SAFETY-ENVELOP.

Specification of Letters Patent. Patented Aug. 10, 1920.

7 Application filed September 6, 1919. Serial No. 322,057.

To all whom it may concern:

Be it known that I, MARY R. GEYER, a

citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Envelops, of which the following is a specification.

. This invention relates to an improved type of envelop and it has for its principal object to provide a container which maybe used to transmit money and the like through the mails without danger of having the envelop steamed open and the valuables extracted therefrom by unauthorized persons. Also the provision of an envelop which may be constructed in accordance with the above and from a single sheet of material, there being but a minimum of waste in the manufacture thereof.

In the accompanying drawings, Figure 1 is a plan of the blank of which the envelop is made; Fig. 2 is a perspective detail showing the first forming; Figs. 3, 4, 5 and 6 show the succeeding-steps in the forming of the completed envelop.

The envelop comprises three rectangular portions 1 2, and 3, and the portion 1. has formed on one of its longer edges a triangular flap 4 and at one of its shorter edges a similar shaped flap 5, said flap extending" across the shorter edge of the portion 2 and freed therefrom, the portion 2 has secured to its side a triangular flap 6 which is identical with the flap 5 and extends across the end of the flap 1. The portion 3 has secured to one of its shorter edges a short rectangular flap 7 and to its other edge a second flap 8.

The parts 1, 4, 5 and 6 are gummed over their entire areas upon one side only and the parts 7 and 8 are likewisegummed upon their opposite faces for a purpose to be described.

WVhen forming the envelop the flap 8 is first folded on the line 11, in upon the porcovered tion 3 which is then folded upon the dotted line 9 over upon the portion 2 and these two portions are then folded on the dotted line 10 upon the portion 1, the face of the portion 1 being gummed, the portion 3 adhering thereto and a pocket being formed between the portions 2 and 3. The flap 8 having as stated been folded on the dotted line 11, and being gummed on the proper side is secured to the inside of the portion 2, closing the pocket formed by the portions 2 and 3 at one end thereof. To reinforce this end the flap 6 is then folded upon the dotted lines 12 and 13 and secured to the outside of the portions 1 and 2.

This condition puts the envelop in the form shown in Fig. 4 which is the correct condition for receiving the mail matter, which after insertion into the aforesaid pocket is confined therein by folding the flap 7 inside of the pocket and sealing, said flap being reinforced by the flap 5 being folded and sealed into place as shown in Fig. 5. All seams and joints are then closed by the flap 4: being brought over and sealed upon the edges of the flaps 5 and 6 and the unpart of the portion 2, this puts the envelop in the condition show in Fig. 6, ready to receive the proper address upon its face and for mailing.

I claim:

An envelop comprising two body portions folded upon each other, having a fiap folded against the other, and each of said body portions having a triangular flap at one end thereof, said flap being folded to close the end of the envelop and against the outer surfaces of both of the body portions.

In testimony whereof, I do afiix my signature in presence of two witnesses:

MARY R. GEYER.
