Abstract: A rotary drum metering feeder device which includes an outer casing defining a generally cylindrical chamber with opposed top and bottom end plates, a rotary drum means including a generally vertically disposed central shaft journably retained within the end plates and having a plurality of generally radially disposed blades secured at their inner ends to the central shaft and at their outer ends to an outer sleeve, and defining a plurality of metering chambers therebetween. An inlet port is formed within the top end plate, and an outlet port within the bottom end plate, and with each of the ports having edge surfaces, and with the edge surfaces of the inlet port being spaced from each of the edge surfaces of the outlet plate so as to provide for closed arcuate web zones in the end plates between the ports. A wiper blade is secured to the top end plate and extends radially across the inlet port, with the inner end of the wiper blade being maintained in close running clearance with each of the chamber defining blades so as to level the charge of material contained within each of the chambers during rotation. A counter is provided for counting the number of revolutions of the drum to determine delivery volume.
