Temporary electric fencing can be constructed from one or more conductors ("wires") supported by a plurality of spaced apart temporary fence posts. Typically the wire is wound onto a transportable reel so that it can be paid out when erecting the fence and wound in when dismantling the fence.

To erect say a. three wire fence the farmer will install in a spaced apart fashion the temporary fence posts.

Thus the fanner will carry a quantity of posts and walk along the proposed fence line and install the posts.

Having completed this the farmer will then anchor the reels and once again walk along the proposed fence line to thread the wires through the insulators/wire receiving apertures of the posts. When this is completed the ends of the, wires are anchored to a suitable fixture at the remote end of the fence. Finally the farmer will return to the reels to tension the fence and connect the wires to an electric fence energizer. The erection of such a temporary electric fence is thus a time consuming operation.

The object of the present invention is thus to provide an apparatus which can be used to erect a temporary fence in a more efficient and time effective manner than has hitherto been possible.

Broadly in one aspect of the invention there is provided apparatus for erecting temporary fences the apparatus including at least one reel into which fence wire can be loaded, said at least one reel incorporating an axially located bore, a mounting for mounting said at least one reel, said reel mounting comprising a hub member locatable in the bore of said reel and a hub nut engageable with said hub to cause at least partial radial , • i L !'■ ..

The term "post" as used above and throughout the following description is taken to mean any elongate member which can be located to extend substantially vertically from the ground and have engaged therewith one or a plurality of fence wires. Preferably the post is a length of glass fibre reinforced plastics material having a conventional tread-in at one end and one or a plurality of spaced apart wire receiving elements (e.g. insulators) located thereon.

In the more detailed description which follows reference will be made to the accompanying drawings in which Figure 1 is a perspective view of the carry frame without a reel or reels mounted thereon, Figure 2 is a side view of the carry frame showing reels mounted thereon, Figure 3 is a front view of the arrangement shown in Figure 2, Figure 4 is a perpsective view of the carry frame of a second form of the invention, Figure 5 is a perspective view of the carry frame of Figure 4 in combination with the reel mounting of Figure 8 being used to assemble a temporary single wire fence, Figure 6 is a part length illustration of an electric fence wire of high visibility, Figure 7 is a perspective view of a reel mounting of the general type shown in Figures 2 and 3 but designed for a single reel, Figure 8 is a cross-sectioned elevation view of a single reel located on the mounting arrangement of Figure 7, Figure 9 is a cross-sectioned end view of the mounting arrangement of Figure 7, 232470/2-2471 I 4 2o2472/ 20247- J027 Figure 10 is a sectioned elevation view of a multiple reel mounting arrangement, Figure 11 is a perspective view of an anchoring device, and Figure 12 is a plan view of the anchoring device in use.

As illustrated in Figure lthe carry frame 10 is fabricated from tubular metal of a suitable gauge atid diameter. Frame 10 comprises a cross member 11 of essentially shallow inverted V shape. Extending upwardly from the apex thereof is an upright 12 of generally inverted L shape. Flanking upright 12 are posts 13 which due to the orientation of cross member 11 are aligned and upright 12 is offset therefrom. This enables a post P to be threaded between posts 13 and central upright 12 (see Figure 1). The amount of offset of central upright 12 is preferably sufficient that posts P can snugly fit in place and thus while being readily removable are nonetheless held in place.

Extending from cross member 11 is a central member 14. Flanking this are a pair of legs 15. Central member 14 is offset from the alignment of legs 15 so that posts P can also be carried between legs 15 and central member 14.

The carry frame can be carried by the farmer thus a carry strap 16 extends between the upper end of one post 13 and the lower end of the other post 13. By passing the strap over his say right shoulder and passing across toward his left side the farmer can carry the frame with central member 14 and legs 15 extending forwardly. A more complex carry strap arrangement can be employed if required and quick release clasps, catches or the like will enable ready mounting of the carry frame on the body of the farmer. / 5 let G P 4 7 2 / 232473 f 2 3 u U 2 7 2324 7 o/2 3 2 4 71| ! Extending from one of posts 13 is a guide mount 17 in which a guide arm 18 can be inserted to extend laterally of frame 10. Guides 19 are positioned on arm 18 through which wires W cam pass. Conveniently guide arm 18 is a length of fibre reinforced plastics rod and guides 19 are insulators (of the type used on posts P) which are *adjustable in position along the'guide arm 18. Preferably the insulators will be of the type disclosed in my Australian Patent Specification 579574.

