ENVELOP.

Specification of Letters Patent.

Patented July 19, 11.921.

Application filed May 22, 1919. Serial No. 298,998.

To all whom it may concern:

Be it known that I, Jnnno'm) P. DE VAUGHN, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented a new and Improved Envelop, of which the following is a full, clear, and exact description.

This invention relates to envelops, and has reference more particularly to an envelop used in mailing correspondence. and for other purposes, and comprising a body having overlapped flaps, and a closing flap adapted to be inserted underneath the overlapped flaps, the closing flap presenting a surface for an address or other inscription, the arrangement being such that the address is visible when the closing flap is in position under the other flaps. The invention also relates to an envelop having flaps overlapped and secured together, and a closing flap adapted to bear an inscription and to be inserted under the first flaps, which are provided with an opening to render the inscription visible when the envelop is closed.

The object of the invention is to provide a simple and durable envelop which can be inexpensively produced, which is capable of repeated use until worn out, and upon which the address or other inscription can be readi] y produced by means of a typewriting machine or otherwise.

A further object of the invention is to provide an envelop easily manipulated in opening and closing the same, in which the contents are securely held although the envelop is not sealed, and which may have two addresses or other inscriptions permanently applied thereto although one only at a time is visible when the envelop is in use.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a plan view of the blank from which the envelop is formed;

Fig. 2 is a plan view of the blank, showing the end flaps folded into position and secured together;

Fig. 3 is a transverse section on the line 3-3 of Fig. 2;

Fig. 4 is a plan view of the completed and closed envelop ready for use; and

Fig. 5 is a transverse section on the line 5--5 of Fig. 4.

Before proceeding to a more detailed explanation of my invention, it should be clearly understood that the envelop can be manufactured in the usual manner, from paper or other material adapted for the purpose, and in various shapes and sizes. While it is capable of general and ordinary use it is of particular value in the offices of railroads or similar industries in which large quantities of envelops of all sizes and kinds are used, such use in many instances aggregating millions annually. It is designed primarily for so-called shuttle use. That is, for sending back and forth between two specific oflices or destinations, between which there is a continuous inter change of mail or other corres iiondence. This envelop can be used for such purposes repeatedly until it is worn out. It bears, permanently inscribed thereon, both addresses, one or the other of which is positioned to be visible according to the intended destination in question.

My envelop serve to replace those at pres ent in use, bearing certain addresses printed or otherwise permanently inscribed thereon, which, after having been used once must be re-distributed empty before they can be used again. In this way a great saving is effected.

Referring more )articularly to the drawings, the envelop comprises a body section 10, having at each extremity a tapered end flap 1.1, terminating in an extension 12 havingparallel sides. One of the extensions 12 is provided with a gurnmed surface 13. Each. extension has formed therein an elongated opening 14 having rounded ends. These openings are similarly located and proportioned.

At the opposite, longitudinal edges of the body 10 are formed similar closing flaps 15, preferably tapered as 'is shown in Figs. 1 and 2.

In forming the envelop, the end flaps are folded inwardly and overlap. They are permanently secured together by means of the gummed surface of the one extension 12. The openings 1-l register as is shown in Fig. 2. The envelop is now ready for-use. Each of the closing flaps has delimited thereon an address space 16, preferably similar in form to the opening 1 1. The closing flaps are folded inwardly and inserted under the end flaps. When so positioned, the address spaces 16 Will register with the openings 14. The address 17, or other inscription is produced upon each closing flap, and this inscription will be visible through the open ings 14, according as the closing flap iunder or overlies the other closing flap.

In providing two permanent addresses in this way, the envelop can be used repeatedly in sending matter bank and forth between two destinations. In each case the proper and requisite closing flap is caused to overlie the other closing flap and conceal the address upon the latter.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent 1. An envelop comprising a body having overlapped flaps having registering openings when so overlapped, and a closing flap attached to said body and adapted to be insertedunderneath said first flaps, said closing flap presenting a surface for an address, said first-mentioned flaps being arranged to render said address-surface of said closing flap visible when said closing flap is in position underneath said registering openings.

2. An envelop comprising a body, end flaps attached thereto and inwardly folded and overlapped, the overlapping portions of said flaps being permanently secured together and having an opening through the overlapped portions, and closing flaps attached to said body, at opposite sides thereof, said closing flaps being adapted to be 'lolded and inserted under said end llaps and to bear an address visible through said open ing.

3. An envelop comprising a body, tapered end flaps attached thereto and inwardly folded and overlapped, the overlapped portions of said flaps being senured together permanently, and having registering openings therethrough, and closing (laps a l'ta 'hed to said body at opposite sides thereof, l\otween said end flaps, said closing flaps being adapted to be folded and inserted under said end flaps, and each. bearing a l lll'lllllllvllll address-inseription, said address-inst'ription of the uppermost closing flap being visible through said openings.

4:. An envelop of the character spwilied, and comprising a body having end llaps overlapped and permanently secured together, said end flaps haying elongated registering openings in their overlap nal portiod-a. and closing flaps at the upper and lower ends of the body a l:1 ted to be inserieil beneath said end flaps and overlapped and to over or underlie each other when so inserted, said closing flaps having (:(n'rosponding areas adapted for permanent insertion thereon oi permanent addresses, emh oi said areas adapted to be visible through the aforesaid registering OIKIllHgS, according as one closing Hap under or overlies the other closing flap.
