Application filed April 12,

type of such improved construction that the drawstring which closes the open end of the bag is a woven strand of the material of which the bag is formed.

Prior to this invention, woven bags of the general type to which this invention relates were provided with drawstrings or ties, and various methods were employed to slidingly retain the drawstrings or ties in position so that they might perform their function of drawing the open ends of the bags together to close said open ends. For instance, it has been common practice to provide bags with inturned hems at the open ends thereof for retaining the drawstrings or ties in place, and

' also rows of stitches have been provided which were intended to prevent the drawstrings from slipping from the necks of the bags.

.None of the arrangements for. retaining ties or drawstrings in place with which I am familiar functioned in an entirely satisfactory manner, and I have, therefore, devised the arrangement disclosed herein which, briefly stated, involves providing the bag with a drawstring which constitutes a woven strand of thematerial of which the bag is formed. The drawstring, which preferably is a warp thread, would in most cases be somewhat stronger and probably heavier than the other threads of which the woven fabric would be formed, or if not heavier said drawstring would be distinguishable from the other threads by being made from different material, or by being of 'a different color. A drawstring which constitutes a woven element of the open mesh material of the bag is slidable freely with respect to the bag material, and therefore may be drawn so as to tightly close the open end of the bag to prevent escape of the contents of said bag.-

Fig, 1 illustrates a part of a web of woven material from which one of my improved G HEISSUED 1930. Serial No. 443,669.

bags is to be made, portions of said material being broken away to' conserve space.

Fig. 2 is' a view of a bag made in accord-. ance with this invention, in this View, also, "portionsof the bag materialbeing broken, away to conserve space.

Fig. 3 is an enlarged, fragmentary section on line 3+3 of Fig. 2.

Fig. 4 is a view similar to Fig. 2 but showing another form of the invention.

Fig. 5 is an enlarged, fragmentary section on line 5-5 of Fig. 4.

In the drawing, wherein are shown for the purpose of illustration, merely, two embodirnents of the invention, A designates the ma terial of which the bag is formed, said material being comprised of warp threads (1 and Woof threads 6. The threads a and b of "the material A are woven in the usual manner, so that the mesh of the material is quite open, and said material A is preferably provided with a selvage B, the material A being so cut and folded that the selvage B is located at the upper, open end of the finished bag. The material A shown in Fig. 1 has a selvage at one edge only thereof, because the illustrated material constitutes a part only of the width of the entire web of material. In some cases where larger bags are being made the bag material will be provided with oppositely disposed selvage edges. Also, when two bags are made from a single width of material, this width of material will be provided with opposed selvagenedges, and a pair of drawstrings will be woven into the material, one thereof adjacent to each selvage of the mat-erial, and the width of material will be cut and a bag provided with a woven-in drawstring will be made from each section of the severed from the other threads of which the material A is formed. For instance, the drawstring may be heavier than the other threads, as in Fig. 2, or it may be made of a diflerent material, or colored a distinguishing color. Likewise, the drawstring may, if desired, be of a different shape, as in the case of the more oi less flat drawstring C illustrated in Fig. 4, or, a plurality of associated and closely grouped elements may be employed to provide the drawstring.

In forming my improved bag from a portion of a web of material suitable for making one bag, said web of material is folded on its center line, the fold forming one side of the bag and with the selvage B disposed at the top of the bag. The folded web is then sewed with a row of stitches D which extend from top to bottom, thus joining the two ends of the web to form the other side of the bag, and the stitches D are extended across the lower end to close the bottom of the bag. The particular type of seam illustrated in the drawing does not require that the bag be turned, but if other types of seams are employed the bag would be turned to turn in the sewed edges of the bag material. i

In producing the form of the bag illustrated in Figs. 2 and 3, the ends C of the drawstring are pulled free of the side seam E before the sewing operation is performed, and in this event the drawstring will appear as illustrated most clearly in Fig. 3. However, if desired, the drawstring may be sewed into the side seam E of the bag, as shown in Figs. 3 and 5, wherein C designates the drawstring and A the material of which the bag is formed, and after the stitches D. have been placed .in the bag the drawstring C may be pulled or out free of the seam. Also, if preferred, the ends of the drawstring may be permitted to remain stitched into the side seam of the bag, as shown in- Figs. 4 and 5, and the mouth of the bag may be closed by pulling the drawstring from the folded side of the bag.

When the drawstring is close to the selvage B of the bag the usual method of closing the bag will be to draw up the drawstring and tie the opposite ends together. If desired, however, the drawstring may be arranged a greater distance below the selvage B, and after the mouth of the bag has been drawn to a closed condition the ends of the drawstring may be wrapped several times around the puckered mouth of the bag. The latter would be the stronger closure because all of the threads I) of the bag material would be engaged by the drawstring, whereas in the case of the first method only half of said threads would be so engaged.

An important advantage in favor of the present invention results from the fact that the material and time necessary in providing the bags with hems at the open ends, as in some cases heretofore, is saved. Also, as the bag material of my improved bag is of quite open mesh, the open ends of the bag could not be stitched to close said open ends with success, as the stitches would pull out. My improved arrangement provides an ideal closure for such open mesh material. Likewise, when my improved structure is employed .theclosure strain on the material at the mouth of the bag is substantially uniform, whereby a positive closure is obtained.

I claim:

1. A bag formed of open mesh, woven fabric and a drawstring which constitute a woven strand of said fabric, said drawstring being interwoven with substantially all of the strands of the fabric which extend transversely with respect thereto.

2. A bag formed of open mesh, plain woven strands of material and a' drawstring which constitutes a woven strand of the bagforming material, said drawstring being interwoven with substantially all of the strands of material extended transversely with respect thereto.

3. A bag formed ofopen mesh, plain woven strands of fabric and a drawstring which constitutes a woven strand of bag-forming fabric, said drawstring being interwoven with substantially all of the strands of fabric extended transversely with respect thereto, and being distinguishable from the other strands of the bag-forming fabric. i In testimony that I claim the foregoing I hereunto aflix my signature.

HENRY H. ALLEN.
