Patent ID: 7318690

Claim:
Apparatus comprising: an up receive/down send terminal adapted for operative connection with an end of a pneumatic transport tube, wherein the terminal is adapted to selectively receive a pneumatic carrier therein and to send a pneumatic carrier therefrom, the terminal comprising: a frame; a door assembly having a rotatably mounted door member rotatable about a substantially vertical axis, wherein the door assembly is mounted in operatively supported connection with the frame, wherein the door assembly is operative to selectively open and close a carrier access opening through which a user can access the carrier; a tubular portion in operatively supported connection with the frame and extending generally vertically within the terminal, wherein the tubular portion is in operative connection with the end of the pneumatic transport tube; a catch assembly mounted in operatively supported connection with the frame, wherein the catch assembly is selectively operative to cause at least one catch to extend inwardly in the tubular portion, wherein the inwardly extended catch prevents a pneumatic carrier from moving downward within the terminal.
