`1 Claim. (Cl. 5-337)
`The present invention relates to a pillow covering and
`in particular to a waterproof covering which is con
`structed to not only protect the pillow ticking from getting
`wet, but from stains and damage.
`The primary object of the invention is to provide a
`cover for a pillow ticking that will keep the pillow ticking
`and contents dry and at the same time allow the pillow
`to have ample breathing in changing its cubic area by
`altering its shape during its normal use.
`A further object of the invention is to provide a cover
`which is simple in both its construction and use.
`While several objects of the invention have been pointed
`out, other objects with certain uses and advantages may
`be referred to as the nature of the invention is more fully
`disclosed.
`‘
`The preferred form of the invention is illustrated in the
`accompanying drawings and described in the speci?cations
`to follow:
`FIGURE 1 is a perspective view of the cover in place
`over a pillow ticking and its contents.
`FIGURE 2 is an elevational view of the side of the pil
`low covering.
`FIGURE 3 is an end view of the same.
`FIGURE 4 is an enlarged fragmentary perspective
`view of one corner of the cover as it is when ?rst con
`structed, that is, in an inside-out position.
`FIGURE 5 is a diagrammatical view of a corner of the
`cover showing the manner in which the edges of the cover
`are stitched together.
`FIGURE 6. is an enlarged fragmentary sectional view
`of a'corner section of the pillow showing the relationship
`of the ticking, cover and the outer pillow casing.
`In reference to the drawings, like numerals are used
`to point out like and similar parts throughout the several
`views of the drawings.
`The cover A is adapted for use with a pillow having a
`porous ticking ?lled with compressible and expansible
`material, the cover is adapted to ?t snugly about the
`ticking of the pillow as illustrated in FIGURE 1.
`The cover is made from a flexible piece of waterproof
`cloth or other ?exible waterproof sheet material having
`faces 10, 10a and end portions 100 and 10d. The cover
`sheet is preferably of ‘such size as to lay close to the
`surface of the ticking 12, and seamed along at least one
`of its lateral edges as shown at 14- in FIGURE 1.
`It is
`also possible to form the cover from a continuously
`formed tube of material (not shown) from which the
`covers may be cut off at predetermined length.
`The covering is of bag-like form having corresponding
`or opposite face portions 10 and 10'. They are usually
`of quadrangle form having lateral sides 10a and 10b and
`ends 100 and 10d.
`
`2
`The end 10d is provided with a zipper fastening 16
`which is stitched to the edges of face portions 10 and 10a
`of the cover for providing a means for opening and clos—
`ing the cover for inserting, or removing the pillow.
`Along one of the other sides of the cover, there is pro
`vided preferably a rather coarse netting 18. This net
`ting 18 is stitched to the two face edges of the cover
`by stitches 20, extending preferably the full width of the
`pillow. While the netting is shown positioned at the end
`opposite the zipper, however, it may be inserted along one
`of the other sides if more convenient.
`In use, a conventional porous pillow casing 22 is pref
`erably used over the cover and generally ?ts the cover
`more loosely than the cover ?ts the pillow ticking 12. The
`three layers, the ticking, cover and pillow casing is illus
`trated in FIGURE 6.
`The cover being of waterproof material such as the
`present plastic coated fabrics keeps the pillow ticking and
`?ller clean and from becoming contaminated. It also
`keeps the pillow ticking from becoming stained or dis
`colored, and has a 'very practical application in everyday
`use. The cover is particularly effective in hospitals and
`other places where soiling or contamination of the pillow
`would mean frequent replacing of the pillows.
`With all the above advantages previously pointed out,
`the pillow has a very free breathing action due to the net
`ting 18 which is not possible with small breathing holes
`‘generally used in waterproof covers presently in use and
`disclosed in the prior art.
`While the invention is shown and described in a
`specific manner, it is not intended as a limitation as the
`scope of the invention is best de?ned in the appended
`claim.
`I claim:
`A covering for a pillow having a compressible and
`expansible ?lling and a porous ticking extending about
`the ?lling comprising, in combination:
`(a) said covering having a body portion with opposite
`face portions of waterproof material extending snug
`ly over the ticking;
`(1b) a zipper fastening attached along the edges of the
`opposite face portions at one end of the cover for
`closing and opening one end of the cover for insert
`ing and removing the pillow;
`(c) a porous netting attached along the edge of the
`face portions opposite the end carrying the zipper for
`allowing for ingress and egress of air into and out
`of the pillow when the cubic area of the pillow is
`changed in the normal use thereof.
