Abstract
A self-cleaning track and slidable cover for a station of a pneumatic carrier system, such as for the customer terminal of a drive-up banking system, is disclosed. The terminal cover slides along a track on the station to provide selective access to the terminal interior for insertion and removal of carriers. A temporary airflow path is defined between the bottom edge of the cover and the track through which passes pressurized air supplied to the terminal interior when the cover is closed and carrier transmission from the terminal is desired. The pressurized air passing through this path blows dirt and debris from the track which might otherwise build up and bind the sliding cover. As the air pressure in the terminal interior increases, a valve member in the form of a flexible flap extending along the airflow path moves into a position blocking the airflow path, allowing completion of pressurization of the terminal for transmission of a carrier.
