Patented July 28, 1942 ARTICLE OF BEDDING George W. Gartz, Springfield, N. J., assignor to Burton-Dixie Corporation, Chicago, Ill., a corporation of Delaware Application December 14, 1940, Serial No. 370,150

4 Claims.

The present invention pertains to pillows, cushions, or other articles, which may be more or less aptly characterized as non-allergenic, in that, since some persons are detrimentally affected by breathing the allergen, pith or dust, incident to the use of feathers, down or the like, the novel pillow, cushion, or other articles constituting the subject-matter of this invention are so constructed as to preclude the emanation of such fine material from the pillow or the like while in use and without modifying the resilient and elastic properties of the pillow upon which the comfort of the user is dependent.

An important object of the invention is, therefore, to provide a pillow or the like made in such a way that the powder produced by the filling of the pillow while in service, probably due to attrition or rubbing of the feathers or particles of down on one another, and possibly also by reason of the disintegration of the feathers or down based upon their deterioration, cannot escape through the pillow cover or casing, and, accordingly, the fine dust is precluded from reaching and detrimentally or injuriously acting upon the user of the pillow.

A present improved embodiment of the invention is illustrated in detail in the accompanying drawing forming a part of this specification and throughout the views of which, for simplicity, like parts have been supplied with the same reference numerals.

In this drawing:

Figures 1, 2 and 3 show steps in the method of making the novel pillow;

Figures 4 and 5 are enlarged cross-sections on lines 4-4 and 5-5, respectively, on Figure 3; and

Figure 6 is a longitudinal section through the completed pillow.

Referring to these several views, it will be noted than on top of an outer, fiat sheet of textile-fabric H is laid a thin layer of cottonbatting I2 of the same size as sheet II and gluesized throughout its top and bottom surfaces, such part l2 being about inch thick with each of its opposite sized-faces continuous or imperforate.

Then on top of such stratum I2 is deposited another inner textile-fabric sheet 13 of the same size, whereupon the three strata are stitched together along one margin at [4.

Two of such triplicate members of equal size having been made in this manner, they are superimposed on one another in register with with one another, as shown in Figure 2, except that for clarity one corner of one such member is depicted as folded back to disclose the other underlying threefold member.

Thereupon, the two treble members, that is the six strata, are stitched together along the remaining three margins l5, It and I1 and then such stitched article with one end open or unstitched is reversed or turned inside out as presented in Figures 3, 4 and 5.

Such casing or envelop is then filled through its open end with feathers, down, kapok, or other resilient and elastic material l8, after which the two upper and lower members are stitched together along a line I9 (Figure 6) at the mouth of the sack or casing thereby securely and effectively closing its previously open end and providing a completely enclosed filling surrounded by the cotton-batting layer and the textile-fabric sheets.

A pillow has to have a certain measure of resiliency or buoyancy to give a reasonable degree of comfort to the user, and the new pillow incorporating the present invention has such characteristic in adequate amount, due to the elasticity of the filling and to the fact that the three strata of the cover allow air to escape therethrough thus permitting compression of the filling under weight imposed thereon and admit air to pass inwardly therethrough to permit ready expansion of the filling when freed from its load resting thereon.

Such air expelled from and drawn into the pillow passes through the cotton-batting layer and its sized surfaces, but any feather, down or comparable dust, powder or pith in the pillow cannot pass through the inner sized surface of the cotton-batting stratum which acts as a filter, thus preventing such possibly allergenic feather or down material from coming into contact with the occupant of the pillow.

Experience has demonstrated that such surface of the batting remains unbroken over a long period of service, even though the pillow is frequently deformed more or less while in use.

If, in time, such inner sized surface becomes injured or deteriorated in such a manner as to allow the specified dust to pass through it, the cotton of the layer and its outer sized surface then function as the filtering media and the pillow continues thereafter for a long time to give effective and efficient service.

In this connection it is to be noted that the intermediate filtering means is attached to the inner and outer more or less porous textile-fabric their two outer sheets H, H in direct contact casings only around the border of such means,

thus leaving the sized surfaces of the cottonbatting to vary in shape as occasion requires and without substantial danger of rupture or breaking.

Inasmuch as none but the marginal parts of the cotton-batting are stitched and these are inside of the outer casing, there is no danger of the feather or down dust or powder passing outwardly through the small openings through which the thread of the stitching extends into the outer air and the entire surface of the filter unattached inwardly of its border functions efficiently to perform its useful work.

In view of the fact that the cotton-batting is itself resilient, a somewhat lesser amount of feathers or of the relatively-expensive down may be used as a filler without material or objectionable decrease in the elasticity of the pillow as a whole.

Another distinct advantage resulting from the employment of the present invention resides in the reality that, due to the softness or insulating quality of the glazedwadding, the pillows may be filled with cheaper grades of feathers than would otherwise be used and without the consequent objection of feeling the quills or harshness prevalen't in such lower type of feathers; in other words, the cotton-batting acts as an insulator, and, although the pillows may be filled with a less expensive grade of feathers, on their exteriors they will have a nice, soft, smooth feel or touch.

Those acquainted with this art will readily understand that the invention is not necessarily limited and restricted to the precise and exact details of construction presented, since these may be modified within reasonable limits without departure from the heart and essence of the invention as defined by the appended claims and without the loss or sacrifice of any of the material advantages and benefits accruing from the employment of the invention.

I claim:

1. In an article, adapted to be used by a person occupying a bed or the like, having an outer closed porous cover, an inner closed porous casing inside of said cover, an elastic filler-body of feathers, down or the like, inside of said casing, and means securing said casing and cover together around their entire margins, the novel features of a filter-envelope of cotton-batting between said cover and casing and enclosing said filler-body, said cotton-batting being sized throughout at least one surface to render the article non-allergenic to persons allergic to said filler-body, the full length of the margin of said sized cotton-batting filter-envelope being secured around the margin of at least said casing or cover.

2. The novel features in the article set forth in claim 1 and wherein said filter-envelope is otherwise free from attachment.

3. The novel features in the article set forth in claim 1 in which said cotton-batting filterenvelope is sized throughout both of its surfaces.

4. The novel features in the article set forth in claim 1 in which the article is of general rectangular shape and in which said cover, casing and filter-envelope each consists of top and bottom parts with three sections of the margin of each of said parts inturned and all secured together inside of said cover, the remaining marginal sections of said parts being inturned and secured together at the exterior of said article.
