Abstract
Abstract An easily installable and adjustable device for preventing electrolytic corrosion in boilers and other types of deleterious water action, including formation of scale and foaming. The device comprises a metallic iron grid, connected to two upstanding metallic arms provided with spaced regularly appearing perforations or holes. The ends of the arms are adapted to be bent over and broken off at the desired lengths and simply bolted through a brass bolt to the boiler shell, with provisions for connecting a ground cable to the bolt for grounding.
