Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
APPARATUS FOR USE IN FORMING A CONTINUOUS STRAND OF CAST METAL COMPRISING: (A) AN OSCILLATABLE VERTICAL MOLD HAVING PLANAR SURFACES FORMING A MOLD CAVITY AND A SUBSTANTIALLY VERTICAL AXIS; (B) MEANS FOR POURING MOLTEN METAL INTO THE MOLD AND FORMING THEREIN A CONTINUOUS STRAND OF CAST METAL; (C) MEANS FOR CONTINUOUSLY WITHDRAWING THE STRAND FROM THE MOLD; AND (D) STRAND SUPPORTING MEANS HAVING AN ARCUATE AXIS LYING SUBSTANTIALLY IN THE PLANE OF THE VERTICAL AXIS AND DISPOSED CONCAVELY THERETO SO AS TO INTERSECT THE VERTICAL AXIS AT A POINT BELOW THE BOTTOM OF THE MOLD, SAID STRAND SUPPORTING MEANS URGING ONE SURFACE OF SAID STRAND AGAINST ONE WALL OF THE MOLD WHEREBY SAID SURFACE IS COOLED SUBSTANTIALLY MORE THAN ANOTHER OPPOSITE SURFACE AND THE STRAND THERMALLY BENDS AWAY FROM SAID COOLER SURFACE.
Claim 2
Dependent Claim

Claim 3
Independent Claim
104 words
A METHOD FOR FORMING A CONTINUOUS STRAND OF CAST METAL COMPRISING THE STEPS OF: (A) POURING MOLTEN METAL INTO AN OSCILLATABLE VERTICAL MOLD HAVING PLANAR SURFACES FORMING A MOLD CAVITY AND A SUBSTANTIALLY VERTICAL AXIS, AND FORMING IN SAID MOLD A CONTINUOUS STRAND OF METAL; (B) CONTINUOUSLY WITHDRAWING THE STRAND FROM THE MOLD; AND (C) URGING SAID STRAND LATERALLY TOWARD SAID MOLD SO THAT ONE SURFACE OF SAID STRAND IS COOLED UPON CONTACTING A COOLED WALL WITHIN SAID MOLD WHEREBY SAID STRAND THERMALLY BENDS AWAY FROM THE COOLED SURFACE OF SAID STRAND AND AWAY FROM A VERTICAL DOWN WARD DIRECTION TOWARD A HORIZONTAL ATTITUDE.
