To all whom it may concern.-

Be it known that I, MARY Anion Evan's, a citizen of the United States, residing at Poplar Plains, in the county of Fleming and State of Kentucky, have invented new and useful improvements in Safetylflnvelops, of which the following is a specification.

This invention relates to safety envelops, the main object of the invention being to provide a simple and inexpensive construction of envelop of this character which when sealed cannot be opened for inspection or abstraction of its contents without giving visual evidence of the fact that it has been tampered with.

A further object of the invention is to provide an envelop which may be used as a letter sheet envelop, or as an envelop having a safety receptacle for a letter or other written message and a space upon which an additional message may be written or matter of any kind printed.

lVith these and other objects in view, the invention consists of the features of construction, combination and arrangement of parts hereinafter fully described and claimed reference being had to the accompanying drawings, in which;

Figure 1 is a plan view of the blank from which the envelop is formed. Fig. 2 is a rear elevation of the envelop as it appears prior to the closure of the top sealing flap. Fig. 3 is a view of the sealed envelop. Fig. 4 is a section thereof, taken on an enlarged scale, on the line 4-4 of Fig. 3.

Referring to the drawings, 1 designates the body or front of the envelop, which is provided with tapering end flaps 2 and 3 a bottom or rear flap 4 and a top sealing flap 5. Each of the flaps 2 and 3 is formed .with gummed edges 6, and the end of the flap 3 has a terminal tongue 7 formed with a gummed inner face 8. The flap is provided with gummed edges 9 and is provided with a central tongue 10 gummed on its inner face, as shown.

The flap 2 is formed with a vertical transverse slit 11 and outwardly beyond the same with ashorter horizontal slit 12, while the flap 3 has a horizontal slit 13, which registers with the slit 12 when the said flaps 2 and 3 are folded upon one another.

The bottom flap 4 is formed with auxiliary end flaps 14 and 15 and with an auxiliary sealing flap 16, the flap 14 having the inner face of its outer end gummed, as at 17 while the edges of the flap 16 are gummed on their inner face, as at 18.

In the use of my improved envelop as a letter sheet envelop, the communication may be written upon the inner faces of the eX- tended flaps 1 and 4, after which the envelop may be folded and sealed by folding the flap 15 over upon the flap 4, folding the flap 14 over upon the outer side of the flap 15 and securing it thereto by its gummed face 17, folding the flap 16 over upon said flaps 14 and 15 and securing it by its gummed faces 18 thereto, and folding the bottom flap with its folded auxiliary flap over upon the rear face of the flap 1. The envelop is then completed and secured by folding the flap 3 over upon the bottom flap and the flap 2 over upon the flap 3, passing the tongue 7 through the slit 11 and gumming it to the outer face of the flap 2, and finally turning down the flap 5 and gumming it to the folded flaps 2 and 3 and passing its tongue 10 through the slits 11 and 13 and gumming it to the outer face of the flap 4. lVhen the envelop is then folded and closed it will be apparent that it cannot be opened for inspection of the matter contained on the flaps 1 and 4 by the process of steaming or in any other way without giving visual evidence of the fact that it has been tampered with.

If desired, a letter or communication written upon a separate sheet of paper may be inclosed within the receptacle formed by the flaps 4, 14, 15 and 16, which are then folded over upon the body 1 and the envelop closed in the manner previously described. This letter or communication will thus be securely contained and protected from abstraction without rendering it apparent that the envelop has been tampered with. In such contingency the inner face of the flap 1 may or may not be employed as a letter sheet upon which auxiliary or additional matter may be written.

From the foregoing description, taken in connection with the drawings, it will be seen that my invention provides a comparatively simple and inexpensive construction of envelop which is admirably adapted for the purposes mentioned and affords increased conveniences in use, as well as protection against surreptitious opening without detection.

I claim An envelop comprising a body having a bottom flap, end flaps and a top sealing flap, the latter being provided with gummed sealing flap upon said bottom liap having 10 edges and a gummed tongue, one of said end gummed edges for attachment to sald end flaps being PIOVldECl with a longltudmal re-v flaps.
