Permanent magnetic block

Claim 1

FOR USE ON A HORIZONTALLY DISPOSED MAGNETIC FLUX HOLDING SURFACE, A PERMANENT MAGNET BLOCK SUPPORT FOR MOUNTING A SMALL WORK PIECE OVER A CENTRAL OPEN AREA WHICH COMPRISES THREE IDENTICAL PERMANENT MAGNET BLOCKS CLOSELY GROUPED ON SAID MAGNETIC HOLDING SURFACE ABOUT A FOCAL POINT AT EQUAL DISTANCES FROM SAID FOCAL POINT PROVIDING A CENTRAL OPEN AREA AND SPACED AT EQUAL DISTANCES FROM ONE ANOTHER AND IN IDENTICAL ANGULAR POSITIONS ABOUT SAID FOCAL POINT IN WHICH A CORRESPONDING MAGNET FLUX HOLDING SURFACE OF EACH SAID BLOCK IS MOST NEARLY ADJACENT SAID FOCAL POINT, EACH SAID BLOCK COMPRISING A ROTATABLE CYLINDRICAL MAGNET EXTENDING THE LENGTH OF THE BLOCK CENTRALLY THEREOF, SAID CYLINDRICAL MAGNET BEING MAGNETIZED SO THAT THE POLES OF SAID CYLINDRICAL MAGNET ARE ON OPPOSITE SIDES OF THE MAGNET AND EXTEND LONGITUDINALLY THEREOF, SPACER SEPARATED FLUX BEARING SEGMENTS PROVIDING A SUBSTANTIAL HOLDING FLUX RECEIVING BASE AREA, AND RECTANGULARLY DISPOSED EXTERNAL TOP, SIDE AND END SURFACES OF SAID BLOCK, A HORIZONTAL BORE RECEIVING SAID CYLINDRICAL MAGNET THROUGH A PORTION OF SAID BLOCK ABOVE SAID HOLDING FLUX RECEIVING BASE AREA, A SPACER EXTENDING FROM SAID BORE AND INTERSECTING SAID TOP SURFACE ADJACENT THE EDGE OF SAID TOP SURFACE FORMED WITH ONE SIDE OF THE BLOCK PROVIDING A MAGNET FLUX HOLDING AREA ACROSS SAID SPACER IN SAID TOP SURFACE ADJACENT SAID EDGE ALONG THE LENGTH OF THE BLOCK, A SECOND SPACER EXTENDING FROM THE OPPOSITE SIDE OF SAID BORE AND INTERSECTING THE SIDE SURFACE OPPOSITE SAID ABOVE-MENTIONED SIDE SURFACE PROVIDING A MAGNET FLUX HOLDING AREA ACROSS SAID SPACER IN SAID LAST MENTIONED SIDE SURFACE ALONG THE LENGTH OF THE BLOCK, CORRESPONDING VERTICAL CORNERS BETWEEN EACH SAID SIDE SURFACE AND AN END SURFACE OF EACH SAID BLOCK BEING BEVELLED TO FACILITATE SAID CLOSE GROUPING OF SAID BLOCKS.
