ELECTRICAL PROTECTION FOR OIL STORAGE.

Application filed May 3, 1926.

This invention relates to a method and cans for protecting Oll storage reservoirs tr he dangers of confiagration through stof electricity. The objects ot 5 th. ention are to provide a method and e practicable and etl'ective charges of any nature whether thin the oil body, gas blanket or irrounoing media, and occasioned through ;;.iictional or induction influences or direct stroke of l ghtning.

Briefly st ted, my method comprises surrounding and penetrating the container and its contents with a great number of electrical conductors forming a single grounded system and wl ereby the equipotential condition of the reservoir and its contents is maintained and any unbalanced electrical stresses prevented.

The drawings accompanying this application are diagrammatic representations of my system of electrical conductors applied to an oil storage reservoir, Fig. 1 being a sectional 25 elevation of anoil storage reservoir equipped as outlined above, and Fig. 2 is a plan view oi the same.

In the drawings the reservoir 1 is pre-.

sented as of concrete imbedded in the earth 2, tho it to be understood that my system applies to oil storage reservoirs 01 any type or size holding a supply oi any kind of oil, whether some he crude, refined, or gasoline.

The reservoir is covered by a root preferably of wooden construction and which root in large reservoirs is suitably supported in the usual way on posts not shown.

liithin the reservoir passing through the bot oi oil and grounded at their lower are spaced electrical conductorso preferably made of piping, while extending horizontally throughout the reservoir within the oil l and blanket 6 are conductors 7 also grounded at. their ends and electrically secured to the vertical conductors 5 preterably by welding, tho it all are of piping, screw fittings may be used to form the joints.

An additional net-work t conductors is secured to the under side of the reservoir cover as at 8 all welded together and to the vertical conductors 5, While the outer surface of Serial N0. 106,426.

the cover is preferably sheathed with metal as at 9 also electrically secured to the vertical conductors 5.

The surface conductors both on the inner and outer surface of the cover may consist of heavy wire mesh in place of solid sheathing if desired, and the vertical conductors extending through and above the cover, or root 3 supports an additional network of conductors 10 over and beyond the entire reservoir further supported by other vertical posts, preferably grounded conductors, ll electrically connected to the elevated network and ei'fectively grounded at many points as at 12.

By thus forming a grounded gridiron of conductors completely surrounding and penetrating everywhere the reservoir, oil body, gas blanket, and surfaces or" relativc ly dielectric stratas, the possibility of accumulated electrical potential; with danger o1? disruptive discharges; is entirely avoided either within the oil through pumping or other frictional movement, or at any point through outside electrical disturbances.

I claim:

1. In the storing of oil and its liquid products, the provision of a network of grounded electrical conductors above the entire area of the reservoir, and extensions of the conductors passing through the oil within the reservoir.

2. In the storing of oil and its liquid products, the provision of a network of grounded electrical conductors above the entire area of the reservoir, and extensions of the conductors passing through the oil ithin the reservoir, and an additional layer of conductors on the root of the reservoir electrically connected to the aforesaid conductors.

In the storing of oil and its liquid prod ucts, the provision of a network of grounded electrical conductors above the entire area of the reservoir, and extensions of the conductors passing through the gas blanket and oil within the reservoir, and additionally grounded through the reservoir so as to bring all to substantially equipotential condition.
