Nozzle apparatus and engagement method

摘要

An improved nozzle apparatus and method for automatic engagement with a bottom inlet. The apparatus is characterized by a frame and an upwardly-facing nozzle member carried by the frame and horizontally movable thereon into a position of vertical alignment with the inlet. In preferred embodiments, a blower creates an air ride for the nozzle member facilitating its positioning on the frame, and another blower creates a vacuum to hold the nozzle member in proper position for engagement with the inlet. The nozzle member is preferably conical in shape.
