THT-f- UNITED STATES PATENT OFFICE.
CHARLES A. DUNN, OF WEST HOMESTEAD, PENNSYLVANIA.
ENVELO P.
SPECIFICATION fom ing part of Letters Patent No. 707,308, dated August 19, 1902.
Application filed March 21, 1902. Serial No. 99,265. (No model.)
To all whom it may concern:
Beit known that LCHARLES A. DUNN, a citizen of the United States of America, residing at 'Vest Homestead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Envelops, of which the following is a specification, reference being had therein to the accompanying drawings. Y,
This invention relates to certain new and useful improvements in envelops, and relates more particularly to that class that cannot be opened without detection. Y.
The invention has for its object the provision of novel means whereby anyY tampering with the envelop may be easily discerned; furthermore, to construct the locking edges in a manner that will securely seal the envelop and retain the contents in proper position therein. u
The invention further aims to provide an envelop of the above-described character that will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.
With the above and other objects in view the invention consists in the novel c0nstruc,
tion, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.
In describing-the invention in detail refer` ence is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views,in which- Figure 1 is a plan view of myimproved envelop-blank. Fig. 2 is a similar view showing the securing-flap placed in position and the upper tongue applied to the securing-flap. Fig. 3 is a plan View of the envelop when sealed. Fig. 4 is an enlarged detail view of the elongated strip for securing the end and sides of the envelop.
In the drawings, l represents the front, and 2 the back, of the envelop, said back 2 having a cut-away portion Sin its free edge, and the front l is provided with two vertical slits eX- tending but a short distance into th`e`body of the front, thus forming a tongue 4 of sub-` stantially the same length as the cut-away portion 3 in the back 2. This tongue is gummed, and when the back and front are brought together or folded the tongue 4 is adapted to be folded over Aand engagey theback, `as shown in Fig. 2. This fold isof course not made until after the letter has been/placed in the envelop. The front l is of slightly greater length than the back 2 and is provided with crease-lines, so that the extended portions 5 may be bent over and form securing-naps, they being gummed to adhere to the back 2. The blank is formed with securing-strips of unequal length at its ends. These strips are madeintegral withthe blank centrally of its ends,.the stripY 6 at one end having an exthe edges of the front and back after the latter have been folded and the letter placed in the envelop. The strip 9 at the opposite end of the blank is adapted to fold against the end of the envelop. These strips 6 and 9 and the extension.7 of thestrip 6 are provided with a crease 10, extending throughout the length of the strips and also forming the crease-line or fold-line between the front and back. When, therefore, the securing-strips are folded and doubled on their crease-line, they embrace both the backand front at the ends of the envelop, while the extension 7 embraces the upper edge of the envelop.
vThe strips and extension are gummed to adhere to the back and front when folded into position. In order to permit the easy folding of the stripsand 9 into upright position and the folding over of the extension 7 onto fthe edge of the envelop, I provide the strips the latter has been placed 'inlthe'envelop the tongue 4 is folded over andfengaged. with tension 7, which is adapted to be folded upon l the back, the strips 6 and 9 folded against v the ends and adhered to both front andback,
and the extension 7 folded on the edge of the Ion( envelop and adhered to front and back, when f y the back, yet it will be observed that both sides of the envelop are the same when the seal is completed, so that either side thereof may be used as the front or address side.
It will be noted that various changes may be made in the details of construction Without departing from the general spirit of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. An envelop-blank consisting of a front and back, the front being of greater length than the back to form wings adapted to fold on said back, and securing-strips formed integral with the front and back and adapted to be doubled so as to engage both the front and back, substantially as described.
2. An envelop comprising a blank having a front forming one side of the envelop and a back forming the other side of said envelop, the front being of greater length than the back and adapted to have its extensions folded over to engage the back, a tongue carried by the front adapted to engage with the back,
and end-securing strips carried by the blank, one of said strips adapted to engage the one end of the envelop, and the other strip adapted to engage the opposite end and the edge of the envelop, substantially as described.
3. In an envelop, the combination of an upper and a lower securing-flap, one of said flaps carrying a seouringtongue and the other of said flaps having a eut-away portion adapted to receive said securing-tongue, securing ends carried by said flaps intermediate their ends, said securing ends adapted to be creased and bent upwardly to inolose the sides of the upper and lower securing-flap, one of said securing ends adapted to be bent over the upper sides of the said upper and lower securing-fiaps and adapted to inolose said seouring-tongue, substantially as described.
In testimony whereof I affix my signature in the presence of two Witnesses.
