Abstract
A pneumatic air terminal for receiving, presenting, and dispatching pneumatically driven carriers includes a housing, a door selectively opening and closing an opening in the housing, a carrier-receiving cradle, and common drive means for opening and closing the door and for driving the cradle to a carrier presentment position, when the door is opened, and to a retracted position across the terminal from the opening when the door is closed. In an up-receive, down-send terminal, the cradle is completely retracted from the path of an incoming carrier. The carrier is stopped and is held until the cradle moves beneath it and toward the door. In a down-receive, up-send terminal, the cradle is always within the path of, and beneath, an incoming carrier, the carrier coming to rest on the cradle. Each terminal includes an abutment surface for engaging and positioning a carrier in proper position for dispatch as the cradle is driven to a retracted position.
