BIAS CLOTH BAG.
SPECIFICATION forming part of Letters Patent No. 408,858, dated August 13, 1889.
Application filed December 29, 1888. Serial No. 294,956. (ModeL) To all whom it may concern.-
Be it known that I, JOSEPH L. SEYMOUR, a citizen of the United States, residing in Brooklyn, Kings county, New York, have invented certain Improvements in Bags, of which the following is a specification.
My invention relates, mainly, to bags made from textile materials; and the object is to produce a stronger and better bag in some respects than those in common use, and to produce such a bag at a low price.
Bags made from textile or woven fabrics in the ordinary manner have the warp and weft arranged parallel with the sides and ends of the bag-that is to say, one set of the threads of the fabric extends lengthwise of the bag and the other set extends around the bag, or at right angles with the first-named set. The effect of this arrangement of the threads is to put the strain on the threads in the direction of their length when the bag is full or charged, and to a great extent each set of threads must bear the strain upon it independently. In such a bag, also, the raw,edge at the mouth of the bag must be hemmed or bound to prevent it from raveling out.
My invention obviates the above difficulties by so arranging the fabric in making the bag that the warp and weft threads will be bias, or stand obliquely to the top, bottom, and sides of the bag. Thus the lateral and longitudinal strains on the bag will both be oblique to the axes of the Warp and weft threads of the fabric, whereby both sets of the threads partake of the strains, and thus the fabric presents an elastic and yielding resistance to said strains. This permits one to use a less expensive material for the bag than in the case where the strains are parallel with the threads, in which case there is little elasticity and stronger material must be used. In this bag, also, the raw edge about the mouth of the bag is cut bias, and consequently does not ravel, and will not require to be hemmed or bound.
Owing to its peculiar construction the seams of this bag will be oblique with or bias to the sides and ends of the bag, and usually the selvages will be joined by stitching or otherwise, thus forming the strongest possible seam. Seams arranged bias to the sides of this instance the second from the left.
the bag or spirally with its longitudinal axis also impart great elasticity and strength to the bag.
The bottom of the bag may be seamlessthat is, formed by a fold in the fabricor it may in one form of the bag be closed by a seam; or, where the bag is madefrom a tubupart only of its extent. Fig. 2 is a'view of a bag formed from a section of such blank-in Fig. 3 is a fragmentary perspective view illustrating the manner of constructing one form of seam which closes the bottom of the bag; and Fig. 3 represents two cross-sections on line 3 3 in Fig. 3, showing how the bottom is folded in making the seam. Fig. 4 shows another form of the bag with a seamless bottom, and Fig. 4 is a view, on a smaller scale, illustrating the manner of cutting the bag illustrated in Fig. 4 from the piece. Figs. 5, 5, and 5 illustrate another form of a seamless-bottom bag made according to my invention. Fig. 5 shows the bag-blank; Fig. 5, the blank folded to form the seamless bot tom, and Fig. 5 the finished bag. Fig. 6 shows the bag cut from the tube seen in Fig. 1 and tied and closed at the bottom 6.-
In making up my bag in the manner illustrated in Figs. 1, 2, 3, and 3, I take astrip of woven fabric-as m uslin-with selvage edges, and stitch the edges together in a manner to form a tube with a spiral seam, as shown in Fig. l. The obliquity of the seam will preferably be about forty-five degrees with'the axis of the bag blank or tube, but will vary, of course, according to the Width of the strip of material and the width or circumference of the bag to be made. Such a blank can be readily stitched on a sewing-machine, owing to the flexibility of the material, and the length of the blank will only be limited by the length of the strip of material. Indeed, by cross-seaming the length of the blank may be extended indefinitely.
In the drawings, a represents the spiral or oblique seam.
In forming the bags from the bag-blank the tube is flattened, as shown in Fig. l, and out across transversely, as represented by the dotted lines at, each section thus cut from the tube having the proper length for a bag.
The bag 13 represented in Fig. 2 is formed from such a section cut from a tubular bagblank. At its open end or mouth Z) this bag is cut bias of the material, and requires no hemming or binding. At its bottom I) the bag is closed by a seam. In Figs. 3 and 3 the manner in which this closing or bottom seam is formed is illustrated. The views show the marginal flap c of one ply of the bag turned in. This forms tucks or folds e at the ends of the seam at the two bottom corners of the bag. The marginal flap c of the other ply of the bag is now folded over on the outer face of the first or opposite ply and secured by stitching through and through, as seen in Fig. 2, or otherwise. This closing of the bottom of the bag provides four thicknesses of the material across the bottom and six thicknesses at the corner tucks 1.1. These tucks etlectuall y close the corners against leakage.
Such a bag as that above described may be made with very little labor and from lowgrade goods in view of the peculiar construction imparting extra strength.
In Fig. 4 I have shown some of the importaut features of my invention embodied in a bag of another construction. In constructing this bag the blanks are of triangular form, as shown by the lines 1, 2, and 3 in Fig. it, which represent the outline. The size of the bag is represented by the rectangle embraced by the dotted lines in Fig. at". The tinting or ruling in the several views indicate the direction of the warp and weft in the material of which the bag is made.
In constructing the bag represented in Fig. 4E from this triangular blank two bias or oblique seams (Z (Z are employed and the seam less bottom is formed by a fold in the material.
The bag illustrated in Figs. 5, 5, and 5" has a seamless bottom formed by folding the blank illustrated in Fig. 5 along the line 4,
when the blank will assume the form seen in Fig. 5. The blank is now folded along the lines 5 5, and the edges thus brought together are united to form the two oblique seams (I, which close the bag at its sides.
I contemplate furnishing my bags to the trade without closing the bottom, when the user may close both the bottom and month by gathering and tying with a string; or I may close the bottom by tying before the bags are sold. Fig. 6 represents a bag with its bottom closed in this manner constructed according to my invention.
My invention is adapted to bags of all sizes and adapted for all purposes where bags are required, and the bags may be made from fabrics of various kinds cut and secured as described.
Having thus described my invention, I claim 1. As an improved article of manufacture, a fiat rectangular bag made from woven fabric and having the closing seams arranged oblique to the axis of the bag.
2. As an improved article of manufacture, a fiat rectangular bag made from woven f abric and having the warp and weft of the fabric arranged bias to the axis of the bag.
As an improved article of manufacture, a Hat rectangular bag made from woven fabric and having the seams arranged along the selvages of the fabric and oblique to the axis of the bag.
4. As an improved article of manufacture, a flat, seamed, rectangular bag made from woven. fabric and having a raw bias edge about the mouth of the bag.
As an improved article of manufacture, a bag made from textile material having a seamless bottom formed by a fold of the fabric extending bias of the material, and having its sides closed by seams oblique to the longitudinal axis of the bag.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
