Abstract
A single overhead pneumatic tube system employs a large rectangular tube, a pair of overhead mounted blowers and a large rectangular captive carrier having a pair of oppositely disposed sliding closures. The carrier is transported between two terminals, one terminal having a drawer-like carrier receiver which slides one of the carrier closures to one side as the receiver opens for access within the carrier by a teller. The other terminal includes a carrier receiver whose front swings open and tilts the carrier outwardly whereupon the other carrier closure is slid to one side for access within the carrier by a customer.
