| THE ARRANGEMENT IS INTENDED FOR USE IN A CABLEWAY WHICH COMPRISES AN ENDLESS TENSION CABLE OPERABLE TO REVOLVE IN AN ENDLESS PATH, AND A PLURALITY OF CARS EACH OF WHICH COMPRISES GRIPPING JAW MEANS AND MEANS FOR OPERATING SAID GRIPPING JAW MEANS TO GRIP SAID TENSION, CABLE AND THUS TO COUPLE SAID CAR TO SAID TENSION CABLE. THE CABLEWAY FURTHER COMPRISES A SHUT-DOWN SWITCH OPERABLE TO INTERRUPT THE OPERATION OF SAID TENSION CABLE. THE ARRANGEMENT COMPRISES A TESTING LEVER CARRIED BY EACH OF SAID CARS, A TESTING RAIL DISPOSED IN THE PATH OF SAID TESTING LEVER AND ENGAGEABLE THEREBY AND ADAPTED TO APPLY TO SAID TESTING LEVER A TESTING FORCE WHICH TENDS TO IMPART TO SAID TESTING LEVER A PIVOTAL MOVEMENT IN A PREDETERMINED SENSE, AND MEANS OPERATIVELY CONNECTING SAID TESTING LEVER TO SAID GRIPPING JAW MEANS AND ARRANGED TO PRESENT TO SAID PIVOTAL MOVEMENT A RESISTANCE DEPENDING ON THE GRIP OF SAID GRIPPING JAW MEANS ON SAID TENSION CABLE. THE TESTING LEVER IS ARRANGED TO OPERATE SAID SHUTDOWN SWITCH WHEN SAID FORCE HAS OVERCOME SAID RESISTANCE. THE ARRANGEMENT FURTHER COMPRISES COMPRESSION SPRING MEANS, A WEIGHING RAIL WHICH IS SUBJECTED TO AN UPWARD BIAS BY SAID COMPRESSION SPRING MEANS AND ADAPTED TO BE ENGAGED AT ITS TOP BY EACH CAR AND TO BE DEPRESSED TO AN EXTENT WHICH DEPENDS ON THE WEIGHT OF SAID CAR AND MULTI-POSITION SWITCH MEANS ADAPTED TO CONTROL SAID TESTING FORCE IN DEPENDENCE ON THE EXTENT OF THE DEPRESSION OF SAID WEIGHING RAIL BY SAID CAR.
