tumbling and rolling Patented Dec. 4,. 1934 UNITED STATES PATENT OFFICE LAUNDRY BAG Eugene O. Gwaltney, Laurinburg, N. C. Application November 9, 1931,#Serial No. 573,958

This invention relates to dry nets or bags or net for convenience, the invention laundry net. laundry bags or nets to be washed are placed 2 Claims.

laundry bags or laundyeing purposes. For will be described as a More particularly it relates to of the type wherein goods in the bag, the bag pinned up, and the bag and contents subjected to vigorous tumbling in hot, soapy water.

This application has certain features in common with companion application Ser. No. 573,957, led concurrently herewith.

An important object of this invention is to produce a laundry bag or net which is made to last longer than the usual nets of this type now on the market, by virtue of certain weaving' which adds additional strength and resistance to wear without increasing the weight or cost of the bag.

The usual laundry bag out in the lower half of the fact that the top of it in a restricted and closed position,

or net tends to wear the bag. This is due to the bag is pinned to hold,

and this pinning forces the clothes in the bag toward the bottom, causing the lower half of the bag to bulge.

Since this type of bag is friction in the washers, the lower half of these very short while, leaving very little. The bag in such ly worthless and must be discarded,

less waste.

Many attempts have subjected to considerable is not uncommon for bags to wear Iout ina the top portion worn condition is practicalcausing needbeen made in this art to perfect a bag which can be produced at a minimum cost and withstand the harsh treatment of life of the bag may, of

in washing machines. The course, be prolonged by making the bag of heavier yarn, or providing the bag with a. closer mesh.

' These expedients, however, increase the weight and expense of the bag,

and present just this much which must be washed and each laundry operation.

In the patent to Howe ary 9, 1926, reenforcing more weight of yarn handled and dried in 1,572,605, granted' Februbandsare used, but their reenforcing value is nulliiied by the use of the large mesh, necessarily weak, between the reenforcing bands; these lines in Fig. 3 of the patent woul Moreover, the bag of the of large mesh, shown d quickly be ruptured. present invention is woven tubular and seamless and of leno weave, while the Howe bag is woven at and sewed into tubular form and so provided with a seam; Howe does not use a leno weave.

In the patent to Elliott 928,642 of July 20, 1909,

there is no teaching of any in the upper and lower par different construction t of the bag, vwhich is -an important feature of the of leno weave as is applicant's invention, but is woven flatand sewed up to make a bag.

The bag of this invention is made of leno weave, which has the advantage of providing a coarse mesh, the large holes permitting inflow and outflow of the hot, soapy water, but which has the disadvantage of being not very resistant to wear; if a small hole should get started by a break in the yarn, there is a tendency to ravel and run, with consequent rapid spread of the hole.

According to this invention, these diculties are remedied and the life of the laundry net very substantially increased without increasing either its weight or its cost.

The laundry bag of this invention is made seamless and tubular and of leno weave; the lower part of the bag, say about 60%, is provided with strengthening and reenforcing bands running lengthwise and crosswise of the bag, dividing this part of the bag into relatively small rectangular portions, which, in practice, may be squares about four inches on an edge; they could, however, be made larger or smaller, as desired. The longitudinally extending reenforcing bands are preferably of leno weave, of much closer mesh thanl that used throughout the bag, whereas the laterally extending reenforcing bands are preferably of plain weave. The longitudinally extending bands of closely woven leno weave may and preferably do, extend for the entire length of the bag and thus give the top of the bag some degree of reenforcement.

The lower half or lower 60% of the bag is thus \90 reenforced longitudinally and laterally by the bands 3 and 5. These bands divide up the bag into small rectangles; any break, tear or run occurring in one of these small rectanglesis restricted or localized to thatrectangle by the reenforcing bands which define it.

The ratiobetween the lower part of the bag provided with the reenforcing rectangles and the top part of the bag may be approximately as one to one. However, this may be varied within a reasonable range and in the preferred embodiment of the invention about 40% of the bag may be made with only longitudinally extending. bands, while the lower 60% maybe made with both longitudinal and lateral bands. This ratio could be reversed, if desired.

