Abstract: A metering arrangement for powdered material, particularly powdered beverage ingredients, includes a storage container (18), an outfeed box (22) located beneath the storage container and having an outfeed opening (46), and a reciprocatingly movable outfeed slide (60). The outfeed slide and the outfeed box are embraced by a rubber band (78), for returning the outfeed slide. The outfeed slide co-acts with a motor (36) drivingly operating the slide (40) having an L-shaped cut-out (100) in which a slide driver (94) eccentrically mounted on the crankshaft (92) of the motor is intended to move. When dispensing a metered quantity of powder, the slide driver moves in the transverse leg of the L-shaped cut-out during a first half of a revolution so as to draw out the operating slide (40) and the outfeed slide (60).
