The two complementary parts of the adapted for Securing the ends 0f flexible tapas staple are assembled with their head portions such as are used for tennis court markers and forming a pair of closely parallel crossbars 12 like purposes and is so constructed that the tape and 13 and their right-angled portions twisted 100 may be firmly gripped without piercing its matogether to provide the legs 10. terial. It is to be understood, however, that In use, the. end 14 of. a flexible tape 15 is the present improved staple may be applied to threaded upW y thmllgh the Opening 16 pmuses other than herein specified, that is for fasvided between the bars 12 and 13. This end is tening the ends of bands or tape other than game held fast and the main length of the tape 15 is 105 markers. wrapped upwardly around one of the crossbars The customary manner of securing flexible tape and brought over to lie against the top of both markers or the like to the ground is to provide bars as shown best in Fig. 1. The tape is thus grommets in the body of the tape for receiving looped around one of the bars with its main nails or spikes driven therethrough. In addilength engaging across the top of the free end passed over the opposite bar to frictionally bind the latter thereagainst. The staple is then driven into permanent place in the ground with the crossbars 12 and 13 substantially at the ground level 1'7 as illustrated in Fig. 1.

The longitudinal pull or tension on the tape 15 results in a binding action to tighten the tape both between the adjacent surface of the crossbars 12 and 13 and against the top of the crossbar over which it passes. In laying the tape or adjusting it for stretch the slack may be taken up by pulling the end 14 through the space between the crossbars of the staple, this action being possible inasmuch as any pull on such lapped end 14 tends to free the binding engagement of the crossbars 12 and 13 with the tape. It should also be observed that this adjustment of the tape may be accomplished without disturbing the location or permanency of the anchorage of the staple.

In the embodiment of the invention illustrated in Fig. 3 the staple is constructed of a single length of wire having the intermediate portion thereof formed into one crossbar 18 and its ends bent at right-angles thereto to provide leg portions 19. The ends of the wire are then looped back to extend parallel with the leg portions 19 to provide complementary portions 20. Finally, the ends of the portions 20 are bent inwardly at right-angles to form a second crossbar 21 which lies closely parallel to the bar 18. The function of this form of staple is substantially identical with that of the one described in connection with Figs. 1 and 2, the legs formed by the wire portions 19 and 20 being adapted to be driven into the ground until the crossbars 18 and 21 lie closely parallel with the surface thereof. The lowermost extremities of the legs 19 and 20 may be twisted together as in Figs. 1 and 2 if desired.

A form of staple substantially as illustrated in Fig. 3 may be constructed from two components comprising crossbars and legs made from separate lengths of wire and assembled in overlying relationship with the ends of the leg portions electrically welded together. In such case both of the parallel crossbars would be continuous without the break shown in Fig. 3.

Fig. 4 of the drawings illustrates a further modification in the construction of the staple, showing it as formed from a length of wire bent to provide legs 22 and a connecting head portion or crossbar 23. Secured to the leg portions 22 by loops 24 are the ends 25 of a second, shorter U-shaped element which is constructed to provide a crossbar 26 adapted to extend closely parallel with the main crossbar 23. If desired, the loops 24 may be welded or brazed to the legs 22 to strengthen the structure. This latter form of construction provides the parallel crossbars 23 and 26 which engage the end of the flexible tape to function in the manner and for the same purpose as hereinbefore explained.

The present invention also contemplates the construction of a staple from sheet-metal. In Figs. 5 and 6 there is illustrated a substantially U-shaped sheet-metal staple having legs 27 and 28 connected by an intermediate head portion 29. The legs 27 and 28 may be pointed as at 30 to facilitate driving them into the ground or other surface. The head portion 29 is formed with a pair of parallel, elongated slots 31 and 32, through which the end of the tape may be threaded and held in the same manner as described in connection with the foregoing forms or embodiments of the invention. In Fig. 5 the end 14 of the tape 15 is shown as being wrapped around one edge 33 of the head portion 29 and then carried upwardly through the slot 31 and downwardly through slot 32. The extremity of the end 14 is then passed upwardly around the other side edge 34. of the head 29 and along the ground underneath the main length 15 of the tape. It will be apparent by reference to Fig. 5 that the main portion 15 of the tape will bind the end 14 against the intermediate portion 35 of the head 29 between the slots 31 and 32 to secure the end thereto while permitting the tightening of the tape by drawing it through the slots.

Figs. '7 and 8 illustrate still another modified form of sheet-metal tape-holding device comprising the novel features of the invention. This latter form comprises a single leg 36 which is sharpened at its lower end 37 and has an angularly bent flange 38 at its upper end. Immediately adjacent the juncture of the leg 36 with the flange 38 the metal is provided with a pair of parallel elongated slots 39 and 40. In use, the end 14 of the tape 15 is threaded first through the lower slot 39 and then upwardly through the slot 40 with its terminal portion caused to lie against the upper surface 41 of the flange 38. The main length of the tape 15 overlies this end 14 of the tape and the tension thereon causes it to bind the end in place.

From the foregoing it will be observed that the present invention provides an improved device which is extremely simple in construction, economical to manufacture and adapted to serve adequately to hold in taut and alined condition the ends of flexible tapes or the like. My improved staple functons to grip and hold the tape without requiring piercing the material thereof, while also permitting longitudinal adjustment of the tape without removing the staple from its anchorage. The intermediate length between the ends of the tape may be fastened in place by other staples suitably anchored to the ground, for example, by the use of single wire staples.

Various modifications other than illustrated may be made in the form and structure of the device without departing from the spirit or scope of the invention. Therefore, without limiting myself to the exact disclosures herein shown and described, I claim:
