Abstract: A discharger mechanism is disclosed for discharging solids from the bottom of a pile. The discharger has a single reciprocating stoker rod and thus avoids misalignment and distortion so common in two reciprocating stoker rod discharger mechanisms. The discharger has a single stoker rod extending beneath a pile, one end of the rod being a discharge end, a reciprocating means reciprocates the stoker rod longitudinally. A plurality of stoker cross bars, substantially perpendicular to the stoker rod, are equispaced apart and rigidly attached at their centers thereof to the stoker rod, each of the cross bars has a wedge shaped cross section with a vertical surface facing towards the discharge end and an upward sloped surface facing away from the discharge end at an angle less than 45.degree..
