ABSTRACT:
A pneumatic carrier terminal in a preferred embodiment includes a movable horizontal tray alignable with a horizontal pneumatic tube connected to the terminal. A carrier sealing ring is provided on the end of the tray and is aligned with the tube. The trailing end of a received carrier resides in the ring which surrounds the carrier's gasket. Stationary, two-stage cam apparatus within the terminal engages and pushes a carrier out of the ring when the tray is moved out of the terminal to present the carrier. Other stationary cam apparatus within the terminal engages and pushes a carrier into the ring when the carrier is replaced and the tray is retracted from the presentment position. The ring operatively seals one end of the carrier to the pneumatic tube to positively insure carrier flight when the terminal is pressurized. Alternate cam apparatus is disclosed.
