WIRE FABRIC.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed May 13, 1914. Serial No. 838,267.

To all whom it may concern:

Be it known that I, FREDERICK A. ZIELKE, citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of Vvisconsin, have invented certain new and useful Improvements in Wire Fabrics, of which the following is a specification.

The invention relates to a mattress fabric of formed wire, the object being to provide a simply constructed fabric and offer a resiliency desired in this class of goods.

In the drawings Figure 1 is a perspective View of a section of the completed fabric; Fig. 2 a detail showing the means of linking; Fig. 3 an edge view of the same; Fig. la detail showing the form of the links; and Fig. 5 is a view of a modified form of the large links.

The numeral 1 shows the usual supporting rail to which are secured the specially formed wires 2 which are kinked or looped at 3 at spaced intervals, all the loops facing in the same direction, the ends of the wires 2 being stretched and secured firmly to a suitable frame composed of rails 1, the strands being spaced apart equidistantly along the length of the rails.

Specially formed links of U form are fitted to connect or cross tie the strands 2 laterally and consist of wire 4 formed with eyelets 5 at each end which are spaced apart equal to the spacing of the loops 3 and are hooked over the point of the said loops and closed to form a substantial flexible joint. The center portion of each link is formed with a corner loop 6, being bent outwardly and laterally leaving a straight portion 7. Figs. 3 and 4: illustrate the lateral bend of the looped corner 6. The straight portion 7 rests parallel with the looped strands 2 and in close proximity thereto. It will be seen that this form of looping ofiers great elasticity, for when pressure is brought to bear on the fabric the spring is taken by the various bends in the link at 6 and the loops 3, the latter being held from spreading by the passing therearound of the link cor ners 6 which draw in on their circular portion and tend to resist the spreading of the loops 3 thereby giving abundance of spring to the whole fabric.

Insome cases it may be desired to pass the link around one loop instead of a pair of loops as shown in Fig. 5, in which case the same link is used but of less space between V the legs 4: so the two eyelets can be connected with one loop of the adjacent strand.

What I claim is 1. A wire fabric comprising a plurality of spaced wire strands, the strands being formed to provide a series of loops spaced throughout their lengths, means for cross tying the looped strands together consisting of a plurality of U-shaped loops having enlarged space *at their corners'and having the corners bent laterally, the said U-loops being hooked to a pair of loops of one of said strands and having their enlarged corners passing around a pair of loops of an adjacent strand, the cross portion of the U-loop being positioned in close proximity to the looped strand.

2. A wire fabric consisting of a plurality of spaced wire strands having a series of spaced loops therealong, U-formed links passing around the loops of one strand and having their ends connected to the loops of an adjacent strand, the links having enlarged corners and formed laterally with relation to the plane of the fabric and a cross member positioned parallel with the first said strands.

In testimony whereof I affix my signature, in the presence of two witnesses.

FRED. A. ZIELKE.
