Pneumatic tube banking system
 A pneumatic tube system for conducting banking transactions with a non-captive carrier traveling between a bank teller terminal in a two-tube carrier conveyor connected with a remote customer terminal with visual communication between the teller and the customer. The terminals and tube structure and their components are combined, interrelated and cooperatively arranged with simple and inexpensive construction to provide quiet and reliable operation. Prior complex carrier delivery and dispatch holding and release devices and blower operating timers and controls are eliminated. The operation of a blower located at the customer terminal, which supplies air for pressure or vacuum movement of the carrier in the two-tube system, is controlled by carrier arrival at or dispatch from either terminal. Noise emanating from air currents in the system is reduced by mufflers located at the terminals in the tube system. The carrier moves through one of the mufflers during travel. The terminals are readily accessible for repair of contained devices.
