Abstract
Abstract An electrical dissipator comprising a multiplicity of fine electrically conductive wires having their proximate ends fitted into a hole in an electrically conductive base member and secured therein by crimping to securely grip the ends of the wires. One embodiment of the base member comprises a hollow tube allowing connection over an existing traditional lightning rod. In another embodiment, the base member comprises a solid rod or hollow tube having its proximal end threaded to allow the traditional lightning rod to be unthreaded from its threaded base and replaced. In a third embodiment, the base member comprises an apertured flange for bolting to the structure to be protected from lightning.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
An electrostatic dissipator for dissipating electrical charge from a structure to the atmosphere to minimize lightning strikes, comprising in combination: an electrically conductive base member including an upper end and a lower end; means for mounting said lower end of said base member relative to the structure to be protected; said upper end of said base member comprising an upwardly opened hole; a plurality of long fine electrically conductive metal, untwisted wires each having a proximal end and a terminal end, the proximal ends of which are bunched together to be in electrical connection with sand fitted into said hole; and means for electrically and mechanically connecting said proximal ends of said wires positioned in said hole allowing said wires to emanate upwardly therefrom in a uniform, mushroom-shaped manner.
Claim 2
Dependent Claim
129 words
An electrostatic dissipator for dissipating electrical charge from a structure to the atmosphere to minimize lightning strikes, comprising in combination: an electrically conductive base member including an upper end and a lower end; means for mounting said lower end of said base member relative to the structure to be protected; said upper end of said base member comprising an upwardly opened hole; a plurality of long fine electrically conductive metal, untwisted wires each having a proximal end and a terminal end, the proximal ends of which are bunched together to be in electrical connection with sand fitted into said hole; and means for electrically and mechanically connecting said proximal ends of said wires positioned in said hole allowing said wires to emanate upwardly therefrom in a uniform, mushroom-shaped manner.
Claim 3
Dependent Claim
26 words
The dissipator as set forth in claim 1, wherein said base member comprises a tube and wherein said hole comprises the longitudinal opening through said tube.
Claim 4
Dependent Claim
33 words
The electrical dissipator as set forth in claim 2, wherein said electrical and mechanical connecting means comprises a mechanical crimp which deforms said hole to rigidly retain and electrically interconnect said wires therein.
Claim 5
Dependent Claim
32 words
The dissipator as set forth in claim 3, wherein said lower end of said base member is threaded for threaded engagement with a mounting fixture fastened to the structure to be protected.
Claim 6
Dependent Claim
34 words
The dissipator as set forth in claim 3, wherein said mounting means comprises said longitudinal opening of said tube dimensioned to fit over a conventional lightning rod mounted to the structure to be protected.
Claim 7
Dependent Claim
46 words
The dissipator as set forth in claim 3, further including a threaded plug for insertion into said lower end of said tube and wherein said mounting means comprises threaded engagement of said threaded plug into a threaded mounting fixture affixed to the structure to be protected.
Claim 8
Dependent Claim
41 words
The dissipator as set forth in claim 1, wherein said base member comprises a rod and wherein said mounting means comprises the lower end of said rod for threaded engagement with a mounting fixture affixed to the structure to be protected.
Claim 9
Dependent Claim
31 words
The dissipator as set forth in claim 7, wherein said electrical and mechanical means comprises a mechanical crimp which deforms said hole to rigidly retain and electrically interconnect said wires therein.
Claim 10
Dependent Claim
36 words
The dissipator as set forth in claim 1, wherein said base member comprises a flange at said lower end, said flange including mounting holes allowing said flange to be mounted to the structure to be protected.
Claim 11
Dependent Claim
26 words
The dissipator as set forth in claim 9, wherein said base member is manufactured from a tube having said lower end flattened to form said flange.
