shows in perspective a package held together by my improved binding-strap. Fig. 2 is a sectional view, on an enlarged scale, showing how the ends of the strap are fastened together. Fig. 3 is a perspective view of the strap alone. f A

A is the strap, made, preferably, of metal, as brass or steel, and sufficiently thin to be flexible in the direction of its length, but quite sti transversely. One end A of the strap is perforated with a series of holes a', extending back into the body thereof, while the other end A2 terminates in a tongue a,the width of which is slightly less thanthe diameter of the holesu. The end Azalsohas the hookV a2 preferably struck down from'the material of the strap, as shown, and `in such a position thereon that when the tongue d is pushedinto.Y

one of the holes d as far as it will go the hook CL2 will just engage with another of saidholes a in such a manner astolock the strap firmly vtogether. lhen arranged as in t-he drawings,Y the hook a2 engages with the third hole from the one into which the tongue d is inserted. By having the strap perforated for a considerable distance along the end A2 it will be seen that a strap of a single size'may be used for bundles or packages of various sizes, according to the hole into which the tongue a is inserted. either tightly or loosely, as desired, thus being perfectly adjustable, it being a very smple operation to change the tongue d and hook a2 from one to another of the holes c. The construction is such that the strap is doubly locked, soas to be incapable of being accidentally unclasped. Both the tongue a and the hook a2 acting together are essential to this end. lere the tongue'a, omitted, so that the clasping together of the strap depended alone upon the engaging of the hook a2 with one of the holes, the said strap would continually be liable to accidental unclaspin g by reason of the fact that a loose projecting end would be left beyond the hook d2 to be easily caught when the bundles are being moved about, besides being liable to tear papers, &c., in contact therewith. Vith the tongue d, however, interlaced into the strap previous to hooking there is no loose end to catch and tear papers and absolutelyno danger of accidental unclaspin g.

I claim- YA bindingystrap one end of which is provided with a series of holes, while the otheris provided with a tongue adapted to enter one of said holes, and a hook back of said tongue other of said holes,whereby the strap is doubly clasped', substantially as described.

In witness whereof I have hereunto set my hand.

Moreover, the strap may be clasped.
