COMBINED ENVEL OP AND LETTER-SHEET.

Specification of Letters Patent.

.latented May 6, 1908.

Application filed November 1, 1907.- Serial it. scares.

To all whom it may concem:

.Be it known that I, ISRAEL L. GREENBLAT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Combined E11- velops and Letter-Sheets, of which the following is a specification.

This invention relates to a combined envelop and letter sheet and has for its object to'produce an article of this character pro' wra pad and folded u on the sheet and suc.-

y transmitted t rough the mails with- 1 case out danger of the article becoming disengaged from itswrapper and lost from the enveiop.

To these ends the invention'resides in the novel construction of envelops hereinafter fully described and claimed.

in the drawings, Figure 1 represents a lan view of my improved envelop in its unfo ded tising page of the envelop folded and the envelop ready to be sealed, and Fig. 3 is aview of the envelop sealed.

As illustrated in the drawings my improved envelop is constructed. of a single piece of paper out to the required length and width to orm a plurality of faces. The front face 1 is provided with the ordinary sealing flap 2 a'ving the gummed'surface 3 and the side flaps 4. The front face 1 is suitably creased as at 5 and is provided with a rear face 6 which in turn is provided w th the crease 7 from which depends the letter or advertising page 8 of the envelop. This advertising age 8 may consist of any suitable number of aces 9 of lesser width than the front and rear.

faces 1 and 6 of' the envelo proper, and are rovided with a plurality-of creases 9 whereliy they are adapted to be folded one upon the other, as clearly shown in Fig. 2 of the drawings. The side flaps 4 of the front and rear faces of the envelop are slit at 10 at a po nt coinciding with the crease 7 of the rear face of the envelop. The letter or advertise ing page is also provided withside flaps 1 1,

' easil which are ada ted to be folded over the face of the page and to secure any mailable article within the sheet and securedly retain the ar ticle when the sheet is folded within the .en-

velop when the letter is to-be disposed with the envelo shown in ig. 2 of thedrawings. faces of the side flaps 4 of the front face of the envelop is suitably gurnmed so'as to provide in a position to be sealed, as The inner a sealing means whereby the rear face 6 may be secured to the front face of theenvelop.

When a letter is written upon the letter page 8 of the envelop the flaps 11' are folded over the face of the page and the page is then folded upon its creases 9 until t ey are de osited against the inner surface of the rear folded over the faces 8 as illustrated in' 2, and the front and rear faces are then bent upon the crease 5 and are secured together by the ummed surface upon the side flaps 4, the sealing flap is then brought into the po' ace 6 of the envelop. The flaps 4 arethen.

sition shown in Fig. 3 of the drawings and the envelop thus completed.

. To open the envelop one side and top of the envelop is cut and the letter or advertisj-' ing age 8 thus severed from-the remainder of t e envelop and its withdrawal easily effected.

B the construction above described it will he readily seen that I'have provided an envelop of extremely simple formation, one in which a letter or advertising age is effectively provided and sealed an whieh is removed from the remainder of the enve 0 when so desired. i

It will be noted that'the fold lines for the flaps which extend along the opposite sides result being that a er folding the letter sheet jfliortion of the blank and turning in the side aps, the ackage thus far formed will lie within an between the dplanes of the fold lines which define the en flaps of the'body' portions or frontand ba'ck'of the-envelop, as shown in Fig. 1, enablin the fla s 4 to. be folded over the ends of the fo ded letter sheet. This is productive of a neat package in envelop form.
