Oct; 27, 1931. R. SATO FASTENER Filed Nov. 2, 1929 Patented Oct. 27, 1931 PATENT OFFICE RYUJI SATO, OF NEW, YORK, N. Y.

FASTENER Application filed November 2, 1.929. Serial No. 404,364.

This invention relates to improvements in means for binding loose leaves, and its leading object is to provide a simple, selfadjust able, binding strap, which can be extended through punched holes in the edges of a stack of paper or other sheets, and its ends interlooked to each other, so as to tie or bind the sheets into book form.

One of the objects of the invention is the provision of a flexible strap, preferably made of soft malleable brass or other metal, one end of which is formed with a series of transverse slots and the other end of which is formed with a tongue which may be interlockedin any one of the slots, so as to bind the paper sheets through which the device is extended.

Another object of the invention is to provide such a device with a coupling means, whereby the expansivo action of the paper sheets will force the ends of the binding device into interlooking engagement.

Other objects and advantages of the invention will be hereinafter specifioally pointed out, or will become apparent, as the specification proceeds;

With the above indioated objects in view, -the invention resides in certain novel construotions and oombinations and arrangement of parts, clearly described in the following speoification and fully illustrated in the accompanying drawings, which latter show embodiments of the invention as at present preferred.

In the drawings Fig. 1 is a view in perspective view showing a book of sheets held together by a pair of the binding devices.

Fig. 2 is a detail vertical sectional view taken on line 22 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is a detail sectional view taken on line 33 of Fig. 1. v

Fig. 4 is a perspective view showing the binding device in its original condition.

F ig. 5 is a detail perspective view showing difierent way of inserting the tongue.

Referring to the acoompanying drawings in detail A designates a flexible binding strip, preferably of soft, malleable metal, like brass,

copper, nickel-silver, or some other metal or allo of metals.

T16 body of this strip is folded upon itself to provide a binding band B, which is adapt ed to be inserted in the punohed holes H of a stack of sheets, indicated in Fig. l. On one end of the band B an arrow headed terminal or tongue C is formed, which is spaced longitudinally from the band by the neck Ca.

On the opposite end of the band the cou- 3 pling head D is formed, and this is spaced from the end of the band by means of the neck Da. This coupling head is formed with a series of diagonal slots E, which are spaced longitudinally from and are parallel to each other. This head D is wider than the folded band B, and the slots are each wide enough to receive the arrow shaped looking tongue C.

The band is connected to the sheets to be bound, by extending the arrow shaped head through the punohed holes of the sheets, and folding the band upon itself, so that the locking head D will enter one of the slots E. The looking head is forced through the slot selected for coupling, in the manner shown in F igs. 1 and 2, by forcing the tongue through the coupling head from the outside thereof, so that the tongue will be disposed between cou pling head and the opposed edges of the book of sheets.

If a number of sheets are added to the book of sheets, the tongue may be located in another slot, and if a number of sheets are eX- tracted from the book the position of the looking tongue may be changed acoordingly.

Owing to the diagonal disposition of the slots of the ooupling head, the looking tongue when inserted in one of these slots will slide laterally, so that end of the slot will enter the neck Da of the looking tongue, thereby preventing endwise withdrawal of the looking tongue from the ooupling head.

The f0lded edges of the band form a smooth surface on each side of the band, and thus prevent the band from cutting the paper or other material clamped.

A p ack of sheets bound together by a pair of the binding devices will open and close like a flat opening book.

The looking tongue is formed with a relatively sharp point, which niay be forced through paper so thatthe binding device will make its own holes in the paper. When the device is used in this way the coupling head may be disposed against one side of the bound sheets, instead of against the edge faces thereof, as shown in Fig. 1. y

The hereiribefore described construction admits of considerable modification without departing from the invention; therefore, I

do not wish to be limited to theprecise ar- 7 rangements shown and described, which are, A

as aforesaid, by way of illustration merely.

In other words, the scope of protection con templated is to be taken solely from the appended' claim, interpreted as is consistent with the prior I claim asnew: r g

ZA binding device consisting of a band of flexible material formed with a coupling head on one end thereof, and provided with a series art.

of slotsspaoedfrom each other, each of the 7 slots being disposed diagonally in, the head,

the other end of the band beingfornied with a looking tongue of arrow shape insertable ineither one of the slots and a-dapted to slide against the end of the slot under the tension of paper sheets around which the band is placed, the band being fold'ed upon itself to provide rounded side edges.
