ABSTRACT:
An emergency escape apparatus includes a gear track mounted vertically on an exterior surface of a building. A carriage is provided with guide rollers which engage a guide track oriented adjacent and parallel to the gear track. A gear wheel is rotatably mounted on the carriage and is maintained in positive engagement with the gear track by the guide rollers. The carriage includes automatic brakes which serve to limit the maximum downward velocity of the carriage, and a boatswain's chair is attached to the carriage to secure one or more persons to the carriage for transport down the outside of the building.
