PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 363,596, dyed May 24, 1887.

Application liled July 30, 1886. Serial No. 209,591. (Melel) To @ZZ whom it may concern.-

Be it known that I, EDWARD E. OLAUssEN, of Hartford, Connecticut, h ave invented anew and useful Improvement in Paper Bags, of

which the following description and claim constitute the specification, and which is illustrated by the accompanying two sheets of drawings.

This invention is a new and useful squarero bottom paper bag.

Figures l, 2, and 3 of the drawings are a side view, an edge View, and an end view, respectively, of a length of tucked paper tube suitable to be manufactured into my new bag.

1 5 Figs. 4 and 5 are an edge view and aside view, respectively, of the blank of Fig. 1, after its lower end has been opened up by means of a truncated triangular -implement like that a plan View of the flat working end of which is shown in Fig. 6. Figs. 7 and 8 are a side-view and an edge view, respectively, of the blank f Figs. 4 and 5, after its lower end has been still farther opened out. Figs. 9 and 10 are a side and an edge view, respectively, of the blank of Figs. 7 and 8, after its lower end has been opened out to its fullest extent and the pouch E has been made and flattened down and the implement of Fig. G has been withdrawn from the pouch and from the blank. Figs. 11 and 12 are a side and an edge view, respectively, of the blank of Figs. 9 and 10, after the side walls of its open end have been folded down upon thesurfaces beneath. Figs.

13 and 14 are a side and an edge view, respect- 3 5 ively, of the blank of Figs. 11 and l2, after the upper wall of its opened-out and foldeddown end has been turned and folded back toward the body of the blank and the diamond77 form shown in Fig. 13 has been thus 4o produced. Fig. 15 is a view of the blank of Figs. 13 and 14, after the upper end of the diamond has been folded forward upon the adhesive surface of the middle portion thereof, while Fig. 16 is aview of the blank of Fig. 15,

after the lower end of the diamond has been folded back partly upon said adhesive surface and partly upon the extremity of the foldeddown upper end of the diamond, and the bag has been thus completed. Fig. 17 is an isometric view of the bag of Fig. 1G, opened out 50 to be used, and showing its bottom upward.

A'is the upper wall, and B and C are the side walls, of the opened-out end of the blank in its various stages of transformation, and D is that part thereof which is madeto form the lower end of the diamond.A

E is the pouch which gives this bag its novelty and its peculiar utility. It forms the lower portion of one side of the bag when the bag is opened out, as in Fig. 17; and its form 6o and construction will be understood from the following description of the process of making the bag:

The tube of Fig. lis pressed down upon any fiat surface by any straight-edged implement along and above the dotted line a; a: in that iigure, while the lower plies of the tucked in edges of the blank are held down upon the same surface by two straight-edged imple ments along and above the dotted lines y y, 7o respectively; and the lower wall of the tube is preferably held down upon the same surface by any suitable implement pressing upon the point D. Then the implement F is inserted in the lower end of the blank, above its inwardly-projecting tucks, far enough to carry its forward lateral edge to a line between the most advanced points of the dotted diagonal lines g/ y. Then that implement is elevated and advanced in such a way as to carry its 8o forward edge in a semicircle, of which the dotted linex m is the center, to the position indicated at E in Fig. 10. Vhile that movement of the limplement F is occurring, any straight-edged implement may be pressed down above it on the outside of the blank. along the line z z of Fig. 9, so as to assist the implement F in its work; and that wo rk may still further be assisted by means of any thin straight-edged implement pressed laterally into that fold the inner crease of which is represented by the line v in Figs. 8 and 10, and by another' similar implement pressed into the si milar fold in the other edge ofthe blank of that figure. f Thus the lower end of the blank of Fig. 1 is opened out into the forni of that of Figs. 9 and 10, through the intermediate transformations shown in Figs. 4 and 5, 7 and 8,

respectively. Then the implement F and its assisting implements are withdrawn, and the side walls, B and C, are folded down upon the surfaces beneath by means of a tlat implement pressing upon them from their lower ends upward as far as the base of the upper wall, A. That pressing operates to fold the ripper wall into the form of a truncated right-angled triangle, as indicated in Fig. 13, where that wall is shown as turned backward to a horizontal position upon the body of the blank. But that wall needs not to be thus turned, for it may be left in the position shown in Figs. 11 and l 12, while paste is applied to the residue ofthe diamond in the double line indicated by the lettcrG. Vhether or not thewall Ais turned backward to a horizontal position before the paste is applied to the blank, after that event, that wall, which has now become the upper ap ofthe diamond, is folded forward and pressed down upon the pasted su rface, as shown in Fig. 15. Then the lower flap, D, is folded back upon the middle of the diamond and upon the flap A, as shown in Fig. 16, and the bag is thus completed.

Among all the prior paper bags known to ine the nearest approach to this of mine is that indicated in the drawings of Reissued Letters Patent of the'United States, No. 10,083, dated April 11, 1882, and granted on the alleged invention of Mark L. Deering. My bag differs from that one in respect of having the pouchA E. In the Deering bag the paper whichforni into thatpouch is folded'forward under the square bottom of his bag, where lts presence is objectionable, because it makes the flattened bag shown in Fig. 10 of Deerings drawings thick and comparatively clumsy at that place; but. the makingY of the pouch E enables nie to render more nearly uniform the number of thicknesses of paper under the various portions of the presented surfaces of my bag, as shown in Fig. 16. Therefore,'when my bags are alternately reversed upon each other and are packed into bunches for sale or for shipment those bunches are nearly uniform 1n thickness between all portions of their horizontal surfaces, and. are nearly uniform in compactness throughout their interiors,whereas bunches of Deering bags are much inferior to mine in both these desirable respects. Moreover,the pouch E is particularly useful, in that the elasticity of its folds aids the side folds or tucks ofthe bag in causing the bag to spontaneously open when the two flat thicknesses of paper at its mouth are separated by a person whois about to fill the bag with merchandise.

A square-bottom paper bag having the pouch E, substantially as described.