An angular cross section projection 20 forms a reel mount.

A reel support 21 has a coupling 22 with a bore of a cross section corresponding to that of reel mount 20. The coupling 22 can be fitted in a friction fit onto reel mount 20. Coupling 22 also forms a handle for carrying the reels when separated from frame 10.

A plurality of reels 23 are located on a support shaft 30 which extends from a gearbox 24. The reel support 21 extends from the gearbox as shown. A handle 25 is provided for rotation of the reels.

Projecting from gearbox 24 is an arm 26 which carries guide rings 27. A wire W from each reel 23 can pass through a respective guide ring 27 and then a respective guide 19.

The wire cam be conventionally constructed from a plxirality of plies made from insulative material filaments twisted together, these plies themselves being twisted together with filaments of metallic electrically conductive material. One of the problems associated with such electric fence wire is that of visibility. . 23 2 4 7Q/ p ot«|»«eT« Thus a wire of the type pooitod in Figure 6 can be used as it has higher visibility properties than those which have hitherto been developed. This is achieved by incorporating along the length of the wire a plurality of spaced apart flexible elements, these elements being such as to not substantially inhibit flexibility of the wire yet provide a surface area which, in use of the wire, or tape enhances visibility thereof.

As shown wire W has a plurality of plies 51 of insulative material filaments twisted together a plurality of metallic electrically conductive filaments 52.

Spaced at suitable distances along the wire are flexible elements 53 which are transversely disposed. Flexible elements 53 are located between at least a pair of adjacent plies 51 and due to the twisting of the plies are effectively located in position so as to not be able to move along wire W. In a less preferred embodiment the flexible element can be attached by physically tying to the wire or by using attachment means.

The waisting 54 caused by the flexible element being forced between the inter-twisted plies results in a desirable "crinkled" effect in surface areas 55. When, as preferred, areas 55 provide reflective surfaces the "crinkling" effect leads to a multi faceted surface which is more likely to reflect incident light than a planar surface.

Flexible elements 53 are preferably formed of a light weight and cheap material but one which is able to withstand the climatic and environmental conditions in which electric fence wires are used. Thus the flexible element 53 can be a strip of clear plastics material^to which is applied a metallized surface. This is.^-tjjen , ^ ft* * *'• ' "** /'•V- •2 :-c« o I v v.

/ Zii^73/23ii02' covered by a second strip of clear plastics material. Preferably, in order to prevent delamination, the plastic strips extend beyond the edges of the metallized surface so that the plastic edges of the two strips can be bonded together. As a result the metallized surface is sandwiched within clear plastics material.

It is not necessary that areas 55 present a reflective surface as could be of a high visibility colour which possibly contrasts with the colour of the plastics plies.

An advantage of metallized surface plastics material is that it is cheap to produce, is of thin cross-section, is robust and long lasting yet does not prevent the wire from being used as conventionally where such wires are regularly wound onto and from reels.

The flexible elements can be readily incorporated in an electric fence tape in a similar manner to that of wire W.

Frame 10 normally carries three reels, however, it can carry a single, two or more reels.

Referring to Figures 7 and 8 there is shown a simple carry frame with a single reel R. The frame comprises an upright 21a with a transverse portion 21b having a handle 22a. The handle 22a is removable so that end portion 21b can be inserted into tubular mount 26 to form a single reel embodiment of the invention shown in Figures 1-3.

Reel R is mounted with shaft S from gearbox 24 using a mounting arrangement having a hub 81 which, in the preferred form is of unit construction moulded from a suitable plastics material, and is of substantially cylindrical shape. Extending from end 82 of hub 81 is one or a plurality of open ended slots 83. Slots 83 extend 8 232472 /- 2524 73 23G027 20247^232471 substantially away zrom an internal wall 84 within the hub.

