Abstract: Lightning protection system for roofed buildings having a waste pipe system comprising a series of interconnected waste pipes, a vent stack on the roof of the building, a soil pipe at the building site buried in electrically conductive contact with the ground, a lightning rod with a ball and a space discharge electrode atop the ball, and adapted to be supported by the stack without interfering with the stack's function, the series of interconnected waste pipes being in a building wall between and connecting the vent stack above and the soil pipe below and establishing a grounding circuit including the vent stack, and a bracket carried by the lightning rod and conductively affixed to the vent stack to render the grounding circuit complete to the space discharge electrode.

Abstract: Lightning protection device of pleasing and ornamental shape and color for installation at a point on a land vehicle, particularly a point of attachment on a horizontal outside upper surface area thereof. The device comprises a charge accumulating ball with a base, a sharp pointed, space discharge electrode atop the ball, and fastening means including an electrical contact and securing together the base and the upper surface area, which area if sheet metal has the contact clamped thereto by the fastening means in electrically conductive connection to complete the circuit thereto from the electrode.
