DETAILED DESCRIPTION OF THE INVENTION
[0030] Referring to FIG. 1, the barbed-wire t-post installation holder 10 of the invention is intended to be used in stringing and installing barbed wire along a line of t-posts. The barbed-wire t-post installation holder 10 can be clipped to the t-posts before or during installation of the fence, and can be removed and re-used after the barbed wire is secured to the t-posts. The barbed-wire t-post installation holder 10 supports the barbed wire close to the position where it will eventually be attached to the t-post. The barbed wire being deployed is kept off of the ground, which avoids it becoming entangled, snagged, or fouled on vegetation, rocks, or other obstructions on the ground. The barbed wire being deployed is held such that the wire is not likely to coil up in loops. Where more than one course of barbed wire is being deployed, the barbed-wire t-post installation holders 10 prevent the separate courses of barbed wire from touching the others and becoming entangled or fouled. After the barbed wire being deployed is put in place in the barbed-wire t-post installation holders 10, it can be pulled tight before being secured to the t-posts. During the pulling and tightening process, the barbs on the wire will be allowed to pass over the barbed-wire t-post installation holder 10, as described in detail below.
[0031] Referring to FIG. 2, the barbed-wire t-post installation holders 10 do not need to be placed on every t-post. Referring additionally to FIG. 3, on reasonably level terrain the barbed-wire t-post installation holders 10 can be placed approximately every 150 feet. With t-posts spaced from 8 to 12 feet apart, the barbed-wire t-post installation holders 10 can be placed at every approximately 15th t-post. Where the standard roll of barbed wire is one-quarter mile, ten barbed-wire t-post installation holders 10 will often be sufficient for each quarter-mile course of barbed wire. As the course of barbed wire is secured to the t-posts, the barbed-wire t-post installation holders 10 can be removed to be re-used for the next roll of barbed wire.
[0032] Referring to FIG. 4, the barbed-wire t-post installation holder 10 can be used with a single course of barbed wire, or when installing one course at a time.
[0033] Referring to FIG. 5, some of the barbed-wire t-post installation holders 10 can be used in a bottom-up or 180-degree rotated orientation in circumstances where the barbed wire needs to be held down instead of up, such as installation on a slope, as shown.
[0034] Referring to FIG. 6 and FIG. 7, the barbed-wire t-post installation holder 10 provides a holder body 1 having t-post clips 2 allowing the barbed-wire t-post installation holder 10 to be snapped onto and off of a t-post. The t-post clips 2 are at the nominal back of the holder body 1. A post-stud notch 3 is provided at the nominal back of the holder body 1 and is meant to fit over and enclose a portion of a stud on the t-post, for the purpose of providing additional lateral stabilization when barbed wire is being pulled and stretched through the barbed-wire t-post installation holder 10. This stabilization can be achieved by enclosing an approximately one-half portion of the post stud, as shown, or a larger portion can be enclosed. An extending support structure 4 extends toward the nominal front of the holder body 1, as shown, providing a structure to support the barbed wire being deployed. The tapering structure shown, with a wider base toward the back of the holder body 1, provides additional lateral stabilization and provides additional material so that the removal of material for the post-stud notch 3 does not weaken the structure. A transverse trough or notch is provided through the extending support structure 4 to accommodate the barbed wire being deployed. Chamfered edges 5 are provided on the trough or notch for the purpose of facilitating the passing of the barbs on the barbed wire over a saddle surface 6, as disclosed in more detail below.
[0035] Referring to FIG. 8 and FIG. 9, the post-stud notch 3 fits over a portion of a stud on the t-post and provides additional lateral stabilization against the force of the barbs on the barbed wire being pulled through the barbed-wire t-post installation holder 10.
[0036] Referring to FIG. 10 and FIG. 11, the taper of the extending support structure 4 allows for greater stability at the nominal back of the holder body 1 which is in contact with the t-post, and an amount of temporary deformability toward the nominal front when in use. The chamfered edges 5 reduce the angle of the edge encountered by the barbs of the barbed wire as it is being pulled and stretched through the barbed-wire t-post installation holder 10.