Extending from wall 84 toward and preferably beyond end 82 is a sleeve 85 which has a threaded end 86. Bore 87 of sleeve 85 is preferably of tapering cross-section toward threaded end 86. Hub 81 can thus be wedged onto shaft S. Conveniently this can be achieved using a collet arrangement of the type described in my Australian patent 579574.

A hub nut 88 having a threaded bore 89 is threaded onto end 86 of sleeve 85. The hub nut has a contoured surface 90 for gripping purposes. The "leading" end of the hub nut 88 provides an inclined face 91 which locates within em internal similarly inclined surface 92 on end 82.

Hub 81 has, extending radially about its outer surface, a rib or projection 93. In the preferred form a single rib, which is at least broken by slots 83, extends about the circumferential surface but if reguired a multiplicity of parallel ribs could be provided.

The external diameter of hub nut 88 and the greatest diameter of hub 81 (this being rib 93) when in its "relaxed" position is such that the reel can be freely slid over hub nut 88 and onto hub 81. Once in position on hub 81 the hub nut 88 can be "wound in" to cau^e surface 92 to ride up stir face 91 thereby resulting in a general radial expansion of hub 81 over at least part of its length. This causes rib 93 to engage within a continuous groove 94, of similar shape to the cross-sectional shape of rib 93, in the internal wall surface of bore B. In fact as reel R is slid onto hub 81 rib 93 will partially engage in groove 94 thereby indexing the reel in correct position. 232471 232473/23b027 The inter engagement of rib 93 and groove 94 prevents reel R from any substantial axial movement on hub 81 but allows it to freely rotate. By further expanding hub 81 by nut 88 frictional engagement between hub 81 and the internal wall surface of bore B of the reel can be increased to reduce the free running rotation of reel R.

If the reel is to be removed frcim the frame hub nut 88 is merely unwound which onables radial contraction of the hub 81 to occur thereby withdrawing rib 93 from groove 94 and allowing the reel to be slipped off hub 21. Thus the reel can be installed or xemoved without the need for removal of hub nut 88.

As shown in Figure 10 a plurality of hubs 81 can be located in an end to end arrangement. This enables for the mounting of a plurality of reels.

As illustrated the non expanding ends of hubs 81 are provided with an inclined face 95 which mates within the sloping inner surface 92 of the next adjacent hub 81.

While each hub 81 has an internal sleeve 85 this is shorter them the arrangement shown in Figures 7 and 8. The hub nut 88 is physically coupled to hub 81 with which it engages by a flanged sleeve 96. The flange 97 of sleeve 96 locates within the mouth 98 of the hub nut and is retained therein by a press fit ring 99. A clearance is provided whereby a limited amount of axial movement (i.e. "end float") of hub nut 88 relative to sleeve 96 can take place. The other end of sleeve 96 is located in a press fit over sleeve 85. In a like manner the aforementioned hub coupled with the hub nut 88 is itself coupled to the middle hub 81 and the middle hub 81 is coupled to the other end hub 21. . /232472/ 2o2473 3^Q27 232470/ 23247 ' x^u Thus as hub nut 88 is "screwed in" it expands end 82 of hub 81 with which it is coupled, however, a "daisy chain" effect takes place whereupon the other hubs 81 are similarly expanded due to the interaction of their ends 82 with the mating "leading" end 95 of the next adjacent hub 81. Likewise when hub nut 88 is screwed out it pulls the hub 81 coupled and the "daisy chain" effect is reversed. Thus uniform expansion and contraction of hubs 81 along shaft S can take place as hub nut 88 is screwed in or out.

Shaft S is mounted with gearbox 24 and the reels R are left to free wheel during paying out of the wire. To wind in the wire, hub nut 88 is tightened up sufficiently to increase the friction level between the hubs 81 and their respective reels R such that as shaft S is rotated the hubs and reels will rotate therewith. Shaft S can then be locked, with a suitable locking arrangement, to a gear wheel which meshes with a second gear in the gear-box this second gear being turned by the gearbox handle so as to effect simultaneous rotation of the shaft and hence reels R.

