BED-BOTTOM FABRIC.

Specification of Letters Patent.

Patented Mar. 26, 1912.

Application led November 1, 1911. Serial No. 657,961.

Fabric, of which the following is a speciication.

This invention relates to a bed bottom fabric of novel construction, which is of great strength and may be readily folded. The main body of the fabric is composed of a plurality of links of like construction which can be assembled in a quick manner and do not require to be clenched or otherwise fastened after being interhooked.

In the accompanying drawing: Figure 1 is a plan of a bed bottom embodying my inventiong`F ig. 2y a plan of a section of the bed bottom; Fig. 3 a longitudinal section on line 3-3, Fig. 2; Fig. 4 a perspective view showing the position of a pair of links while being interhooked, and Fig. 5 an enlarged cross section on line 5 5, Fig. 1.

Each wire link of the bed fabric is substantially U-shaped with parallel shanks 10 that join the cross bar 11 at right angles. At its free end, each shank 10 is upset to form a closed elongated'eye 12. The cross bar 11 is straight with the exception of a central recess or bend 13 anda pair of end recesses or bends 14, the lat-ter extending in the same direction as recess 13 and being flanked by the shanks 10. The links constructed. as described are so placed as to form a series of transverse rows, the links in any one row being staggered with the links of the adjoining row. The links that are placed sidewise of each other are not directly connected, but they are connected to the links of the succeeding row in such a manner that the central recess 13 of any link in one row is engaged by the Shanks 10 of two adjoining links in the next row as clearly illustrated in Fig. 2. In order to effect this assemblage, the two links to be` connected are placed at an angle to each other, so that the eye 12 of one link may be passed freely through the eye 12 of the other link (Fig. 4). This connection is feasible for the reason that the length of each eye is so much greater than its width, that two eyes of equal size may be threaded by placing one eye at right angles to the other. After the links have been connected in the mannerdescribed, the body of the irst link is slipped through the eye of the second link, until the central recess 13 of said first link becomes engaged by said eye. In this way all the links may be readily interlocked to become permanently united without requiring any objectionable upsetting of the parts after the assemblage thereof.

The first transverse link row of the bed bottom is secured to the corresponding end rail 15 by means of a number of springs 16 each hooked at one end into said rail and carrying at its other end a duplex hook 17, each engaging a pair of adjoining shanks 10. The last transverse link row of the bed bottom is connected to the corresponding rail 18 by a plurality of coiled-springs 19 engaging said rail at one end and carrying at their other end, duplex hooks 20 engaging outer recesses 14 of adjacent links. It is obvious that alternate transverse rows of links contain one link more than the intermediate rows. The two flanking links of those rows which contain-this eXtra link are connected to the two flanking links of the next row containing such additional link by means of wine rods 21 having an eye 22 at one end and a hook 23 at the other end. Of these, eye 22 engages one of the end recesses 14 of the opposed cross bar 11 while hook 23 is passed through the eye 12 of the opposed shank 10*l and is then closed.

n It will be seen that the bed bottom con structed as described, may be readily assembled without protracted manipulation. Owing to its foldable nature, it is well adapted for folding beds, while it may also be used for lounges, easy chairs or similar articles.

I claim: t

1. A wire fabric composed of parallel series of substantially U-shaped links having lateral shanks with terminal eyes and a connecting cross-bar having central and end recesses, the shank-eyes engaging the central recesses of adjoining linksin one adjacentA row, and the central recess of the cross-bar being engaged by the terminal shank-eyes of adjoining links in the opposite adjacent row, and a number of wire rods engaging the marginal end recesses of the cross-bars.`

2. A wire fabric composed of parallel series of substantially U-shaped links having lateral shanks with elongated terminal eyes and a connecting cross-bar having central number of Wire rods engaging the marginal and end recesses, the elongated shank-eyes end recesses of the cross-bars.

engaging the central recesses of adjoining links in one adjacent row, and the central recess of the cross-bar being engaged by the elongated terminal shank-eyes of adjoining links in the opposite adjacentrow, and a JACOB OHAVES. Witnesses:

ARTHUR E. ZUMPE, KATHERYNE KOCH.
