FABRIC BAG.

y Application filed Januaiylefll. Serial No. 439,744. h

To all 'whom t may concern: p

Be it `known that I, JAMns P. Hoeren, a citizen of th'e United States of America, residing in Buxton, Baltimore County, State of hi/laryland,` have invented certain new and `useful improvements in Fabric `Bags7 of which. the following is: a specificar tion.

The invention relates to a bag of textile `or `woven fabric particularly adapted for use as a mail bag, coal bag or the like. The manufacture of bags for such purposes of "textile `fabric is understood to have been practiced for many years but such bags have been subject to failure by ripping of the seams and wear, particularly at the bottom.

'lhe object of the present linvention is to `overcome these defects and produce a bag which can be manufactured at -a minimum y cost as to time and labor.

In the manufacture of the bag which is the subject of the invention in the preferred Vform the first step is the production of a tube of woven fabric, the sides of which are transversely interwo-ven at intervals so that the tubular fabric may be cut into bags by severing between the transverse interwoven portions. The present invention further includes so cutting thebag as to provide as a partof each severed section a portion of the tube extending considerably beyond the transverse interwoven portion which part `may be turnedup against the sides ofthe bag forming an external Nreinforce which protects the bottoni vof the bag from wear` secured, each warp in fact forms a contin- `uous loop extending from the top of the y reinforce downward, aroundthe bottom of the bag and up on the opposite side to the top edge of the bag.

`lin the accompanying drawing I have illustrated a bag constructed in yaccordance with my invention and also a length of tubular fabric with the warp crossed at intervals ready to be cut into lengths from which ybags may be constructed in accordance with my invention.

smaller scale.

In the drawing Fig. 1 is a central longitudinal section through a finished bag.

F ig. 2 is an elevationof the bag on a Fig; 3: is an enlarged diagrammatic section show-ing the arrangement of the threads in the fabric before folding to forni the reinforce, the plane of the section being parallel to the plane of the section of l.,

Fig. flis a view of a portion of the tube in a fabric ready to be cut into bags, the same being on a reduced scale.

Referring` to the drawings by numerals the construction illustrated consists of a bag l. composed of a section of tubular woven fabric 2, the bottoni of the bag being formed by interweaving the opposite sides of the tube producing a transverse interwoven portion 3 extending from side to side of the bag and tube. As cut the tubular fabric extends beyond the interwoven` portion 3` and is turned upward preferably on the outside of the bag forming a reinforce 4- which niay be hemmed at the edges at 5 and seamed to the sides of the bag at 6.

ln the form of the invention shown and preferably the warp threads 7 of the fabric forming the tube are crossed at 3 to produce the transversely extending interwoven portionso that each warp thread in the iinished bag having the end of the tube turned up to form the reinforce 4, extends down one side of the bag from the mouth or top 8 to the interwoven portion 3 and up the other side of the bag where it is woven into and forms part of the reinforce 4l. This produces a bottom structure which is incapable of ripping and is without any weakened portions at all. In fact it is a bag with a double bottom having all the other advantages of a double weight continuous warp fabric, throughout the bottom portion. At the saine time it is as easy and cheap to produce as the ordinary bag formed of tubular fabric which canbe no stronger than its weakest point, i. e., the bottom seam. The process of weaving the transverse interwoven portion is quicker and easier to produce as well Ias stronger than ordinary sew-` ing. Practically the only additional expense of construction being that incident to the actual cost of the extra length of fabric forming the reinforce 4. The inanner of applying this reinforce to the structure as hereinbefore described is cheaper than any other known method of reinforcing including the obvious method of sewing lan ext-ral thickness of fabric to the inside or ontside of the bag.

Havingl reference to Fig. .4l of the drawing l have illust-rated a tubular fabric 9 interwoven at intervals at 3 adapted to be cnt transversely at convenient points las indicated by reference character ll to produce tubular sections troni which the bags may be conveniently constructed in accordance with any invention. Each sect-ion as shown includes a reinforcing portion t.

have thus described speciically and in detail a. bag; embodying niy invention in the preferred forni, however, the specific terms herein are used descriptively rather than in a limiting sense, the scope ot the invention being defined in the claim.

lha-t I desire to secure by Letters Pnl'- ent is A bag composed oi' tubular textile fabric having the opposite sides interwoven by crossingy 'the warp, the tubular fabric beyond the internf'oven portion being,` turned np against the sides ot' the bi1-g and secured at the edges whereby the respective warn threads are caused to extend down one side ot the bag, around the bottoni and up on the opposite side.
