Abstract
Abstract A BALL CAGE RETAINS A PLURALITY OF BALLS BETWEEN AN INNER JOINT MEMBER AND AN OUTER JOINT MEMBER. GROOVES FORMED IN THE OUTER SURFACE OF THE INNER JOINT MEMBER, IN WHICH THE BALLS ARE SEATED, HAVE CENTER LINES WHICH EXTEND WITH THE RADIAL DISTANCE OF EACH OF THE CENTER LINES WHICH FROM THE AXIS OF THE INNER JOINT MEMBER GREATEST AT THE ENDS AND DECREASING TOWARD THE CENTER OF THE CENTER LINE. THE CENTERS OF THE SPHERICAL INNER AND OUTER SURFACES OF THE BALL CAGE ARE ON THE AXIS OF THE BALL CAGE EQUIDISTANT FROM AND ON OPPOSITE SIDES OF A PLANE THROUGH THE CENTERS OF THE BALLS OR COINCIDENT IN SAID PLANE. IN THE LATTER CASE SAID GROOVES HAVE TO BE DISPOSED IN HELICES OF THE SAME AND OPPOSITE PITCH IN THE INNER AND OUTER JOINT MEMBERS. THIS ARRANGEMENT OF THE GROOVES IS ALSO POSSIBLE IN THE FIRST MENTIONED CASE.
