U PHOLSTERY-SPRING CONSTRUCTION.

To all whom it may concern."

Be 1t known that I, LEONARD A. Youne, a

citizen of the lUnitedv States, and resident of Highland Park, Wayne county, State of Michigan, have invented certain new and useful Improvements in Upholstery-Spring Constructions, of which the following is a specification.

In the application of upholstery over the tops of upright body springs, common in seats and the like, it is-advisable to so carry the upholstery over spaces where no dlrect support is afiorded it, that it does not tend to bunch or mat or sag, but preserves its spring constructions and more especially to initial condition and position.

This 1nvent1on relates to upholstery a mat for carrying the upholstery on the body springs-or like supporting means in such a way that local depressions are obviated while at the same time the supporting means is elastic in all directions and is capable of yielding generally with the rest of the spring structure when under load and shocln- The invention consists in matters hereinafter set forth, and more particularly p0inted out inthe appended claims. 1

In the drawings: 1

Figure l is a view, partially in longitue dinal section and partially in elevation, of a portion of an upholstery construction that embodies features of the invention;

Fig. 2 is a view in detail of a portion of a supporting mat;

Fig. 3 is a view in detail showing slight modifications in the disposition of the elements of the mat; and i Fig; 4 is a view in detail largely diagrammatic, showing further modifications in the arrangement and disposition'of the mat parts. i

In the drawings, which are largely, diagrammatic, a supporting frame 1 of any preferred and suitable construction, carries upright bodyf springs 2 of hour-glass or other desired type.

A sheet 3 of flexible fabric may be placed upon the body springs 2 and the latter may carry a rim frame 4 also suitably clipped or otherwise secured thereto in any well' knownv manner. The sheet 3 is herein shown diagrammatically'as if. it is perfectly straight although ofcourse it is not taut Specification of Letters Patent.

enoughforthis, but conforms to slight irregularities in the carrying members.

A sprlng mat lies upon the body springs and the interposed sheet 3, if the latter is used. The mat is made up of strips 5 cons stlng each of a wire or like thin spring ribbon, bent transversely into crimps or flutes, all in substantially the same plane whereby each strip is longitudinally elastic and whereby each flute is likewise capable of local movement in and out of its plane in relation to the rest of the strip. Strands 6 connect the fluted strips, each strand being a wire spiral such as is commonly used in the ordinary woven wire fabric, the convolutions of the strands encircling portions being engaged by the convolutions of the.

strands. The usual upholstery, indicated generally at 10, is placed upon the mat and the cover 11 thereof may be brought down and secured in any convenient manner to the base frame, as for example, by insertion in v Patented Feb. 3, 1920. Application filed February 10, 1919. serial No, 276,227.

member of the base frame I.

As a result of this construction, the up- ,holstery is afi'orded k perfect .1 support throughout its entire area by a mat which bridges intervals between the main body springs and prevents local depression in the upholstery while at the same time the elasticity thereof, both longitudinally and lateral, allows the mat to conform generally to any deformation of the construction as awhole when under load.

' Obviously, changes in the details of the construction may be made without departing from the spirit of the invention and I do not care to limit myself to any particular form or. arrangement of parts.

' I claim: n 1. In an upholstery spring construction, a mat for reinforcing and supportingthe tially upholsteryon thebody springs comprising a plural1ty of longitudinally elastic fiat bands of crimped and fluted wire secured in spaced relation and connected by transversely disposed spiral wires.

2. In an upholstery spring construction a mat comprising strips formed of wire having flat flutes and connected in substanarallel spaced relation by spiral wire, t e convolutions of' which enclrcle w portions of the flutes of adjacent strips.

3. In an upholstery spring construction, a body of upright coiled sprmgs, a sheet of flexible fabric on the springs, a mat on the sheet formed of fluted wire strips held together in spaced relation by wire spirals woven around corresponding portions of adjacent strips, and upholstery superposed transverse relationto the wire strips, upi -holstery filling resting on the mat and an upholster cover on the filling inclosing the sides of t e structure. i

5. In an upholstery spring construction, a base frame, u right body s rings mounted thereon, a s eet of flexib e fabric, running on the body springs, a mat resting on the sheet formed of a set of longitudinally expansible metal members extending from end to end thereof and interwoven with and held in spaced relation by longitudinally expansible spiral metal members extending from side to side of the mat, and

upholstery resting on the mat.

6. In an upholstery s ring construction for supporting the upho stery on the body springs com rising a set of flat strips formed of wire bent into flutes transverse to the strip, each band being lon itudinally elastic an transverse wire spiras through which corresponding flutes of wire strips are threaded and held in spaced relation, the mat being longitudinally and laterally LEONARD A.
