Abstract
Abstract A PAINT ROLLER CLEANING DEVICE COMPRISES A HOLLOW CYLINDER HAVING A HELICAL PROJECTION EXTENDING FROM THE INNER SURFACE OF THE CYLINDER. A PAINT TO BE CLEANED IS CONTAINED WITHIN THE CYLINDER AND IS ROTATED BY AN ELECTRIC MOTOR OR THE LIKE. ONE END OF THE CYLINDER EXTENDS INTO A POOL OF CLEANING FLUID, AND AS THE ROLLER IS ROTATED, FLUID IS SUCKED INTO THE DEVICE THROUGH ONE APERTURE AND EXPELLED THROUGH ANOTHER APERTURE AT THE OPPOSITE END. AS THE ROLLER ROTATES, THE HELICAL PROJECTION COMPRESSES IT TO SQUEEZE RESIDUAL PAINT FROM IT AS IT IS BEING WASHED BY THE CLEANING FLUID. METHODS FOR MAKING SUCH APPARATUS ARE DESCRIBED.
