Method of making composite electrical contact bodies

Claim 1

THE METHOD OF FORMING A UNITARY ELECTRICAL CONTACT COMPRISING THE STEPS OF CUTTING A FIRST BODY FROM RAW STOCK AND APPLYING A PLUNGER THERETO TO PASS SAID FIRST BODY THROUGH A FIRST DIE DIE AND INTO A SECOND DIE SPACED FROM SAID FIRST DIE WHEREBY SAID PLUNGER FORMS AN OPENING IN ONE END OF SAID FIRST BODY AND THE OTHER END OF SAID FIRST BODY IS ENLARGED BY PRESSING AGAINST SAID SECOND DIE, AND THEREAFTER REMOVING SAID PLUNGER AND CUTTING A SECOND BODY FROM RAW STOCK, PRESSING SAID SECOND BODY INTO SAID OPENING IN SAID FIRST BODY WHILE EXERTING A PRESSURE OF AT LEAST 2000 POUNDS PER SQUARE INCH ON SAID BODIES TO CAUSE A PORTION OF SAID FIRST BODY AND EFFECT AN INTERFACIAL BONDING AND ALLOYING BETWEEN THE ABUTTING SURFACES OF SAID FIRST AND SECOND BODIES BY MOVING SAID FIRST AND SECOND DIES TOWARD ONE ANOTHER; SAID BONDING AND ALLOYING OCCURRING WITHIN A PERIOD NOT LONGER THAN 2 SECONDS AFTER CUTTING OF SAID SECOND BODY FROM STOCK; AND HEATING THE RESULTING ELECTRICAL CONTACT TO A TEMPERATURE OF 1000*F. TO 1600*F. TO COMPLETE THE EUTECTIC BONDING OF SAID FIRST AND SECOND BODIES THEREIN.
