2 Claims.
This invention relates to improvements in spring liner assemblies.
An object is to provide an improved spring liner assembly which is so constructed as to prevent the wadding or cotton batting from being forced downwardly into the spaces between a coil spring assembly which supports the entire upholstery of a spring cushion such as the seat or back cushion of a motor vehicle; which spring liner assembly is of simple construction, inexpensive to fabricate and consists of a minimum amount of material.
Heretofore spring liners have been provided wherein a plurality of reinforcing stiffening members which were generally short sections of spring wire were held in spaced apart substantially parallel relationship in a row by a sheet of fabric to which the sections were secured as illustrated in applicants issued Patent No. 2,423,- 159, July 1, 1947. Such spring liner was interposed underneath the wadding and upholstery' material and overlying the spring assembly as shown in said patent.
The present invention consists in a provision of a spring liner adapted to serve the purposes of the conventional spring liners of commerce and which employs a minimum amount of material and is inexpensive as to cost.
Another object is to provide a spring liner of the character above described which is adapted to be secured to and form a part of an overlying layer of cushion forming material for application therewith to the spring assembly in the building up of the spring cushion.
Other objects, advantages and meritorious features of my invention will more fully appear from the following description, claims and accompany ing drawings wherein;

Fig. 10 is a perspective of a fragment of the liner shown in Fig. 6. Y
Spring liners of the character herein described are generally used in spring cushion assemblies being interposed between the wire spring assembly and the overlying layers of cushion forming material. These overlying layers of cushion forming material include a layer of wadding or cotton batting. The liner is provided to prevent this wadding from being pushed into the spaces between the coil springs. In the assembly shown in Fig. 1 there is a wire spring assembly which is made up of a plurality of conventional coil springs 20 which are here shown as of the hourglass type. These springs are mounted within and between upper and lower boundary frame wires 22 and 24. They are secured to the boundary wires and to each other by wire clips commonly referred to in the industry as hog rings 26. Certain of these coil springs 20 may be enclosed within fabric pockets 28.
This complete spring assembly is overlaid with layers of cushion forming material. A conventional arrangement is shown in Fig. 1, conventional except for my improved liner, wherein there is an overlying layer of upholstery fabric or covering material 30. Underneath this outer layer of upholstery fabric, there is a layer ci wadding or cotton batting 32. A layer of fabric 34 such as a netting may be spread over the layer of wadding underneath the upholstery fabric. The wadding may itself be secured to or overlay another layer of fabric such as burlap indicated as 36. These different layers of material are stretched over the wire spring assembly and down over the sides and ends thereof and secured to tbe underside of the spring assembly in any suitable conventional manner.
My improved spring liner is shown as interposed between the several layers of upholstery material and the wire spring assembly.- This spring liner consists yof a plurality of reinforcing stiffening members 38 placed in a row in substantially parallel spaced apart relationship as shown in the drawings. This row of members is held together in such spaced relationship and is carried by a pair of flexible longitudinal strips 40 which extend along te ends of the members 38 and to which these members are secured.
These members 38 may be formed of short lengths of spring wire. The strips 40 may be formed of burlap or other suitable flexible material. In Figs 1 through 5 of the drawing each burlap strip 40 is shown as folded over along one margin as at 42 providing a marginal fold about which the ends of the wires 38 are bent as at 44 as shown in the drawing. This spring liner is adapted fto'besecured .to the under-surface of the burlap .sheet 36 by a suitable adhesive. In Fig. 5 the upper surface of the strip 40 is shown as coated with adhesive such as latex 46. Both strips 40 are so coated. These coated surfaces of the strips 40 are secured to the under surface 'of the burlap sheet 36 and cured @thereon :so 'as to form secure adhesion.
If desired, the spring liner may be secured 1drectly in a similar manner to the underside of the layer of wadding 32 without the interposition Aof the bui-lap sheet 35. When so secured Vto lan overlying layer of cushion forming material, whether the wadding layer :32 or the .burlap la-yer f36,.these cushion .forming layers may then be placed over the wire spring .assembly as shown.
vDue tothe fact that the reinforcing stiiening members 38 are interposed between thestrip 40 and .theloverlying layer of cushion forming vmaterial such as the burlap sheet n36, the members 38 .are .held to the burlap sheet in .spaced apart parallel relationship. In Eig. 4 each strip dll is shown as `folded to provide a :fold 48 which `extends -parallel to the yfold ll-Z and the opposite .margin of the strip and projects upwardly .from kthe strip. Each wiresection 38 extends vthrough .the fold 48 and .this .insures `the spacing apart .of l.the wire sections along the strips in addition to their securement to .the ,strips yby 'having their ends bent over as at 44.
Figs. -6, 7 and `8 illustrate my spring liner employed with Aa different `kind of wire spring .assembly. It is apparent that this spring liner is Suitablerfor use with any conventional wire .spring assembly. In Fig. 1 coilsprings of the .hour-glass type are-shown. Y.In Figs. 6, .'7.and.8 zigzag springs 50 are shown assecured to and extending between voppositesides `of the boundary wire .frame .52 by hob ring clips 54. In Fig. .l the reinforcing stiff- `ening'members of my liner vextend between the frontand rear .margins of the seat cushion. In Figs. Band 7 the stiffening members `extend ufrom end .to end of the seat :cushion Either method of ldisposition yis suitable.
.In Fig. 7 -thespring liner is :of -substantially the :same character vas that illustrated in Figs. 1,2, -3 4and 5 except that the wire sections 3.8 arelonger and `in laddition to the strips 40 at the =ends of the wire .sections there are strips 4l which are .l
arranged intermediately the strips d0. In this figure .of the drawing, Fig. 9 illustrates va cross- .sectional view and it will be noted that .each strip 40 is folded .over .along its outer .margin as .at '4'2 and the. end of the wire `member 38 is bent ythereover .as .at 45 all .as described in connection with the construction .shown in Figs. l and 3. In this construction also the upper surface of each .strip 401is coated with adhesive as shown Vin Fig. 5 and` .is A.adhes'iye'ly secured to the overlying layer of Vburlap .35 as shown .in Fig. 8 and as described in .connection with the `structure `shown inthe first 've figures of the drawing.
Fig. 8 merely illustrates an adaptation of this liner to a zigzag spring assembly wherein there is an outer layer of upholstery fabric 30, a layer of netting 31%, a layer of wadding 32 and an overlying layer of burlap 36. The intermediate longitudinal strips 4I are formed of two layers of vbui-lap adhesively secured .together between the members 38 so as to hold .the members in spaced apart relationship. The upper surface of each .0f these layers M may be adhesively coated as are the layers 40 and as shown in Fig. 5 for adhesive vsecurement to the overlying burlap layer 3.6.
Fig. 6 .illustrates a slight modication wherein the .reinforcing lstiffening members are provided in theform of .a reversely folded continuous wire indicated as "56 'and the strips sa and al are secured thereto as shown.Y The strips lila correspond to the strips 40 previously described but .each .strip 45a is folded over the ends of the wire 56 as shown in Fig. l0 and adhesively secured .together to .securely hold the stifening wire sections in place.
