G. l. GOLDWYN BAG Filed March 3l, 1930 Patented Jan. 10, 1933 PATENT OFFICE GEORGE I. GOLDWYN, F CHICAGO, ILLINOIS :BAG

Application led March 31, 1930. Serial No. 440,200.

which are then stitched together, thus leaving the bag open at one end.

The primary object of the invention is to provide an improved manner of securing marginal parts of associated bag Walls together as a seam, which seam is strong and durable in service and is neat in appearance.

A further object of the invention is to provide an improved seam for the bag which is practical to make and which eliminates 0 the necessity of turning the bag inside out during the making thereof.

Still another object of the invention is to provide a bag seam wherein marginal parts of the bag walls are each folded to provide .25 a plurality of thicknesses that are turned back upon the bag walls and are secured to said Walls in a manner eliminating any frayed or raveled edges.

These objects of the invention as Well as others together with the many advantages thereof will more fully appear as I proceed with my specification.

In the drawing Fig. l is a perspective view of a bag embodying my invention.

Fig. 2 is a sectional view on an enlarged scale through a partially completed bag seam embodying one form of my invention.

Fig. 3 is a sectional perspective view showing the finished seam after certain further operations have been carried out on the partially finished seam of Fig. 2.

Fig. 4 is a view similar to Fig. 3 showmg another seam structure embodying my in- -vention.

Fig. 5 is a detail sectional view through a seam embodying a further modified form of the invention. i

Referring now in detail to that embodiment of the invention illustrated in Figs. 1

to 3 inclusive, l indicates as a Whole a textile bag such as burlap having side walls 2 and 3 respectively which are secured together along the bottom end and along one side thereof to leave an open mouth at the 5 other end thereof. In accordance with one embodiment of the invention, the lateral margin 2a and 3El respectively of each bag Wallis turned over upon the outer surface of the associated wall and a line of stitching 4 is then run along said margins to secure the bag walls and turned over margins 2a and 3a respectively together. Thereafter the free edge portion 2b and 3b respectively of each marginal part which is usually more or less frayed or raveled isturned over in a reverse direction upon the other portion of said part so as to enclose or cover the line' of stitching 4. Thereafter a line of overcast stitching 5 is run in just within the folded over portions of the bag walls with the transverse loops 6 of the same passing about s aid folded over margins to bind in place all ravellings at the edges of both portions 2b and 3" respectively of said marginal parts.

In burlap bags which are always more or less loosely Woven, the edges of said marginal portions are generally frayed or raveled and said edges tend to Slough off as lint in the use of the bag, when such edges are exposed and this is not only objectionable as a matter of untidy appearance but is also objectionable because there the bag quickly Wears away. However, in my improved bag the edges of said portions of said marginal parts are bound in place so that they cannot Slough off as lint and a much neater appearance is given to the bag as a Whole.

In this respect it is pointed out that the invention may be used in the remade bag industry because when a burlap bagsuch as is now used is turned inside out it resents a seam such as is shown in Fig. 2. take such a bag and turn over the free edgey portions 2b and 3b respectively of the marginal parts 2a and 3a and then run the stitching as before mentioned and the remade bag is thus provided with a much stronger and neater seam than it had before.

In making new bags, I may if desired eliminate the stitchin 4 before mentioned and so locate the line o stitching 5'L that it passes through not only both bag Walls 2 and 3 but 5 also through both the edge portions 2b and 3b adjacent the line of fold with the margins a, the loops 6 passing about the outer edge portions of the seam as before so as to bind the frayed or raveled edges of the por- 10 tions 2b and 3b in place as before. Such an arrangement is best shown in Fi 4:.

In Fig. 5 I have shown a modi ed form of construction somewhat similar to that shown in Fig. 3 the only difference being that i11- stead of turning the portions 2b and 3b back over upon the portions 2a and 3a I turn said portions 2b and 3b back under said portions 2 and 3a respectively. Thus when a line of stitching 5b is run in, the loops 6b enclose the edges as before and the frayed or raveled edges of the portions 2b and 3b are more effectively protected and concealed.

It is apparent that a bag embodying my invention is provided with a good strong and neat appearing seam which can be readily produced at a low labor and material cost.

While in describing my" invention, I have referred in detail to the' form and arrangement of the parts thereof, the same is to be considered merely as illustrative so that I do not Wish to be limited thereto except as may be specifically set forth in the appended claims.

I claim as my invention 1. A bag having side walls, a marginal part of each of which is folded to rovide a plurality of thicknesses turned bac upon the outside of associated side walls, and means securing said side walls together as Well as V securing said marginal parts thereto and to each other, said means including parts that pass about the folds of said margins and provide a bound edge for the bag. v

2. A bag Ahaving side walls', a marginal part of each of which is folded to provide a plurality of zigzag thicknesses turned back upon the outside of associated side walls, and stitching passing through said side walls as Well as binding said thicknesses in place and to said side walls of the bag.

3. A bag having side Walls, aprnarginal part of each of which is folded over in one direction upon the outside of an associated side Wall, a portion of said marginal part being refolded in the other direction and engaged under the first mentioned portion of said marginal parts and stitching securing said side walls together as Well as securing said marginal parts together and to said side walls, a portion of said stitching passing about the folds of said margins and providing a bound edge for the bag.

In testimony whereof, I have hereunto set my hand, this 28th day of March, 1930. l GEORGE I. GOLDWYN.
