Continuously slipping magnetic clutch

Claim 1

A CONTINUOUSLY SLIPPING MAGNETIC CLUTCH COMPRISING: A DRIVE DISC FIXEDLY MOUNTED FOR ROTATION WITH A DRIVE SHAFT, SAID DRIVE DISC HAVING FORWARD AND REAR FACES AND INCLUDING AN INNER RADIAL PORTION OF MAGNETIC MATERIAL AND AN OUTER ANNULAR PORTION OF NON-MAGNETIC MATERIAL; A DRUM OF MAGNETIC MATERIAL MOUNTED FOR FREE ROTATION AROUND SAID DRIVE SHAFT ADJACENT TO SAID DRIVE DISC, SAID DRUM HAVING A FORWARD AND A REAR SURFACE, SAID FORWARD SURFACE INCLUDING AN ANNULAR SLOT DIVIDING SAID FORWARD SURFACE INTO INNER AND OUTER PLANAR SURFACES, SAID OUTER PLANAR SURFACE PROJECTING BEYOND THE PLANE OF SAID INNER PLANAR SURFACE; A FIRST FACING OF WEAR MATERIAL IMPRESSED ON SAID OUTER ANNULAR PORTION OF SAID DISC FLUSH WITH THE REAR FACE OF SAID DRIVE DISC; A SECOND FACING OF WEAR MATERIAL IMPRESSED ON SAID OUTER PLANAR SURFACE OF SAID DRUM, A ONE ON SAID FACINGS COMPRISING A HARD WEAR MATERIAL AND THE OTHER COMPRISING A SOFT WEAR MATERIAL, SAID FIRST AND SECOND FACINGS BEING POSITIONED IN CONTINUOUS SLIPPING FRICTION CONTACT TO CAUSE SAID DRUM TO TEND TO ROTATE WITH SAID DRIVE DISC, THE CONTACTING WEAR MATERIALS MAINTAINING AN AIR GAP BETWEEN SAID INNER PLANAR SURFACE OF SAID DRUM AND SAID REAR FACE OF SAID DRIVE DISC; A BOBBIN ARRANGEMENT MOUNTED WITHIN SAID ANNULAR SLOT FOR ROTATION WITH SAID DRUM; AN ELECTRICAL COIL WOUND AROUND SAID BOBBIN FOR GENERATING A MAGNETIC FIELD THROUGH SAID DRUM AND DRIVE DISC WHEN SAID COIL IS ENGERIZED BY AN ELECTRIC CURRENT; A DRIVEN DISC OF NONMAGNETIC MATERIAL HAVING FORWARD AND REAR SURFACES, SAID DRIVEN DISC INCLUDING AN ANNULAR FLANGE AT A RADIAL EXTREMITY OF ITS FORWARD SURFACE AND A COLLAR HAVING A LONGITUDINAL SLOT THEREIN SURROUNDING A HOLE WHICH IS CENTRALLY DISPOSED IN SAID DRIVEN DISC TO RECEIVE SAID DRIVE SHAFT, SAID FLANGE BEING POSITIONED IN PRESSURE CONTACT WITH AN OUTER SURFACE OF SAID DRUM TO CAUSE SAID DRIVEN DISC TO ROTATE WITH SAID DRUM; A SPACER DISC MOUNTED ON SAID COLLAR IN PRESSURE CONTACT WITH THE REAR SURFACE OF SAID DRIVEN DISC, SAID SPACER DISC HAVING A SLOT EXTENDING RADIALLY FROM SAID COLLAR; A FLEXIBLE CONDUCTOR EXTENDING AROUND SAID COLLAR AND THROUGH THE RADIAL SLOT; MEANS FOR CONNECTING SAID CONDUCTOR TO SAID COIL TO ENERGIZE SAID COIL IN RESPONSE TO CURRENT SIGNALS APPLIED TO SAID CONDUCTOR; A CIRCULAR SPRING CLIP HAVING ONE END POSITIONED IN SAID LONGITUDIAL SLOT AND EXTENDING AROUND SAID COLLAR TO SECURE A FIRST TURN OF SAID CONDUCTOR AROUND SAID COLLAR; AND MEANS POSITIONED AROUND THE END OF SAID COLLAR TO MAINTAIN SAID CONDUCTOR IN A SPIRAL WRAP AROUND SAID COLLAR WHEN SAID DRUM IS ROTATED.
