ABSTRACT:
An apparatus for evacuating passengers from a passenger-carrying cabin having a floor suspended above the ground comprises upper and lower plates engageable over the upper and lower sides of a vertical hole through the floor. These plates are both secured tightly in place on the respective sides of the floor in a normal position and are released in an emergency position, with the lower plate dropping away from the car. A tubular life-saving chute is secured to the floor between the sides in the hole and is folded up between the plates in the normal position, but extends from the floor toward the ground in the emergency position to allow persons to be saved to slide down through this chute. A linkage normally rigidly interconnects the two plates together, but is operated in case of fire or the like to disconnect them.
