SAMUEL BERNSTEIN, OF MOUNT VERNON, NEW YORK.

- WOVEN BAG.

SPECIFICATION forming part of Letters Patent No. 240,645, dated April 26, 1881.

` Application ined June 2e, 1879.

To all whom it may concern:

Be it known that I, SAMUEL BERNs'rEIN, of `Mount Vernon, in the county of Westchester and State of New York, have invented a new and useful Improvement in Voven Bags, which improvement is fully set forth in the following specication, reference being had to the accompanying drawings, in which- Figure 1 shows my bag partly in side view and partly in section. Fig. 2 illustrates the man ner of weaving a number of bags. Fig. 3 is a section on the line .e w, Fig. 2. Fig. Lis Va section on the line y y, Fig. 2. Fig. 5 shows the arrangement ofthe pockets containing shirrin g-strin gs.

Similar letters indicate corresponding parts.

My invention relates to bags or pouches for holding tobacco, coin, and other articles which are carried on the person, and is applicable also to bags orpouches of large size for holding any kind of merchandise.

'It consists in a bag made complete and provided with shirring threads or strings in the process of weaving, the bags being woven consecutively, so that it is only necessary to cut them apart as they come from the loom, when they are ready for use, the shirring threads or strings being tied at their severed ends. The fabric is so woven that the bags are arranged side by side, each bag occupying the whole width of the fabric. One edge of the fabric forms the bottoms of the bags, the mouths or open ends of the bags being at the opposite edge of the fabric. The fabric is woven double for that 4length which is required for the width of the bag, and then all the warp-threads are woven together into a single thickness of cloth for a little space, so as to form a web, which separates the adjoining bags, and then the weaving proceeds as before, to form a fabric of two thicknesses, closed at one edge of the fabric to form the bottom of the bag, and open at the other edge of the fabric to form the mouth of the bag, as explained before. The shirring threads or strings form parts or" the warp on that side of the fabric where the mouths of the bags are formed.

In the drawings the letter A designates a bag constructed according to my invention, and composed of a fabric which is double, or, in

other words, is made with two thicknesses, b b,

between the sides c of the bag, and between g the bottom e and the mouth d.

The lettersf designate the shirring threads or strin gs, which are interlaced in the process ofthe weaving with the shuttle-thread near the mouth of the bag, and in each thickness of the fabric. There are four shirring threads or strings, two of them being interwoven with each thickness of the fabric, inthe manner indicated in the drawings. One of theshirring threads or strings which are interlaced with facturer, only tWo shirring-strin gs may be combined with the warp.

`Observing Fig. 2, which represents a piece of bag-fabric as the same is produced by my method on the loom, the letters A A designate the portions of the fabric which constitute two bags, and the letters c c designate webs which unite adjoining bags to each other when the fabric is woven.

I begin the production of the fabric by weaving all the warp-threads together into a single thickness across the whole fabric, as at c c, thereby forming the edge of a bag, and then divide the warp-threads so as to form therefrom two sets of warps extending across the width of the loom. This arrangement of the warp-threads is, of course, provided for before the weaving commences, in the manner well known to weavers, for weaving two thicknesses of cloth independently of each other, and throwing the sa-me warps together at the desired intervals, so as to form a single thickness from the united warps for the desired extent in the weaving. While the whole body of the warps is being operated so as to form two independent bodies of warps, the slied for the passage of the shuttle is formed in each of said bodies successively, and the shuttle is passed, observing Figs. 2 and 3, from the right side of the fabric, marked d, across through one shed-say, for example, the lowemedfto the left side, marked c, and in returning IOO -warp threads.

to the right side is made to pass through the shed-say the upper shedof the remaining The shuttle is next caused to pass again from right to left through another upper shed made from the said remaining warp-threads, and when it reaches the side marked e it returns to the right side through the lower shed, and so on, two successive picks being woven with each division of the warp alternately, until enough of the double fabric has been woven to form the desired width for one bag or pouch, when the whole body of Warps is operated together to form a single thickness across the fabric, as at a, thereby producing a Web which intervenes between the last portion of the double fabric woven and the neXt portion of double fabric.

The weaving may, of course, be interrupted when a second web, c, of sufficient width has been woven, thus completing one bag; but I- contemplate producing the bags or pouches with the intervening webs in succession, asindicated in the drawings, and severing the webs across the center of their width, so as to leave a safe or strong edge on each side of the bags.

The shirring strings or threads f may, if it is desired that they should be longer than the width of the bag, be drawn out from oft' the warp-spools so as to produce sufficient slack thread at each web, c, to give the length of shirring string 0r thread desired. rlhe shirring strings or threads, as well as the other portions of the warp, are controlled by the jacquard of the loom,or other devices suitable for the purpose, in the manner well known to Weavers familiar with Jacquard and other looms. The shirring strings or threads are so controlled by the jacquard or other apparatus used for that purpose that one-half of them is thrown in one body and the other half into the other of the divided warp during the time that the fabric is being woven of two thicknesses.

After a bag is severed .from the fabric it is turned inside out, thereby bringing the edges ofthe web c in the inside of the bag, as indicated in Fig. l.

Ihe bag thus produced is complete without sewing, and without applying any other fastening device than that obtained by means of the shirring strings or threads.

I do not lay claim to the inventions described in the several Letters Patent No. 6,566, granted to W. B. Oarlock; No. 24,691, granted to Baare vand Garelly, or No. 160,453, granted A. M. Miner, but

ing part of the warp and woven in the fabric,

the warp ofthe fabric ruiming crosswise, or from side to side of the bag, and the weft or shuttle threads lengthwise thereof, substantially as described.

In testimony-that I claim theforegoing I have hereunto set my hand and seal this 25th day of June, 1879.

SAML. BERNSTEIN.
