`releasing said pressure. Furthermore, material of this
`character offers a high resistancey against absorption of
`odor and moisture.
`'
`Embedded within the body l2 is a body 15 of a syn
`thetic resinous foam material, preferably polyurethane,
`which is highly resilient. It will be noted that this body
`is of substantial thickness but minor as compared to its
`length and breadth, and lies in the major plane of the
`pillow, more or less centrally thereof, and also (as seen
`in FIG. 4) has its edges disposed relatively close to the
`extremities of the body 12 of iilamentary material.
`The filling 12, with its enclosed body 15, is
`disposed within a cover 26 formed of woven textile
`fabric or the like, preferably of synthetic fibre such as
`Daeron, etc. This cover 20 comprises a web portion 25
`which extends around the perimeter of the pillow and
`may be of substantial width.
`Formed in the web portion 22 is one or more valve
`elements V- in the instant case, I provide one such
`valve on each side of the pillow, as seen b'est in FIG. 4.
`These valve elements each comprise a pair of flaps 28,
`29, overlying each other so as to provide a substantially
`unobstructed passage P therebetween. The outer Hap
`28, for purposes of strength and better finish, is prefer
`ably forrned as a double layer of fabric. All three lay
`ers of fabric forming valve V are preferably stitched
`together along their marginal edges as indicated by the
`numerals 3h, 3f) in FIG. 3, these stitches being continu
`ous with the stitching which secures the webbed portion
`25 to the top and bottom layers of the cover 20, as seen
`best in FIG. l.
`lt will be seen that I have provided an improved pil
`low construction which is simple and inexpensive to
`produce and which will >have many highly desirable fea
`tures. Aside from the natural resilience of the material
`which I have selected for the filler 12, the insert 15 will
`serve as a stabilizer for the filling, preventing the packing
`or shifting thereof and also, because of its high resilience
`and tendency to resume its normal planar condition, it
`will serve to restore the entire pillow to its proper position
`after distortion thereof, once the distorting force is re
`moved. Thus, the pillow will always have a neat and
`attractive appearance without the necessity for shaking,
`patting or the like, as required with other types of filler.
`The operation of the valves V will be readily apparent.
`It will be seen that they serve as two-way passages, per
`mitting escape of air from within the pillow when pres
`sure is applied to the outside of the pillow and permit
`ting entry of fresh air from the outside into the interior
`of the pillow when such force is removed.
`Various changes coming within the spirit of my in
`vention may'suggest themselves to those skilled in the
`art; hence, I do not wish to be limited to the specific
`embodiments shown and described or uses mentioned,
`but intend the same to be merely exemplary, the scope
`of my invention being limited only by the appended
`claims.
`I claim:
`1. A pillow having a cover portion and a filler, said
`filler comprising a body of filamentary synthetic fiber
`and a slab of resilient synthetic resin foam, said slab
`being disposed generally centrally in the major plane of
`said body, said slab being of substantial but minor thick
`ness compared to its length and breadth.
`2. A pillow as in claim 1, wherein the filler is formed
`of a polyester fiber, resistant to packing and lumping, and
`the slab is a polyurethane foam.
`'
`3. A pillow as in claim l, wherein the filler is formed
`of a polyester filament resistant to packing and lumping,
`and the slab is a substantially homogeneous body of
`polyurethane foam.
`4. A pillow as in claim 1, wherein the filler is formed
`
`My invention relates to pillows or sofa cushions or
`the like. An object of. my invention is to provide a
`pillow or the like having a number of advantageous prop
`erties as compared with items of similar character previ
`ously known. Thus, the filler of pillows or cushions em
`bodying my invention will have little or no tendency to
`pack, or settle, or become lumpy, marking a great im
`provement over pillows stuffed with feathers, down or
`other fillings heretofore employed; at the same time, pil
`lows embodying my invention will be soft and resilient
`to a marked degree.
`As a further object, I contemplate providing a pillow
`which will have resilient resistance to flexing so that,
`when bent or flexed out of its normal plane, it will have
`a tendency to spring back when the distorting pressure
`is removed.
`Pillows embodying my invention will be formed of
`material having a negligible tendency to deteriorate
`chemically or physically and thus will retain their desir
`able characteristics for a long time.
`More particularly, my invention contemplates a pillow
`wherein the major stuiiing comprises a filamentary body
`of spun synthetic fibre. The preferred material is a
`polyester fibre such as those known on the market under
`the trademarks Dacron, nylon, etc.
`In the preferred embodiment of my invention there
`is buried in the aforesaid filamentary stuiiìng a body of
`substantial thickness and lying in the major plane of the
`pillow and composed of a resinous foam of high resil
`ience, the preferred material for this purpose being poly
`urethane.
`A further feature contemplated by my invention is a
`pillow casing formed of textile fabric and having a
`valve-like opening therein for ventilation of the contents
`of the pillow, so as to obviate any tendency for the pillow
`to take up unpleasant odors.
`Various other objects and advantages will doubtless
`suggest themselves to those skilled in the art as the
`description proceeds.
`Referring now to the drawings forming a part of this
`specification and illustrating a preferred embodiment of
`my invention,
`FIG. l is a perspective view of a pillow embodying my
`invention,
`FIG. 2 is a sectional View taken substantially along
`the line to 2_2 of FIG. 1,
`FIG. 3 is a fragmentary sectional view on an enlarged
`scale of the casing, taken substantially along the line
`3-3 of FIG. l,
`FIG. 4 is a sectional view taken substantially along the
`line 4-4 of FIG. l, and
`FIG. 5 is a fragmentary section on an enlarged scale
`of the casing, taken substantially along the line S-S of
`FIG. l.
`The drawings show a pillow 10, which might be a bed
`pillow or a sofa cushion, etc., having a filling 12 formed
`of a random packed body of filamentary fibrous material,
`preferably of synthetic textile iibre such as a so-called
`polyester fiber and having the desired properties. Such
`material is highly resistant to decomposition, being not
`only stable chemically for long periods of time but also
`resistant to friction of one strand of fiber against an
`adjacent strand, such as might be caused by frequently
`pressing a body against the outside of the pillow and

`of a polyester filament, resistant to packing and lumping,
`and the slab is a substantially homogeneous polyurethane
`foam, and cover comprising opposed, generally similar
`face portions, a band extending around the periphery
`of the pillow and joining said face portions, and a valve
`" disposed in said band, said valve comprising overlap
`ping, substantially imperforate ilaps continuous with op
`posite portions of said band and having their free ex
`tremities spaced apart longitudinally 'of said band and
`being stitched together only along their longitudinal edges,
`thus forming a substantially continuous air channel be
`tween said flaps of substantially the Width of said band.
