Self-rimming porcelain enameled sink
Abstract
Abstract AN IMPROVED SELF-RIMMING PORCELAIN ENAMELED SINK INCLUDING A NOVEL CLAMPING CHANNEL USED FOR SECURING THE PORCELAIN ENAMELED SINK IN A COUNTER TOP. THE CLAMPING CHANNEL IS MOUNTED ON THE UNDERSIDE OF THE SINK AND COOPERATES WITH A LUG THAT ENGAGES THE UNDERSIDE OF THE COUNTER TOP TO SECURE THE SINK IN THE COUNTER TOP. A STAINLESS STEEL BEAD IS BONDED COMPLETELY AROUND THE PERIPHERAL EDGE OF THE PORCELAIN ENAMELED SINK SO THAT THIS BEAD PROTECTS THE EDGE DURING INSTALLATION AND USAGE AND SO THAT THE COMBINED EDGE-BEAD WILL EXTEND FROM THE SINK A SUFFICIENT DISTANCE TO COVER THE RAGGED EDGES OF THE HOLE IN THE COUNTER TOP IN WHICH THE SINK IS MOUNTED. A TIGHT WATER SEAL IS FORMED BETWEEN THE BEAD AND THE COUNTER TOP.
