Specification of Letters Patent.

Patented Sept. 15, 1908.

Application filed April 30, 1908. Serial No. 430,12.

.To'alhwhom it may-concern.

I Be It known that I, FRANCIS V. DON- NELLY, a citizen of the United States of -America, residing at Greensburg, in the iounty of Westmoreland and State of Pennsylvania, have invented certain new and useghl Improvements in Envelops, of which the gillowmg is a specification, reference being baa therein to the accompanying drawing.

1 Tina invention relates toenvelops, and the obyects of my invention are, first, to provide simple and inexpensive envelop having a ositive seal; second, to provide an envelop cannot be surreptitiously opened withoutdetectlon; third, to provide a strong and durable enyelop that can be advantageously ex ress companies and parties trans- ;nittmg va uable matter through the mails;

2 'andfourth, to obviate the necessity of using an adhesive material for sealing an envelop.

I attain theabove objects by a construciiofi that will be presently described, and then specifically pointed out in the appended claims.

Referring to the drawing forming a part of this specification, Figure 1 is a plan of apiece of paper from which my envelop is constructed, Fig. 2 is a cross sectional view of the envelop in a closed or sealed position,

Fig. 3 is a perspective view of the seal used in connection with the envelop, Fig. 4 is a p anof the envelop with the end llaps and sealing flap thereof open, Fig. 5 is a plan withone of the end flapsfolded, Fig. 6 is a 3 similar view with the sealing flap open, Fig. 7 ha similar view of the sealing flap closed, Fig. 8 is a similar view illustrating the envelop partially sealed, andFig. 9 is a similar view of the envelop sealed.

In the accompanying drawings, 1 desigmites the body of the envelop having end 2 and 3, a bottom flap 4 and a sealing flap 5,- these flaps being to (led upon dotted lines 6.

(5 ,The bottom flap 4 is provided with ad hesive material 7 to bcsccurcd to the body 1 ofthe envelop, and it'isforiued with a tongue 8 adapted to bel'olded upon the dotted lines .9" and 10. The adhesive material 7 is em- 5 loyed simply to secure the lower edge of the ottom flap 4 to the body of the envelop,

{whereby matter placed in the envelop cunliot extend to the lower edge of said envelop, the object of which willpresently appear. After 5 flisbottom flap 4 has been placed upon the fibdyl of the envelop, the end flaps 2 and 3 are folded inwardly upon the bottom nap 4, said end llaps being provided with slots 9 to dotted line 9, as illustrated in Figs. 5 and 6. The sealing flap 5 is adapted to be folded upon the end flaps 2 and 3, and is provided with a slot 11, to receive the tongue 8. The sealing flap 5 is formed with an auxiliary tongue 1 2 adapted to be folded upon the dotted line 1? said tongue lyingllush with the tongue 8, when-the same is bent downwardly, as best shown in Figs. 2 and S.

The tongues 8 and 12 are then bent to engage the front side of the envelop, as shown in. Fig. 9 of the drawings, and a seal is employed for securing said tongues to the lower edge of the envelop. This seal comprises an elliptical-shaped plate 14 having upwardly bent prongs 15. After the seal 18 placed in engagement with the lower edge of the on vcl p, it is bent upon the dotted lines 16, whereby the prongs 15 will engage in the envelop and become clenched therein. It will be impossible to remove the seal without ineasily detected.

By adhesively securing the bottom fiap to the body of the envelop, the matter carried within the envelop is prevented from being pierced by the lugs-15 of the seal.

I make my envelop of strong and durable paper or paperoid, and reserve the right to make the same of an desired size.

Having now descri ed my invention what I claim as new, is:-

1. An envelop comprising a body portion, end flaps, a bottom llap adapted to ave its lower edge adhesively secured to said body, a tongue carried by said bottom flap, a sealing flap, and an auxiliary tongue carried by said'sealing flap, said end flaps having slots formed therein adapted to receive the tongue of said bottom flap, said scaling flap having a slot formed therein adapted to receive the tongue of said bottom flap, said tongues being zid:ipted to be bent forward upon the lower front edge of said envelop, a plate i adapted to be bentin engagement with the E lower edge of said envelop, and prongs carricd-by said plate for engaging in said envelop, substantially as described.

2. An envelop com rising a body, a bottom fla ada )ted to old thereon, a tongue carried iy sai bottomflap,end fla isada ted receive the tongue 8 of the bottom flap 4. The tongue 8 is bent upwardly upon the juringthe envelop, and such injury can be i to fold upon said bottom flap, sai end p6 having slots formed therein to receive the the lower edge of said envelop and pierce said 10 tongue of said bottom fiap, a sealin flap tongues.

adapted to fold upon said end flaps, $8.] sea In testimony whereof I affix my signature in' fia having a slot formed therein to re in the presence of two witnesses.
