WOVEN SEAM LESS BAG.

SPECIFICATION forming part of Letters Patent No. 415,150, dated November 12, 1889.

Application filed May 31, 1889. Serial No. 312,829. (No specimens.)

To all whom, it may concern:

Be it known that I, ABRAM D. EMERY, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Woven Seamless Bags, of which the following is a full description.

My invention relates to woven seamless bags composed of a set of chain-threads and two separate weft-threads, (each occupying a half of each pick.) The chain-threads pass lengthwise of the bag over and under the two weft-threads. The closed ends of the bags are formed by passing the weft-threads by each other at both sides into succeeding picks in the manner described in application Serial No. 265,639, filed by me February 28,1888, (Case 1.) The bottom is formed by interlacin g the chain-threads of the two halves of the set around the two weft-threads. The mouth of the bag is a raw edge formed by cutting across the chain -threads. The bags are formed in an endless fabric, as described in an application filed July 22, 1889, Serial No. 318,250, (Case 21.) The weft-threads make continuous passages around the bag in opposite direct-ions, crossing each other at the two ends of the bag alternately, where they are bound together. The succeeding picks on either side of the bag are always formed of the opposite weft-thread. This holds good for either side, whether in the separated portions or that in which the two sides are interlaced to form the bottom.

In the accompanying drawings, forming a part of this specification, like letters and figures refer to like parts in the several views.

Figure 1 is a plan View of the fabric, with the several threads separated to show the formation as well as the position of the chainthreads in the portion in which the two sides are bound together. Fig. 2 is an edge View of the fabric, taken on the side E, showing the mouth of the bag and the position of .the weft-threads at the edges in binding the two halves together, and also showing the cross formed between the two outer chain-threads at each side. Fig. 3 is a vertical cross-section of the plan View on the line A B, and looking toward the side D. The black threads are the shaded threads and the cross-section threads are the plain weft-threads, as shown in plan view, Fig. 1. Fig. 4 is a vertical crosssection of the fabric on the line A B of Fig. 1, looking toward the side C, with the threads represented as in Fig. 3.

In Figs. 3 and at will be seen the position of the chain-threads in the two halves, as well as in the interlaced portion where the two halves are bound together, and also the position of the weft-threads in the two halves. To better distinguish the weft threads, one is shown shaded and represented by the numeral 5, the other is shown plain and is rep resented by the numeral 6. The chain-threads are designated by the

numerals

1, 2, 3, and 4, threads 1 and 2 being the chain-threads forming the side F, and chain-

threads

3 and 4 those forming the side G. These threads pass to opposite sides, respectively, in the portion bound together, as will be seen upon examining the lower part of Figs. 3 and 4, where the thread 1 will be seen on the outside of side F and thread 3 on the outside of side G. At the next pick thread 2 is on the side G and thread 4 on the side F, and so 011 throughout the fabric. It will be seen that at the point where threads 1 and 3 are on the outside 2 and 4 are between the weft-threads forming the fabric, and that where 2 and 4. are outside 1 and 3 are between the said weftthreads. It will also be seen that the chainthreads 1, 2, 3, and efollow each other in regular order in their positions in the fabric and form on both sides a regular four-leaf twill in the part in which the sides are bound together to form the bottom. The weft-threads 5 and 6, each occupying a half of each pick, as shown at each succeeding pick are transferred to the opposite sides of the fabric, thus crossing each other at each edge and binding the two halves together at each end.

The term pick as used in this specification signifies a complete layer of weft around the bag, composed of one weft-thread on one side of the bag and the other weft-thread on the other side of the bag. These two weftthreads are laid at one operation in the weaving by passing two shuttles simultaneously through a double shedding, as explained in Case 21, above referred to, and constitute a single pick of fabric, each weft-thread occupying a half of the same. The position of the weft-threads with reference to the two sides alternates at each pick. In a given side the threads follow each other, first shaded, then plain at all. times, and the corresponding part of the pick on the opposite side is formed by the opposite weft-thread. At the mouth of the bag the threads are not bound together, but form a raw 'or frayed edge, which maybe sewed to prevent the same fraying out or not, as desired.

The bag herein described resembles the fabric which is the subject of application No. 265,581, filed by me February 28, 1888, (Case 2,) in the respect that each pick is oc .cupied by two weft-threads which are transferred into opposite halves of the bag or fabric from one pick into a succeeding pick. In that case only the three sides were closed in the process of weaving, while in the present case the fourth side is also closed by transferring the weft-threads at each pick instead of at each second' pick, as in (Jase 2, thus forming an endless tube in place of a fabric which may be opened out flat.

What I claim is 1. A seamless bag composed of a set of chain-threads and two weft-threads, each occupying a half of each pick, and which weftthreads are transferred after each pick into opposite sides of the bag, thus closing the ends of the bag, the bottom of the same being formed by interlacing all the chain-threads with the two weft-threads.

2. A seamless bag composed of a set of chain-threads and two weft-threads which make continuous passages around the bag in opposite directions, crossing each other first at one end of the bag and then at the other to close said ends, the said weft-threads being interlaced with all the chain-threads to form the bottom of the bag.

In testimony whereof I have hereunto set my hand this 29th day of May, A. D. 1889.
