Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
74 words
IN A METHOD OF MAKING COPPER-LEAD BEARING, THE STEPS OF, MIXING PURE COPPER POWDER WITH COPPER LEAD POWDER WHEREIN THE LEAD IN THE FINISHED BEARING IS FROM 2.25 TO 38%, AND THEN HEATING THE MIXED POWDER AT A TEMPERATURE ABOVE THE MELTING POINT OF THE COPPER-LEAD POWDER AND BELOW 1981* F., FOR A TIME SUFFICIENT TO CAUSE THE COPPER-LEAD POWDER TO MELT AND TO COAT AND BOND THE PARTICLES OF THE COPPER POWDER TOGETHER.
Claim 2
Dependent Claim

IN A METHOD OF MAKING COPPER-LEAD BEARING, THE STEPS OF, MIXING PURE COPPER POWDER WITH COPPER LEAD POWDER WHEREIN THE LEAD IN THE FINISHED BEARING IS FROM 2.25 TO 38%, AND THEN HEATING THE MIXED POWDER AT A TEMPERATURE ABOVE THE MELTING POINT OF THE COPPER-LEAD POWDER AND BELOW 1981* F., FOR A TIME SUFFICIENT TO CAUSE THE COPPER-LEAD POWDER TO MELT AND TO COAT AND BOND THE PARTICLES OF THE COPPER POWDER TOGETHER.
Claim 3
Dependent Claim
169 words
THE PROCESS OF MAKING A COMPOSITE BEARING MEMBER, THE STEPS OF, MIXING COPPER-LEAD POWDER HAVING FROM 10 TO 40% LEAD THEREIN WITH CUPREOUS ALLOY POWDER OF HIGHER MELTING POINT THAN THE COPPER LEAD POWDER, WHEREIN THE QUANTITY OF COPPER LEAD POWDER IN THE TOTAL MIXTURE IS SUCH THAT THE LEAD CONTENT OF THE BEARING IS FROM 2.25 TO 38%, DISTRIBUTING SAID MIXED POWDERS UPON THE SURFACE OF A HIGHER MELTING POINT STRONG METAL SUPPORT, HEATING THE SUPPORT WITH THE POWDER THEREON AT A TEMPERATURE ABOVE THE MELTING POINT OF THE COPPER-LEAD POWDER AND BELOW THE MELTING POINT OF THE CUPREOUS ALLOY POWDER, FOR A TIME SUFFICIENT TO CAUSE THE COPPER-LEAD POWDER TO MELT AND TO COAT AND BOND THE PARICLES OF THE CUPREOUS ALLOY POWDER TOGETHER AND FORM A COPPER-LEAD LAYER HAVING A SUBSTANTIALLY UNIFORM DISTIRIBUTION OF LEAD THERETHROUGH AND SIMULTANEOUSLY TO CAUSE THE BONDED TOGETHER COPPER-LEAD LAYER TO MELTALLURGICALLY ATTACH ITSELF TO THE SURFACE OF THE SOLID METAL SPPORT, AND THEN COOLING THE COMPOSITE BEARING MEMBER SO FORMED.
