` To all whom it 'may concern:

of `Suffolk and State of Massachusetts, have invented a new and useful Improvement in Paper Bags; and we do hereby declare that i `the following is a full, clear, and exact dei nscription thereof, which will enable others 1" skilled in the art to make. and usethe same, reference being had to the accompanying drawi ings, forming part of this specification, in

il which- `Figure l is a plan of the cut or pattern of 'thebag before folding and pasting. Fig.`2 is a plan of the bag half-folded for receiving the paste. Fig. 3 is a plan of the bag when pasted. Similar letters of` reference indicate like i parts.

y This invention relates to an improved mode of making paper bags; and consists in cutting 1the material ont and folding the edges tof gether in' such a manner as to make a conical bagwith a flap cap or cover for securing i i whatever the bag may contain. l Theadvantage of this bag is found in its extreme simplicity and great economy in the use of material, the application of the material being such that the whole .supercies of i `l. the paper is utilized in forming a bag ofthe i y largest possible dimensions, while the narrow "laps employed for folding and pasting the edges together are strong, and `the shape of H the bag `is very convenient for putting things `j into it andsecuring them ina neat package or parcel.

The paper is cut into parallelograms, or equilaterally, as shown in Fig. 1, except at `l `one corner, Where a point is formed by the apex a of a central triangle, a b c,by`cutting smalltriangular piece, a. i 0, 0n each side 'ofthe/apex from the {lap-pieces b e wand c d thus cut inthe pattern of the bag have their UNITED STATES PATENT OFFICE.
