Automatic Glass Elevator

Automatic elevator means a passenger or freight lift operated by push buttons so that the starting, moving, leveling, holding and opening and closing of the doors is entirely automatic. Glass elevator is defined as the rapid promotion of men to upper positions in certain professions in which women comprise the majority, such as nursing. A glass pneumatic elevator uses a vacuum system that moves the elevator cab up and down between floors. This vacuum system safely lifts the cab up and brings it back down. A brake system stops the elevator cab at the desired floor.
