ENVELOPE.

SPECIFICATION forming part of Letters Patent No. 491,928, dated February 14, 1893.

Application filed December 11, 1891. Renewed November 2, 1892. Serial 110,450,780. (No model.)

To @ZZ whom it may concern,.-

Be it known that I, ANsoN R. SPEAE, of Devils Lake, in the county of Ramsey and State of North Dakota, have invented certain new and useful Improvements in Envelopes; and I do hereby declare the following to be a full, clear, and lexact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and improved envelope designed for the safe and convenient transportation of samples of Inerchandise, cards, photographs, and the like, and grain or flour, and it is especially designed as an improvement over the envelope shown and described in Letters Patent No. 433,052, granted to me July 29, 1890.

The object of my invention is to provide an improved envelope in which such articles can be safely transported, and which can be securely closed by folding the parts together, all danger of such parts pulling out or sepa rating being avoided.

The invention consists in providing an envelepe composed of two parts, one of which parts is bent or folded to form a pocket which is held by the overlapping longitudinal edges of the other part., the extended ends or flaps of said parts being bent or folded together diagonally, and then bent down into said pocket, substantially as hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying dravvingsz-Figure 1 is a view in perspective of my improved envelope. Fig. 2 is a longitudinal sectional view thereof. Fig.,3 is a plan view showing the first fold given the flaps. Figl isatransverse sectional view on the line ac w, Fig. 3, showing the pocket secured bythe overlapping longitudinal edges. Fig. 5 is a longitudinal sectional view showing the envelope closed.

Referring to the drawings, A designates the body of the envelope which is composed of two parts or sections a, a, the longitudinal edges a2 of the latter being bent down over and secured to the corresponding edges of the former. This envelope may be of any preferred size or shape and of any suitable material. The part a of the envelopeis bent back upon itself to forin a pocket b. This pocket is held rmly in place by the overlapping edges a2 of the part a. At the open end of the envelope are the flaps B, C, which are elongations of the part a, a', respectively. These flaps are provided with transverse scores or creases b', which extend parallel with the pocket and the ends of the flaps, and also with two diagonal scores or creases b2, which extend from the outer ends of the scores or creases b convergently to near a meeting point at the center of the outer edges of said flaps.

When it is designed to close the envelope, the ends or corners of the flaps are folded 'inwardly on the scores or creases b2, and then tally open no matter how bulky its contents.

By forming the pocket in the manner stated and securely fastening the same by the overlapping edges of one of the two parts composing the envelope there is a great saving in labor and a stronger and better fastening is secured.

I claim as my invention- 1. An envelope composed or two parts, one of which has its longitudinal vedges overlapping those of the other, said latter part being bent to form a pocket which is fastened by said overlapping edges, both of said parts be'- ing provided with flaps which are designed to be folded down into said pocket, substantially as set forth. v

2. Theherein-describedimprovedenvelope, comprising the body composed of two-parts a, a', the longitudinal edges of the latter overlapping those of the former, said part 'a being bent to form apocket which is secured by said overlapping edges, and the corresponding flaps which are provided with a longitudinal score or crease parallel with the edge of said pocket, and with two diagonal scores or creases, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
