4 Claims.

This invention relates to a mattress.

The present application constitutes a division of our co-pending application Serial No. 31,490 for Mattress, filed July 15, 1935, which has even- 5 tuated in Patent No. 2,147,348, issued February 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

.0 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 efiicient manner. A further object is to provide a mattress structure 5 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 suiti able construction. In the illustration given, it consists of rows of hour-glass springs l0 connected by helicals II. If desired, the individual springs may be enclosed within fabric pockets.

About the spring structure A is folded a blanket l 2 of cotton or any suitable filling material.

The main casing B consists of a border strip 43 having its ends stitched to the fabric sheets I 4. Simultaneously with the stitching of the border fabric 13 to the sheets Hi, 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 it, M and i5, being designated in the drawings by i 5=-. The border strip I3 is provided with 2. padding l6 of cotton or other suitable material stitched to the strip l3.

In the process of forming the mattress, we first stitch the ends of border strip l3 together with the tie strips of the cushion members 0 to the main casing sheets l4. Next we place the main casing upon a filling machine which inserts the spring structure blanket l2 thereon to the extent that the main casing is stretched taut. We next place a cushion filling material ll of soft cotton or other suitable material draw fabric cover strips 18 about the filling material .ll, stitching the ends of the cover l8 and the fabric strips l5 together and by means of a binding tape I 9.

The structure resulting from the foregoing.

provided with any suitable number of stitch eyelets 22.

'I'he finished mattress will have a taut main terminal or end rings of which extend substantially to the border of the main casing. In conin 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 for 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 Ii], and just below the free edge portion of the cushion C. The tightly drawn main serves to hold the roll 24 closely against the end spring and thus provides a compact supporting structure below the edge of cushion C.

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.

In the structure shown in Fig. 5, both longiabout the sheets I4 and then A together with the filling tudinal 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 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 at the prior art.

We claim:

1. In a method of forming a mattress, the steps of stitching the edges of a main casing sheet to one edge of a casing border strip and an edge of a cushion tie strip, stitching the edges of. another main casing sheet to the other edge of the casing border strip and an edge of a cushion tie strip to form a casing open at one end, inserting a spring structure enclosed in a filling blanket between said casing sheets and said border strips, closing the open end of said main casing, applying filling material on one side of said main casstitching the edges of a cushion cover over said filling material to the edges of the adjacent tie strip, applying filling material on the other side of said main casing, and stitching the edges of the cushion cover thereover to the edges of the adjacent tie strip.

2. In a method of forming a mattress, the steps of stitching the edges of a main casing sheet to an edge of a casing border strip and an edge of 2.

cushion tie member, stitching the edges of a second main casing sheet to the other edge of said casing border strip to provide a hollow casing open at least at one end, inserting a spring structure enclosed in a filling blanket within said hollow casing, applying cushion filling material over said main casing, and stitching the edges of a cover to the edges of said cushion tie strip.

3. In a method of assembling a mattress, the steps of stitching the edges of a main casing sheet to one edge of a casing border strip and an edge of a cushion tie strip, stitching the edges of another main casing sheet to the other edge of the casing border strip to provide a casing open at one end, inserting a spring structure enclosed in a filling blanket between saidcasing sheets, closing the open end of said main casing, applying filling material upon said first-mentioned casing and within said cushion tie strip, and stitching the edges of a cover to the edges of said cushion tie strip.

4. In a method of the character set forth for forming a mattress having a central spring structure, the steps of stitching the edges of a main casing sheet to one edgeof a casing border strip and an edge of a cushion tie strip, stitching the edges of another main casing sheet to the other edge of the casing border strip and an edge of a cushion tie strip to form a casing open at one end, inserting a spring structure between said casing strips and said border strips, closing the open end of said main casing, applying filling material on the outer side of each of said main casings, and stitching the edges of cushion covers over said filling material to the edges of said tie strips.
