Abstract: An input assembly, adapted to receive a quantity of material to be fed, includes a single input opening above and first and second spaced outlet openings below. An output assembly is operatively coupled to and fixedly positioned beneath the input assembly and is adapted to receive material from the input assembly for feeding through dual discharge tubes. A reciprocating assembly, located between the input and output assemblies, includes first and second chambers. A drive mechanism is adapted to reciprocate the chambers between a first orientation where the first chamber is being filled while the second chamber is being discharged and a second orientation where the second chamber is being filled while the first chamber is being discharged.
