The present application relates to fences and methods of stretching and securing fencing. In particular, the present application relates to multiple strand, interconnected, and/or mesh fencing and systems and methods for stretching, erecting, repairing, securing, and maintaining such fencing.
Welded wire and net fencing has been around for many decades. This type of fencing is manufactured by welding or intertwining wire stock to form a mesh of small openings. The openings are either the same size or different sizes over the height of the fencing. The mesh prevents small animals, live stock, and varmints from getting through the fencing. Welded wire as well as net fencing is typically sold in large, heavy, galvanized rolls. The rolls are unwound, stretched along the fence line from one end post to another, and then tied to line posts and/or T-posts to hold the fencing upright and in place.
If the fencing is not stretched properly it will sag, twist, curl, and loosen. Once it becomes loose, the animals and livestock will often push against the loosened sections, resulting in the animals and livestock being able to escape under and/or over the damaged fencing. This fencing can also become damaged by other means, including trees and branches falling on the fencing, undergrowth and brush growing through the fencing, and tractors or mowers damaging the fencing.
There are many different ways to stretch welded wire or net fencing. The fencing is usually attached to one end post, rolled out along the fence line, loosely attached to some or all of the line posts or T-posts, and then stretched to a final position. Because these rolls are usually quite heavy, it is necessary to use a truck, tractor, all terrain vehicle (ATV), or a come-along winch system to properly stretch the fencing. The stretching step usually involves attaching hooks or stretcher bars with hooks to the one end of the roll and then pulling on the hooks or stretcher bar with the truck, tractor, all terrain vehicle (ATV), or come-along. Once the fencing is stretched to the desired length, the ties holding the fencing to the line posts and T-posts are tightened, and the fencing is cut to the desired length. Then, the end of the fencing is wrapped around the end post and secured with ties, wire, or clips. Because the fencing cannot be twisted upon itself, as with barbed wire and other single-wire fencing, the fencing does not stay tightly stretched over time. There are other problems with cutting and attaching the fencing to the end posts by wrapping the fencing around the end posts. Other than being unsightly, the sharp ends of the wire stick out and can snag on users as they pass by or can cut and scrape the animals and livestock, resulting in injury to users and animals.
Although great strides in the area of stretching and installing welded wire and net fencing, many shortcomings remain.

End post 110 is preferably connected to one or more cross supports 111, such as in an H-post configuration. Although cross support 111 is depicted as a lateral support, cross support 111 can also be configured as an angled support, such as a “kicker” support. End post 110 includes an attachment surface 116 that extends from top portion 114 to bottom portion 112. Attachment surface 116 may be the exterior surface of end post 110, or may be a specially configured surface for providing a smooth transition from end post 110 to clamping member 150. Clamping member 150 is preferably attached to end post 110, such that clamping member 150 is in line with, or approximately in line with, fencing 120. This reduces the amount that clamping member 150 and fencing 120 stick out past end post 110, thereby reducing the chance that a user or animal will get snagged by clamping member 150 and/or fencing 120. Although end post 110 is depicted as the last post on the exemplary fence line, it will be appreciated that end post may be an intermediate line post along the fence line, or a corner post, as well.
Fencing 120 is preferably smooth metal strands that have been welded together or intertwined to form welded wire and net fencing; however, it will be appreciated that fencing 120 may also be nylon mesh fencing, barbed wire, chicken wire, construction fencing, erosion control fencing, or any type of elongated, continuously formed fencing material. Fencing 120 has a front portion 125, openings 126, and a rear portion 128. For purposes of explanation herein, front portion 125 represents the portion of fencing 120 that extends beyond end post 110 and clamping member 150, and rear portion 128 represents the portion of fencing 120 prior to end post 110 and clamping member 150. Openings 126 are preferably aligned vertically and laterally and are of equivalent size and shape. Alternatively, openings 126 vary in size, shape, alignment, and number found in different portions of the fence. For example, a small number of large openings 126 may be formed in a top portion of fencing 120, and a large number of small openings 126 may be formed in a bottom portion of fencing 120, whereas the large openings are larger at least in one dimension (e.g., width, height, diameter, etc.) as compared to the same dimension of the small openings.

