BED-BOTTOM FABRIC.

Application filed September 20, 1927.- erial No. 220,681.

The purpose of this invention is to provide a wire mattress fabric, especially adapted for folding cots, which will have a limited amount of resiliency in its strands, permit ting the fabric to'be stretched endwise over the cot frame,v avoiding the DQCGSSHLY for springs, and which will have smooth finished side edges. A further purpose of the inven tion is to provide end bars of light construction andhaving means whereby the fabric may be securely and inexpensively connected. to it, said end bars serving as a means for detachably connecting the fabric to the cot frame.

The fabric of the present application is shown in my co-pending application, Serial Number 75,995, filed December 17, 1925, but not claimed therein.

In the accompanying drawing,

Fig. 1 is a top plan view of the fabric and end bars, the side rails of the cot frame being also shown;

Fig. 2 is an enlarged detail View of a portion of the fabric; and,

Fig. 3 is a section on the line 33 of Fig.

The fabric comprises a plurality of similar wire strands, a, b, a, (2, etc., each bent to form a succession of relatively narrow loops, opening alternately in opposite directions, the loops of the strand a being indicated at 1 and 2; those of the strand 1) being indicated at l 'and 2*, and those of the strand 0 being indicated at 1 and 2. The sides 4 of the loops of each strand are parallel, and the closed ends 5 of the loops are substantially at right angles to the sides. In assembling the strands to form the fabric, the closed ends of the loops of one strand, as b, are hingedly connected to the closed ends of two adjacent strands, as a and c, by metal clips 6. Thus, when the closed ends of the loops of several strands are connected together by the hinge clips, the open ends of the intermediate loops, as 1*, 2, and. 1, 2*, will meet .and these meet ing loops form larger closed loops it of rectangular shape. The straight parallel sides of the loops stiffen the fabric lengthwise, but the fabric can stretch lengthwise to some extent because each right-angled loop end can yield to a limited extent when tension is put upon the fabric in the direction of its length. This avoids the necessity for connecting the fabric by springs to the end bars of the mattress. In order to give a smooth finish to the side edges of the fabric and to secure the ends of the several strands, the terminals of the, strands at the edgesof the fabric are bent to form'closed loopspas 3*, 3", and 8 Thus, the side 4? of the loop 3. has its end po'rtion'5 turned backwardly and thence upwardly-against theside 4 of the loop to which it is secured by a clip 7. Simiiarly, the side 4 of the. loop 3 has its end portion'5 turned backwardly and secured by a clip to the side 4 of the lo'op.' The loops 3 and 3? are hingedly connected by a clip 6, and theloops 3 and 3, which are similarly formedfare connected by a clip 6 I The end loops of all of the strands are alike, and the end loops of adjacent strands are hingedly connected together by clips, as shown. Thus, theends of the wires are all turned backwardly at the edges of the fabric to form closed loops and are secured by clips. Strong end loops are thus provided, the edge of the fabric is smooth, and the ends of the strands are held so that they cannot catch in the bed covers, or scratch the person handling the fabric.

The finished fabric is secured to light metal end bars 10, each having .a'series of tongues 8 punched out from the body of the bar. The

loops at the ends of the fabric are hooked over these tongues and the tongues are then depressed so that the fabric becomes securely fastened to the end bars, as shown in the drawing.

What I claim is:

1. A mattress fabric for camping cots, comprising a plurality of wire strands each bent to form a continuous series of similar loops, openingalternately in. opposite direcs tions, the sides of the loops being parallel and the ends of the loops being substantially at right angles to the sides, metal clips hingedly connecting the ends of alternate loops in each strand with the ends of alternate loops in an adjacent strand, the terminals of 1 each strand being the end loops of the ly connecting the of each end loop to the similar portion of an end loop in an adjacent strand.

2. A mattress fabric for camping cots, comprising a plurality of Wire strands each bent to form a continuous series ofsimilar loops, opening alternately in opposite direcbent backwardly, closing strand, and a clip hingedbackwardly bent portion tions, the sides of the loops being parallel I and the ends of the loops being substantially at right angles to the sides, metal clips hingedly connecting the ends of alternate loops in each strand with the ends of alternate inner sides, and a clip hingedly connecting the backwardly bent portionof each end loop to the similar portion of an end loop in an adjacent strand. i.

3. A mattress fabric for camping cots, comprising a plurality of Wire strands each bent to form a. continuous series of similar loops, opening alternately in opposite directions, the sides of the loops being parallel and the ends of the loops being substantially at right angles to the sides, metal clips hingedly connecting the ends of alternate loops in each strand with the ends of alternate loops in an adjacent strand, the terminals of each strand being bent backwardly, closing the end loops ofthe strand, and thence parallel with the inner sides of said end loops, the ends of the strandsbeing securedto said inner sides, and a clip hingedly connecting the backwardly bent portion of each end loop to the similar portion of an end loop in an adjacent strand.

4. A mattress fabric for camping cots, comprising a plurality of wire strands each bent to form a continuous series of similar -loops, opening alternately in opposite directions, means hingedly connecting the ends of alternate 100 s in each strand with the ends of alternate oops in an adjacent strand; the terminals of each strand being bent backwardly, closing the end. loops of the strand,

the ends of the strands being secured to the inner sides of the end loops, and means hingedly connecting the backwardly bent portion of each end an end loop in an adjacent strand.