In order further to prolong the life of the bag lt may be provided near its upper or open end with a pinning band of substantial width made of plain weave. While the leno weave may be better for the body of the bag, because of its large mesh. such leno weave isinot as durable against pinning as the plain weave and so the provision of a pinning band of plain weave substantially inn creases the life of the bag. i;

Near the bottom of the bag the leno weave changes into a plain weave, thus forming a friction band; below the friction band there is a single-ply tightlywoven plain weave forming a tabby bottom, the lower edge of which is provided with a heavy overcast seam for preventing raveling. The overcast seam tends to fold back on the bag and rub against it, especiaily if the bag is turned inside out as is oftentimes done. -This Aovercast seam and the leno weave, against which the'overcast seam may bear if it is bent back against the bag.

In a modified form of the invention, in addition to the reenforcing bands above described, the strength of the lower part of the bag may be further enhanced by distribution and selection of weaves which are now to be described. The upper part of the bag, where the wear is relatively light, may be made of coarser `mesh than usual in a bag of corresponding weight and the yarn thus saved may be utilized in making the lower part of the bag where the wear is relatively heavy, of a mesh of closer weave than usual ina bag of corresponding weight, thereby increasing the durability of the lower part of the bag. Coarseness of the mesh inr the upper part of the bag and the finer mesh in the lower part of the bag are eiected through control of the weft or filling. The resulting bag is no heavier and contains no more yarn than a bag of corresponding size and weight yet has a substantially greater life than a bag of corresponding size and weight which is provided with a uniform mesh throughout.

- The ratio between the coarse weave in the` upper part of the bag and the closer weave reenforced by the' iongitudinally and laterally extending bands, is approximately as one to one. This may be varied within a reasonable range and in the preferred embodiment of this modification about 40% of the bag is made of coarse mesh and the lower 60% of closer mesh and reenforcing bands. This could, however, be reversed, and the upper 60% of the bag made of coarse mesh and the lower 40% of closer mesh.

This modification may, of course, be provided with the pinningA band, overcast seam, and friction band as hereinbefore described.

The warp yarns extend longitudinally of the lbag, from one end to the other. That is, any section perpendicular to the longitudinal axis of the bag would show the same number of warp yarns. Different amounts of weft or filling, however, are used at different places lengthwise of the bag.

The invention will be further described in connection with the accompanying drawing showing in more detail the preferred embodiments thereof.

In the drawing, y

Fig. 1 is a front view, partly broken away of a laundry bag made according to this invention;

Fig. 2 is an enlarged cross section of the bottom of the bag on the'line 2-2 of Fig. 1;

Fig. 3 is a front view of a modication showing the several weaves in addition to the reenforcing bands; and n Fig. 4 is a view of a modification.

Referring now to the drawing, in which similar reference characters indicate similar parts, the laundry bag illustrated in Fig. 1 is of the leno weave type, made tubular and seamless, the Warp extending longitudinally of the bag, that is from top to bottom or lengthwise thereof. AThe greater part of the bag is of leno weave of substantially the same texture throughout. 'Ihe warp threads of this weave are indicated at 1 while the weft or filling threads are indicated at 2. Extending longitudinally of the bag is a series of closely woven reenforcing bands of leno weave, designated at 3. In the lowerportion 4 of the bag 1 is a series of laterally extending reenforcingbands 5. These bands are of plain weave and are spaced from that the longitudinal bands are placed. The

small squares or rectangles 3 where the bands cross are of tightly woven plain weave. The lower half of the bag is thus providedA with a series of relatively small sections 4 of leno weave. cIt is thus readily seen, that in addition to generally reenforcing the lower part of the bag, these bands serve to localize any runs. tears, rips, etc. Any break occurring in the coarse leno weave forming the bottom portion of the bag may be repaired without affecting the rest of the bag.

