JOSEPH SAWDON, OF QUINCY, ILLINOIS.

DUPLEX EirvELor.

" To all whom it may concern:

Be it. known that I, JOSEPH SAWDON, a

\ citizen of the United tates of America, and

resident of Quincy, county of Adams and State oflllinois, have invented a certain new and useful Improvement in Duplex Envelops, of which the following is,a specification.

This invention contemplates a duplex envelop having a relatively small compartment to hold .a letter, and a relatively large T compartment to hold printed matter, so that V -ment being left open.

the two things, although subject to different postal rates, will be practically inclosed'by one and the same envelop, the smaller compartment being sealed when transmitted through the mails, and the larger compart- The object of the invention, therefore, is to provide an improved construction and ,arrangement whereby things which are ordinarily subject to different postal rates, and which are usually sent in separate envelops or wrappers, may be inclosed in practically one and the same envelop, so the two things may not become separated and will arrive at their destination together. I

It is also an object to provide certain details and features of construction and combinations tending to increase the general efiiciency and desirability of a duplex envelop of this.. .particular character.

To the foregoing-land other useful ends, the invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings Figure .1 is a front elevation of aduplex envelop embodying the principles of the in-' vention, showing a portion-of the front wall broken away to show the construction.

Fig. 2 is an enlarged vertical section on line 22 in Fig 1. Fig. 3 is a perspective of the envelop shown in Fig. 1, but without the means to form the relatively small compartment.

As thus illustrated, and referring to Figs. 1 to 4 inclusive, the invention comprises an Specification 61 Letters Patent. P t t May 20, 9 I Application filed January 21, 1918. Serial No. 213,028.

envelop 1 of any suitable form or character,

having one end thereof pr vided with a flap 2 to be secured in place by t e usual fastening device, or by any suitable means. The

front wall of the envelop is provided with a longitudinal slot 3, and with printed. lines 4, these lines and said slot inclosinga rectangular area on the front of the envelop.

A sheet of paper 5 is provided with end 7 flaps 6, and with an upper flap 7 and a lower flap 8, all of these flaps being preferably provided with mucila in place on said envel p. 'This is done by inserting the sheet of p aper5 inside of the.

envelop 1, and by sticking the flaps 6 and 8 to the inner surface of the front walls of said envelop, and by bending down the flap 7 and inserting this flap outwardly through the slot 3. All adhesive strip of paper 9 is then applied to the inner upper edge of the sheet 5, and to the inner surface of. the front Wall of the envelop 1, whereby a pocket or compartment is formed inside of said envelop, which can be entered by raising the flap 7i and inserting the letter or other article downward through the slot stood. The flap 7 is then folded downward and moistenedand caused to adhere to the" e for securing them in a manner that will be readily under-.

slot 3 and thereby;

small compartmentgj' flo inserted in the envelop 1, and the flap-2 is then secured in place by the fastening device,

but not sealed. In this way, the letter inserted in the smaller compartment is sealed, and the proper postage is then applied .at 10, while a stamp for theproper'postage is applied at 11 for the contents of the larger compartment. In this way, the two things which are subject'to diiferent postal rates, and which are ordinarily sent in separate envelop's, closed in one and thes I so segregated from eachother that the postal laws are. com mailbing sealed, w

ile the third-class matter is left open .or-aeces ible in the larger 1 But the two things are inseparable, and will arrive at their destina 11o compartment.

tion at the same time and will thus be presented to the addresses at the same-time and or mailed separately, are really ine envelop, but are m lied with, the: first-cla$s f together, practically, of course, in one and the same envelop.

The address can be placed on the envelop in any suitable position, but is preferably applied to the rectangular area inclosed by the slot 3 and the lines 4, while the return card of the addresser may appear at the ceding figures, but in this case the front- Wall of the envelop 12 is provided with a -vertical slot 13, and with an opening 14 to expose the address on the latter, so'that it is not necessary to address the envelop. The

sheet of paper to provide the relatively small compartment has the top and bottom flaps 15 and 16 secured to the inner surface of the front wall of the envelop 12 andhas the end flap 17 secured in place in the same way, but

the other end flap 18 is inserted outward.

through the vertical slot 13, and then moistened and caused to adhere to the front surface of the envelop 12 when it is desired to seal the letter inclosed in this relatively small compartment. With this construction, therefore, the letter compartment is left open at the end, whereas in Figs. 1- to 4,

inclusive, the letter compartment is left open at the upper edge or top thereof.

