Patented Apr. 17, 1962 3,029,816 GEOMETRICAL DIAPER Josette M. Neils, 5400 N. 53rd St., Milwaukee, Wis. Filed Apr. 8, 1958, Ser. No. 727,199 2 Claims. (Cl. 128-284) This invention relates to a geometrical diaper.

Objects of this invention are to provide a novel, simple, and effective diaper for infants wear.

Further objects of this invention are to provide an infants' diaper made of double-layer cotton gauze fabric, permanently folded and stitched into a collapsible tubular bias form.

An embodiment of the invention is shown in the accompanying drawings, in which:

FIGURE 1 shows two equally surfaced squares of fabric each diagonally right-angled.

FIGURE 2 shows both squares similarly angled, rolled into a bias fold.

FEGURE 3 shows bias fold in its tubular bias form.

FIGURE 4 shows collapsed tubular 'bias form drawn to an enlarged scale.

FIGURE 5 shows the geometrical diaper fastened on one side.

Referring to the drawings, it will be seen in FIGURE 1 that the device comprises two squares of fabric of equal dimensions, each centered by diagonal true on the bias grain lines 1 and 2. Center line 1 is split in three by folding lines 3-3, thus obtaining two perpendicularly opposite triangles e -4 which consequently, adopt foldinglines 3-3 as their respective bases. Dashes show future position of triangles 4-4 and 44.

it will be seen in FIGURE 2 that the triangles 44 in each square have been folded over and overlap each other across center-line l.

Opposite ends 5-5 entirely superimpose each other, and are stitched to join both squares together across one third of their respective center-line 2. Thus combined, the prefolded squares assume the appearance of a rolled bias fold. Flat-lockstitch or other purposely similar stitches 7 are used to stitch edges of triangles 4-4 and 4-4 to underside of bias-fold and throughout entire construction of geometrical diaper.

It will be seen in FIGURE 3 that ends 66 have been joined together similar to ends 55 thus giving the bias fold the shape of a tubular-bias form.

The geometrical diaper is now completed.

It is to be noted in FIGURE 4, that although the collapsed tubular-bias form has the general outward shape of a commonly folded "straight-of-the-fabric diaper, the four and six layers of double gauze fabric composing the geometrical diaper are utilized entirely on the true bias grain.

Object of drawing in FIGURE 5 is to show one side of the geometrical diaper fastened with the help of a safety pin or other suitable fastener.

From the foregoing it should be readily apparent to those skilled in the art that the geometrical diaper above described is preferably made from two equally surfaced squares of double layer cotton gauze fabric, which is folded and stitched together in such a fashion as to become a tubular bias form. This tubular bias form does not allow any straight on the grain or so-called straight of the fabric seams along the sides of any of the edges of the diaper, and this eliminates possible skin irritation and the stretching action of the bias allows freedom of movement while still fitting snugly. The diamond shaped stitching materially strengthens this diaper so that While it may stretch, it will not lose its original form and above all the particular endless tubular shape of my diaper means that the same can be rotated or moved, so that its wear surface can be alternated throughout the entire inner and outer surfaces of the diaper, as it is obvious that the diaper can readily be turned so that the inner surface can become the outer surface. This is a very important feature of my diaper in that the entire exposed surface of the diaper can be utilized as a wear surface at one time or another, thus giving a diaper which will out last present known types of diapers by a considerable length of time. This tubular or cylindrical shape or form and endless strip type of diaper gives a thickness which comprises four, and for the most part six layers of cotton gauze fabric for moisture absorbing efiiciency, and at the same time this diaper allows air to circulate freely throughout all surfaces when it is hung up for drying after being washed.

1 claim:

1. A woven diaper comprising a prefolded endless strip including, two squares of material of substantially equal dimensions overlapped and joined at respective corners, the adjacent opposite corners of each square of material being folded inwardly, overlapped and joined, and the extreme opposite corner of one square of material being overlapped and joined to the extreme opposite corner of said other square of material.

2. A Woven diaper as set forth in claim 1, wherein the respective squares of material and overlapped corners are joined by stitching of diamond configuration following generally the folded contours of the overlapped material.
