SPRING ASSEMBLY FOR UPHOLS'I'ERY Filed Nov. 2, 1931 Patented Sept. 6, 1 932 roars A. stinxorr, or w ILME'rrE, :YIIKILINOIS SPRING ASSEMBLY Application filed November This invention relates to. improvements in spring assemblies for upholstery and has for its object to provide a simple,cheap, and elli cient'structure of this character which may be easily and cheaply incorporatedintoarticles of furniture, such. as chain frames,

couch or davenport' frames, and the likein suchgrouping' or association as the manufacturer of furniture may desire. I 7 10 More specifically stated, theinvention has for-its ob ect to provide-spring assemblies, each of which comprises a single strip of suitable material, such as sheet metal which is equipped with a row of fabric encased springs and equipped atvits ends with means for securing the strip toIa frame structure to provide the advantage to the. furniture manufacturer of enabling him to dispose the said strips in closely or widely spaced relation to each other, and also slightly angularly to each other to provide a composite spring as sembly of a shape best adapted to the shape of the frame elementto be equipped with the.

said spring assembly. r

A suital'i-le embodiment of the invention is illustrated in theaccompanying drawing, wherein: V

The structure of g V flat strip 1 of suitable sheet metal which may of a thickness and width to render. it only slightly flexible, or of a thinner and narrower stock having correspondingly greater flexibility. g

The strip 1 is provided atregular intervals, longitudinally thereof. and midway between "its side edges, with perforations '2. The

.numb'erof said perforations 2 will be equal to the number, plus one, of springs to be mounted the'reon, so that, if, six springs are to be so mounted,'there must be seven of said perforations 2.v V i The spacing of the perforations 2 from each other will be equal to the diameter of the springs :to be mounted thereon.

-A series of springs 3, of, equal diameter and encased in ,aseries of articulate fabric pockets or casings 4, is mounted on thestrip 1. Thesaid pockets or casings 4 are made of v a single strip of fabric folded upon itself and provided with parallel stitch-chains 5 extending transversely of the fold in the said strip, thus forming a series of flat pockets into which the springs 3 are inserted with their longitudinal axes disposed transversely to the flat walls of said pockets.

A stitch-chain 6 extending transversely to the stitch-chains 5 and disposed adjacent to and substantially parallel with the edges of thewalls of said flat pockets, serves to close the latter. The springs .3 are then turned in the pockets so that their longitudinal axes are parallelwith the stitch-chains 5. 1' The said pockets orv casings l are thus distended to cylindrical form and provide surplus material at the ends ofthe severalstitchchains 5 to form loosefabric projections 7; I The foregoing type of sprilig filled casings is well-known in this art.

The said fabric projections 7 along one set of substantially circular end walls of the pockets or casings 4 are passed through the perforations 2 ofthe strip land are secured againstretraction by means of a suitable resists of a wire 8 of. a length somewhat in eX- cess of. the/length of the articulate fabric v spring-filled structure, said wire being passed this invention includes a posite that upon which the spring-filled castaining device. The latter preferably con- I ings rest, and thus firmly secures the latter to v the strip The wire 8 is Preferably Provided atone end with a loop 9 formed thereon before the wire is inserted through'the projecting. portions 7 and the other end of the wire is then bent to form a loop 10, said loops 9 and 10 serving to prevent withdrawal of the wire 8 from the said projecting portions 7.

Obviously, the same or substantially the same result will be secured by passing an individual retaining element through each of said projections 7 as, for example, a conventional safety pin or a cotter-pin. v I The length of the strip 1 will be sufficiently greater than the length of the setor chain of spring-filled casings 4 mounted thereon as may be requisiteand necessary to enable the ends of said strip 1 to be secured-to opposed rails or portions of a furniture frame element, the opening in which is to be spanned by the said strip( 3.

These end portionsiof the strip 1 will be provided with perforations '11, as shown in Fig. 1, to receive nails, screws, or other securing means, or, as shown in Fig. 3, will be provided with loop formations 12 to receive wires or rods for associating a series of the strips 1 to form a spring assembly consisting of a number of said strips 1 with theirspringfilled casings 1.

: Obviously i of said strips 1 and its chain of ng-f' led cas igsd constitutes an ind sly. The great advantage of the i ention hes in the fact that lnumber of theseindividual ,iblies may be disposed side by side, closely or i 'ide spaced 110111 each other, to form a compo to s ring assembly of any fired areannd of a L feat vari ty of shapes 'th I f i of any .rurnitu're frame opencontain a spring assembly.

The supporting web may, obviously, be also provided of a width sufficient to receive two or more rows of spring-filled casings 4L,- without'departing from the invention.

I claim as myinvention:

1. A spring assembly comprising an articulate series of spring-filled fabric casings, a flat strip of sheet metal provided with a series of perforations spaced from each other a distance equal to the diameters of the springs in said'casings, the latter having loose fabric portions at the ends of the meeting points of the several casings and at the extremities of the ser a thereof projecting through said perforations in said strip, and substantially )Ir-ElilSflC retaining means extending through said loose fabric portions and spanning said perforations on the face of the said strip opposite that upon which said ca gsare supported.

2 is staring assembly comprising a supporting web of suitable material, fabric spring-filled casings disposed on one face of said web, saidcasings presenting loose fabric portions at diametricallyopposed points of their substantially circular ends and said web being pr vided withperforations through which said loose fabric portions project, and substantially inflexible fastening means theposed upon the other facevof'said web and passing through said loose fabric portions of said casings and spanning the perforations through which the said loose fabric portions project. 1 v

3. A spring assembly comprising a supporting web of suitable material, fabric spring-filled casings disposed on one face of said web, said casings presenting loose fabric portions at diametrically o'pposed points of their substantially circular ends and said web beingprovided with perforations through which saidloose fabric portions project, and means disposed on the other face of saidweb and passing successively through a plurality of the projecting portions of said loose fabric and spanning the perforations through which the said loosefabric portions 1 extend to secure the spring-filled casings to the web.
