Magnetic separator having field shaping poles

Claim 1

A MAGNETIC SEPARATOR COMPRISING: A BACK BAR, SPACED PERMANENT MAIN MAGNETS FIXED TO SAID BACK BAR, AND SAID MAGNETS HAVING A FACE SPACED FROM SAID BACK BAR, SAID MAIN MAGNETS EACH HAVING A MAGNETIC POLE ADJACENT ITS SAID FACE OF OPPOSITE POLARITY FROM THE POLE OF THE MAIN MAGNET ADJACENT THERETO, REPELLING MAGNETS DISPOSED BETWEEN SAID MAIN MAGNETS, MEANS TO DIRECT A STREAM CONTAINING NONMAGNETIC MATERIAL AND MAGNETIC MATERIAL IN CLOSE PROXIMITY TO SAID FACES OF SAID MAGNETS AND THROUGH MAGNETIC FIELDS PRODUCED BY SAID MAIN MAGNETS, WHEREBY SAID MAGNETIC MATERIAL IS SEPARATED FROM SAID NONMAGNETIC MATERIAL, SAID REPELLING MAGNETS EACH HAVING A MAGNETIC POLE AT EACH SIDE THEREOF OF LIKE POLARITY TO THE POLE OF THE MAIN MAGNET AT SAID FACE THEREOF, WHEREBY THE LEAKAGE FIELD OF SAID MAIN MAGNETS IS REPELLING AND REINFORCES THE NORMAL FIELD WHICH IS FORCED OUTWARD TOWARD SAID STREAM OF MATERIAL, A PLURALITY OF BUCKING MAGNETS BEING DISPOSED IN AN ARCUATE PATTERN OUTSIDE OF SAID MAIN MAGNETS WITH ONE POLE OF EACH SAID BUCKING MAGNET DIRECTLY OPPOSITE AND FACING A LIKE POLE OF SAID MAIN MAGNET.
