Abstract
A pneumatic system for banking consists of a pair of upright customer and teller terminals joined at right angles at their lower ends by a carrier transit tube. Each terminal includes a carrier elevator, a blower and a special ducting such that while only one blower propels the carrier from the sending to the receiving terminal both blowers are used to raise the elevator and carrier at the receiving terminal. Air valves at each terminal influence the movement of the carrier, and various controls initiate the sequence of operations by which the carrier is transferred between the terminals.