The reenforcing bands may occupy approximately the lower half of the bag, or according to the present preferredr embodiment of the invention approximately the lower 60% of the bag is reenforced by the two kinds of bands, while the rest or upper part of the bag is reenforced by the longitudinally extending` bands of closely woven leno weave.

By making the entire body of the bag of a leno weave, not in itself rugged enough to withstand much harsh treatment, and reenforcing it by the longitudinal, lateral reenforcing bands, the strength, durability and life of the bag is substantially increased.

In order further to strengthen the bag, there is provided around its upper or open end a pinning band 6 made of plain weave, the plain weave being preferable because it is more resistant to pulling out than is leno weave.

.As described in my copending application ied concurrently herewith, the extreme bottom edge of the bag is provided with a heavy overcast seam 7, for preventing raveling. Thisovercastseam tends, when the bag is in use, to bend around and rub against the body of the bag, especially if the bag is turned inside out as is oftentimes done. 1n order to prevent such wear, there is provided, near the bottom of the bag, a friction band 8 of plain weave. The leno weave 12 in the lower part of the bag at about the line 9, changes into a plain weave 8, forming this friction, band. At about the line 10 the two lower edges of the friction band 8 are tightly woven together tc make a-thick relatively still one-ply tabby bottom 11, the lower edge of which terminates, as has been described, in the overcast seam 'I for. preventing raveling. This tabby bottom is of about the texture of a very heavy duck. With such a tabby bottom, there is no need to turn up the bottomof the bag and close it by stitching, as in the patent to Sitton 1,682,198, of August 28, 1928.

In use, the tabby bottom 11 tends to swing friction band 8, which is strong enough to resist such friction. The seam 'I thus does not rub against the leno weave 12, which is not so strong and not so able to resist this friction.

Referring now to Fig. 3, the bag there illustrated is tubular and seamless and of leno weave, and has longitudinally extending reenforcing bands 22 of close leno weave extending for the entire length of the bag; the lower half or preferably the lower 60% of the bag is provided with laterally extending bands 25, dividing the lower part of the bag up into small squares or rectangles, as in Fig. l. In addition, however, the upper half or upper 40% of the bag, is made of a coarser leno weave than usual in a bag of corresponding size and weight, and the yarn thereby saved is built into the lower half or lower 60% of the bag, thereby making this lower part of the bag stronger in that portion thereof where the strength is most needed, that is, where there is most friction.4

This change of mesh is effected by the use of additional filling or weft in the .lower part of the bag. The warp yarns extend for the entire length of the bag. This form of the invention may be provided with a pinning band 6, friction band 8, tabby bottom 11 and overcast seam?, as in Fig. 1.

In the modification shown in Fig. 4, the bag or net 30 is. for the most part, of leno weave, and like the other forms, is tubular and seamless. The same mesh of leno could be used throughout, or, as described in connection with Fig. 3, the lower part could be of closer mesh than the upper part of the net. In this form, a plurality of reenforcing bands 32 of closely woven leno extend longitudinally of the bag, while a plurality of reenforcing bands of closely woven plain weave 34 extend laterally of the bag, forming small rectangles 36 bordered by reenforcing bands, thereby localizing any runs, breaks or tears that might occur in any rectangle. 'Ihe intei-sections 33 of the bands are of very tightly woven plain weave.

The mouth of the net may be provided with a narrow band 38 of plain weave, the upper edge of which is provided with an overcast seam 40. This band 38 is particularly useful in preventing raveling, especially during manufacture. This band 38 maybe made wide enough, as in Figs. 1 and 3, to provide a pinning band corresponding to the band 6.

The 4several bags illustrated, by the reason of construction and particular weaving of the yarns, as has been described, have a durability and life substantially greater than the ordinary type of laundry bags yet with little increase in amount of material used and consequent cost. The bags may be used for dyeing and other uses and the claims are to be construed accordingly. While the preferred embodiments of the invention haveV been described in some detail, it should be understood that the invention is not to be limited to the exact details and proportions shown, but may be carried out in other ways as falling within the scope of the appended claims.

I claim as my invention:
