MATTRESS Filed May 25, 1939 I ATTORNEY Patented Oct. 1, 1940 2,216,537 1 MATTRE SS Joseph Martin, Laurelton, N; Y., assignor toUnited States Cabinet Bed 00., Brooklyn, N..Y., a corporation of New York io s! 25, 1939, Serial2'75,5 75 i Y 7 5Glaims. (Ci."5' 351 )f. V v

This invention relates to mattresses'in general and more especialy to spring mattresses having two paddings composed of felt with an intervening section of coil springs. v

Among the objects of the present invention, it is aimed to provide an improved spring mattress having a pad composed of a plurality of sections one placed upon the other. I

It is still another object of the invention to provide an improved spring mattress having a padding composed of a plurality of layers, felt or the like, .one placed upon the other and in which the general direction of the fibres 'of the alternate layers and the fibres of successive layers extend transversely to one another.

' It is .still further another object of the present invention to provide an improved spring mattress having a padding composed of a plurality of layers of felt or. the like, each attached to a muslin covering in which the stitches attachi'the. muslin to the, felt layerand successive layers extend transversely to one another.

These, and other features, capabilities and advantages of the invention will appear from the subjoined detail description of specific embodiments thereof illustrated in the accompanying drawing in Which Figure 1 is a fragmental section of a spring mattress made according to the present invention.

Fig. 2 is a fragmental plan of the mattress with portions broken away.

Fig. 3 is a fragmental section of another embodiment of the present invention.

In the embodiment shown in Figs. 1 and 2 the coil spring unit I is conventional consisting essentially of a plurality of coil springs 2 connected to one another and to intervening supporting wires 3 and bordering wires 4 which in turn are preferably as shown, provided with an upper and lower fabric coverings 5 and 6 and padded units I between the upper and lower coverings 5 and 6 as shown in Fig. 1.

The novel feature of the present invention resides mainly in the padded units 8 and 9 now to be described. These padded units 8 and 9 according to the present invention are composed of a plurality of padded layers. In the present instance, each of the units 8 and 9 is illustrated as composed of four layers such as the layers It), I I, I2 and I3. In the preparation of these layers, a section of felt is passed through a carding ma-. chine with a sheet of muslin l4 and I5 above and below the same and the carding machine then forms a plurality of parallel stitches 16 through the three elements secure the two muslin sheets 14 and I5 to the intervening layer of felt ll. In Fig. .1 preferably theiouter layer II], in place of the muslin sheet l4,-has an outer sheet of ticking I8 attached thereto by the carding ma-i I chine asushown; 'When a layer of felt passes through. a. carding .machine according to the practice hertoforefollowed the fibres extend more orfiless longitudinally in the general direction of the path of movement and therefore with the row of stitches. In the preparation of the first layer It according to the present invention, however, the felt I! is passed-through the carding machine with the fibres extending in the general direction transverse to the path of movementso ll that the stitches will be formed transverse .to the general direction. ofthe fibres. Furthermore according to the embodiment in Fig. 1, the stitches l6 of the first layer lll will extend transverse 'to thelength' of thezrnattress. In preparing the sec- 20 ,ond-ilayerl I, the-felt layer is similarly passed through-the cardingtmachine with the general direction of its fibres transverse to the direction of movement so that the stitches of the second layer, when attaching the muslin sheets 'to opposite sides thereof, still extend transverse tothe general direction of the fibres. However, the fibres of the second layer II will extend in a general direction transverse to the length of the mattress and the stitches extend longitudinally of the mattress. The third layer I2 will have the general direction of the fibres again extend longitudinally and the stitches transversely of the mattress, similar to the arrangement of the layer Ill, and the layer l3 will have its stitches and felt fibres again arranged similar to that of the second layer II. After each padded unit 8 and 9 is prepared as aforesaid, the outer layer IQ of the unit 9 similarly having the mattress ticking 20 secured to it as the ticking I8 is secured to the layer l0, then the beaded ends 2| and 22 of the outer layers l0 and I9 are connected to one another by the ends of an intervening fabric covering 23 as shown in Fig. 1.

It has been found that satisfactory padding units according to the present invention will also result when the felt layers are each attached to .a single sheet of muslin as shown in Fig. 3, in which case, however, again the upper outer layer 24 will have the muslin sheet 25 and the mattress ticking 34 stitched thereto by the rows of stitches 26 transverse to the direction of the fibres, and also transverse to the length of the mattress, the next layer 21 will have its sheet of muslin 28 stitched thereto by rows of stitches 26 extending v transverse to the general direction of the felt fibres but longitudinally of the mattress, the layer 29 and its muslin sheet 30 stitched similar to the arrangement of the layer 24 and the layer 3| and its muslin sheet 32 stitched similar to the arrangement of the layer 21.

With the practice heretofore followed, it has been found that when the mattresses extend in the general direction of the fibres naturally if the fibres all extend in the same general direction there will result a compressed portion where the most weight supporting wear is exercised. With the present invention, with the fibres in successive layers extending in directions transverse to one another and similarly the stitches of successive layers extending transversely to one another, the spreading out tendency of the successive layers will counteract one another sufficiently, materially to reduce the objection noted with the mattress made according to the practice heretofore followed thereby materially increasing the fiufiy life or good condition of the mattress.

. It is obvious that the muslin sheets l4, l5 and 28 serve as protective sheets for their respective layers.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended s claims.

I claim:

1. A mattress including two padded units and an intervening coil springunit, each padded unit including a plurality of felt fibre layers, a. protective sheet for each layer, rows of stitches attaching each protective sheet to its layer, and extending transverse to the general direction of the fibres of its layer, the fibres of successive layers extending transverse to one another.

2. A padded unit for a coil spring unit consisting of a plurality of superimposed fibre layers, the general direction of the fibres of successive layers extending transverse to one another, a protective sheet for each layer, rows of stitches attaching each protective sheet to its layer, and extending transverse to the general direction of the fibres, the rows of stitches of the successive layers extending transverse to one another.

3. A padded unit for a coil spring mattress consisting of a plurality of superimposed fibrous layers, a protective sheet on each side of each fibrous layer, rows of stitches attaching the protective sheets of a layer to its layer and extending transverse to the general direction of the fibres thereof, the rows of stitches of successive layers extending transverse to one another.

4. A padded unit for a coil spring mattress consisting of a plurality of felt fibre layers with the general direction of the fibres of successive layers extending transverse to one another, a muslin sheet for each layer, rows of stitches attaching each muslin sheet to its layer with the stitches extending transverse to the general direction of the fibres thereof, the rows of stitches of successive layers extending transverse to one another.

5. A mattress including two padded layers and an intervening coil spring unit, each padded unit including a plurality of felt fibre layers with the general direction of the fibres of successive lay ers extending transverse to one another, a muslin sheet for each layer, rows of stitches attaching each muslin sheet to its layer and extending transversely to the general direction of the felt fibres thereof, the rows of stitches of successive layers extending transverse to one another, a ticking sheet for the outer face of the outer layer the rows of stitches of the outer layer attaching the ticking sheet to such layer, and ticking extending from the ticking of one outer layer to the ticking of the other outer layer and connecting the two together.
