v This inventionrelates to a spring structure andmethod of producing the same, and [more particularly to such a structure which isparticularly adapted for use in furniture 5 and automobile upholstery, mattresses, cushions and the like, and in whichhelical springs are employed each of which is housed within an independent separate cloth "pocket or housing andanumber of springs andtheir" 1o housings are arranged'side by side to form a grou the upholstery. v

One of theprincipalobjects is to provide anindepen'dent individual housing for each 5 of the helical springs by means of which the springs and their ousings may readily bearranged to form a springstructure'of "any desired configuration; Thus if it is necessary to leave a void, inthe structure to accommo-' 20 date an arm or other part of the furniture frame the individually housed springs can be left outiin this place. 7 By thisjmeans the assemblyof spring structures in odd shapes is greatly facilitated.

'A'furtheri'objectisto substitute for the burlap 'backings generally employed} in housed sprin structures, a plurality of cords 1 which extenacross the spring structure and diametrically across the ends of the indi- .i Q vidual spring housings and tie the corresponding edges of the housings together. -j Such a method of tying the structure 150'? gether has been found to be markedly superior to the usual bu'rlapbacking in point 0 135 wear "and in "addition ermits individual housings to be cut away f rom therest of'the' I group without alteration of the rest, when a I completed structure isbeing fitted to an iri regular shaped pieceof furniture or the like. Furthermore, tying of the springs by means g I vention is composed ofa group of upholstery 0f cords inc'ontradistinctiontosewing them of the'burlapeand also greatly facilitates the operation of assembling a springstructure'by }.Individua11y&housed springs use lend themselves more readily to use on rounded surfacessuchas the curve of the upholstered] arms'of a lounge since theycan'be re'adlly 1 tied to conform to the curvature thereof. I

of springs which yieldingly support I V ual, independent housing in which the end coils of the spring bear against a double thickness of material thereby in its condition.

A still further aim is to provide such a housing which can be quickly, readily; and accurately 'sewedwith an expenditure of a t minimum amount of time, labor and material, thereby permittingof producing the structure at low cost.

o-FFIC Another purpose is to provide such a hous-;

manner shown in Figs. 4-7, this operation being as follows:

A strip of cloth 11 is marked into lengths as indicated at 12 and between these marks is provided with gage marks 13 which divide the strip into three parts, a bottom part. 11, ashort end 11", and a long end 11. A second strip of cloth 14, of the-same length as the lengths of the strip 11 is then folded over to form a loop and its opposite ends are brought together and placed along one edge of the strip 11, the loop extending transversely across the strip 11, as best indicated in'Fig. 4. The strips are then runthrough a sewing machine and the ends of the strip 14 are sewed to the edge of the strip llby stitches 15. In production, the sewing is continued along the edge of the strip 11 and the operator of the 'sewingmachine places the strips 14 in proper relation before the needle passes over the marked part 11. The strip 11 is then cut into lengths along the marks 12.

The strip 14has previously been marked as indicated at 16 so as to demarcate two side parts 14 and 14 and an upper central part 14j,at oneside of which the strip is folded. The loop formed by the strip 14 is now opened up, as indicated in Fig. so that a bottom part 14 lies on the bottom part of 11 of the strip 11, the sides 14 and 14 rise from theledges of the strip 11 and the upper part 14 is arranged horizontally.

The short end 11 of the strip 11 is then brought u and its end arranged under the correspon ing edge of the upper part 14 as shown in Fig. 6. Thereafter-the long leg .11 is brought u and over the upper part 14 and its end p aced in alinement with the opposite ed e of the upper part 14 of the str1p14. T epocket is then sewed,the stitchcs 17 passing-throughthe endsof the strip 11 and the edge of the upper part 14 of the othenstrip. a

The upholstery spring 18 is then com- ,rprwsed and passed through one of the four openings at the corners of the pocket. The spning is then placed in proper position and released, the ends of the spring bearing ,against'the upper and lower parts 14 and .14 ofthe pocket which are reinforced by the upper and lower parts 11 and 11 which overlay and are secured tothese parts. By

thisimeansitwill be noted that by two sewing operations anindividual pocket is provided 1' zwhwh has reinforced ends and full flexibility atits sides. Moreover, the-operation of making the pocketis extremely simple and can'be .done rapidly and efiiciently by, one not perticularly fikilled at such work.

In-using the springs inupholstered furniturmunattresses or the like, theseveral springs areitled together and placed in the center of itheamattress oronithe supporting frame of the furniture. in t8 isillustratedaacon- *i-riweMidM1'form1of ichair back composed of a they are inalinement in bot cord or strmg 26 1s passed through the outer pockets and the spring therein.

wooden frame 19, back webbing 20 supporting main back springs 21, and burlap coverings 22 and 23 over the webbing and the springs.

The spring structure forming the subject matter of the present invention is adapted to impartgreatcr softness and is placed over the burlap cover 23, the upper end of the spring structure bein curved over the upper side of the chair frame. The usual stufling 24 is then placed over the spring structure and the whole covered by the usual cover 25.

To form the spring structure, the several individual, independent spring pockets are grouped together as shown in Fig. 1 so that directions. A

The cord 26 is then tied at this point as best shown in Fig. 3 and is passed diametrically over the pocket and is passed through the corners of the adjacent pockets, around the corresponding end coils of the springs thereon and tied, thereby securely tying the two Ina similar manner, a complete row of spring pockets are tied together, the row being tiedat its opposite or under side in the same manner by cords 26. together in the same mannerby cords 27 and 27 which are arranged at right angles to the first cords and tie the spring pockets intransverse-rows.

. :If a springstructure of irregular outline is desired, it is apparentthat any number of the spring pockets 10 maybe left out to make the structure conform to the desired shape.

Thus, as shown in Fig. 1,if it is desired to have the structure fit about a projecting arm or the like,-.the spring pockets'may be left out to'form an indentedcorner or side. If also, in making furniture in which the cover is buttoned down atspaced intervalsto form a pillowed surface instead of the usual smooth upholstered surface, one of the spring pockets 10 at the center of 'the structure can readily be left out and the cover drawn into the voidleft thereby. Such a construction is indicated in Fig.8 in which one of the spring pockets 10has been left out at the center of the structurcfand the cover drawn into the void left thereby and secured to the burlap backing :23 bymeans of abutton 28.

It is apparent that such irregularities may .be provided for either by leaving the spring pocketout in the course of manufacture, or the same may be cut. out after the spring structure isassembled; In the latter case the spring pocketor pockets to be removed are out free without disturbing the rest of the structure.

If-itiis desired to have the structure curve, as aindicatediin FigQS' in which the structure curvesiaroundthelback ofthe ch air, one set of 1 The several rows are-then tiedcords is tied so as to leave a length of cord 29 between the rows of pockets at the place where the structure curves, the cord being quires relatively unskilled labor to produce the same.
