out appreciably decreasing the supporting surface, and without markedly impairing the supporting qualities of the bed fabric.

Having thus described the invention, what is claimed is:

1. In a bed fabric, a plurality of links, each fashioned from a single strip of material bent upon itself and corrugated to form a terminal eye and intermediate eyes and straight parallel arms between the eyes, the free ends of each strip terminating in parallel hooks engaged in the terminaleye of'an adjoining link, and cross ties connecting the parallel parts of the links. 1

2. Ina bed fabric, lines of links having corrugations; cross ties each having at one end a hook and having at the other end a loop abutting terminally between, and held against lateral movement by, the corrugations of another line, the hook 0f anadjoin ing tie being engaged with said loop and bein engaged between said corrugations.

3. A wire bed fabric comprising cross ties and links united by the cross ties, the links having a plurality of laterally extended eyeforming portionslocated between a pair of adjacent cross ties to increase the supporting area of each link and to avoid a straight cutting edge in each link between a pair of 7 adjacent cross ties.

4. A wire bed fabric comprising cross ties and links connected by the cross ties, the links comprising opposed parts provided between a pair of adjacent cross ties with straight, parallel, contacting portions and with continuously curved outstruck parts al- I I GARY B. SMITH.
