Method of coupling articles of unlike materials

Abstract

Abstract THE DISCLOSED METHOD IS ADVANTAGEOUS FOR COUPLING GLASS TO METAL PARTS AND PARTICULARLY SO FOR CREATING IMPROVED WINDOW OR WINDSHIELD INSTALLATIONS. THE METHOD UTILIZES, AS A BONDING ELEMENT, AN ELONGATE THERMO-PLASTIC OR EQUIVALENT STRIP MATERIAL SO STRUCTURED TO PROVIDE THAT ON APPLICATION THERETO OF HEAT IN THE RANGE FROM ABOUT 300* TO ABOUT 500*F. THAT THE SURFACE AND ONLY THE SURFACE THEREOF BECOMES FLUIDLY ADHESIVE AND PARTICULARLY ADAPTED THEREBY TO QUICKLY FORM A READY BOND AND A CLEAN SEAL BETWEEN GLASS AND/OR METAL PARTS. WHILE UNDER THE APPLICATION OF HEAT, IN THE RANGE SPECIFIED, THE SURFACE OF THE STRIP BECOMES FLUIDLY ADHESIVE, THE INNER PORTION OF THE BODY THEREOF RETAINS AN ESSENTIALLY STABLE FORM, THROUGH MODIFIED TO A CONDITION TO ENABLE SAID STRIP TO ACCOMMODATE AND PLASTICALLY CONFORM TO THE CONTOUR OF AN APPLIED LOAD. IN PRACTICE OF THE DISCLOSED METHOD, THE STRIP IS MOUNTED TO ONE OF THE UNLIKE PARTS TO BE COUPLED AND HAS PLACED THEREAGAINST SURFACE PORTIONS OF THE OTHER PART. WHILE IN SUCH POSITION, THE STRIP MATERIAL IS HEATED TO ACHIEVE A TEMPERATURE FROM ABOUT 300* TO ABOUT 500*F. TO CAUSE ONLY THE SURFACE THEREOF TO BECOME FLUIDLY ADHESIVE, WHEREUPON THERE IS A QUICK AND CLEAN ADHESIVE CONTACT BETWEEN THE STRIP AND THE CONTACTING PORTIONS OF THE RELATIVELY ABUTTED DISSIMILAR PARTS. ON COOLING IN PLACE, THE STRIP PROVIDES A UNIQUELY COMPLETE AND EXTREMELY STRONG BOND AND SEAL BETWEEN THE PARTS.
