Abstract
Abstract A reel for electric fence wire is formed from electrically insulative material and is supported for rotation between electrically conductive arms of a grounding stake, the reel containing an energizer which is grounded through an electrically conductive shaft which extends axially through one end of the reel to provide a journal bearing for the reel, the shaft being in electrical continuity with the associated arm of the grounding stake, and extending axially into engagement with a grounding electrode of the energizer, thus eliminating a requirement for slip rings.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
An electric fencing device of the type including a hub for the storage of fence wire, support means in which the hub is rotatably supported, an electric fence energizer and a power source located within said hub for supplying electric current to said fence wire, and a grounding member for connecting the energizer to ground, the improvement comprising: said hub being formed from an electrical insulating material; said support means being formed from an electrically conductive material and having spaced arms between which said hub is journalled for rotation, one axial end of said hub being rotatably supported in one of said arms; and, a contact member carried by and in electrical continuity with the other of said arms, said contact member extending axially through the opposite axial end of said hub and supporting said opposite end for rotation relative to the other said arm; said contact member extending axially into direct contact with a grounding contact of said energizer and providing a pivotal contact between said electrically conductive support means and said grounding member of said energizer.
Claim 2
Dependent Claim
178 words
An electric fencing device of the type including a hub for the storage of fence wire, support means in which the hub is rotatably supported, an electric fence energizer and a power source located within said hub for supplying electric current to said fence wire, and a grounding member for connecting the energizer to ground, the improvement comprising: said hub being formed from an electrical insulating material; said support means being formed from an electrically conductive material and having spaced arms between which said hub is journalled for rotation, one axial end of said hub being rotatably supported in one of said arms; and, a contact member carried by and in electrical continuity with the other of said arms, said contact member extending axially through the opposite axial end of said hub and supporting said opposite end for rotation relative to the other said arm; said contact member extending axially into direct contact with a grounding contact of said energizer and providing a pivotal contact between said electrically conductive support means and said grounding member of said energizer.
Claim 3
Dependent Claim
34 words
An electric fencing device as claimed in claim 1 wherein said contact member passes through one end portion of the reel, and a handle is connected to the opposite end portion of the reel.
Claim 4
Dependent Claim
25 words
An electric fencing device as claimed in claim 1 wherein said power source includes at least one battery for supplying electric power to said energiser.
Claim 5
Dependent Claim
24 words
An electric fencing device as claimed in claim 1 wherein said grounding member comprises a combination of said support means and a ground stake.
Claim 6
Dependent Claim
32 words
An electric fencing device as claimed in claim 1 wherein said support means comprises a substantially U-shaped member having arms in which the reel is supported for rotation about its longitudinal axis.
Claim 7
Dependent Claim
45 words
An electric fencing device as claimed in claim 1 wherein the reel is a hollow tubular member, and is arranged to accommodate a separate compartmentalized energizer and power source device having external contact members for connection to said fence wire and to said contact member.
