WIRE FABRIC.

Specification of LettersPatent.

Patented Apr. 6, 1920.

To all whom it may concern:

Be it lmown'that I, WILBER J. PINE, a citizen of the United States, residing at Oshkosh, county of Winnebago, and State of Wisconsin, have invented new and useful Improvements in Wire Fabrics, of which tend to retain a normal flat shape, to avoid undesirable general sagging of the fabric under load strain when used a mattress.

A further object is to provide a wire fabric of comparatively simple nature in which the above-mentioned advantages are secured, and which may be formed entirely of bent wire units of similar shape.

A still further object resides in the provision of a wire fabric unit formed of a single length of wire bent to provide both longitudinally and transversely extending portions, each portion having loops or eyes at its respective ends, loosely connected with otherunits in such a manner as to prevent displacement laterally of the plane of the fabric, while permitting limited play of each unit in all directions relatively to the others. With the above and other objects and advantages in view, my invention resides more particularly in the novel combination, formation and arrangement of parts hereinafter described and more particularly pointed out in the accompanying claims.

In the accompanying drawings:

Figure 1 is a plan View of a section of wire fabric constructed in accordance with my invention.

Fig. 2 is a sectional view through the fabric upon the line 22 of Fig. 1.

Fig. "3 is a view of a modified unit.

Referring now particularly to the drawings, my improved fabric comprises a series of similar T-shaped units having attaching eyes at the ends of their head and shank portions disposed in interlocking relation.

Each of these T-shaped units is formed of a single length of wire, one portion 5 of which is straight and adapted to be assembled in longitudinally extending position in the completed fabric. The portion 5 terminates at one end in an eye-loop 6 located in a vertical plane and also constituting one extremity of said length of wire. At the other end of the portion 5, the wire is looped in a horizontal plane to form an eye '7 and then extended across and above the portion 5 in the form of a transversely extending arm 8 looped upon itself to form a laterally projected horizontal eye 9 and reversely extended in the form of an arm 10 which again crosses the portion 5 (this time on the under side thereof), and is provided at its laterally projected extremity with another eye-loop 11 in a vertical plane. The portion of the arm 10 which extends underneath the shank portion 5 is depressed and forms a saddle 12 in which shank 5, adjacent to the loop 7, is supported resiliently, the arms 8 and 10 yielding under vertical pressures applied to'the shank 5.

Each unit, composed of the shank 5 and the arms 8 and 10 with the respective loops, is connected up with other units to form the mattress fabric by engaging each vertically disposed loop 6 in the horizontally disposed loop 7 of the next adjacent unit of a longitudinal series of like units, and each vertically disposed loop 11 is loosely engaged with the horizontally disposed loop 9 of another like unit in a transverse series of such units.

The eyes 6, '7, 9, and'll are sufiiciently large to allow a sliding movement in curved lines and to also allow resilient fiexion of the wire composing the eye, whereby the eye avoids any tendency to produce hard or unyielding spots in the fabric at the points where the units are connected with each other. By providing for the resiliently supported saddles 12, I am enabled to utilize longitudinally extending series of shanks 5 arranged substantially in line with each other but supported resiliently at numerous points by the transversely extending arms 10, each of which is not only held in position by the laterally adjacent units from which it is slung, but also by means of the partial engagement with the shanks 5 through the medium of the saddles 12. The arms 8 and 10 being integral and not being fixed to the shank portion 5 save through the loop 7 at an intermediate point, said arms constitute a head which is movable relatively to the shank but is held in position by the resilient loop 7. It is clear that any force applied to the fabric which tends to displace loop 9 of one unit would also tend to displace loop 11 in an opposite direction. But loop 11 can not move without imparting motion to loop 9 of the next unit. Thus the resilience of each unit is aided by those adjacent to it.

Fabric composed of the series of units above described can be easily manufactured and possesses maximum resiliency at all points while resisting any tendency to unduly sag in the middle portion thereof, all

parts of the fabric cooperating with all other parts in resisting an undue depression in any given portion of the mattress.

7 Referring to Fig. 3 it will be observed that it is possible to form the link with its longitudinal strand 5 and the end loops 6 and 7 thereof in the same manner as in Fig. 1, but with the portion 8 substantially straight and with the eye loop 9 reversed as compared with the loop 9 in Fig.

1, the arm 10 extending in the opposite direction substantially parallel to the portion 8 and crossing strand 5 on the same side and in substantially the same plane with the portion 8 The eye loop 11 is formed in the same manner as in Fig. 1. This modified construction does not provide the sling or hammock shown at 12 in Fig. 1 and the longitudinal lines of support therefore tend to yield more freely in bow form than is the case with the construction shown in Fig. 1, unless the fabric is inverted from the position in which the unit is illustrated.

If inverted, it is obvious that both portions 8 and 10 become supporting members for the portion 5 1 In either case, however, the connection of the cross strands or lines of support with the longitudinal ones is effective through the portions 8 and the eye loops '7 to resiliently support the strands and prevent them from separating.

I claim:

1. A wire fabric comprising a series of resilient integral units directly connected with each other along both longitudinal and transverse lines, each unit having a longitudinally extending shank formed of a single length of wire bent to form end eye tudinal and lateral extensions under strains exerted at the points of connection with adj acent units, the shank portion and one laterally extending arm being composed of a single strand, and the other laterally extending arm comprising an elongated loop, one side of which is a continuation of the laterally extending single strand arm, and the other side of which is in looped connection With the shank portion of the unit.

4. A wire fabric including longitudinally connected series of units, each unit comprising integrally a shank portion provided with connecting eyes at each end and a transverse portion crossing the shank and having an eye on each side of said shank, said eyes being adapted to engage with similar eyes in adjacent units.

5. A wire fabric including longitudinally connected series of units, each unit comprising integrally a shank portion provided with connecting eyes at each end and a transverse portion crossing the shank and having an eye on each side of said shank, said portions of each unit being relatively movable and resiliently secured against each relative movement.

6. A wire fabric comprising a longitudinally connected series of units having single strand shanks, and laterally projecting arms integrally connected with the shanks and interlocked with transversely adjacent units, the strand composing one arm constituting a continuation of the other across the shank, said arms being adapted for resilient flexion upon relative longitudinal movement of the units in adjacent series.
