Abstract
Abstract A powder collector having spaced parallel walls, one wall having at least one discharge opening. Three triangularly-positioned rods between the walls form a cage to retain a cartridge. A cartridge is positioned in the cage between the walls with an open end surrounding the opening in the wall. A screw in the wall opposite the opening presses the cartridge and a gasket between the cartridge and the wall against the opposed wall to seal the cartridge in the collector.
