tures, such as are employed in inner spring mat- 5 tresses, spring seats, spring beds, 4upholstered My invention `relates-to improvements in upholstery. It relates particularly to spring covering pads adapted for use onmetal spring strucfurniture andthe like.

One of the objects of my invention is to provide a novel spring covering pad ofthev kind described which is'particularly well vadapted for use on the top of coil spring structures, whiclris provided with novel means for preventing the struction as a unit.

- Afurther object of my invention is the provision of a novel spring covering pad of the kindV described, which is simple, cheap, strong and efficient.

The novel features of my invention are hereinafter fully described and claimed.- In the accompanying drawing which illustrates my invention, 2s Fig. l is a plan view, partly broken away, of

' my improved spring covering pad.` Y

Fig. 2 is a plan view, partly broken away, of a portion of one formof my improved sinuously formed spring strip' member for supporting `the padding sheet.

Fig. 3 is a section, enlarged. on the line 3--3 of Fig. 2.

Fig. 4 is a vertical sectional view, enlarged, of

A my improved spring covering pad shown mounted on coil springs and embodying the sinuous spring strip with; the binding strips shown in Figs. 2 and 3.

' Fig. 5 is a planview of the sinuously .formed spring strip shown attached by stitching to a" .4 0 portion of a sheet of fabric.

Fig. 6 is a reduced plan view of a modified` l designates an ordinary sheet of felted cotton ss padding, 2 a fabric sheet, such as burlap or To preventthe fabric; sheet 2 and the padding y sheet l being forced downwardly into or between s the coils 3, vmydnvention provides ya sheetlike layer,preferably disposedlbetween the sheets il and 2, and comprising a sinuously formed spring strip 4,- preferably spring wire. The sinuously: formed wire 4 is formed into a fiat layer of slightl0 lyless widthfth'an the width of the sheets i and 2, andi-its folds are heid spaced apart, in the form f shownfin Figs, 1, 2, 3 yand 4, by pairs of flexible gumxnedstrips [disposed respectively adjacent opposite edges of the layer. The gummedstrips 16 I, which may-'be of paper or other suitable material, are disposed at opposite sides I'of the wire "layer 4, and areimadeto adhere to eachother `and to the sinuous wire between thefolds of the latter Such binding together of the folds of the sheetlike wire layer, holds the folds from expanding apart, and enables the layer. to be formed into a roll, as designated by' 4, Fig. 8, from which it may be fed forwardly between padding `sheet I z5 and the burlap sheet 2, which sheets may also be fed rolls to superposed positions respectively above and below the sheetlike layer 4, lat whichl vpositions the three layers maybe simultaneously and 4.

The stitching I .is preferably extended transversely across and between the folds of the wire layer 4, as shown in Fig. 4, thereby firmly holding the wire layer 4 from shifting between the 36 sheets of padding and fabric.

By disposing the wire layer 4 above the fabric sheet 2, the wire layer is kept from contact with the upper ends ofthe coil springs 3 upon which rests the fabric sheet 2, thus eliminating scratch- 40 ing noises which might be made were the wire i layer 4 in contact with the coils l.

By providing the longsheets of padding, fabric and wire layer, disposingv them in rolls, and then feeding them from the rolls, and simultaneously withv the feeding operation, stitching the vsuperposed layers simultaneously together, a very economical and simple methodof manufacture of the spring covering pad is eiected, which enables a large output in a relatively `short time. By having thevrows of stitching I extending lengthwise of the three layers and'transversely. acrossA f thev wire sections and between thefolds of the sinuously formed strip 4 at intervals between the folds, the folds are held throughout from spreading apart, and the vstitching operation can4 be effected continuously simultaneously with continuous forward feeding of the three layers, thus effecting a saving of time and an increased emciency in the product.

As the assembled stitched together layers arev produced, they may be transversely severed to lengths suited for the particular purpose for which they are to be used.

In Fig- 6 andFig. 7 is shown a modified form of binding the folds of the sinuously formed wire vresilient material, as spring` steel or brass, and opposing stripsof each pair may be fastened to each other by welding, soldering, riveting or 2 otherwise.

As shownin Fig. 5, the sinuous strip l may be fastened alone to the fabric sheet 2 bystitching '8 extendingtransversely across and between thel folds ofthe strip adjacentto the `bendsl thereof.

The spring strip 4 having been sinuously formed and the folds thereof boundtogether, in the manner described, to form a.sheetlilren layer,k said layer -may be formed into a roll, asv @shown in Fig. 8, for convenience in handling and storing. The wire therefrom may then lbefedfrom the roll and interposed between padding and fabric respectively simultaneously'fed from'l rolls l and 2, and, while being so fed, the three Opposite portions of each strip In case it is desired layers may be simultaneously stitched together, as has been described, and as is shown in Figs. 1 and 4. The combined layers may then be transversely severed into sections of desired dimensions and of substantially even thickness throughout.

Such sections may then be disposed in suitablecasings, not shown.

Y I Y'Ijhe sinuous strip layer willhold the padding I -.from shifting and from entering between or into the springs 3. My improved spring covering pad, constructed as hereinbefore described, constitutes an integral structure, adapted for individual storage, shipment and for insertion into or removal from an upholstered spring construction of usual type as a unit, whereby manufacturers of suchspring constructions may obtain the unit and insert it therein, without requiring it to be built up piece by piece therein, thus affording economy in the manufacture;

Other modifications Aof my invention, within Hthe scope of the 'appended claim, may be made without departing from its spirit.

WhatI claim is:- In a spring covering pad, three layers, each layer having substantially even thickness throughout, comprising a fabric. sheet. a sheet of padding, and a sheetlike spring strip formed of sinuously bent wire between said sheets, and rows ofzstitching extending through the three layers transversely across and between the folds of said spring strip at intervals between the folds, whereby the folds V.are held from spreading apart throughout theirlengths `and the three layers are united together to form an-integral' structure, of even thickness throilghoutand, adapted for insertion or replacement as a unit.
