主权项

1. An air dispenser for a printing press operable to ensure feeding of sheets of paper to the printing press comprising:
a cylindrical body having an longitudinal axis and a threaded hole in one end of the cylindrical body extended along the longitudinal axis of the cylindrical body adapted to a fastener to connect the cylindrical body to the printing press; said cylindrical body having a square neck spaced inwardly from said one end of the cylindrical body and extended along the longitudinal axis of the cylindrical body; said cylindrical body further including a cut out having a flat base located in a horizontal plane extended across the diameter of the cylindrical body along the longitudinal axis of the cylindrical body; said cylindrical body having a cylindrical boss at an end of the cylindrical body opposite the one end of the cylindrical body extended along the longitudinal axis of the cylindrical body; an elongated tube have a longitudinal passage and an end section telescoped over the cylindrical boss to close one end of the passage and connect the elongated tube to the cylindrical body; said elongated tube having a plurality of laterally spaced openings open to the passage of the elongated tube to allow laterally spaced streams of air to flow toward the printing press; an air pump operable to supply air under pressure to the longitudinal passage of the elongated tube; and an air flow regulator connected to the air pump and elongated tube operable to regulate the rate of the flow of air into the longitudinal passage of the elongated tube and the flow of air discharged from the openings to the printing press.
