Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
76 words
THE METHOD OF CASTING BATTERY POST STRAPS ONTO THE CONNECTOR LUGS OF GROUPS OF BATTERY PLATES, COMPRISING THE STEPS OF FILLING AN OPEN TOP BATTERY POST STRAP MOLD WITH MOLTEN LEAD WHILE HEATING THE MOLD TO A TEMPERATURE OF THE ORDER OF THE MOLTEN LEAD THEREIN, IMMERSING APPROPRIATE CONNECTOR LUGS OF A GROUP OF BATTERY PLATES IN THE MOLTEN LEAD IN SAID MOLD, MAINTAINING SAID MOLD AT A TEMPERATURE HIGH ENOUGH TO KEEP THE LEAD MOLTEN
Claim 2
Independent Claim

Claim 3
Independent Claim
189 words
AN APPARATUS FOR CASTING BATTERY POST STRAPS ONTO BATTERY PLATES, COMPRISING MEANS FOR RELEASABLY SUPPORTING A GROUP OF BATTERY PLATES WITH THEIR CONNECTOR LUGS PROJECTING DOWNWARDLY IN ALIGNED RELATION, A MOLD MEMBER OF RELATIVELY HEAT CONDUCTIVE MATERIAL HAVING WALLS DEFINING AN OPEN TOP MOLD CAVITY FOR A BATTERY POST STRAP AND FORMED WITH A COOLANT PASSAGE IN SAID WALLS AT THE UPPER PORTION THEREOF, A RESERVOIR ADAPTED TO CONTAIN A POOL OF MOLTEN LEAD, MEANS FORMED FOR DIPPING SAID MOLD INTO SAID POOL OF MOLTEN LEAD AND FOR LIFTING SAID CAVITY INTO SURROUNDING RELATION TO THE BOTTOM ENDS OF SAID CONNECTOR LUGS WHEREBY THE LATTER WILL BE IMMERSED IN MOLTEN LEAD CONTAINED IN SAID CAVITY, HEAT EXCHANGER MEANS ADAPTED FOR SUPPLYING A STREAM OF COOLANT THROUGH SAID PASSAGE FOR RAPIDLY CHILLING SAID MOLD AND SOLIDIFYING THE MOLTEN LEAD, AND CONTROL MEANS FOR ACTIVATING SAID HEAT EXCHANGE MEANS A PRECISELY TIMED PERIOD AFTER SAID CONNECTOR LUGS ARE IMMERSED IN THE MOLTEN LEAD IN THE MOLD CAVITY SO AS TO SOLIDIFY THE BATTERY POST STRAP AT THE INSTANT A GOOD WELD IS OBTAINED AND BEFORE MATERIAL EROSION OF THE CONNECTOR LUGS.
Claim 4
Independent Claim

Claim 5
Dependent Claim
143 words
IN A MACHINE FOR CASTING BATTERY STRAPS ONTO BATTERY PLATE CONNECTOR LUGS BY DIPPING A MOLD HAVING AN OPEN TOP MOLD CAVITY INTO A POOL OF MOLTEN LEAD AND LIFTING THE MOLD TO IMMERSE THE CONNECTING LUGS IN THE MOLTEN LEAD CONTAINED IN THE MOLD CAVITY, A MOLD STRUCTURE COMPRISING A MOLD MEMBER HAVING WALLS DEFINING AN OPEN TOP MOLD CAVITY, SAID WALLS BEING FABRICATED OF RELATIVELY HEAT CONDUCTIVE MATERIAL AND FORMED FOR RAPID HEATING AND COOLING, SAID MOLD MEMBER BEING ADAPTED TO ACQUIRE SUFFICIENT HEAT FROM SAID POOL OF MOLTEN LEAD TO MAINTAIN THE LEAD CARRIED BY SAID MOLD MEMBER IN A MOLTEN STATE WHEN SAID CONNECTING LUGS ARE IMMERSED THEREIN, SAID MOLD MEMBER BEING FORMED WITH A COOLANT PASSAGE THROUGH SAID WALLS, AND MEANS FOR SELECTIVELY ADMITTING A STREAM OF LIQUID COOLANT AND A BLAST OF AIR TO SAID COOLANT PASSAGE.
