Magnetic separator and conveyor

Claim 1

APPARATUS FOR SEPARATING MAGNETIC AND NON-MAGNETIC SOLIDS JOINTLY FROM LIQUID WASTES, SUCH AS COOLANTS AND CUTTING OILS, COMPRISING A TUBE OF NON-MAGNETIC MATERIAL HAVING INLET MEANS THROUGH WHICH THE WASTE ENTERS THE TUBE FROM A SOURCE OF SUCH WASTE, OUTLET MEANS FOR CLEAN LIQUID, AND DISCHARGE MEANS FOR SOLIDS SEPARATED FROM SAID LIQUID WASTES, SAID INLET MEANS BEING LOCATED BETWEEN SAID CLEAN LIQUID OUTLET MEANS AND SAID SOLIDS DISCHARGE MEANS, AND SAID CLEAN LIQUID OUTLET MEANS AND SOID SOLIDS DISCHARGE MEANS LEADING FROM OPPOSED END PORTIONS OF SAID TUBE, A FLEXIBLE COIL OF NON-MANGETIC MATERIAL IN SAID TUBE AND EXTENDING AT LEAS FROM SAID CLEAN LIQUID OUTLET MEANS TO SAID SOLIDS DISCHARGE MEANS, SAID COIL BEING FLEXIBLE OVER ITS ENTIRE LENGTH AND HAVING A FREE END ADJACENT SAID DISCHARGE MEANS, WHEREBY IT CAN EXPAND UNDER LOAD TO EXTEND BEYOND SAID DISCHARGE MEANS, MOTOR MEANS FOR ROTATING SAID COIL IN SAID TUBE AND CONNECTED TO THE OTHER END OF SAID COIL, AND MAGNETS MOUNTED ON THE OUTSIDE OF SAID TUBE BETWEEN SAID INLET PORT AND SAID CLEAN LIQUID OUTLET MENS, WITH THEIR OPPOSITE POLES IN FACING RELATION, SAID MAGNETS ESTABLISHING A MAGNETIC FIELD IN SAID TUBE WHEREBY MAGNETIC SOLIDS ARE ATTRACTED TO AND FORM A LAYER ON THE INNER WALL OF SAID TUBE IN WHICH LAYER NON-SETTABLE NON-MAGNETIC SOLIDS ARE ENTRAPPED, SAID COIL BEING ADAPTED UPON ITS ROTATION, TO JOINTLY MOVE SOLIDS ATTRACTED TO THE INNER WALL OF SAID TUBE BY THE MAGNETIC FIELD SET UP BY SAID MAGNETS AND NON-MAGNETIC SOLIDS INTERMESHED THEREWITH, AS WELL AS ANY MAGNETIC AND NON-MAGNETIC SOLIDS SETTLED IN SAID TUBE ALONG SAID TUBE TO SAID SOLIDS DISCHARGE MEANS.