Stretcher bar 130 preferably includes one or more notched openings 146. Each notched opening 146 includes at least one notch 148. Notched openings 146 and notches 148 are configured to receive and releasably retain the links 162 of chain 160. Preferably, notched openings 146 are vertically aligned along the length of stretcher bar 130. In addition, stretcher bar 130 may include a second set of notches 149 formed at or near top portion 134 and/or bottom portion 140, for aligning stretcher bar 130 vertically. For example, second set of notches 149 may be compared to a level or a string attached to a plumb-bob, indicating whether or not tensioning force 164 applied to stretcher bar 130 is roughly equally applied across stretcher bar 130.

Clamping bar 154 is sized and configured to be received within the channel of channel member 152. Clamping bar 154 is preferably secured to channel member 152 with a plurality of nuts 156 and bolts 158, which pass through aligned apertures 166 in both channel member 152 and clamping bar 154. Alternatively, clamping bar 154 may be secured to channel member 152 using welds, self-tapping screws, clamps, and/or other suitable fasteners. By way of another example, clamping bar 154 may be secured to channel member 152, by using nuts 156 that are permanently attached to the back side of channel member 152. This configuration reduces the number of parts and components that have to be taken into the filed. Alternatively, U-bolts, circular ring clamps, and/or combinations of fasteners may be used to secure channel member 152 to end post 110.

To stretch fencing 120, stretcher bar 130 is attached to fencing 120 by inserting hooks 142 into openings 126 and then moving stretcher bar 142 vertically until fencing 120 is engaged and retained within recesses 144. Then, stretcher bar 130 is coupled to vehicle 132 via chain 160. It will be appreciated that chain 160 should be coupled to vehicle 132, such that chain 160 is free to move, such as by rotation in the direction of arrow 157, so as to equalize tension force 164 being applied to stretched bar 130, thereby maintaining stretcher bar 130 in a generally vertical orientation. Utilizing multiple hooks 142, including up to one hook 142 for each opening 126 in fencing 120, ensures that the tension force 164 from stretcher bar 130 is distributed generally equally over the entire height of fencing 120. This reduces the chance that fencing 120 will be damaged during the stretching operation.
Although it is preferred that openings 126 of fencing 120 remain vertically aligned with clamping bar 152, it is not necessary that openings remain exactly aligned with clamping bar 152. For example, openings 126 may form a small offset angle θ with clamping bar 152. Such minor offset may be compensated for, once clamping bar 154 is bolted to channel member 152.
Next, fencing 120 is stretched past end post 110 and channel member 152. Then, clamping bar 154 is secured to channel member 152 using nuts 156 and bolts 158. This securely sandwiches fencing 120 between channel member 152 and clamping bar 154. Alternatively, clamping bar 154 may be secured to channel member 152 using welds, self-tapping screws, clamps, and/or other fasteners. By way of another example, after tensioning force 164 is applied, clamping bar 154 may be secured to channel member 152 by using bolts 158 that are received by nuts 156 that have been welded to the back side of channel member 152. At this step, any angle θ existing between openings 126 and end post 110 that occurred during the stretching process may be reduced and/or removed.
Once fencing 120 has been stretched and secured to end post 110 by clamping member 150, the tension in chain 160 may be removed and stretcher bar 130 may be removed from fencing 120. Then, any excess fencing 120 may be removed by a cutting device 450, such as wire cutters, grinders, saws, or other suitable wire cutting devices. It is preferred that fencing 120 be cut off as close to channel member 152 as possible to eliminate any wires from sticking out.

Although only two clamping members 950a and 950b are shown, it will be appreciated that more clamping members may be utilized. For example three clamping members may be used to form a T-shaped connection of fencing. In addition, although clamping members 950a and 950b have been shown to “in-line” with each other, clamping members 950a and 950b (and any other clamping members) may be at different angles to each other. This is particularly useful when the sections of fencing being stretched and joined do not form right angles to each other.

Stretcher bar 1130 preferably includes one or more notched openings 1146. Each notched opening 1146 includes at least one notch 1148. Notched openings 1146 and notches 1148 are configured to receive and releasably retain the links 162 of chain 160 (see
Stretcher bar 1130 includes at least one additional aperture 1166 disposed along stretcher bar 1130 to reduce weight. Although apertures 1166 have been shown as being generally triangular in shape, it will be appreciated that apertures 1166 may have any shape and/or configuration. It is preferred that apertures 1166 reduce the weight of stretcher bar 1130 without adversely affecting the strength of stretcher bar 1130.
It is apparent that an invention with significant advantages has been described and illustrated. Although the present application is shown in a limited number of forms, it is not limited to just these forms, but is amenable to various changes and modifications without departing from the spirit thereof.
