ENVELOP-FASTENER.

SPECIFICATION forming part of Letters Patent No. 789,075, dated May 2, 1905.

Application filed June 25, 1904. Serial No. 214,193.

To @ZZ whom, it may concern,.-

Be it known that I, MAX TERLn'rzKY, a citi- Zen of the United States, residing at Goble, in the county of Columbia and State of Oregon, have invented new and useful Improvements in Envelop-Fasteners, of which the following is a specification.

This invention relates to envelop-fasteners, the object in view being to provide a simple, cheap, and reliable fastening device applicable to the ordinary flap envelop and comprising two members, one the complement of the other, by means of which the folding flap of the envelop may be securely fastened to the back or body portion of the envelop formed by the remaining liaps, thus preventing the envelop from being opened without injury thereto and partial destruction thereof.

The invention consists in the novel construction, combination, and arrangement hereinafter fully described', illustrated, and claimed.

In the accompanying drawings, Figure 1 is a plan view of an envelop equipped with the improved fastening device. Fig. 2 is an enlarged detail section through the envelop, showing the manner in which the two members of the fastening device engage and interlock with each other. Fig. 3 is a view of the inner member of the fastening device before being folded, which is secured to the back of the envelop. Fig. 4 is a view of the same device partly folded. Fig. is a view showing the device completely folded. Fig. 6 is a similar view of the opposite or outer side of the same part. Fig. 7 is a view of the outer member of the fastening device, which is secured to the folding iiap of the envelop.

Like reference-numerals designate corresponding parts in all iigures of the drawings.

Referring to the drawings, I have therein illustrated an ordinary envelop comprising the bottom Hap 1 and end flaps 2, which constitute the back or body portion of the envelop, and the scaling, closing, and folding iiap 3. Connected to the sealing-Hap 3 is one of the members of the fastening device, said member (shown at 4) being preferably in the shape of a disk, the central portion thereof being stamped out or cut away, as shown at 5, to leave an inclosed yielding tongue 6,

which extends the greater part of the way across the opening or cut-out portion 5 and is an integral part of the disk. The tongue 6, which has a slight bend backward from the face of the disk 4, as shown in Fig. 2, is provided adjacent to its free end with an aperture or lock-notch 7, the purpose of which will hereinafter appear. The other or complemental member 14 oi' the fastening device is shown in Fig. 3 and is made with a central body portion 8, attaching tabs or lingers 9, projecting in opposite directions therefrom and arranged in opposite parallel pairs, and a yielding tongue 11, depending from the body portion 8 between the tabs or fingers 9. Before securing the member 14 to an envelop it is folded as represented in Figs. 5 and 6. The tongue 11 is first folded on the line 12 close to the body 8, preferably at an acute angle thereto` as indicated in Figs. 2 and 4. The iiaps or fingers 9 are then folded over the tongue l1, their outer edges meeting' in the central line of the body, as shown, thus completing' the member, which is now ready for attachment to an envelop.

Referring to Fig. 6, which represents the outer or rear side of the member 14, the body portion 8 there shown is passed from within through a rectangular openingl formed in the meeting portions of the side flaps 2 and bote tom flap 1 of the envelop and thc folded tabs or lingers 9 pasted or otherwise secured to the inner face of the envelopback. (See Fig'. 2.)

The members 4 and 14 of the fastening device may be made of tough stiff paper, thin steel, brass, aluminium, or any material suitable for the purpose.

To seal the envelop, the fiap 3 is folded against the back of the envelop, and at the same time the tongue 6 is inserted between the body portion 8 and the folded tongue 11 until the locking-notch 7 reaches the extremity of the locking lip or catch 13, whereupon the catch snaps into the notch 7, thus causing' the interlocking of the tongues, which serves to fasten the sealing-flap down. After the envelop is sealed it cannot be opened without mutilating the fastening device in such a manner as to clearly show that the envelop has been tampered with. The flaps will be sup- IOO plied with mucilage and gummed together in the ordinary way, the fastening device hereinabove described being an additional safeguard.

Having thus fully described the invention, what is claimed as new is l. An envelop-fastener comprising two members, one having a body portion provided with a tongue bent over uponI the same and formed with a forwardly and laterally delected lip or catch, and portions folded over upon and inclosing said tongue and having terminal securing devices, and the other provided with a rearwardly-deflected tongue having a lock-notch to coact with the said laterally-deected lip or catch, said lip or catch adapted to pass through said notch into the Space between the body portion of the firstnamed member and its said rearwardly-dellected tongue, substantially as described.

2. An envelop fastener comprising two members, one having a rearwardly-deflected tongue provided with a lock-notch, and the other comprising a body portion having at one end a tongue adapted to 'be bent over upon the same and provided with a forwardlydeflected lip or catch, and side portions adapted to be bent over said body portion to inclose said tongue and formed at the ends of the body portion with lextended securing tabs or lingers, said forwardly projecting tongue adapted to pass through the notch in the rearwardly-deflected tongue into the space between said rearwardly-deflected tongue and the body of the member to which said latternamed tongue is attached, substantially as described.

3. The combination with an envelop provided with openings in its back and folding flap, of a fastener comprising an inner member secured to the inner face of the back and having an inclosed portion or casing exposed at said opening in the back of the envelop and provided with an outwardly-deflected tongue projecting into said casing and formed with a locking-lip, and an outer fastening member secured to the folding liap f the envelop and having an inwardly deflected or offset tongue projecting through the opening therein and into the casing in the inner fastening member and provided with a lock-notch to receive said lip, the latter extending through said notch into the space between the body member and its inwardly-deflected tongue, substantially as described.

4. An envelop fastener comprising two members, one consisting of a body portion slitted to form a tongue, said tongue being rearwardly deflected to form a receiving space or chamber upon the exterior thereof and having an opening therein, and the other member consisting of a body portion having a casing, securing tabs or fingers, and a tongue disposed in said casing, and having adeflected lip or catch to pass through the opening in the tongue of the first-named member, the secondnamedv member being formed from a substantially H-shaped blank havingafoldable tongue between two of its terminal arms, said tongue being folded over upon the body portion thereof, and the side portions and terminal arms of the blank folded over upon said tongue to respectively form a casing therefor and outwardly and oppositely projecting securing tabs or fingers, substantially as described.

In testimony whereof 1 afliX my signature in presence of two witnesses.
