Electrical induction apparatus with resiliently supported magnetic core

Claim 1

AN ELECTRICAL INDUCTION APPARATUS COMPRISING A PLURALITY OF LAMINATIONS DISPOSED TO FORM A MAGNETIC CORE HAVING A CENTRAL WINDING LEG AND OUTER LEGS AND FORMING A CLOSED MAGNETIC CIRCUIT, AT LEAST ONE COIL ASSEMBLY DISPOSED ON SAID CENTRAL WINDING LEG, SAID MAGNETIC CORE HAVING A PAIR OF OUTER SURFACES DEFINED BY THE OUTER LAMINATIONS OF SAID CORE, SAID COIL ASSEMBLY BEING DISPOSED ABOUT SAID CENTRAL WINDING LEG SO AS TO EXTEND OUTWARDLY FROM SAID SURFACE, A PAIR OF CLAMPING ELEMENTS ADJACENT TO SAID OUTER LAMINATIONS, A RESILIENT SPACER INTERPOSED BETWEEN EACH OF SAID CLAMPING ELEMENTS AND SAID SURFACES OF SAID OUTER LAMINATIONS, A PLURALITY OF STRAPS DISPOSED ALONG THE EDGES OF SAID LAMINATIONS AND RIGIDLY ATTACHED TO SAID CLAMPING ELEMENTS TO HOLD SAID CLAMPING ELEMENTS IN COMPRESSIVE FORCE EXERTING RELATIONSHIP WITH SAID LAMINATIONS AND SAID AFOREMENTIONED RESILIENT SPACERS, A PLURALITY OF RESILIENT SPACERS INTERPOSED BETWEEN SAID STRAPS AND THE EDGES OF SAID LAMINATION STACK, SAID STRAPS MAINTAINING ALIGNMENT OF SAID LAMINATION STACK AND SAID RESILIENT SPACERS PROVIDING A RESILIENT SUSPENSION FOR SAID MAGNETIC CORE AND COIL ASSEMBLY AND SUBSTANTIALLY ISOLATING AND DAMPENING MAGNETOSTRICTVIE VIBRATIONS ORIGINATING IN SAID MAGNETIC CORE.
