Another object is to provide an improved nonsag Yupholstery construction of the above nature which will be relatively inexpensive to manufacture, simple in construction, compact, ornamental in appearance, and very'eflicient and durable in use; Y

With these and other objects" 'in view, which will appear as the description proceeds, there have been illustratedin the accompanying drawing two forms in which the invention maybe conveniently embodied in practice. A

Figure 9 is an enlarged transverse sectional view on the line 9 9 of Figure '7, taken through one of the indented sections.

Referring now to the drawing wherein like reference numerals `designate like parts throughout the several view, the numeral I0 denotes an open on the line 2-2 of Fig* j rectangular wooden seat irameof' an article of upholstered furniture, such asf a chair, supported on four legs or feet II'. A` plurality of coiled cushion springs i2, preferably` conical in form, are secured at their upper. ends in'theusual manner, bymeans not shown, to the upholstery seat covering I3, and said springs are preferably arranged in alined rows within theirame. IE) to properly support the upholstery covering I3. The springs I2 are in `turn supported by two rows of crossed parallel metalstrips I4 vand Ida, secured at their endsto said frame I0.

The strips I @may be made of any ,suitable strong metal having sufli'cient tensile strength, to

preventsaid strips from stretching during use. The rst form of stretchable metallic strip IA shown in Figures 1 to 6; isprovided with a series of cooperating upstanding loops I5, and depressed loops I6 and I 1 arrangedin groups which areuniformly spaced apart the entirer length of said strip. The loop I 5 ofeach ,group is struck upwardly from the center of the strip I4 while the loops IS and I'lV are struck downwardly from the strip I4, one on either side of the loop I5. Intermediate each group of loops I5, I6, and` I1, `the strip I4 is provided with a round hole I8 which serves to locate fastening members, such as screws or nails I9, whereby the strip I4 may be securely attached to the frame Il). In the modified form of strip 20, shown in Figures 7 to 9 inclusive, indicating, raised, indented pointsv 2l, are substituted for the holes I 8 of the firstprm for receiving the fastening members I 9, which may be drivensthrough said sections 2l.` to attach said strip to the frame I0. The indented points 2I are raised upwardly fromthe surface of the metal strip and are adapted to be easily punctured by the attaching nail or, screw when the latter is driven through it by the blowsof a hammer. The raised4 indented points also serve as indicating means to insure the placing of the strip with its bottom surface againstihe furniture frame. "The strips I4a are made plainv and` unstretchable, hav-` ing no raised or depressed loops,` but are pro-k vided merely with spaced apertures I8 or indentations 2| for the attaching nails or screws I 9.

Operation In operation, one end of each stretchable strip strip I4 (or 20) will first be nailed, screwed, or otherwise permanently attached to the front frame member 22, as shown at the left in Figure 2, leaving the opposite ends of said strips I4 loose. The crossing plain strips Ida will then be inserted in the position shown in Figure 1, leaving both then be stretched and flattened by a special pull-" ing tool, not shown. The unoccupied loops I5, I6, and I1, will thus be forced back into flat alignment with the remainder of the strip Hand the coll-lled loops will frictionally'engage opposite sides of the coil 23 embraced thereby. The flat f remaining portion of said strip I4 will of course not be stretched. The free ends of the stretchable strips I 4 will next be securely fastened to the rear frame member 24 by screw or nails I3 driven through the holes I8, orthrough the indented points v2|, as the case may be.y Theplaincross strips Ida will finally be nailed at both ends, with-` out stretching to theside frame members 2G and 2,1. jAs shownin Figure 1, the strips I4 preferably fcross" eachV other'at right angles to the center axis 25 of each ,spring I2, andthe bottom convolution 23 ,-o'f each spring `willbe supported uponv said crossed strips atfour points, thus providing four pointjcontacts therefor. I y t One advantage ofthe present invention is, that the operationof stretching the groups of coilembracing `loops of each stretchablev strip I4 will cause said loops Yto bind tightly upon `the lower convolution of L the coil jsprings, thus effectively lo'clingjthem from shifting out of position. The stretchingjprocess also, straightens the-unused loops I5, I5, and I1, so that there ,will .be no pos- 'sibilityY or .further stretching ofth'e' strips Ill or 2li) during use `by Y the weight of persons using. the articlepf v furniture. A further advantage, is that norattling can occur at the attachment points, because all ,looseness between the spring coils-.23 and the strips ,Ill (or 20), has been eliminated. i ',jltwill beunderstood that it is within the scope ofthe present inventiontoiemploy the `construction-herein disclosed on mattresses, box springs, bed springs, etc., in which casethe crossed metal strips will be located onr both the top and bottom surfaces thereof, above and below the coil springs llocated therein.

It lwill Ialso beunderstood that if desired, the plain ,cross strips Iller, disclosed` herein, may be omittedandreplaced by strips of webbing-within the spirit ofthe invention. f l kWhile there `have., been disclosed in this speciicationtwo forms inwhich the invention may be embodiedinpractice, it is to be understood coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent, is:

l. The process of manufacturing an upholstery construction which comprises: securing to an open frame of an article of furniture a pair of crossed narrow metallic strips, one of which has a plurality of groups of stretchable upstanding and depressed loop sections, inserting the .lowermost convolution of a coil spring within a pair of said groups of loop sections for supporting said spring upon said strips, and frictionally locking said spring to said strips by permanently stretching said strip having the loop sections beyond the elastic limit of the metal thereof to cause said loops to flatten and tightly embrace n the lowermost convolution of said spring.

that these forms are shown for theI purposeyof.

illustration only, and that the invention is not to be limited to the specific disclosures, but mayV be embodied in various other forms withoutde-v.

parting from its spirit. In short, the-invention includes all theY modifications and-embodiments 2. The process as defined in claim l in which some of said groups of loop sections `are unoccupied by coil spring convolutions, andin which the step of stretching said strip causes said unoccupied loop sections to iiatten out and prevent any possibility of further stretching of said strips during use. v v j 3. Theprocess of manufacturing an upholstery construction which comprises: placing upon an open frame of anarticle of furniture a pair of crossed metallic strips, one of which has a plurality of groups of stretchableupstanding and depressed loop sections, and both of which have a plurality of attaching apertures, inserting the lowermost convolution of a coil spring within pair of said groups of loop sections for supporting opposite sides of said spring, frictionally locking said spring in position by permanently stretching the strip having said loop sections to cause said loops to flatten and tightly and frictionally embrace the lowermost convolution of said spring, and finally securing said crossed strips to said open frame byvdriving attaching means through the apertures of Vsaid strips in alinement with the edges of said frame. 4. The process of manufacturing an upholstery construction which comprises: placing iupon an open frame of an article of furniture a pair of crossed metallic strips, one of which has a plurality of groups of stretchable upstanding and depressed'loop sections, and both of which have a plurality of attaching sections, inserting the lowermost convolution'of a coil spring within a pair of said groups of loop sections for supporting said spring, frictionally locking said spring in position by permanently stretching the strip having said loop sections to cause said loops to atten and tightly and frictionally embrace opposite sides of the lowermost convolution of said spring, and nally securing said crossed strips to said open frame by driving attaching means through the sections of said strips in alineinent with the edges of said frame. f y RUTLEDGE A.
