4 Claims. i
This invention relates to electric fencing and more particularly'to an insulated bracket used in connection therewith,
The principal object of the invention is the provision of an insulated corner bracket for electric fencing.
A further object of the invention is the provision of an insulated corner bracket incorporating means for holding a fence wire in stretched posi tion.
A still further object of the invention is the provision of an insulated bracket for electrical fencing incorporating means facilitating the mounting of a bracket on steel or wooden posts.
A still further object of the invention is the provision of a method of installing an electrical fence including stretching the fence over rotatable insulators and holding each straight section of fence in stretched position while subsequent sections thereof are installed.
The electrical fence insulator shown and described herein has been designed to facilitate the construction of single wire electric fences which are commonly employed for fencing in live stock. The principal novelty in the invention resides in the formation and construction of the insulated bracket which construction enables it to be used to hold a stretched section of fence while subsequent sections thereof are erected.
With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed with- .out departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a side elevation of the insulating bracket.
Figure 2 is a cross sectional side elevation of the insulated bracket.
Figure 3 is an end elevation of the insulated bracket illustrated in Figure 1. Lines 22 on Figure 3 indicate the cross section illustrated in Figure 2.
Figure 4 is a top plan view of a section of fencing illustrating the use of two of the insulated corner brackets shown in Figures 1, 2 and 3.
Figure 5 is an enlarged end elevation of one of the insulated corner brackets illustrated in Figure 4 and shows a modification in the bracket attachment means.
Figure 6 is a front elevation of a bracket carrying an insulator rotatably mounted thereon for use in connection with the insulated corner bracket shown in Figures 1, 2, 3, 4 and 5.
Figure '7 is a cross sectional side elevation taken on lines l-'! of Figure 6.
By referring to Figures 1, 2 and 3 of the drawings it will be observed that an insulated corner bracket has been disclosed which consists of a pair of flanged base members I!) and H which support in pivotal relation thereto an inverted Ushaped body member I2. The body member i2 is pivotally affixed to the pair of flanged base members it and II by suitable means such as a bolt and nut assembly [3 as shown or a cotter key (not shown). The end portions of the U- shaped body member l2 are rounded, as indicated at E4, to provide for the partial rotation of the body member [2 about the pivot l3. Each of the flanged base members [0 and H are provided with punched openings [5 and i6, respectively, and raised loops I1 and I8, respectively, one or both of which are used in attaching the insulated bracket to a supporting means such as a fence post. The punched openings l5 and it provide for the insertion of a nail or screw and the loops I1 and I 8 provide for the passing of a wire therethrough so that the device may be wired to a metal post, The U-shaped body member H has an insulator I9 positioned in a rotatable manner, as by means of a bolt and nut assembly 20, the insulator l9 being circular in shape and having a deep annular groove formed in the periphery thereof, as indicated by the numeral 2| in Figure 3. The bolt and nut assembly l3 which forms the pivot between the body member l2 and the flanged base members It and H has an arm 22 attached thereto by means of an eye formed in one end thereof, the arm 22 being positioned between the arms of the body member [2. The outermost end of the arm 2?. is provided with a pair of upturned brackets 23 which define a channel therebetween lying on the central axis of the device and particularly in line with the deep annular groove 21 in the periphery of the circular insulator l9 thereof.
By referring now to Figures 4 and 5 of the drawings the manner of using the insulated corner bracket will be seen. In Figure 4 a section of fencing utilizing a barbed wire 24 is illustrated as positioned between a pair of corner posts 25 and 26, respectively, and a line post 21. The
insulated corner brackets are shown attached to the posts 25 and 26 by means of nails and the arm 22 of the bracket attached to the post 25 is shown holding the barbed wire 24 in stretched position as the brackets 23 on the arms 22 have been moved into position adjacent one of the barbs of the barbed wire 24 so that the stretched wire 24 is directly supported by the arms 22 and the bolt and nut assembly 13 which in turnis carried bythe flanged base members it! and II. The barbed wire is passedthrough the device in the area between the insulator I9 and the arms 22. An arrow in Figure 4 indicates the direction of installation of the fence and by referring to, the other corner post 26, as illustrated in Elgure 4, the completely stretched and installed section of the fencing may be seen to pass through the insulated corner bracket attached to the post 26 and it will be observed that the arm 22 has been disengaged from the barbed wire 24 so that the wire is supported entirely-on the insulator l9. It will thus be obvious that the arm 22 is used only during the construction of the fence I to hold each sectionof the fence-in stretched positionas itis being erected and that immediatelyafter the erection is completed thearms 22' are disengaged from the fence so that they will not cause a short when the electrical circuit is established through the wire 24.
By referring now to Figure of the drawingan enlarged detail view of the use of the insulated corner bracket is illustrated it being observed that the brackets 23 on the arms '22 of the device engage the wire 23 by meansof the barb formed thereon and thus serve to holdit. In Figure 5 the alternate method of attachment of the insulated corner bracket has been illustrated and attachment wires 28 and 29 are shown positioned through the loops IT and I8, respectively, of the flanged base members it and I l, respectively, and
passed about a metal post'30.
In Figures 4, 6 and 7 a rotatable insulated bracket has been illustrated and is'used' in connection with supporting straight sections of fencing formed with the insulated corner brackets heretofore described; -By referring to Figures 6 and 7 these rotatably positioned insulated brackets may be seen to comprise a circular insulator 3| having a deep annular groove 32 formed in the periphery thereof, the insulator being supported on a base member 33 by means of at rivet or other suitable fastener 31 and the base 33 being provided with loops 35 and punched openings 35'so that it maybe attached to either a wooden or metal post byeither nails or wires as heretofore described in connection with the insulated. corner. bracket. The rotatable insulated bracket enables the insulated corner brackets to be used in stretching the fencing wire.
It will thus be seenthat a simple and efficient insulated bracketihas been disclosed which may be advantageously" used in forming electrical fences and that the bracket not only supports and positions the fence wire with respect to supporting posts but maybe used to holdthe fencingwire in stretched position during the installation thereof;
Having thus described my invention, what I claim is:
1. An insulated corner bracket for electrical barbed wire fencing including a pair of flanged base members having a U-shaped bracket pivotally attached thereto, a circular annularly grooved insulator positioned in the said bracket, and an arm pivotally attached at one end to the said base members and having wire engaging means formed on the other end thereof, the said wire engaging means comprising spaced brackets projecting from the said arm.
2. An insulated corner bracket for electrical barbed. wire. fencing including at least one base member, an insulator mounting bracket pivotally attached thereto, a circular annularly grooved insulator positioned in the said bracket and an arm. pivotally attached at one end to the said base" member and having wire engaging means formed on the other end thereof, the said wire engaging means comprising spaced relatively short secondary arms projecting from the said arm at right angles thereto.
3. An insulated corner bracket for electrical fencing including a flanged base member, an insulator mounting bracket pivotally attached thereto, a circular annularly grooved insulator rotatably positioned on the said bracket and spaced with respect to the said base member, and an arm pivotally attached at one end to the-said base member and having wire engaging" means formed onthe other end thereof, said'wire-engaging means comprising a bifurcated section'on the said arm formed at right angles thereto;
'4. An insulated corner bracket for electrical barbed wire fencing comprising a'pairofflanged base-members, a-pivot member engaging'the said flanged base members, a U-shaped bracket engaging the said pivot member, a secondary pivot member positioned through said U-shaped bracket, an insulator positioned on said secondary insulator in the U-shapedbracket, an arm pivotally attached to the first mentioned pivot member; the said arm having an end portion U-shaped in cross section and defining a-bifurcated portion atright angles to the plane of the said'arm.
