ABSTRACT:
An improvement in apparatuses for quantitative metering of granular materials comprising: a main body having a plurality of independent metering compartments having upper and lower open ends and disposed radially around an axis; and top and bottom end plates adapted for covering the upper and lower open ends of the compartments and being rotatable about this axis, the top plate having a hole adapted for being brought into alignment with the upper open end of each compartment as this end plate is rotated, the bottom end plate having a hole so positioned as is not aligned with the hole of the top end plate and being adapted for being brought into alignment with the lower open end of each compartment as this end plate is rotated, so that, with the rotation of these end plates, a material requiring metering is fed into the compartments, one compartment after another, through the hole of the top end plate, and the metered material contained in these compartments is allowed to flow out through the hole of the bottom end plate from one compartment after another. The improvement comprises a projectable lug provided on the top end plate so as to slidably project beyond the trailing edge of the hole thereof toward the leading edge of this hole to limit the degree of area of this hole and being adapted to be maintained at any desired degree of projection.
