Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed September 10, 1917. Serial No. 190,623.

To all whom it may concern Be it known that I, T-TARRY B. MAxwnnL, a citizen of the United States, residing in the city of Omaha, county of Douglas, and State of Nebraska, have invented certain new and useful. Improvements in Envelope, and have described the same in the following specification, illustrated by the accompanying drawings.

My invention relates to that class of envelops which are commonly made individually of a piece of paper folded flat upon itself and gummed, and are used as coverings for contained letters during transmission by mail. It is the main object of the invention to adapt, in a superior and convenient manner, an envelop of this class to be first sealed by the sender, then opened by a censor for examination 0r treatment of its contents, and afterward rescaled in condition to be forwarded with its contents to its destination. To accomplish this object I incorporate in my improved envelop, as parts thereof, a removable flange which has adhesive matter on one side for the initial sealing of the envelop by the sender, a closing flap, adhesive on the other side, for the rescaling of the envelop by the censor, and an intermediate removable nonadhesive border strip temporarily uniting the flange with the flap.

In said drawings, illustrating the best manner in which I have contemplated applying the principles of the invention, the several figures, numbered from 1 to 6 inclusive, are rear plan views of an envelop which is constructed in accordance with these principles, and is shown at different stages of its use and construction.

In this illustrated and illustrative specimen of my invention, the body of the en velop is a flat rectangular pocket formed in the usual manner between the front wall 7 and its rearwardly folded and stuck-together wings 8 and 9. The removable flange, above mentioned as part of the envelop, is denoted by the numeral 10. To prevent buckling, it is made partly or wholly discontinuous midway of its length, as at 16 in Fig. 1. On one side, corresponding to the face of the envelop, this member is covered with gum arabic, or other adhesive preparation, denoted by shading in Fig. 2. On the other side, it carries the word Censored, or some other legend or distinctive marking of similar significance, as shown in Figs. 1, 4, 5 and 6. The sealing flap, above mentioned as part of my improved envelop, is denoted by the numeral 11. This member is a flat extension from the front wall 7 of the envelop, and is of general triangular form. It is flexibly continuous with the front of the envelop and demarked therefrom by folding backward in the usual manner on the line 12. Along its free edge it is gummed on one side, in the usual manner, as shown by shading thereon in Figs. 1, 2, 4 and 5. These members, the described flap and flange, are symmetrically and integrally united by the intermediate flat strip 13, which is demarked therefrom by the parallel lines of perforations 14 and 15 respectively.

Operatively the letter which is to be in closed is inserted in the face-addressed envelop in the usual manner, while the latter is wide open as in Fig. 1. Then the flange 10 is folded down flat on the strip 13, as in Fig. 2, and duly moistened for sticking. Then the flap 11, carrying the flange and sticky strip in that position, is folded down flat on the wings 8 and 9, as in Fig. 3. By finger pressure on the outside of the strip 13, the flange is then stuck permanently to these wings, and thereby the envelop is sealed for transmission to the censor. Then, when the envelop reaches the censor, he opens it by inserting a knife-blade or the like between the flange and the strip and thereby severing them from each other along the line of the perforations 15. By thus opening the envelop, he Permanently exposes the legend or equivalent marking on the flange 10, as in Fig. 4. Then the censor takes out the letter, and, after due examination or treatment, puts it back in again. Then he tears off the strip from the flap, along the line of the perforations 14, leaving the envelop in the condition shown in Fig. 5. Then he moistens and sticks down the flap, as in Fig. 6, which shows the missive ready for transmission to its proper address.

I claim as my invention- An envelop of the specified class, comprising a flat pocket, a closing flap united.

therewith and gummed on the inside, a nonthe flange is adapted to be folded underand adhesive demarked strip separably united against the strip and in that position to be With the free margin of the flap, and'a re stuck to the back side of the pocket and 10 movable flange Which is not Wider than the covered by the strip.

strip, is distinctively marked on the inside, Witness my signature at Omaha, Negnrnmed on the outside and flexibly united braska, September 7th, 191 wlth the free margin of the strip; whereby HARRY B. MAXWELL.
