SPECIFICATION forming part of Letters Patent No. 670,186, dated March 19, 1901 Application filed November 14,1900. Serial No. 36,455. No model.)

To rtZZ whom, it may concern.-

Be it known that I, ALGIE PERRY, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have in- 5 vented certain new and useful Improvements in Envelope, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

[ My invention relates to an envelop for open or third and fourth class matter, the object of the invention being to provide an envelop of the class named that is simple in construction, substantial, and at the same time inexr pensive of manufacture, being constructed from a single blank in which the closing means is embodied.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Figure I is a view of the rear side of my improved envelop in closed condition. Fig. II is a view of the rear side of the envelop in open condition. Fig. III is a view of the blank from which the envelop is formed.

1 designates the front of the envelop, which is the central part of the blank seen in Fig. III. At each end of the front 1 are end flaps 2, provided with slits 3, (see Fig. III,) that 0 when the end flaps are brought together provide a slot 4;. (See Fig. 11.) At the lower side of the front 1 is a lower flap 5, provided with a tongue 6. The end flaps 2 and the lower flap 5 are designed to be gummed at their edges and secured together in the usual manner, leaving the tongue 6 free.

7 is the top or closing flap, provided with a slot 8, the position of which is such that when the flap 7 is folded onto the back of. the envelop the slot 8 will register with the slot 4.

In the use of the envelop the contents are first placed therein while the flap 7 is in the raised position seen in Fig. I, and the flap 7 is then folded onto the back of the envelop, so that the slots 4 and 8 will register. The tongue 6 is then inserted first through the slot Sin the top flap and next through the slot 4, its free end passing to the interior of the envelop, where it rests between the inside of the back of the envelop and-the contents held thereby. As the contents of the envelop press against the tongue 6 it is obvious that the tongue is always held tightly in place, and the greater the bulk of contents the tighter the pressure exerted against the tongue and the more firmly it is held.

I claim as my invention- An envelop constructed with end flaps having a slot extending across their overlapping and sealed edges, a bottom flap sealed to the end flaps and having a tongue, and a top flap having a slot located over the slot of the end flaps and extending beneath the tongue; the tongue being inserted through the slots for securing the top flap to the end flaps.

ALGIE PERRY.

In presence of E. S. KNIGHT, M. P. SMITH.
