Lamp failure indicator
Abstract
Abstract APPARATUS FOR INDICATING WHEN ONE OF SEVERAL ELECTRICAL LOADS HAS CEASED TO DRAW CURRENT. CERTAIN LOADS ARE ENERGIZED THROUGH A FIRST BIMETAL MEMBER AND OTHER LOADS ARE ENERGIZED THROUGH A SECOND BIMETAL MEMBER, THE MEMBERS BEING POSITIONED SO THERMAL FORCES GENERATED THEREIN MOVE THEM IN OPPOSITE DIRECTIONS. AN INSULATING SPACER MEMBER CONNECTING THE MOVABLE SECTIONS OF THE BIMENTAL MEMBERS PREVENTS THEIR MOVEMENT UNTIL THE FORCES BECOME UNEQUAL. THE BIMETAL MEMBERS THEN MOVE IN THE SAME DIRECTION UNTIL THE ONE IN WHICH THE GREATEST FORCE IS GENERATED ENGAGES A CONTACT MEMBER CONNECTED TO AN INDICATOR DEVICE. CURRENT DRAWN BY THE DEVICE TENDS TO FACILITATE THE ELECTRICAL CONNECTION WITH THE CONTACT MEMBER.