' In Figs. 6, 7 and 8, the constructioncomprises an envelop 19 to inclose 'printedmab ter or other inferior class 'mail matter, and

may be constructed like the envelop previously described. In this case, however, the

front wall of said envelop 19 is not proj vided with a slot, and the relatively small compartment for the letter or first-class mail matter is formed by a smaller envelop 20 which has its 'rear side lued or otherwise secured to the front; sur ace of the envelop 19, but with the flap 21 thereof left loose, so that the letter can be; inserted in this envelop 20 inthe usual manner. As shown,

saidenvelop 20 has an opening 22 for the purpose of exposing the address on the letter, so that it is'not necessaryto address the envelop. After the letter is inserted in the envelop 20,'the flap, 21 is then. moistened and then caused to adhere to the outer surface of the envelop 19, thereby'sealing the letter; Itis obvious," therefore, that the in vention 'may'be used in various ways, and

in various forms of envelops. 'The form shown in Figs.'6 to 8, inclusive, involves the construction of two complete envelops, which are ',afterward fastened together, so that more paper orother material would be employed in the manufacture of envelops of this" form than would be necessary 1n the envelops shown-in Figs. 1 to 5, inclumosses .sive. Preferably, as shown,,' the smaller compartment is outlined upon the face of the envelop, and this is true of Figs. 1, 5 and 6, as in Figs. 1 and 5 the smaller compartment is outlined by the rinted lines on the face ,of the envelop, wh1le in Fig. 6 the smaller compartment is outlined b theedges of the small r envelop 20, w ereby the two' compartments are each well defined in the- Also, in each .of .the different structure. forms of-th'e invention shown and described, the smaller compartment has a sealing flap which may be sealed, by-causing it to adhere flatwise upon the-face of the"envelop-that is to say, upon the main'front' wall of the larger envelop. Ordinarily, things subject .to diflerent postal rates are sent in 'sepa-' rate envelops, but it-is a matter ofcommorL' 'knowledge that the method is productive y of considerable trouble and annoyance, for

the matter which is subject to inferior postal rates usually arrives some time after the envelop containing the letter. Also, the two thin s arriving separately, one or the other is o ten lost or mislaid. With the construction shown and described however, the letter and the printed matter, or matter subject to a less postage, will always arrive together tically one, and the same envelop, but'in a and will be handed to the addressee in pracmanner that complies with the postalflaws, I

one being sealed and the other unsealed, and

each having its ownproper postage. The L;

invention, therefore, is hot limited to the.

exact construction shown and-described.'

It is obvious that the larger or-main envelop can be constructed in different ways, and'in Fig. 5 the construction mayinvolve' i an inner strip of paper 23, similar to the strip of paper 9 shown in Fig. 1, whichmay' ,be employed t o secure the inner sheet of paper to the front wall of the main or larger envelop. Furthermore, and while for the urpose of illustration, to .show how the invention may be used, the larger envelop, has been described ascontaining printed matter, it will be understood that it may contain anything else that,can be sent through the malls forla'ss postage than the letter. In any event, though, as previously explained, and as shown and described, the invention comprises a plurality of separate compartments, but each compartment may be of any suitable character, more espe ciall the one for the printed matter, as this arger compartment, which is intended to contain or hold various things, ma be of any suitable form or character, suc as the various envelops 'or wrappers employed in sending the newspapers or other printed matter, or any other' desired article which may be transmitted through the mails.

in each case the small compartment is on the front of the large compartment, the rectended to be sealed after the insertionof aletter-therein, and a relatively large compartment arranged back of the small compartment, so that the small compartment is onthe front of the large compartmenaand which large compartment is adapted to be left open or unsealed at the back of the-envelop after the inclosure of printed matter or an article therein, the envelop having a.

single addressing space for both compartments on the face of the small compartment, the two compartments being permanently united in one unitary structure, with the small compartment on the face of the main envelop, so that the two compartments may contain things which are subject to different postalrates, the contents of the larger compartment being subject to inspection and removal without opening the smaller or sealed compartment, whereby the two things will not become separated and will be delivered as a single piece of mail to the addressee, and

a with the total postage all on; the front of the a loose flap, said envelo havinga slot in its envelop but separately applied to each compartment,- g

2. A stucture as s ecified in claim 1, said relatively small compartment'being formed by a sheet appliedto the inner surface of the front wall of the envelop, said sheet having front wall through WlllCh saidt flap projects outwardly, so that after the letter is inserted through said slot into the relatively small.

compartment the flap ma then be sealed by causlng it to adhereto t e outer surface of the envelo said small compartment being disposed a jacent the lower edge of the large compartment, and an inner retainin'g str p back of saidfla'p to secure the sheet to the front wall of the,'envelop.

3. A- duplex envelop comprising a plural;

' ity of compartments for diflerent articles, or

- the unsealed compartment being removable without '0 ening the sealed compartment, whereby t ings subject to different postal rates occupy difi'ere t separate compartments v in one and the same envelop structure, the

' entire sealed compartment and its flap being on the face of the main envelop, so that one address applied to the sealed compartment is suflicient for both kinds of mail matter,

and with the total postage all on the front of )0.

the envelop but separately applied to each compartment.

4. A' duplex envelo comprising a relatively large rectangu ar compartment for printed matter, or for other mail matter less than first class, and a relatively small letter compartment on the front of said large compartment, so that one address applied to the small compartment is sufiicient for both kinds of mail matter, with a flap on the rear side or back of the envelop for accessibly closing the large compartment, and a flap on the face or front side of the envelop for sealing the small compartment, the rectangular outline of the small compartment appearing on the face of the envelop.v I
