FLEXIBLEBAG.

SPECIFICATION forming part of Letters Patent N 0. 735,560, dated August 4, 1903.

Application filed December 5, 1902 Serial No. 134,004. (No model.)

To all whom it may concern:

Be it known that I, JOSEPHINE MI L TLLER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and useful Improvement in Flexible Bags, of which the following is a full, clear, and exact description.

My invention relates to improvements in the construction of flexible bags.

The purpose of the invention is to provide a construction of flexible bag wherein a fabric is employed woven in a tubular shape and closed in weaving at one end, which tubular fabric is folded upon itself in such manner that the open end of the tubular fabric is carried inward in direction of the closed end and its open end is concealed, thus producing a bag made in one continuous tubular length, which comprises an outer wall or member and an inner wall or member independent of the outer one, the two walls being without a seam at the mouth and sides of the bag and the outer wall being without a seam at its bottom.

Another purpose of the invention is to provide draw-strings which extend through loops woven in the outer side faces of the bag,which draw-strings are interwoven or caged in said.

terminal above the free end of the adjoining draw-string.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective sectional view of the improved bag. Fig. 2 is a vertical sec-' tion through the bag, and Fig. 3 is atransverse section taken practically on the line 8 3 of Fig. '1.

The bag is constructed of a flexible material, a woven fabric being preferably used, and this fabric is produced in tubular form with one end 10 closed in the process of formation, while the opposite end 11 is open.

In the formation of the tubular woven fabric composing the body of the bag, at a predetermined distance from its closed end 10 at each 'side of said tubular body, a transverse series of longitudinal loops 12 is formed, as is shown best in Fig. 2, and, further, in the production of the tubular body fabric the aforesaid loops 12 are made to cross and form guide-inclosures for two draw-strings A and B. Each draw-string is doubled upon itself to form two members, which members enter the guide-loops from opposite edges of the tubular body fabric of the bag, and the two draw-strings are preferably placed one above the other, so that in action one will not interfere with the other. I

A member of each draw-string A and B passes through the guide-loops 12 at each side of the tubular body fabric, and the free ends 13 of one draw-string are below or are associated with the loop 14 of the opposing draw-string.

In the formation of the bag the tubular fabric body is folded, as shown in Figs. 1 and 2, so as to carry the open portion 11 of the body within the closed-end portion 10, the fold being made at a point above the guide-loops 12 of the body and the draw-strings A and B, thus producing outer walls 0 and inner walls D,- one independent of the other, from top to bottom of the bag. The open lower end of the inner member or wallD of the bag is closed by stitching or in any other approved manner, as isindicated in Figs. 1 and 2. Under this construction a flexible bag is formed of a continuous tubular body having independent inner and outer walls, seamless edges 15 at the mouth, seamless side edges l6,and a seamless bottom edge for the outer wall; but the corresponding edge of the inner wall is closed, as'stated, in the completion of the bag, and, furthermore, the draw-strings are placed in position during the formation of the tubular body and are thus seated most economically and to the best advantage, being interwoven 0r caged, thereby adding materially to the strength of the article.

I desire it to be understood that while I prefer a woven fabric as the material from which to make the bag any flexible material in tubular form and corresponding seamless condition is included within the scope of the invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A flexible bag consisting of a continuous tubular flexible material folded upon itself to form two walls, an inner and an outer wall independent one of the other, the said bag being seamless at its mouth edge and at the bottom edge of its outer wall, as set forth.

2. As an improved article of manufacture, a flexible bag consisting of a continuous tubular fabric having a continuous closure at one end and open at the other, which fabric is folded upon itself to form outer and inner independent walls, the mouth-section and outer bottom section of the bag, together with the side edges of bothwalls, being withouta seam,

, as specified.

3. Asa new article of manufacture, a flexible bag consisting of a continuous tubular fabric having a continuous closure at one end and open at the other, which fabric is folded upon itself to form outer and inner in dependent walls, the mouth-section and outer bottom section of the bag, together-with the side edges of both walls being without seams, and the bottom section of the lining or inner wall of the bag being connected by a closing medium, as specified.

f. A flexible bag consisting of a continuous tubular fabric having a continuous closure at one end, which fabric is folded upon itself to form outer and inner independent walls, the mouth-section and outer bottom section of the bag being without a seam, likewise the side edges of both walls, means for closing the bottom portion of the inner wall, a transverse series of loops formed at the outer face of the outer wall, and draw-strings passed through said loops, as set forth.

5. A flexible bag consisting of a continuous tubular fabric having a continuous closure at one end, which fabric is folded upon itself to form outer and inner independent walls, the mouth-section and outer bottom section of the bag being without a seam, likewise the side edges of both walls, means for closing the bottom portion of the inner wall, a transverse series of loops formed at the outer face of the outer wall, and draw-strings passed through the said loops from opposite edges of the bag, a memberof each draw-string extending out at each side of the bag and the loop of one draw-string being adjacent to the free ends of the adjoining draw-string, substantially as described.

(3. A flexible bag consisting of a continuous tubular fabric woven in one continuous length and closed at one end in weaving, the open end of which fabric is carried inward in direction of the closed end, forming inner and outer independent walls, and means for closing the inner open end of the inner wall, whereby initially the bag is formed seamless at the mouth, its sides and the bottom of its outer wall, substantially as described.

'7. A flexible bag consisting of a continuous tubular fabric woven in one continuous length and closed at one end in weaving, the open end of which fabric is carried inward in directionv of the closed end, forming inner and outer independent walls, means for closing the inner open end of the inner wall, whereby initially the bag is formed seamless at the mouth, its sides and the bottom of its outer wall,draw-strings bent upon themselves and carried in opposite directions at opposite sides of the bag, the loop of one draw-string being over the free ends of the opposing drawstring, and transverse series of guide-loops at the outer faces of the outer side walls of the said bag,which guide-loops cross the drawstrings where they engage with the bag, the said loops being passed over the said drawstrings during the formation of the tubular body of the bag, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 4
