DAISY THOMSOM, OF PORTSMOUTH, OHIO.

ENVELOP.

T 0 all whom it may concem:

Be it known that I, DAISY TrioMsoM, a citizen of the United States, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Envelops; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in envelops.

The object of the invention is to provide an envelop constructed in such a manner as to prevent the same being opened or tampered with without detection.

IVith this object in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described hereinafter and particularly pointed out in the appended claims.

In the accompanying drawing, Figure 1 is a plan View of the front side of the envelop showing the same closed and sealed; Fig. 2 is a similar view of the envelop before the sealing flap is closed; Fig. 3 is a plan view of the inner side of the envelop showing the form and arrangement of the end flaps when folded in to close the ends of the envelop, and in position to receive the inner side of the front pieces; and Fig. I is a plan view of the blank from which the envelop is formed, showing in dotted lines where the parts are folded.

The envelop consists of a back piece, 1, and a front piece, the main portion of which consists of aflap, 2, formed integral with the lower edge of the back piece, 1, and by a short flap, 3, formed integral with the upper edge of the back piece, 1, as shown. The ends of the envelop are adapted to be closed by end flaps, L and 5, which are formed integral with the opposite ends of the back piece, 1, as shown. The end flap, at, is considerably shorter than the flap, 5, and is triangular in shape and adapted to be folded inwardly upon the inner side of the back piece. The end flap, 5, is substantially of triangular shape and is adapted to be secured at its outer end to the inner side of the flap, 4, as clearly shown in Fig. 3 of the drawing. The upper edge of the flap, 5, is notched inwardly as shown at 6, to facilitate Specification of Letters Patent.

Application filed August 24, 1908.

Serial No. 449,955.

the insertion and removal of a letter from he envelop when in a finished state.

The outer side of the end flaps, 4 and 5, are gummed and in forming the envelop said end flaps are folded inwardly over the inner side of the back iece, 1, and are secured together as herembefore described, and shown in Fig. 3 of the drawing. After the end flaps have thus been folded in and se cured, the gummed outer sides thereof are moistened and the lower flap, 2, of the front piece in the envelope is folded inwardly at the lower edge of the back piece, 1, and into engagement with the gummed outer sides of the end flaps, 4 and 5, thus securely fastening the front lower flap in position and C0111 pletin the envelop. The outer or upper end of the flap, 2, is preferably notched in as shown at 7 to facilitate the insertion and removal of a letter.

To close and seal the envelop, the upper short flap, 3, of the front piece of the envelop is now folded inwardly along the upper edge of the back piece, 1, and onto the upper edge of the lower flap, 2. The inner side of the upper flap 3, adjacent to its outer edge is gummed so that when said flap is folded inwardly onto the upper outer side ofthe lower flap, 2, the same may be sealed thereto. The flap, 3, is adapted to be further sealed to the flap 2 by the stamp which is to be pasted across the edge or end of the flap, 3, as indicated in Fig. 1 of the drawing.

In forming the envelop, the outer sideas shown at 8, which, when said edges are pasted down onto the end flaps, will form a closure which cannot be cutopen or tam pered with without detect-ion.

Further protection is afforded an envelop constructed in the manner described by reason of the fact that the sealed edges of the Various parts of the same are on the front side of the envelop, where any tampering therewith will be readily noticed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters-Patent, is:

An envelop comprising a back member having integrally formed end fiaps of different lengths adapted to be folded over said back member and to overlap each other near one corner of the envelop, a front member of less width than the back and formed integral with the lower edge of said back and adapted to be folded over and sealed to said end flaps and a seal flap formed integral With the upper edge of said back and adapted to be folded over said -front member and 4 p 5 sealed thereto in position to receive a stamp WVit'nesses:

In testimony whereof I have hereunto set my hand In presence of two subscribing wltnesses.
