A vide an envelop having a tearing section reinforced to provide a uniting member, the structure of which is unbroken; to provide in an envelop of the character mentioned means for preventing theintroduction within the tearing area, of'the letter or inclosure when deposited in the envelop; and to provide means of the character mentioned readily and cheaply applicable to envelops constructed in accordance withv the present invention.

One embodiment of the present invention is shown in theaccompanying drawings, in which- Figure 1 is a view of an envelop blank having attached thereto a reinforcing strip constructed and arranged in accordance with the present invention; Fig. 2 is a similar view of a modified form, showing an end fragment of the envelop having said reinforcing strip, the body of the envelop 'bein shown as scored and perforated to facilltate the parting of the tearing strip; Fig. 3 is a similar View of a modilied form, wherein the reinforcing strip is.shown as applied to the flap and body portion of the envelop blank; Fig. 4 is a detail View, on an enlarged scale, showing in section an end fragment of an envelop constructed and arranged in accordance with the construction shown in Fig. l, the section being taken as on the line 4-4 in said figure; Fig. 5 is a similar view of the construction shown in /Fig 2, the section being taken as on the line 5 5 in said Fig. 2; Fig. 6 is a similar view of the construction shown in Fig. 3, the section being taken as on the line (5*6 in said Fig. 3.

As seen in the accompanying drawings, the envelop blank 11 is of conventional construction. The sheet from which it is cut is previously provided with a suitable number of lines of perforations 12, so located on the sheet that when the blank 11 is cut, the line of perforations l2 is spaced from Specification of Letters Patent.

shown in Fig. 1 of the drawings. The -se'ctions of the flap 13 in which the perfora tions 12 are placed are by this means partially severed. The texture of the material is such, however, that in. the ordinary service to which the envelop is put, ythe material becomes broken, and there exists the danger of the envelop breaking. at this point to permit the withdrawal from, or loss .of the contents of, said envelop.`

y *Patented-May 26,1914.

the body of the envelop Asubstantially as It is to avoid the severance of the sections of thel flap 13, to which attention is above drawn, that I attach to the 'lap 13 and to the inner surface thereof, a reinforcing strip 14, constructed of any suitable material, such as a close-woven paper, the weave of the paper providing pliability conjoined with tensile strengt The reinforcing strip is attached to the flap 13 lby a suitable adhesive. The stri 14 is furnished with a gummed or coate section 15, the width of which is slightly less than the width between the vertical edge of the body of the envelop and the line of perforations 12.

When the sheet from which the blanks,

such as designated by the numeral 11 in the drawings, are cut, has been provided with the pcrforations 12 and the strips 14, the blanks are cut therefrom as though the strips did not exist. When the edges of the flaps of the enve op have been gummed and the blank is fold d to form the envelop of commerce, the coated section 15 is moistened so that it adheres to the inner face of the body portion 11. The adheredportions held by the coated section 15 prevent the intrusion of the contents of the envelop beyond the line of tear or separationprovided by the perforations 12. When thus con.- structed, the envelops are handled in the usual manner. It will be noted, however, that the nclosure of the envelop cannot pass beyond the line of perforations 12.

I/Vhen the envelop is to be now opened, the' end portion having the gummed section 15 is torn from the body of the envelop, the line of tear being controlled by the weakened texture in which the line of perforations 12 is formed.

In certain forms of envelops, I prefer to add a second line of perforations 16, which perforations in the completed envelop are formed in the body of the blank 11, and

flaps 17 and 18 as seen best in Fig. 2 of the loo drawings. When now the envelop is folded,

the coated section will unite the portions of the body of the blank 11 between the line of perforations 16 and the edge of said body and the coated section of the Hap 13.

When thereafter the rigid edge thus formed by uniting the coated section and the corresponding portion of the body of the blank, is torn from the envelop, the coinciding lines of perforations 12 and 1G reduce the resistance of the material to the tearing effort.

and preferably on the portion thereof Vwhich f is attached to the body of the blank 11. It will be seen that when thus constructed, the united sections of the flap 13 and the body of the blank 11, between the? edge of the folded envelop and the lines of perforations 12 and 16, constitutes a rigid edge, which may be ripped or torn from the body of the envelop. It will further'be seen that the mesma united portions within the envelop, of the strip 19, will prevent the intrusion .of the contents of the envelop into the tearing area. v Having thus described my invention, I claim as new and desire to secure by Letters Patent A blank of the character described having a rectangular body portion and flaps extending therefrom and provided with a plurality of lines of perforations, said lines being disped parallel to the edge of the body portion of saidenvclop and equally distant therefrom and on opposite sides thereof to coincide when the blank is folded;

and 4an imperforate reinforcing strip to coveil said lines of'perforations and extendlng at both sides thereof, sald strip having an adhesive surface extending from the edgel of the body portieri to one of the lines of perfor-ations.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
