5 Claims. Y(Cl. `5351) `'This invention relates to new vand useful im'- provements in a spring mattress structure, and has particular reference to a spring mattress structure providing a support ior padding or upholstery to be carried by said mattress, whereby said padding or upholstery is prevented from working into the spaces within and between the component springs.

The principal object of the present invention is the provision, in a spring mattress having a plurality of helical springs arranged in rows with the adjacent portions of their top and bottom end coils joined by a plurality of helical binder coils extending in substantially parallel relation across the surfacer of said mattress, of a pad ding support comprising a plurality of parallel support wires extending transversely to said binder coils, said supporting wires being positioned entirely on one side of the wires forming said binder coils and between adjacent loops of said coils, and a retaining wire positioned axially in each of said binder coils, whereby said sup,- porting wires are retained between the loopsof the binder coils.

Other objects are simplicity and economy of construction, ease oi" assembly, and adaptability of the padding support to'be, applied to previously fabricated spring mattresses.

With these objects in view, as well as other objects which will appear in the course of the specication, reference will be had to the' drawing, wherein- Fig. l is a plan view of a spring mattress structure embodying the present invention.

Fig. 2 is a sectional View taken on line II--II Y of Fig. l.

Fig. 3 is an enlargedfragmentary section taken on line IIL-III of Fig. l.

Like reference numerals apply to similar parts throughout the several views, and the numeral 2 applies to each of a plurality of helical springs,

saidsprings being axially parallel-l and arrangedV v in a plurality Yof parallel rowsv as shown in Fig. 1 to form a mattress. Any number of springs may, o course, be used, depending on the size of the mattress or cushion to be built. The top loops and the bottom loops t of said springs each lie substantially in a horizontal plane. The top and bottom marginal edges of the mattress thus formed are bound by helical binder coils of relatively small diameter, coils 8 being coiled about the outer portions of the top and bottom FIO springs 2 in each of the outer spring rows. These end loops of adjacent'springs 2 in each row overlap slightly, and are joined by binder coils I2, which' are coiled about said overlapping portions Vof the spring loops. Coils l2 are parallel to coils 8, andy extend `substantially across the mattress between corresponding springs of each row. Each of coils 8, Ill and I2 is securely anchored in place by having its end portion wrapped tightly about an adjacent loop of one tending in parallel, spaced apart relation across` the top 'of the mattress. Said wires are parallel to binder coils Ill and transverse to coils I2, and are secured in place by twisting the end portions of each wire around'a convenient loop or the adjacent coil 8, as atv I6. Each of supporting wires I4 passes beneath the wires from which coils I2 are formed, but is rpositioned between adjacent pairs of loops of each or said coils, as best shown in Fig. 3. I

Thus, each wire I4 is substantially secured against lateral movement at each point it intersects a coil I2, except that were wires l2v not further supported they could be pushed downwardly from coils I2 V,and become displaced. This is overcome by inserting a retaining wire I8 axially ythrough each of coils I2, said wire passing be-` heath each of Ywires lli. The ends of wires I8 are twisted around the end loops of coils I2 as at 20. Each of wires i4 is thus supported rmly at each of coils l2, since it passes through a substantially closed loop formed by said coil and its associated retaining wire I8;

jlt'is apparentl that a simple, efficient padding support has `been produced whichmayybe. at-

tached easilyv to any spring mattress structure such as is used in bed mattresses, furniture cushions, automobile upholstery, andv theA like, and while it is inseparable from and forms a structural part of the mattress, it may be attached to a'mattress previously fabricated. The spacing of support wires I4 may be regulated to provide adequate support for padding or upholstery, and said wires also provide convenient means for-attaching said upholstery. Wires I4 end loops of springs 2 at each end of the spring rows, and coils Ill being coiled about the outerV portions of the top and bottom end loops of and i8, since they extend across the mattress at right angles, and since they are anchored at each end, also` serve to reinforce the mattress structurally against horizontal distortion.

It is apparent that many minor changes of design and construction could be made without departing from the spirit of the invention, and it is therefore desired to be limited only by the cope of the appended claims.

What I claim is:

1. In a spring mattress of the character described having a plurality of helical springs bound together by marginal binding members and a plurality of substantially parallel intermediate binding members extending between and joining adjacent rows of springs, a padding support comprising a plurality of parallel elongated support members extending across said mattress transversely to said intermediate binding members, and members extending across said mattress transversely to said support members and operable in conjunction with said intermediate binding members to retain each oi said support members against any material lateral movement at its point of intersection with each of said intermediate binding members.

2. .The combination, with a spring mattress structure comprising a plurality of helical springs arranged in parallel rows, helical binder coils which coil about the outer portions of the top Y and bottom loops of the marginal spring, and

intermediate helical binder coils extending in parallel relation between adjacent rows of springs and coiled about the adjacent portions of the top and bottom loops of the springs in said adjacent rows, of a padding support comprising a plurality of substantially parallel support wires extending across the top of said mattress transversely to said intermediate binder coils, each of said support wires being disposed on the same side of all of said intermediate binder coils and passing between adjacent loops of each binder coil, and a retaining Wire positioned axially in each of said intermediate binder coils, whereby said support wires are retained between the loops of said coils.

3. The combination, with a spring mattress structure comprising a plurality of helical springs arranged in parallel rows, helical binder coils which coil about the outer portions of the top and bottom loops of the marginal spring, and intermediate helical binder coils extending in parallel relation between adjacent rows of springs and coiled about the adjacent portions of the top and bottom loops of the springs in said adjacent rows, of a padding support comprising a plurality of substantially parallel support wires extending across the top of said mattress transversely to said intermediate binder coils and secured at their ends to said marginal bindercoils, each o f said support wires passing beneath the wires forming said intermediate binder coils but positioned between adjacent loops of said coils, anda retaining wire positioned axially in each of said intermediate binder coils and secured at its ends tothe end loops of said coils, said retaining wire passing beneath each of said support wires, thereby retaining said support Wires between the loops of said binder coils.

4:. A spring mattress structure comprising a plurality of axially parallel helical springs arranged in parallel rows, binding means extending around the upper and lower marginal edges of the mattress thus formed and connecting said springs, intermediate binding members at the top and bottom of said mattress extending transversely to said spring rows and connecting the corresponding adjacent springs of each of said rows, elongated supporting members extending in parallel relation across the upper surface of said mattress transversely to said intermediate binding members, means for securing said supporting members against longitudinal movement, and elongated retaining members extending across Ythe mattress transversely to said supporting members, each ofsaid retaining members operating in conjunction with one of said intermediate binding members to secure each o f said supporting members against material lateral movement at its point of intersection with said binding membe 5. A spring mattress structure comprising a plurality'of vertically parallel heli-cal springs a1'- ranged in parallel horizontal rows to form a mattress, helical binder coils extending along the 'upper and lower marginal edges of said. mattress and coiled about the outer portions 0f the top and bottom end loops of said springs, intermediate binder coils extending across the upper and lower surfaces of said mattress transversely t0 said spring rows and each coiled around the adja cent portions of the top and bottom end loops of corresponding adjacent springs in each of said rows, parallel supporting wires extending across the top of said mattress transversely to said intermediate coils, each of said supporting wires being disposed beneath the Wires forming said intermediate binder coils but passing between adjacent loops cf each of said coils, means securing said supporting wires against. longitudinal movement, Va retaining wire positioned longitudinally within each of said intermediate binder coils and passingV beneath the supporting wires intersecting said coil, and means securing said retaining wires against longitudinal movement.
