QFFICE ENVEL OP-FASTENER.

SPECIFICATION forming part of Letters Patent N 0. 657,439, dated September 4, 1900.

' Application filed May 9, 1900. Serial No. 16,090. No model) To all whom it may concern:

Be it known that I, JOHN OTTO MUENICH, a citizen of the United States, residing at Jefferson, in the county of Jefierson and State of Wisconsin, have in vented a new and useful Office'Envelop-Fastener, of which the following is a specification.

This invention relates to fastening devices for envelops, files, and the like which are commonly tied with a cord or tape, and has for one object to provide an improved fastening for permanently securing one end of the cord or tape to the file or similar package and also constructed to secure the opposite free end of the cord after the latter has been wrapped about the envelopor file.

A further object of the invention is to facili: tate the engagement and disengagement of the free end of the cord from thefastening and also to provide for a positive and secure engagement of the free end of the cord with the device.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be herein after more fully described, shown in the accompanyin g drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion,

size, and minor details may be made Within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a plan view of 1 designates the body of a file-wrapper or en-- velop having the free edge or flap 2 to'over-.

lap the adjacent edge of the body in any common or preferred manner, and 3 designates a cord or tape which is commonly -wrapped around the envelop, and the opposite ends of the cord are tied together, so as or fingers 5, which are duplicates: in form.

These parts are preferably struck from a single blank of metal, so as to be integral, each armor finger being bowedupwardly at an intermediate point and having its outer extremityflaredupwardly, so as to form a lip 6.

To connect the fastening to the flap portion 2 of the envelop,'said flap is provided with a perforation 7," as indicated in Fig. 2, and the head is placed so that the perforation thereof may correspond to the perforation in the flap, and then an eyelet or rivet 8 is passed through the alined perforations, after which the inner end of the-eyelet or rivet is upset againt the inner side of the flap, so as to secure the fastening thereto. Before upsetting the rivet or eyelet the inner end thereof may be provided with a ring or washer 9, so as to prevent the fastening from being torn from the envelop. Prior to the insertion of the rivet or eyelet one end 'of the cord or tape is placed beneath the opening in the head, so that the rivet or eyelet carries the cord or tape through the opening in the flap, and when upset the cord or tape is fixedly held to the fastening and also to the envelop. When secured in place, the outer end portions of the spring arms or fingers rest against the adjaoent face of the envelop and the lips 6 flare outwardly and away from the envelop.

To fasten the envelop, it is closed or folded in theusual manner and the free portion of the cord or tape is wound about the envelop, '-after which the free extremity of the cord is engaged beneath both spring-fingers and laterally across the head, whereby said cord is wedged beneath the spring-fingers and across the head of the fastening. It will now be ap- [parent thatthe lips at the outer extremities of the spring-fingers facilitate the passage of the cord beneath the fingers. 'To-disconnect the cord, it is merely necessary to draw the free end thereof from beneath the spring-fingers, when the cord is free to be unwrapped from the file or envelop.

To provide a more positive engagementof the cord with the fastening device and to preclude the possibility of the former slipping upon the "latter, the head is provided with one or more spurs or prongs 10, preferably a pair thereof, as shown in Fig. 5, which are a designed to pierce the cordor tape in the manner shown in Fig. 3, and thus prevent slipping of the free end of the cord. The' spurs or prongs are located upon that side ef '1 the head from which the fixed portion ef the a cord or tape extends, so that the latter is beneath the pnen gs, and therefore does not 'interfere' with the engagement of the free end s of the cord as the latter passes transversely across theonteraside of the @fixed end thereof. 1: It will of course be understood that instead of placing the fastening upon "the flap of iihe i turizng spurs orprongs for engagement a flexible tie. 2. The combination with a receptacle, ofa f flexible tie, and a fastening or tie-engaging device havingnieans extending through reg" istering openings in, and engaging, said tie and the receptacle, the fastening being vprovided with one or more spring tie-engaging arms.

3. The combination with an envelop, file- 'wrapper'orthe like, of a fastening secured thereto, and having one or more prongs or spurs, and a cordtor the like, having one end fixedlysecured to the fastening, audits op posite free end being arranged for engagement with the spare er prongs.

4. A fastening of the class described, cornprisinga head, having an attaching-shank, an outwardly-directed spring arm or finger, one or more lateral spurs or prongs, and a cord having one end fixedly secured to the fastening and "its opposite free end being arranged fer engagement beneath the fingerand also with the prongs nor spurs.

5. A fastening-of the elass described, comprising a head struck from single blank-of metal, and provided with a central pertoration, opposite spring-arms, and one "or more spurs or prongs arranged between the fingers,

and an attach-ingriveit-oreyelet received withi in the perforation.

In testimony that claim the foregoing-as my-own I h'ave heretoaffixed my signature in the presence oftwo witnesses.

JOHN OTTO MUENIOH.
