Application filed May 18,

T 0 all whom it may concern:

Be it known that I, EUGENE F. Nissan, a citizen of the United States, residing at Alameda, in the county of Alameda and State of California. have invented a new and useful Improvement in Envelope Fas' teners, of which the following is a specification.

This application relates to a fastener, particularly adapted to be used upon envelopes and like containers.

It is the principal object of the present invention to provide a metallic fastener which may be firmly secured to a sheet of material such as the body panel of ,an envelope in a manner to prevent the ready removal of the fastener by unauthorized persons, said fastener carrying tongues adapted to extend through the eyelet of an envelope flap and to be thereafter separated to hold the flap in position and to permit a wax seal to be easily applied in a manner to completely conceal the tongues and the fastening? element.

The present invention contemplates the use of a fastener being pressed from a single piece of thin sheet metal to form a diskshaped body having a plurality of pointed tangs arranged around its periphery to be bent outwardly after having passed through a sheet of material and other tangs in the body of the disk adapted to be bent inwardly, said disk being further formed with a pair of tongues which may be passed through an envelope eyelet.

The invention is illustrated by Way of example in the accompanying drawings, in which:

Figure 1 is a view in perspective illustrating the fastener in position to be applied to an, envelope.

Fig. 2 is a view in perspective illustrating the positions of the various tangs after the fastener has been applied to them.

Fig. 3 is a view in elevation showing the fragmentary portion of an envelope with the fastener applied thereto, and drawn on an enlarged scale.

In the drawings, 10 indicates a body plate preferably formed from thin gauge metal to provide a circular disk of small dimensions. Formed integral with the plate and extending radially from the circumference thereof is a plurality of tangs 11. These tangs are pointed and when bent downwardly as indicated in Fig. 1 may be readily 1920. Serial No. 332,431.

passed througha sheetof material to which the fastener is secured. WVhen-the fastener is blanked out, it is preferable that eight marginal tangs shall be formed. However, after the operation is completed two of these tangs extend from the ends of fastening' tongues 12. These tongues extend from points near the center of the plate 10 and may be bent up as shown in Fig. 2 so that they may be passed through an opening or eyelet 13 formed upon an envelope flap. A pair of tangs 14 are also struck from the disk 10 and through the body thereof. In providing the two sets of tangs 11 and 14, it is intended that they shall be both passed through the same sheet of material and that the tangs 11 shall be bent outwardly to assume positions in radial alignment with the disk 10, while the tangs 14 are bent inwardly to extend radially and toward the center of the disk. arrangement it will be practically impossible for persons to remove or replace the fastener in an effort to reach the contents of the envelope without detection. After the fastener has thus been secured to a sheet of material the tongues 12 may be bent upwardly as shown in Fig. 2 so that they may be used to secure an envelope flap in position as shown in Fig. 3.

The flap may thereafter be sealed by completely covering the area represented by the fastener and thereby insuring that the fastener shall never be molested without detection. It will thus be seen that the fastener here disclosed, while simple in construction and readily manufactured may be so applied to an envelope or other sheet of material as to be firmly held in position without possibility of removal without having some sign by which the tampering would be detected.

While I have shown the preferred form of my invention as now known to me, it will be understood that various changes in the construction, combination and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as claimed.

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

1. An envelope fastener including a disk having radial outwardly projecting peripheral points, foldable outwardly, other points formed within the periphery and Due to this foldable inwardly; and aligned strips cut from the body of the disk having points extending outwardly beyond the peripheral edges of the disk, and foldable thereon.

2. An envelope fastener comprising a disk having spaced points projecting from its periphery and foldable outwardly, other points out within the body of the disk and foldable towards the center from their points of attachment; and stripsseparated from the body,extending in opposite directi0ns, with points beyond the edges of the disk, and foldable to secure an envelope flap. r p

v 3. An envelope fastener comprising a body plate'havinga plurality of fastening W. W; HEALEY, WV. E. EWING.
