REENFORCING GIRTH.

Application file'd March 15, 1920. SeriaLNo. 365,952.

To all whom it may concern:

Be it known that I, JOHN W. LESLIE, a citizen of the United States, residing at Evanston, in the county of Cook, State of Illinois, have invented an Improvement in Reenforcing Girths, of which the following is a specification.

This invention relates to reenforcing girths for use in forming jointsin metallic tensional box binders, known as box strap, or the like; and has for its object the production of a girth of simple and economical construction, and having advantages in its application and use hereinafter more specifically pointed out.

In the drawings which constitute merely an illustrative embodiment of the invention:

Fig. 1 is a perspective view, partly in cross section, showing my new reenforcing girth in the process of being applied to 11mtually overlapped strap ends.

Fig. 2 is a cross sectional view showing the girth as applied to said strap ends, prior to the joint forming operation,

Fig. 3 is a view similar to Fig. 2, showing the girth at a succeeding stage in the jointforming process,

Fig. 4 is a side viewof a joint formed with my reenforcing girth,

Fig. 5 is a plan view of the joint, and

Fig. 6 is a cross sectional view on lines 66 of Fig. 4.

In the drawings, the two ends of a binder, such as a flat tensional metallic box strap are shown in their ,relative position when the binder is applied about a box or package, with its ends 1 and 2 overlapped and superposed in alignment. The reenforcing girth herein described is applicable to said overlapped and superposed ends and serves to form an element of a joint whereby saidends are joined together.

The reenforcing girth of my invention comprises a back piece 3, shaped to accord with the upper face of the top strap 2, and of appropriate dimensions, so that the back piece 3 will lie smoothly on and make substantially complete surface contact with said top face. Formed integrally with the back piece 3 are a pair of downwardly and outwardly extending flanges 4; and these flanges are recurved as indicated at 5 to extend upwardly and inwardly (toward the interior surface of the back piece 3), and are preferably prolonged substantially so that their ends 6v extend inwardly beyond the angles 7 between the back piece 3 and the flanges 4.

It being understood that the reenforcing girth is made preferably of metal and possessed of substantial resiliency, the construction, hereinabove described afl'ords conspicuous advantages in the application of the girth upon the overlapped binder ends and simplifies materially the process of forming a joint therein.

Thus the girth may be made to embrace and maintain itself on the overlapped strap ends, without either threading it successively on the two overlapped strap ends (as would be the case if the girth were formed as a slotted tube as has been a common practice hitherto) or performing bending operations upon the girth in order to cause it to embrace the overlapped-strap ends.

In the application of my improved girth, it is simply necessary to lay the same on the overlapped strap ends with the flanges down, in the position shown in Figure 1, and subsequently to press downwardly upon it. Whereupon the recurved surfaces 5, camming over the edges of the top strap, will yield; the corners 6 will'move downwardly across the longitudinal edges of the overlapped strap ends, and as soon as they are disengaged thereby will snap in behind these edges in the position shown in Figure 2. Thus by a simple operation which can be performed in an instant the girth is applied into embracing relation with the overlapped strap ends and will maintain itself in such relation.

Further important advantages reside in the construction herein presented in that the girth is so formed and its parts have such relation to the strap ends and each other that the girth comes of itself into a substantially tight embracing relation on the strap in the succeeding oint forming operation. As an illustration; in forming a joint of the specific character disclosed in Figures 4, 5, and 6, edgewise crimping is utilized, involvin which in effect selzes the grith and enclosed strap at the edges and squeezes these edges inwardly each toward the other. Owing to the contour and arrangement of the flanges 4 and recurved portions thereon 5, it will be apparent that pressure applied inwardly upon the flange 4 will first bend this flange the application of a tool down substantially into contact with the edges of the overlapped strap; and meanwhile the edges 6 will travel inwardly along the under surface of the bottom strap. It follows that the first part of thejoint forming operation will result in the girth assuming substantiall they cross sectional shape indicated in %igure 3, wherein the girth completely embraces the strap and lies substantially in fiat contact with its surface to the full extent of the strap area the girth superimposes. At this stage the situation is the same as though an open slotted tubular reenforcirig girthhas been threaded successively onto the two strap ends.

Subsequently a continuation of the edgewise crimping operation may be utilized to produce the joint shown in Figures 4, 5, and 6, wherein conjoint interlocking deformations are produced in the girth and the enclosed overlapped strap ends; specifically edgewise crimps in the strap and girth together. The final stages of the joint forming operation are effected thus "in a manner the same as that familiar where the open slotted tubular sleeve or girth of the prior art has been utilized.

It is apparent that it is not necessary to utilize the specific type of joint-forming operation Whose results are shown in Figures 4, 5, and 6, but that the pressure involved in any crimping or squeezing operation which squeezes the strap and girth horizontally or vertically (or both); will.

result in the girth being forced automatically into substantially the configurations shown in Figure 3. Thus not only is the application of the joint made more simple than hitherto; but the first stage of a strap joining operation serves also to cause the girth of my invention substantially to duplicate the well known slotted tubular girth heretofore widely in use.

Having described my invention, I claim? 1. As an article of manufacture a substantially channel-shaped reenforcing girth for tensional binders having converging portions adapted to yieldingly engage opposite edges of mutually overlapped strap ends when being applied to both overlapped ends simultaneously.

2. As an article of manufacture a reenforcing girth comprising a back member; a flange adapted to abut one edge of a box strap; a second flange opposite the first flange and adapted to yield and recover when forced over the opposite edge of the box strap.

3. As an article of manufacture, a reenforcing girth, comprising a back member; a flange adapted to engage with an edge of a box binder; an opposite flange adapted resiliently to snap over the opposite edge when the girth is pressed upon the binder to permit the application of the girth to two mutually overlapped binder ends simultaneously.

4:. As an article of manufacture a reenforcing girth andseal comprising a back member and opposite flanges said parts being constructed and arranged so that the girth is adapted to snap over and into embracing relation with a box strap when applied thereto in a direction transversely of the face plane of the strap.

5.
