To all whom itmay concem:

Be it known that I, JAMES W. GRANT, a citizen of the United States, and a resident of Bridgeport, in the county of F airfield and State of Connecticut, have invented certain new and useful Improvements in Paper-Fasteners, of which the following is a specification.

This invention relates to fasteners for filing papers, such' as letters, documents and the like, and more especially to that type of fastener which consists of a base portion and two tongues adapted to be pushed through the papers to be filed and I then bent down flat against the papers.

The main object of the invention is to provide a paper fastener of this class, which shall be adapted for forming files of greatly varying thickness by the use of but a few sizes of fasteners or fastener parts. An

other object is to provide a fastener especially adapted to be manufactured in large my improved paper fasteners.

Fig. 2 is a longitudinal section showing such a fastener applied to a file of pa ers.

Fig; 3 isa plan of the bottom'of' t e fastener with one tongue removed.

Fig. 4 isa transverse section of my improved fastener on a line through the transverse bar on the base.

Fig. 5 is a detail of one of the tongue members. 1

Fig. 6 is a perspective view of a modified form of mv invention.

Fig. 7 is a perspective vlew of another modification.

Like characters refer to like parts in all .1 figures of the drawlngz.

My improved paper fastener illustrated in the drawing consists of a rectangular base member 1 of sheet metal, and two de-" tachable tongue members 2, which are some- What narrower than the base, and preferably of a more pliable grade of sheet metal than the base member.

The base member 1 hastwo longitudinal parallel ridges 3, forming a groove 4 be-.

tween them of substantially the same width as the tongue members, the said ridges and groove, together with the other portions of the base member being preferably made of a single piece of sheet metal, and having all of the parts integral. Neareach-end of'the base is provided a band or, bar'such as 5,

which forms a connection between the ridges. On each side of the band or bar f are openings or slots such as 6 in the base member for a scribed. 4 Y

The tongue members 2 are provided near each end with stamped lugs 7 "preferably rounded, each ofwhich is connected to the body of its respective tongue member by portions 8. The outlines of the lugs 7 are stamped clear through the metal except at the portionsf8, but said lugs 7'rema1n flat in the tongue member without being bent purpose hereinafter to be dey out of the plane of the same, until said tongue member isinserted in the base member. Their tips 9 are spaced apart a distance e ual to the width of a band or bar 5.v

The asteners'are assembled by inserting a tongue "2 in the groove 4 near the end of the base 1,and passing it between the band or bar 5 and the. flat surface 10 of the base until the tips 9 of thelugs 8 are in line with the edges of the band or bar 5 at that end.

I The lugs- 7 are both pressed down by in sorting a suitable implement through the- I openings or slots 7, causing the lugs to project and engage the band or bar 5, locking the tongue to the base. The second tongue is secured to the other end of the base, and the free ends of the tongues are swung around, bending them over the ends of the, base, and bringing them at right angles thereto. The fastener can then be used for filing by passing the tongues 2through the I papers as far as they will go, and then bending the ends flatjon the topmost paper,

or 'on top of a washer if one is used. This is illustrated in, Fig. 2, where the apers are indicated by the numeral 11 and t e washer b '12. By emplo in' tongues of different l ngth's files of i ari u's" thickness can be formed, corresponding to the lengths of the tongues employed. g

In the form of my invention illustrated in Fig. 6, the base member is the same in all respects as the base described the foregoing, but the tongue members 2 are each provided with only one lug 7 which is formed to engage with the inner 'ed es only, of the transverse bands or bars ,5.

he said I tongue members are assembled as described tongue at 15 around into the roove 4, then bend it around theend of the ase 1, alining the-portion 16 by the groove 4. I

- O the paper fasteners now in use,'there is one sort that consists of a rectangular y base, and a long tongue member passed through two. slots in the base' near the ends and which is then bent around each end at right angles, forming a tongue at each end of the base. Another form consists of a rectangular basewith a .tongue at each end,

integral with the base. In ,my present invention I have improved over both these forms by effecting an econom of material, and in other ways. Compare with the first mentioned; form I' am able to produce a given number of fasteners with less tongue material.v Compared with the second, I. am

.,able to produce a given number of fasteners with less. scrap in the stamping operations. Again in comparison with the'second form,

as many sizes of fasteners as are required.

My improved fasteners are packed'for sale 1n boxes .without assembling the tongue. members on the bases, so that I am able to pack a maximum number of. parts in a box or packa with the gsteners now on the market.

I claim; v
