Patented Mar. 13, 1945 UNITEDV STATE o UsnIoN i Arthur Adams, Iios S. Karpen & Bros., Chicago, lll., a corporation h of Iliinois i Angeles, Calif., assignor to Application June 24, 1942, serialize. 448,205 p i l 6 claims.. (or 5-J-251) This invention relates to a. cushion, and more particularly to a soft -highly-resilient cushion structure having a plu'ralityof layers of resilient material therein. v

An object of the invention is to provide a cush- `ion of extreme softness while at the same time maintaining a relatively high degree of resiliencyI in the cushion. I Another object is to provide inl a cushion hating aspring unit as a core, a plurality of layers of material of different resiliencies and -tangular, with substantially yflat upper, lower an side surfaces.

'Y About the spring unit II is a. pair of pads I6 and Il, which are preferably formed of a resilient and only slightly-compressible material, such, for

. example, as tightly curled hair. The pads I6 and `l'lextend across the top and bottom surfaces of the spring unit IIr and cover the same. Preferably, the pad t6 is provided withdepending pordifferent degrees of compressibility. A further i object is to provide in a cushion having a spring unit as a. core, a layer of resilient material which is only slightly compressible and a second and outer layer of resilient material which is highly compressible. Y I

Another object of the invention is to provide a cushion having a plurality of `layers of curled hair, the outer layer beingu formed of loosely curled hair of high compressibility and the inner layer being formed of tightly curled hair'which is only slightly compressible. Yet another object is to provide in acushion, a spring unit and a resilient Apad extending about the same, the assembly being disposedwithin a casing which contions I8 and I9 which cover two of the sides of the spring,v unit. Similarly, the pad I'I may be 'provided with `upwardly-extending portions 2l) tains compartments `of a soft and highly-compressible material. I

Other features andadvantages of the inven-r tion will appear from the following specification and drawings, in ,which- Fig. l is a transverse sectional viewof a1 cushion i embodying the invention, the spring unit in the central portion of the cushionbeing shown inelevation and havingits casing partly broken away to show the spring therein; Fig.- 2 is a rdetail fragmentary longitudinal sectional view of the cushion; Fig;` 3 is a perspective view of the resilient pads used in the cushion; and Fig. 4 is a perspective view of the casing for the cushion showing a highly-compressible materialv disposed within the compartments inthe casing.

In the embodiment of the inventionl described herein, the cushion I0 includes a spring unit II which forms the core of the cushion. The spring unit Il may includea plurality. of helical springs I2 disposed in side-by-siderelation, with vthe up.- per and lower ends of the helicals being in the same planes to` provideat upper and lower surfaces for the unit.` .Preferably,leach of the helical springs is enclosed'vvithin a fabric casing I-3 of muslin or the like. The casings I3 maybe se; cured to each other at the'seams I4.` Preferably,

the casings and the helical springs-are'tied-'together by threads or strings I5 to form-a unitary spring body. The spring unit is preferably recand 2I which cover the other two sides of the spring unit.

'As Aseen particularly in Fig. 3, the pads I6 `and I1 may be in the form of interlaced, stitched or garnetted pads in which a suitable resilient and slightly-compressible material is secured to a fabric backing 22 by means of stitches 23. The resilient and slightly-compressible material may f comprise tightly curled Vhorse or' cattle hair, or a mixture of either or both of these with hog hair, moss, cotton, sisal, tula ber, and may, in fact, consist of a rubberized pad. At any rate, the pad should possess substantial resiliency for the cushioningeiect and at the same time should be only `slightlycompressible so that when pressure is exerted on the surface of the cushion, the spring core in :the cushion will not be felt through the padding by the user of the cushion.

. vThelpads `Iii and I1 extending about the spring unit I I? may, in turn, be enclosed by a casing 24 (Fig. 4).- The casing 24 may include side walls 25 and 2li, a top wall 2l, and a bottom wall 28. Endwalls of fabric may, if desired, be provided and may extend between the side walls 25 and 26 and top and bottom walls 21 and 2B. The fabric may be of,v any suitable material, preferably of a light material;

A second casing 29 may extend across and overlie the top Wa-ll 2'I` of the casing 24, the casing 29 preferably being spaced above the top wall 21 but being joined theretoat the edges 30 and 3|. Flexible fabric partitions 32 and 33 may be arranged at. spaced intervals between the fabric sheets24 and 29,'the fabric partitions preferably extending vertically between two sheets and longitudinallyithroughout the length of the cushion. A casingsheet 34, similar tothe casing sheet 29, may be disposed below the bottom wall 28 of the 38,may\be disposed betweenthe bottom wall and casing sheet134.

. The nexible fabric 'partitions a2 and as provide cushion. Atrthefsame time, the' matialshould be resilient. Preferably, the materialis loosely curled hair, such as horse or cattle hair, butA other similar materials, such as kapok, silk floss;

or milkweed oss, may be used.

'An outer cover or casing 4l) may extend yabout l and enclose-the entire assembly. 'The outer cover or casing 40 may include' atop walldl, side walls 42 and a bottom wall 43, the walls being joined by seams at the corners. of ,the cushion.,

When the cushion is used and pressure is,

placed upon the upper surface, the material 3S provides e. soft hishlyreempressible surface which gives the cushion the desired softness. 'The same material 3g) also provides-a certain amount ofresiliency in the cushion.4 The pads I6 and l'l are only slightly compressible and are also resilient, while the spring corek l l is highlyfresistant te Compression but possesses great resiliency. The pressure on the surface of the cushion will notcause the helical springs of the spring unit Il tobe felt through the layers of resilient mate.- rial because the slightlyw-compressible padsfl 6 and Il are interposed between the soft outer layer and the spring unit.

Although the invention has been described. in connectionl with a specic embodiment, itwill be understood that changes and modifications may be readily made without departing from thespirit and scope of theinvention.
