5 Claims. 1

This invention relates to mattresses, cushions,

pillows and the like, and one of the objects of this invention is to provide an article of this kind which may be made in a full or three-quarters size mattress, or in any desired size or which may be constructed with unit sections, suitable for cushions, pillows and the like, several of which sections may be joined together to provide .a full or desired sized mattress.

Another object is to provide an article of the kind described having an inner resilient unit comprising one or more cores, composed of a cellular composition and formed with compartments in which resilient springs are contained.

Another object is to provide a mattress of which the individual resilient inner units are .Joinedtogether to provide a continuous resilient unit over which and to which a cover pad is secured on either or both sides of the mattress preferably at the division points between the individual units whereby to prevent shifting of the pad and if desired to impart a multi-cushion-like efiect to the mattress.

Another object is to provide a resilient :inner unit in which the springs are contained in sealed compartments.

Another object is to provide a resilient unit in which wear members are provided at the ends of the springs to prevent excessive wear at the ends of the compartments in which the springs are contained.

Another object is to provide an article of the kind described which will not sag or spread or stretch, but will hold its original shape, and maintain an attractive appearance.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or correspondin parts.

Fig. l is a perspective view of one type of mattress embodying the invention;

Fig. 2 is a sectional view taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a plan view of a spring unit with a portion broken away, a part of a second unit being shown attached thereto;

Fig. 4 is a side elevation of the units shown in Fig. 3; and

Fig. 5 is an enlarged sectional view corresponding with a portion of Fig. 2.

Referring to the drawings, there is shown an inner core or body made up of one or more parts, as illustrated, l and 2, these being constructed of rubber, preferably sponge rubber or a latex product, so that they are comparatively resilient and elastic. When constructed of such materials the same preferably contain :a great number of passages or cells, the particular structure depending upon the type of material used. The core is :provided witha plurality of compartments or chambers 4 which if desired maybe arranged .one part-of the core and which compartments are sealed or closed wher parts l and 2 are cementedor-otherwise secured together as indicated at =3.

Arranged in each compartment or chamber 4 is-a resilient spring, 'a coiledspring 5 being shown for purposes of illustration,and thesesprings may be, if desired, enclosed in .tabric covers or bags 6, I also prefer to provide

wear members

1 and 8 in the compartments, preferably at the exterior of the spring covers fi these wear members being constructed of heavy felt, leather, canvas or other material suitable for the purpose and which tend to prevent excessive wear at the ends of the compartments *4. It may be mentioned that the springs are preferably under compression when the parts i and -2 are secured together so that they tend to maintain the inner construction in expanded position, and after each compression of the core and removal of weight on the core to expand it to the normal position shown.

If desired .a plurality *of passages 9, 1-0 and Il .or any of them are provided in the body to reduce weight as well as to improve the softness of the body.

The unit described-may be used in single units for cushions, pillows and generally :for \chairs, couches and the like. In .fact the core unit may be employed wherever it is round applicable, and provided with .a suitable cover or covers. When used in .a mattress I generally prefer to construct a plurality of inner constructions or units and secure them together, after which suitable cover and any padding or cushioning material may be added.

Referring particularly to Fig. 5,, in which portions of two units are shown in assembled relation, a strip or sheet of canvas, leather, rubber or their equivalents is arranged between the adjacent edges of the two units as indicated at M, the strip H being cemented to the faces of the two units by a cement or glue I5 :or the equivalent. In .a double raced or reversible mattress a pad or quilt is arranged :over the faces of each of the units. 'Il'iis pad may be made up in any suitable manner, as for example as a quilt consisting of an outer cover sheet .I 6, inner cover sheet I6 and filling or padding 1! of cotton, kapok, etc., the

whole being quilted together by means of stitches,

I 8 extending across the pad. Flaps 19 extend transversely of the mattress on the inner sides of the pads, and the flaps are secured to each pad'by'the line :of stitches 18, These flaps may 18 to expose the flaps l9 and member I4, and the edge portions of the flaps I9 and member 14 are brought together in overlapping condition and.

laced or stitched together by the stitches 20.. There is also provided an edge boxing for the mattress which may be of one or two plies, a twoply boxing or border being shown, consisting of inner ply 22, outer ply 23, and padding material 24, the plies and padding being secured together by stitching 25. The edges of the cover sheets 15-46, 22 and 23 are preferably brought together and covered by tape 26, stitchin or lacing 21 holding the parts together.

It will be noted that the completed mattress 30 when constructed as described has the appearance of three cushions 3| (see Fig. 1), presenting a very pleasing appearance. In making up a mattress the number of compartments and sizes, together with the strength of the springs, will depend upon the use to which the mattress is to be put. Obviously, a childs mattress would not be made as rigid or hard as one for an adult. While a single unit for a large mattress might be employed, I generally prefer to make the smaller units and secure them together. In some instances, the inner sheet I6 may be omitted, as may also the filling 24 and outer ply 23 of the boxing.

Having thus described my invention, it is! obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. In a mattress of the kind described and in combination, an inner construction consisting of two adjacent units arranged edge, to edge, each unit comprising a molded body of yieldable elastic material provided with a plurality of sealed compartments and with a spring in each compartment, an intermediate sheet adhesively secured to the meeting edges of the adjacent body units for holding them in close edge to edge relation, coverings arranged over the top and bottom faces of the units and coverings about the exposed edges thereof, said first mentioned coverings having means securing the same to said intermediate sheet adjacent the upper and lower faces of the units.

2. In a mattress of the kind described and in combination, an inner construction consisting of two adjacent units arranged edge to edge, each unit comprising a body of yieldable elasticrnaterial provided with a plurality of scaled compartments-and with a spring in each of said compartments, an intermediate sheet adhesively' 'secured to the meeting'edg'es of the adjacent'body units and extending to adjacent the faces thereof quilted coverings arranged over the topan'd bottom faces ofthe connected units and quilted coverings about the exposed edges thereofgsaid first mentioned coverings having means securing the same to said intermediate sheet adjacent the upper and lower faces of the units;

3. In a mattress of the kind describedand in combination, an inner construction comprising? "jacent units, said units being arranged edge to edge, and means securing the pads and units together at the meeting edges of the units comprising an intermediate strip adhesively secured to the units on said edges and connected to said pads.

' 4. In a mattress of the kind described and in combination, an inner construction comprising two adjacent units, each consisting of a molded body of yieldable elastic material having a plurality of sealed air containing compartments with a spring in each compartment and sealed therein, cover pads disposed over the upper and lower faces of the adjacent units, and means securing the pads and units together at the meeting edges of the units and holding the units in close edge to edge relation comprising an intermediate strip secured to the units at said edges and connected to said pads thereat.

5. In a mattress and in combination, an inner construction composed of two adjacent units each having a body of yieldable elastic matter consisting of two parts cemented together and having a plurality of separate sealed non-communicating compartments, a spring sealed in each compartment, said units being arranged edge to edge, an intermediate strip arranged between the units with its top and bottom edges exposed and secured to the adjacent meeting edges thereof, holding the units in close edge to edge relation, pads arranged at the upper and lower faces of the construction assembly, said pads each consisting of a plurality of plies with padding therebetween and united by a line of stitching, means connecting each of said pads to said strip at said lines of stitching, and a boxing extending about the periphery of the construction and secured to said pads.
