Claims13
A sifter for sifting granular or powdered material such as flour comprising a hollow body member formed with a first opening defining a bottom end and a second opening defining a top end, said body member including an upper portion which tapers inwardly toward the bottom end, a lower portion which also tapers inwardly to the bottom end and means interconnected between said upper and lower portions for sharply reducing the cross-sectional area defined by said body member between said portions and thereby interrupting any continuity of inward taper between said upper and lower portions, a screen positioned within said lower portion near the bottom end, an agitator positioned within said lower portion above said screen, a handle member connected at one end to the outer surface of said upper portion near the top end, the other end of said handle member being spaced from said body member, and actuating means connected to one of said members and to said agitator for actuating said agitator, wherein said actuating means extends between said body and handle members and in alignment with the taper of said upper portion and is spaced from said lower portion to facilitate manual actuation, and wherein said body member is contoured to nest therein at least the lower portion of an identical sifter.
A sifter for sifting granular or powdered material such as flour comprising a hollow body member formed with a first opening defining a bottom end and a second opening defining a top end, said body member including an upper portion which tapers inwardly toward the bottom end, a lower portion which also tapers inwardly to the bottom end and an intermediate portion interconnected between said upper and lower portions having an inward taper greater than that of either said upper or lower portions for sharply reducing the cross-sectional area defined by said body member between said upper and lower portions and thereby interrupting any continuity of inward taper between said upper and lower portions, a screen positioned within said lower portion near the bottom end, a rotor positioned within said lower portion above said screen, a handle member connected at one end to the outer surface of said upper portion near the top end, the other end of said handle member being spaced from said body member, and actuating means including an actuating arm connected to one of said members and operatively connected to said rotor for actuating said rotor, wherein said actuating arm extends between said body and handle members and in alignment with the taper of said upper portion and is spaced from said lower portion to facilitate manual actuation, and wherein said body member is contoured to nest therein at least the lower portion of an identical sifter.
