ABSTRACT:
A looped strip connected to an elevator car is moved with the car and provided with floor indication cams at intervals equal to distances between adjacent landing floors. Immediately before the car already decelerated reaches a desired one of the floors, the corresponding cam engages one of two spaced switches to operate it. This instructs the car to further decelerate and the car is stopped on the desired floor upon that corresponding cam disengaging from the operated switch with the cam located between the switches in their inoperative position.
