Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
145 words
IN A FRICTION WELDING MACHINE HAVING A ROTATING CHUCK, A SPINDLE ON WHICH SAID ROTATING CHUCK IS FIXED, A HOUSING, BEARING MEANS ROTATABLY SUPPORTING SAID SPINDLE WITHIN SAID HOUSING, A SECOND CHUCK, AND MEANS URGING SAID SECOND CHUCK AND SAID ROTATING CHUCK TOWARDS EACH OTHER TO ACCOMPLISH A FRICTION WELD; MEANS COUNTERACTING AXIAL THRUST EXERTED ON SAID SPINDLE COMPRISING, IN COMBINATION, AN ANNULAR PROJECTION FIXED TO SAID SPINDLE EXTENDING OUTWARD FROM SAID SPINDLE, A CYLINDRICAL INNER SURFACE OF SAID HOUSING DISPOSED ABOUT SAID ANNULAR PROJECTION, MEANS EXTENDING INWARD FROM SAID CYLINDRICAL INNER SURFACE TOWARD SAID SPINDLE, SAID ANNULAR PROJECTION FIXED TO SAID SPINDLE BEING DISPOSED BETWEEN SAID ROTATING CHUCK AND SAID MEANS EXTENDING INWARD FROM SAID CYLINDRICAL INNER SURFACE, AND MEANS INTRODUCING FLUID UNDER PRESSURE BETWEEN SAID ANNULAR PROJECTION AND SAID MEANS EXTENDING INWARD FROM SAID CYLINDRICAL INNER SURFACE AS SAID CHUCKS ARE URGED TOGETHER.

Claim 3
Independent Claim
95 words
A METHOD OF FRICTION WELDING COMPRISING FIXING TWO WORKPIECES IN JUXTAPOSED AXIALLY ALIGNED CHUCKS, MOVING THE WORKPIECES INTO CONTACT WITH EACH OTHER, ROTATING THE WORKPIECES RELATIVE TO EACH OTHER BY FORCE TRANSMITTED THROUGH A FIRST CLUTCH CONNECTED TO A FLYWHEEL MASS AND A SECOND CLUTCH CONNECTING SAID FLYWHEEL MASS AND ONE WORKPIECE, SENSING THE ROTATIONAL SPEED OF SAID FLYWHEEL MASS, DISENGAGING SAID FIRST CLUTCH IN RESPONSE TO A SELECTED DETECTED SPEED OF SAID FLYWHEEL MASS, AND THEREAFTER DISENGAGING SAID SECOND CLUTCH IN RESPONSE TO DETECTION OF A SPEED INCLUDING STOPPING LOWER THAN SAID SELECTED SPEED.
