Abstract

A line work tool device and method, wherein a tool guidance structure is provided for tool positioning assistance relative to the target workpiece, such as a high voltage switch, and wherein a unique inverted “L” shaped member extends from the device in such a manner as to facilitate interaction with the switch barrel.

Claims (22)

1. A method of disconnecting a switch, comprising the steps of:

a) obtaining a disconnect tool comprising a central body member with a U-shaped distal end, an L-shaped hook arm with a flanged tip, and a pole mount structure;

b) obtaining an elongated pole;

c) mounting said disconnect tool to said elongated pole;

d) extending said disconnect tool over a user's head with said L-shaped hook arm facing the user, facing away from the front of the closed cut-out switch barrel, and said U-shaped distal end proximate the front of the closed cutout switch barrel;

e) transversely engaging said U-shaped distal end of said disconnect tool with the front of the cut-out switch barrel;

f) sliding said disconnect tool in an upward direction along the front of the cut-out switch barrel to a position proximate the disconnect ring;

g) twisting said elongated pole, thereby twisting said disconnect tool, wherein said U-shaped distal end of said disconnect tool remains engaged with the cut-out switch barrel, and wherein said flanged tip of said L-shaped hook arm extends through the disconnect ring;

h) disconnecting the switch by exerting a pulling force on the disconnect ring via said L-shaped hook.

2. The method of disconnecting a switch of claim 1 , wherein said disconnect tool further comprises a prong member extending outwardly from a side of said central body member.

3. The method of disconnecting a switch of claim 1 , wherein said disconnect tool further comprises a claw member extending outwardly from a side of said central body member.

4. The method of disconnecting a switch of claim 3 , wherein said claw member comprises a plurality of apertures defined therethrough.

5. The method of disconnecting a switch of claim 1 , wherein said disconnect tool further comprises a prong member and a claw member, said prong member and said claw member opposingly extending from said second end of said central body member, proximate said tool guidance structure, together defining a T-shape for said central body member.

6. The method of disconnecting a switch of claim 1 , wherein said central body member of said disconnect tool defines an elongated central aperture.

7. The method of disconnecting a switch of claim 1 , wherein said pole mount structure is a pressure-ball system.

8. The method of disconnecting a switch of claim 1 , wherein said pole mount structure is a threaded system.

9. A line work tool, comprising:

a generally T-shaped, essentially planar body defined by a crosspiece member and a base member, each said member having a front surface and a rear surface, said base member extending outwardly from a generally central point of said crosspiece member,

wherein said base member has a bottom end and a top end, said top end defined proximate said crosspiece member and said bottom end defining a mount structure for receiving an extension pole;

a finger-like structure protruding outwardly from said plane of said front surface of said generally T-shaped, essentially planar body, proximate the point of intersection of said base member and said crosspiece member; and

a crescent-shaped guide centrally defined in said crosspiece member opposite said point of intersection of said base member and said crosspiece member, and relative to said finger-like structure such that engagement of said crescent-shaped guide with the front surface of a closed fuse body positions said rear surface of said generally T-shaped, essentially planar body proximate the front surface of the closed fuse body, such that slidable movement of said generally T-shaped, essentially planar body along the length of the front surface of the closed fuse body is enabled via said crescent-shaped guide, such that rotational movement of said generally T-shaped, essentially planar body via said crescent-shaped guide relative to the closed fuse body positions said finger-like structure through the pull ring of the closed fuse body, such that the plane of the pull ring is essentially perpendicular to the plane of said generally T-shaped, essentially planar body, and such that delivery of a pulling force to the pull ring via said finger-like structure so positioned opens the fuse body,

and wherein rotational movement of said generally T-shaped, essentially planar body relative to the open fuse body positions said generally T-shaped, essentially planar body in a coplanar relationship with the pull ring, such that said front surface of said generally T-shaped, essentially planar body is positioned on one side of the pull ring and said finger-like structure extends through the pull ring to a position on the opposing side of the pull ring, such that delivery of a pushing force to the pull ring via said finger-like structure so positioned removes and supports the fuse body.
