April 24, 1956 P. E. MAUTZ CUSHIONS AND CUSHIONING MATERIAL Filed July 17, 1952 Jnz/Efifaa. Paul E- [775L272 United States Patent CUSHIONS AND CUSHIONING MATERIAL Paul E. -Mautz, Newark, Ohio, assignor to'Owens-Corning Fiberglas Corporation, a corporation of Delaware Application July 17, 1952, Serial No. 299,309
6 Claims. .(Cl. ii -361) This invention relates to cushion or padding construction particularly of the, type used for mattresses, seat cushions and other upholstered products.
1n the past, fibrous glass material hasbeen used in the construction of pillows, cushions, and padding. The material was extremely useful where its non-allergenic characteristics were -of primary consideration. For general use however, improved wearing properties were required. Torachieve this and, .militateagainst any attrition effect, fibrous glass has been coated-with lubricating orbinding materials and impregnants, for instance rubber latexand the like.
It was found in attempting to increase the 'life of the fibrous glass cushioning material that coarse'fibers were short-lived and by using afiner and finerfiber, the life of the material was extended. However, it was'found that the utilization of fibers suffieiently'fineto decrease'brittle-' ness and self attrition resulted in cushioning that Was too fiulfy, soft and compressible.
.Anobject of this invention is to obviate the above disadvantages :and produce a fibrous glass cushion or padding material which is highly durable and satisfactory for the purpose. I
Another object is to produce a fibrous glass cushion or padding which can be readilyiancl economically manufactured on a commercial basis. a.
A further object is to produce a process for manufacturing cushions and the like of a fibrous glass material which militates against the breaking down of the fibers whenin use.
.yQther objects and advantages wihchereinafter appear and for the purposes of illustratiornbut not of limitation, an embodiment of theinvention is shown in the accompanying drawingin which: 1
Figure 1 is a fragmentary sectional view in perspective of a cushion showing the invention; and
Figure 2 is an enlarged fragmentary sectional view showing in exaggerated fashion the bulged portions of the pads intermediate the rows of stitches.
The present invention is based on the discovery that if the fibrous glass is built up in a plurality of laminates and each lamination is individually quilted, the attrition effect is substantially eliminated and the life of the cushion or padding material is prolonged to such an extent that a seat cushion or pad made from the material is highly practicable in addition to having the other attributes hereinbelow set forth.
The illustrated embodiment comprises a cushion made up of a plurality of superposed pads A, B, and C of fibrous glass. For best results, the fibers are of a diameter of the order of fifteen hundred thousandths of an inch, and should not be less than ten nor more than twenty hundred thousandths of an inch.
Each pad comprises a plurality of laminates or mats 12 which are composed of a mass of glass fibers. The fibers, generally indicated at F, are arranged in generally helterskelter relation to each other and are bonded together into the mat 12.
The separate mats are preferably made by depositing by means of a blast of air or gas, long, fine glass fibers onto a suitablecollecting surface. The fin'e fibers double back and forth on the surface to be haphazardly arranged in horizontal planes but, because of their length,- they are predominately parallel with the collecting surface and with the major faces of the-mat. The fibers of the mat 12 are bonded together by means of a suitable adhesive suchasa resin, for example phenol or urea formaldehyde, and apparently because of the small diameters of the fibers the mat may be of very low density, ordinarily weighing approximately one half to one pound .per' cubic foot.- The rectangular or other desired shapes to correspond to the shape of the cushion arecut-from the mat. Themats 12. are then superposed on eachother to build up a laminated pad of three to four inches in thickness.
The built-up layer of superposedrn'ats or the-pad is then enclosed between sheets 14 of muslin or similar fabric or other flexible and preferably porous sheetmateria'l. The pad is then quilted by stitches extending across or trans-- versely of the fibers. As shown, a line of quilting stitches 16 compacts the mass and thereby increases its density'to approximately'three to five pounds preferably four pounds, per cubic foot measuredat the locationo'f the stitch pass-' ing through the pad. The thickness of the pad is preferably reduced to about oneinch measured at the points where the stitches 16 extend through the pad. Other forms of quilting means may be used to advantage, such for example as a line cf tacking'stitches or other devices which are effective in achieving the desired compacting action. I
The number of pads employed depends'upon thethickness required in the mattress or cushion, ordinarily three,
four,,or up to six or more ofthepa'dsbeirrg superposed to build up into acushion of about three =tc six inches-thick. It has been found advantageous to arrange the pads in such mariner that the rows of quiltin'g stitches 16 of one pad are disposed directly over the row'o'f the pad eer e-w. Stacks of three to sixpads ordinarilya-re adequate.
The quilted'pads prior to being superposed mayha-ve-au adhesive vor friction-increasing coating applied to the meeting faces of the muslin ori'otherco'vering onthepads' to militate against undue lateral shifting of the'la'yers with respect to each otherduring the nseof thec'ushion.
The. assemblage is then inserted into 0r otherwise enclosed within the usual upholstery covering Z't'lafter first beiugencase'din cotton rbatting -ls or the-like. the
case of-Ja mattress, .it may be enclosedin an'enve'lope of ordinary ticking. Upholstery fasteners 24 may be employed for aiding in holding the structure together.
In large measure the practicability of the cushion depends on the combination of the plurality of mats used in making up a pad, the plurality of pads used in making up a cushion, and the quilting procedure. This combination has been found to be critical with respect to the Wearing properties possessed by the finished product. It has been found that where the rows of stitches or the stitches in the rows or both are spaced substantially more than two inches from each other e. g., three or four inches, the finished cushion is inclined to be too springy and soft. On the other hand when the row of stitches or the stitches in the rows are substantially closer than two inches e. g., one inch apart, the cushion becomes too hard and unyielding.
The desired cushioning effect obtained with the stack of pads when the stitches or rows of stitches are on two inch centers, is apparently due to the fact that the bulges between the stitches form points of contact between the superposed pads. This is shown in exaggerated fashion in Figure 2. The density of the fibrous glass at the bulges defines the feel of the cushion or mattress particularly when lightly loaded.
From the foregoing it will be manifest that a cushion or padding material which is highly durable and practical has been produced. The products described find many fields of usefulness due to their resilience, light weight, resistance to mildew and rod, and durability. The method described for the production of the cushion material is simple and economical.
I claim:
1. An intermediate article of manufacture to be used in the making of cushions comprising a pad of glass fibers of the order of 0.00015 of an inch, the pad being made up of a plurality of mats of fibers interbonded in haphazard relation, the fibers of all the mats being of the same diameter and the same kind and the mats being all of the same density, and a plurality of equispaced rows of quilting stitches in the order of two inches apart extending through the pad compressing the mats to such an extent that the density of the mats is increased to a predetermined value several times its original value.
