Abstract

18,990. Pulsford, F. C. Aug. 12. Moving-chamber apparatus for pulverulent materials with several chambers; varying quantity measured.-A drum rotating below a hopper 3 is formed with measuring-pockets 5, which are without angles or corners. The pockets 5 are formed as grooves which are rounded at the bottom and have outwardly tapered o r inclined sides and rounded ends 6, 7. One end 7 consists of a block which may be moved along the groove to vary the capacity of the pocket.
