2 Claims.

This invention relates to a mattress.

An object of the invention is to provide a mattress of improved construction and in which the spring core is enclosed within a main casing, and in which flexible cushion structures are attached to top and bottom sides of the main casing containing a spring core, the attachment being accomplished in a novel and eiiicient manner. A further object is to provide a mattress structure of sturdy and simple construction which may be assembled with few operations and at a minimum of expense. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in a preferred embodiment, by the accompanying drawings, in which- Figure l is a broken perspective View of a mattress embodying our invention; Fig. 2, a broken side elevation and part sectional View; Fig. 3, a View similar to Fig. 2 showing one modification; Fig. 4, another view similar to Fig. 2, but showing a second modification; and Fig. 5, another view similar to Fig. 2 showing a third modification.

In the construction shown in Figs. 1 and 2, A designates a spring structure; B, a main casing member enclosing the spring structure A and padding therein; and C, a cushion structure secured to the main casing B.

The spring structure A may be of any suitable construction. In the illustration given, it consists of rows of hour-glass springs I0 connected by helicals II. If desired, the individual springs may be enclosed within fabric pockets.

About the spring structure A is folded a blanket I2 of cotton or any suitable lling material.

The main casing B consists of a border strip I 3 having its ends stitched to the fabric sheets I4. Simultaneously with the stitching oi the border fabric I3 to the sheets I4, we stitch the tie strips I5 forming a part of the cushion member C, as illustrated more clearly in Fig. 2 the stitching connecting the members I3, I4 and I5 being designated in the drawings by I5a. The border strip I3 is provided with a padding I6 of cotton or other suitable material stitched to the strip I3.

In the process of forming the mattress, we rst stitch the ends of border strip I3 together With the tie strips I 5 of the cushion members C to the main casing sheets I4. Next we place the main casing upon a filling machine which inserts the spring structure A together with the filling blanket I2 thereon to the extent that the main casing is stretched taut. We next place a cushion filling material I7 of soft cotton or other suitable material about the sheets I4 and then draw fabric cover strips I8` about the filling material I "l, stitching the ends of the covers I8 to the fabric strips I5 together and by means of a. bind- 5 ing tape I9.

The structure resulting from the foregoing process aifords a taut main casing which snugly houses the filling and spring core, while at the same time a soft and exible cushion body C is 10 supported about the corners of the main casing.

'Ihe mattress may be tufted in any suitable manner. In the illustration given in Fig. 2, the tufting buttons 2|) engage the cushion covers I8, and the tie members 2| extend through the filling 15 Il, main casing sheet I4, and the inner filling and spring structure.

If desired, the padded border fabric I3 may be provided with any suitable number of stitch eyelets 22. 20

The finished mattress will have a taut main casing snugly enclosing a spring structure, the terminal or end rings of which extend substantially to the border of the main casing. In contrast with the taut main casing, the flexible soft 2 cushion members C lie on each side of the casing and may be handled very much as a pillow or soft cushion. It will be observed, however, that the tie-strip I5, which is secured to the taut casing I4, confines the outer edge of the cushion mem- 30 ber C so that it is held substantially over the end or terminal springs of the spring structure A. By this means, the cushion is supported in the position shown in Fig. 2.

The border of the main casing may also be quilted or provided with rolls whereby additional support is provided Vfor the free edge portion of the cushion C. As shown in Fig. 3, the padded border may be provided with stitches 23 which form relatively rigid rolls 24 adjacent the end springs III, and just below the free edge portion of the cushion C. The tightly drawn main casing B serves to hold the roll 24 closely against the end spring and thus provides a compact supporting structure below the edge of cushion C. 45

In the structure shown in Fig. 4, longitudinal stitches 25 are formed between the eyelets 22 and drawn so as to bring the eyelets 22 slightly toward each other, thus forming vertical ribs between the eyelets 22. 50

In the structure shown in Fig. 5, both longitudinal stitches 25 and vertical stitches 26 are employed to form vertical ribs 21.

While in the illustrations given in Figs. 4 and 5, we have shown two methods of providing vertical 55 fluting or ribs by which the padded border is stiffened to provide a support for the flexible cushion member C, it will be understood that many other means may be employed for this purpose. Instead of one or two rows of eyelets 22, there may be three or more rows, and the eyelets may be drawn together by stitches of any suitable type to provide reinforcing ribs.

The foregoing detailed description has been given for Clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in View of the prior art.

We claim:

1. A mattress comprising: a spring structure enclosed in a blanket of filling materials, a casing border strip about the edge of said spring structure, a casing sheet adjacent said lling material, a cushion tie strip adjacent said casing border, said casing sheet having its edges stitched together with the edges of said border strip and tie strip at points rearward of the edge of said spring structure, filling material over said casing sheet, and a cushion cover over said last-mentioned filling material and stitched at its edges to an edge of said tie strip.

2. A mattress comprising: a spring structure,

a casing border strip about the edge of said spring structure, casing sheets on each side of said spring structure, cushion tie strips adjacent each edge of said casing border, each of said casing sheets having its edges stitched together with the edges of one of said tie strips and with an edge of said border strip at points rearward of the edge of said spring structure, layers of lling material on the outside of said casing sheets, and cushion covers outside said layers of filling material, each having its edges stitched to the other edge of one of said tie strips.
