ENVELOPE Filed Sept. 4, 1928 INVENTOR ATTORNEY wlTNEss- Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE ENVELOPE Application filed September 4, 1928. Serial No. 303,790.

This invention more particularly relates to improvements in -envelopes and which embodies among other characteristics means for retaining the contents thereof against displacement.

An object of the invention comprehends a Window or sight opening through which the address of the recipient may be viewed and which will obviate the usual necessity of addressing envelopes.

Another' object of the invention conteniplates retaining elements adapted to engage the upper side of the envelope contents to coincide the address thereon with the window or sight opening.

With the above and other objects in view, the invention further consists in the following novel features and details of construction, to be hereinafter more fully described,

illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing Figure 1 is a front elevation of my improved type of envelop-e with the flaps and contents thereof shown in dotted lines.

Figure 2 is a vertical sectional view taken on line 2 2 of Figure 1.

Figure 3 is a diagrammatic plan view of the envelope in blank form.

Referring to the drawing in detail, where in like characters of reference denote correspending` parts, the reference character 10 indicates the front of an envelope having an elongated opening 11 therein cov-ered by a suitable transparent material, such as indicated at 12, to proviue a sight opening or window. Side iiaps 13 are then folded from the ends of the front 10 to dispose the end portions 14 thereof in juxtaposition.

The bottom flap 15 is then folded upon the under sides of the side iaps 13 and secured thereto by a stripe of glue or other adhesive, such as indicated at 17. The apeX 17 of the bottom flap 15 is adapted to terminate adjacent the ends 14 of the side flaps 13, substantially as illustrated in Figure 1 of the drawing.

The side flaps 13 are in addition provided with inwardly directed cut-out portions 18 having communication with upwardly, in-

wardly and obliquely dispos-ed cut-out portions 19, the purpose of which will be presently apparent. The cut-out portions 18 are adapted for registration whereby a continuous slot or pocket is formed of the configuration shown in Figure l.

By the aforementioned arrangement, the upper edge of a letter or other mailing matter within the envelope may be positioned within the upwardly, inwardly and obliquely disposed cut-out portions 19 and held against displacement by looking flaps 20 delined thereby whereby the address upon the latter or other mailing matter will be retained in registration with the window or sight opening 12.

From an inspection of Figures 1 and 2 of my drawing, it is noted that the sight opening or window is spaced from the upper edge of the envelope to conform with the United States Government postal regulations, regarding the distance of one and and threeeighths inches, whereby the particular envelope could be employed for self-addressed cards etc., where address is at or very near their top edge.

The locking flaps 2O may be so constructed as to agree with any desired posit-ion of address always keeping the outlook in the envelope at least one and three-eighths inches from the top thereof.

The invention will obviate delays in the postal service and communications sent in the improved type of envelope would never find their way into the dead letter office or department of the Postal Service for want of an address inasmuch as the same could be both exposed and protected.

The invention is lsusceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having thus described the invention, what is claimed is 1. An envelop-e having side, bottom and top flaps, a sight opening within the front thereof, and locking flaps carried upon the envelope side flaps to retain mailable matter against displacement therein.

2. An envelope having side, bottom and top aps and a sight opening in the front thereof, a transparent cover for said opening, the inner portions of the side flaps having outwardly extended cut-out portions coinmunioating With upwardly, outwardly and obliquely disposed out-out portions adapted to accommodate the uppermost edge of inailing matter Within the envelope to coincide the address thereon with said sight opening, and locking flaps formed by the cut-out portions being adapted to be bent over and upon the aforementioned edge of the mailing matter to prevent displacement of the latter.

In testimony whereof I aliix my signature.

SAMUEL C. JONES.
