FASTENER Filed Dec. 19, 1932 Patented Sept. 17, 1935 UNITED STATES PATENT OFFICE FASTENEB,

Daniel A. Brennan, Chicago, Ill.

Application December 19, 1932, Serial No. 647,909 In Canada March 19, 1929 31 Claims.

The invention relates broadly to fasteners, and more particularly to fasteners for binding loose papers together in a file, comprising a base having tongues or prongs at its ends adapted to extend over and be held bent down against a keeper or compressor.

An object of the invention is to provide an improved fastener of the character referred to with a novel keeper for holding the tongues in binding engagement therewith against the papers in a file.

Another object is to provide a paper fastener with a novel keeper, having improved means cooperating with one tongue, arranged to draw or clamp the papers together prior to bringing the other tongue into its final co-operative position.

Another object is to reduce the number of moving parts, in a paper fastener of the sliding lock type, and thereby reduce the cost of manufacture, simplify its mode of operation, and provide a more efficient product.

The foregoing and such other objects of the invention as will appear hereinafter as the description proceeds will be more readily,understood from a perusal of the following specification,

reference being had to the accompanying drawing, in which:

Fig. 1 is a perspective view of a fastener embodying features of the invention.

Fig. 2 is a longitudinal sectional view of the fastener of Fig. 1, showing the lock positioned over the bent down tongue.

Fig. 3 is a longitudinal sectional view of a modified form of keeper, shown attached at one end to a tongue.

Fig. 4 is a plan view of the keeper shown in Fig. 3.

Fig. 5 is a transverse sectional view of the keeper taken on line 5-5 of Fig. 3.

Fig. 6 is a plan view of a modified form of keeper.

Referring particularly to Figs. 1 and 2 of the drawing, the fastener constituting the preferred embodiment of the invention, comprises a base 10, provided at its ends with spaced tongues H,

adapted to pass through similarly spaced apertures I2 in the file of papers l3. Preferably, the tongues II are substantially less in width than the body of said base and are struck up substantially at right angles thereto, as shown.

The base I0 normally is positioned to lie flush against the bottom of the file papers l3, and a keeper H is adapted to be placed in co-operative position with the base against the top of the file papers. When in this position, the keeper and the projecting ends of the tongues are in position to co-operate to bind the papers securely.

The keeper I 4 preferably consists of an elongated strip of stiff material formed with an upset or shoulder l5 at one end and an elevated transverse strap l6 adjacent said upset. A transverseaperture ll preferably is provided adjacent the other end of the keeper between parallel tracks l8 which extend longitudinally inwardly and outwardly from said aperture. 10

The tracks l8 preferably are struck up from the keeper in the form of ribs and have their ends I9 curved outwardly toward the longitudinal edges of the keeper to provide stops for a lock 2i mounted thereon for movement inwardly and 15 outwardly over the aperture l1. As shown, the lock or latch 2| preferably consists of a strip of material having its ends bent under the marginal flanges 22 which are elevated from the plane of the bottom of the keeper to allow free sliding of 20 the lock without its ends catching in or tearing the papers.

In operation, the keeper is placed with the strap 16 over one of the tongues said tongue being at right angles to the file papers and then swung 25 downwardly against the file ofpapers at which time the other tongue passes through the aperture l'l. With the keeper now fiat against the papers, the projecting end of the tongue extending through aperture H is bent down over the Q keeper, between tracks l8 and the lock 2| is moved over the bent down tongue to retain it in place. It will be noted that said tongue may be bent down inwardly or outwardly of the aperture 11 and locked, the lock 2| being slidable 35 inwardly or outwardly of said aperture. It is preferable that a suitable projection Ila be provided adjacent the end of the tongue that extends through aperture ll to limit inward movement of the lock 2| from coming off the end of the 40 tongue when the bent over portion of the tongue is shorter than the inwardly extending portions of tracks l8, due to the binding of a relatively thick file of papers. If desired, a short tapered rib l lb for frictionally co-acting with the lock to 45 prevent accidental misplacement thereof while in binding position, may be provided.

The keeper is held tightly against the papers at the other end by reason of the upset or shoulder end I5 which serves as a cam in co-operation with 50 the tongue engaged thereby to draw the keeper and base together, against the papers.

In the form of fastener shown in Figs. 3, 4 and 5, the keeper is provided with longitudinal guides 23 formed by folding the marginal edges 55 of the keeper upwardly and inwardly. A slot lib is provided at one end to receive one of the tongues ii and the guides 23 are depressed as at 24 and 25, to limit movement of the lock 20, guided therein, to one end of the keeper. Said lock preferably is folded over the top of the guides, as at 26a, to hold it elevated. It is preferable that the tongues ll be provided adjacent their ends with tapered ribs lib to insure retention of the lock over the tongue. The guides at the other end of the keeper are of greater width to provide a longitudinal receptacle or sheath open at its end to receive the other tongue, as shown.

Fig. 6 shows a keeper having a receptacle at one end formed by upwardly struck opposed longitudinal parallel lips 21, to receive one of the tongues II, and an aperture llc adjacent the other end. The end of the other tongue passes through the aperture lie and is bent down inwardly against the keeper and sprung laterally to engage beneath a lip 28 on the keeper.

It can be readily understood that the fasteners shown in various embodiments in the accompanying drawing and described in detail in the foregoing specification, effect a tight clamping of the papers in the file and although exemplary embodiments are shown and described it is to be understood that the invention is to be in no way limited to the precise structures shown but is to embrace such structures as fall within the spirit of the invention and the scope of the appended claims.
