ABSTRACT:
A pneumatic transmission system has a customer terminal, a teller terminal and a transmission tube connecting the terminals. A pair of blowers are disposed in the transmission tube. Each terminal has a slide gate which is operable to close the transmission tube, and a catch disposed below the gate which is operable to catch the pneumatic carrier. The carrier is transmitted from one terminal to the other terminal by opening the gate of the one terminal, closing the other gate of the other terminal, and energizing the blower remote from the one terminal, thereby creating a vacuum between the one blower and the carrier. The one blower is de-energized after the carrier has passed the one blower, and the carrier rides down on a cushion of air, coming to rest on the gate of the other terminal. The gate of the other terminal is then opened and the carrier drops downwardly onto the catch of the terminal. A controller and timer facilitate sequencing of the slide gates and blowers.
