Apparatus for cutting coiled metal strip into sheets

Claim 1

AN APPARATUS FOR CUTTING A COIL OF METAL STRIP INTO SHEETS COMPRISING A PLATFORM, A VERTICAL SUPPORT AT ONE SIDE OF SAID PLATFORM, A MANDREL SPACED VERTICALLY ABOVE SAID PLATFORM FOR SUPPORTING SAID COIL IN A HORIZONTAL POSITION OVER SAID PLATFORM, SAID MANDREL HAVING A SUPPORTING CONNECTION AT ITS INNER END WITH SAID VERTICAL SUPPORT AND PROJECTING HORIZONTALLY OUTWARDLY THEREFROM FOR SUPPORTING ENGAGEMENT WITH THE INNERMOST CONVOLUTION OF SAID COIL, AND COIL CUTTING MEANS COMPRISING AN ENDLESS CONVEYOR MOUNTED ABOVE SAID MANDREL AND HAVING A LOWER RUN PARALLEL TO THE AXIS OF AND SPACED RADIALLY OUTWARDLY FROM SAID COIL, SAID LOWER RUN LYING IN A VERTICAL PLANE CONTAINING THE SAID AXIS OF SAID COIL, A PLURALITY OF CUTTER ELEMENTS MOUNTED AT SPACED INTERVALS ALONG SAID ENDLESS CONVEYOR, MEANS FOR OPERATING SAID CONVEYOR CONTINUOUSLY TO MOVE SAID CUTTER ELEMENTS SUCCESSIVELY OVER SAID LOWER RUN, AND MEANS MOUNTING SAID CONVEYOR FOR VERTICAL MOVEMENT TO AN OPERATIVE CUTTING POSITION IN WHICH ITS SAID CUTTER ELEMENETS DURING MOVEMENT OVER SAID LOWER RUN HAVE CUTTING ENGAGEMENT WITH THE OUTERMOST CONVOLUTION OF SAID COIL ALONG AN AXIAL PATH IN SAID VERTICAL PLANE AND ABOVE SAID MANDREL, SAID CONVEYOR MOUNTING MEANS COMPRISING A PARALLELOGRAM LINKAGE COMPRISING SPACED UPPER AND LOWER PIVOTS ON SAID VERTICAL SUPPORT DEFINING A FIXED LINK, A MOVABLE LINK PARALLEL TO SAID FIXED LINK, UPPER AND LOWER LINKS HAVING CONNECTIONS AT ONE END RESPECTIVELY WITH SAID SPACED PIVOTS AND PIVOTAL CONNECTIONS AT THEIR OTHER ENDS WITH OPPOSITE ENDS OF SAID MOVABLE LINK, AND A BRACKET SUPPORT FOR SAID CONVEYOR ON SAID MOVABLE LINK RENDERING ITS MOVEMENT IN RESPONSE TO PIVOTAL MOVEMENT OF SAID UPPER AND LOWER LINKS ABOUT SAID SPACED UPPER AND LOWER PIVOTS EFFECTIVE TO IMPART VERTICAL MOVEMENT TO SAID CONVEYOR.

Claim 2

AN APPARATUS FOR CUTTING A COIL OF METAL STRIP INTO SHEETS COMPRISING A PLATFORM, A VERTICAL SUPPORT AT ONE SIDE OF SAID PLATFORM, A MANDREL SPACED VERTICALLY ABOVE SAID PLATFORM FOR SUPPORTING SAID COIL IN A HORIZONTAL POSITION OVER SAID PLATFORM, SAID MANDREL HAVING A SUPPORTING CONNECTION AT ITS INNER END WITH SAID VERTICAL SUPPORT AND PROJECTING HORIZONTALLY OUTWARDLY THEREFROM FOR SUPPORTING ENGAGEMENT WITH THE INNERMOST CONVOLUTION OF SAID COIL, AND COIL CUTTING MEANS COMPRISING AN ENDLESS CONVEYOR MOUNTED ABOVE SAID MANDREL AND HAVING A LOWER RUN PARALLEL TO THE AXIS OF AND SPACED RADIALLY OUTWARDLY FROM SAID COIL, SAID LOWER RUN LYING IN A VERTICAL PLANE CONTAINING THE SAID AXIS OF SAID COIL, A PLURALITY OF CUTTER ELEMENTS MOUNTED AT SPACED INTERVALS ALONG SAID ENDLESS CONVEYOR, MEANS FOR OPERATING SAID CONVEYOR CONTINUOUSLY TO MOVE SAID CUTTER ELEMENTS SUCCESSIVELY OVER SAID LOWER RUN, AND MEANS MOUNTING SAID CONVEYOR FOR VERTICAL MOVEMENT TO AN OPERATIVE CUTTING POSITION IN WHICH ITS SAID CUTTER ELEMENETS DURING MOVEMENT OVER SAID LOWER RUN HAVE CUTTING ENGAGEMENT WITH THE OUTERMOST CONVOLUTION OF SAID COIL ALONG AN AXIAL PATH IN SAID VERTICAL PLANE AND ABOVE SAID MANDREL, SAID CONVEYOR MOUNTING MEANS COMPRISING A PARALLELOGRAM LINKAGE COMPRISING SPACED UPPER AND LOWER PIVOTS ON SAID VERTICAL SUPPORT DEFINING A FIXED LINK, A MOVABLE LINK PARALLEL TO SAID FIXED LINK, UPPER AND LOWER LINKS HAVING CONNECTIONS AT ONE END RESPECTIVELY WITH SAID SPACED PIVOTS AND PIVOTAL CONNECTIONS AT THEIR OTHER ENDS WITH OPPOSITE ENDS OF SAID MOVABLE LINK, AND A BRACKET SUPPORT FOR SAID CONVEYOR ON SAID MOVABLE LINK RENDERING ITS MOVEMENT IN RESPONSE TO PIVOTAL MOVEMENT OF SAID UPPER AND LOWER LINKS ABOUT SAID SPACED UPPER AND LOWER PIVOTS EFFECTIVE TO IMPART VERTICAL MOVEMENT TO SAID CONVEYOR.
