Intercell connectors in batteries and method of forming same

Abstract

Abstract LEAKPROOF ELECTRIC STORAGE BATTERY INTERCELL CONNECTORS PASSING THROUGH THE CELL DIVIDER WALL, AND METHOD AND APPARATUS FOR FORMING SUCH CONNECTORS BY A CAST-ON-PROCESS WHILE THE PLATES ARE IN PLACE IN THE CELLS OF THE BATTERY. THE CONNECTOR IS SLOTTED IN ITS LOWER SURFACE TO MATE WITH THE UPPER SURFACE OF THE DIVIDER WALL AND RIDGED ON ITS UPPER SURFACE TO MATE WITH A CORRESPONDING RECESS IN THE BATTERY COVER, WHICH EXTENDS DOWN TO A PARTLINE APPROXIMATELY AT THE LEVEL OF THE TOPS OF THE PLATES. THE CONNECTOR IS THICKENED THROUGHOUT THE PORTION BRIDGING THE DIVIDER WALL BY BEING TAPERED LATERALLY OUTWARDLY, AND IS SEALED TO THE DIVIDER WALL AND DEPENDING PORTIONS OF THE COVER BY CEMENTING MATERIAL, WHICH MAY BE THERMOPLASTIC. ALTERNATE FORMS ARE SHOWN HAVING A PLURALITY OF RIDGES AND GROOVES IN THE UPPER AND LOWER SURFACES OF THE CONNECTOR. THE MOLDING APPARATUS GRIPS AND INVERTS THE BATTERY CASE WITH THE PLATES IN PLACE AND THEN ELEVATES A MOLD FILLED WITH MOLTEN LEAD INTO CONTACT WITH THE LUGS OF THE PLATES TO CAST THE CONNECTOR ONTO THE LUGS AND SOFTEN THE CEMENTING MATERIAL. THE MOLD IS THEN CHILLED BY FLUID PASSING THROUGH AN INTERNAL PASSAGEWAY AND LOWERED AWAY FROM THE FINISHED CONNECTOR.
