ARNOLIh'DELFFS, OF NATIONAL SOLDIERS HOME, TENNESSEE.'

ENVELOP Specification of Letters Patent.

Patented Nov. 19,1912.

7 Application filed July 27, 1911'. Serial No. 640,760.

To all whom it may concern:

Be it known that I, ARNOLD DELrrs, a citizen of the United States, residingat National Soldiers Home, in the county of Washington and State of Tennessee, have invented a certain new and useful Improve- -ment in Envelops, of which the following is a specification. 7

My invention relates to new and useful improvements in envelops, and has for its object to provide a device of this character which cannot be opened without detection.

A further object of the invention is to produce an envelop which, after being opened byan authorized person or the one to whom it is addressed, a closing flap will remain which when folded over the envelop will retain the contents therein.

A further object of the invention is to produce an envelop in which-the inclosing flap folds over on to the face of the envelop which'is to receive the address, so that after said address has been written, should anyone attempt to open the envelop and the flap be loosened, it would be a very difficult matter for said flap to be again placed in the same position as before, so that the lines of the writing upon the flap would aline with that part of the writing upon the body of the envelop.

In accomplishing the above named objects, I provide an inclosing flap which when sealed covers one entire face and a portion of the opposite face of the envelop, and this flap is provided with two sets of perforations, one set of which will lie on one face of the envelop and the other set on the other face thereof. One set of perforations permits the envelop to be opened and retain a flap to close the open end of the envelop while the other set will permit the inclosing flap to be torn apart should any one attempt to fraudulently open the envelop.

With these ends in view, this invention consists in the details of construction and combination of' elements hereinafter set forth and then specifically designated by the claims.

In order that those-skilled in the art to by letter to the accompanying drawing form- 'ing a part of this specification, in which-- Figure 1, shows the blank from which 1 the envelop is produced- Fig. .2 shows the envelop open, ready to receive the letter. Fig. 3, a face view of the envelop, sealed, with the name written thereon. Fig. 4, a face view of the opposite face of the envelop; and Fig. 5, an enlarged transverse,-

sectional view, showing the flap out of contact with the face of the envelop, prior to sealing.

In carrying out my invention as here cmbodied, 2 and 3 represent the body portions of the envelop which are folded together along the dotted lines 4 and are held in place by the end flaps 5 which fold inward on the dotted lines 6 over the body port-ion 3; these end flaps being secured to the body portion 3 by suitable adhesive substance 7.

8. denotes the inclosing flap formed with the body portion 2 and adapted to be folded along the dotted line 9. The inclosing flap is divided into three parts, 10, 11 and 12, the part 10 being divided from the part 11 by the perforations 13 in one or more rows, and

the said part 10 has no adhesive material thereon and forms the retaining flap. The parts 11 and 12 are divided from one another on an imaginary line indicated by the dotted line 14:, at which'point the'inclosing flap folds so that one part liesover one face of the envelop and the other part over'the other face thereof. The part 12 is provided with the transverse perforations 15 which may be in one or more rows and which prevent the inclosing flap from being steamed and opened without tearing. The parts 11 and 12 are covered with an adhesive material 16. After the letter or other objects are placed in the pocket 17 of the envelop, the inclosing flap is folded over the open end until it overlies the body portion 3, the part 11 adhering thereto inthe ordinary manner. The part 12 of the inclosing flap is then folded along the dotted line 14 and is fastened by the adhesive material to the body portion 2. After the envelop has been sealed, the name is written on the sections 2 and 12, so that in writing the address a portion thereof will be upon the body of the envelop while other portions are upon the part- 12 of the flap.

Should any one attempt to open the envelop bysteaming the same, the adhesive the adhesive material has; become softenedand an attempt is made to withdraw the inclosing flap, said inelosing flap will in all the envelop has been tampered with.

After the envelop has reached the person to whom it is addressed, said addressee can readily open the envelop by inserting a pencil, letter opener or other object'between the part 10 of the inelosing flap and the body of the envelop, causing the part 10 or remaining llap to tear from the part 11 along the row of perforations 13, then by turning back the remaining flap, the contents may be removed, and when said contents are replaced in the envelop, this flap will prevent their accidental removal.

Of course I do not wish to be limited to the exact details of construction as here shown, as these may be varied wiuhin the limits of the appended claims without departing from the spirit of the invention.

I'Iaving thus fully described my invention, what I claim as new and useful, is-

1. An envelop consisting of a bod y and an inclosing flap, said inelosing flap being divided into three sections by a row of perforations, and a fold, the endmost section having perforations therein, the two endmost sections being covered with an adhe' sive material, leaving the section adjacent the body without an adhesive material to produce zi lion-sealing inclosing flap.

5!. An envelop comprising a body portion and an inclosing flap, said inclosing flap being of sufficient. length to over-lie one face of the envelop terminating at a point below the post mark and stan'iping space so that the address will cross the end of the inclosing flap and be upon both the envelop and the inclosing flap, said inclosing flap being divided into three sections by a row of perforations and a fold, the endmost sections having perforations therein, the two endmost sections being covered with an adhesive material leaving the section adjacent the body without adhesive material to produce a non-sealing inc-losing flap.

In testimony whereof, I have hereunto afiixed my signature in the presence of two subscribing witnesses.

ARNOLD DELFFS.
