  • Pneumatic tube distribution system and method
    Patent number: 6659693
    Abstract: A pneumatic system for transporting a carrier includes a first transport tube coupled to a first transport station and a second transport tube coupled to a second transport station. A distributor coupled to the first transport tube and the second transport tube includes a carousel having at least one storage chamber. The carousel is rotatable about an axis to align the storage chamber with the first transport tube and the second transport tube. A source of airflow coupled to the distributor facilitates movement of the carrier through the first transport tube and into the storage chamber of the carousel, and facilitates movement of the carrier from the storage chamber of the carousel into the second transport tube. An associated method for transporting the carrier includes the step of moving the carrier from the first transport tube in a first direction into the storage chamber of the distributor.
