'1 Claim. (Cl. -337) This invention relates to pillows and, more particularly, to a pillow for resting the head of the user.

In the manufacture and use of pillows, softness, or ease of deformability, and resiliency or nerve are considered to be of primary importance. Also, freedom from the feel of the filling material and from the annoyance of resilient bounce inherent in many pillows are also desirable properties in a pillow.

Furthermore, materials such as feathers, down, and the like heretofore generally used as cushioning and stufling material for pillows and similarly cushioned articles tend to give off dust to which many persons are hypersensitive or allergic, and a selected amount of such materials has no fixed volume by reason of the individual particles thereof being flulfy and tend to spread and become packed.

It is, therefore, an important object of the present invention to provide a pillow of improved softness and resilience.

Another object of the invention is to provide a pillow of the feather and down type that is non-allergic.

Still another object is to provide a pillow having a feather and down filling with a case that filters out the feel of the feathers while retaining the luxurious comfort of fluify down.

A further object is to provide a pillow of the feather and down type with a case that filters out the rubber bounce inherent in such pillows yet retaining the lasting resiliency of the pillow.

A still further object is to provide a pillow of the feather and down type with a case that filters out various allergy causes inherent in such pillows.

It is further proposed to provide a pillow having a feather and down filling with a case having a foam rubber lining that filters out dust particles to make the pillow truly non-allergic, that retards the growth of bac teria, that prevent mildew, that prevents penetration of perspiration into the filling and that makes the pillow long lasting.

It is also an object of the invention to provide a pillow of this kind that is sanitary, readily laundered in Washing and drying machines, and that retains its shape.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a top plan view of a pillow embodying one form of my invention.

Fig. 2 is an enlarged vertical sectional view taken on the plane of the line 22 of Fig. 1.

Fig. 3 is an enlarged sectional view taken on the plane of the line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 1 but showing a pillow embodying a modified form of the invention.

Fig. 5 is an enlarged sectional view taken on the plane of the line 55 of Fig. 1.

Referring in detail to the drawings, a pillow embodying the first form of the invention is illustrated in Figs. 1 to 3, inclusive, and designated at 10. The pillow consists of a bag-like hollow body, rectangular in plan and 2,956,291 Patented Oct. 18, 1960 "ice bulbous in cross section. The body comprises an outer case or envelope formed by two rectangular sheets 11, 11 and two sheets 12, 12 of foam rubber. The rubber sheets serve as linings for the fabric sheets. The superposed edges of the fabric and rubber sheets are turned inwardly and a strip of tape 13 or other suitable piping material is turned upon itself and its overlapping long edges fastened to one of the inturned edges of one of the fabric sheets 11 by a row of stitching 14, with its looped end projecting outwardly providing a piping 15. Opposed narrow strips 16, 16 of fabric are bent longitudinally and superposed on the bent inturned edges of the lining sheets 12, 12. A row of stitching 18 fastens the inwardly turned edges of the sheets and the strips 16, 16 together.

The bag-like body is filled with material, preferably feathers and/or down material, indicated at 20. The amount of filling or cushioning material is preferably such that the outer case or envelope is as nearly completely filled as possible to the configuration indicated in Fig. 1 without initial compression of any of the particles or elements comprising the material, or in other words, the case is loosely filled.

The outer case or envelope is formed of any suitable fabric material such as linen or cotton sufiiciently close- 1y woven to be substantially impervious to the passing of dust particles therethrough under normal usage.

The cellular formation of the foam rubber linings permits the air to flow from the interior of the body and at the same time the foam rubber has the property of absorbing dust particles carried by the air. Furthermore, the foam rubber permits the user of the pillow to feel the flufiy feathers yet any sharp points on the feathers are deflected by or stick in the foam rubber. It has also been found in practice that the foam rubber retards bacterial growth, prevents mildew and prevents perspiration from seeping through to the filling material thereby ensuring a long-lasting life for the pillow.

The modified form of pillow 10 shown in Figs. 4 and 5 differs from the pillow of Figs. 1 to 3, inclusive, in that the body of the pillow is of quilted formation as indicated at 22. Furthermore, the linings 12', 12' are provided with spaced perforations 23 to facilitate passage of air therethrough.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent An improved pillow comprising a closed casing formed by an outer porous sheet of woven fabric secured to an inner sheet of resilient, cellular, porous foam rubber, and a filling of feathers in said casing, the porous rubber and fabric sheets permitting air to flow therethrough while preventing passage of dust particles and protrusion of sharp points of the feathers through the sheets, the resiliency of the rubber sheet providing a yielding enclosure for the feathers and a cushion against said sharp points.
