| 3 JD. {J. Draper - Frames} 119. giving independant support on 4 bridge bars. Wood Separators. These separators are very thin & delicate, the thickness being .062" (1.51mm.) & the flesh .034" (.86mm) in a wet state. Ribs are provided on one side only. Ebonite separators. These separators are of the slotted perforated type & are .017" (.43mm) thick. The separators in our Std. batteries are perforated with circular holes recently adopted by the Chloride Co as being better than the slotted type. All the separators project well over the edges of the plates. The depth allowed for collection of sediment is 1.000". Generally speaking this battery is not a good sound job. | ||
