Methods of constructing elements having low friction pressure engagement

Claim 1

THE METHOD OF FORMING A BALL JOINT HAVING A BALL OF A STUD AND BALL JOURNALED IN A TWO-PIECE STAMPED HOUSING WHEREIN ONE STAMPING IS GENERALLY SEMISPHERICAL IN SHAPE HAVING AN APERTURE NEAR THE DOME THEREOF AND THE OTHER STAMPING IS GENERALLY TRUNCATED SPHERICAL IN SHAPE HAVING AN ENLARGED OPENING IN THE LOWER PORTION THEREOF, WHICH INCLUDES THE STEPS OF, POSITIONING A CAP OF LOW FRICTION MATERIAL ABOUT SAID BALL, POSITIONING SAID ONE STAMPING LOOSELY OVER THE DOME OF SAID BALL, POSITIONING SAID SECOND STAMPING OVER THE REMAINING PORTION OF THE BALL WITH THE STUD PROJECTING THROUGH SAID OPENING, SECURING SAID STAMPINGS TOGETHER TO FORM A HOUSING LOOSELY DISPOSED ABOUT THE BALL, SUPPORTING SAID STUD IN AN ARBOR HAVING AN ANNULAR UPPER END PORTION ENCIRCLING THE STUD NEAR THE JUNCTURE OF THE BALL AND THE STUD AND PINCHING SAID CAP AGAINST THE SURFACE OF THE BALL TO RETAIN IT IN POSITION, SUPPORTING SAID OTHER STAMPING ON THE OUTER PERIPHERY OF SAID ANNULAR UPPER END PORTION OF THE ARBOR IN A MANNER TO CLOSE OFF SAID OPENING AND TO CENTRALLY POSITION THE BALL AND HOUSING, MOVING AN INJECTING NOZZLE BETWEEN THE BALL AND HOUSING, MOVING AN INJECTING NOZZLE INTO ENGAGEMENT WITH SAID ONE STAMPING AND COMMUNICATION WITH SAID APERTURE IN A MANNER TO FORCE SAID OTHER STAMPING FIRMLY AGAINST THE SUPPORTING ARBOR, AND INJECTING HARDENABLE MATERIAL THROUGH SAID NOZZLE AND APERTURE INTO THE HOUSING TO FILL SAID SPACE BETWEEN THE BALL AND HOUSING AND ACCURATELY CONFORMING SAID CAP TO THE SURFACE OF THE BALL UNDER PRESSURE.
