Abstract of the Disclosure Disclosed is an operator for a door mounted by frame means so as to be slidable along a track between open and closed positions. The door has a peripheral edge which is engaged to provide a positive locking of the door. The operator includes a shaft rotatably mounted alongside the door. A locking pawl is mounted to the shaft for rotation therewith so as to be movable between an unlocked position remote from a door edge and a locked position overlying the door edge so as to block the opening thereof. A lockout lever is also attached to the shaft for rotation therewith, and is movable between an idle position whereat the shaft is rotated to bring the locking pawl to its unlocked position and a lockout position whereat the shaft is rotated to bring the locking pawl to its locked position. An emergency lever is attached to the shaft for rotation therewith, and is movable between an idle position whereat the shaft is rotated to bring the locking pawl to its locked position and an open position whereat the shaft is rotated to bring the locking pawl to its unlocked position. A spring and a pneumatic actuator move the shaft back and forth in opposite directions of rotation so as to move the locking pawl between its locked and unlocked postitions.
