Magnetic ball with particular mounting for the magnet thereof

Claim 1

IN A MAGNETIC AMUSEMENT DEVICE OF THE CHARACTER DESCRIBED, A HOLLOW SPHERICAL MAGNET-CONTAINING BALL, SAID BALL BEING COMPRISED OF FIRST AND SECOND SEMI-SPHERICAL SHELL-HALVES FORMED OF LIGHTWEIGHT NON-MAGNETIC MATERIAL, PRESENTING OPEN CIRCULAR RIMS IN COEXTENSIVE ABUTTING RELATIONSHIP, AND PRODUCING TOGETHER A HOLLOW CLOSED SPHERICAL SHELL, AN INSIDE ANNULAR RIM FLANGE ON SAID FIRST SHELL-HALF, AN OUTSIDE ANNULAR RIM FLANGE ON SAID SECOND SHELL-HALF, THE TWO RIM FLANGES OVERLAPPING EACH OTHER AND THE COMBINED THICKNESS OF THE TWO RIM FLANGES BEING EQUAL TO THE RADIAL THICKNESS OF EACH SHELL-HALF, THE RIM REGIONS OF EACH SHELL-HALF BEING FORMED WITH AN INTERNAL SHALLOW SEMICIRCULAR SOCKET-HALF, THE TWO SOCKET-HALVES BEING IN CIRCUMFERENTIAL REGISTER AND, IN COMBINATION, PRODUCING AN INTERNAL SHALLOW CIRCULAR SOCKET AT THE REGION OF JUNCTURE BETWEEN THE TWO SHELL-HALVES, SAID SOCKET BEING PROVIDED WITH A CONTINUOUS FLAT BOTTOM WHICH EXTENDS ACROSS THE JUNCTURE REGION BETWEEN THE TWO SHELL-HALVES, THE DEPTH OF SAID SOCKET BEING SLIGHTLY IN EXCESS OF THE THICKNESS OF THE INSIDE RIM FLANGE OF THE FIRST SHELL-HALF SO THAT THE SOCKET EXTENDS INTO THE OUTSIDE RIM FLANGE OF THE SECOND SHELL-HALF AND RELIEVES A LIMITED INSIDE PORTION THEREOF WHILE AT THE SAME TIME RELIEVING SPACED REGIONS OF THE INSIDE RIM FLANGE OF THE FIRST SHELL-HALF WITH THE INTERVENING PORTION OF SAID INSIDE RIM FLANGE BETWEEN SAID SPACED RELIEVED REGIONS CONSTITUTING A THIN LOCKING TONGUE AND HAVING A CROSS-SECTIONAL CONFIGURATION IN THE FORM OF A HALF-MOON, A PORTION OF THE OUTSIDE ANNULAR RIM FLANGE BEING RELIEVED ON THE INNER SIDE THEREOF TO PROVIDE A SHALLOW RECESS CONFORMABLE IN CONFIGURATION TO THE CONFIGURATION OF SAID LOCKING TONGUE AND WITHIN WHICH RECESS THE LOCKING TONGUE IS RECEIVED AND SUBSTANTIALLY COMPLETELY FILLED THEREBY, A GENERALLY CYLINDRICAL PERMANENT MAGNET OF THE BARIUM FERRITE TYPE, HAVING CYLINDRICAL POLE FACES AT THE OPPOSITE ENDS THEREOF AND OF OPPOSITE POLARITY, DISPOSED WITHIN SAID SHELL AND HAVING ONE END FACE THEREOF SEATED WITHIN SAID SOCKET SO THAT THE AXIS OF THE MAGNET EXTENDS RADIALLY OF THE SHELL, EACH SHELL-HALF BEING FORMED WITH A PAIR OF SPACED PARALLEL FLAT INTERNAL WEBS HAVING EDGES WHICH ENGAGE AND EXTEND LONGITUDINALLY ALONG THE OUTSIDE CYLINDRICAL SURFACE OF THE MAGNET SUBSTANTIALLY COEXTENSIVELY WITH THE LENGTH THEREOF, THE WEBS OF THE TWO SHELL-HALVES SERVING TO STRADDLE THE MAGNET AND CONFINE THE SAME THEREBETWEEN, EACH SHELL-HALF BEING FORMED WITH A THIRD INTERNAL WEB EXTENDING AT A RIGHT ANGLE TO AND BRIDGING THE DISTANCE BETWEEN THE TWO WEBS OF THE ASSOCIATED SHELL-HALF, THE THIRD WEBS OF THE TWO SHELL-HALVES MAKING TANGENTIAL CONTACT WITH THE END REGION OF THE MAGNET REMOTE FROM THE SEATED END FACE OF THE MAGNET, THE AXIAL EXTENT OF SAID MAGNET BEING LESS THAN THE RADIUS OF THE SHELL.
