UNITED STATES PATENT ()FFICE.

SAMUEL BRONSTIEN, OF ST. PAUL, MINNESOTA.

WIRE FABRIC.

To all whom it may concern Be it known that I, SAMUEL BRonsrmN, a citizen of the United States, residlng at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Wire Fabrics, of which the following is a specification, reference being had to the accompanying drawings.

T his invention relates to certam improvements in wire fabrics and has relation more particularly to that class of fabrics employed for bottoms of beds, couches and the like; and an object of the invention 1s to provide a device of this general character of a novel and improved construction and wherein are employed a plurality of wire units or links of duplicate fo rmation.

It is also an object of the invention to provide a bedfabric of this general character of a novel and improved arrangement possessing pronounced flexibility and so arranged that the weight imposed upon a part thereof does not affect the remainderof the fabric.

Furthermore, it is an object of the invention to provide a fabric of this general character of a novel and improved arrangement which is substantially noiseless.

The invention also consists in the details of construction and in the combination and arrangement of the several parts of my improved wire fabric whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claim.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a fragmentary view in top plan of a fabric constructed in accordance with an embodiment of my invention, and shown in applied position; Fig. 2 is an enlarged sectional view taken substantially on the line 22 of Fig. 1; Fig. 3 is an enlarged sectional view taken substantially on the line 83 of Fig. 1; Fig. 4 is a fragmentary view in perspective, illustrating the interlocking engagement between adjacent strands as herein embodied; and Fig. 5 is a Specification of Letters Patent.

Application filed January 31, 1914.

Patented June 23, 1914. Serial No. 815,775.

view similar to Fig. 4 but illustrating a different interlocking engagement between adjacent units.

As disclosed in the accompanying drawings, 1 denotes one of the longitudinal side bars of a bed frame and 2 and 3 the upper and lower end or cross bars, respectively, which bars, as herein disclosed, are conveniently and cheaply formed of angle bars and adapted to be suitably connected one to the other in a conventional way. The cross bars 2 and 3 have their upstanding flanges apertured, as at 4: for the reception of the anchoring members 5 and 6 for the fabric proper, the members 5 being shown as hooks while the members 6 are disclosed as helical springs to afford resiliency and elasticity, as is believed to be obvious to those skilled in the art to which my present inventionappertains.

Referring now to the fabric itself, in which the novel features of the present invention more particularly reside, this fabric is made up of a series of parallel longitudinal strands each formed of duplicate or substantially duplicate bent Wire units connected end to end, which units or links are provided intermediate their length with integral lateral extensions adapted to be interhooked midway of a link or unit in an adjacent strand to connect the latter as well as form spaced filling elements for the sup port of the superimposed mattress.

Each of the units, as herein disclosed, is formed from a single length of wire of suitable gage, according to the load to be sustained, which wire has its extremities bent inwardly to afford a pair of closely adjacent parallel longitudinal limbs 7, the overlapping portions of such inwardly directed extremities being laterally directed and interwoven, as at 8, with the freeends thereof spaced apart and formed into the rearwardly directed hooks 9-9 adapted to engage a limb 7 of an adjacent strand.

The adjacent extremities of the links or units of each strand are adapted to be interlocked and, as herein disclosed, I accomplish this purpose by having one extremity of the unit or link enlarged, as at 10, to afford an eye while the opposite extremity of such unit or link is bent downwardly and rearwardly to afford a hook member 11 adapted to pass through the eye 10 of the adjacent unit or link. This arrangement I employ in all the links or units except those units which are adapted to be engaged with the spring member 6 wherein the coacting eX- tremities, as at 14, are straight. While I have specified these latter units as adapted to be engaged with the anchoring members 6, it is to be observed that the arrangement of the strands could be reversed and they could be caused to engage with equal facility the members 5, herein disclosed as hooks.

From the foregoing, it will be observed that all of the links are substantially of duplicate construction except the units comprising one of the longitudinal edges of the fabric and wherein such units or links are not provided with the laterally directed hook members, as is believed to be self-evident.

By having the links or units directed as set forth and by having such links or units of one strand engage adjacent strands, as has hereinbefore been described, it will be readily perceived that the parallel limbs 7--7 permit such individual flexibility or elasticity that when weight is put upon any part of the fabric, it does not in any way affect the remainder of the fabric. This I have conclusively demonstrated in actual practice. I have also found that by having units or links constructed as herein set forth and assembled as disclosed, the fabric is substantially noiseless, which is a feature much to be desired.

As illustrated in Fig. 5, the parts are identical as has been described relative to the remaining figures but it is to be observed that in interlocking the adjacentunits, the hooks 9 are disposed across both of the limbs 7 and positioned to either side of the portion 8 whereby it will be observed that the engagement of the hooks 9 is with the outer limb 7 in lieu of the inner limb, as disclosed in Fig. 4.

From the foregoing description, it is thought to be obvious that a wire fabric constructed in accordance with an embodiment of my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and by reason of the effectiveness with which it performs its requisite functions; and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

A unit for wire fabric, formed from a single strand of material and comprising a pair of parallel longitudinal limbs, the ends of the unit being provided with an eye and a hook respectively for inter-engagement with similar units, the extremities of the strand being connected at substantially the longitudinal center of one of the limbs, such connected portion being laterally disposed with the ends thereof separated and disposed in substantial parallelism and terminating in hooks for engagement with a limb of the parallel adjacent unit.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

SAMUEL BBONSTIEN.
