PAPER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 693,302, dated February 1 1, 1902.

Application tiled August 2l, 190.1. Serial No. 72,757. (No modelnew and improved paper-fastener which is simple and durable in construction, easily applied to fasten a desired number of superimposed sheets securely together, and to provide an eyelet for the passage of a seal-ribbon for sealing the papers.A

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,l

forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure lis a rear face view of superimposed sheets with the front member of the fastener shown in dotted lines in position. Fig. 2 is a rear face view of the sheets with both members of the fastener in position. Fig. Sis a like view of the same with the partsin a different position. Fig. 4 is a like view of the same with the members of the fastener securely locked together. Fig. 5 is an enlarged sectional elevation of the improvement on the line 5 5 of Fig. 2, and Fig. 6 is a perspective view of the front member.

The improved paper-fastener consists, es-

sentially, of the members A and B, made of sheet metal or other suitable material, and between which the' superimposed sheetsO are held and fastened together, as hereinafter more fully explained. The member A is preferably used on the front face of the superimposed sheets, and is hence the front member, while the other member is applied to the back of the superimposed sheets. The front member A is provided at diagonal corners with pins D, adapted to pass through the superimposed sheets Gand through registering apertures E, formed in the rear member B, as

plainly indicated in Fig. 5. The pins D are bent onto the outer face of the back member B, the bent-over portions of the pins extending longitudinally parallel to each other, as plainly indicated in` Fig. 3, and in order to conceal the pins and to lock the samein place aps B', extending integrally from the rear memberB, are bent over onto thesaid pins, as plainly indicated in Fig. 4. The front member A is provided at or near its middle with an aperture A', registering with asimilar aperture B2, formed in the rear member B,"and the side edges of the flaps B' are formed with cut-out portions B4, so that when the flaps are folded over the pins, as previously explained, then the said iiaps do not cover up the aperture B2, as the cut-out portions B4 registerv with the aperture. Thus a seal-ribbon may be readily passed through the fastener whenever it is desired to seal the papers, it being understood that the paper material of the sheets E extending in the apertures can either be punched out previous to applying the fastener or it may be readily cut out by a knife or other suitable tool after the fastener is applied. In order to prevent the pins D from being accidentally bent over the apertures B2, I prefer to form on the outer face of the rear member B an annular boss or projection B3, surrounding the aperture B2 and forming a guard for the pins D. The boss B3 is otabout the same height as the thickness of the pins D, so that when the flaps B are folded upon the pins the boss does not project beyond the outer faces of the flaps.

In using the device the front member A is pressed against the superimposed sheets C, so asto cause the pins D to penetrate the sheets, and then the rear member B is engaged with the pins on the back ofthe sheets, after which the pins are bent over, as described. Then the iiaps B are folded upon thel pins to conceal andlock the same. The papersare now securely clamped between the members A and B. v

The device is very simple and durable in construction, can be very cheaply manufactured and readily applied, and whenever it is desired to disconnect the superimposed sheets the user can readily bond thctlaps B back to their original position and then bend the pins back and separate the members A and B from each other.

As the pins D are completely concealed, it is evident that they cannot catch on other papers or other articles with which they come in contact. g

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A paper-fastener comprising two members, of which one is provided with pins for passing lthrough the papers and for engaging the other member, the said members having registering apertures for the passage of a sealribbon, and fiaps on the other member for concealing and locking the pins without covering the registering apertures, as set forth.

2. A paperfastener, comprising a front member having a plurality of pins, a rear member having apertures for the passage of the pins, and iaps extendingintegrally from the said rear member for folding over the pins to conceal and lock the pins in place, the rear member having a boss for guiding the pins into a bent position, as set forth.

3. A fastener comprising a member provided with pins and with a ribbon-receiving aperture, and another member provided with perforations arranged similarly to the pins on the first-named member and also provided with a ribbon-receivin g opening, whereby the members may beassembled 'for the pins to pass through the perforated member and the ribbon openings of the two members are brought into registering relation.

4. A fastener comprising two members each having a ribbon-aperture, and means for positively locking or uniting said members together, whereby the apertures in said members may be brought into registration and adapted to receive a fastening-ribbon.

5. A fastener comprising a member having pins and a ribbon-opening, another member provided with apertures and with a ribbonopening, and bendable aps projecting from the last-named member and having notches arranged, in the bent positions of the aps, to lie coincident with the ribbon-opening in the member.

6. A fastener comprising a member having pins projecting from diagonal corners thereof, and also having a ribbon-aperture, another member provided with pin-apertures and with a ribbon aperture, and flaps on the lastnamed member adapted to be individually bent into locking engagement with the ends of said pins when the latter are bent onto tho last-named member.

In testimony whereof I have signed my name to this specification in the presence of two witnesses. v 4
