An apparatus for manipulating bars so that each face of the bar may be inspected for faults. The apparatus has a conveyor to feed a bar to an inspection table which houses angle iron members at each inspection station along the table. The angle irons engage a bar, lift it from the table, rotate it to expose its next face to inspection, and deposit it at the next inspection station. A tray is located at the end of the inspection table for unloading an inspected bar. The last angle iron deposits an inspected bar on the tray. The tray lifts the inspected bar and deposits it either on a conveyor for accepted bars, or on another conveyor for rejected bars. The unloading conveyors abut the outlet end of the table. The end segment of one conveyor is mounted to move in upward and downward directions relative to the table. When the inspected bar is to travel along this conveyor, the segment is in its downward position abutting the end of the table, and the tray will deposit the inspected bar on this conveyor. When the inspected bar is to travel along the other conveyor, the segment of the first conveyor is raised upward out of contact with the table to supply clearance for allowing the tray to deposit the inspected bar on the other conveyor.
