Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
166 words
A DRY CELL BATTERY, COMPRISING A CARBON CUP HAVING A HOLLOW BODY, A COLOSED END AND AN OPEN END, A CARBON ROD PROJECTING FROM SAID CLOSED END AND DEPOSED GENERALLY ALONG THE LONGITUDINAL AXIS OF SAID CUP AND BEING ELECTRICCALLY CONNECTED THERETO, SAID CUP AND SAID ROD FORMING A CATHODE STRUCTURE, A HOLLOW ANNULAR METALLIC ANODE DISPOSED BETWEEN SAID ROD AND SAID CAP AND BEING SUBSTANTIALLY CONCENTRIC THEREWITH, SAID ANODE BEING FORMED FROM A METAL WHICH INCREASES SUBSTANTIALLY IN VOLUME AS A RESULT OF THE CHEMICAL REACTION OCCURRING DURING THE DISCHARGE OF SAID BATTERY, CLOSURE MEANS FOR SAID OPEN END OF SAID CUP. BATTERY MIX CONTAINED IN THE SPACE BETWEEN SAID ANODE AND SAID CUP AND SAID ROD TO REACT CHEMICALLY WITH SAID ANODE WHEN SAID AMODE AND SIDE CATHODE STRUCTURE ARE ELECTRICALLY CONNECTED THROUGH AN EXTERNAL CIRCUIT, SAID CHEMICAL REACTION PRODUCING A SUBSTANTIALY INCREASE IN THE VOLUME OF MATERIAL WITHIN SAID CELL THEREBY PRODUCING A TRANSVERSE STREE TENDING TO REPTURE SAID CUP, AND REINFORCING MEANS
