Sifter

A sifter comprising a casing segmented into first and second segments, a screen rigidly mounted to one of said casing segments through which material introduced into said casing may be sifted, means for releasibly coupling together said first and second casing segments for limited relative movement, and a handle mounted to said screen having an end portion provided with coupling means for coupling said handle with an electric knife drive means of the type having two juxtaposed drive rods such that said screen may be driven by said drive means with a generally linear, reciprocating movement, and wherein said first casing segment has a tubular wall of a selected diameter and said second casing segment has a tubular wall of a diameter less than said selected diameter, and wherein said coupling means include a pair of circumferentially spaced tabs projecting inwardly from said first casing wall and a pair of circumferentially spaced tabs projecting outwardly from said second casing wall and guide means for positioning said first segment pair of tabs and said second segment pair of tabs into and out of overlapped sliding engagement upon one another.

A sifter comprising a tubular casing and a screen detachably mounted to said casing for limited relative movement with respect thereto, and a handle, wherein said casing has a cylindrical outer wall from which a conical inner wall inwardly extends and from which a casing ledge radially extends, and with said screen having an annular wall to which a planar screen mesh is mounted and from which a screen ledge radially extends, and wherein said handle extends radially from said annular screen wall at an axial position relative to said screen ledge to be detentable within a casing detent notch with said screen ledge slidably supported upon said casing ledge.
