Abstract: AN ELECTRICAL CIRCUIT INTERRUPTER HAS A MOVABLE CONTACT CARRIED BY A CONTACT OPERATING MEMBER FOR MOVEMENT RELATIVE TO STATIONARY CONTACTS BETWEEN CLOSED AND OPEN CIRCUIT POSITIONS. OPERATING MEANS WILL MOVE THE OPERATING MEMBER FROM CLOSED TO OPEN CIRCUIT POSITION UPON RELEASE OF LATCHING MEANS ENGAGED THEREWITH. THE CONTACT OPERATING MEMBER CARRIES AN ARMATURE WHICH IS SUBJECT TO THE MAGNETIC ATTRACTION OF A SOLENOID COIL SO AS TO BE MOVABLE TO OPEN CIRCUIT POSITION UPON PASSAGE OF A SHORT CIRCUIT CURRENT OF PREDETERMINED MAGNITUDE THERETHROUGH. A SECOND ARMATURE ALSO ACTED UPON BY THE MAGNETIC FIELD OF THE SOLENOID COIL IS MOVABLE INTO A CIRCUIT OPENING POSITION UPON PASSAGE THROUGH THE SOLENOID COIL OF A LESSER SHORT CIRCUIT CURRENT AND ACTS UPON THE LATCHING MEANS DURING SUCH MOVEMENT TO RELEASE THE OPERATING MEANS FOR AUTOMATIC OPERATION THEREOF.

THE BIASING FORCE ACTING UPON THE SECOND ARMATURE AND WHICH MUST BE OVERCOME BY THE SOLENOID FORCE FOR TRIPPING MAY BE PRECISELY ADJUSTED AND THE AIR GAP BETWEEN THE SECOND ARMATURE AND SOLENOID COIL MAY ALSO BE ADJUSTED WITHOUT VARYING THE BIASING FORCE BY MEANS OF A PAIR OF PIVOTABLY INTERCONNECTED ADJUSTMENT LEVERS WHICH ARE PIVOTABLE AS AN ASSEMBLY TO VARY THE AIR GAP.