Thus to erect a temporary fence carry frame 10 is loaded with a plurality of posts P. Guides 19 are located at spacings which correspond with the spacings of the insulators on posts P. The ends of the wires are then attached, preferably by an anchoring device, to a fixture at the end of the proposed fence line.

The anchoring device is formed from a suitable plastics material and is essentially moulded in one piece. The anchoring device thus comprises an end portion 61 which in use is mountable with a fixture. A pair of legs 62a and 62b extend from end portion 61 as does a pair of arms 64 one of which extends above each of the legs 62a and 62b. 23*470/ 252471 / 13 Extending upwardly from each leg is a post 65. End portion 61, arm 64, post 65 and leg 62a or 62b as the case may be defines an opening 66. Thus device 10 can be attached to a fence wire C by threading the wire between the gap formed between po&^~ 65 and arm 64 so that it locates through the pair of aligned openings 66.

A pair of abutments 68a and 68b are provided on leg 62a while a single abutment 69 is provided on leg 62b. Abutments 68a and 68b are formed with shoulders 70 while abutment 19 has a shoulder 71. Abutments 68a and 68b form a gap 72 therebetween.

Projecting transversely from the outer end of each leg 62a and 62b is a stud 73 having a flanged end 74. A pin 75 projects upwardly from each stud 73.

In use the anchoring device 10 is fastened to a fence wire as previously described. The end of wire W can then be attached in the following manner.

The end of the wire is, leaving a reasonable length of ntailn T, located in gap 72 (the gap being approximately the same as the diameter of the wire) and looped around abutment 79 so as to locate beneath shoulder 71. The wire is looped about abutment 69 by passing firstly on the inboard side thereof and then passed back through gap 72 and looped about abutment 68 following which it loops around abutment 69 in che same direction as previously but located between the previous pass of the wire and shoulder 71. The wire then passes back through gap 72 to pass under shoulder 70 of abutment 68a and finally between pin 75 and surface 76 of the free end of leg 62a. 23247(^23247ij 23247^32473 In the event that an animal comes into contact with the wire and applies a force along the wire the force will either be of such a level or at such a distance from the anchoring device that it is largely dissipated by the time it reaches the anchoring device.

The force, however, may be such that a reaction occurs bt the anchoring device whereupon the force is translated into the passes of the wire between legs 62a and 62b with the result legs 62a and 62b are drawn together against a bias of spring 77. The closest approach of legs 62a and 62b is when the inner end of abutment 69 engages between the inner ends of abutments 68a and 68b in the vicinity of gap 72. As a consequence abutment 69 wedges at least one pass of the wire engaged through gap 72 thereby wedge locking the wire against movement. In fact the more pressure applied by the animal the greater the wedging action.

When the farmer wishes to release the wire, however, a series of tugs can be applied at the reel end each tug drawing legs 62a and 62b together and then allowing them to move apart. As the legs come together tail T does not move, i.e. it is not drawn through gap 72. Upon each release of the wire, which allows the legs to move apart, no movement of the wire about abutment 68b takes place, however, tail T and that portion of the wire extending about abutment 68b and past pin 75 both move through gap 72. Thus successive tugs result in tail T of the wire moving completely through gap 72 and ultimately the wire becomes totally released.

A successive number of movements of the wire would not normally arise due to an animal contacting the wire bearing in mind that the wire is electrified and an animal would not stay in contact therewith. 232471/2324 23/i'i 0 /. 2324-73/233027 End portion 61 can have a bore 78 thereby enabling the device to be attached to a circular cross-section post or standard using the collet arrangement described in my Mew Zealand patent specification 203841/204602.

To erect a fence reels R are set so as to free wheel. The farmer then commences walking along the proposed fence line paying out the wires W and in doing so takes a post P from the carry frame and by placing it rearwardly of the guide arm 18 can thread the wires through the respective insulators. By placing the post at an angle to the wires the wires can thread between the legs of the insulators and then by moving the post substantially at right angles to the wires the wire becomes captured in the aperture defined by the legs.

When the farmer reaches the point where he wishes a post to be installed he merely places the post upright and using the tread-in installs the post in the ground. Installing of the posts can, with practise, be carried out with the farmer having to only momentarily break stride.

