BOX-STRAP.

SPECIFICATION forming part of Letters Patent No. 403,178, dated. May 14, 1889.

Application filed March 5, 1888. Renewed October 13, 1888. Serial No. 288,048. (No model.)

To all whom it may concern: 1

Be it known that I, SPENCER O. CARY, of Baldwin, county of Queens, State of New York,a citizen of the United States, have in- 5 vented an Improved Box-Strap, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a metal box-strap;

and it consists in a box-strap composed of a metal band having a series of successive bosses at each side edge and extending longitudinally thereof, substantially as hereinafter particularly set forth, and for the purposes hereinafter specified.

Figure 1 is a plan of a box-strap containing my invention. Fig. 2 is a vertical longitudinal section of the same on line m ac, Fig. 1. Fig. 3 shows my improved box-strap bent or turned flatwise over the corner of a box or packing-case. Fig. 4 is a plan showing the lapped ends of two lengths or sections of my improved box-strap and the joint which I employ to unite the same to constitute a contin- 2 5 uous band; and Fig. 5 is a vertical cross-section on the line y y, Fig. 4.

A represents a metal band of indefinite length.

At B B are shown series of successive bosses 0 formed upon one and the same face of the band A and projecting above said face at each side edge, respectively, of the band,and extending throughout the length thereof. These bosses may be circular in outline, as shown, or may 3 5 be given any other outline desired. Theyare arranged in series, as stated, along each of the respective side edges of the band, and between the adjacent members of each series is a web of the metal of the band, as shown at b b in the respective series. This intervening web or face of the hand between the members of each series may be greater or less in extent, as may be desired, without material variation from the essential feature of my invention.

In carrying out my invention I find it pref= erable to have the bosses in each series set or formed in near proximity to each other, as shown in the drawings, with the space or web of metal between them of somewhat less extent than the diameter or length of the bosses themselves, as shown. I also find it prefer:- alole to have the bosses of uniform shape or outline and size or extent, and to have them arranged equidistant from each other throughout the series, as shown, and with each individual boss in the series at one edge of the band located opposite to an individual boss in the series at the other edge, as shown. when thus constructed, the ends of two lengths or sections of the strap may be overlapped, and the crowns or projecting surfaces of the series of bosses on the under section will fit into the recesses constituted by the bosses in the upper section, on the under face thereof, thereby enabling the lapped ends to constitute an even fiatwise joint upon each other. When the ends are thus overlapped, I am enabled to form a permanent joint between the sections of band by punching a hole, 0, through the central portion or web of one of the sections of band at or near the end thereof, and cutting through the web portion of the other band in radial slits, so as to form therein the lugs or ears 0', adapted to be turned around and over the rim of the hole 0 and down upon the exposed face of the section in which said hole is formed, as stated. In place of doing this the equivalent thereof may be donenamely, punching corresponding holes in the lapped section ends and securing the ends together by an eyelet passed through said holes and clinched down upon the webs of the bands.

The advantages of a joint between two sections or lengths of my improved band, formed as described, are that the overlapped bosses at the strap edges serve to assist in withstandin g any longitudinal and lateral strain or pull upon the joint or union, while the hole 0, when the joint is completed, as specified, constitutes an aperture in the strap through which a nail o may be driven when the strap is seated upon and fastened to a box or packing-case, so that the joint of the section ends will be held rigidly and be prevented from separation.

It is evident that a box-strap constructed 5 as I have described may be bent or turned over and around the corner of a packing-box, as shown in Fig. 3, with the bend or turn formed in the Web or portion of the strap between the bosses of each series, as at b b, and too that the liability of the metal band to crack or fracture across the crown of the bosses, which is exceedingly liable to occur when there are continuous corrugations along both edges of the strap, is wholly obviated. The attainment of this result is most desirable, as the fracture of the continuous longitudinal corrugations in a box-strap produces sharp ragged edges, projecting from the strap at its angular turns on the packing-case, which are liable to damage objects with which they may come in contact and to injure the hands of the handlers, as well as causing a weakening of the strap at the places where the greatest holding strength is demanded.

It is also evident that the bands corrugated in the manner set forth and constituting the material of my improved box-strap may, when united at the ends of their sections, be reeled up or coiled helically, the webbing of hand between the bosses of each series, as set forth, permitting this coiling to be effected, and that the material thus coiled may be unreeled as desired, to be employed in binding packingcases, and may be cut or severed at the points or places where the required length of each box-strap terminates without regard to the length of the sections of band constituting the reeled strapping material, and thus all waste of material may be obviated. Metal box-straps composed of plane or corrugated bands, as hitherto formed, have been made in different lengths or sizes-the longer for large cases and the shorter for small ones; but as packingcases vary in size the straps are seldom accurately adapted to the case upon which they are bound, and hence, when too long, a waste of the unnecessary length of band is occasioned. My strap having successive bosses,

as specified, is peculiarly adapted to be united in lengths endwise, and to be, by being reeled,

put in a shape convenient for handling and to be withdrawn from the reel or coil in the exact lengths required, thus avoiding all waste or unnecessary consumption of material.

The series of successive bosses described constitute a guard for the heads of the fastening-nails by which the box-strap is secured to the packing-case, the said nails being driven through the body of the strap between the rows of edge bosses, the heads of the nails being thus prevented from abrading objects with which the strapped case may come in contact.

hat I claim as my invention, and desire to secure by Letters Patent, is-- 1. A box-strap composed of a metal band having a series of successive bosses at each side edge and extending longitudinally thereof, substantially as and for the purpose set forth.

2. A box-strap composed of a metal band having bosses of uniform shape and size and equidistant from each other in series along the side edges of the band, each individual boss in the series at one edge being respectively opposite to an individual boss in the series at the other edge, substantially and for the purpose set forth.

3. A box-strap of indefinite length composed of metal bands having similar bosses succe, sively in series throughout their length, with their ends overlapped fiatwise, with the said similar bosses fitted to each other in the respective bands and provided at or near their said lapped ends with corresponding transverse apertures, with the rims thereof clamped together, substantially as and for the purpose set forth.
