Abstract
1358724 Earth electrode; lightning conductor ENERGLYN, RT HON LORD 5 Dec 1972 [7 Sept 1971] 41619/71 Heading H2C An electrode, e.g. an earth electrode or lightning conductor comprises an elongate metal shank 18, e.g. of iron or steel with a tapered end portion 2, radially extendible members, e.g. frusto-conical discs 8 with radial slits on the shank between a movable abutment 14 and a fixed abutment, e.g. a shoulder 6 on end portion 2, means, e.g. a nut 16 on a threaded portion of the shank to move the displaceable abutment 14 towards the fixed abutment 6 and thus radially extend members 8 and a water absorbing material, e.g. carbon, silica gel, calcium chloride, or alumina arranged about and in contact with the shank 18. As shown annular metal cup members 12 are positioned between the discs 8 and contain the water absorbing material; the cups may be internally painted with an electro-chemical conductive paint. When used as an earth electrode the shank is driven into the ground and then the nut 16 is tightened to radially expand discs 8 and cause them to make good contact with the ground. The material in the cups absorbs moisture and provides good electrical contact between the shank and the ground. The device may be used as a lightning conductor and be connected to a similar device embedded in the ground.