When the farmer reaches the end of the proposed fence line reel support 21 is removed and attached to a fixture such as a permanent fence post or the like. The wires can then be tensioned and the reels locked against rotation. Thus unlike a conventional temporary fence arrangement the farmer does not need to repeatedly move from one end of the fence to the other in order to complete erection of the fence.

To dismantle the fence the farmer can either manually release the far ends of the wires or if using the aforementioned remote release anchoring device can effect release from the "reel end" of the fence. Tj using handle / « /2;J2472 / 23*470/232471/ / 23247,3 the reels 23 are rotated to wind in the fence wires. The farmer then installs the carry frame on his person and walks along the fence line lifting the fence posts and placing them onto the frame.

In Figure 4 a modified form of the carry frame is shown. This incorporates a generally U-shaped frame member 30 which has hooked portions 31 at the upper end of each leg 32. The hooked portions can be used for supporting the carry frame 10a from a mounting on say a farm motorcycle, tractor etc.

Extending upwardly from cross-member 33 is an upright 34 which is bent to form a projecting portion 37 on which handle 35 is mounted. Upright 34 is offset from the plane in which legs 32 extend thereby permitting posts P to be loaded (see Figure 5).

Adjacent the lower end of one leg 33 is a tubular mount 36. In the preferred form the lower end of upright 34 extends iiito a transverse member 38 bent to project outwardly and to which a handle 39 is attached.

Projecting at an angle outwardly from cross-member 33 adjacent the lower end of other leg 32 is a projection 40 which is provided primarily to provide a stabilizing effect for posts when mounted in the carry frame 10a.

Frame 10a includes an elastic member 41 anchored to tubular mount 36 and has a hook 42 at its free end. This hook 42 can, for storage purposes, be engaged about projection 40. However, when the carry frame 10a is filled with posts the stretchable element 41 can be engaged about the posts with hook 42 being engaged to say extension 37 at the upper end of leg 34 or over the posts and onto the cross-member 33 to retain the posts in place. -2472/232473 /23G027 *32470/25>-47 T In Figure 5 the reel mount of the type shown in Figure 7 or 8 is attached to frame 10a and by looping his arm under cross piece 33 and grasping handle 39 the user can carry the reel and posts in a convenient manner. As the user walks along he or she can loop the insulator onto the wire (as previously described) and tread the posts into the ground to form the fence line as'depicted in Figure 5.

In a further embodiment the carry frame of Figure 4 can be attached to a three reel mount. As shown in Figures 2 and 3 three "pigtail" guides will be provided one opposite each reel, and through which a wire from the reel will pass. However, as with the arrangement shown in Figure 2 an elongate member extends outwardly from gearbox 24 in the same opening as arm 26 and in the same direction.

This elongate member can be provided with pigtails or other openings through which wires passing through guides 27 can be threaded in generally the manner shown in Figures 2 and 3. This form of the invention is, however, contrasted to the arrangement shown in Figures 2 and 3 as guide arm 18 projects directly straight out from the periphery of the gearbox 24 rather than be bent to extend at right angles to the surface of the gearbox as shown in Figure 3.

Generally when three reels are being carried there is a need to increase the carrying capacity of the frame as generally a larger number of posts will be required to form the fence line. Thus frame 10a can be modified so as to provide a central "island" located in a plane between the planes in which legs 32 and upright 34 are positioned so that posts P can be located either side of the island to thereby double the carrying capacity. / 16/23247^32473 / 23G027 2324 7 0k3 2 4 7 Y f / It is not necessary that the carry freune of any of the embodiments actually be physically carried by the user. For example it could be appropriately mounted on an all terrain farm bike or the rear of a tractor. In another arrangement a cart or trolley could be provided and have a chassis on which two or more wheels are located together with feet or legs which stablize the chassis when at rest.

A handle can be provided for the user to push the car or trolley across the ground. An upright from the chassis can fit into an appropriately shaped socket or the open lower end of central upright 12 to mount the freune on the cart or trolley. The user can then push the cart or trolley in front of him/her while carrying out the same operations as when the freune is being carried.
