UNITED STATES PATENT OFFICE.

E. L. BARRETT, or SPRINGFIELD, 01110,

ENVELOPE.

Specification forming part of Letters Patent No. 50,549, dated October 24, 1865.

To all whom it may concern:

Be'itknown that I, E. L. BARRETT, ofSpring- .field, in the county of Clarke and State of Ohio, have invented certain new and useful Improvements in Envelopes for Filing and Transmitting Papers, being a new article of manufacture; and I do hereby declare that the following is a full and complete description-of the same, reference being bad to the accompanying drawings, making a part of this specification, in which .Figures 1, 2,3, 4, 5, and 7 represent the differentforms required in the process of manu-- leather, or other suitable material, and is of the form or shape shown in Fig. l. The middle part, B, extends up and is curved round into a lapel, as seen at B, and the other end, a, extends below the sides AA. The side parts, A A, are folded over onto the center part, at the lines I) b by first laying down the side Aand then the side A(, which is wider than the other side, and laps over onto it, as indicated by the dotted line b in Fig. 2, where they are pasted together, or the wide side can be put under the narrow side, as indicated at f in Figs. 3 and 4. The sides A A form the part opposite the middle or back B of the envelope. The end piece, a, is then turned up and pasted down on the lower end of the side A A, and the lapel B can be turned down from the top. The dotted line a indicates the lower end of the side AA. A square is now out 0d the lower corners, c, Fig. 1, as shown end, but only over the open corners.

at c in Fig. 2, to allow the expansion of the envelope before attaching the gussets. The sides from e to 6 across and from c. to c lengthwiseyas notedby the red lines in Fig. 3, are doubled inwarrhand likewise the lower end, a, as represented in Figs. 4 and 5. The envelope is thenplaced on a stuffer or block, of a suitable shape and size, being of a thickness equal to the sides and end that are folded inward. When the envelope is thus adjusted on the block a gusset, O, of cloth, leather, or other material, (represented in Fig. 7,) is then pasted down on the end a, over the corners'c, and up on the sides, as shown in Fig.

The gusset 0 need not extend all along the The end of the envelope is rendered stronger by the gusset covering the end.

The envelope is now completed, as in Fig. 5,

forming a case or receptacle to contain papers or documents of any kind without cramping or injuring the edges.

Fig. 6 represents an envelope of the ordinary form, out out a different shape, but made in the same manner, with gussetsd over the open corners. This envelope can be made of any form or size; and as the sides and ends or g'ussets are folded inward bellows -shaped it will expand more or less,'according to the thickness of the package inserted.

These envelopes are very convenient for mail and express packages, and for all kinds of otfice use. They are packed and sent in pack-- ages like ordinary envelopes. What I claim as my improvement, and dcsire to secure by Letters Patent, is-

The herein described expansion envelope,v when constructed as specified, for the purpose set forth, being a new article of manufacture.
