BREGIFICATION forming part of Reissued Letters Patent No. 10,083, dated April 11, 1882. Original No. 227,350, dated Key 11, 1880. Application for reissue filed November 29,1881.

To all whom it may concern.-

Be it known that I, MARK L. DEERING, a citizen of the United States, residing in the city of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful- Improvements in the Manufacture of Paper Bags, of which the following is a description. The nature of this invention relates to forming paper bags with such bottoms that said bags, when distended, shall have fiat bottoms of rectangular form on which to stand erect and unsupported when filled; and said invention consists in the method or process of man ufacture, as well as in the article of manufacture produced.

The outlines of Figure 1 represent a sheet of paper or blank from which to make a bag. The several lines drawn across the blank indicate the first foldings of the paper in the Fig. 2 represents a side view of the blank folded up to form a bottomless cylinder or tube 'with bellows-side folds, shown as compressed together, or nearly *so. Fig. 3 represents an edge view of such a 2 5 cylinder, tube, or body of the bag when distended. Fig. 4' represents a view of the tube orbody of the bag in the second folding of the process of forming the bag. Fig. orepresents the third foldings in the process, the bottom 0 being distended, and, together with the sides of the tube or bag, shown as compressed or laid flat. Fig. Grepresents an edge view of the tube or bag folded as in Fig. 5 as it appears when its bellows-side folds and bottom folds 5 are extended so as to form a rectangular tube with straight walls, and particularly shows the various creases made by the foldings as exposed by one side wall of the tube. Fig. 7 represents a similar edge view of the tube or bag, but with its bellows-side folds partially compressed, the side laps of its bottom folded inward,and the triangular portions of its bottom partially bent inward, the final lapping portions of the bottom remaining extended. Fig. 8 represents an edge View of the tube or bag when its parts, disposed as in Fig. 7, are wholly compressed or flattened down. Fig. 9 illustrates the fourth folding of the tube or bag. Fig. l 0 illustrates the. fifth folding, which 5 completes the bag. Fig. 11 illustrates an inside view of the bag-bottom folded as shown I in Fig. 10 when its forward and rearward and side lappings are opened. Fig. 12 is a perspective view, showing the bagas opened out in use, the upper port-ion beipg, for convenience, shown as removed. I

v In order to make the said bag, a sheet of paper, termed a blank, (represented by the outlinesAof Fig. 1,) is folded by any suitable means in direction of the lines Band C. The

lines 13 form the corners of. the bag when extended as in Fig. 12. This folding is the first in the process of making the bag. The two sides A A are then brought together and lapped one upon the other, as seen in Fig; 2, and secured by pasting or otherwise. The dotted lines C in Fig. 2 correspond with the lines C in Figs. 1 and 3. The body of a bagtube thus formed, by foldings on the lines BC and lapping of the sides A A produces a. rectangular tube when distended, as is shown in Fig. 3, and when the sides are compressed together, as is shown in Fig. 2,1;he lines C of Fig. 1 are indicated by the folds'O in said Fig. 2. This completes the first foldings in the process of making the bag and produces a so-ealled bellows-sided tube.

The bottom of the bag is now 'to be made. To this end acertain portion of one end of the tube, on being compressed together, is creased and doubled back. onto the bag, making a lap, E, Fig. 4, and the crease (1-, (shown in Fig. 6.)

This makes the second foldingin theprocess.

said laps extends forward of said crease, as

shown at c 'c in Fig. 5. This manipulation of the bag not only forins the two side laps, GG, biit also the triangular folds H ll, Figs. 5, o, and 1]. A portion of one lap G isshown as torn. away to expose the triangular fold.

- The fourth fold in the process is made by foldingthe forward portion of thelaps G along the line 0, Fig. 5, and doubling it down upon the bag, forming the lap I, Fig. 9, which is se- The fifth told is made in'like manner by folding over onto the lap I the rearward portion of the laps G G, which is folded along the line m, Fig. 5, forming the lap J ,Fig. 10, which in like manner is secured with past-e applied to the edges of the lap. Itis not essential that the lapIbe first made. 'lhr ap J may be made first and the lap I doubled onto'it This last folding completes the bottom of the bag, an external view of which is shown in Fig. 10.

In making 'bags it is not necessary that a single sheet or blank shall be, used for each bag. Along strip of paper may be treated with the first foldings and pasted, as-herein described of the blank Fig. 1, thereby fennin g a long tube, which may be cut into lengths for bags.

The bag, herein deseribed is represented as an oblong square; Bags, however, of other rectangular forms ean be made by the same or similar folding-s and laps without changing the nature of the invention. 7 a What I claim isv 1. The herein-described process or method .of forming paper bags by making in a sheet of paper or blank the folds B and C, then pastine together the two sides A A forming a bellows-sided body or tube of the bag, then spreading open one end of said body or tube, then fo'rining the inwardly-pro eeting triangular folds II II, side laps,.G G, andlaps I .l, which latter are seeuredin place by pasting or otherwise, substantially as described.

2. A- bag consisting of abellows-sided tube having a satehel-botton1 and inward triangular folds, which form pa rt of its tu'osides when distended.

In testimony whereof I have hereunto signed my name this 14th day of November, 1881.
