' E18 Claims.v (CL 5-2-30) The instant invention pertains to certainnovel features of structure andmode of operation in bed-springs and comparable cushions,incorporating a series of upright spiral springs, L

One feature of the invention resides in' anew or supplemental border-wire arrangement which is securely held in place without direct attachment to the erect spiral-springs with which itis associated. v

Another principle of the invention relates 'l30 a. so-called platform-top for the bed-spring or other cushion which is 'yieldingly secured to such auxiliary border or marginal wire referred to. i

To allow those versed in, and acquainted with, this art to understand and appreciate the favor-s ableand valuable, characteristics. of the present invention, a current embodiment thereof has been illustrated in detail in the accompanying drawing, and, for simplicity, like reference numerals have been employed in the severalviews of ,such drawing to designate or denote the same structural parts or mechanical elements a'nd from a comprehension of such construction other aims and objects ofthe invention will be perceived,

in this drawing- 7 i v v Figure 1 is a partial plan view of a bed-spring or springcushion incorporating the structural features based upon :the. new invention;

Figure 2 is an enlarged, fragmentary, plan view of a small portion only of the bed-spring or cushion; and

Figure 3 is an edge view or elevation of that fragment of the construction shown in plan in ure 2.

Referring to these views of the drawing, it will .be readily observed that the spring-cushion or bed-spring includes a number of suitably supported, upright spiral-springs H, II shown di- "agrammatically, arranged in longitudinal and transverse rows, the top convolution or turn of l each such spring having its end knotted, at l2 around the adjacent portion of the wire constituting the spring.

These springs may be of tapered or hour-glass former of any other appropriate conformation, but they are assumed to have the knots or their equivalents at the positions indicated, particularly with reference to the marginal springs.

As is clearly portrayed in Figure 1, the top or terminal rings of these springs are connected togetherin any approved fashion as by intersecting or crossing helical-springs l3, l3,

A continuous border-wire ll extends around the top margin of the structure, and, in the plane of the upper surface of the springs and such volution, as is clearly illustrated in Figure 3.

border-wire, in a manner well-known, has spacedapart, inner recesses or cavities receiving the outermost parts of the top convolutions or terminal 'rings of the marginal springs, such border- 3N wire at itscavities being deformed or clamped 5' at least in part inwardly around the end convolutions of the springs tohold them firmly in place, there being nothing new novel in that particular fastening means.

It istofbe noted, as shown in Figure, 1, that the stated knots or connections of all of the marginal springs are aligned along the sides and ends of its ends connected together in anyapproved or suitable manner at It], thus providing an endlessorfunbroken member which extends around the bed-spring beneath thetop rings or coils thereof and just outside of the knots I2 with whichthey may be incontactfor out of contact, but, in any: case, such supplementary border wire l5, at .each spring is wedged between its terminal-ring and the wire of the next lower conlhus such additive or subsidiary boundarywire I I5, so far as inward shifting or movement thereof is concerned, is fixed with relation to all of the marginal spiral-springs and through their top rings or coils is secured firmly to the main or principal border-wire Ill.

The platform-top for the bed-spring is composed of flat-narrow, longitudinal and transverse, metal bands or straps l6 and I1, respectively, located just above andbearing on the tops of the erect spiral-springs, with their points of, crossing in register with the axes of such springs.

The specified members l6 and I1 terminat 40 short of the inner border-wire l5 and their ends are connected to such element I5 by short helical-springs I8, I83, whereby the load strains impose-d on the superposed platform are transmit- I ted to the inner border-wire l5 and through the end-ringsof the spiral-springs to the outer border-wire l4.

The new and improved spring cushion or bedspring has its platform-top yieldingly joined to the multiple border-wires and by reason of the relation of the inner border-wire to the knotted portions of the spiral-springs, it cannot be pulled inwardly by the load on the platform and such inside border-wire is assisted in performing such v55 30 of the cushion being in substantial alignment for each side andeach end ofthe cushion, and a tions of the wires and just outside said connecof the cushion being insubstantial alignment for each side and each end of the'cushion, a main border-wire extended around the cushionsubfunction by its connection to the outer borderwire through the end-rings of the springs.

The bed-spring illustrated and described may have any type of support for the spiral-springs which seems to be desirable, but, in some cases at least, it is feasible to make the bottom and the topof the spring cushion alike or substantially' identical.

This invention is presented and defined in the appended claimswhich should be construed or interpreted as generically as permitted by the state of the prior art and yet preserve their validity, but, it is to be remembered that the in- 1 vention is not necessarily limited or restricted to the precise and exact structural details referred to because various changes and modifications may be resorted to without departure from the principles underlying the invention and without the loss or sacrifice of any material advantage incident to the employment of the in-" vention. r
