PILLOW AND SIMILARLY CUSHIONED ARTICLE 'Filed June 27. 1940 Patented Oct. 6, 1942 PILLOW AND SIMIIARLY-CUSHIONED ARTICLE Regner E. Madsen, ChicagoJll., assigner to Protectoseal Company of America, Inc., Chicago, Ill., a corporation of Illinois Application June 27, 1940, Serial No. 342,655
The invention relates to cushioned articles such as pillows, mattresses and bassinettes, and par-` ticularly it relates to cushioned articles of the kind. described having `thicknesses normally less than their length' or width.
Anelongatedv pillow casing of selected dimensions, if filled or stuffed to its unrestricted capacity with cushioning material, is distended thereby to, substantially cylindrical shape and likewise, ifL the casing is vapproximately square and similarly lled or stuifed to capacity, it is distended toI substantially spherical shape or ccnguration. It lis' in general desirable and for most purposes practicable that pillows and like cushioned articles have thicknesses less than their length or width, and the invention has among its objects the provision of novel means adapted to limit the maximum possible thickness of a cushioned article of the kind described to dimensionssubstantially less than its width or length and, without impairing its cushioning qualities or preventing it from being crushed, bent, turned, reclined, doubled or otherwise distorted as the user may desire.
Since materials such as feathers, down, and thes like hitherto generally used as cushioning material forV pillows and similarly cushioned articles tend to give oi dust to which many persons are hypersensitive or allergic and a selected. amount of such materials has no iixed volume .by reason of the individual particles thereof rbeing ufiy and tending to spread out, the, invention has as another of-its objects the provision of dustless cushioning material made up of `a .plurality of particles, elements or iiakes preferably of various sizes, the individual particles being characterized by their having a normal xedconguration and the lack of any tendency to expand or change their shape other than when they arecompressed or otherwise distorted. Among the materials adapted for cushioning purposes and having the above designated desirable characteristics may be included cellular latex rubber, sponge rubber, or any other form of rubber or material of similar texture and having like qualities and. resiliency when compressed or otherwise distorted wherebyV when a casing or other; single receptacle is lled to capacity therewith,4 such materials are undistorted and have theirmaximum initial resiliency and cushioning qualities.
A further object of the invention is. the pro- Vision of a pillow or similar. cushioned article having cushioning material so enclosed and of a Icharacter such that the .material does-not dis- 55 th'enet-like casingl I3 `to relatively `large particles-- seminate any dust particles tov which the user" may behypersensitive or allergic.
Another object of the invention is theprovision, in. pillows having a plurality of dustless, porous, resilient par-ticles as cushioning material, of an. improved receptacle or casing for such materials whereby the casing does not retard or interfere with the yielding or so-calledbreathing prop-l erties of the enclosed material.
A further object of the invention .is the pro-vv vision of improvements in pillows and similar ar-A ticlescomprisingan inner cushion and an outer f closed slip, the improvements adapting thepillow to-be washed and dried intact, centrifugally'- or otherwise without aifecting its normal -con figuration, cushioning or exible qualities.
A-urther object of the invention is the provision of: improvements in pillows Y and similar cushioning articles adapting the same tol be dis- :torted and to remain in any suitable or desired distorted position or conguration and to retain 1 their full flexibility and cushioning qualities unimpaired in any'and all such positions.
their intended purpose.
Many other objects and advantages of the construction herein shown and described will be obvious to thosefskilled in the art.
Referring now to the drawing wherein like reference characters indicatelike or correspond-- ingparts:
Fig. 1 is a plan view partially in section of a pillow embodying the principles of the invention;
Fig. 2 is a View along the line 2 2 of Fig.1; and
Fig. 3 is a view along the line 3-3-of Fig. 2.
latex,` and sponge rubber or any other form of rubber prepared for this purpose by grinding, shredding, cutting, flaking and the like, is preferablyused, the particles being of any suitable size from the smallestrwhich may be retained by Referring now more particularly to the drawing, the invention is illustrated as embodied in a l having the requisite cushioning properties. The amount of cushioning material used varies with the dimensions of the pillow and is preferably such that the casing I3 is as nearly completely filled as possible to the configuration indicated in Figs. 2 and 3 without initial compression of any of the particles or elements comprising the material, or in other words the casing is loosely lled.
The outer slip is constructed of any suitable fabric material such as linen or cotton suiciently closely woven to be substantially impervious to the passing of dust particles therethrough under normal usage. The slip has a closely stitched marginal hem I4 preferably inturned along one longitudinal edge and across one end, the hem being out-turned across the other end for convenience in opening and closing to permit insertion and removal of the casing I3 containing the cushioning material I2.
