Specification of Ltters Patent. i Patented Aug". 24; 19115.

Application filed February 9, 1915. serial No. 7913./

mattei', and the main object thereof is to l provide a sheet of such form as to adaptit for use as two distinct envelops for letters, as a return envelop combined with the outgoing envelop, and as a wrapper for news'- pa ers, etc.

y invention` is fully described in thejfoI- lowing specification, of which the accom-l panying drawings form a. part, vin which llike reference characters refer to like parts in each of the views, and in which 'Figure 1 isa view of the blank struck from suitable material; Fig. -2 is a perspective ,View of a, step in the folding thereof withA a contained return envelop; Fig. 3 is a 25. back vilewthereof, closed, and showing oneA method of opening so as not to mutilate the return envelop; Fig. 4 is an enlarged section taken on the line 44 of Fig. 3; Fig. 5 is a perspective view of the forni shown in Fig.

'0 3, inthe operation of unfolding after slitting the bottom and ends of the outer envelop; Fig. 6 is a view of one of the two single envelops rendered possible by my blank; Fig. 7 isa plan view .of the blank in the operation of preparing it vfor usel as a Wrapper for newspapers; and Fig.. 8 is a View thereofin use.

A the drawings forming a. part of this application I have shown a blank 9 compris-- o ing a central portion 10, address portions 11 and 12 connected to opposite sides thereof, endiaps 11u and sealing .flap 11" ,for the portion 11, and end flaps 12 and sealing Hap 12b for the portion 12, the central portion i5 being longitudinally scored or perforated along the center thereof at 10". .Scored o r perforated lines 13 are provided between the rtion 11 and its end flaps 11, and similar iines 14 are provided between the portion 12 5 and its end aps y12; a scored orv perforated line 15 is provided between the portio 10 and fthe portion 12,'and a similar line..` etween'the, portion 12. and its sealing flap l2,

as shown at 16.L The sealing iiaps 11b and t l2" are gummed on their inner sides, along the edges thereof,'as shown at 17 and 18,

these being the only gumined parts.

When itis desired'to use the blank for ordinary envelops, said blank is torn'along the line 10", :the resulting portion of the central portion 10 then becoming the bottom flap of the respective address portion 11 or 12. The lowerflap, on either part, may then be turned inwardly, the end iaps turned thereover, the guniming of the sealing Hap moistened and this flap pressed upon the'4 lower and end flaps, thus resulting" intwo ordinary envelops, it .being understood that the contents of the envelope;l are first inserted'before sealing, this'ordinary type of envelop being shown in Fig. 6.

When the blank is to be usedfor wrapping newspapers, the end flaps are torn from the address portions, thus resulting in a long anl relatively narrow strip having gumm'ed en s.

In Figs. 2 to 5, inclusive, I have shown the blank Aused with a return' envelop and in which use the end flaps 11 are turned in? wardly on the address portion 11, followed by the sealing flap 11? but with the gumming unmoistened; the address portion 11, with these fiaps folded thereon, is then turned over on the central portion 10, on the line 20, and the central portion 10, together with the parts thereon, turned over on the line 15 upon the address portion 12 the letter .is now` placed between the portions 10 and 12, the fiapsl. turned inwardly over the portion 10, and followed by the sealing flap 12" ,with the gum moistened' and, when the gunnned guln is pressed against the flaps 12?l and portion 10, the original envelop is sealed.

When the addressee opens the letter he tears along the lines 14, 16, and lll, or cuts with a suitable blade, thus separating the iaps 12 and 121 from the address Dortion 12 and permitting the contained letter to be removed, but he avoids cutting or tearing along the line 15 which would separate the portions 1() and 12.

When it is desired to use the return envelop, the detached iap 12Ir at one end is raised to give access to the perforated line. 10 and the portion-1.0 is torn into two parts, the half thereof adjacent the portion 12 still being connected therewith, `and the half adjacent the portion 11 still being connected therewith.

Because ofthe position and Width of the` guniniing on the flap 12b this flap is lonly pasted to theia1)s 12d and that half of the portion 10 adjacent the portion 12, and this division along the line 10L produces two elenients, one of which consists of the portion l2, adjacent' half ofthe portion 10, the sealing flap 12b pasted to said half portion, and the end flaps 12 pasted to said sealing the other eleinent comprises the address portion 11, the connected flaps 11 and ll, and the adjacent half of the portion 10, This element constitutes the return 4envelop and, after a return letter has been folded and placed upon the address portion 11, the liaps 1 1n are turned inwardly tliereover and over thev half portion l() previously turned over the letter, after which the sealing flap 11" inay have its gum inoistened and pressed down on the iaps 1.1l and half portion 10, and the envelop is ready for the mail.

1t ,will thus be seen that the original blank is adapted for a plurality of uses, and is of particular value where it is not feasible to carry a great range of different types of envelops and wrappers, as in relatively small business houses, but thel device possesses .great value as well to very large business establishments.

The blank iiiay be forined froni any de-- sii-ed material, of any size, and of any weight, and the configuration of the saine may be altered to ineet conditions as long as the 'relative positions of the several parts are not altered.v

Having fully described iny invention,.

tion on one side thereof provided with end flaps and a guniined sealing-flap, and an address portion oii the other side thereof provided with end iiaps and a gumined sealing Hap, the flaps of one address portion being folded upon the saine, said address portion -and iiaps being folded on said central por' tion, said central portion with" said address portion and flaps being folded on the other address portion, the end flaps ofsaid last nanied address portion being 'folded over said Acenti-al portion, iii-st address portion and flaps thereof, and the sealing flap of -said last nained address portion being,r then' folded over said last iiained address portion end liaps and` over said central iortion, the

.gum of said last nained sealing ap contactnained address portion, separated iaps, and

adjacent half of the central portion, when said central portion is divided along its weakened line, the 'adjacent half of the first named address portion and flaps being adapted to be folded inwardly to forni a return envelop. v

In testimony whereof` I have signed niy naine to this specification in the presence of two subscribing:r Witnesses. v JACOB MEREDITH CRULL.
