Abstract

156,424. Barron, N. M. Oct. 1, 1919. Upward-current classifiers.-Sand-washing and elevating apparatus used in filtering-plant comprises a series of buckets P connected by pipes Q fitted with injectors R' to which water under pressure is supplied from a chamber R<1>. Water for washing is supplied through pipes o<2>, o<3> to the bottom of each bucket, overflow from the buckets passing away through pipes P<1>.