The casing material I3 may be closely woven but it preferably consists of interwoven threads which may be of any desired color and of any texture suitable for weaving. The threads comprising the casing material I3 may be as closely spaced as 140 to 180 per inch or the casing may be coarser and the spacing of the threads much greater, but sufficiently close that the casing retains the finer particles of the cushioning material I2. The wider or net-like spacings of the threads comprising the casing I3 are desirable as they permit free ingress and egress of air to the cushioning material I2, or in other words, the so-called breathing characteristics of the cushioning material are not impaired by an openwork casing.
The casing I3 may be made from a single sheet of material cut and folded to a double thickness of rectangular shape as shown With its contiguous edges connected by stitches to provide an out-turned hem IB, or if preferred, the sheet may be cut and similarly folded to provide a casing having round corners.
A casing I3 of given or selected lateral and longitudinal dimensions, if lled with cushioning material to its maximum capacity, will be distended to a substantially cylindrical shape instead of being relatively flat as ordinarily made. As shown in Figs. 2 and 3 of the drawing, the capacity of the casing I3 is limited by and prevented from being distended to cylindrical form when filled to such limited capacity by means of bands or tie members connecting opposite sides of the casing. The tie members are provided to limit the permissible amount of spread or spacing between the opposite sides of the casing I3 and thereby tocontrol the amount of distension and the thickness of the casing and of the pillow I as a whole.
Only two tie members respectively designated by the numerals I1 and I8 are shown in the drawing, but obviously, any other number may be provided if desired. The maximum amount of uncompressed cushioning material that a casing I3 equipped with the tie members I1 and I8 is adapted to contain obviously depends not only on the longitudinal and lateral dimensions of the casing, but also upon the lengths and the arrangement of the tie members |1 and I8. Referring to Figs. 2 and 3, wherein the casing I3 is illustrated as filled with cushioning material I2 to its said limited maximum capacity with the elements or flakes comprising the cushioning material uncompressed, it is apparent that the tie members I1 and I8 tend to hold the casing I3 to the configuration shown when so filled. The
opposite ends of each of the tie members II and I8 are fastened together in any suitable manner such as by tying or by stitching to form corresponding continuous members of suitable length. The tapes or bands I9 respectively stitched or otherwise fastened to the opposite sides of the casing I3 and similarly spaced from the marginal edges thereof are arranged in the form of rectangles preferably of the same dimensions. Similarly, two tapes or bands 28 are respectively fastened to opposite sides of the casing I3 and extend longitudinally thereof and are preferably so positioned as to bisect the rectangular spaces provided by the bands I9. A plurality of loops 2| are fastened to each of the bands I9 and 28. The tie member I'I forms a lacing extending through a loop 2| fastened to a band I9 on one side of the casing, then through a corresponding loop 2| fastened to a band I9 on the other side of the casing. The tie member I'l is in turn laced through all of the loops 2| of the bands |9, the lacing being as shown in Fig. 2 and being of such a length that it is substantially taut when the casing is filled to desired capacity without compressing the cushioning material I2 at the thickness and for the general configuration of the casing shown. Likewise, the continuous tie member I 8 is laced through the casing I3 by extending it through all of the loops 2| on the oppositely positioned bands 20, the arrangement being as shown in Fig. 3 and similar to the arrangement of the member II. The end loops 2| on the bands 20 are spaced slightly away from the contiguous portions of the bands I9. The spacings of the loops 2| on the bands I9 and 20 are substantially equal and preferably less than the maximum permissible thickness of the casing I3 when filled and in its normal configuration with the cushioning material undistorted. The described spacirigs of the loops 2| are such that the tie members Il and I8 limit the flow of the cushioning material I2 when the pillow is in use and permits substantially free flow thereof during manipulation or distortion of the pillow in the manner commonly called iiuffing Obviously, when the casing I3 is filled with cushioning material I2 as described and with the tie members |'I and I8 drawn substantially taut, the pillow will normally tend to retain the configuration shown in cross section in Figs. 2 and 3. The tie members limit the thickness to that shown and the cushioning material tends to hold the tie members relatively taut except when such material is compressed or otherwise distorted by use. Without some means such as the continuous longitudinally movable tie members |'I and 8, the limited amount of cushioning material would not be held by the casing I3 in a compact undistorted bulk, but would tend to flow in the casing and upon manipulation, the easing would be only partially filled. The tie members I1 and I8 being free to move relative to the loops 2|, are self-adjustable to permit easy manipulation of the pillow from undistorted to any distorted position or from one distorted position to another or from a distorted position back to its normal configuration.
Thus, it will be seen that I have provided an article such as a pillow or the like having cushioning material of improved desirable characteristics and novel means for limiting the capacity of a casing containing such cushioning material whereby the pillow is always relatively compactlyi'illed and the resiliency and cushioning qualities thereof are increased.
Having thus described my invention, it will be obvious that various immaterial modifications may be made in the same Without departing from the spirit of the invention; hence I do not Wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
