To all whom "it may concern:

. Be it known that I, Emswon'rn E. FLORA, a citizen of the United States, residing at Chicago, in thecounty of Cock and State of Illinois, have invented a new and useful Improvement in Fasteners for Metal Straps, of which the following is a specification,-

My object is to provide, a particularly simple, secure and easily applied fastener for the meeting ends of metal strips or straps, such as are employed upon boxes, bales and the like packages.

In. the accompanying drawing-Figure 1 is a perspective view of a metal-bound box of the Simplex type to which is applied a box-strap secured at its ends by my improved fastening means; Fig. 2, an enlarged broken perspective view of the fastenerparts before they have been secured together; Fig. 3, a similar view showing the ends of the strap'bent over the endsofa.

retaining sleeve to holdthe parts-against relative slipping; and Fig. 4, a similarview showing the way the arts are secured to fasten them permanent y together. e

The box illustrated is of a welle own metal-bound type consisting of top, bottom, side and end-sheets held tegether by'ithe binding-strips 6. On the'en s of the bind;

in -strips are tongues 7 projecting est the edge of the cover and adapted to be" astened down with seals applied at the perforations 8 in a we -known manner. 1 Extendin around the b x between its ends is ameta strap 9 which' maybe fastened to the sheets with staples 10. The-purposeof-the strap is to give additional security to thebox and prevent separation by warping of the meetmg edges of the sheets- The numeral 11 desi nates'a rigid metal-v sleeve or channel-piece aving gaps 12 midway of its ends at-"opposite sides. The bore of'the sleeve is just large enough to permitthe opposite ends of the strap to be passed through it from oppositedlrections and overlie one another. -When the strap-ends" are passed through the sleeve, the marginal portions of the straps are exposed in the forth.

and squeezed against the marginal portions of the straps to crimp or bend them out of their original alinement, as shown at 13.

v.The shoulders thus presented by the straps to each other and to the marginal edges of the gaps hold the parts securely together.

The sleeve 11 may only partly encircle-the strap-ends instead of completely encircling them, as shown, and the gaps 12 in the sleeve may be of rounded or any otherform instead of angular, as they are illustrated. In applying the fastener one'strap-end may be passed through the sleeve and bent-over upon the same, so that whenthe other stra end is passed through the sleeve it may drawn taut without danger of the other ends slipping out of, the sleeve, as illustrated in Fig. 3. When both-strap-ends are bent over the sleeve they hold the parts against While'I prefer to provide my improved fastening means as shown and described, the construction may bevari'ously modified in the matter of details without departin from '70 relative'slipping while a tool is being ap-- plled to form the crimps 13.

the spirit of my invention as defined y the claim.

'What I claim as new and desire to secure by Letters Patent is- In a device of the character described, ametal strip, a sleeve embracing said .strip lengthwise thereof and through which the strip-ends are passed to overlie one another, the said sleeve .being provided with openings in its sides to expose the strip ends on .the top and bottom of the sleeve, said ends being compressed toward the center of said strips, whereby the same are caused to resent shoulders to each other and to the e ges. of the sleeve openings, for the purpose set ELLSWORTH E. FLORA. In presence ofv L. Hmsuin, R. Somme.
