Specification of iietters Patent.

Application filed February 17, 1915. Serial No. 8,805. I

To all whom it may concern:

Be it known that I, ANTONIO DAcos'riNo, a citizen of the United States of America, residing'at Utica, in thecounty of Oneida and State of New York, have invented certain new and useful Improvements in Safety-Envelops; and I do hereby declare the following to be a full, clear, and exact 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 safety envelops, the object of the same being to provide an envelop of simple construction which cannotbe opened Without mutilating the paper and indicating that the envelop has been tampered with by an unauthorized person.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which Fi ure 1 is a plan view of the blank from which the envelop is made looking at the inner side of the blank, Fig. 2 is a view looking at the face side of the envelop with the sealing flap unattached or unsealed, Fig. 3 is a fragmentary section of the envelop in sealed condition and before the stamp has been ap' plied, and Fig. 4 is asectional view taken on the line 4-4 of Fig. 3 and made on a larger scale and showing the stamp attached to theenvelop.

Referring to the drawing, the numeral 1 ing flap 9 provided with an adhesive substance 10 extending around the outer edge thereof and said flap being slightly offset from the center of the body portion 1 and having a curved line 11 on one side and a compound curved line 12 upon the other side, while the end 13 is plain.

The face portion 14 of'the envelop is rectangular in form and is of substantially the same size and form as thebody portion 1 of the envelop. Upon the right hand upper corner of the face portion 14 when folded is a rectangular opening 15 having a V-shaped projection 16 extending from the inner edge of the openlng. The face portion 14 is also provided with adhesive substance 17 on the V inner face thereof around the edges.

In folding the envelop, the flap 2 is first folded on the dotted lineIa against the body portion 1. The flap 5 is then folded upon Y hesive material 10 to the edges of the flaps 2 and -lVhen the letter or missive d is in serted 1n the envelop, the face portion 14is folded along the dotted line 6, thus bringing the opening 15 over a portion of the side flap 5 and over a portlon of the misslve d. When the stamp f in Fig. 4 is attached to the envelop and disposed over the opening 15,a

portion of the stamp will be connected to the missive d, to the tongue 16, and to the margi- V nal portion of the opening 15, as well as to a portlon of the flap :5. The curved line 6 of the flap 5 extends diagonally across underneath the opening 15, as shown in Fig. 3, when the envelop is folded and ready to be mailed.

From the foregoing it will be obvious that the contents of the envelop cannot be removed for inspection without mutilating the envelop.

Various changes may be made in the details of construction without departing from he spiritand'scope of the invention as defined in the claims.

What is claimedisz- I A safety envelop having a body, a side flap, having a straight upper edge and an inclined lower edge, 'a smaller side ,flap

formed on the opposite side of the body, said smaller side flap having a curved upper edge and an inclined lower edge, a bottom sealing flap having adheslve materlal around the edges thereof, and aface portion substantially rectangular in form provided with an opening somewhat smaller than a postage stamp at the right hand upper corner, said opening being provided with an extended tongue and said face portion folded u against the side and bottom flap, a portion of In testimony whereof I afiix my signature the contents of the envelop will be exposed in presence of two witnesses.

through the opening so that when a postzwe 7 stamp is attached thereto it will adhere to 7 ANTONIO D AGOSTINO' the contents to one of the side flaps as well Witnesses:

as the face portion, thereby preventing the CHESTER DAVIS,

same from being opened without detection. 7 S. JV. HITCHCOCK.
