Abstract

262,613. Beaumont, E., G. E., and Anglo American Oil Co., Ltd. Jan. 8, 1926. Fires, preventing in receptacles for inflammable liquids. - In order to prevent sparking owing to the accumulation of an electrostatic charge when a tank or other receptacle is filled. with an inflammable fluid, the tank is provided with means which automatically establish electrical contact between it and the reservoir from which it is to be supplied before the passage of fluid; or the means may be provided on the supply pipe. As shown in Fig. 2, a ring 4 mounted below the charging opening 2 of the tank 1 carries flexible conductors 5 long enough closely to engage the supply pipe a when the latter is inserted through the opening 2. The conductors 5 may be in the form of coiled wire or strips of woven wire or resilient metal. In a modification, Fig. 4, rigid U-shaped metal strips 7 are held in contact with the pipe a by a spring 9. In another modification, the pipe a engages a perforated, cupped portion of a vertically movable spring-held metal strip. In another modification, the pipe a engages a perforated, hollow, spring-held body vertically slidable in a tube secured below the charging opening. In another modification, a tube secured below the charging opening is engaged by flexible conductors carried by the supply pipe. In another modification, Fig. 14, metal bodies 31 pivoted to the pipe a fall by their own weight into engagement with the tube 30.
