ABSTRACT:
A mechanical linkage and switch for sensing a torn or damaged portion of a conveyor belt. The detector includes a switch enclosed in a housing and connected to a cable which extends across the bottom of the conveyor adjacent to the conveyor belt. The cable is detachably connected to the housing by a unique ball and socket arrangement, so that when a torn section of a conveyor belt engages the cable the ball is pulled from the socket to trip the switch. The housing isolates the switch from the ambient atmosphere to allow the detector to be used in an explosive environment.
