Title: The Innovative Contributions of Andrew F. Kirsch

Introduction

Andrew F. Kirsch is a notable inventor based in Edison, NJ (US). He has made significant contributions to the field of elevator systems, holding a total of 3 patents. His work focuses on enhancing the safety and efficiency of elevator operations, showcasing his commitment to innovation.

Latest Patents

One of Kirsch's latest patents is an elevator system that includes apparatus for detecting mechanical damage, such as that caused by an earthquake. This system features a cable strung in the hoistway, reeved about a plurality of sheaves carried by the counterweight. The normal operation of the counterweight maintains a predetermined tension in the cable, which is used to keep a switch in a first condition. If there is abnormal movement of the counterweight outside its vertical travel path, the tension in the cable changes, operating the switch to a second condition that modifies the elevator system's operation.

Another significant patent by Kirsch is an elevator system with multiple elevator cars and supervisory control for directing their movement efficiently within a building. This supervisory control divides the workload uniformly among the elevator cars by periodically assigning, clearing, and reassigning service directions from the floors to the cars according to a predetermined strategy. This strategy includes special treatment for assigning service directions from floors where each car will stop and depart, improving overall elevator service.
