Description
June 9, 1936- o. sPRosTY METHOD OF MAKING DOUBLE BAGS Filed June 8, 1935 m we m ATTORNEY Patented June 9, 1936 um'rso STATES PATENT OFFICE 3 Claims.
This invention relates to a double bag, and method of making the same.
It is the principal object of my invention to provide a double bag that may be made from a single piece of burlap, cotton, paper or other fibrous material by folding a rectangular piece of such material upon itself, then closing its three open sides and folding or telescoping one half of the closed piece into the other half. The double bag which results is highly adapted to receive heavy and fine articles, and more particularly abrasives such as shot. Such a bag is easier to fill than the present double bag, in which it is difficult to keep the articles from getting betweenthe inner and outer bags. However, in my double bag one cannot help but get all the articlesinto the bag, since its dual sides are closed. a
My double bag may be more economically produced than the present type of double bag, and with its double seamed bottom, gives extra strength.
Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.
In the accompanying drawing illustrating my invention, Figure 1 is a plan view of a rectangular piece of burlap before it is folded upon itself as the first step in making my double bag. Figure 2 is a plan View of the burlap piece shown in Figure 1, after it has been folded upon itself and closed at its three opensides by a folded fiat seam. Figure 3 is a side view of the bag after one-half of the closed burlap piece has been telescoped into the other half.
Figure 4 is a longitudinal, sectional view taken through the completed bag on the line 4-4 of Figure 3. Figure 5 is a cross-sectional view taken through said bag on the lines 5--5 of Figure 3. And Figure 6 is a cross sectional view taken through the folded burlap piece, on the lines 6-6 of Figure 2, showing how the three open sides of it are closed by the folded flat seam.
Referring to the accompanying drawing for a detailed description of the double bag which may be made under my method, the numeral designates a rectangular piece of fibrous material such as burlap. It could just as well be cotton, paper or other fibrous material.
The rectangular piece of fibrous material I is longitudinally folded upon itself along the medial dotted line 2 in Figure 1, to form the folded article illustrated in Figure 2. This article, when first folded, is open on three sides and closed on one side. Under my method the open sides are then closed, in this instance by folded flat seams 3, although any other type of scam oruniting means may be employed if desired.
The closed longitudinal piece illustrated in Fig- 10 ure 2 is now ready to be converted into the double bag iillustrated in Figures 3 and 4. This is accemplished by folding or telescoping one-half of the folded, end-closed piece into the other half.
My double bag is easy to fill, because there is no opening between its inner and outer parts at its filling end, as is the case with the present type of double bag.
It is also economically produced, because the folding and seaming operations are few, and can be easily and quickly performed. The bag also has the extra strength which its double, seamed bottom and other reinforced parts give.
I do not wish to be limited to the details of structure of the double bag illustrated in the drawing since any changes or modifications may be made therein within the scope of the subjoined claims.
Having described my invention, I claim:
1. A method of making a double bag of fibrous material, which consists in folding a rectangular piece of fibrous material upon itself, then closing the three open sides thereof, and then folding one-half of the closed piece into the other half.
2. A method of making a double bag of fibrous material, which consists in folding a rectangular piece of fibrous material upon itself, then closing the three open sides thereof by seaming them, and then folding one-half of the closed piece into 40 the other half.
3. A method of making a double bag of burlap, which consists in folding a rectangular piece of burlap upon itself, then closing the three open sides thereof by stitching, and then telescoping one-half of the closed piece into the other half.