[0037] Referring additionally to FIG. 12 and FIG. 13, one or more steps of chamfer can be provided, such as the two-step chamfer shown. An advantage of the multi-step chamfer is the avoidance of presenting a single large, chamfered face for an oncoming barb to dig into and become embedded, but rather presenting a series of faces forming incremental ramps. The chamfer should be sized such that the barbs of the barbed wire being pulled through the barbed-wire t-post installation holder 10 will contact the chamfer and not become caught on the outer surface of the extending support structure 4. For most barbed wire, a chamfer extending at least ⅜ inch, or 1 centimeter should be sufficient. Between the two chamfered edges 5 is a saddle surface 6 which supports the barbed wire during the installation process. The width of the saddle surface 6, which tapers as shown, should be sufficiently wide in the middle section such that when the leading tip of a barb is being pulled across the saddle surface 6 after being pulled up over the chamfered edge 5, that leading tip of the barb does not run off of the saddle surface 6 and start lowering until after the other tips of the same barb are also at the level of the saddle surface 6.
[0038] The barbed-wire t-post installation holder 10 can be made of a plastic or rubber having sufficient hardness while still allowing the temporary deformations of the material required to snap the t-post clips 2 onto and off of the t-post, and to allow temporary deformation of the extending support structure 4 when a barb is pulled across. High-density polyethylene (HDPE) has the proper strength-to-density ratio and is also somewhat self-lubricating, which is an advantage here.
[0039] Referring to FIG. 14, in use, when a length of barbed wire to be deployed is resting upon the barbed-wire t-post installation holder 10, or when a non-barbed section of the wire is being pulled across, the wire rests upon or slides across the saddle surface 6 of the extending support structure 4. If the barbed wire is sufficiently taught and ready to be secured to the t-post, then the barbed-wire t-post installation holder 10 can be removed and the barbed wire can be secured to the t-post, usually with a metal wire tie. The removed barbed-wire t-post installation holder 10 can be re-used for later installations or later phases of the installation.
[0040] Referring to FIG. 15, in use, when a length of barbed wire to be deployed is being pulled across the barbed-wire t-post installation holder 10, such as when pulling the wire taught for installation, the oncoming barb contacts the chamfered edge 5, and not the side of the extending support structure 4, where it would likely encounter too much resistance and would instead dig in. As the barb applies transverse linear force against the chamfered edge 5 of the extending support structure 4, that force is countered by the grip of the t-post clips 2 against the t-post, and additionally by the stud of the t-post partially enveloped by the post-stud notch 3. The barbed-wire t-post installation holder 10 transfers some of the linear force into torsional force upon the t-post itself, and the t-post will deflect somewhat in response both the linear and the torsional forces. The deflection of the t-post alters the effective angle of contact between the barb and the chamfered edge 5 of the extending support structure 4, promoting the sliding of the barb as opposed to its digging into the chamfered edge 5. In addition to the deflection of the t-post, the extending support structure 4 will also deflect somewhat, further altering the angle of contact and further promoting sliding of the barb.
[0041] Referring to FIG. 16, in use, after a barb on a wire that is being pulled across the barbed-wire t-post installation holder 10 has been pulled up over the chamfered edge 5, which has been deflected to promote this action, the torsional force on the t-post and the transverse force on the extending support structure 4 relax and the t-post and barbed-wire t-post installation holder 10 return to an undeflected position, while the barb of the barbed wire to be deployed slides across the saddle surface 6 of the barbed-wire t-post installation holder 10.
[0042] In use, under many conditions, the barbed-wire t-post installation holder 10 is likely to provide a ratcheting effect during pulling and tightening of barbed wire for fence installation, because moving a barb up over a chamfered edge 5 usually requires the application of enough pulling force to temporarily deflect the t-post and the extending support structure 4. After the barb passes and the t-post and extending support structure 4 return, then the barb is unlikely to slide back across the barbed-wire t-post installation holder 10 in the absence of significant pulling in the other direction. On the other hand, if a section of barbed wire were to be overtightened, then the resulting reverse pull might be sufficient to move barbs in the other direction. If this were the case, the barbed-wire t-post installation holder 10 would be serving to relieve the effects of over-tightening of the wire.
[0043] Many other changes and modifications can be made in the system and method of the present invention without departing from the spirit thereof. I therefore pray that my rights to the present invention be limited only by the scope of the appended claims.
